3.1. Effects of the CSN Program on STEM Affinity
STEM affinity encompasses five key subcomponents: STEM identity, personal interest in STEM, self-concept of ability in STEM, STEM values, and attitudes toward STEM. As shown in
Table 2, the implementation of the CSN program resulted in statistically significant improvements across all five dimensions. The most pronounced gain was observed in participants’ attitudes toward STEM, suggesting that the program effectively cultivated more favorable perceptions and a greater appreciation for the subject. This positive shift in attitudes is particularly noteworthy, as it has the potential to enhance teacher candidates’ engagement with STEM content and increase their motivation to teach STEM subjects confidently and enthusiastically in future classrooms.
Figure 1 visually represents the mean differences in STEM affinity components before and after the intervention, emphasizing the growth in teacher candidates’ STEM identity, self-concept, value, personal interest, and attitudes.
3.1.1. STEM Identity
The analysis of responses related to STEM identity provides important insights into the evolving self-perception of teacher candidates from the United States and South Korea. As illustrated in
Table 3, mean scores for all items assessing STEM identity increased following participation in the CSN program, indicating an overall positive shift in self-perception for both groups.
Notably, American teacher candidates reported significantly higher mean scores than their Korean counterparts on items 3 (“I am good at STEM”) and 4 (“I think of myself as a professional in STEM”), suggesting greater confidence in their STEM abilities and professional identity. This disparity in self-perception may reflect broader cultural influences on self-efficacy. Although Korean candidates were high academic performers and STEM majors, many expressed uncertainty regarding their STEM proficiency. Engaging with peers from a different educational system and encountering alternative approaches to problem-solving might have made some participants more aware of areas for growth, leading to more conservative self-ratings. This shift does not necessarily indicate a loss of actual competence, but rather a recalibration of self-perception in light of new experiences and higher perceived benchmarks. These findings are consistent with
Kim (
2022), who reported that Korean teacher candidates often exhibit lower self-efficacy in inquiry-based teaching despite strong content knowledge. Cultural norms that emphasize modesty or discourage self-assertion may further contribute to this contrast in confidence between U.S. and Korean participants. Together, these factors suggest that the decrease in self-rating may reflect increased self-awareness rather than diminished ability.
3.1.2. Personal Interest in STEM
The evaluation of personal interest in STEM, as detailed in
Table 4, provides meaningful insights into the impact of the CSN program on teacher candidates from both the United States and South Korea. Mean scores across all items measuring personal interest increased following the program, indicating enhanced engagement and enthusiasm for STEM. While American participants consistently reported slightly higher scores than their Korean counterparts, both groups demonstrated similar patterns of improvement, suggesting the program was effective across cultural contexts.
The most substantial gain was observed for item 5, which assesses the connection between STEM and everyday life. This improvement may be attributed to the program’s emphasis on designing culturally integrated STEM lessons. By incorporating elements such as art, nature, and architecture from their respective cultural backgrounds, teacher candidates were able to perceive STEM as more relevant and applicable in diverse, real-world settings.
Qualitative reflections reinforced these findings. Participants noted that the program broadened their perspectives on how STEM can intersect with cultural themes. Comments such as, “I am more open to incorporating different cultures into STEM topics”, and “This project made STEM more interesting to me by connecting it to cultural contexts”, underscore the program’s role in fostering deeper, more meaningful interest in STEM education.
3.1.3. Self-Concept of Ability in STEM
As shown in
Table 5, the evaluation of self-concept of ability in STEM offers important insights into how American and Korean teacher candidates perceive their competence in STEM disciplines. Consistent with trends observed in STEM identity (
Table 3), American candidates reported higher mean scores across all self-concept items, suggesting a stronger self-perception of STEM ability compared to their Korean counterparts. This pattern reflects previous findings from international assessments such as TIMSS and PISA, where Korean students, despite high academic performance, tend to report lower confidence in their STEM abilities (
Kwak, 2018).
Among Korean teacher candidates, participation in the CSN program led to significant gains in self-concept scores, indicating that the program helped address some confidence-related challenges. While a few participants noted limited changes—citing the elementary-level focus of lesson design—others reported increased confidence, particularly in applying scientific knowledge within cultural contexts and communicating it effectively. This variation underscores the individualized impact of the program. As one participant remarked, “It was too short to have substantial changes, but I feel a little more confident about STEM than before”, suggesting that even short-term exposure to culturally relevant STEM instruction can support the development of teacher candidates’ confidence in their STEM teaching capabilities.
3.1.4. Perceptions of STEM Values
The evaluation of responses to STEM values items, presented in
Table 6, offers meaningful insights into how American and Korean teacher candidates perceive the importance and relevance of STEM education. Consistent with earlier findings, Korean participants initially reported lower perceptions of STEM value compared to their American counterparts. This aligns with prior research by
Kwak (
2018), which noted that Korean students ranked 36th to 37th out of 39 countries in the 2015 TIMSS assessment regarding the perceived value of science education.
Following participation in the CSN program, both groups exhibited notable improvements in their value perception scores. This suggests that the program effectively enhanced participants’ appreciation of STEM, regardless of cultural background. Open-ended feedback further supported this trend, with teacher candidates emphasizing the meaningfulness and future importance of understanding STEM concepts.
These findings reflect a positive shift in attitudes toward STEM and suggest that the CSN program contributed to fostering a deeper recognition of STEM’s relevance in both education and broader society. This is particularly significant, as valuing STEM is essential for teacher candidates who will be responsible for promoting STEM engagement and literacy in their future classrooms.
3.1.5. Attitudes Toward STEM
The evaluation of responses to attitudes toward STEM items reveals significant positive changes (
Barbera et al., 2008) among teacher candidates following their participation in the CSN program (
Table 7). Participants showed improved attitudes across all STEM-related items after completing the program, indicating that the CSN effectively enhanced their overall perception of STEM education.
Although there were slight differences in mean scores between American and Korean teacher candidates, the overall distribution patterns were similar. Both groups exhibited strong interest and positive attitudes toward STEM, demonstrating a shared appreciation for the subject despite cultural differences.
Open-ended feedback from participants further highlighted this shift in attitude. For example, one participant shared, “I hadn’t thought about applying STEM to culture-related topics before, so this project made STEM more interesting to me”. Such reflections emphasize the program’s success in making STEM education more relatable and engaging for teacher candidates. This feedback underscores the CSN program’s role in encouraging teacher candidates to integrate cultural contexts within STEM education. This approach not only fosters greater interest in STEM but also enriches the learning experience by connecting scientific concepts to real-world cultural applications.
3.2. Effects of the CSN Program on Cultural Intelligence (CQ)
The CSN program significantly enhanced teacher candidates’ cultural intelligence (CQ), better preparing them to engage effectively in diverse educational environments. By integrating scientific concepts with cultural contexts, the program helped candidates connect STEM content to traditions, heritage, and the arts from various cultures. This approach enriched their understanding of both STEM education and cultural diversity.
Teacher candidates implemented culturally relevant lessons with elementary students, providing authentic, hands-on teaching experiences that bridged theory and practice. These real-world applications deepened their capacity to deliver STEM instruction in culturally responsive ways.
Additionally, collaborative exchanges with teachers from partner countries offered valuable insights into differing educational systems, classroom norms, lesson planning strategies, and teacher roles. For many Korean teacher candidates, teaching American elementary students for the first time proved to be a transformative experience. Despite initial challenges in unfamiliar classroom settings, they reflected positively on the opportunity, highlighting personal and professional growth. Likewise, American candidates reported increased appreciation for global perspectives and enhanced teaching skills.
Pre- and post-program assessments using the Cultural Intelligence Scale (CQS) revealed statistically significant improvements across all four CQ domains: cognitive, metacognitive, motivational, and behavioral (
Table 8). These findings highlight the CSN program’s effectiveness in fostering teacher candidates’ ability to navigate and succeed in culturally diverse educational contexts.
Figure 2 illustrates the pre- and post-program mean scores for teacher candidates’ cultural intelligence across four dimensions.
3.2.1. Metacognitive Cultural Intelligence (CQ)
An analysis of teacher candidates’ responses reveals significant growth in metacognitive cultural intelligence (CQ) as a result of their participation in the CSN program. Metacognitive CQ, as defined by
Van Dyne et al. (
2008), refers to an individual’s awareness and control of their cultural thinking during intercultural interactions. This form of CQ is essential for fostering active reflection and adaptability in multicultural educational settings.
Throughout the program, teacher candidates showed a marked increase in their curiosity about and appreciation for cultural differences. Many began the program perceiving cultural diversity as unfamiliar or distant. However, through sustained interaction with international peers, they developed a greater understanding of shared human experiences across cultures—an indication of enhanced metacognitive CQ.
Reflective statements from participants illustrate this growth. One candidate remarked, “The event opened my eyes to how important and special it is to incorporate culture into students’ learning. It strengthens their knowledge and awareness of different people and their cultures”. Another shared, “It strengthened my skills by helping me analyze all the different ways culture could be tied in, even if it’s not immediately obvious”. These reflections underscore participants’ deepened ability to critically engage with cultural content in educational contexts—a key indicator of metacognitive CQ.
As shown in
Table 9, metacognitive CQ scores improved significantly following the program. Although Korean teacher candidates scored slightly lower than their American counterparts, their gains were substantial. Given their initial limited exposure to English-speaking classroom environments, this progress highlights the CSN program’s effectiveness in fostering cultural awareness and reflective thinking.
Overall, the growth in metacognitive CQ demonstrates that the CSN program successfully equipped teacher candidates with the critical skills needed to incorporate diverse cultural perspectives into their teaching. This development strengthens their capacity to create inclusive, culturally responsive learning environments and underscores the program’s value in preparing educators for today’s multicultural classrooms.
3.2.2. Cognitive Cultural Intelligence (CQ)
Cognitive cultural intelligence (CQ) is defined as “an individual’s awareness and understanding of norms, practices, and conventions in diverse cultural settings” (
Van Dyne et al., 2008, p. 17). This dimension of CQ is essential for recognizing cultural similarities and differences, enabling individuals to make informed decisions and engage effectively in multicultural contexts.
The CSN program significantly enhanced teacher candidates’ cognitive CQ by immersing them in various cultural elements of the host nation, including landscapes, traditional games, music, art, and crafts. For Korean teacher candidates, the experience was particularly impactful, as they gained a deeper understanding of how scientific concepts are communicated in American classrooms. They observed linguistic patterns used in classroom questioning and response, as well as strategies that promote interactive and student-centered learning.
One participant shared, “In our presentation, we talked about volcanic landscapes of Jeju Island in South Korea and compared them with similar landscapes in the U.S. In this way, I got to know about some famous national parks in various states”. This reflection illustrates how cross-cultural comparisons broadened candidates’ geographical and cultural knowledge, contributing to the development of cognitive CQ.
Another teacher noted, “By preparing the class, I learned more about my own Korean culture. I also tried to use sentences I learned from videos of American schools. This way, I felt more fluent in a foreign language, and I understood how differences in word choice affect classroom atmosphere”. This statement highlights the dual benefits of the program—enhancing both cultural self-awareness and cross-cultural communication skills.
As shown in
Table 10, cognitive CQ scores improved significantly among teacher candidates following the program. Notably, Korean participants reported higher mean scores than their American peers, both before and after the program. This may reflect their prior exposure to American culture, despite having comparatively lower English proficiency. While American candidates expanded their understanding of Korean culture, many still recognized gaps in their knowledge. Korean candidates, on the other hand, demonstrated a stronger grasp of classroom communication (e.g., item 6) but reported limited understanding of U.S. legal, economic, and social systems, including marriage customs.
These findings highlight the importance of ongoing cultural exchange and education. Programs like CSN play a vital role in bridging cultural knowledge gaps and equipping future educators with the cognitive tools needed to navigate and thrive in diverse classroom settings. By fostering greater cultural awareness and understanding, such programs contribute to the development of more inclusive and effective teaching practices.
3.2.3. Motivational Cultural Intelligence (CQ)
Motivational cultural intelligence (CQ) is a critical component for educators, as it reflects their capacity to channel attention and energy toward understanding and engaging with cultural differences—thereby enhancing their effectiveness in diverse educational settings (
Van Dyne et al., 2008). Closely linked to self-efficacy, this dimension of CQ encompasses the confidence and intrinsic motivation to interact with individuals from various cultural backgrounds.
The CSN program significantly strengthened teacher candidates’ confidence in integrating cultural elements into their STEM instruction. Many participants initially expressed concerns about language barriers and unfamiliarity with the host culture. However, as they engaged in collaborative research and lesson design, their appreciation for cultural diversity deepened. One candidate remarked, “Planning the class made me question myself a lot more than usual class plans since I had to consider cultural differences. Through the process, my attitude toward being careful with multicultural students enhanced”.
Candidates also demonstrated proactive efforts to understand and navigate cultural nuances. For instance, one teacher shared, “I also watched some videos of American school classes, and it helped me learn how to adapt to another culture’s non-verbal language of the teacher”. This initiative not only improved their lesson planning but also fostered a more nuanced understanding of teaching in multicultural environments.
Furthermore, the experience of preparing lessons in a non-native language prompted candidates to reflect critically on both their own and others’ cultures. As one participant noted, “I got another experience of preparing a lesson using a language that is not my mother language, and I could think about not only researching my culture but also someone else’s culture. I believe this experience will enhance my cultural competence”. This reflection illustrates the program’s transformative impact on enhancing motivational CQ.
As presented in
Table 11, motivational CQ scores increased significantly post-program, with notable improvements across most survey items. Interestingly, Korean teacher candidates exhibited greater gains than their American counterparts, ultimately surpassing them in overall mean scores. While American candidates initially scored higher on specific items, some experienced slight declines—particularly on item 13—suggesting challenges in sustained engagement with unfamiliar cultures.
These findings align with
Peng et al. (
2015), who found that motivational CQ significantly predicted cross-cultural adaptation and psychological comfort among study-abroad participants, particularly when supported by a strong cultural identity. Similarly,
Alexander et al. (
2021) reported that intensive, experiential cultural development programs led to substantial increases in cognitive, metacognitive, and behavioral CQ, though gains in motivational CQ were limited—a pattern mirrored in our study. A recent systematic review also highlighted that motivational CQ is more resistant to change without prolonged or structured interventions (
Alexander et al., 2021;
Urgun et al., 2025).
Thus, the observed divergences between American and Korean participants underscore the importance of continuous cultural training and ongoing engagement to nurture motivational CQ effectively. The CSN program’s emphasis on motivational CQ—through immersive interaction and reflective practices—was instrumental in fostering teacher candidates’ confidence, cultural curiosity, and readiness to embrace diversity in their teaching practices.
3.2.4. Behavioral Cultural Intelligence (CQ)
Behavioral cultural intelligence (CQ) is a crucial skill for educators, as it reflects their ability to modify verbal and nonverbal behaviors to interact effectively with individuals from diverse cultural backgrounds (
Van Dyne et al., 2008). This adaptability is essential for fostering meaningful communication and mutual understanding in multicultural educational settings.
The CSN program, conducted primarily in English, presented communication challenges—particularly for Korean teacher candidates who were less fluent than their American peers. Despite this, interactions between participants were largely successful and enriching. As one candidate shared, “Cooperating with students from different countries helped me develop cultural competence by communicating in a different language and sharing what we know about our culture”. This quote illustrates the dual nature of language as both a barrier and a bridge in intercultural exchange.
Digital tools such as Padlet, Zoom, and Microsoft Teams played a significant role in supporting communication. For example, Padlet enabled participants to share lesson plans and cultural insights in advance, allowing Korean teachers time to understand their American counterparts’ perspectives. One candidate reflected, “By posting our lessons and providing feedback on Padlet, we were able to interact with future STEM teachers from other cultures and learn about their cultural concepts”. This structured, asynchronous format helped facilitate collaboration and reduce linguistic and cultural gaps.
As shown in
Table 12, behavioral CQ improved among teacher candidates following the program. American participants demonstrated adaptability by modifying their communication strategies—such as slowing their speech, incorporating pauses, and adjusting nonverbal cues like facial expressions (items 17–20). While Korean teachers exhibited slightly smaller gains, they made commendable efforts to adjust their verbal communication styles (item 16), reflecting a willingness to bridge cultural divides.
One candidate noted, “Padlet allowed us to take the time needed to accept an unfamiliar culture. I could briefly explain our culture to them”. Such reflective practices contributed not only to the development of behavioral CQ but also to a greater appreciation for cultural diversity. Ultimately, these interactions fostered a more inclusive and collaborative learning environment.
