Examining Teacher Technology Use: Implications for Preservice and Inservice Teacher Preparation

As access to computer-based technology in schools and classrooms increases, greater emphasis has been placed on preparing teachers to use technology for instructional purposes. Survey data collected from 2,894 teachers in 22 Massachusetts districts were analyzed to examine the extent to which technology is used in and out of the classroom for instructional purposes. In addition to defining six specific categories of instructional use of technology, this study provides evidence that teachers generally use technology more for preparation and communication than for delivering instruction or assigning learning activities that require the use of technology. Important differences, however, were found among teachers who were new to the field compared with their more experienced colleagues. Although new teachers reported higher levels of comfort with technology and use it more for preparation, more experienced teachers report using technology more often in the classroom when delivering instruction or having students engage in learning activities.

A Study of the Effectiveness of the Louisiana Algebra I Online Course

Abstract Student enrollment in K–12 online learning programs showed a tenfold expansion in the years between 2002 and 2005. Despite increased implementation to fulfill critical local needs, there is very little evidence-based research available to inform education leaders’ decisions relating to these initiatives. To address the important question of whether online learning can be as effective as traditional face-to-face learning, this research presents the findings from a quasi-experimental design implemented to examine the effect of the Louisiana Algebra I Online initiative on student outcomes. The findings presented suggest that the Louisiana Algebra I Online model is a viable online model for providing effective Algebra I instruction.

Examining the Relationship Between Students' Understanding of the Nature of Models and Conceptual Learning in Biology, Physics, and Chemistry

This research addresses high school students’ understandings of the nature of models, and their interaction with model‐based software in three science domains, namely, biology, physics, and chemistry. Data from 736 high school students’ understandings of models were collected using the Students’ Understanding of Models in Science (SUMS) survey as part of a large‐scale, longitudinal study in the context of technology‐based curricular units in each of the three science domains. The results of ANOVA and regression analyses showed that there were differences in students’ pre‐test understandings of models across the three domains, and that higher post‐test scores were associated with having engaged in a greater number of curricular activities, but only in the chemistry domain. The analyses also showed that the relationships between the pre‐test understanding of models subscales scores and post‐test content knowledge varied across domains. Some implications are discussed with regard to how students’ understanding of the nature of models can be promoted.

Concerns, Considerations, and New Ideas for Data Collection and Research in Educational Technology Studies.

Abstract 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 discuss the background and limitations of how researchers have traditionally used surveys to define and measure technology use (as well as other variables and outcomes). Through this discussion, we introduce our own work with a visual analog “sliding” scale as an example of a new approach to survey design and data collection that capitalizes on the technology resources increasingly available in schools. Next, we highlight other challenges and opportunities inherent in the study of educational technology, including the potential for computer adaptive surveying, and discuss the critical importance of aligning outcome measures with the technological innovation, concerns with computer-based versus paper-based measures of achievement, and the need to consider the hierarchical structure of educational data in the analysis of data for evaluating the impact of technology interventions.

Impact of Online Professional Development on Teacher Quality and Student Achievement in Fifth Grade Mathematics.

Abstract Despite the ever-increasing number of online professional development (OPD) programs, relatively few studies have been conducted to examine the efficacy of such programs for teachers and students. This manuscript presents findings from an impact study of OPD courses infractions, algebraic thinking, and measurement on 79 fifth grade teachers’ pedagogical content knowledge and pedagogical practices as well as their students’ mathematics achievement. The OPD courses were offered one course per semester for three semesters, and each course comprised 1 week of orientation and 6 weeks of course content. Overall, teachers participated in more than approximately 70 hours of OPD. The research findings showed that teachers who had been randomly assigned to the experimental group had significantly greater gains in scores for pedagogical content knowledge and pedagogical practices than teachers in the control group. Nevertheless, the positive changes in teacher outcomes did not translate to any meaningful differences in students’ mathematics achievement.

The effectiveness of concept mapping and retrieval practice as learning strategies in an undergraduate physiology course.

Concept mapping and retrieval practice are both educational methods that have separately been reported to provide significant benefits for learning in diverse settings. Concept mapping involves diagramming a hierarchical representation of relationships between distinct pieces of information, whereas retrieval practice involves retrieving information that was previously coded into memory. The relative benefits of these two methods have never been tested against each other in a classroom setting. Our study was designed to investigate whether or not concept mapping or retrieval practice produced a significant learning benefit in an undergraduate physiology course as measured by exam performance and, if so, was the benefit of one method significantly greater than the other. We found that there was a trend toward increased exam scores for the retrieval practice group compared with both the control group and concept mapping group, and that trend achieved statistical significance for one of the four module exams in the course. We also found that women performed statistically better than men on the module exam that contained a substantial amount of material relating to female reproductive physiology.
