Assessment and evaluation are at the heart of all functioning systems, as progress can be determined with the information collected by these assessments. The problem addressed in this study is the lack of actionable data to evaluate whether assessments aligned with Montessori benchmarks support the achievement of student outcomes. To address the…

Randomized experiments are often seen as the "gold standard" for causal research. Despite the fact that experiments use random assignment to treatment conditions, units are seldom selected into the experiment using probability sampling. Very little research on experimental design has focused on how to make generalizations to well-defined…

The study reviewed in this paper examined the effects of "mastery learning" and "student team learning" on the math achievement of high school students. The analysis included 588 ninth-grade students in 16 urban Philadelphia high schools. The study assessed the effectiveness of the different conditions after one year by…

Independent schools are, for the most part, exempt from mandatory participation in standardized tests designed for state and federal comparisons, nor are they required to take part in comparative international assessments. The anxiety in the broader culture, however, is driving a growing interest among independent school parents (and prospective…

This study examined the effect of kindergarten entry age on the scores of the eighth grade Comprehensive Test of Basic Skills (CTBS) math and reading scores, while controlling for the demographic variables of gender and socioeconomic status. The subjects included 1,197 students who participated in the randomized, long-term STAR (Student-Teacher…

A panel of expert referees from the Philadelphia school district categorized items from secondary-level standardized mathematics tests according to National Assessment of Educational Progress (NAEP) subobjectives for mathematics. The following tests were covered by the study: (1) California Achievement Tests (Levels 19 and 20); (2) Comprehensive…

This 5-year longitudinal randomized study focused on the effects of a dropout prevention program implemented at two urban high schools. The program incorporated the characteristics of personalization found in previous research to have some positive effects, and typical of the type of programs implemented in many high schools nationwide. The…

In December of 2004, media outlets across the country were abuzz with news of the just-released results of the latest Trends in International Mathematics and Science Study (TIMSS) tests. Once again despite highly publicized efforts to reform American math education over the past two decades, the United States did little better than average. Taken…

Of the many factors that have been proposed as a rationale for poor mathematics conceptualization by American Indians, cultural factors remain the most popular when explanations are submitted. Additionally, the accepted fault for poor achievement is focused upon mathematics anxiety. A study of American Indian school mathematics achievement and…

Experiments that assign intact groups to treatment conditions are increasingly common in social research. In educational research, the groups assigned are often schools. The design of group-randomized experiments requires knowledge of the intraclass correlation structure to compute statistical power and sample sizes required to achieve adequate…

The effects of the use of computer-enhanced instruction with remedial students were assessed, using 4,293 ninth through twelfth graders--3,308 Black, 957 White, and 28 Other--involved in the Governor's Remediation Initiative (GRI) in Georgia. Data sources included the Comprehensive Tests of Basic Skills (CTBS), a data collection form developed for…

The purpose of this practicum was to develop and implement a remedial mathematics program to improve the basic mathematics skills of seventh-grade students at Nathan B. Young Junior High School who fail to master the required minimal objectives on the seventh-grade "Criterion Referenced Test" (CRT). Target students were screened for…

A test of whether metacognition is a separate factor from cognition was conducted by measuring the effects of metacognitive factors in problem solving, while attempting to hold relevant cognitive factors constant. Learning disabled subjects were less skilled in metacognition with respect to knowledge about cognition and regulation of cognition.…

To help teachers in comparing the content of their instruction with the content of standardized tests, a taxonomy of elementary school mathematics was developed. The taxonomy consisted of matrix with three dimensions; (1) mode of presentation (how questions are asked); (2) nature of material (type of numbers or mathematical terms); and (3)…

Two questions motivated this study: (a) Does test familiarity influence teachers' judgments of their students' test performance? and (b) Does the disability status of students influence their teachers' judgments? Teachers (n=19) judged item performances for one student with disabilities and one student without disabilities (n pairs=19) from their…
