Determined extent to which eighth-grade students' (N=35) knowledge of concepts relevant to mineral classification influenced their ability to classify minerals and which concepts were most influential. Results showed that 58.7% of variance in correct mineral classification was accounted for by students' knowledge of relevant concepts, particularly…

The relative effects of cooperative, competitive, and individualistic goal structures were compared on achievement and the acquisition of high-level cognitive reasoning strategies. Results indicate that cooperative interaction, promoted higher achievement and the discovery of superior cognitive reasoning strategies. (Author/GK)

Twenty studies of the effects of teacher questions on student achievement were reviewed. Internal validity of experiments and integrity of treatments were less adequate than population and ecological validity. Whether teachers used predominantly higher cognitive or predominantly fact questions was found to make little difference in achievement.…

Describes Iowa's use of the term "mental disability" rather than mental retardation and an IQ cutoff score of 85 for classification of mental disability.

The consequences in terms of misclassifications of students that would occur by replacing the constructed-response portion of the Advanced Placement (AP) examinations in economics with more multiple-choice items were studied. The 1991 AP examinations in micro- and macroeconomics were used. Computer simulation found that a small but statistically…

Use of the SOLO (Structure of Observed Learning Outcomes) Taxonomy for developing and assessing higher-order thinking in higher education is discussed. Research into the instrument's use to discover what students know and believe about their own learning, to assess entering knowledge in a discipline, to provide models of desired learning outcomes,…

Presents a study of technical lexical structures with the aim of assisting students of English as a Second Language in processing and deciphering the lexico-grammatical realization of technology in the field of plastics. The analysis aims to show that technical terminology is closely related to grammar, and that technical lexis and grammar should…

Outlines a teaching approach for oral English for special purposes that inputs chunks of natural language orally. These "chunks" can be segmented by the learner into fixed and variable units, while simultaneously making the learner aware of the paradigmatic, syntagmatic, and phonological aspects of the language being taught.

If parents become autonomous, self-interested consumers, erosion of common purposes and…

Three studies investigated children's responsiveness to general education reading instruction as an indicator of need for more intensive interventions and found that the response-to-instruction model tested was valid.

It stresses the need for gathering a developmental history and reviews considerations in conducting different assessments related to medical condition, psychological condition, communication, language, occupational and physical therapy,…

Discussed is whether embedding generative cognitive strategies in microcomputer courseware improves student performance on cognitive assessment measures and on insect classification tasks. The effects of transactional software on students' knowledge of insect anatomy and principles of insect classification were also investigated. (KR)

Reports the findings of a survey of Rhode Island depository libraries that examined how the state's publications are cataloged by libraries and located by users. It is concluded that a system of bibliographic access based on user needs and universally adopted by the libraries would improve access. The questionnaire used is appended. (12…
