Abstract

This study analyses the effectiveness of a contextualized teaching and learning sequence (TLS) based on forensic entomology (FE) to disprove the idea of spontaneous generation (SG) among students enrolled in the Higher Vocational Education and Training (VET) Cycle in Pathological Anatomy and Cytodiagnosis. Through an inquiry- and project-based learning approach, students replicate a version of Francesco Redi’s historical experiments, enabling them to engage with core scientific concepts such as the metamorphic cycle of insects and the role of entomology in forensic science. The research adopts a semiquantitative and exploratory design. It investigates: (1) whether students’ prior knowledge about FE and related biological processes is sufficient to refute SG; (2) to what extent this knowledge is influenced by their previous academic background and gender; and (3) whether a contextualized TLS can significantly enhance their conceptual understanding. The results reveal that most students begin with limited initial knowledge of FE and multiple misconceptions related to SG, irrespective of their previous study. Gender differences were observed at baseline, with women showing lower prior knowledge, but these differences disappeared after the intervention. The post-intervention data demonstrate a significant improvement in student’s ability to reject SG and explain biological processes coherently. The study highlights the importance of integrating entomology into health-related VET programs, both as a means to promote scientific literacy and correct misconceptions and as a pedagogical tool to foster critical thinking. It also highlights the potential and historically grounded methodologies to equalize learning outcomes and strengthen the scientific preparation of future healthcare professionals.

1. Introduction

The history of science provides numerous examples of how highly creative and imaginative individuals have achieved significant scientific milestones (Dogan et al., 2020). However, foundational knowledge and interdisciplinary approaches have played a crucial role in shaping such creative solutions. One notable example is the Italian physician, biologist, linguist, and poet Francesco Redi (1626–1697), who was the first to refute the historical belief in spontaneous generation (SG) at the macroscopic level. As a scholar of the classics, Redi had read Homer’s Iliad, which recounts Achilles’ fear that flies might enter the wounds of Patroclus’ corpse, producing maggots and defiling his lifeless body (Kotsias, 2002). Inspired by this passage from Book XIX of the Iliad, Redi questioned the origin of maggots in corpses and designed experiments to disprove SG (Jiménez Martínez, 2021). Through his work, detailed in Esperienze intorno alla generazione degl’insetti (Redi, 1668), he demonstrated that maggots (larvae) originated from fly eggs rather than decaying flesh, laying the foundation for rigorous scientific methodology. Later, scientists such as Lazzaro Spallanzani (1729–1799) and Louis Pasteur (1822–1895) extended this work to the microscopic level, with Pasteur ultimately providing definitive evidence against SG (Curtis et al., 2008). These pivotal experiments illustrate how empirical evidence and scientific rigor have been instrumental in overturning long-standing beliefs on SG and advancing scientific knowledge (Hejran et al., 2024).

1.1. Students’ Misconceptions About Spontaneous Generation

Despite advances in science since Redi and Pasteur’s experiments, ideas compatible with SG still persist among students and pre-service teachers. These misconceptions—broadly defined as student-held conceptions inconsistent with scientific knowledge (Yip, 1998)—resemble those once used to explain the origin of life centuries ago.
For instance, Vijapurkar and Konde (2014) identified similar misconceptions among middle school students in India, who reported the sudden appearance of life forms observed in their daily experience. These authors described a wide range of ideas among these students, including pre-Pasteur notions suggesting that certain forms of life arise spontaneously from inorganic matter. Likewise, Samarapungavan and Wiers (1997) found that 14.3% of students aged 8 to 13 in their study believed that species originate through SG from plant matter or soil. Similarly, Núñez Acosta et al. (2013) observed that pre-service students of the Primary Education degree struggled to predict primary ecological successions, particularly in scenarios involving the origin of vegetation—thus revealing persistent misconceptions when explaining the emergence of certain plants. Stahl (1992, p. 6) also reported folkloric beliefs among Israeli fifth-grade students, such us “Lice are created in people’s hats when very hot winds are blowing”.
The persistence of these misconceptions may be attributed to multiple factors, including everyday experiences that reinforce erroneous ideas, the language used in daily communications, conceptual errors in teaching materials, superficial topic coverage, inadequate classroom methodologies, and the prevalence of similar misconceptions among students and teachers (Ault, 1984; Badenhorst et al., 2015; King, 2009; Kumandaş et al., 2018; Larkin, 2012). Additional influences include the attribution of validity to popular but incorrect knowledge and the impact of mass media (Carrascosa-Alís, 2005, 2014; Stahl, 1992). These factors pose significant challenges for science education, particularly in today’s post-truth era, where misinformation spreads rapidly through mass media and social networks (Molina et al., 2021).
Such misconceptions often become deeply embedded within students’ cognitive frameworks, making them resistant to change even when confronted with structured and explicit instruction. This not only hinders the acquisition of new knowledge, but may also negatively affect students’ attitudes toward science, reducing both their interest and motivation (Guerra-Reyes et al., 2024). Therefore, identifying and addressing these misconceptions is a prerequisite for achieving meaningful conceptual, procedural and attitudinal changes.
For conceptual change to occur, students must first recognize inconsistencies between their prior knowledge and scientifically validated explanations. This process of cognitive conflict, followed by reflection, is what allows the replacement of erroneous or inaccurate ideas with scientifically sound ones (Driver, 1986, 1988; Treagust & Duit, 2008). Conceptual change requires learners to become dissatisfied with their preconceptions when confronted with evidence that contradicts them (Posner et al., 1982). However, this process is neither immediate nor spontaneous; it requires time, guided instruction, and carefully designed learning situations. Given that the same everyday observations that once supported belief in SG still occur today, these misconceptions are likely to persist unless they are explicitly and systematically addressed in educational settings.
It is also important to recognize that the persistence of misconceptions is not solely dependent on student-related factors. Teacher training and pedagogical approaches play a central role in shaping students’ conceptual frameworks. The continued reliance on transmissive teaching models, the disconnection between school science and students’ lived experiences, a decontextualized curricular content, and insufficient development of inquiry skills, among others, contribute to the entrenchment of scientific misunderstandings (Guerra-Reyes et al., 2024). Considering this, equipping educators with effective teaching strategies to challenge and replace these misconceptions remains a necessary but complex task (Treagust & Duit, 2008).

1.2. Integrating the History of Science to Foster Scientific Literacy and Address Misconceptions

Incorporating history of science (HOS) in science instruction is a valuable resource for addressing alternative conceptions and fostering conceptual change in students (McComas, 2011; Solomon et al., 1992). Scientific controversies, such as the debate between Pasteur (as detractor) and Pouchet (as defender) on SG, enhance understanding of aspects related to the nature of science (NOS) (Abd-El-Khalick, 1999, 2013; Irwin, 2000; McComas et al., 2020) and contextualize how the scientific community faced the challenges of their research and how this contributed to the construction of scientific ideas (Acevedo-Díaz et al., 2016, 2018; McComas, 2011; Raynaud, 2017). This approach not only helps to dismantle misconceptions about SG (conceptual dimension) but also strengthens procedural (methodological) and attitudinal (axiological) dimensions (Aikenhead, 1985; Duschl & Gitomer, 1991; Solbes, 2009). In fact, HOS provides a solid foundation for NOS instruction (McComas et al., 2020), as effective NOS teaching requires both conceptual engagement and critical reflection on fundamental aspects of science itself. This is best achieved through didactic scenarios specifically designed to elicit such discussions (Abd-El-Khalick, 2013; Kruse et al., 2020). In this regard, content-embedded strategies have proven more effective in fostering a more accurate understanding (Allchin, 2011; Cofré et al., 2019).
Therefore, a practical way to integrate HOS into a contextualized science teaching is through active methodologies such as inquiry-based learning (IBL) (Urdanivia Alarcon et al., 2023; Yacoubian & BouJaoude, 2010). This approach allows students, starting from a question that triggers their interest, to formulate hypotheses based on their previous conceptions, design and conduct experiments to gather evidence that confirms or refutes these hypotheses, and interpret data and draw conclusions that they then communicate to the rest of the students (Melesse et al., 2025; Pedaste et al., 2015; Urdanivia Alarcon et al., 2023). In this way, they develop scientific skills such as argumentation and critical analysis of evidence (Strat et al., 2024). Moreover, when combined with project-based learning (PBL), this approach places students as the protagonists of their own learning, fostering their autonomy, critical thinking skills, and responsibility (Kokotsaki et al., 2016; Ngereja et al., 2020). Final projects, such as the creation of a scientific poster, allow students to provide a well-defined outcome to real-world problems, applying and consolidating knowledge in meaningful contexts (Sircar et al., 2024; Wallengren Lynch, 2017).
Therefore, recreating historical experiments in the classroom, such as those carried out by Francesco Redi, can engage students by confronting them with the same questions faced by scientists centuries ago (Alisir & Irez, 2020; Byington, 2001; Cobo et al., 2022). This reinforces the idea that science is a continuous process of questioning and investigation, where validation or refutation of ideas through the scientific method drives progress. Furthermore, Redi’s experiments align with scientific methodology without being sophisticated (Rama Espejo, 2018), making knowledge accessible to all students and respecting diversity and different levels of learning in the classroom (Custodio et al., 2015). Such experiences foster conceptual changes alongside methodological and attitudinal transformations (Gil & Carrascosa, 1985; Solbes, 2009).

1.3. Scientific Education and Curricular Gaps in Vocational Education and Training

The knowledge gained by recreating Redi’s experiment to refute SG is applicable to the current Spanish curriculum of Primary Education, Compulsory Secondary Education, and Baccalaureate (Royal Decree, 2022a, 2022b, 2022c). Therefore, teachers at these educational levels can identify a clear connection between the competencies established in legislation and their development through didactic experimentation. However, this connection is not as evident in Vocational Education and Training (VET), despite its practical approach, orientation towards employability, and emphasis on fostering autonomy (CEDEFOP, 2023).
At the curricular level, VET in Spain does not usually include scientific projects or activities in which students, through IBL, can experiment and test the empirical aspects of science. This absence makes the development of critical thinking more challenging in these contexts, as vocational training tends to focus primarily on technical skill acquisition rather than fostering analytical reasoning. However, studies indicate that lessons characterized by interactivity, dynamism, and active student participation not only facilitate the teacher’s work but also enhance the development of critical thinking, even in technical and vocational settings (López et al., 2023).
VET centers that, in addition to offering the Workplace Training module in external institutions, also provide intra-center training (Decree, 2022; Royal Decree, 2014), can implement their own training practices that bring research closer to students, addressing key scientific concepts. Incorporating methodologies such as IBL and PBL in these settings can strengthen students’ ability to evaluate evidence, engage in argumentation, and apply scientific reasoning to practical tasks, improving their overall preparation for professional environments.
This study focuses on VET, specifically on the Higher-Level Vocational Training Cycle in Pathological Anatomy and Cytodiagnosis (PAC), one of whose professional opportunities is that of Forensic Technician Assistant (Organic Law, 2003; Royal Decree, 2014). Technicians trained in this cycle are expected to possess the necessary skills to work in Institutes of Forensic Medicine and Forensic Sciences (Decree, 2022; Royal Decree, 2014). However, despite the rigorous training received, students often lack basic zoological knowledge, which is not addressed in the VET curriculum, as it is assumed to have been acquired in previous educational stages (Primary and Secondary Education). Consequently, although future technicians are expected to meet the competencies established in the Necropsy module (Royal Decree, 2014), the curriculum does not include specific content on Forensic Entomology (FE). This could explain why misconceptions related to SG may persist among these students. In this context, FE can only be effectively used to refute SG if teachers choose to incorporate this applied aspect of entomology into their teaching, either to extend or reinforce content and learning outcomes or to discuss and relate the origin of insects to their metamorphic cycle. By fostering active methodologies such as inquiry-based within VET programs, educators can provide students with the tools to critically evaluate scientific claims, reinforcing the importance of analytical reasoning in technical and vocational disciplines.

2. Objectives of the Study

Debunking misconceptions about SG in the general population is important, but it is crucial that they do not persist among students in the healthcare field, as these beliefs could impact their future health professional development. Given the relevance of FE and associated biological concepts in their field, it is imperative to assess and enhance these students’ understanding of SG through targeted educational interventions. In this context, strengthening scientific education in VET programs becomes even more essential.
Although numerous studies have explored misconceptions related to SG, most focus on secondary education or teacher training (see, for example, Vijapurkar & Konde, 2014). Research examining the persistence of such conceptions withing VET, especially in health-related fields, remains limited. This study seeks to fill these gaps by analyzing the impact of a contextualized teaching and learning sequence (TLS) in a Higher VET program, contributing conceptually, methodologically, and empirically to the development of science education in vocational settings. The contextualization in the TLS refers to the integration of diverse pedagogical approaches within the TLS, including the use of HOS, inquiry-based activities, and reflective practices, all of which have been shown to effectively promote a more accurate understanding of NOS (Cobo et al., 2022).
Building on these considerations, this study is guided by the following research questions:
  • Q1. Does the knowledge of these VET students about FE and associated concepts (arthropods, biological cycles, etc.) allow them to refute the existence of SG?
  • Q2. Is this knowledge influenced by their previous education and gender?
  • Q3. Does their understanding improve after participating in a contextualized TLS in which students experimentally reproduce a version of Redi’s experiments?
In response to these questions, the objectives of the study are: (i) to assess VET student’s prior knowledge of FE and associated biological concepts; (ii) to determine whether prior knowledge is influenced by student’s gender or educational background; (iii) to design and implement a contextualized TLS using Redi’s historical experiment as an inquiry-based activity; and (iv) to evaluate the effectiveness of this TLS in improving student’s understanding of SG and enhancing their NOS framework.
The working hypothesis of this study is that students’ initial knowledge of FE is generally limited, and consequently their ability to refute SG is weak, despite their studies being related to the healthcare field. This knowledge is expected to be independent of gender but influenced by their previous education and to improve significantly after engaging in a contextualized TLS, designed both to confront SG misconceptions and to enhance student NOS understanding.

3. Materials and Methods

3.1. Research Methodology and Participants

The study follows an exploratory mixed-methods design, combining qualitative data collection with semiquantitative analysis.
Participants are students enrolled in vocational training internships in the Higher VET cycle in PAC at Galeno—Xtart Centro Privado de Formación Profesional Sanitaria (VET Center in Valencia, Spain). Therefore, the sampling is non-probabilistic and based on convenience.
A total of 76 students participated over three academic years (2020–2021, 2021–2022 and 2022–2023). The intervention, based on an IBL approach and framed in a historical context (Redi’s experiment), included educator guidance and facilitated individual, small-group, and whole-class discussions.
Table 1 details the sociodemographic profile of the participants. Data from only those students who completed both the pre- and post-intervention questionnaires were analyzed. Participation in the questionnaires was voluntary, and students could withdraw at any time without consequences. To ensure privacy, we assigned numerical codes for reporting the findings.

3.2. Intervention

The contextualized TLS, titled ‘Redi 2.0’, aimed to address misconceptions about the historical scientific controversy of SG while teaching NOS. The intervention consisted of 18 face-to-face sessions, each lasting six hours, structured in four phases (Table 2). This format was integrated into the VET cycle’s curricular training activities.
During the intervention, students learned relevant historical events related to SG and were required to design and conduct a research project to refute SG. This hands-on investigation allowed them to explore entomology in general and FE in particular through an inquiry-based approach. Following the investigation, students presented their findings through a poster session, participated in a group discussion, assessed their self-perceived learning, and completed a post-intervention questionnaire to evaluate their understanding of FE and their ability to refute SG across all the proposed scenarios.

3.3. Instruments and Data Collection

The effectiveness of the TLS was assessed using a single questionnaire, administered twice (pre- and post-intervention), with minor verbal adaptations in the second application to acknowledge that the intervention had occurred (Table 3). The questionnaire contained five open-ended questions (Q1, Q2, Q3, Q4 and Q6) and one mixed-format question (Q5). The first two questions assessed students’ knowledge of FE and related organisms. The remaining four questions addressed students’ conceptions about SG and its connection to insects (and thus to FE) as well as other types of organisms.

3.4. Assessment Criteria and Scoring

To establish the assessment criteria, terms or concepts in each answer were grouped into blocks based on their conceptual relevance. Thus, each block contained a set of conceptually related terms that aligned with the expected level of response (Table A1).
Subsequently, student responses were analyzed based on the quantity and quality of relevant terms or concepts used and their presence in one or more blocks. A score of 0 was assigned when the answer did not meet the defined criteria: if it did not include any of the predefined terms, it was left blank, or the student indicated ‘I don’t know’. Scores of 1, 2, or 3 were assigned depending on the number of relevant blocks mentioned. For Q5, the same scoring criteria were applied, but without predefined blocks of terms. Table A2 details the rubric used for response analysis, specifying the evaluation criteria.

3.5. Data Analysis

Two independent raters scored each student’s response using the criteria indicated in Table A1 and Table A2. Cohen’s kappa (Cohen, 1968; Rau & Shih, 2021) was calculated to assess the degree of agreement between raters, using the cohen.kappa function (R psych package; Revelle, 2025). A low Cohen’s kappa would suggest a need for clearer scoring criteria, while a high value (κ > 0.8) indicates reliable and consistent assessments.
The Kaiser-Meyer-Olkin (KMO) measure (Kaiser, 1970; Ibikunle et al., 2021) was used to determine the adequacy of the sample for factor analysis, with values over 0.7 justifying its use. Bartlett’s test of sphericity (Bartlett, 1951; Tong, 2024) was applied to test the correlation between scores using the cortest.bartlett function (R psych package). A sedimentation plot (Del Giudice, 2022) was generated using the fa.parallel function (R psych package) to determine the number of underlying factors, and Cronbach’s alpha (Cronbach, 1951; Izah et al., 2024) was calculated to assess internal consistency using the alpha.cronbach function (ltm package; Rizopoulos, 2006).
Generalised Linear Mixed Models (GLMMs; Bolker, 2015) with a Gaussian distribution were applied using the glmmTMB function (R glmmTMB package, Brooks et al., 2017) to evaluate student learning throughout the intervention. The dependent variable was ‘Overall Knowledge,’ a single factor representing the sum of scores across all questions for each student, ranging from 0 to 18 (maximum score of three points on each of the six questions). Fixed effects (predictor variables) included the time of questionnaire completion (pre- and post-intervention), gender, previous education level (Intermediate VET, Higher VET, Baccalaureate or University), field of prior training (scientific or non-scientific), and relevant interactions. Random effects included the year of intervention, to account for potential interannual variability in course content or socio-political factors (e.g., the SARS-CoV-2 pandemic), and individual participant differences, to control for data dependence and inherent educational, psychological, or personal differences. The model with the lowest corrected Akaike Information Criterion (AICc; McQuarrie & Tsai, 1998) was selected using the dredge function (MuMIn package; Barton, 2020).
To examine the relationship between questionnaire scores and students’ self-perception of learning, a Generalized Additive Model (GAM; Hastie & Tibshirani, 1990) with a Gaussian distribution was applied. In this analysis, ’Overall Knowledge’ was the predictor variable, and students’ self-assessment (rated on a 0–10 scale) reflecting their perceived quality of learning was the response variable. The gam function (mgcv package; Wood, 2011) was used for this analysis. All analyses were conducted using R software v. 4.0.4 (R Core Team, 2021).

4. Results

4.1. Questionnaire Validity

The Cohen’s kappa values obtained for the six questions indicate high inter-rater reliability: 0.94 for Q1, 0.96 for Q2, 0.99 for Q3, 0.94 for Q4, 0.94 for Q5, and 0.98 for Q6. Therefore, it was not necessary to revise the scoring criteria. Furthermore, we obtained a Kaiser-Meyer-Olkin measure of sampling adequacy of 0.77 and a p-value < 0.001 in Bartlett’s test of sphericity. Cronbach’s alpha, with a value of 0.75, confirms the strong internal consistency of the questionnaire, thus validating its design.

4.2. Descriptive and Qualitative Analysis

Table 4 presents students’ responses to the questionnaires, categorized by gender, before and after the TLS. The results are expressed in absolute numbers and percentages according to the scores obtained.
In Q1, which assesses students’ understanding of the definition of FE, 5% of the students were unable to provide a correct answer (score 0) prior to the intervention (A16pre: ‘Fascinating’), and 77.6% provided a partially correct response (scores 1 and 2: A38pre: ‘I study bugs in a decomposing corpse’ and A68pre: ‘It is the study of insects that helps in the investigation of the death of an individual’, respectively). Only 17% of respondents correctly defined the term (score 3): A7pre: ‘The science of determining the date of death through the various insects and their state of evolution present in the corpse’. Notably, some definitions were compatible with the idea of SG, such as A65pre: ‘Study of the life that is created from the decomposition of the body’. After the intervention, no incorrect answers were recorded, and the proportion of correct responses (score 3) increased to approximately 29% of respondents.
In Q2, which specifically asks about the distinctive morphological characteristics of the main organisms involved in FE, the number of incorrect responses prior the intervention was very high (68.42% of respondents) (A27pre: ‘Flies, larvae…’) but decreased to 9.21% after the intervention. Certain responses were compatible with SG, such as A65pre: ‘They lay eggs and are created from decomposition’. After the intervention, the proportion of correct answers increased notably, from 5.26% to 40.79% (A11post: ‘They have an exoskeleton; their body is divided into thorax, abdomen and head; they have 6 legs and 2 or 4 wings; their life cycle usually goes through larva, pupa and adult; they have two antennae’).
Regarding Q3 and Q4, which indirectly assess students’ conception of the existence or non-existence of SG in two different contexts (meat exposed to the environment in Q3, and a closed flour jar in Q4), students demonstrated greater difficulty in justifying the presence of larvae in the closed flour jar compared to the meat, both before (score 0: 75% for flour, 53.95% for meat) and after the intervention (11.84% vs. 5.26%, respectively). Before the intervention, no students provided correct answers (score 3) to Q4, while approximately 9% answered correctly in Q3. After the intervention, correct explanations for the presence of larvae in meat increased to 57.89% (A31post: ‘As the meat rots, it generates odors that attract insects such as dipterans, which lay eggs from which larvae hatch’). However, correct responses regarding the flour jar remained relatively low (17.11%) (A72post: ‘It is most likely that at some point when the canister was improperly closed or even in the flour factory itself some arthropod has laid eggs in the flour, which after some time have hatched inside the closed canister’).
It is worth noting the presence of answers compatible with SG, such as the responses to Q3: A2pre: ‘The putrefaction of meat’; A58pre: ‘They may have been created from the fusion of a series of atmospheric and chemical conditions’ or A65pre: ‘Meat when it decomposes creates maggots’. Similar misconceptions were observed in Q4: A22pre: ‘I don’t know exactly, I think it could be because when the flour expires it ferments creating bacteria and through those bacteria the worms would appear, but I don’t know if it makes much sense’ or A55pre: ‘They have been formed from the flour itself, as it has not been used over time’. Some students even justified both answers in the same way, reinforcing their belief in SG: Q4 A58pre: ‘I think the same as I answered before [Q3], a series of atmospheric conditions have led to the creation of organisms in that environment’.
In Q5, students were asked about the existence of SG, choosing between: Option (A) ‘larvae appear spontaneously in meat and flour’, or Option (B) ‘it is impossible for larvae to appear spontaneously in these products’. Before the intervention, only 1.32% of students correctly justified option B, while 36.84% either did not answer or selected option A (score 0). For example: A16pre: ‘Yes they can appear spontaneously, with the right environmental conditions and depending on the state of the food they would appear sooner or later’. Additionally, 52.63% of students selected option A but argued in favor of option B (A26pre: ‘A. Because when the meat decomposes, the insects come in, such as larvae and flour, I don’t know’), or selected option B but justified option A (A72pre: ‘B. Because there has to be a process of decomposition of the meat or flour for the larvae to appear’). These responses were assigned a score of 1 in both cases. After the intervention, the percentage of correct answers (score 3) increased significantly from 1.32% to 35.53%. For example, A64post: ‘B. There is no spontaneous generation, every living being comes from another, an arthropod has appeared before and has left its eggs there’). Despite this improvement, a significant proportion of students (46%) still expressed doubts or were unable to justify their answer (score 1): A25post: ‘I would choose option B, as organisms do not come out of nowhere’.
In these last three questions (Q3–Q5), a notable gender difference was observed before the intervention. The percentage of incorrect responses (score 0) was significantly higher among women than men (Q3: 4.29% vs. 25%; Q4: 82.14% vs. 55%; Q5: 46.43% vs. 10%). However, this difference decreased drastically after the intervention (Q3: 7.14% vs. 0%; Q4: 14.29% vs. 5%; Q5: 1.79% vs. 0%). These results suggest that the intervention was effective in equalizing knowledge between genders.
Finally, in Q6, which asked students to identify other organisms that might be found in meat or flour, no major differences were observed before and after the intervention. A small percentage of students provided fully correct answers (score 3) in both cases (approximately 11% before and 12% after). For example, A33post: ‘Diptera, Coleoptera, Lepidoptera, Hymenoptera in adult stage, microbiology as fungi… We have living creatures accidentally on corpses and we have insects (within hexapods) and arthropods’. The most notable change was a decrease in incorrect answers (score 0, from 29% to 12%) and an increase in partially correct answers (score 1), where students mentioned at least one term related to one of the blocks (from 45% to 65%).
On average, when considering all questions together (sum of the six questions, with a maximum score of 18 points), the results obtained in the questionnaires were higher after the TLS than before (Table 5). In fact, before the intervention, none of the years or gender groups reached half of the possible total (i.e., 9 out of 18). However, except for the group of male students in the second year, this intermediate score was always exceeded after the didactic intervention. Additionally, female students showed lower scores before the intervention (in the overall calculation) but, on average, reached or even surpassed male students after the learning process (Table 5).

4.3. Student Learning

The model with the lowest AICc for assessing student learning throughout the intervention included only the following fixed variables: time of questionnaire completion (pre- or post-intervention), gender and the interaction between these two variables (Table A3). Academic level and educational background were not selected by the model, as they did not have a significant effect. Therefore, we cannot conclude that these variables influenced the questionnaire results. The combination of the selected fixed effects (gender, time of questionnaire completion, and their interaction) explained more than half of the observed variation (R2m = 0.59), increasing slightly when random variables were included (R2c = 0.69). Among the random variables, inter-student variability had a greater influence than inter-annual variability. Among the fixed variables, significantly higher scores were observed in the post-intervention questionnaire, making time of questionnaire completion the most important factor in explaining the observed differences. This was reflected in a higher deviance score. Furthermore, female students initially scored significantly lower than male students. However, an interaction approaching significance (p = 0.060) was observed between gender and questionnaire timing, suggesting that female students exhibited greater learning gains than male students after the didactic intervention (Figure A1).
Finally, according to the Generalized Additive Model, we identified a significant relationship between the post-intervention questionnaire results and students’ self-assessment (p = 0.002), explaining 35.8% of the observed variability. Students with higher scores also reported higher self-perceptions of learning, while those with lower scores reported lower self-perceptions. However, the relationship between these two variables did not follow a linear trend (Figure 1).

5. Discussion

Post-intervention questionnaire results revealed significant improvements following the implementation of the TLS, supporting the hypothesis that contextualized learning enables students to refute ideas compatible with SG and improve NOS understanding, in line with previous studies (Byington, 2001; Cobo et al., 2022; Custodio et al., 2015). Furthermore, active student participation played a crucial role in enhancing learning outcomes. Active engagement in discussions and inquiry-based activities allowed students to refine their reasoning skills and develop a more critical approach to scientific concepts, as described by other authors (Ahmed et al., 2023; Stender et al., 2018; Strat et al., 2024). The interactive and participatory nature of TLS facilitated knowledge retention, reinforcing the importance of student involvement in the learning process. The responses given to Q3, Q4 and Q5 suggest that replicating Redi’s experiments helped students acquire scientific tools to critically analyze SG and understand associated concepts such as the metamorphic cycle of insects. Moreover, IBL and PBL proved effective in promoting deep and meaningful learning, autonomy and critical thinking, as discussed by other authors (Cobo et al., 2022; Kokotsaki et al., 2016; Strat et al., 2024).
On the other hand, the pre-intervention questionnaire analysis revealed gender differences, with women scoring lower than men. This may be related to a greater aversion towards insects among females, as highlighted in previous research (Azil et al., 2021; Davey et al., 1998; Stoyanova & Hope, 2012). However, these conclusions must be taken with caution as the gender composition of the participants in this intervention was female-biased, especially during the second year (with only two male students). Despite this, these potential gender differences disappeared following the didactic intervention, suggesting that the training equalized knowledge and attitudes between male and female students. This aligns with research highlighting the role of educational context as a key factor in reinforcing scientific reasoning, overcoming cultural stereotypes, and promoting equality in learning (Boser et al., 2014). Additionally, previous studies have indicated that female students tend to exhibit greater self-discipline, self-regulation, and effort in their schoolwork, which translate into higher academic achievement, even in areas and subjects traditionally associated with boys (Burušić & Šerić, 2015; Kenney-Benson et al., 2006). Since the 1990s, empirical evidence has been gathered regarding its underlying causes (Burušić & Šerić, 2015).
In the context of this study, the reduction of gender differences after the didactic intervention could also be explained by the Pygmalion effect, which suggests that students perform better when teachers have high expectations (Boser et al., 2014). Teacher expectations are closely linked to students’ self-perception, and the Pygmalion effect is not only manifested at the individual level, but also at the group level. Thus, high teacher expectations for an entire class can result in higher individual and collective achievement (Rubie-Davies & Hattie, 2025; Szumski & Karwowski, 2019). As a result, female students were able to attain the same level of knowledge and attitudes as their male peers.
Negative perceptions of insects, which are deeply rooted in popular culture, constitute an additional barrier to scientific literacy. Many people perceive insects as disgusting and repulsive (Scudder, 2009) or associate invertebrates with fear, aversion, and ignorance (Kellert, 1993). Such negative attitudes, often developed before puberty, can escalate into uncontrollable and debilitating fear of arthropods, including insects (entomophobia) (Fernández-Rubio, 2016). In fact, everyday language reinforces these perceptions through expressions such as ‘it’s just a bug’ or ‘they are all pests’ (Gunderman & White, 2021). Meanwhile, the media and cinema reinforce this negative perception by caricaturing, distorting or exaggerating the size, behavior, and perceived threat of insects, often portraying them as terrifying monsters that attack humans (Mariño Pérez & Mendoza Almeralla, 2006; Pérez-Velázquez, 2011). These influences perpetuate stereotypes, negatively impacting scientific literacy from an early age. Nevertheless, both school education and social learning can serve as powerful tools to reshape these perceptions, providing accurate information and fostering positive attitudes towards insects, thereby influencing students’ family and school environments (Breuer et al., 2015; McClurg, 1984; Muñiz Estévez & Torralba Burrial, 2022; Schneider & Meyer, 2024; Sitar & Rusu, 2023). Our findings also support the idea that gender stereotypes and negative attitudes towards insects can be effectively challenged through appropriate education.
The relationship between post-intervention questionnaire results and students’ self-perception of learning suggests that those who scored higher also reported greater self-perception of learning (and conversely, lower scores correlated with lower self-perception). This indicates that students had a realistic understanding of their knowledge, although this relationship was not strictly linear (Figure 1). These results underscore the importance of designing interventions that encourage critical and realistic self-assessment.
Despite the overall effectiveness of the TLS, some limitations were identified. The TLS emphasized entomology over microbiology, affecting Q6 responses. Students struggled to apply microbiological knowledge when answering this question. Future iterations should incorporate specific sessions on microbial biodiversity or provide clearer guidance on how to address these aspects.
This study confirms that the TLS was effective in dismantling misconceptions, enhancing students’ understanding of SG and FE, overcoming gender differences in knowledge and attitudes, and promoting meaningful learning. While prior scientific background did not significantly influence initial knowledge, the intervention successfully fostered conceptual change. In the health sector, where entomology is of critical importance, it is essential to overcome misconceptions and cultural stereotypes related to insects. Professional training in this field should include fundamental principles of entomology, not only to disprove misconceptions such as SG, but also to prepare students for real-world scenarios, such as processing samples from decomposing corpses (Infante-Cabezón & Soria-Iglesias, 2020) or diagnosing cutaneous myiasis caused by dipteran larvae (Menéndez-Capote et al., 2020). This educational training becomes even more relevant given the increase in insect-borne diseases and severe pathologies of entomological etiology (World Health Organization, 2024). The inclusion of concepts such as the metamorphic cycle of insects would significantly strengthen the technical and scientific preparation of future professionals in this VET cycle.
Finally, future research should further explore the role of non-academic learning environment in shaping alternative conceptions and developing interdisciplinary strategies that integrate different contextualized approaches, combining FE and microbiology to provide more comprehensive training. This will help ensure that students acquire a thorough understanding of biological processes relevant to their field. These measures will contribute to stronger scientific literacy and better prepare VET students to address complex challenges in healthcare with a more robust scientific foundation.

QuestionStatement
Q1How would you define Forensic Entomology?
Q2What are the distinctive morphological characteristics of the main organisms involved in Forensic Entomology?
Q3You have been away for the weekend and left the hamburger thawing on the kitchen table on an uncovered plate. Upon your return, you notice white maggots in the meat. How would you explain their appearance?
Q4When you take the jar of flour from a kitchen shelf, you notice that, although nobody has opened it for a long time, there are worms inside along with the flour. How would you explain their appearance?
Q5IQ: Imagine you were given the opportunity to scientifically prove that larvae: (a) Can spontaneously appear on meat and flour. (b) Cannot spontaneously appear on meat and flour. Which option would you choose? Please, justify your answer.
FQ: You have been given the opportunity to scientifically demonstrate that larvae: (a) Can spontaneously appear on meat and flour. (b) Cannot spontaneously appear on meat and flour. Which option did you choose? Please, justify your answer.
Q6Besides larvae, do you think that other types of organisms can appear? List as many examples as you can.
