This study aimed to identify profiles of achievement goal orientations and transitions between these profiles among adolescents from different socioeconomic backgrounds before and during the COVID-19 pandemic. A sample of 1268 adolescents (51.7% females; M[subscript age] = 14.87; SD[subscript age] = 0.39) participated in four waves of data…

This study examined the within- and between-day variability of time-segmented sedentary behavior (SB), light physical activity (LPA), and moderate-to-vigorous physical activity (MVPA) in adolescents. The sample comprised 154 adolescents (11-16 years old) from two public schools in Florianópolis, Brazil. The proportion of time spent in SB, LPA, and…

While a number of factors have already been shown to impact variations in graduation rates among students in Canada, there is little research examining the changing impact of these factors on Ontario students' secondary education completion over time. This research draws on data from two Grade 9 cohorts (2006 and 2011) from the Toronto District…

Building on recommendations from several of the articles in the special section on conscientiousness in the June 2014 issue of "Developmental Psychology," the present study tested predictions from the interactionist model (IM) of socioeconomic influences on individual development. In an approach consistent with the idea of cumulative…

Considering well-documented difficulties in mastering ecology concepts and system thinking, the aim of the study was to examine 9th graders' understanding of the complex, multilevel, systemic construct of feeding relations, nested within a larger system of a live model. Fifty students interacted with the model and manipulated a variable within it…

Background: This study examined differences in students' time spent in physical activity (PA) across secondary schools in rural, suburban, and urban environments and identified the environment-level factors associated with these between school differences in students' PA. Methods: Multilevel linear regression analyses were used to examine the…

Mixed-aged (MA) classes are a common phenomenon around the world. In Sweden, these types of classes increased rapidly during the 1980s and 1990s, despite the fact that existing empirical support for MA classes is weak. In this paper, the effect of attending an MA class during grades 4-6 on students' cognitive skills is estimated. Using a unique…

Performance-based activities and creative projects with technology that focus on Shakespeare's language are powerful developmental tools for students to express and extend thoughts and feelings from their lives. Shakespeare becomes a toy chest and a toolset that allows students to live in situations they never could and to express language they…

Super (1990) proposed that the psychological determinants of career development attitudes are time perspective, self-esteem, and causal attributions. The present study analyzed the effects of these determinants on the career development attitudes of 320 students from grade 9 and 300 students from grade 12. The analysis of the data using structural…

The types of difficulties associated with career attitudes were studied using Super's model of career maturity (1990) in a group of 620 Portuguese students from grades 9 and 12. A cluster analysis identified four styles with different patterns of association between time perspective, attributional beliefs, self-esteem and career attitudes. The…

In this article, Fairbanks, Crooks, and Ariail followed Esme Martinez, a Spanish-speaking Latina, from the sixth grade to the eleventh grade, focusing on her perspectives of schooling and her shifting identities related to home, school, friendships, and future. Drawing on the construct of artifacts, a sociohistorical concept that understands…

When the authors taught Walter Dean Myers's postmodern young adult novel "Monster" to ninth graders, they assumed the students would like the text, as its format and style resemble that of popular television crime shows. The authors also assumed the students would be savvy readers of the text, capable of understanding and integrating postmodern…

This study's purpose is to examine the existing school climate literature in an attempt to constitute its definition from a historical context and to create a valid and reliable student-reported school climate instrument. Five historically common school climate domains and five measurement tools were identified, combined, and previewed by the…

This study describes English language learner (ELL) student enrollment and achievement trends in Delaware public schools from 2002/03 to 2008/09. Two research questions guide this study: (1) How did the enrollment of ELL students in Delaware public schools change between 2002/03 and 2008/09?; and (2) How did performance (the percentage scoring at…
