2. Materials and Methods
2.1. Design
This study employed a group-randomized controlled trial to explore students’ motor (soccer-pass performance), cognitive (inhibition and cognitive flexibility), and metacognitive (calibration accuracy) responses under three different teaching styles (i.e., self-check, command, and practice) during a single soccer session in physical education. In particular, intact fifth- and sixth-grade classes were randomly allocated to one of the following groups: (a) Group 1 with the self-check style, (b) Group 2 with the command style, (c) Group 3, with the practice style, and (d) Group 4, a control group. Measures for soccer-pass performance, estimation of soccer-pass performance, and design fluency were involved before and after the soccer session.
2.2. Participants and Settings
Participants were 147 students (Mage = 10.88, SD = 0.56, 72 boys, 75 girls) attending four fifth-grade (80 students) and four sixth-grade (67 students) classes of four elementary schools. In particular, Group 1 (self-check style) consisted of 38 students (19 boys), Group 2 (command style) of 34 students (16 boys), Group 3 (practice style) of 34 students (16 boys), and Group 4 (control group) of 41 students (21 boys). To enhance the ecological validity of the study, given that students are taught in intact classes at school, randomization was conducted first at the school level and then at the grade level. Specifically, schools were randomly allocated to one of the four groups of the study, and then two classes (one fifth-grade and one sixth-grade) from each elementary school were randomly selected. This procedure was adopted to prevent the leakage of experimental conditions between groups employing different teaching styles within the same school and to avoid having the same teachers teach groups assigned to different teaching styles. The elementary schools involved in this study were located in the same city and shared similar characteristics, including a comparable number of students and classes, similar sports facilities, and teachers with similar levels of teaching experience.
In Greece, fifth- and sixth-grade students attend two compulsory 45 min physical education lessons per week, taught by certified physical education specialists. The curriculum emphasizes the development of fundamental motor and sports skills and encourages the use of a variety of instructional approaches, including the Spectrum of Teaching Styles.
2.3. Measures
2.3.1. Soccer-Pass Performance
Students’ soccer-pass performance was measured with a passing-accuracy test (
Ali, 2011). In particular, students performed 10 passes, with no time limit, from a distance of 8 m, aiming to pass the ball through a target consisting of two cones 1 m apart and 0.5 m high. Students’ successful passes constituted their score in the test.
2.3.2. Estimation of Soccer-Pass Performance
Just before performing the soccer-pass test, students estimated their soccer-pass performance by answering the following question: “How many passes out of 10 will you pass through the cones from this position?”
2.3.3. Calibration Bias and Accuracy
The calibration accuracy index was computed for each student by subtracting actual soccer-pass performance from estimated performance and taking the absolute value. This index represents the magnitude of calibration error. Scores closer to zero represent greater calibration accuracy (
Schraw, 2009). Calibration bias (i.e., the signed difference between estimated and actual performance) reflects the direction of calibration, but is not a linear indicator of accuracy. Therefore, it is not considered an appropriate measure for group mean comparisons (
Griffin et al., 2013) or correlational analyses (
Stankov et al., 2012). Therefore, calibration bias scores were used to classify students as accurate (score = zero), overestimators (positive scores), or underestimators (negative scores), indicating the direction of calibration.
2.3.4. Executive Functions
The design fluency test, including three conditions measuring design fluency, inhibition, and cognitive flexibility, was used (
Delis et al., 2001). The first condition of the test contains the core aspects of the design fluency skill, including working memory and creativity, whereas the second condition introduces an additional requirement for inhibiting automatic responses, and the third condition further incorporates demands on cognitive flexibility (
Vestberg et al., 2020). In each condition, students had to draw, within 1 min, as many original designs as possible by linking dots with four sequential straight lines. The response sheet in each condition included 35 square boxes, each displaying an unstructured array of dots. In the first condition (i.e., design fluency), students were required to connect dots in boxes that contained five solid dots. In the second (i.e., inhibition) and third (i.e., cognitive flexibility) conditions, boxes contained five blank and five solid dots each, and students were required to connect only blank dots (condition 2) or to alternate between blank and solid dots, starting either from a blank or a solid dot (condition 3). Before completing each condition, students were instructed on how to perform the task, observed their physical education teacher demonstrate the test on the blackboard of the classroom, and then completed three boxes of dots as a trial. Students’ scores in each test condition reflected the number of correct, non-repetitive designs they produced. This test has been widely used to examine students’ executive functions in the fields of school physical education (e.g.,
Kolovelonis & Goudas, 2023) and sport (e.g.,
Vestberg et al., 2012,
2020).
2.4. Procedures
The University Ethics Review Committee and the local Directorate of Primary Education approved the design and the procedures of this study. The principals and the physical educators of each school provided their consent for conducting the study in their schools, while parental written consent was obtained for each student’s participation. Students participated in the study voluntarily, and their personal information was kept confidential. The physical education teachers from the three schools (i.e., three teachers, all male, with teaching experience ranging from 25 to 30 years) implemented the soccer sessions for all experimental groups during regular physical education hours in the schoolyards. In each school, the physical education teacher delivered the soccer session using a specific teaching style. Additionally, a fourth physical education teacher delivered a session on the ancient Olympic Games to the control-group students, which took place in their classroom. Before the implementation of the sessions, the physical education teachers were trained to deliver the lesson plan with the respective teaching style. The content and the teaching procedures for all experimental groups were described in detail in written lesson plans. These lesson plans were piloted in classes of students not involved in the main study. After the implementation of the session, the physical education teachers completed a record sheet including specific criteria reflecting the fidelity of the intervention. They recorded whether each activity in the session was delivered as planned and described in the written lesson plan, within the predefined time, and whether the principles of the respective teaching style were followed (e.g., whether students in the self-check style used their task sheets to record their performance). Based on these records, the session was delivered to each experimental group, as planned. One week before the field experiment, students were pre-tested on estimation of soccer-pass performance, soccer-pass performance, and the design fluency test. After the implementation of the soccer session, students were post-tested on the same variables, following the same procedures. Similar procedures were followed for the control-group students. During the week before the post-test, students of all groups had similar physical education experiences.
2.5. Description of the Experimental Conditions
The content of the soccer session was identical for all experimental groups. What was different was the teaching style used to deliver this content to the three experimental groups (see details below). The aim of the session was to help students learn to perform correctly the following three basic key points of the soccer-pass technique: (a) “put the support foot slightly bent next to the ball”, (b) “the toe of the support foot points in the direction of the pass”, and (c) “pass the ball with the inside of the foot”, and to increase their passing accuracy (
Lennox et al., 2006).
The first part of the session included an 8 min organization and warm-up period. The second part of the session lasted 25 min and began with the physical education teacher providing students with oral instructions and a demonstration of the correct technique of the soccer pass (1 min). Next, students, in dyads, performed drills focusing on properly executing the technique of the pass (3 drills of 5 min each) and on increasing their accuracy in passing (3 drills of 3 min each). For example, in the first drill focusing on improving pass technique, students in dyads, at a 4–6 m distance, performed passes using a stationary ball placed on the ground. To increase their passing accuracy, students performed passes from a 4–6 m distance, aiming to pass the ball between two cones 1 m apart. The last part of the session included a modified small-scale soccer game (10 min) and a closing reflection and evaluation period (2 min) (
R. Ellis, 2021;
Lennox et al., 2006).
Students in the self-check style (Group 1) performed independently the drills described above, following instructions included in a task sheet provided by the physical education teacher. The sheet included the three basic key points of the technique of the soccer pass, a picture to illustrate these key points, an appropriate place for recording performance, and instructions on how to do it. By monitoring, recording, and comparing their performance against the performance standards described in the task sheet, students provided themselves with feedback to improve the technique and the accuracy of the soccer pass. During practice, the teacher provided students with feedback related to the appropriate use of the self-check style, if necessary. Students in the command style (Group 2) practiced the drills described above, following their physical education teacher’s instructions and cues, trying to perform the soccer pass correctly (in the first three drills) and accurately (in the last three drills). After the end of each drill, students received feedback from their teacher regarding their pass technique and accuracy. Students in the practice style (Group 3) performed the soccer drills presented by their teacher, selecting the location of their practice, the time devoted to each drill, and when to increase the distance from which they performed the pass. During practice, students received individual feedback from their teacher regarding their technique and accuracy in the soccer pass. Group-4 students (the control group) attended, in their classroom, a session regarding the ancient Olympic Games. This was a classroom-based, non-physical-activity control group, and it differed from the experimental groups in physical activity, instructional context, and arousal level. Therefore, it should be viewed as a reference condition, and comparisons with the experimental groups cannot be interpreted as reflecting teaching-style differences.
2.6. Statistical Analysis
Prior to analysis, the data were examined for accuracy of data entry, missing values, distributional fit, and univariate and multivariate outliers. To check for potential classroom nesting effects, unconditional linear mixed models were conducted for each post-test variable, to calculate Intraclass Correlation Coefficients (ICCs) [and Design Effects]. Because individual-level analyses were deemed appropriate, baseline differences between the four groups were examined with a one-way MANOVA for the design-fluency test conditions and with one-way ANOVAs for calibration accuracy and soccer performance. Differences among groups over time for the three conditions of the design fluency test were examined with a 4 (Group) × 2 (Time) repeated-measures MANOVA. Univariate tests, separate for each test condition, and comparisons between pre-test and post-test within each group, followed. Because baseline differences in calibration accuracy were observed among the four groups, group differences in post-test calibration accuracy were examined using a one-way ANCOVA, with Group as the factor, post-test calibration accuracy as the dependent variable, and pre-test calibration accuracy as the covariate. ANCOVA was selected to statistically adjust for baseline differences in calibration accuracy when examining group differences at post-test. Changes in soccer-pass performance across groups and time were tested with a 4 (Group) × 2 (Time) repeated-measures ANOVA, and comparisons between pre-test and post-test within each group were subsequently conducted. For all analyses and comparisons, the alpha level was set at 0.05. For estimating the size of the effects, the partial η
2 and Cohen’s
d were calculated (
Cohen, 1988).
3. Results
3.1. Preliminary Analysis
Table 1 presents the means and standard deviations of students’ pre- and post-test scores for all dependent variables, separately, for the four groups of the study. Applying the criterion that kurtosis and skewness values divided by their standard errors should fall within ±1.96 to indicate normality (
Field, 2024), almost all data for the dependent variables met the assumption of normal distribution. Some small deviations in skewness were found in the pre-test data regarding the estimation of soccer-pass performance in Group 1, in the first condition of the design fluency test (i.e., fluency) in Group 3, and in the post-test data for the second condition of the design fluency test (i.e., inhibition) in Group 4.
Preliminary cluster analysis using unconditional linear mixed models across the eight distinct classroom clusters (average cluster size = 18.38) revealed negligible nesting effects for the primary motor-performance and cognitive outcomes. Specifically, the intraclass correlation coefficients (ICCs) and corresponding design effects (Deff) were completely non-existent for soccer-pass performance (ICC = 0.000, Deff = 1.00) and inhibition (ICC = 0.000, Deff = 1.00), and exceptionally low for design fluency (ICC = 0.007, Deff = 1.12), and cognitive flexibility (ICC = 0.019, Deff = 1.33). In contrast, strong clustering occurred within the calibration accuracy measure, meaning classmates shared similar tendencies in performance calibration accuracy (ICC = 0.231, Deff = 5.01). Thus, the interpretation of the corresponding inferential tests for this variable should be approached with caution. A conditional random-intercept LMM was performed as a sensitivity analysis. However, the model failed to converge. The Hessian matrix was not positive definite, and the classroom intercept variance was zero, reflecting the sparse cluster structure. Despite this structural instability, the Group main effect remained statistically significant, F (3, 143) = 2.70, p = .048, with marginal R2 = 0.036, conditional R2 = 0.357, and an adjusted ICC of 0.333. This finding indicates that the descriptive trends across the instructional conditions reflect genuine raw data patterns, rather than artifacts of a single outlier classroom. The limited cluster structure (four schools, eight classes) is mathematically insufficient for stable multilevel estimation. Accordingly, these mixed-model indices should be interpreted with caution, supporting the adoption of individual-level analyses within an exploratory framework.
Baseline differences between the four study groups were examined for all dependent variables. The one-way MANOVA showed nonsignificant group differences in the three conditions of the design fluency test, F (9, 429) = 1.84, p = .06. Moreover, the one-way ANOVA showed significant differences between groups in the calibration accuracy, F (3, 143) = 4.02, p = .009, partial η2 = 0.078, and nonsignificant differences in the soccer-pass performance, F (3, 143) = 2.12, p = .10.
3.2. Group Differences in Inhibition and Cognitive Flexibility
Differences among the four groups in the three conditions of the design fluency test were examined with a 4 (Group) × 2 (Time) MANOVA. Multivariate outliers were assessed by calculating Mahalanobis distance values (
Fidell & Tabachnick, 2003;
Tabachnick & Fidell, 2019) and comparing them with the critical chi-square value at
p < .001 with 6 degrees of freedom (corresponding to the six variables derived from the three design-fluency test conditions measured at pre-test and post-test), which was 22.46. No cases exceeded this criterion, indicating the absence of extreme multivariate outliers. Homogeneity of covariance matrices were tested with Box’s M test,
M = 101.12,
F (63, 45,880.78) = 1.48,
p = .008. Considering that the sample sizes of four groups were unequal and the Box’s M test was nonsignificant at
p < .001 (
Tabachnick & Fidell, 2019), Pillai’s Trace was used as a more robust multivariate test (
Field, 2024;
Tabachnick & Fidell, 2019).
The 4 (Group) × 2 (Time) MANOVA with repeated measures showed a significant multivariate interaction for Group and Time (Pillai’s Trace = 0.174, F (9, 429) = 2.94, p = .002, partial η2 = 0.058) on students’ scores in the three conditions of the design fluency test (i.e., fluency, inhibition, and cognitive flexibility). Separately, for each test condition, repeated measures ANOVAs were followed. For condition 1 (i.e., fluency) a nonsignificant Group and Time interaction, F (3, 143) = 1.78, p = .15, but a main effect for Time, F (1, 143) = 34.19, p < .001, partial η2 = 0.19, were found. Significant Group and Time interactions were found for condition 2 (i.e., inhibition), F (3, 143) = 5.76, p < .001, partial η2 = 0.11, and condition 3 (i.e., cognitive flexibility), F (3, 143) = 4.37, p = .006, partial η2 = 0.08. Next, comparisons within groups were conducted, separately for the three conditions of the test, to check for differences between pre-test and post-test. In test condition 1 (i.e., fluency), significant pre-test-to-post-test improvements were found for Group 1 (self-check style), t (37) = 4.24, p < .001, d = 0.57, Group 2 (command style), t (33) = 3.17, p = .003, d = 0.37, and Group 3 (practice style), t (33) = 3.61, p < .001, d = 0.56, but not for Group 4 (control group), t (40) = 1.04, p = .30. In the second condition of the test (i.e., inhibition), significant pre-test-to-post-test improvements were found for Group 1 (self-check style), t (37) = 4.19, p < .001, d = 0.57, but not for Group 2 (command style), t (33) = 1.64, p = .11, Group 3 (practice style), t (33) = 1.66, p = .10, and Group 4 (control group), t (40) = −0.70, p = .49. In test-condition 3 (i.e., cognitive flexibility), significant improvements from pre-test to post-test were found for Group 1 (self-check style), t (37) = 3.54, p = .002, d = 0.40, and Group 3 (practice style), t (33) = 2.11, p = .043, d = 0.28, but not for Group 2 (command style), t (33) = 0.21, p = .83, and Group 4 (control group), t (40) = −1.34, p = .19.
3.3. Group Differences in Performance Calibration
Differences among the four groups in performance calibration were examined using a one-way ANCOVA to account for baseline difference between groups. The assumption of homogeneity of regression slopes was satisfied, as the interaction between the covariate (i.e., pre-test scores in calibration accuracy) and the independent variable (i.e., group) was nonsignificant F (3, 139) = 1.66, p = .178. After adjusting for the differences between groups in the calibration accuracy in pre-test, F (1, 142) = 5.39, p = .022, partial η2 = 0.037, the one-way ANCOVA, with Group as the factor, post-test calibration accuracy as the dependent variable, and pre-test calibration accuracy as the covariate, showed nonsignificant differences between groups in post-test calibration accuracy, F (3, 142) = 1.69, p = .172. The adjusted mean scores for calibration accuracy, along with the corresponding 95% confidence intervals (CIs), were 1.68 (95% CIs [1.16, 2.18]) for Group 1 (self-check), 2.21 (95% CIs [1.66, 2.76]) for Group 2 (command style), 2.10 (95% CIs [1.57, 2.64]) for Group 3 (practice style), and 1.48 (95% CIs [0.99, 1.97]) for Group 4 (control group).
Regarding the direction of calibration, the frequencies of accurate students, overestimators, and underestimators in all study groups at the pre-test and post-test are presented in
Table 2. Overall, the frequency distributions suggested that, regardless of group, most students did not accurately estimate their soccer performance. Indeed, in the total sample, the percentage of students who accurately estimated their soccer performance was only 15% (22 students) on pre-test and 20% (29 students) on post-test. In contrast, 34% of the students (50 students, both at the pre-test and the post-test) estimated that their soccer performance would be lower than it actually was, whereas 75 students (51%) at pre-test and 68 students (46%) at the post-test estimated that their soccer performance would be higher than it actually was. Small variations in these frequencies from pre-test to post-test were also observed in almost all calibration-bias categories across the study groups. The frequency of accurate students remained stable in the self-check-style group, increased in the command-style and control groups, and decreased in the practice-style group. Overestimators decreased in the self-check style and control groups, remained unchanged in the practice-style group, and increased in the command-style group. Underestimators increased in the self-check style, practice-style, and control groups, but decreased in the command-style group. These data were not subjected to inferential statistical analyses because the primary analyses focused on the continuous measure of calibration accuracy, whereas the categorical classifications based on students’ bias scores were used solely for descriptive purposes. Given the relatively small number of cases in some categories, these patterns should be interpreted cautiously and considered descriptive in nature.
3.4. Group Differences in Soccer-Pass Performance
The 4 (Group) × 2 (Time) ANOVA with repeated measures and students’ score in the soccer pass performance as dependent variable showed a nonsignificant interaction for Group and Time, F (3, 143) = 1.72, p = .17, but a significant main effect for Time, F (1, 143) = 10.66, p < .001, partial η2 = 0.07. Within groups comparisons revealed significant improvement in soccer-pass performance from pre-test to post-test for Group 1 (self-check style), t (37) = 3.02, p = .005, d = 0.38. Nonsignificant improvements from pre-test to post-test were found in Group 2 (command style), t (33) = −0.33, p = .74, Group 3 (practice style), t (33) = 1.88, p = .07, and Group 4 (control group), t (40) = 1.82, p = .08.
4. Discussion
This study explored students’ cognitive (i.e., inhibition and cognitive flexibility), metacognitive (i.e., calibration accuracy), and motor (i.e., soccer performance) responses under different Spectrum teaching styles in physical education. Three groups of students were taught the soccer pass using a different teaching style (i.e., self-check, command, and practice style) during a single physical education session, whereas a control group of students who were taught a classroom-based session on the ancient Olympic Games were also involved. Students in the self-check group demonstrated greater improvements in inhibition and cognitive flexibility from pre-test to post-test than students in the command and practice groups. In addition, students in the practice group showed improvements in cognitive flexibility over time. The three experimental groups showed within-group improvements in design fluency. However, the interaction was nonsignificant, and thus this study cannot demonstrate significant differences among teaching styles regarding relative gains in design fluency. No differences between groups were found in calibration accuracy. Regarding soccer-pass performance, pre- to post-test improvements were found in the group of students who were taught the soccer pass with the self-check teaching style, without, however, outperforming the students of the other groups. Nonsignificant changes in all variables were found for the control group. Next, these findings are discussed in detail, drawing on prior empirical research and considering their theoretical and practical implications for the use of different teaching styles in physical education.
4.1. Inhibition and Cognitive Flexibility Under Different Teaching Styles
Students in the self-check group demonstrated greater improvements in inhibition and cognitive flexibility than students in the command and practice groups. Although the exploratory nature of the study precludes causal conclusions, this pattern of findings is consistent with our expectation that the self-check style may be associated with more favorable executive-function responses. The self-check style shifts responsibility for evaluation and decision-making from teachers to learners, enabling students to work independently to master skills, monitoring and checking their own performance against specific performance criteria (
Byra, 2000;
Mosston & Ashworth, 2008). Using the self-check style, students were involved in goal setting, monitoring, and reflection, adjusting their actions and strategies, if necessary, processes that are appropriate for strengthening cognitive flexibility and adaptive strategy shifting. During practice, students paused regularly to evaluate their performance, which likely inhibited automatic responses and suppressed impulsive execution in favor of deliberate monitoring, recording, and assessment, thereby activating inhibitory-control mechanisms (
Diamond, 2013). Indeed, it has been found that goal setting and self-recording of performance increased students’ inhibition and cognitive flexibility more than simply practicing with feedback from the teacher (
Samara et al., 2023), whereas reflective thinking and practice were associated with enhanced cognitive flexibility (
Orakcı, 2021). However, all these proposed mechanisms should be directly examined and verified in future research.
Interestingly, students in the practice-style group demonstrated significant improvements in cognitive flexibility from pre-test to post-test. The practice style provides students with opportunities to be involved in making decisions regarding various aspects of the practice such as the pace and rhythm of practice, the start and stop times for each task, and the intervals between tasks (
Byra, 2000,
2018). This partial decision-making responsibility requires students to monitor their practice, to avoid distractions, make adjustments, and shift strategies as needed, processes that are associated with students’ cognitive flexibility (
Diamond, 2014;
Diamond & Ling, 2020). In contrast, no significant changes in inhibition or cognitive flexibility were observed in the command-style group. Students in the command style had to follow their teacher’s cues and instructions, trying to reproduce the soccer-pass skills and activities as accurately as possible (
Byra et al., 2014). The teacher made all instructional decisions, while students simply reproduced prescribed movements or responses with minimal decision-making, problem-solving, or cognitive engagement, thus limiting the potential to influence their executive functions (
Diamond, 2013;
Diamond & Lee, 2011).
Students in all experimental groups improved their scores on the first condition of the design fluency test. Since no differences emerged among the experimental groups, this improvement cannot be linked to a specific teaching style. Rather, the improvement may have resulted from participation in the soccer session itself. Indeed, control-group students who attended a classroom-based lesson on the history of the ancient Olympic Games did not demonstrate any improvement in the design fluency test. Nevertheless, the potential influence of task-familiarity and practice effects cannot be entirely excluded, given that the same measures were administered at pre-test and post-test. Although the absence of improvement in the control group suggests that repeated testing was unlikely to be the primary driver of the observed gains, the control condition differed from the experimental groups in terms of setting, arousal, and task context. The first condition of the test measures design fluency, requiring students to generate as many unique designs as possible. In doing so, they must use working memory to keep track of their previous responses and avoid repeating them. Thus, working memory and creativity are involved in the first condition of the design fluency test (
Vestberg et al., 2020). Moreover, the capacity to generate novel designs has been found to rely primarily on motor planning, that is, the ability to produce novel motor actions (
Suchy et al., 2010). Indeed, positive associations between physical activity and working memory (
Russo et al., 2021) and creativity (
Bollimbala et al., 2021) have been reported. However, these interpretations were not directly tested in the present study, and therefore they should be further explored and verified in future research.
This is the first study, to our knowledge, which explored students’ executive-function responses (i.e., inhibition and cognitive flexibility) under selected Spectrum teaching styles. Previous studies in physical education have focused on the content of the physical activity programs, showing that cognitively enriched physical-activity programs enhanced students’ executive functions (e.g.,
Kolovelonis & Goudas, 2023). This study extends previous research by suggesting that students in the self-check group, and, to a lesser extent, those in the practice group, demonstrated more favorable inhibition and cognitive flexibility responses than students in the other groups. These findings provide preliminary support for the hypothesis that some teaching methods may create challenging learning environments that are more conducive to students’ mental engagement during physical education lessons (
Pesce et al., 2016;
Vazou et al., 2019). Evidence from a similar line of research has also suggested that using the varied linear pedagogy approach that involved teaching with a reproductive teaching approach, reflected in the “self-check” and “reciprocal” styles, improved students’ inhibitory control (
Invernizzi et al., 2022).
4.2. Performance Calibration Under Different Teaching Styles
Contrary to our hypothesis, no differences between groups were found in students’ calibration accuracy regarding soccer performance. Generally, students in this study, regardless of the group, did not accurately estimate their performance. The presence of this overestimation is consistent with previous empirical findings in school physical education suggesting that students usually overestimate their performance in various sports skills, including basketball dribbling, chest pass, and shooting, and soccer-pass (
Kolovelonis & Goudas, 2012). Previous evidence also suggested that students who were taught with the reciprocal or the self-check style did not differ in calibration accuracy, but those who received more-accurate feedback during their practice with one of these styles outperformed those who received less-accurate feedback (
Kolovelonis & Goudas, 2012). In this study, it was expected that involving students in goal setting, monitoring, and recording performance (e.g., during practice with the self-check style) would increase their awareness of learning and performance and enhance their calibration accuracy (
D. Ellis & Zimmerman, 2001;
Hadwin & Webster, 2013). However, this hypothesis was not confirmed. The single physical education session was not sufficient to meaningfully shift students’ calibration accuracy. Probably, improvements in calibration accuracy may need more time to occur and require multi-component interventions (
Digiacomo & Chen, 2016;
Gutierrez de Blume, 2022). Indeed, it has been found that an appropriately designed intervention, including not only goal setting and self-monitoring, but also self-talk, self-evaluation, self-reflection on performance, and causal attributions can help students increase the accuracy of their performance estimations (
Kolovelonis et al., 2022). Moreover, baseline differences in calibration accuracy were observed, with students in the self-check style showing lower scores (indicating higher accuracy) compared to the other groups, which made further improvements more difficult.
4.3. Soccer Performance Under Different Teaching Styles
Students in the self-check-style group demonstrated a significant improvement in soccer-pass performance from pre-test to post-test. However, this within-group improvement did not translate into superior performance relative to the other groups, as nonsignificant between-group differences were observed. No significant pre-test-to-post-test improvements were found in the command- and practice-style groups. Previous findings have shown that the self-check style had positive effects on students’ sports performance. Indeed, students who practiced with the self-check style significantly improved their performance in a variety of sports skills, including basketball chest pass (
Digelidis et al., 2018;
Kolovelonis et al., 2011), basketball dribbling and jump shot (
Digelidis et al., 2018), tennis skills (
Patmanoglou et al., 2008), and folk dances (
Pitsi et al., 2023). Moreover, the self-check style, compared to the command style, has been found to be more effective for university students to learn Greek folk dances (
Pitsi et al., 2023). The self-check style involves students in goal setting and self-monitoring of their performance, processes that have been found to be effective in improving students’ motor and sports performance and in promoting self-regulated learning in physical education (
Kolovelonis et al., 2022).
4.4. Practical Implications
From an applied perspective, the Spectrum of Teaching Styles offers physical education teachers a rich repertoire of teaching styles designed to help students achieve diverse learning objectives across multiple domains (
Mosston & Ashworth, 2008). Each style focuses on distinct objectives and creates a unique instructional environment, enabling educators to shape learning experiences that best align with desired outcomes. Consequently, physical educators can select the most appropriate style by considering the specific characteristics of their students, the goals they wish to pursue, and the unique conditions of the teaching context, such as limited time, space, or available resources (
Goldberger et al., 2012). Given that school physical education seeks to promote not only psychomotor, but also cognitive and social development, relying on a single instructional approach may be insufficient. Instead, employing the most appropriate teaching styles can more effectively address these multiple aims, facilitating a wide range of learning and performance outcomes despite the constraints often present in school settings (
Garn & Byra, 2002).
The findings of this study suggest that the self-check style may be associated with more favorable responses in inhibition, cognitive flexibility, and soccer performance under the instructional conditions examined. This evidence may encourage physical educators to incorporate not only the command and practice styles (
Chatoupis, 2018;
Kulinna & Cothran, 2003), but also a broader range of teaching styles into their instructional repertoire. For example, by using the self-check style for teaching sports skills, physical educators can enhance both the psychomotor and cognitive aspects of their students’ learning and performance. The self-check style is also appropriate for involving students in self-regulated learning. Indeed, through the self-check style, students set learning and performance goals, monitor and evaluate their progress against performance standards, and improve their performance (
Kolovelonis et al., 2022).
4.5. Limitations and Future Research
The study’s limitations should be acknowledged. For example, the intervention consisted of only a single session; therefore, the findings should be interpreted as reflecting students’ immediate responses under different instructional conditions, rather than long-term learning outcomes. These acute responses offer useful insight but do not necessarily indicate lasting cognitive, metacognitive, or motor changes. To determine whether these observed patterns persist or accumulate over time, future studies should use a longitudinal design involving multiple sessions and retention measures. In addition, this study involved only one sport skill (i.e., soccer pass), which was taught to students during a single physical education session. Future research may examine the effects of interventions with a larger number of sessions and a variety of sport and motor skills. Moreover, soccer performance was measured with a single test measuring the precision of students’ pass execution. Future research may focus on multiple indicators of sports performance, including technical aspects of motor- and sports-skills performance. Similarly, executive functions were measured with a single test (i.e., the design fluency test). The advantage of this test is that it can be easily and quickly administered at the class level. Future studies would benefit from employing multiple assessments to evaluate executive function. Another important limitation related to the study’s internal validity was that the fidelity of intervention implementation was based solely on teachers’ self-reported data recorded immediately after the intervention, and was not independently verified. Future research should also involve fidelity checks using external raters to ensure that the interventions are implemented as they are planned.
A further limitation is that students were nested within eight classes and clustering effects (assessed via ICCs) were negligible for most outcomes but more pronounced for calibration-related measures, suggesting that standard errors for these variables may be somewhat underestimated. This represents a major limitation in the interpretation of the calibration accuracy results. Moreover, with only eight classes, the available cluster structure was insufficient for reliable estimation, and more complex multilevel modeling was not feasible. Consequently, the inferential results should be considered exploratory and interpreted with caution. To assess the robustness of the findings, a post hoc conditional random-intercept LMM sensitivity analysis was performed. The analysis confirmed that the cluster structure (four schools and eight classes) was too sparse to support stable multilevel estimation, resulting in a non-positive definite Hessian-matrix warning and redundant classroom-level variance parameters. Except for the statistical instability introduced by sparse clusters, three contextual considerations justify the use of an individual-level analytic frame. First, preliminary checks showed that classroom-level nesting was negligible for the motor and cognitive outcomes central to our conclusions, becoming meaningful only for calibration accuracy, a variable for which no group differences emerged. Second, variation in teacher involvement across conditions is an inherent feature of
Mosston and Ashworth’s (
2008) framework, which defines teaching styles by who makes the decisions. Third, any potential teacher variation was minimized through standardized, pre-piloted lesson plans, which ensured identical content, activities, and timing across all groups. Furthermore, statistical analysis focused on the individual level rather than the group level, as the aim of the study was to explore students’ cognitive and behavioral responses under different instructional conditions. To enhance the ecological validity of the study, given that students are taught in intact classes at school, randomization was conducted first at the school level and then at the grade level. However, this design may have increased the risk that school-level factors influenced the findings, thereby representing a major threat to internal validity. Nevertheless, as a field-based study conducted under authentic physical education conditions, the design aimed to balance methodological control with ecological validity. The elementary schools involved in this study shared similar characteristics (e.g., number of students and classes, sport facilities, and teachers with similar teaching experiences), reducing, although not eliminating, the likelihood of substantial school-level differences. Furthermore, randomization at the school level prevented contamination between experimental conditions and avoided having the same teachers teach groups assigned to different teaching styles. In addition, all participating teachers had comparable teaching experience and received training in the implementation of the assigned teaching style prior to data collection.
Further research should examine the link between teaching styles and executive functions. This study focused on three teaching styles for teaching a soccer-passing skill, with all groups receiving identical session content except for the instructional approach. Considering, however, that the nature and the characteristics of the content of a physical activity program (cognitively enriched or not) play an important role in enhancing students’ executive functions (e.g.,
Kolovelonis & Goudas, 2023), the interplay between teaching styles and the type of content delivered through each style, with respect to their effects on students’ executive functions, warrants further investigation. Future research should also examine the effects of additional teaching styles on students’ executive functions, particularly through comparisons across the broader clusters of the Spectrum (direct styles, student-assessment styles, discovery styles, and student-initiated styles;
Syrmpas et al., 2020). Motivational variables may also be involved in this research. These could include examining how different teaching styles influence students’ self-efficacy, enjoyment, or situational interest, given that these constructs play a central role in students’ engagement and learning processes. Such evidence would not only enrich our understanding of the motivational pathways activated by each teaching style, but also help clarify how these motivational responses interact with students’ cognitive, metacognitive, and psychomotor development.
