We describe an activity that allows students to experience the full process of a statistical investigation, from generating the research question, to collecting data and testing a hypothesis. Implementation of the activity is described both with and without use of clickers, handheld remotes that allow instant data collection.

Assigning difficulty level indicators to the knowledge units helps the learners plan their learning activities more efficiently. This paper focuses on how to use the topology of a knowledge map to compute and rank the difficulty levels of knowledge units. Firstly, the authors present the hierarchical structure and properties of the knowledge map.…

Interactive applets have the ability to enhance statistics teaching by providing multiple representations of new concepts and by facilitating experimentation. I introduce two applets that have been developed as aids in illustrating ideas relevant to hypothesis testing and describe how I have used these in my classes. (Contains 4 figures.)

Describes a residential training course sponsored by the NASA Classroom of the Future to help teachers learn to use computer-based educational tools and explore constructivist instructional approaches. Hypothesized that creating a living-and-learning environment for the training would foster rapid changes in teachers' epistemological beliefs.…

Demonstrates the use of simulation systems for studying diagnostic problem solving and presents results from two empirical studies in which undergraduates diagnosed faults that occurred in a computer-based, dynamic simulation. Discusses dual problem space search that includes generating and testing hypotheses; suggests implications for designing…

Describes the Context Information System, a prototype retrieval system designed for online searching in an educational environment. Use of the system in Israeli high schools to encourage the development of research skills is discussed, emphasizing the use of databases for hypothesis testing and comparative analysis of data.

Water quality experiments, especially the use of macroinvertebrates as indicators of water quality, offer an ideal context for connecting statistics and science. In the STAR program for secondary students and teachers, water quality experiments were also used as a context for teaching statistics. In this article, we trace one activity that uses…

Compares the impact of two different computer-mediated communication (CMC) systems, with different prescribed guidelines for use, on the per-person volume of online interchanges in two graduate classes. Hypothesies a relationship between system characteristics, guidelines for use, and the perpetuation of verbal interaction in settings where CMC is…

Describes the components of SEEN, a computer program which provides an environment that prompts the user to create, support, and test an hypothesis, and its applications in an introductory world literature and an art history course. (MBR)

The mechanisms of perceptual learning are analyzed theoretically, probed in an orientation-discrimination experiment involving a novel nonstationary context manipulation, and instantiated in a detailed computational model. Two hypotheses are examined: modification of early cortical representations versus task-specific selective reweighting.…

Describes software which was developed to help collaborating pupils test hypotheses. Discusses use of the software by 9-14 year-old pupils in Scotland, comparing their activity with that of similarly aged pupils who worked with otherwise equivalent software which lacked any prompts. (Author/AEF)

Describes a multiple case study that was used to evaluate hypotheses on the critical success factors for online course resources in a Singapore tertiary setting. Discusses educational media; human factors pertaining to instructors; technical competency of students and instructors; mindsets about learning; collaboration; and information technology…

Describes two interactive computer programs that simulate abstract relationships and require students to use inductive reasoning, form and test hypotheses, and analyze functions of systems and the reasoning processes required to understand them. Their development and use in college philosophy of science courses is outlined, and possible future…

Discusses use of microcomputers for structuring, communicating, and disseminating information under the categories of instructional use (computer-assisted instruction), emancipation (number crunching), revelatory (discovery/simulation), and conjectural (hypothesis testing). Also discusses use of PROLOG language for modeling ecosystems and testing…

This discussion of teaching science as a design activity emphasizes open-ended problem solving. Highlights include the relationship between teachers and students; hypotheses as solutions; and descriptions of four microworlds, or computer simulations, in chemistry, geography, physiology, and genetics which use graphic interfaces.
