Shows how teachers can move beyond holistic teaching by engaging students in critical learning. Appropriate activities include introducing a research topic, development of the research question, additional research, data analysis and report writing, presentation of the report to the class and making recommendations for possible action, and…

Studies the effect of vocabulary glossing on reading comprehension in second-language learning. Findings reveal that there was a significant effect for glossing but no significant interactions between the treatment and any of the other variables, i.e., psychological type, tolerance of ambiguity, proficiency, frequency of gloss use, perceived value…

This paper describes a data-based case study of a linked array of community-based treatment services for troublesome, dual-diagnosed children and adolescents. Factors in the program's successes are described, followed by long-term data supporting treatment effectiveness. Results support applied research at this level and present a simple…

Describes a science activity appropriate for middle and high school students investigating the temperature, pH, and conductivity of a man-made lake. Uses an inquiry-based interdisciplinary approach. Collects and analyzes data to determine whether there is any significant difference among the factors considering the very little variance in lake…

A primer for schools attempting to analyze the data they collect. Describes ways schools can get a better picture of how to improve learning by gathering, intersecting, and organizing four categories of data more efficiently: (1) demographic data; (2) student-learning data; (3) perceptions data; and (4) school-processes data. (WFA)

Questions raised by contemporary research on mathematical giftedness were addressed in a longitudinal study based on a random stratified sample of 95,650 tenth graders and a subsample of 497 mathematically gifted boys and 508 mathematically gifted girls from this larger pool. Gender differences and educational outcomes are discussed. (SLD)

Described is an instructional strategy that has incorporated a form of cooperative learning. The three parts of this method are presented as a multimodal discussion cycle. The use of this method with students having special learning needs in mathematics has been found to be particularly effective. (KR)

Described is an experiment in which the student can ascertain the meaning of a negative result from a qualitative test by performing a more sensitive quantitative test on the same sample. Methodology for testing urinary glucose with a spectrophotometer at 630 nm and with commercial assaying glucose strips is presented. (MVL)

Describes issues which are common to all research methodologies and some that were unique to the assessment techniques used in the Child Development Project (CDP) in San Ramon, California. Looks at the limited amount of time given assessments and the "fluid" nature of measurements. Notes that CDP issues involved observations,…

Reasons for evaluating intergenerational programs are presented, and unique features and basic components of these evaluations are described. Strategies and methodologies used in the program evaluation process are systematically outlined. Careful and serious evaluation can provide insights into problem areas, successful program elements,…

This set of activity sheets requires students to organize and display data with a box-and-whiskers graph. Students use the plot as a summary display to detect patterns and to highlight the important features of the data for purposes of comparison. (PK)

Studied the effect of content knowledge on learners' participation in interactions between nonnative speakers. Measures of participation included amount of talk, conversational fillers, back channels, topic moves, clarification questions, and confirmation and comprehension checks. Findings support the relationship between knowledge and…

Reviews factors influencing reversals of expectations for language-learning outcomes. This article touches on psychological and neurological data regarding individual differences in language-learning mechanisms and focuses on cross-linguistic psycholinguistic analysis that indicates that different target languages offer a wide variety of learning…

Describes two QuickBASIC programs that provide students direct experience with interpreting correlation scatter-plots. Maintains that the programs can be used in classroom exercises to highlight factors that influence the size of a Pearson correlation coefficient. (CFR)

Describes a QuickBASIC program for demonstrating the differences between main effects and interactions in factorial designs. The program can be used in conjunction with a traditional lecture to improve student understanding and develop skills in recognizing main effects and interactions from graphic displays. (CFR)
