There have been many practical obstacles for teachers to implement evidence-based educational technology, especially in STEM classrooms. By implementing learning principles related to Cognitive Load Theory, we developed an innovative Technology-Assisted Guided Learning (TAGL) approach and its web-based instructional tool, combining expertise from…

In each of three studies, students using computer assisted instruction for supplemental drill and practice in a first organic chemistry course performed consistently higher than control students on sections of the course examinations related to the content of the programs. (AL)

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…

Examines a number of factors that might influence performance in a college laboratory chemistry course. Compares the achievement and time for students doing a simulated or a laboratory experiment. Tries to identify differences in performance for students of different aptitude and possible interaction between types of experiment and student…

The purpose of this study was to analyze the effectiveness of long-term, tutorial-type computer assisted instruction (CAI) in high school chemistry. Analysis showed scores of non-CAI students significantly higher than the CAI group. However, CAI students learner material faster. (PS)

Determined the effect of computer assisted instruction (CAI) materials on college students' attitudes toward computers and chemistry. Includes the finding that the attitude of women toward computers was improved by using CAI.

Examines the effect of computer-assisted instruction (CAI) on students' understanding of chemical formulas and mole concept, and their attitudes toward chemistry and CAI. Reports that students who used the CAI accompanied with lectures scored significantly higher and demonstrated significant improvement in attitudes compared to the control group…

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)

Evaluates the attributes of a microcomputer software package as a supplement to chemistry instruction. Reports higher scores among the students in a control group. Discovers no significant interaction between treatment and development stage. Discusses several implications for further research. Provides the General Chemistry Test and error analysis…

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 present study makes use of the capabilities of computerized environments to enable simultaneous display of molecular representations that correspond to observations at the macroscopic level. This study questions the immediate and long-term effects of using a multimedia instructional unit that integrates the macroscopic, symbolic, and molecular…
