Authors discuss "the scientific method" and assert that laboratory scientists ask questions but seldom state formal hypotheses to be answered by controlled experiments. Authors suggest that experimental results should not be viewed as fact, and students should not be required to memorize the steps of the scientific method. (PR)

Suggests that teachers should consider which questions to ask as a part of instructional preparation. To ensure that diversity and critical thinking are involved, a teacher should use a taxonomy for a template when writing questions. Presents and discusses Bloom's taxonomy, Gagne's levels of learning, and a taxonomy for general science process…

Fifteen mother-daughter pairs from incestuous family involving male caretaker were matched to 16 mother-daughter pairs from nonclinical families. Found that mothers from incest group reported greater amounts of family life stress, had more negative perceptions of their problem-solving appraisal, and reported more communication difficulties than…

Investigated was the presence and role of cue words in word problems found in three mathematics textbooks series. The methodology and results of the study are presented. Lists of cue words for grades 3-6 are provided. (CW)

Investigated the effect of computer programs that require the use of spatial skills on third and fourth graders' spatial ability. Students who used a software program that required rotation of objects scored better than other students on a measure of figural classification, but not on a measure of object rotation. (BC)

An exercise that gives students a chance to use the equations of state for both an ideal gas and for an adiabatic process in determining the points at which heat flow reverses direction and at which the working substance reaches its maximum temperature is demonstrated. (KR)

The Group Embedded Figures Test and a teaching style inventory administered to 25 preservice agriculture teachers showed (1) field-independent learners achieved higher scores in methods courses; (2) those preferring more sensitive teaching styles achieved higher microteaching scores; (3) preference for the inclusion teaching style did not…

Although traditional discipline procedures (expulsion, time-out rooms, suspensions, and scolding) teach students to depend on authority figures to resolve conflicts, the Peacemaker Program teaches children how to mediate disputes and negotiate solutions themselves. To regulate their own behavior, students must have opportunities to make decisions…

Presents a public-key cryptosystem application to introduce students to several topics in discrete mathematics. A computer algorithms using recursive methods is presented to solve a problem in which one person wants to send a coded message to a second person while keeping the message secret from a third person. (MDH)

Why children under 10 years do not use their mathematics knowledge to build a shortcut strategy to solve inversion problems was studied with 88 elementary school students in Munich (Germany). Most could use the shortcut but did so only when it did not compete with a more familiar strategy. (SLD)

Discussion of virtual reality (VR) focuses on research and development being carried out at NYNEX to solve business problems. Component technologies are described; design decisions are considered, including interactivity, connectivity, and locus of control; potential perils of VR are discussed, including user dissociation; and areas of promise are…

Describes a study which analyzed think-aloud protocols of four expert and four novice instructional designers working on a design problem in physics instruction. Differences between novices and experts in problem interpretation, problem analysis, problem representation, solution generation, the solution, internal resources, external resources, and…

Clapping music for two performers provides the basis for a series of mathematical problems in combinatorics and group theory. A discussion provides insight about how to avoid overlooking global extrema in constrained max-min problems when solving systems of algebraic equations. (JJK)

Described are how students (n=2,000) reduce the complexity of multivariable problems. Tendencies toward "functional reduction" in common reasoning are shown to range from a simple reduction in the number of variables considered, to a more elaborate procedure where all variables are taken into account, but in a simplified way involving…

Mathematics portfolios need not be limited to problem-solving efforts. When California algebra teacher asked students what portfolio contents would show their effort and learning, they suggested daily notes, personal budget and lottery projects, scale drawing, their best and worst tests, weekly problems, daily class notes, and homework. Students…
