Purpose: While educators and students alike are increasingly moving to use on-line technologies, there is still much to be learned about how these tools influence student learning. The purpose of this paper is to present a comparative investigation of the online use of one undergraduate (UG) and two postgraduate (PG) student cohorts undertaking…

This article examines whether running away from home mediates the link between child maltreatment and later delinquency and victimization in adolescence. Specifically, the authors tested the hypothesis that childhood physical and psychological abuse increase the risk of a child's running away from home by the time of adolescence. Running away from…

Dropping out of school has been associated with a student's ethnicity, socioeconomic status, challenging behaviours and low academic achievement. This paper describes research conducted with 1050 students aged 12-15, in three North Queensland urban high schools to investigate issues related to Indigenous and non-Indigenous students at risk of…

Presents an activity which encourages hypothesis testing and introduces the study of prehistorical and historical societies. Students formulate a hypothesis about an artifact; then the teacher gradually introduces more information. Students refine their hypotheses and test them against what the artifact was used for. (KC)

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)

"How can the children learn," parents ask, "when they are having so much fun? How can they learn when all they do is play?" Examines the work of educational theorists in answering such questions. (Author/RK)

Describes an attempt to plot the walking speeds of crowds as a Maxwellian velocity distribution in one dimension, analagous to an ideal gas approximation. (CP)

A method was designed to provide history students an opportunity to make interpretations and form hypotheses about historical events and eras. The teacher created representative "facts" and questions about a topic and let students use them to make their own hypotheses. A sample unit on European history, 1300-1450, is included. (KC)

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)

Describes a simulated archaeological dig for a ninth-grade Canadian social studies class. Students role-play archaeological teams in 2180 AD who find well-preserved bags of "garbage." Students classify garbage artifacts, write reports hypothesizing about the households which produced them, and match the contents of their bags to…

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)

Describes the use of the "Arcane (mysterious) Can" which is a "tin" can which is permanently sealed, both air- and water-tight, by means of a home canning device. The canning procedure permits the use of a large variety of materials which can not be utilized in the ordinary mystery box. This Can activity is valuable for…

A study was conducted in 1988 by a community college librarian who was seeking an objective guide for weeding unused library books. It was hypothesized that a book not used in a certain number of years would never be used. At the beginning of the study, no books had ever been weeded although the library had begun acquiring books in 1969. To test…
