Virtual, mixed, and augmented reality, termed "extended reality," or XR, have great potential for classroom-based learning. Yet many questions about the use and widespread adoption of these emerging technologies remain. To share insights, opportunities, and challenges, the Joan Ganz Cooney Center at Sesame Workshop and the XR Association…

The problem of this study was to develop, validate, and establish the reliability of a computer simulation which would: (1) distinguish between concrete and formal thinking patterns related to control of variables; (2) be easily administered to a class of secondary school age subjects; (3) preserve the interactive aspects of the Piagetian task;…

This document reports on the first year of the STACI (Systems Thinking and Curriculum Innovation) project, a two-year project which is examining the cognitive demands and consequences of using the STELLA (Structural Thinking Experimental Learning Laboratory with Animation) software to teach systems thinking, content knowledge, and problem solving.…

An integral part of the curriculum in introductory biology courses is the study of Mendelian genetics. Results from genetics learning studies and needs assessments demonstrated the need for additional intensive research in biology education and genetics learning. There exists a lack of detailed information describing reasoning patterns and…

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.

Describes a video monitoring technique for detailed analysis of student use of computer-based learning programs which produces a synchronized record of computer output and student use; a study concerned with developing computer-based learning programs in chemistry which utilizes the technique; and advantages and disadvantages of the technique.…

In order to evaluate standard setting procedures, apart from the more commonly applied approach of simply comparing the derived standards or failure rates across various techniques, this study investigated the errors of classification associated with the contrasting groups procedures. Monte Carlo simulations were employed to produce…

This three-part paper describes the development of a software program called "The Growth Curve of Microorganisms" for a tenth-grade biology class. Designed to improve students' cognitive skills, the program enables them to investigate, through computer simulations, the impact upon the growth curve of a population of three variables: temperature,…

Though item bias statistics are widely recommended for use in test development and analysis, problems arise in their interpretation. This research evaluates logistic test models and computer simulation methods for providing a frame of reference for interpreting item bias statistics. Specifically, the intent was to produce simulated sampling…

Describes five computer software packages; four for MS-DOS Systems and one for Apple II. Included are SPEC20, an interactive simulation of a Bausch and Lomb Spectronic-20; a database for laboratory chemicals and programs for visualizing Boltzmann-like distributions, orbital plot for the hydrogen atom and molecular orbital theory.

Presents thinking-aloud protocols from secondary pupils solving arithmetic story and geometrical problems and analyzes their protocols by using interpretation models founded on a general problem-solving model. A word problem solving simulation is also used to further explicate processes pupils use to solve mathematical tasks. (Author/MBR)

This paper examines the effect of using a systems thinking approach in existing secondary school curricula to teach content-specific knowledge as well as general problem solving skills, and the effect of using STELLA (Structural Thinking Experimental Learning Laboratory with Animation), a simulation-modeling software program, as a tool by which to…

This is the second of two reports on the first year activities and results of the Systems Thinking and Curriculum Innovation Project (STACI), a two-year project which is examining the cognitive demands and consequences of using the STELLA (Structural Thinking Experimental Learning Laboratory with Animation) software to teach systems thinking,…

Reviews two studies whose results indicate that students who share computers develop better work skills and social attitudes. One study, using eighth graders and a computer simulation, measured performance on worksheets and final exams. The second study used language learning via computer-assisted instruction to compare results on achievement…
