The equivalence between a statement and its contrapositive is so obvious for an expert that, usually, he does not need any explanation. In this paper, we shall examine the argumentations which students produce in order to justify a statement that, in their opinion, is equivalent to a given statement. We shall observe that the most common…

The study was carried out within the framework of a project that provided afterschool mathematics tutorial sessions to 10th-12th grade students by engineers in an informal setting. The participating students were selected from advanced level mathematics classes according to their need for additional support. The main goal of the study was to…

This paper explores the effect of using concept maps as study tools on achievement in chemistry. Tenth grade students engaged in building concept maps as homework to investigate the correlation between their mastery of concept mapping skills and their achievement in chemistry, and gender differences in using concept mapping as a homework tool.…

Data from the National Educational Longitudinal Study of 1988 are used to link students with particular teachers and classes to estimate the impact of observable and unobservable schooling characteristics on student outcomes. A variety of models show some schooling resources, particularly teacher qualifications, to be significant in influencing…

In 1980, the Michigan Educational Assessment Program (MEAP) revised the instruments used to assess basic skills attainment in mathematics and reading of all students in grades 4, 7, and 10. The research summarized in this paper examined the factor structures of the 1979 and 1980 versions of the Grade 10 MEAP mathematics test. These two versions…

This paper examines some ethical problems that arose in a study of secondary curriculum, where educational criticism was used as a primary research strategy. A study on the subject of curriculum consonance was conducted in three tenth-grade history classrooms. In its original design, the study was primarily concerned with the correspondence…

A study was conducted to investigate the compensatory effects of graphic organizers on text organization. Subjects were 114 tenth grade students who read two versions of an expository passage containing identical information but differing in top level structure. The version organized to show opposing views (comparison/contrast) was considered…

The extent of congruence of the underlying factor structures of the learning environment and cognitive variables for mathematics and English courses in grade 10 are presented. The Learning Environment Inventory (LEI), the Otis-Lennon Mental Ability Test, and the Sequential Tests of Educational Progress were administered to 317 students. The…

These papers presented at a symposium describe how tenth grade students would be taught the slope of a line in geometry using three different approaches to teaching theory: behaviorism, Piagetian cognitive development, and information processing. Analyses of each approach focus on manner of learner cooperation and differing teacher role. (MBR)

This study examined the influence of female students' (N=90) self-monitoring and attribution on achievement when throwing darts. It was hypothesized: (1) that students who set strategic process goals and used self-evaluative recording would attribute outcomes to strategic causes; and (2) that students who set outcome goals and did not use…

The purpose of this study was to examine Turkish high school students' perceptions of learning environment in biology classrooms and to investigate relationships between learning environment and students' attitudes toward biology. Secondly, the study aimed to investigate the differences in students' perceptions of learning environments in biology…

The Arabic version of I. G. Sarason's (1984) Reactions to Tests scale was used to examine the impact of using item parcels on ad hoc goodness of fit indices in confirmatory factor analysis. Item parcels with different numbers of items and different numbers of parcels per factor were used. Analyses were conducted on a sample of 420 tenth graders…

The relationship between high school sophomores' (N=214) self concepts in science and their science achievement, mental ability, and sex were investigated. The Self Concept in Science Scale was used as a measure of students' self concepts. Science achievement was measured by the students' tenth-grade final examination in biology. The measure of…

This study has three purposes: (1) to determine whether the graphic organizer (a schematic representation of text structure using key vocabulary terms) could be used to compensate for the effects of a passage organized with a description top-level structure; (2) to explore the effectiveness of providing students differing in reading ability with…

This paper discusses variables influencing written composition quality and how they can best be controlled to improve the reliability of assessment of writing ability. The study aimed to concentrate on the effects of different imposed time limits on student performance in written composition at grade 10 level using methods of generalizability…
