Over the past decade, investment in technology for schools has increased at a dramatic rate. Although policy makers are eager to understand the ways in which technology use in schools is affecting student learning, we believe that a critical preliminary step toward assessing the impacts of technology on teaching and learning requires the examination of the varied uses of technology in schools as well as the contexts that are likely to affect the use of technology in the classroom as a teaching and learning tool. Previous research examining technology use has focused on teacher characteristics and has neglected to explore the potentially alterable, organizational characteristics that may be affecting the adoption and use of technology in the classroom. In light of this argument and using survey data collected from 1490 elementary classroom teachers in 96 schools in 22 Massachusetts districts, this research examines how technology is being used by elementary school teachers, and examines the school and district organizational characteristics that are associated with increased use of technology as a teaching and learning tool. In addition to examining technology-use as a multi-faceted construct, using multilevel regression techniques this study provides evidence that schools’ organizational characteristics are associated with teachers’ use of technology in the classroom. Organizational characteristics such as districts’ and schools’ leadership practices and emphasis on technology, the type and amount of technology-related professional development available to teachers, as well as the amount of technology-related restrictive policies in place were found to be associated with the four measures of teachers’ use of technology examined in this study. Individual teacher characteristics such as constructivist beliefs, higher confidence using technology and positive beliefs about the efficacy of technology were each found to be associated with increased use of technology in the classroom.

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.

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.

This longitudinal study tested for changes in how students used and were called homophobic epithets as they progressed through high school. Boys used and were called these epithets with increased frequency over time, whereas girls reported decreases on both. Distinct gender socialization processes may contribute to these different pattems for boys and girls. Also, variability in students' own bullying and victimization across assessments corresponded with variability in their use of homophobic epithets and being called these epithets. These findings capture the dynamic yet significantly covarying nature of these behaviors, adding support for the link between bullying, victimization, and homophobic language. Further, students who reported overall higher tendencies to bully or to be victimized than others also reported more often using and being called homophobic epithets during their first semester of high school. Findings are discussed in terms of implications for research on the dynamics of this behavior, psychological and academic implications, and implications for educational policies and intervention programs.
