This study investigated the experience of and effect created by a team sport and coaching intervention upon the self-concept of male school students (age: 12-16; n = 129) from diverse backgrounds. A convergent parallel mixed-method design was used to compare and relate a questionnaire study and an interview study in a quasi-experimental design,…

My dissertation is a pre-mid-post-test, quantitative research design, including surveys and written assessments, to answer these research questions: 1. How do students' science mindset vary over time when engaged in science inquiry activities? Is there a difference between male and female students? 2. Is there a relationship between 7th grade…

Empirical findings have repeatedly demonstrated that students' motivation decreases over the course of secondary education. This decline in learning motivation is one of the top challenges nowadays and is relevant for policy, as well as research and practice. Taking this educational challenge into account, the chapter targets the following…

In the L2 Motivational Self System (L2MSS) motivation is conceptualized to be generated by discomfort associated with the learner's experience of a discrepancy between their current L2 self, and their ideal L2 self.

Extant research indicates culturally relevant literature (CRL) is linked to increased reading comprehension and interest in reading for Latinx students as well as other student groups. Current research also shows CRL can support home literacy instruction, facilitate writing instruction, foster sociopolitical awareness, underpin behavior…

We examined whether German adolescents who participated in an adapted 8-week school-based intervention, the "Identity Project," reported greater changes in heritage and global identities and perceptions of classroom cultural climate. We used a longitudinal, wait-list control design pooling eight classrooms across the school years of…

Agentic orientation, critical thinking (CrT) and taking the fourth-person perspective (4PP) are described as teachable attainments.

A life-issue scenario was used to pre- and…

Black and Latinx youth are situated in a maladaptive discriminatory context in the United States; however, prosociality may be one way that youth can promote their own positive development in the face of these experiences. We examined the longitudinal associations between discrimination and prosociality among 380 Black and Latinx early adolescents…

To address the needs of middle school students who experience difficulty with reading, students are often placed in reading intervention programs to improve literacy skills. This study explores the question: in what ways do students successfully and unsuccessfully use self-initiated comprehension strategies in their efforts to engage with…

Cross-national studies consistently reveal that bullying is a pervasive problem in schools and associated with a multitude of deleterious outcomes.
