This mixed methods study (Creswell, 2008) was designed to test the influence of collaborative testing on learning using a quasi-experimental approach. This study used a modified embedded mixed method design in which the qualitative and quantitative data, associated with the secondary questions, provided a supportive role in a study based primarily…

In the following pages, we examine some common methodological challenges in educational technology research and highlight new data collection approaches using examples from the literature and our own work. Given that surveys and questionnaires remain widespread and dominant tools across nearly all studies of educational technology, we first…

Piezoelectric actuators (or piezoactuators) are known for their nanoresolution and high-speed positioning capabilities. Therefore, they are used in scanning probe microscopes and in the design of innovative surgical tools and biomedical devices. The expected growth of engineering jobs in the nano- and bio-related fields, in which piezoactuators…

In the first part of this dissertation, I document wiki usage in U.S. K-12 settings by analyzing data on a representative sample drawn from a population of nearly 180,000 wikis. My research group, which I lead and managed, measured the opportunities wikis provide for students to develop 21st century skills such as expert thinking, complex…

Today's important geo-spatial technologies, GIS (Geographic Information Systems), GPS (Global Positioning Systems) and Google Earth have been widely used in geography education. Transferring spatially oriented data taken by GPS to the GIS and Google Earth has provided great benefits in terms of showing the usage of spatial technologies for field…

This dissertation was designed to examine and assess the effectiveness of the ClassScape formative assessment tool on the planning, implementation, and evaluation of instruction at a rural middle school in western North Carolina. The teachers had the ClassScape program for 3 years, but were not using the program to plan future instruction. The…

The purpose of this study is to explore pre-service chemistry teachers' images of science teaching in their future classrooms. Also, association between instructional style, gender, and desire to be a teacher was explored. Sixty six pre-service chemistry teachers from three public universities participated in the data collection for this study. A…

This mixed-methods investigation compared the relative impacts of instructional approach and context of nature of science instruction on preservice elementary teachers' understandings. The sample consisted of 75 preservice teachers enrolled in four sections of an elementary science methods course. Independent variables included instructional…

The Mathematics in the Kimberley Project is a three-year research and development project that focuses on mathematical pedagogy in remote Aboriginal community schools. The research team has regularly reported on the project at MERGA (Mathematics Education Research Group of Australasia) conferences, and in this symposium the participants evaluate…

Lesson study, a form of school-based professional development widely practiced in Japan, has gained popularity in the United States over the last two decades. However, research on its effectiveness has been limited in scope, typically conducted shortly after the conclusion of the professional learning and focused primarily on the practices of…

This is a case study of two elementary teachers' development and change over time with respect to fostering a math-talk classroom. One teacher was beginning the process of National Board Certification and the other teacher became certified two years prior. A critical component of the certification process is reflection on one's teaching practice.…

This study aims to share English language practitioners' reflections on the adaptation of teaching methods and materials during the pre-validation period of the European Language Portfolio (ELP). In order to achieve this aim, a high school was selected as the scope of research, since it has started to adapt the English language teaching…

Background: Despite considerable investment in UK government initiatives (e.g., the Physical Education School Sport [PESS] plan) aimed at improving the delivery and quality of physical education (PE) in primary schools, many remaining problems have been highlighted (e.g., facilities; staff training). It is suggested that the head teacher (school…

Data-driven decision-making (DDDM) is a system of teaching and management practices that gets better information about students into the hands of classroom teachers. This article discusses the five major elements: (1) good baseline data; (2) measurable instructional goals; (3) frequent formative assessment; (4) professional learning communities;…

Purpose: International service-learning (ISL) is popular in higher education, and many physical therapy educational programs are adding ISL opportunities to their curricula because doing so aligns with student interest and the increasingly global nature of the profession. The faculty leading these experiences have not been studied. Nearly all…
