Today's children grow up surrounded by computers. They observe them, interact with them and, as a consequence, start forming conceptions of how they work and what they can do. Any constructivist approach to learning requires that we gain an understanding of such preconceived ideas and beliefs in order to use computers as learning tools in an…

Despite the promise of technology in education, many practicing teachers face several challenges when trying to effectively integrate technology into their classroom instruction. Additionally, while national statistics cite a remarkable improvement in access to computer technology tools in schools, teacher surveys show consistent declines in the…

The study examines the professional development of junior-high-school teachers participating in the Israeli "Katom" (Computer for Every Class, Student and Teacher) Program, begun in 2004. A three-circle support and training model was developed for teachers' professional development. The first circle applies to all teachers in the…

While the knowledge economy has reshaped the world, schools lag behind in producing appropriate learning for this social change. Science education needs to prepare students for a future world in which multiple representations are the norm and adults are required to "think like scientists." Location-based augmented reality games offer an…

Presents key points of an on-line conference discussion and integrates them with information from the literature. Key points included: computer as a tool for learning, study, research, and communication; hardware, software, computing concepts, and other teaching concerns; and the appropriate place for chemistry computer-usage instruction. (45…

Two examples of the interaction between computer technology and assessment are described: a tool-based knowledge representation approach to assess content understanding and a team problem-solving task involving negotiation. The examples serve as the context for the exploration of validity, equity, and utility. (LZ)

The use of computers in science assessment is examined for six considerations: (1) purpose of computer use in assessment; (2) value of program evaluation models; (3) possible harmful side effects of assessment; (4) nature of imbedded questions; (5) definition of treatment; and (6) computers and the classroom context. (LZ)

This paper reports on teachers' perceptions of the educational affordances of a handheld application called Participatory Simulations. It presents evidence from five cases representing each of the populations who work with these computational tools. Evidence across multiple data sources yield similar results to previous research evaluations of…

Suggests that computer and related technologies as tools for teaching, learning, and assessment are neither gender neutral nor benign in effect. Examines computers, equity, and access issues, computers as a technology, and the implications for computer-based assessment. (LZ)

Reviews seven computer applications for science assessment including conventional, multiple-choice, constructed-response, adaptive, figural response, simulation, and an emerging approach to performance assessment termed solution pathway analysis. Virtually all computer-based testing systems are found to improve the quality and efficiency of record…

Suggests that, based on a theory of situated learning, assessment must emphasize process as much as product. Several assessment examples are given, including a computer-based planning assistant for a mathematics and science video, suggestions for computer-based portfolio assessment, and speculations about embedded assessment of virtual situations.…

Discusses the potential role of technology in evaluating learning outcomes in large-scale, widespread science assessments. Describes current state-of-the-art techniques in this area and looks at the past and future uses of technology in large-scale science assessments. (LZ)

Gives descriptions of how performance assessment tasks are linked to science curriculum objectives, along with criteria for and examples of performance assessment tasks. Describes the role that computers and related technology can play in problem-based performance assessment. (LZ)

Despite a rise in the use of handheld computers in classrooms, meaningful learning with personal digital assistant (PDA) technology remains poorly studied. This article reports results from an evaluation of customized handheld data collection software, the BioKIDS Sequence, which was used during an 8-week biodiversity curriculum unit by 5th and…

Two methods of assessing student learning of a hands-on instructional unit are compared. One method involves manipulation of concrete materials, and the other method involves manipulation of icons on a computer to solve an electric circuits problem. Sixth-grade students in an inquiry-based science program completed both assignments. (LZ)
