Chemical Understanding and Graphing Skills in an Honors Case-Based Computerized Chemistry Laboratory Environment: The Value of Bidirectional Visual and Textual Representations
Peer reviewed Peer reviewed
Direct linkDirect link
Dori, Yehudit J.; Sasson, Irit – Journal of Research in Science Teaching, 2008
The case-based computerized laboratory (CCL) is a chemistry learning environment that integrates computerized experiments with emphasis on scientific inquiry and comprehension of case studies. The research objective was to investigate chemical understanding and graphing skills of high school honors students via bidirectional visual and textual…

Teaching the Design and Interpretation of Graphs through Computer-Aided Graphical Data Analysis.
Peer reviewed Peer reviewed
Jackson, David F.; And Others – Journal of Research in Science Teaching, 1993
Describes a project where computer-assisted graphical data analyses were introduced to inner-city high school students with weak math and science backgrounds. Provides examples of performance of students on open-ended problem-solving tasks. (PR)

The Impact of Microcomputer-Based Labs on Children's Ability to Interpret Graphs.
Peer reviewed Peer reviewed
Mokros, Janice R.; Tinker, Robert F. – Journal of Research in Science Teaching, 1987
Reports the results of an in-depth examination of middle school children's graphing skills and misconceptions. Also discusses a study in which students learned graphing skills through microcomputer-based laboratory (MBL). (ML)

Teaching Thermodynamics to Middle School Students: What Are Appropriate Cognitive Demands?
Peer reviewed Peer reviewed
Linn, Marcia C.; Songer, Nancy Butler – Journal of Research in Science Teaching, 1991
When comparing performances across four versions of Computer as Lab Partner curriculum, increases in understanding were found when students predicted outcomes and reconciled results, and students used a heat-flow model of thermodynamics to integrate their experimental results. Argued is that curriculum must explicitly motivate students to…

A Protocol Analysis of the Influence of Technology on Students' Actions, Verbal Commentary, and Thought Processes During the Performance of Acid-Base Titrations.
Peer reviewed Peer reviewed
Nakhleh, Mary B.; Krajcik, Joseph S. – Journal of Research in Science Teaching, 1993
From an analysis of 14 secondary student's actions and thought processes, it was found that technology's level of information affected the focus of student observations. The microcomputer group focused primarily on the graph while other groups exhibited multiple foci. The discussion data also reveal that students have three main ideas about how…

The Effect of Real-Time Laboratory Graphing on Learning Graphic Representations of Distance and Velocity.
Peer reviewed Peer reviewed
Brasell, Heather – Journal of Research in Science Teaching, 1987
Discusses a study which assessed the effect of a brief kinematics unit on: (1) students' ability to translate between a physical event and the graphic representation of it, and; (2) the effect of real-time on graphing skills. Reports the success of the use of a microcomputer-based laboratory with graphing velocity and distance. (ML)

Evaluations of Science Laboratory Data: The Role of Computer-Presented Information.
Peer reviewed Peer reviewed
Nachmias, Rafi; Linn, Marcia C. – Journal of Research in Science Teaching, 1987
Examines (1) how students evaluate information obtained in the science laboratory; (2) the effects of use of microcomputer-based laboratory; and, (3) the effects of explicit instruction on critical evaluation skills. Discusses results in terms of students' propensity to accept incorrect graphs and in terms of the effect of the enhanced instruction…
