Computer-based scaffolding provides temporary support that enables students to participate in and become more proficient at complex skills like problem solving, argumentation, and evaluation. While meta-analyses have addressed between-subject differences on cognitive outcomes resulting from scaffolding, none has addressed within-subject gains. This leaves much quantitative scaffolding literature not covered by existing meta-analyses. To address this gap, this study used Bayesian network meta-analysis to synthesize within-subjects (pre–post) differences resulting from scaffolding in 56 studies. We generated the posterior distribution using 20,000 Markov Chain Monte Carlo samples. Scaffolding has a consistently strong effect across student populations, STEM (science, technology, engineering, and mathematics) …

Masters Theses & Specialist Projects
The purpose of this study was to identify if and how STEM (Science, Technology, Engineering, Math) lessons help student progress toward achieving benchmarks in AASL (American Association of School Librarians) 21st Century Learner Standards. This study was conducted in the library media center with 48 kindergarten students participating. The researcher taught mini-lessons for the AASL Standards prior to students participating in the STEM activities. The data were collected on 23 benchmarks included in the AASL Standards. Students were rated on these Standards as beginning, progressing, or achieving. Data analysis indicated that the STEM lessons were an effective means for providing …

Learning about circuitry by connecting a battery, light bulb, and wires is a common activity in many science classrooms. In this paper, we expand students’ learning about circuitry with electronic textiles, which use conductive thread instead of wires and sewable LEDs instead of lightbulbs, by integrating programming sensor inputs and light outputs and examining how the two domains interact.We implemented an electronic textiles unit with 23 high school students ages 16–17 years who learned how to craft and code circuits with the LilyPad Arduino, an electronic textile construction kit. Our analyses not only confirm significant increases in students’ understanding of …
