By means of a case study of Nigeria, this paper examines the issue of national unity and identity in the face of tribally based regionalism, diversity, and suspicion. Maps and tables accompany the article. (Author/AV)

Curriculum for teaching multiplication and division story problems was delivered via either computer-assisted tutorial or teacher-assisted instruction to two groups of mildly handicapped middle school students (n=19). No significant differences were found, indicating that computer-assisted instruction is effective when sound instructional design…

Describes integrated teaching systems (ITS), formerly called integrated learning systems, and discusses guidelines to be considered when purchasing an ITS. Topics discussed include instructional theories, appropriate grade levels and curriculum areas, management and reporting systems, and cost considerations. A list of vendors offering ITS and…

A 1988 Johns Hopkins University survey gathered data on organizational variations among schools containing grade seven to study how grade span affects school programs, teaching practices, and student progress. This article reports selected results on the relation of grade span to school size, grade level enrollment, school goals, report card…

Describes environments for concretely enacting multiplication and division. Discusses difficulties occurring when students use one of the concrete environments to model situations involving modified environments. (YP)

Studied were the misconceptions that preservice elementary teachers have about multiplication and division. Results indicated that they are influenced by the same primitive models as students; the most common errors made by both groups are quite similar. (MNS)

Use of a microcomputer spreadsheet program to help students understand long division is described. An example of a problem with powers of 10 used with seventh graders is presented, with note of another lesson on decimals for grade 6. (MNS)

Surveys of 663 students in grades 3-6 in 6 small rural Texas school districts found that student attitudes toward mathematics became more negative as they progressed through elementary school. Girls had more positive attitudes than boys, but gender differences decreased at higher grade levels. (SV)

Presents a problem solving strategy developed by a second grade student that goes beyond modeling an intuitive or informal interpretation of an operation to solve division problems. Concludes that good teaching should build on pupil's existing preinstruction knowledge and recognize a pupil's attempts at creative solutions. (MDH)

The relationships among grade, substance assessed, and type of measurement and statistical analysis used in the detection of external validity threats resulting from subject attrition in a modal follow-up study were examined in 6 successive 2-year panels of adolescents, including 4,819 overall stayers and 1,897 dropouts. (SLD)

Presented is an activity which examines an arithmetic concept from a geometric point of view. Objectives, prerequisite learning, and procedures are discussed. Four worksheets are provided with answers. (CW)

According to a 2-year study of over 1,500 middle-level classrooms in California and Missouri, most writing programs are not woven into the fabric of middle-school programs, practices, or policies. Programs are couched within the English/language arts curriculum. Four factors affect programs--teacher characteristics, commitment to middle-school…

Investigated the effects of four writing experiences, grade, and reading level on elementary students' narrative writing. For 14 days, students wrote in response to 4 stimuli. Poststudy writing samples indicated students wrote in response to a common but different writing prompt. There were main effects for grade and reading level. (SM)

Presents educational games to promote mathematical reasoning and problem solving in the primary grades. Children take charge of their learning and create exciting challenges for one another. (ASK)

Examines in-season and off-season use of alcohol by high school athletes. Changes in the odds of use were determined for gender, grade level, race, school classification, and geographic region. Results show that the odds of high school athletes using alcohol were less, both in- and off-season, in 1996 than in 1988. (MKA)
