Maintaining learning engagement throughout adolescence is critical for long-term academic success. This research sought to understand the role of metacognition and motivation in predicting adolescents' engagement in math learning over time. In two longitudinal studies with 2,325 and 207 adolescents (ages 11-15), metacognitive skills, interest, and…

Despite the growing body of studies on collocation learning in SLA research, there are hardly any studies taking the perspective of the individual learner or studies that have examined the effect of individual differences. This study--a qualitative component of a mixed-methods longitudinal project--presents an in-depth exploration of the intro-…

The motivation to learn a third language (L3) has received increasing attention in research, especially with regard to how it evolves dynamically during the learning process. Underpinned by the L2 Motivational Self System [Dörnyei, Z. 2005. "The Psychology of the Language Learner: Individual Differences in Second Language Acquisition."…

This dissertation investigates the longitudinal development of Chinese language proficiency among students in a Chinese as a Foreign Language (CFL) Flagship Program at an American public university from 2014 to 2024. Using Bayesian multilevel regression models, this study assesses the trajectories of listening, speaking, and reading proficiency…

. This research examined longitudinal trajectories of Korean students' motivation to learn science using groupbased trajectory modeling (GBTM). The changes in five motivational constructs were focused in this research: self-efficacy, intrinsic motivation, grade motivation, self-determination, and career motivation. In addition, the relationship…

As the United States experiences greater income inequality, more and more students experience an early science achievement gap. This study tested several competing theoretical models of early science achievement with a longitudinal sample of 14,624 children who were followed from kindergarten entry to the end of 1st grade. To understand why and…

The present study provides an in-depth, longitudinal account of an undergraduate student's L2 discourse socialization in an academic exchange program in Canada. By invoking Rogoff's (1995) notion of participatory appropriation, this qualitative case study examined an L2 student's task-related strategies and performance as they evolved over time in…

This article reports on the study of differential change trajectories for early childhood approaches to learning. A large sample (N = 2,152) of Head Start children was followed through prekindergarten, kindergarten, and first grade. Classroom learning behaviors were assessed by teachers through the Preschool Learning Behaviors Scale twice in Head…

This is a mix methods follow-up study in which we reconfirm the findings from an earlier study [Vedder-Weiss & Fortus [2011] "Journal of Research in Science Teaching, 48(2)", 199-216]. The findings indicate that adolescents' declining motivation to learn science, which was found in many previous studies [Galton [2009] "Moving to…

This article presents results from a longitudinal study following a cohort of medical students. Semistructured interviews are conducted every year, in which the students tell about their experiences learning medicine, their daily life, and their social activities in relation to university. The aim of the study is to analyze how medical students…

This paper proposes a model of learning dynamics and learning energy, one that analyzes learning systems scientifically. This model makes response to the learner action by means of some equations relating to learning dynamics, learning energy, learning speed, learning force, and learning acceleration, which is analogous to the notion of Newtonian…
