Provides a yearly summary of research and graduate study activities at most United States and several Canadian engineering colleges. Provides officers of the institution; number of faculty, graduate students, and undergraduate students; extension centers; doctoral research areas; budgeted research; and degree requirements. (MVL)

Described is a study which was conducted as an exploratory assessment of science reviewers' perceptions for the future of science education. Arrives at interpretations for identified categories of computers and high technology, science curriculum, teacher education, training, certification, standards, teaching methods, and materials. (RT)

Describes activities which demonstrate the abundance of organisms living underground. Provides outlined directions, lists of materials, and a soil ecosystem transparency for delving into the properties of soil. (RT)

Studies whether traditional drafting equipment (TRAD) or computer aided drafting equipment (CAD) is more effective. Proposes that students using only CAD can learn principles of drafting as well as students using only TRAD. Reports no significant difference either on achievement or attitude. (MVL)

States that quantitative modelling allows teachers to concentrate more on qualitative understanding. Suggests the main benefits as (1) repetitive calculations are reduced allowing greater attention to be focused on underlying models; (2) more "what if" models can be tested; and (3) a wider variety of data can be used to test models. (MVL)

Discussed is the 1986 NAEP data on understanding and using basic science facts. Suggests using observing, measuring, and hypothesis testing as supplements to traditional instructional methods. The use of this technique is urged for Black, Hispanic, and female students to compensate for the lack of outside experiences noted in the NAEP findings.…
