This dissertation focuses on three manuscripts all related to bolstering science achievement through recommendations from the National Research Council (NRC) regarding the teaching and learning of science. The manuscripts address meeting the NRC's call to incorporate curriculum and assessment that lead to more in-depth knowledge that can be…

With the large demand for technology workers all around the world, more people are learning programming. Studies show that human tutoring is the most effective way to learn for novice programmers. However, problems such as the inaccessibility to physical classes, prohibitive costs, and the lack of educators may limit students' opportunities to…

Cross-community collaboration which expands community members' interaction to a larger social scale plays a crucial role in increasing information exchange and extending inquiry learning. This dissertation uses a design-based research approach which aims at testing a multi-level emergence design in multiple learning communities. This design serves…

The purpose of this multiple case design-based research study was to determine what elements were needed to assist two higher education instructors inexperienced in designing and teaching a blended learning course to successfully create and implement it, to document the instructors' perceptions about their first experience of teaching a blended…

Integrated STEM education comprises an exploration of the interconnections between science, technology, engineering and mathematics in order to reflect on how each discipline operates within real world contexts. Students benefit from the integrated STEM approach because it values students' real-life experiences and hands-on applications that…

Research in team science suggests strategies for addressing difficulties that groups face when working together. This dissertation examines how student teams work in project based learning (PBL) environments, with the goal of creating strategies and technology to improve collaboration. The challenge of working in such a group is that the members…

This quantitative study examined the perceptions of Alabama community college students and faculty toward Web-enhanced courses and the impact of these courses on the educational experience as defined by Chickering and Gamson's "Seven Principles for Good Practice in Undergraduate Education," an empirically based model. Secondarily, the…

Among educational researchers and practitioners, there is a growing interest in employing computer games for pedagogical purposes. The present research integrated a technology education class and a science class where 5th graders learned about environmental issues by designing games that involved environmental concepts. The purposes of this study…
