This is a case study of a physics undergraduate who claimed that he “uses physics to understand other subjects.” This statement suggested that this student could describe issues concerning the transfer of learning and especially instances of far transfer. Detailed instances of far transfer have been difficult to replicate in lab settings. Therefore, three interviews were designed to investigate this student’s claims about using physics to understand other subjects as a means to better understand far transfer processes. Transfer in this case study is defined as the personal construction of relations of similarity. Furthermore, I operationalize this definition of transfer via 12 aspects of transfer derived from the work of several contemporary researchers who study the transfer of learning. As part of this case study I also investigate the subject’s motivation for engaging in far transfer. Directions for future research are discussed which includes the need to study the role of personal epistemology in far transfer as well as a larger investigation of students who transfer broadly across school subjects.  相似文献

This study describes the process of developing and validating an instrument that measures students’ innovation capacities as a higher education outcome. We introduce an interdisciplinary theoretical framework used to generate items and cover extant literature drawn primarily from the fields of higher education and entrepreneurship studies. We further discuss our use of latent trait theory and item response models to guide instrument development and measure scoring. We then provide the results of a second-order confirmatory factor modeling procedure, which indicated robust model fit. We close by discussing findings and offering implications for both higher education scholars and institutional researchers.  相似文献

Fifteen-day-old rats made random choices in a T-maze, while adult levels of alternation (approximately 70%) were noted among 30-day-olds. Also, younger pups were insensitive to a lengthening of the intertrial interval, unlike older animals whose rate of alternation decreased when a 1-h delay was interposed between arm entries. These findings are consistent with the hypothesis that hippocampal development is a factor in the ontogeny of postweaning locomotion. The unsystematic pattern of goal-arm selections among 15-day-olds suggests that ontongenetic variation in the utilization of stimuli may underlie developmental shifts in spontaneous alternation.  相似文献

Children raised in neighborhoods with low socioeconomic status (SES) are at risk for low academic achievement. Identifying factors that help children from disadvantaged neighborhoods thrive is critical for reducing inequalities. We investigated whether children’s prosocial behavior buffers concurrent and subsequent academic risk in disadvantaged neighborhoods in Bradford, UK. Diverse children (N = 1,175) were followed until age seven, with measurements taken at four times. We used governmental indices of neighborhood-level SES, teacher observations of prosocial behaviors, and direct assessments of academic achievement. Neighborhood SES was positively associated with academic achievement among children with low levels of prosocial behavior, but not among children with high levels of prosocial behavior. Prosocial behavior may mitigate academic risk across early childhood.  相似文献

Millions of college students in the U.S. are enrolled in online courses, with the global pandemic resulting in a “pivot to online” for educational and health reasons. African-American college students continue to face barriers to academic success, and this response to Kuo and Belland (in Educ Technol Res Dev 64(4):661–680, 2016) investigates how the concept of “learner interaction” supports success. Finally, this response includes examples from online courses informed by “critical humanizing pedagogy,” in which social interaction is a key driver of learning.

Interactive computerized modules have been linked to improved retention of material in clinical medicine. This study examined the effects of a new series of interactive learning modules for preclinical medical education, specifically in the areas of quiz performance, perceived difficulty of concepts, study time, and perceived stress level. We randomly allocated 102 medical student volunteers into control and experimental groups. All participants studied selected anatomical and physiologic concepts using existing material (lecture notes, textbooks, etc.), while those in the experimental groups used the new interactive modules as well. All participants completed a quiz to test their knowledge of the assigned concepts and a survey to assess their subjective experiences in studying with the modules. We found a trend toward higher quiz scores in the experimental group relative to the control group, though it did not reach statistical significance (P = 0.31). Perceived concept difficulty was significantly reduced among those who studied with the modules (P < 0.001), and the number of hours spent studying the concepts was significantly increased (P = 0.028). Of those who used the modules, 83% rated them as “very helpful” or “extremely helpful.” No significant differences existed between participants' reported stress levels during the course of the study (P = 0.44). Our data suggest that medical students may learn more effectively and feel less intimidated by difficult concepts when interactive modules supplement traditional instruction.

The current study explored the values preservice teachers use as motivation for pursuing a teaching career. Preservice teachers (N = 97) from a large Northeastern urban university were chosen to complete a survey measuring personal utility value, social utility value, and epistemic value. Data analysis was conducted using exploratory factor analysis, correlations, multivariate analysis of variance (MANOVA), and multivariate analysis of covariance (MANCOVA). Results indicated moderate and significant correlations among subscales; a two-group MANOVA demonstrated that females were rated higher on the subscale desire to work with children/adolescents and Secondary Education participants rated highest on social contribution; and a MANCOVA using sex as the covariate demonstrated that participants pursuing Early Childhood Education were rated higher on the personal utility value main scale and the time for family and job transferability subscales.  相似文献

This study investigated inclusion of epistemic value into Richardson and Watt Factors Influencing Teaching Choice (FIT-Choice) framework to produce a more robust, useful teacher motivation model. We specifically examined pre-service teachers’ social utility value (SUV), personal utility value (PUV) and epistemic value regarding pursuing future professional engagement and development. Using principal axis factoring, we found four main factors: PUV, SUV, epistemic value—future value of knowledge (EVF) and persistence/satisfaction. These factors were then used in a structural equation model (SEM) to predict pre-service teachers’ intentions to pursue future professional engagement. Results provided the following three insights: (a) SUV was the most consistent, positive predictor of professional engagement and predicted all dependent variables; (b) EVF was a newly identified factor and a positive predictor of pre-service teachers’ desire to pursue a leadership position and (c) PUV negatively predicted planned effort and a desire to pursue a leadership position.  相似文献

Military service is acknowledged as one of many elements voters use to evaluate candidates, but it has primarily been studied as a univariate element of a candidate’s biography. This project experimentally manipulates veteran status, gender, and partisanship as potentially interactive heuristics for evaluation of a hypothetical candidate specifically regarding military issues. We found an almost universal benefit enjoyed by veterans over civilians regardless of whether the candidate was a member of the participant’s partisan ingroup or outgroup. We also found little evidence of a gender penalty, and even a benefit for women candidates who were veterans, though this benefit was restricted to evaluations from Republican women. We also found that Democratic respondents assigned a penalty to outgroup veteran men candidates. We explain these nuanced findings in the context of moderation by gender mis/alignment between participant and candidate. Implications of the study are offered.  相似文献

Early childhood poverty is a prevalent social issue, both in the United States and in the wider international community. It has been well established that factors associated with poverty, including familial income and parental education level, can negatively affect children’s language and cognitive development, which can result in academic achievement deficits that compound across the lifespan. Additional environmental factors, specifically maternal and children’s own social–emotional development, have also been shown to impact these sensitive early childhood developmental processes. Although individual components that relate to language and cognitive development in young children have been identified, additional examination of potential associative relationships between these components is warranted. Therefore, this study explored socio-economical, health, and developmental relationships between 122 caregiver–child dyads enrolled in an Early Head Start Program where children were 1–36 months old. Results indicated strong bidirectional correlations between children’s cognitive and language development. Multiple linear regression path analysis indicated that children’s cognition and social–emotional wellbeing have a significant direct effect on their language development. Additionally, language and fine motor development were found to have a significant direct effect and social–emotional wellbeing mediated an indirect effect through language on children’s cognitive development. In light of socioeconomic and sociocultural challenges, the importance of nurturing children’s social–emotional development in relation to language and cognitive development is discussed.  相似文献
