This dissertation focuses on three manuscripts all related to bolstering science achievement through recommendations from the National Research Council (NRC) regarding the teaching and learning of science. The manuscripts address meeting the NRC's call to incorporate curriculum and assessment that lead to more in-depth knowledge that can be…

Pedagogic Conversational Agents are computer applications that can interact with students in natural language. They have been used with satisfactory results on the instruction of several domains. The authors believe that they could also be useful for the instruction of Secondary Physics and Chemistry Education. Therefore, in this paper, the…

Interactive computer-marked assignments (iCMAs) are in use on a range of Science Faculty level 1 modules at the Open University UK, alongside tutor-marked assignments, for summative and formative purposes. They are also used diagnostically to help prospective students to make an appropriate choice of starting point. iCMAs have been very well…

Acquisition of conceptual knowledge is a central aim in science education. In this study we monitored an interdisciplinary hypermedia assisted learning unit on hibernation and thermodynamics based on cooperative learning. We used concept mapping for the assessment, applying a pre-test/post-test design. In our study, 106 9th graders cooperated by…

Reports on the administration and grading of automated tests in five successive semesters of a course in genetics and evolution. Students showed a gain in learning. Suggests that gains in learning will vary with discipline, teaching technique, and student background. (Author/MM)

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)

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 use of a bank of about 9,000 test items in a computer-assisted instructional program at Adelaide University (South Australia). Describes the program and outlines the steps in producing an instructional program. (TW)

Describes a strategy for using computer technology to save time when checking the data and calculations of students. Provides information regarding software and hardware used. (YP)

Describes an evaluation program which is aimed at providing well-designed, comprehensive, and objective tests to a specific category of engineering students. Involves the use of a computerized statistical analysis. Provides recommendations for organizing such an activity. (TW)

Describes the practical workup of a multiple choice examination system in electrical engineering. Discusses some of the pedagogical advantages obtained by statistical handling of the data. Provides some examples of items. (TW)

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)

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)
