Describes a game used in a graduate course dealing with interviewing skills. When following game rules, students are required to generate hypotheses and to engage in decision making techniques. Indicates student reaction to this exercise is positive. Notes that the activity brings about disinhibition in students while providing them with pertinent…

Describes an activity appropriate for college or high school students where they make hypotheses about prearranged patterns in a deck of playing cards. (PR)

Describes an instructional strategy to help students understand behavior variations and the factors related to that variation. Maintains that the technique helps students understand the difference between a statement of association and a hypothesis. Includes a recommended diagram to help implement the strategy. (CFR)

Describes three kinds of artifact kits (the Archaeology Dig kit, Grandmother's Trunk, and the Cultural Mystery kit) that teachers can assemble for use in their classrooms that provide links to multiple literacy events for students. Gives a list of selected sources for artifacts that will enable teachers to create artifact kits. (CMK)

This paper summarizes the results of an investigation into whether women and men have different (concrete and abstract) styles of programming, and whether the standard computing curriculum is therefore biased against women. The theory underpinning the hypothesis is critically reviewed in practical programming contexts. A concrete means of testing…

Both in Europe and the United States there is a growing interest in design research. One example is the design and validation of topic-oriented teaching-learning sequences. This research may be said to have two objectives. One is to design and test "useful products", such as teachers guides and study material for students, which may be…

Problems involved in providing practical research experience in research methods courses are discussed. The two points in the research process where time is most critical are selecting measures and data collection. This paper suggests using a data base from previous research and having students conduct simulated studies based on randomly selected…

Student team techniques, involving two conceptually distinct components--a cooperative reward structure, in which students are evaluated and rewarded based on the performance of the group as a whole, and a cooperative task structure, in which students are encouraged to peer tutor--have had positive effects compared to control methods on academic…

To gather data on the effects of different modes of instruction on physician achievement in plotting mean P, O, RS, and T receptiors in electrocardiography, researchers chose a random sample of physicians who had taken a correspondence course on electrocardiography during the previous 5 years from the University of Southern California School of…

Three questions dealing with hypothesis testing are presented. Activities that can be best worked with calculators as tools are detailed and suggestions for extensions of these problems are given. (MP)

Relates how two elementary school teachers were part of a research group that met one day a week at their schools to learn about the "hypothesis-test" process. Discusses the philosophical underpinnings of the approach and describes the four-step recursive process itself, consisting of observations, interpretations, hypothesis, and curricular…

Illustrates the "hypothesis-test" teaching approach with one kindergarten student. Notes that it was the author's stepping back to watch for multiple interpretations of her observations of Jaime's behavior that gave Jaime space to think, to use his voice to make connections, and to grow. (SR)

Combines two strands: one being an exposition of the variety of explanations which are given for the phenomenon of floating; the other being the pedagogical implications which arise from the use of alternative models in science. Attention is drawn to the ethical questions that may arise when primary science seems to conflict with accepted…

This paper reports design experiments on two Japanese elementary science lesson units in a sixth-grade classroom supported by computer support for collaborative learning (CSCL) technology as a collaborative reflection tool. We took different approaches in the experiments depending on their instructional goals. In the unit 'air and how things…

Working from the 1970s to the early 1990s, Walter Alvarez and his research team sought the cause of the mass extinction that claimed the dinosaurs 65 million years ago. The present paper discusses that research in terms of eight puzzling observations, eight episodes of hypothetico-predictive reasoning, enumerative induction, and Jung's…
