Presents two class activities for use with hypothesis testing in which students collect data to test for a difference in the mean number of chocolate chips per cookie between two brands. (Author/ASK)

Describes some student explorations of angle rotations and of reasonable and unreasonable conjectures using the Geometer's Sketchpad. (MKR)

Discusses a lesson designed to demonstrate hypothesis testing to introductory college psychology students. Explains that a psychology instructor demonstrated apparent psychic abilities to students. Reports that students attempted to explain the instructor's demonstrations through hypothesis testing and revision. Provides instructions on performing…

A project involving third-year college geography students in determining the most accurate method of predicting mean flow velocity in a stream, using three different methods of estimating Manning's roughness coefficient, is described and evaluated. (Author/RM)

Demonstrated is the use of BASIC computer programs to simulate a binomial experiment and test a simple statistical hypothesis. The theoretical results are reached with the third programing attempt. All results, as well as computer programs, are included. (JJK)

This paper describes a research and development project in teaching designed to examine whether and how it might be possible to bring the meaning of knowing mathematics in school closer to what it means to know mathematics within the descipline by deliberately altering the roles and responsibilities of teacher and students in classroom discourse.…

Presents 17 research paradigms students might employ for doctoral dissertations on instructional design, makes suggestions for students evaluating the literature and developing a conceptual framework for research, and summarizes dissertations developed by University of Florida doctoral students, classifying them into three research paradigms which…

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)

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…

Clarifies the idea of prediction in science teaching by distinguishing between the two extremes of guessing and making logical deductions. Discusses the use of predictions in testing teachers' and students' explanations. (MDH)

Presents a laboratory activity for use during the first or second week of school that engages students in the basic principles of the scientific method. (PR)

Science process skills such as observing, classifying, inferring, interpreting, predicting, and hypothesizing can all be classified as a sub category of thinking skills. This book is part of the series "Strategies for Learning" that focuses on the step-by-step development and application of thinking skills as a vehicle for learning science. The…

This book provides information on what works in education, how teachers can find what works, how educational research can find its way into classrooms, and how teachers can apply it to help individual students. Data come from a meta-analysis of research studies on instructional strategies that could be used by K-12 teachers. Nine research-based…

Describes the model for decision making used in inferential statistics and real-world applications that parallel the statistical model. Discusses two activities that ask students to write about a personal decision-making experience and create a mock trial in which the class makes the decision of guilt or innocence. (MDH)
