A Meta-Analysis Of Middle School Science Engagement, Leanna B. Aker Jan 2016

A Meta-Analysis Of Middle School Science Engagement, Leanna B. Aker

Education Dissertations

Researchers and educational practitioners have long been concerned with declines in science engagement reported by students as they transition into the middle school setting. Though the operationalization of engagement is still nascent, an emerging consensus on a three-faceted model of student engagement has recently emerged in the research literature (Fredricks, Blumenfeld, & Paris, 2004). Thus, a synthesis of existing primary research of early adolescents’ science engagement under this emerging conceptualization was warranted. The results of this meta-analysis indicate that instructional methods, class characteristics and competence predictors had the strongest relationship with self-reported science engagement in early adolescence. These predictors also show ...


A Meta-Analysis Of The Effects Of Problem- And Project-Based Learning On Academic Achievement In Grades 6-12 Populations, Kimberly J. Jensen Aug 2015

A Meta-Analysis Of The Effects Of Problem- And Project-Based Learning On Academic Achievement In Grades 6-12 Populations, Kimberly J. Jensen

Education Dissertations

Researchers and proponents of problem- and project-based learning (PBL) indicate that PBL as a curriculum and instruction approach (Savery, 2006; Schmidt, Loyens, Van Gog, & Paas, 2007) provides an effective way for teachers to respond to students’ needs, provides opportunities for students to actively engage in and take responsibility for learning by engaging in meaningful and relevant work, and provides students opportunities to directly apply their knowledge and skills (Hmelo-Silver & DeSimone, 2013; McCombs, 2010; Parker et al., 2011). Although primary research within secondary (6-12) contexts indicated that problem-and project based learning (PBL) is often superior to traditional, lecture-based instruction (Mergendoller, Maxwell, & Bellisimo, 2006; Wirkala & Kuhn, 2011) and meta-analyses at the post-secondary level indicated that PBL is at par with or superior to traditional, lecture-based instruction (Dochy, Segers, Van den Bossche, & Gijbels, 2003; Vernon & Blake, 1993; Walker & Leary, 2009), a synthesized and quantified exploration of the strength of relationship between PBL and academic achievement within middle high school student populations (Grades 6-12) was needed. The results in this meta-analysis indicate that overall, PBL students outperformed traditionally instructed students, g = 0.54, on content and skills exams across academic subject types and grade levels. Analysis of the funnel plot suggests publication bias; however, an adjustment of the mean effect using Duval and Tweedie’s (2000) Trim and Fill rendered a similar summary effect of g = 0.50. Although the mean summary effect is relatively robust, effect sizes varied depending on subject area and specific types of ...


Effects Of Scaffolding Higher Order Thinking Questions On Reader Self-Efficacy And Critical Thinking Of Sixth Grade Students, Jason L. Mckinnon May 2012

Effects Of Scaffolding Higher Order Thinking Questions On Reader Self-Efficacy And Critical Thinking Of Sixth Grade Students, Jason L. Mckinnon

Education Dissertations

This study examined the potential benefits of instructional strategies that scaffold the development of higher order thinking (HOT) questions on reader self-efficacy and critical thinking. Another goal of this study aimed to investigate the relationship between reader self-efficacy and critical thinking. The explicit instruction of HOT questions involves four steps: (a) selecting Bloom’s revised taxonomy to identify effective question strands; (b) assessing HOT questions use through the Classroom Practice Record (CPR); (c) implementing strategy instruction focusing on explicit scaffolding techniques and allowing time to practice the implementation of strategies during assigned lessons for a period of eight weeks; and ...
