Enzymes are nature's catalysts, mediating chemical processes in living systems. The study of enzyme function and mechanism includes defining the maximum catalytic rate and affinity for substrate/s (among other factors), referred to as enzyme kinetics. Enzyme kinetics is a staple of biochemistry curricula and other disciplines, from molecular and…

The "Technology Outlook for Latin American Higher Education 2013-2018: An NMC Horizon Project Regional Analysis" was released as a collaborative effort between the New Media Consortium (NMC), the Centro Superior para la Enseñanza Virtual (CSEV), and Virtual Educa. This report -- published both in Spanish and English -- will inform…

Discusses the characteristics and development of a computer simulation laboratory for educational administration research at the University of Wisconsin at Madison, and reviews an experimental study performed at the laboratory on stress in decision-making. Explores how simulations provide researchers access to experimental conditions unavailable…

Design of computer circuits used to be a pencil and paper task followed by laboratory tests, but logic circuit design can now be done in half the time as the engineer accesses a program which simulates the behavior of real digital circuits, and does all the wiring and testing on his computer screen. A simulated laboratory in digital logic has been…

Discussed is the history and elements of the personal computer. Its uses as a laboratory assistant and generic toolkit for mathematical analysis and modeling are included. The future of the personal computer in research is addressed. (KR)

The "Technology Outlook Australian Tertiary Education 2013-2018: An NMC Horizon Project Regional Analysis" reflects a collaborative research effort between the New Media Consortium (NMC) and Open Universities Australia to help inform Australian educational leaders about significant developments in technologies supporting teaching,…

The target of difficulty of the Educational Technology Center (ETC) Heat and Temperature Group is basic thermal physics, particularly the differentiation between heat and temperature. High school teachers often find that thermal concepts are very difficult for their students to master and attribute students' difficulties at least in part to the…

Describes the style of design of computer simulations developed by Computer Assisted Teaching Unit at Queen Mary College with reference to user interface, input and initialization, input data vetting, effective display screen use, graphical results presentation, and need for hard copy. Procedures and problems relating to academic involvement are…

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 of 87 veterinary medical students at Auburn University tests the effectiveness and student acceptance of interactive videodisc as an alternative to animal experimentation and other traditional teaching methods in analyzing canine cardiovascular sounds. Results of the questionnaire used are presented, and benefits of interactive video…

Research was undertaken to investigate various methods of presentation of a computer based science simulation as it related to student content knowledge of the simulation concepts. Three treatment groups of sixth grade students were used in the study: (1) two students per computer interacting with the simulation; (2) a total class presentation of…

Information on student learning in terms of amount and efficiency when using interactive video instead of traditional laboratory methods as well as questions on the use of live animals for instruction is provided. The methods, results, discussion, and summary are included. (KR)

Reports on a study designed to determine the relative effectiveness of different instructional approaches on chemistry laboratory achievement. Investigated differences in achievement in spectrophotometry among college freshmen who received either traditional, learning cycle, or computer simulation instruction. Results indicated that students…

Discusses production and evaluation of interactive computer-assisted videodisc laboratory tutorial simulations for use in prelaboratory instruction and as laboratory experiment replacement in an undergraduate chemistry course. Student performance on laboratory reports and tests was significantly better for students who utilized the simulations.…

Discussed are seven computer programs: (1) a computer graphics experiment for organic chemistry laboratory; (2) a gel filtration simulation; (3) judging spelling correctness; (4) interfacing the TLC548 ADC; (5) a digitizing circuit for the Apple II game port; (6) a chemical information base; and (7) an IBM PC article database.
