Impact Of Scaffolding Characteristics And Study Quality On Learner Outcomes In Stem Education: A Meta-Analysis, Brian Belland, Andrew Walker, M. Olsen, Heather Leary
Impact Of Scaffolding Characteristics And Study Quality On Learner Outcomes In Stem Education: A Meta-Analysis, Brian Belland, Andrew Walker, M. Olsen, Heather Leary
Heather Leary, Ph.D.
This paper employs meta-analysis to determine the impact of scaffold characteristics and study and assessment instrument quality on cognitive student outcomes in science, technology, engineering, and mathematics education at the K-12, college, graduate, and adult levels. Studies were coded for necessary information for effect size calculation, contextual information, threats to internal and external validity, and assessment instrument validity and reliability. Results indicate (a) scaffolding positively impacts student learning (g = 0.53), (b) studies with zero threats to internal validity had lower effect sizes than studies with two threats, (c) studies with one threat to external validity had higher effect sizes …
Self-Directed Learning In Problem-Based Learning: A Meta-Analysis, Heather Leary, Andrew Walker, Brett E. Shelton
Self-Directed Learning In Problem-Based Learning: A Meta-Analysis, Heather Leary, Andrew Walker, Brett E. Shelton
Heather Leary, Ph.D.
This paper presents a meta-analysis focused on self-directed learning in problem-based learning when compared with a traditional learning approach. A total of 75 outcomes from 38 studies were used in the analysis which resulted in a statistically significant overall medium effect size of g = 0.45, favoring problem-based learning. Subgroup analyses conducted focused on four aspects of self-directed learning. Both personal autonomy (g = 0.51, z(47) = 6.4, p = 0.01) and independent pursuit of learning (g = 0.66, z(2) = 3.49, p = 0.01) report statistically significant positive effect sizes. Three of eight disciplines reported statistically significant effect sizes …
Integrating Technology And Problem-Based Learning: A Mixed Methods Study Of Two Teacher Professional Development Designs, Andrew Walker, Mimi Recker, M. Brooke Robertshaw, Jeffrey Osen, Heather Leary, Lei Ye, Linda Sellers
Integrating Technology And Problem-Based Learning: A Mixed Methods Study Of Two Teacher Professional Development Designs, Andrew Walker, Mimi Recker, M. Brooke Robertshaw, Jeffrey Osen, Heather Leary, Lei Ye, Linda Sellers

This article describes two consecutive enactments of technology-oriented teacher professional development designs, aimed at helping teachers find high-quality online learning resources and use them in designing effective problem-based learning (PBL) activities for their students. To align with current professional development prescriptions, in the first enactment, teachers learned PBL design skills concurrently with technology skills. Following aspects of design-based research, the professional development theory, participant feedback, and results from the first enactment informed the design of the second. In this second enactment, technology skills were separated and presented prior to learning about PBL. Results from a mixed-methods study of impact indicated …
