Investigated the effect of two variables on remedial students' performance in freshman composition: attending a remedial grammar course, and receiving tutoring at a skills development center. Found that tutoring had a significant positive impact on students, but that the grammar course had a negative effect. (ARH)

Describes a laboratory exercise in which acid dissociation constants and molecular weights are extracted from sample data and the sample is identified. Emphasizes accurate volumetric work while bringing to practice the concepts of acid-base equilibria, activity coefficients, and thermodynamic constants. (CW)

Describes an application of potentiometry to the determination of acidic and basic compounds in household cleaners in chemistry instruction. Discusses procedures and results of this experiment. (CW)

Relates the story of the arrival of a new instructor at a community college and his introduction to contemporary composition methods, wittily parodying both writing process jargon and computer jargon. (NKA)

This description of an ideal school computer laboratory focuses on physical characteristics and includes guidelines for floors, walls, ceilings, doors, wiring, seating configurations, and furniture. (LRW)

Investigates the effects of using scientific apparatus versus household objects on the accuracy of primary school children in a simple titration exercise. Indicates no significant difference between the accuracy obtained using the two types of apparatus at the beginning, but improved performance for children using scientific apparatus by the end.…

Describes a quantitative experiment designed to demonstrate buffer action and the measurement of buffer capacity. Discusses how to make acetate buffers, determine their buffer capacity, plot the capacity/pH curve, and interpret the data obtained. (TW)

Describes a college developmental reading laboratory model using peer tutors to provide training in comprehension study skills. Reports the results of a study evaluating the impact of training on student performance from the perspective of the participants. (MM)

Discusses a national program designed to encourage the integration of writing more fully into the college curriculum. Addresses the opportunities for improving writing instruction by focusing on the laboratory reports done by students. (TW)

To improve the testing of students' skills in performing laboratory experiments, 92 Israeli high school physics teachers participated in the development of a list of weighted laboratory skills. Sensory-motor coordination was found to be a significant measured factor. Factors affecting reliability were also noted. (GDC)

Cites reasons why Penicillium claviforme is an exceptionally good species for ultraviolet induced mutation experiments. Provides a set of laboratory instructions for teachers and students. Includes a discussion section. (ML)

Discusses the use of specific reactions of metabolic pathways to make measurements in the laboratory. Describes an adaptation of an experiment used in undergraduate biochemistry laboratories involving the induction of an enzyme in E. coli, as well as its partial purification and characterization. (TW)

Reviews software packages by providing extensive descriptions and discussions of their strengths and weaknesses. Software reviewed include (1) "VISIFROG: Vertebrate Anatomy" (grade seven-adult); (2) "Fraction Bars Computer Program" (grades three to six) and (3) four telecommunications utilities. (JN)

Presents a laboratory experiment which determines critical temperature and density of carbon dioxide. Discusses critical point and provides equations to estimate liquid volume fraction. Analyzes experimental results in terms of variables. (JM)

Challenges language educators to use the computer wisely, as a tool for more effective learning of language, which is so crucial to the building of world-wide bridges of understanding in this age of economic interdependence and nuclear threat. (Author/SED)
