Chemical bonding is central to explaining many phenomena. Research in chemical education and the Framework for K-12 Science Education (the "Framework") argue for new approaches to learning chemical bonding grounded in (1) using ideas of the balance of electric forces and energy minimization to explain bond formation, (2) using learning…

The Next Generation Science Standards (NGSS) have spurred renewed interest in the epistemologies that students adopt as they engage in science practices. One framework for characterizing students' epistemologies is the "epistemologies in practice" framework (Berland et al. (2016), "Journal of Research in Science Teaching,"…

It is widely recognized that we need to prepare students to think with data. This study investigates student interactions with digital data graphs and seeks to identify what might prompt them to shift toward using their graphs as thinking tools in the authentic activity of doing science. Drawing from video screencast data of three small groups…

The development of three-dimensional learning among all K-12 student demographics remains a prominent goal for the field of science education. However, substantial research in science teacher education for urban populations showcases hurdles to overcome in order to achieve this goal, particularly for elementary teachers. Research shows that urban…

The aim of this experimental study was to compare learning outcomes of students using a simulation alone (simulation environment) with outcomes of those using a simulation in parallel with real circuits (combination environment) in the domain of electricity, and to explore how learning outcomes in these environments are mediated by implicit (only…

A study of 61 high school biology students found that Interactive Video Disk (IVD) simulation was as effective as actual frog dissection in promoting student learning of frog anatomy and dissection procedures. When used as a preparation for dissection, IVD simulation helped students perform better dissections and learn more from doing dissections.…

This study investigated what constitutes exploratory learning and what effects instructional support measures have on it. Among the conclusions were that students were reluctant to apply learning processes that are considered characteristic for exploratory learning. Students had problems with the process, especially with the process of generating…

Reports on a study designed to investigate how the use of computer assisted instruction (CAI) tutorial programs, incorporating advance organizers and involving various sizes of groups of subjects, would affect achievement scores, retention scores, and rates of learning. (TW)

This study used a microcomputer program which diagnosed and remediated an alternative conception of velocity. Results show computer simulations are credible representations of reality and that the remedial part of the program produces significant conceptual changes in students holding the alternative conception.

Students' views of science as static, mixed, and dynamic are characterized. The relationship between views of science and acquisition of integrated understanding of thermodynamics is examined. Students with dynamic views acquired more integrated understanding than those with static views. Data were collected from 153 middle school students who…

This study analyzes the impact of an integrated sensory model within a thermal equilibrium visualization. We hypothesized that this intervention would not only help students revise their disruptive experientially supported ideas about why objects feel hot or cold, but also increase their understanding of thermal equilibrium. The analysis…

The question of how children solve force and motion problems in computer simulations without explicit knowledge of the underlying physics was investigated. Keystroke sequences made by children were saved and analyzed, and children were interviewed to understand their perception of the relationship between keyboard input and on-screen action. (CW)

The problem-solving behaviors and genetics concepts employed by experts and novices during interaction with the computer simulation CATLAB, were examined. Thirteen subjects (3 experts and 10 novices) investigated a common hypothesis on a specific genetic trait during the computer activity. Using naturalistic research methods, general patterns of…

The purpose of this study was to examine the effects of three instructional methods and conceptual systems orientation on achievement in a freshman general chemistry laboratory course. Traditional approach, learning cycle, and computer simulations are discussed. (KR)

This study investigated the effectiveness of computer simulations for enhancing the problem solving skills of high school students. Summaries of three related studies are presented. Results indicate that the computerized simulations enabled students to master the objectives of a biology course as effectively as traditional methods. (ML)
