This multiple paper dissertation addressed several issues revolving around the estimation of effect sizes for computer-based scaffolding in problem-centered STEM education. STEM jobs are outpacing all other jobs and STEM workers are expected to solve complex problems. However, students often struggle with complex problem activities. Research on…

Collaborative learning designs, such as problem-based learning (PBL), have the potential to help students build valuable team-based professional skills needed for life after schooling within higher-educational settings (Desimone, 2009; Savery, 2006); however, motivating students to work together to successfully achieve outcomes often proves…

Sociological and cultural analysts have noted the reticence of public secondary schooling to recognize and build academic activities around the participatory culture in which adolescents are so readily involved (Jenkins, Purushotma, Weigel, Clinton & Robison, 2009).

The purpose of this qualitative study was to gather data on the scaffolding a facilitator developed and used for learners during a Problem-Based Learning (PBL) setting. The study explored how the learners developed their ability to share their understanding and current knowledge by solving the presented real-world problem through investigation…

Computer technology is used as a mediational tool to support collaborative instructional methods. Computer support offers a platform for collaboration with the goal of scaffolding students' understanding, providing increased agency to the student for their own learning, and motivating students, as participants in a PBL process. In online PBL,…
