Teacher evaluation is currently a major policy issue at all levels of the K-12 system driven in large part by current US Department of Education requirements. The main objective of this study is to explore the patterns of relationship between observational scores and value-added measures of teacher performance in math classrooms and the variation…

This study explored the relationships among the components of the Arizona Department of Education's new teacher evaluation model, with a particular focus on the extent to which ratings from the state model's teacher observation instrument differentiated higher and lower performance. The study used teacher-level evaluation data collected by the…

Scientific sense-making is a process in which theory and evidence are brought into coordination. This work examines the conditions for the development of scientific sense-making in fifth and sixth grade classroom science lessons. Classroom activities that were structured as a series of presentations are compared with activities structured more as…

Examines features of electronic mail discourse among sixth-grade students and their teachers. Highlights include structures of the sixth-grade classrooms; common characteristics of and differences between electronic and face-to-face communication; metacommunication; consistency with print genres; hierarchy; and the potential of electronic mail in…

Discusses the integration of technology into the curriculum and how to design an interactive technological learning environment based on the concept of scientific sense-making. Highlights include the importance of sense-making in science education and an experiment on curriculum design for a fifth- to sixth-grade unit on seasonal change. (Contains…

Describes a prototype for the use of local area network (LAN) technology in a sixth grade earth science curriculum. Classroom activities that focus on cooperative small group learning are discussed, coordinated investigations as a framework for scientific activities in the classroom are explained, and possible future work with LAN environments is…

Arguing that the development of a notion of sense-making is of critical importance to improving science learning, this paper examines science teaching in four Boston (Massachusetts)-area classrooms that participated in an experiment on ways of integrating technology into a sixth-grade science curriculum on the earth's seasons. The task of the…
