GRADES OR AGES: Grade 2. SUBJECT MATTER: Reading, language arts, spelling, writing, literature, arithmetic, social studies, science, health, art, physical education. ORGANIZATION AND PHYSICAL APPEARANCE: In addition to a chapter on each of the subjects covered, the guide includes a suggested weekly time allotment and daily program, and an appendix…

The investigation examined the "Wide Range Achievement Test" (WRAT) and its subtests (spelling, reading, and arithmetic), as well as possible differences attributable to the factors of sex, with the "Chicago Non-Verbal" (CNV) as a criterion variable. The 1970 study encompassed 72 Indian students (with a mean chronological age…

DISTAR programs were used in learning assistance classes at five Vancouver schools during 1971-72. Those pupils who were taught with the DISTAR Arithmetic program made sizable gains in scores on the Arithmetic subtest of the Metropolitan Achievement Test, but the difference between the gains made by experimental and control groups in arithmetic…

MIDDLE-CLASS, FIRST-GRADE STUDENTS (100) WERE TESTED INDIVIDUALLY ON 4 ITEMS OF CONCEPT OF ADDITION AND CONSERVATION OF NUMBER. THE TEST ITEMS WERE IDENTICAL EXCEPT FOR THE NUMBER OF OBJECTS INVOLVED. FOR EACH ITEM, TWO PILES OF CANDY WERE PLACED BEFORE EACH CHILD AND THEN MOVED TOGETHER. THE STUDY SHOWED NO MAJOR DIFFERENCE IN THE MEAN…

Increasing availability of hand-held calculators in the student's world forces educators to take a hard look to see what course the schools should take in mathematics education. Planned research and development will be necessary in the next decade to explore a variety of options that schools may use. (Author/JP)

Data from the Japanese standardization of the Wechsler Preschool and Primary Scale for Intelligence were used to analyze the structure of abilities of Japanese children in terms of the Burt-Vernon hierarchical model of intelligence. It was suggested that the pattern of cognitive strengths and weaknesses that emerged would help clarify a number of…

Reports on a study into first grade student's interpretations of the equals sign in different contexts. Argues that varying situations affect students' understanding of such arithmetic concepts, including the social interaction patterns in the classroom during arithmetic instruction. (TW)

Defines arithmetic, harmonic, and weighted harmonic means, and discusses their properties. Describes the application of these properties in problems involving fuel economy estimates and average rates of motion. Gives example problems and solutions. (CW)

The study examined basic counting competencies, difficulties, skill progressions, and variation among 36 moderately retarded and 64 mildly retarded students (ages 5-14). Quantitative and qualitative analyses indicated deficiencies in basic counting competencies and systematic oral- and object-counting errors. Striking individual differences in…

Presents a rationale and activities for using teacher-made laminated strips to teach fraction division concepts. (PK)

Four males, aged 11-18, who had poor achievement in mathematics, used the Lasermaths software program for practice and drill in basic arithmetic problems. After exposure to this program, which resembles a video game, subjects' performance on paper and pencil arithmetic tests was significantly improved. (GDC)

A newly introduced approach, rule space, can represent large numbers of erroneous rules of arithmetic operations quantitatively and can predict the likelihood of each erroneous rule. The new model challenges the credibility of the traditional right-or-wrong scoring procedure. (Author/PN)

This study investigated the fluency with which first-graders with strong, moderate, or weak mathematical abilities apply the decomposition-to-10 and tie strategy on almost-tie sums with bridge over 10. It also assessed children's memorized knowledge of additions up to 20. Children's strategies were analysed in terms of Lemaire and Siegler's model…

In contrast to the traditional top-down approach, a bottom-up approach is proposed by current reform in mathematics education. According to this alternative proposal, algorithmizing is the activity in which students should be involved. What can we do when we want to enact such an algorithmizing approach in a classroom and our students have already…

Previous findings have indicated that the reasoning abilities of gifted students are associated with gender differences. However, the factors affecting the emergence of gender differences, including age, remain to be studied. The main purpose of this study is to investigate whether the spatial, verbal and quantitative reasoning abilities of gifted…
