This dissertation focuses on three manuscripts all related to bolstering science achievement through recommendations from the National Research Council (NRC) regarding the teaching and learning of science. The manuscripts address meeting the NRC's call to incorporate curriculum and assessment that lead to more in-depth knowledge that can be…

Computer vision (CV) is a subfield of artificial intelligence (AI) that trains computers to understand our visual world based on digital images. There are many successful applications of CV including face and hand gesture detection, weather recording, smart farming, and self-driving cars. Recent advances in computer vision with machine learning…

By comparing two-dimensional (2D) chemical animations designed for computer's desktop with three-dimensional (3D) chemical animations designed for the full immersive virtual reality environment CAVE[TM] we studied how virtual reality environments could raise student's interest and motivation for learning. By using the 3ds max[TM], we can visualize…

Empirical research evaluating the effectiveness of learning objects is noticeably absent. No formal research has been done on the use of learning objects in secondary schools. The purpose of this study was to evaluate the use of learning objects by high school students. The evaluation metric used to assess benefits and quality of learning objects…

Discusses a study that assessed how students felt about computers and how they perceived computers performed as instructional tools. A majority of the tested students indicated that the computer was a useful tool in their chemistry classes, that the labs were realistic, but computer grading should not be used. (ML)

Examines the relative effectiveness of guided versus unguided computer-based instruction with regard to regular instruction in improving content knowledge and process skills among students with low and high chemistry achievement levels. The effectiveness of computer-based instruction increases when learning is supported by teacher-directed…

Describes the use of batch-oriented computing as the basis for reintroducing homework problems as a teaching tool in beginning chemistry instruction. Stems from and expands upon a system used in a university setting that produces, delivers, grades, and keeps records for homework problems. (DDR)

Describes two experiments in college chemistry which use microcomputers. One experiment deals with chemical oscillations, while the other involves colorimeter titration with laser excitation and computer-interfaced endpoint detection. (TW)

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…

Provides a review of both the Apple and IBM versions of ENZPACK, a software package which is designed to assist in the teaching of enzyme kinetics in courses where this topic is treated in some depth. (TW)

Describes a multimedia course in engineering developed to serve course materials to students in a more realistic form so that they will better understand the relevance of the material. Defines multimedia, discusses the advantages of multimedia presentation of course material, and provides details of the tools used in this project. (DDR)

Describes two general spreadsheet templates to carry out all types of one-equation chemical equilibrium calculations encountered by students in undergraduate chemistry courses. Algorithms, templates, macros, and representative examples are presented to illustrate the approach. (PR)

Describes two computer assisted tutorials, one on acid ionization constants (Ka), and the other on solubility product constants (Ksp). Discusses framework to be used in writing computer assisted instruction programs. Lists topics covered in the programs. (MVL)

Demonstrates the importance of Real-Time, Sensor-Based (RTSB) computing and how it can be easily and effectively integrated into university student laboratories. Describes the experimental processes, the process instrumentation and process-computer interface, the computer and communications systems, and typical software. Provides much technical…

Described is how spreadsheet and problem solver microcomputer programs may assist students in performing mathematical calculations. Discussed is the application of the equation solver "MathCAD" to various areas in the undergraduate curriculum. (KR)
