Discusses the variety of performance measures available for information retrieval systems, search engines, and network filtering agents. Considers how measures of performance at a point in a search can be formally compared, develops criteria related to document orderings, and discusses equivalent ordering and precision and recall.

A study used the Assessment of Basic Learning Abilities to assess the abilities of three adults with mental retardation in order to reduce aberrant behavior. There was a higher frequency of aberrant responses during training sessions with training tasks above or below a participant's assessment level on the test. (Contains references.) (CR)

Examined preschoolers' ability to map novel adjectives to object properties in two experiments. Found that 4-year-olds could extend novel adjectives from target to matching test object whether objects were drawn from same, or different, basic level categories. If 3-year-olds' first extended a novel adjective to objects in the same basic level…

Three experiments investigated use of visual input and body movement input arising from movement through the world on spatial orientation. Experiments involved infants searching for a toy hidden in one of two containers. Findings indicated that search was best after infant movement in a lit environment prior to searching; all other conditions led…

Compared performance of children with autism, with learning disabilities, and normally developing 4-year-olds on reasoning problems with and without instruction to use imagery. Found that instruction to use imagery led to persistent logical performance. Children with autism displayed a distinctive response pattern, performing around chance levels,…

Explores mathematics results for seventh and eighth graders in South Africa on the Third International Mathematics and Science Study (TIMSS) test. Discusses reasons for South African students' relatively low performance by analyzing student background factors. Suggests research needs to study mathematics performance factors in more detail. (SLD)

Investigated effects of two instructional interventions on 5- to 9-year-olds who could perform a balance beam task but either could not explain the principle or had naive theories. Found that more students who had observed the experimenter model and were then encouraged to explain what they saw improved performance over the pretest than students…

Compared results from computerized vocabulary tests under conditions in which item review was permitted or not permitted. Results from 177 college students reveal that performance gains after review were greater for examinees of high ability, and that review was desired more by examinees with higher test anxiety. The major drawback to review was…

Faced with the absence of a conceptual framework and the terminology for establishing evaluation criteria in the substance abuse prevention services field, this special issue is devoted to exploring the topics of accountability and performance measures. It discusses the requisite components (i.e., theory, methodology, convention on terms, data)…

Seventy-eight special-education students (ages 8-13) and 403 typical students took a large-scale statewide test using standard test administration procedures and two major accommodations addressing response conditions and test administration. No differences were found in the response conditions; however, students with disabilities who were read a…

Whether reader-generated illustrations are as effective as experimenter-provided illustrations in giving students the ability to understand scientific explanations was studied with 92 college freshmen. Students given illustrations and those who generated their own performed better on a test than students without illustrations, with no significant…

A scale to assess the goal of avoiding the demonstration of lack of ability (performance-avoid) was included with scales assessing approach goals for 703 sixth graders. Performance-avoid scales negatively predicted academic efficacy and positively predicted avoiding seeking help and test anxiety. Implications for goal theory are discussed. (SLD)

Two studies involving 160 kindergarten students investigated children's involvement in shared thinking with varying adult support and children's later performance on a categorization task. Results indicate that children benefit from working with an adult who provides some leadership in learning categorization skills. (SLD)

Studied the impact of practice tests on students' calibration and examination performance for multiple-choice and essay examinations. Results for 59 graduate students show that practice tests were associated with significantly lower scores on the midterm multiple-choice items and less accurate predictions and postdictions on these items. Discusses…

A four-year study explored face-to-face English competence of five students (ages 7-12) with deafness participating in a study of teachers' use of English-based signing. Grammatical forms similar in English and American Sign Language were initially more readily produced when tested for in English and students showed consistently higher attainment…
