Mobile devices have become increasingly more visible within classrooms and informal learning spaces. The purpose of this dissertation is to examine the impact of mobile learning (m-learning) tools to support student learning during teacher-led field trips. Specifically, the research questions for this study are: (a) What conditions affect student…

Two functionally-indicated choice-making interventions were implemented by a classroom teacher to determine the effects on the percentage of task completion, accuracy, and classroom disruption for 9 sixth through eighth grade participants with emotional and behavioral disorders in a residential math classroom using a reversal design. Results…

Consistent with a Diathesis × Stress model, it was hypothesized that anxious solitude (individual vulnerability) and the middle school transition (environmental stress) would jointly predict peer exclusion and victimization trajectories. Youth (N = 688) were followed from 3rd through 7th grade, with the middle school transition in 6th grade.…

This paper presents results of a research study focusing on the analysis, comparison, and description of students' attitudes towards the teaching of mathematics lessons presented in a foreign language (English) using the Content and Language Integrated Learning (CLIL) method in three elementary schools. It also highlights the difference between…

Substantial evidence suggests that rumination is an important vulnerability factor for adolescent depression. Despite this, few studies have examined environmental risk factors that might lead to rumination and, subsequently, depression in adolescence. This study examined the hypothesis that an adverse family environment is a risk factor for…

Interactions between conceptual and procedural knowledge influence the development of mathematical competencies. However, after decades of research, these interrelations are still under debate, and empirical results are inconclusive. The authors point out a source of these problems. Different kinds of knowledge and competencies only show up…

Few studies have documented the literacy activities in an after-school setting of affluent early adolescents assigned to remedial reading. This may be because these students are not considered to be at risk of academic failure. The out-of-school literacy activities of 3 sixth-grade students were examined in this qualitative research. Multiple data…

Exhibits in informal science institutions, like science centers and museums, are often designed to help people learn, but research showing the immediate impact of experiences with exhibits on understanding is limited. This dissertation tested the hypothesis that the value of first-hand experience with an exhibit is not necessarily in its immediate…
