Teachers’ perception of STEM integration and education: a systematic literature review
BackgroundFor schools to include quality STEM education, it is important to understand teachers’ beliefs and perceptions related to STEM talent development. Teachers, as important persons within a student’s talent development, hold prior views and experiences that will influence their STEM instruction. This study attempts to understand what is known about teachers’ perceptions of STEM education by examining existing literature.ResultsStudy inclusion criteria consisted of empirical articles, which aligned with research questions, published in a scholarly journal between 2000 and 2016 in English. Participants included in primary studies were preK-12 teachers. After quality assessment, 25 articles were included in the analysis. Thematic analysis was used to find themes within the data. Findings indicate that while teachers value STEM education, they reported barriers such as pedagogical challenges, curriculum challenges, structural challenges, concerns about students, concerns about assessments, and lack of teacher support. Teachers felt supports that would improve their effort to implement STEM education included collaboration with peers, quality curriculum, district support, prior experiences, and effective professional development.ConclusionsRecommendations for practice include quality in-service instruction over STEM pedagogy best practices and district support of collaboration time with peer teachers. Recommendations for future research are given.

Cognitive Functions in Elite and Sub-Elite Youth Soccer Players Aged 13 to 17 Years
Soccer players are required to anticipate and react continuously in a changing, relatively unpredictable situation in the field. Cognitive functions might be important to be successful in soccer. The current study investigated the relationship between cognitive functions and performance level in elite and sub-elite youth soccer players aged 13-17 years. A total of 47 elite youth soccer players (mean age 15.5 years, SD = 0.9) and 41 sub-elite youth soccer players (mean age 15.2 years, SD = 1.2) performed tasks for \"higher-level\" cognitive functions measuring working memory (i.e., Visual Memory Span), inhibitory control (i.e., Stop-Signal Task), cognitive flexibility (i.e., Trail Making Test), and metacognition (i.e., Delis-Kaplan Executive Function System Design Fluency Test). \"Lower-level\" cognitive processes, i.e., reaction time and visuo-perceptual abilities, were also measured with the previous tasks. ANOVA's showed that elite players outscored sub-elite players at the \"higher-level\" cognitive tasks only, especially on metacognition (p < .05). Using stepwise discriminant analysis, 62.5% of subjects was correctly assigned to one of the groups based on their metacognition, inhibitory control and cognitive flexibility performance. Controlling for training hours and academic level, MANCOVA's showed differences in favor of the elite youth soccer players on inhibitory control (p = .001), and cognitive flexibility (p = .042), but not on metacognition (p = .27). No differences were found concerning working memory nor the \"lower-level\" cognitive processes (p > .05). In conclusion, elite youth soccer players have better inhibitory control, cognitive flexibility, and especially metacognition than their sub-elite counterparts. However, when training hours are taken into account, differences between elite and sub-elite youth soccer players remain apparent on inhibitory control and cognitive flexibility in contrast to metacognition. This highlights the need for longitudinal studies to further investigate the importance of \"higher-level\" cognitive functions for talent identification, talent development and performance in soccer.
