Group work in schools with close friends and acquaintances: Linking self-processes with group processes

The present study investigated the relationships between key self-processes, namely independent vs. interdependent self-construal and self-efficacy, with students' attitudes toward working in groups comprised friends and groups comprised acquaintances. The sample consisted of 563 students (280 of Year 10 and 283 of Year 11). Data were collected using questionnaires and analysed using confirmatory factor analysis and structural equation modeling. Interdependent self-construal was found to be both directly and indirectly predictive of students' attitudes toward cooperating with their friends and acquaintances. There was evidence to suggest a “flow on” effect from being self-efficacious for working with friends to being self-efficacious for working with acquaintances.     

Youth's Conceptions of Adolescence Predict Longitudinal Changes in Prefrontal Cortex Activation and Risk Taking During Adolescence

The development of cognitive control during adolescence is paralleled by changes in the function of the lateral prefrontal cortex (PFC). Using a three‐wave longitudinal neuroimaging design (N = 22, M_age = 13.08 years at Wave 1), this study examined if youth's stereotypes about teens modulate changes in their neural activation during cognitive control. Participants holding stereotypes of teens as irresponsible in the family context (i.e., ignoring family obligations) in middle school showed increases in bilateral ventrolateral PFC activation during cognitive control over the transition to high school, which was associated with increases in risk taking. These findings provide preliminary evidence that youth's conceptions of adolescence play a role in neural plasticity over this phase of development.     

Building the BIKE: Development and Testing of the Biotechnology Instrument for Knowledge Elicitation (BIKE)

Identifying students’ conceptual scientific understanding is difficult if the appropriate tools are not available for educators. Concept inventories have become a popular tool to assess student understanding; however, traditionally, they are multiple choice tests. International science education standard documents advocate that assessments should be reform based, contain diverse question types, and should align with instructional approaches. To date, no instrument of this type targeting student conceptions in biotechnology has been developed. We report here the development, testing, and validation of a 35-item Biotechnology Instrument for Knowledge Elicitation (BIKE) that includes a mix of question types. The BIKE was designed to elicit student thinking and a variety of conceptual understandings, as opposed to testing closed-ended responses. The design phase contained nine steps including a literature search for content, student interviews, a pilot test, as well as expert review. Data from 175 students over two semesters, including 16 student interviews and six expert reviewers (professors from six different institutions), were used to validate the instrument. Cronbach’s alpha on the pre/posttest was 0.664 and 0.668, respectively, indicating the BIKE has internal consistency. Cohen’s kappa for inter-rater reliability among the 6,525 total items was 0.684 indicating substantial agreement among scorers. Item analysis demonstrated that the items were challenging, there was discrimination among the individual items, and there was alignment with research-based design principles for construct validity. This study provides a reliable and valid conceptual understanding instrument in the understudied area of biotechnology.     

Challenging Temperament,Teacher–Child Relationships,and Behavior Problems in Urban Low-Income Children: A Longitudinal Examination

Research Findings: Racial/ethnic minority low-income children with temperaments high in negative reactivity are at heightened risk for developing disruptive behavior problems. Teacher–child relationships characterized by high levels of closeness and low levels of conflict may protect against the development of disruptive behaviors in school. The present study examined whether teacher–child closeness and conflict moderated the association between temperamental negative reactivity and growth in disruptive behaviors in low-income Black and Hispanic kindergarten and 1st-grade children. Findings revealed that negative reactivity predicted higher overall levels of in-school disruptive behavior problems at the beginning of kindergarten as well as growth in behavior problems over kindergarten and 1st grade. However, the effect of negative reactivity on disruptive behaviors was attenuated when children had relationships with teachers characterized by high levels of closeness and low levels of conflict. Practice or Policy: Implications for further research and practice are discussed.     

An Engagement-Based Student Typology and Its Relationship to College Outcomes

Using data from the 2006 cohort of the Wabash National Study of Liberal Arts Education, we developed a student typology based on student responses to survey items on the National Survey of Student Engagement. We then examined the utility of this typology in understanding direct-assessment learning outcomes, self-reported gains, grade-point average, and persistence from the first to second year of college. Results from linear and logistic regression models indicated there were relationships between student types and the various outcomes, and that an engagement-based student typology could help deepen our understanding of the college student experience and college outcomes.     

Examining the Relationship between Student Learning and Persistence

Using data from the 2006 cohort of the Wabash National Study of Liberal Arts Education, we examined the relationships between three approaches to measuring student learning outcomes (direct-assessment learning gains, self-reported gains, and college grades) and student persistence from the first to second year. Results from a series of logistic regressions indicated that students’ grade-point averages had the largest explanatory power in student persistence, followed by self-reported gains. Direct-assessment learning gains had the least power in explaining persistence. The findings have implications for the national conversation on student success in college.
