Discussion of computer simulations used for exploratory learning focuses on the design of a hypothesis scratchpad that students can use for hypothesis generation and testing. An experiment with college chemistry students that compared three versions of the scratchpad is described, and the effect of the scratchpads on learning environments is…

Describes a study conducted at Ohio State University that used data obtained from the interlibrary loan process to determine why some users failed to find existing entries in the online library catalog. User errors as opposed to catalog errors are examined, and implications for bibliographic instruction are suggested. (eight references) (LRW)

Discussion of adolescent rebelliousness highlights a study of high school students that explored the relationship between rebelliousness as a personality trait and the enjoyment of defiant rock music. Hypotheses tested are discussed, the use of MTV concept music videos is explained, gender differences are considered, and further research is…

An evaluation of the rules-of-thumb used to determine the minimum number of subjects required to conduct multiple regression analyses suggests that researchers who use a rule of thumb rather than power analyses trade simplicity of use for accuracy and specificity of response. Insufficient power is likely to result. (SLD)

Describes a longitudinal study of serial cancellations that was conducted by analyzing the cancellation lists between 1987 and 1990 from five midwestern member libraries of the Association of Research Libraries. Highlights include serial cancellation prices, language and place of publication, Library of Congress subject analysis, and collection…

Describes a study that used a computer survey to investigate the relationship between computer attitudes and the selected variables of age, gender, and computer knowledge among adult basic education students in Texas. Hypotheses tested are explained, comparisons are made with a national sample, and recommendations for further studies are…

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)

The article suggests a method for organizing the research on teaching thinking and provides examples of indicators of teacher performance within various domains (hypothesis testing, argument assessment, problem solving, probabilistic thinking, and flexibility). Examples of empirical evidence supporting each indicator are included. (SM)

Examines the transferability of five Japanese indirect request strategies to corresponding English request contexts. Findings indicate that the Japanese strategies were differentially transferable and the transferability of each first-language request strategy was determined by interaction between the politeness and conventionality encoded in each…

Describes a time allocation study that was designed to determine how two types of teachers spent their time regarding gender differences in a primary school computer laboratory in Costa Rica. Topics include the sociocultural context of gender roles in Costa Rica, hypothesis testing, and the domination of boys in computer labs. Contains 101…

Using a narrative procedure, this study replicated Zaitchik's (1991) result that children are more likely to acknowledge another's belief when they are told about reality than when they see reality for themselves. The article argues that these children were acknowledging alternative rather than false belief. (20 references) (Author/CK)

This chapter describes a new conceptual model for measuring competencies of higher education graduates. The proposed instrument can become a valuable tool for higher education quality management, policy evaluation, and scientific research. (Contains 1 figure.)

This paper provides an Optimality Theoretic account of how Hungarian learners of English acquire /[epsilon]/ and /[ash]/. It is hypothesized that as the learners' pronunciation becomes more nativelike, L1 transfer substitutions will diminish; non-transfer substitutions will be especially prevalent in the intermediate stages, and that all learners…

Computer-based learning (CBL) is well established and its benefits are widely reported. It has found considerable utility in recent years with the explosion in interest in the use of the Web as a knowledge medium. Many online courses, however, consist merely of a series of textual notes and pictures with little navigational information or choice.…

The author's purpose in this study was to test 4 hypotheses that proposed different paths for the influences of children's television viewing on their academic achievement. Data were drawn from the 1997 Child Development Supplement (CDS) to the Panel Study of Income Dynamics (PSID). The population for this study included 1,203 children between the…
