Within the Caribbean context, the island of Montserrat included, ability grouping has been employed as the major organizational strategy to address academic deficiencies among high school students. Although no sound philosophical basis for this type of class/group organization has been enunciated, recent research has shown that students with poor…

Two techniques for detecting differential item functioning (DIF) of test items are compared: (1) item response theory (IRT), using the three-parameter model; and (2) Mantel-Haenszel chi square techniques (MHCS). The steps necessary for identifying differentially functioning items are identified for both approaches. Using data from the 1988…

A study was conducted to determine whether the use of word processing improves both the amount and the quality of revision done by high school students. Subjects were 24 ninth grade students enrolled in a special class for interested writers, and therefore probably better than average ninth grade writers. Twelve students were assigned to an…

The handling of mistakes in the mathematics classroom is an area in which only little research is done so far. In mathematics education there are, in fact, several investigations about students' mistakes from a diagnostic perspective, but hardly any studies on the question how teachers react in concrete mathematics lessons. In this article…

In this paper we focus on the role of signs in students' perceptive processes underpinning the generalization of numeric-geometric patterns. Based on a videotaped Grade 9 classroom group activity undertaken by three students and framed by a cultural-semiotic theoretical perspective, we carry out a microgenetic analysis of an elementary form of…

In the framework of a long term teaching experiment we present an Educational approach based on the use of a dynamic geometry software and a symbolic manipulator. Here we present the general ideas of the followed approach focusing on how meanings can originate from phenomenological experience and evolve under the guidance of the teacher. In…

This study examined the conceptions of teacher evaluation criteria of 9th- and 12th-grade teachers and administrators. Four representative members of each group (n=12) were interviewed and asked to identify and define indicators of instructional practice based on the context of their allocated roles and experiences. It was hypothesized that…

This study examines the effects of early experiences and behaviors on course failure, grade point average, and educational aspirations, analyzing survey data gathered from 20 high schools participating in a whole-school reform initiative aimed at helping troubled high schools. All of the schools served mainly poor and minority students. Students…

The influence of gender, sex-role orientation, and self-esteem on coping strategies was looked at for adolescents. The COPE scale was given to 8th and 9th grade students (N=306) in two suburban mid-western schools to determine the coping strategies they recently used to deal with stressful peer-related situations. Measures of demographic…

This paper examines the extent to which home background and school climate affects ninth grade students' social and political understanding and participation. Using the data from the student questionnaires (n=3106) of the 1999 Civic Education survey, a study was conducted in Cyprus to examine ninth graders' participation in social actions. The…

This paper synthesizes research on the value of writing in learning science at all grade levels. Breakthroughs and barriers to the effective use of writing to learn science are discussed. Differences between elementary and secondary teachers are considered with regard to background in language arts, understanding of the writing process, and the…

Path analysis was used to test the influence of writing self-efficacy, self-concept, apprehension, and aptitude on the essay-writing performance of 181 ninth-grade students in a public high school in the southwestern United States. A model that also included gender accounted for 53% of the variance in performance. As hypothesized, both aptitude…

This study explores students' conceptual thinking by examining the extent and complexity of their concept identification and organization in geography. The study investigated students' conceptual thinking through identification of salient geography concepts and construction of individual concept maps at three academic achievement and grade levels.…

This study examined the efficacy of Judith Langer's PreReading Plan (PReP) with Hispanic and other high school students. Specifically, the study investigated (1) the effect the PReP has on learning when used with predominantly Anglo and Hispanic high school students in conjunction with a social studies textbook reading assignment; (2) whether…

Results of a minimum competency test administered to ninth-grade students were evaluated to compare the performance of 723 students (345 males, 347 females, and 31 unidentified students) on content-specific and process skill questions. Subjects represented a random sample of students taking the Regents Competency Test in Science--a 70-item…
