Reports on a naturalistic study conducted with 24 low-achieving high school biology students that determined how the teacher and students used two computer-based videodisk programs, a print-based activity, and a dissection laboratory to learn about frog anatomy and to conduct a frog dissection. Future research is suggested. (Contains 14…

Data collected for the International Association for the Evaluation of Educational Achievement (1989) within U.S. secondary schools revealed that computer usage more than doubled from 1985. Discussed are the regular and systematic uses of computers in the classroom and laboratories, the types of software used, and the goals for teachers using…

Qualitatively studied the transfer of skills and perceptions developed in microteaching to the student teaching experience (n=17) and any changes in these skills and concerns throughout the duration of student teaching (n=6). Analysis of the data indicated 17 categories of subjects' perceptions, concerns, etc. (PR)

Examines instructional plans of four beginning teachers preparing to teach familiar and unfamiliar topics in biology. This analysis constitutes one level of a multimethodological study of effects of teacher subject-matter knowledge on high school science teaching. Among conclusions are that teacher's choice of instructional strategies affects…

Discusses results of a study of high school students that was conducted to determine, through measures of student achievement, the educational effectiveness of interactive satellite delivery compared with traditional classroom instruction in anatomy and physiology and to compare the attitudes toward anatomy and physiology of distance students and…

This study documented the teaching practices of 2 exemplary biology teachers of grades 11 and 12 by means of an interpretive research methodology. Teaching practices are identified that may be considered exemplary and worthy of attention and analysis by other science teachers and science teacher educators. (PR)

Presents a course outline for the study of biotechnology at the high school or college level. The outline includes definitions, a history, and the vocabulary of biotechnology. Presents a science experiment to analyze the effects of restriction enzymes on DNA. (MDH)

The development of scientific explorations in schools and a framework for their assessment within the context of Britain's Graded Assessment in Science Project (GASP) scheme is described. The criteria for assessing the planning, implementing, concluding, and evaluating of explorations are provided. (KR)

Twenty science experiments are presented. Topics include recombinant DNA, physiology, nucleophiles, reactivity series, molar volume of gases, spreadsheets in chemistry, hydrogen bonding, composite materials, radioactive decay, magnetism, speed, charged particles, compression waves, heat transfer, Ursa Major, balloons, current, and expansion of…

Three commercial products for data acquisition with the Macintosh computer, known by the trade names of LabVIEW, Analog Connection WorkBench, and MacLab were reviewed and compared, on the basis of actual trials, for their suitability in physiological and biological teaching laboratories. Suggestions for using these software packages are provided.…

Investigated is a reader's ability to comprehend written text that is highly novel with few semantic cues. The theoretical perspective, assessment theory, materials and methods, and the results of this study are discussed. (KR)

Explains how computer database technology can be used in the herbarium and be a useful aid in teaching botany and plant taxonomy. (PR)

Presents a simple model that can help students think about evolution and better understand the gradualist and punctuationist macroevolution approaches. The model also improves instruction for concepts of mutation, selection, fitness, extinction, and origin of life. Describes an IBM computer program for instruction in these areas. (PR)

Describes the selection and implementation of an authentic assessment model for evaluating students' science laboratory knowledge and skills. Provides sample problems and a scoring form for the performance-based science laboratory test. (MDH)

Describes an introductory meteorology course for nonacademic high school students. The course is made hands-on by the use of an educational software program offered by Accu-Weather. The program contains a meteorology database and instructional modules. (PR)
