Today, science educators accept that digital literacy has been one of the key concepts for science teachers in terms of creating meaningful science learning environments. Although there are many research attempts investigating digital literacy in science teacher education literature, the interrelations of this concept to cognitive and…

Although the literature contains many examples of extensive professional development (PD) programs, most science teachers experience only a few hours of PD each year. To address this reality, alternative PD delivery tools need to be examined. Since the mid-1990s, video cases have emerged as a flexible form of PD where in-service teachers can…

This paper briefly reports the outcomes of an action research inquiry on the use of blogs, MS PowerPoint [PPT], and the Internet as learning tools with a science class of sixth graders for project-based learning. Multiple sources of data were essential to triangulate the key findings articulated in this paper. Corresponding to previous studies,…

Chemistry instructors in teaching laboratories provide expert modeling of techniques and cognitive processes and provide assistance to enrolled students that may be described as scaffolding interaction. Such student support is particularly essential in laboratories taught with an inquiry-based curriculum. In a teaching laboratory with a high…

We present results of an investigation of preservice secondary mathematics and science teachers' conceptions of project-based instruction (PBI) and their enactments of PBI in apprentice (student) teaching. We evaluated their thinking and implementations within a composite framework based on the work of education researchers. We analyzed survey…

The concept map tool set forth by Novak and colleagues is underutilized in education. A meta-analysis has encouraged teachers to make extensive use of concept mapping, and researchers have advocated computer-based concept mapping applications that exploit hyperlink technology. Through an NSF sponsored geosciences education grant, middle and…

The Exploring Florida Science project goals were: (1) increasing content knowledge of secondary science teachers, specifically in topics that are important to the future of the state, and (2) providing secondary science students with digital media for use in project-based learning. A team of instructional designers, educators, scientists, web…
