Six biology teachers and 90 students participated in this study. Results indicate that teachers can be trained to use a systematic questioning technique, trained teachers can employ the technique in classroom settings, and students taught by the technique achieve higher and retain knowledge longer than those in control groups.

An instructional program based on expert-novice differences in experimental problem-solving performance was taught to grade six students (N=265). Performance was assessed with multiple-choice and open-ended measures of specific transfer. Between-group comparisons using pretest scores as covariate showed treatment condition students consistently…

Advocates the seminar/discussion method of teaching to facilitate comprehension/interpretation of scientific facts, with the understanding that acquiring facts is a prerequisite. Points out the increased burden on teacher time resulting from increased teacher-student contact and reiterates the motto "Theory guides, experiment decides," as the…

Documented training and educational activities of preservice elementary education majors (N=20) to determine what (if any) aspects of their science training contribute to developing the apprehension elementary teachers have toward science, science education, and science instruction. Results, conclusions, and implications are reported from the…

Ascertained influence of an intervention in development of operational seriation/transitivity in kindergarten/first-grade children (N=60) who initially failed to demonstrate ability to do seriation/transitivity problems. Seriation of size was also studied. Results, interpreted in context of Piaget's equilibrium theory, indicated advancement toward…

Advantages and disadvantages of microcomputer use are noted. Computer managed and assisted instruction are discussed, followed by guidelines for software and microcomputer selection. Uses of CAI in the science curriculum are noted: simulation, modeling, gaming, drills, and tutorials. Finally, a project to disseminate instructional materials in…

Two areas of research were explored in this meta-analysis: comparison of inductive versus deductive approaches and use of advance organizers. The study involved 128 characteristics for 39 studies spanning the period from 1957 through 1980. Coding variables included 57 concerned with treatment features and 12 with outcome attributes. (Author/JN)

Discusses drill/practice programs and computer simulations. Also provides a chart comparing programs available through the Minnesota Educational Computing Consortium (MECC). Included in the chart are title, grade level(s), content, skills required to complete program, potential of program to be integrated into regular curriculum, values…

Compared formal science scope/sequence with curriculum as it was taught in Little Rock (Arkansas) classrooms. Elementary teachers (N=126) were given a list of 273 concepts and asked if a topic was a significant part of their instruction and how much time was spent teaching it. Results are reported and discussed. (JN)

Suggests general chemistry, organic chemistry, and biochemistry content for a two-semester, health-related, chemistry course sequence. Indicates that basic principles should be emphasized and that (when appropriate) these principles should be discussed with applications to health care. Other issues related to chemistry for health-related programs…

Summarizes 19 literature sources identifying road-killed vertebrates and frequency of kill by numbers. Examples of how these animals can be incorporated into curricula (integrating biology, society, people, and values) are given, followed by an illustrated example of how a road-killed raccoon's skull demonstrated a human/wildlife interaction prior…

Describes rationale for and advantages of using programed study aids in solving organic chemistry problems. Includes examples of these programed, multi-step aids which provide leading questions, factual information, and in some cases, the logical thinking required to arrive at correct (although short) answer. (JN)

Based on a model of local curriculum development, but incorporating the ideas first expressed by Goodlad in establishing a league of co-operating schools for the improvement of learning, this curriculum development project successfully infused the study of technology into the science courses of several British secondary schools. (RM)

Suggests cooperative learning projects if only one microcomputer is available for a large class. An example of such a project using a program dealing with correlating sedimentary rock layers through cross-sectional analysis is described. Instructional strategies and academic objectives of the three-module program are included. (JN)

Discusses merits of using sigma-pi model of ethylene as a teaching aid in introductory organic chemistry. The nonmathematical treatment of sigma-pi bonding is then extended to such phenomena as conjugation, hyperconjugation, Markovnikoff addition, aromaticity, and aromatic substitution. (SK)
