The study explores how a complexity approach empowers science learning. A complexity approach represents systems as many interacting entities. The construct of micro-macro compatibility is introduced, the degree of similarity between behaviors at the micro- and macro-levels of the system. Seventh-grade students' learning about gases was studied…

Drawing upon the literature in computational modeling, multivariable reasoning, and causal attribution, this study aims at characterizing multivariable reasoning practices in computational modeling and revealing the nature of understanding about multivariable causality. We recruited two freshmen, two sophomores, two juniors, two seniors, four…

Describes studies designed to examine the instrumentation used to assess both graphing abilities and the impact of microcomputer-based laboratories (MBL) on students' graphing abilities. Results suggest that numerous disparities between the results of multiple-choice and free response instruments. The analysis also revealed that the impact of MBL…

Suggests that the construction and reconstruction of meanings by learners requires that they actively seek to integrate new knowledge with knowledge already in their cognitive structure. Concept mapping has been used effectively to aid meaningful learning with resulting modification of student's knowledge structures. Asserts that new computer…

Investigates performance outcomes based on different goal orientations by using a computer support environment (SCI-WISE) designed for learning and doing inquiry-based science projects. Uses two versions of SCI-WISE software and systems based partly on the theoretical framework of levels of agency and goal orientation. (Contains 16 references.)…

Describes a design for a computer-based environment to assist students in conducting dialectical activities of constructing, comparing, and evaluating arguments for competing scientific theories. (ZWH)

Researchers and practitioners have attempted to identify technologies that support students' scientific understanding, activities and support practices that facilitate students' inquiry processes, and methods to sustain technology-enhanced innovations in everyday science classrooms. The purpose of this paper is to examine the findings and…

Reports on a case study that examines the teaching and learning impact of technology from the perspective of students participating in a long-term study of technology implementation. The study is situated within the context of the Technology Enhanced Secondary Science Instruction (TESSI) project. Contains 65 references. (DDR)

Investigated the appropriateness of microcomputer-based laboratories (MBLs) for elementary school students. Reports that children expanded their repertoire of graph-making and interpreting skills and MBLs supported scientific inquiry for and by the children. (28 references) (Author/JRH)

Holding the premise that the development of expertise is a continuous process, this study concerns expert models and modeling processes associated with a modeling tool called Model-It. Five advanced Ph.D. students in environmental engineering and public health used Model-It to create and test models of water quality. Using "think aloud" technique…

Describes a model of inservice education designed to increase opportunities for teacher interaction and the availability of instructional resources. Emphasizes teacher control. Discusses workshops, school visits, and computer conferencing. Presents an analysis of the participation of teachers in computer conferencing following the workshop. (CW)

Compared attitudes toward computer use and achievement in biology for three groups of Nigerian students (n=64): (1) working alone with computer; (2) working in groups of three on the computer; (3) and a control group that received normal instruction (lecture). Students in the second group had the highest scores on attitude. No significant…
