Comparison of Self-Reported and Objectively Measured Sedentary Behavior and Physical Activity in Undergraduate Students

ABSTRACT

The aim of this study was to investigate differences between estimates of sedentary behavior and physical activity (PA) from the International Physical Activity Questionnaire (IPAQ) and accelerometry in undergraduate students. 91 students participated in the study. Sedentary behavior and PA were objectively measured by an accelerometer for 7 days and then self-reported with the IPAQ. Partial correlations were used to assess associations among PA variables and participant characteristics between the methods. Agreement was assessed via the Bland–Altman method. Correlation coefficients between self-reported and objectively measured PA ranged from 0.21 to 0.38 (p≤ 0.05 for all). A higher proportion of students were classified as meeting PA guidelines via self-report compared to objective measurements. Bland–Altman plots revealed acceptable agreement between methods, however, bias was evident for all PA intensities. Sex and lean body mass impacted these differences. Researchers should exercise caution when interpreting PA assessed via the IPAQ in undergraduate students.     

The state of evidence for social and emotional learning: A contemporary meta-analysis of universal school-based SEL interventions

This article provides a systematic review and meta-analysis of the current evidence for universal school-based (USB) social and emotional learning (SEL) interventions for students in kindergarten through 12th grade available from 2008 through 2020. The sample includes 424 studies from 53 countries, reflecting 252 discrete USB SEL interventions, involving 575,361 students. Results endorsed that, compared to control conditions, students who participate in USB SEL interventions experienced significantly improved skills, attitudes, behaviors, school climate and safety, peer relationships, school functioning, and academic achievement. Significant heterogeneity in USB SEL content, intervention features, context, and implementation quality moderated student experiences and outcomes. Strengths and limitations of this evidence and implications for future USB SEL research, policy, and practice are discussed.     

The Effects of Effort Monitoring With Proctor Notification on Test-Taking Engagement,Test Performance,and Validity

When we administer educational achievement tests, we want to be confident that the resulting scores validly indicate what the test takers know and can do. However, if the test is perceived as low stakes by the test taker, disengaged test taking sometimes occurs, which poses a serious threat to score validity. When computer-based tests are used, disengagement can be detected through occurrences of rapid-guessing behavior. This empirical study investigated the impact of a new effort monitoring feature that can detect rapid guessing, as it occurs, and notify proctors that a test taker has become disengaged. The results showed that, after a proctor notification was triggered, test-taking engagement tended to increase, test performance improved, and test scores exhibited higher convergent validation evidence. The findings of this study provide validation evidence that this innovative testing feature can decrease disengaged test taking.     

III. ATTACHMENT AND EMOTIONAL DEVELOPMENT IN INSTITUTIONAL CARE: CHARACTERISTICS AND CATCH UP

Attachment has been assessed in the extreme environment of orphanages, but an important issue to be addressed in this chapter is whether in addition to standard assessment procedures, such as the Strange Situation, the lack of a specific attachment in some institutionalized children should be taken into account given the limits to the development of stable relationships in institutionalized care. In addition, this chapter discusses disinhibited or indiscriminately friendly behavior that is often seen in institutionalized children. Enhanced caregiving quality alone appears to be insufficient to diminish indiscriminate behavior, at least in some children, as evidenced by the persistence of indiscriminate behavior in children adopted out of institutions into adoptive families. We suggest that the etiology and function of indiscriminate, “friendly” behavior may be different for institutionalized versus not‐institutionalized children. In the first case it may reflect a distortion or disruption of early attachment relationships; in the latter case it is likely to result from the lack of expected input in the form of contingent interactions with a stable caregiver in early life. We try to delineate infant and caregiver characteristics that are associated with secure attachment in institutional settings, given the inevitable fact that large numbers of infants worldwide are being raised, and will be raised, in contexts of institutional care. We conclude that much further study is needed of the development of children's attachments following adoption out of an institutional setting.     

Nameability supports rule-based category learning in children and adults

The present study tested the hypothesis that verbal labels support category induction by providing compact hypotheses. Ninety-seven 4- to 6-year-old children (M = 63.2 months; 46 female, 51 male; 77% White, 8% more than one race, 4% Asian, and 3% Black; tested 2018) and 90 adults (M = 20.1 years; 70 female, 20 male) in the Midwestern United States learned novel categories with features that were easy (e.g., “red”) or difficult (e.g., “mauve”) to name. Adults (d = 1.06) and—to a lesser extent—children (d = 0.57; final training block) learned categories composed of more nameable features better. Children's knowledge of difficult-to-name color words predicted their learning for categories with difficult-to-name features. Rule-based category learning may be supported by the emerging ability to form verbal hypotheses.     

Challenges in Enacting Core Practices in Language Teacher Education: A Self-Study

In this study, I explore my practices as a teacher educator in one course both before and after returning to the K–12 classroom to teach secondary language learners for one academic year. By examining the intersection of self-study and practice-based teacher education, I illustrate how I used self-study as a mechanism for innovation and change and focus on the challenges I encountered in implementing the use of practice-based education in my work as a teacher educator. Qualitative data analysis revealed that in redesigning my approach to my course, I stopped short of my goals to make the course more practice-centered. Although I provided students with many opportunities to practice planning, I did not provide enough focused opportunities to practice implementation and to participate in giving and receiving feedback. I learned that engaging teachers in practice-based teaching requires teacher educators to be both specific and deliberate in setting their own purposes for establishing the centrality of practice in their courses and to explain these clearly to teacher candidates. Further work in which teacher educators study their use of practice-based pedagogy would benefit from using a self-study lens. Other researchers are urged to add to the limited body of research about the use of practice-based pedagogy with teachers of language learners, particularly English language learners.     

Collaborative learning: A memorable model

Abstract

Reform movements envision schools that will involve greater levels of cooperation and collaboration. Collaborative learning strategies provide a powerful mechanism not only to address affective goals in education but also to enhance students’ cognitive development; to deepen their understanding of concepts; and to press them to examine, articulate, and elaborate their ideas with greater clarity and rigor. Unless teachers have effective means to manage the complex problem solving involved in implementing collaborative learning strategies, the rich possibilities offered will not be realized. This paper proposes a five‐part conceptual framework to guide teachers decision making in order to capitalize on these powerful strategies. The framework incorporates a “G” mnemonic to make the elements memorable.
