Mental-rotation task response times from 12 studies involving 505 adults--251 males and 254 females--were used to evaluate 5 hypotheses concerning sex differences derived from an X-linked genetic model. The model assumes that task facilitation in speed of mental rotation is mediated by a recessive gene. Four hypotheses derived from the model were…

Discussion of the use of selective dissemination of information (SDI) focuses on a study that proposed a model for evaluating the relationship between SDI and the number of publications authored by basic research scientists working in a corporate research and development (R&D) environment. Hypotheses and their findings are presented. (Seven…

This study, involving 59 disabled and nondisabled adolescent readers, tested A. Kennedy's "spatial map" hypothesis wherein spatial sequencing ability is important in lexical reaccess under high-demand text situations alone. Tests of the variance contributions of a spatial sequencing covariate to eye movement dependent measures of reading, across…

Discusses a new model of concept learning called prototype theory and describes an experiment with nursing education students in which the differential effects of prototype formation on classification were explored through an instructional program on the concept of shock. Hypotheses tested are discussed and results of pretests and posttests are…

Tests hypotheses from lineage socialization and generation unit perspectives on Korean student protest participation using 360 self-administered questionnaires collected at 3 Korean universities. Results indicate that these hypotheses are not mutually exclusive but support the generation unit model. (SLD)

Describes a study of undergraduate students that examined whether a structural overview of relations between sections of hypertext leads to a deeper understanding of the material. Results supported the hypothesis that a structural overview may hinder the understanding of less knowledgeable readers. (Author/LRW)

Presents a fun, inexpensive, and pedagogically useful laboratory exercise that involves indoor studies of the dispersal properties of the winged fruits (samaras) of boxelder trees. Engages students in the process of hypothesis testing, experimental design, and data analysis as well as introducing students to important concepts related to…

This study examined the role of the Internet and its usage on the level of perceived independence among people with physical disabilities. Discusses independence, perceived control, psychological self-reliance, adaptive technology, hypotheses tested, and future directions. A copy of one of the questionnaires used is appended.

Four experimental studies were designed to test, in Norwegian, the hypothesis that children's non-adultlike interpretations of pronouns may be partly attributable to a lexical factor interacting with the A-Chain Condition. (Author/VWL)

In Alberta, 167 elementary students completed an awareness of technology survey in years 1 and 3 of a study. Even before technology education, children had ideas about testing structural strength. Development of testing knowledge was not sequential. Results may have been influenced by the various ways design technology was taught during year 2.…

Describes two simple laboratory exercises that allow students to test hypotheses concerning the requirement of cell energy for osmosis. The first exercise involves osmotically-caused changes in the length of potato tubers and requires detailed quantitative observations. The second exercise involves osmotically-caused changes in turgor of Elodea…

Reviews research that supports the National Commission on Teaching and America's Future's analysis and recommendations on elementary and secondary school reform. It describes the research and programmatic work needed to test the policy hypothesis offered by the commission's report to move the field of educational reform forward in the areas of…

Examines arguments that language comes from innate, abstract knowledge of universal grammar that signers use to create new grammatical features. (12 references) (CK)

Analyzes the speech of a German-French bilingual boy and observes two major developmental phases: (1) one characterized by object drop similar to that seen in Chinese; and (2) one characterized by the acquisition of the object clitic paradigm and a shift to an adult-like morphological licensing mechanism.
