This study examines the effect varying models have on student understanding of fractions. The study addressed the question of what students know and understand about fractional concepts through the use of discrete and continuous models. A sample of 54 students in kindergarten and 3rd grade were given an interview pretest, participated in…

A computerized adaptive testing (CAT) algorithm that has the potential to increase the homogeneity of CAT's item-exposure rates without significantly sacrificing the precision of ability estimates was proposed and assessed in the shadow-test (van der Linden & Reese, 1998) CAT context. This CAT algorithm was formed by a combination of…

This investigation measured effects of the modern mathematics on achievement in traditional arithmetic and in modern mathematics. Material on Sets, Variables, and Statistics was taught as a separate subject to an experimental group of 207 sixth-grade students. Instruction in the new mathematics content was given over a four-month period, using…

The tests yielded similar scores. A qualitative analysis, comparing the tests in the areas of content, quality, time efficiency and relevance for instruction found the California Achievement Test to be superior and more efficient for accessing secondary learning disabled students' math achievement levels.

A study was conducted at North Harris County College to determine the extent to which its Developmental Studies Program (DSP) was meeting stated goals and to assess the predictive reliability of the screening tests used to place incoming students in DSP courses. The study involved: (1) an assessment of the need for the DSP program as evidenced by…

This report summarizes test score information on a city-wide, regional, and school-by-school basis for staff and community review of pupil progress in reading and mathematics achievements, Primary Unit through grade 11. The data were obtained in the 1979-80 school year. Norm- and criterion-referenced tests were used. The intent of the report is to…

The long-term sustained impact of the Saginaw School District Chapter I Supplemental Teacher Participation (STP) program on third grade students during the 1979-80 school year was examined. A total of 256 students were classified into one of four categories: 1 year, 2 year continuous, 3 year continuous, and 2 year interrupted. Two different…

The California Achievement Test was administered to the students of the Mesa Public Schools in April, 1981, and again in April, 1982. This state-mandated test is administered to all students in grades 1 through 12. Although this report is directed toward the performance of Mesa students at the elementary level, a general overview of the…

Empirical evidence is presented regarding the use of the estimated learning potential (ELP). The data reported come from three instruments: the Wechsler Intelligence Scale for Children-Revised (WISC-R), the reading and math components of the California Achievement Tests, and the System of Multicultural Pluralistic Assessment (SOMPA) Sociocultural…

To explain the discrepancy between median scores on the 1976 administration of the California Achievement Tests (CAT) and the Sequential Tests of Educational Progress (STEP) in the Austin Independent School District (AISD), ten technical variables typical of achievement tests were considered as explanations. (1) The STEP may measure different…

Problems involved in reducing the achievement gap among ethnic groups in the Seattle (Washington) public schools were studied. An 11-member team selected 25 elementary schools and 216 classrooms for the study, which included classroom observations, teacher questionnaires, and measurement of ethnic achievement gap reduction through California…

An overview is provided of the evaluation of the Lighthouse Project, an education enhancement project that began in one urban and two suburban districts. Its methodology was the context for showing how the focus on the results of a standardized achievement test in mathematics inhibited the implementation of mathematics reform in the elementary…

To meet several pre-evaluation goals of the national Emergency School Aid Act (ESAA) Evaluation study, the following activities that were undertaken are described: selection of an achievement measure; a pretest of this measure to assess student needs in schools eligible to receive funds under the Act (schools with a minority enrollment of 50…

Rapid technological advances in the last decade have sparked educational practitioners' interest in utilizing laptops as an instructional tool to improve student learning. There is substantial evidence that using technology as an instructional tool enhances student learning and educational outcomes. Past research suggests that compared to their…
