A basic question of instructional interventions is how effective it is in promoting student learning. This paper presents a study to determine the relative efficacy of different instructional strategies by applying an educational data mining technique, learning decomposition. We use logistic regression to determine how much learning is caused by…

Using publically available data, states coded as "blue" based upon results from the 2004 presidential election were significantly higher in education funding than were states coded as "red." Students in blue states scored significantly higher on outcome measures of math and reading in grades four and eight in 2004 and 2007 than did students in red…

This study was designed to examine the impact NCLB defined teacher-quality variables (1) major/minor in mathematics, (2) highest academic degree, (3) type of teaching certificate, (4) years taught mathematics (NCLB, 2001) on the mathematics average scale scores of eighth-grade students. The study used a secondary analysis of the 2007 National…

According to the national results of the English diagnostic test (2004) applied to Chilean 8th and 12th graders, the current English teaching methodology used in this country is not efficient nor effective. Consequently, a different methodology is urgently needed, particularly in a context where students primarily come from rural areas and will be…

This paper outlines current theories of teacher practice that seek to promote equity from critical perspectives, and contributes to the empirical research on critical mathematics equity practice. Part of a larger study of equity and mathematics teacher practice in an urban public school, this paper reports specifically on the involvement and…

Aptitude and achievement subtest scores (Ohio Survey Test) of 181 male eighth grade students were factor analyzed. Subjects were classified into four groups on the basis of ethnicity (black and white) and socioeconomic status (SES) (low and middle). Performance on nine tests developed by Guilford, as well as students' grade point averages in…

Educational assessment is a process of collecting evidence and interpreting it to provide instructors with information regarding students' learning. However, the current design and scoring of most standardized educational tests are insufficient to serve this purpose. The limitation exists primarily due to the lack of cognitive information…

In 1998 and again in 2002, samples of eighth grade students in California were tested in reading as part of the state-level component of the National Assessment of Educational Progress (NAEP). In each of these years, all eighth graders in the state were also required to participate in the state's accountability testing, which included the reading…

It is postulated that mean square fit statistics do not adequately evaluate the quality of test items adequately. The fit statistics arise from the desire to have statistical (computerized) procedures to assess item quality transcending the group on which they are computed. It appears that none of the current formulations meet these criteria. The…

This research report describes the findings of a study on teachers' ways of interpreting student responses to tasks involving equivalent expressions. The teachers in this study were engaged in model-eliciting activities designed to promote the development of their knowledge and reveal their models (or interpretations) of their students' algebraic…

In this study we explored the effectiveness of individualizing instruction using a system that diagnosed students' knowledge gaps in pre-algebra and provided individualized instruction and practice. One hundred middle school students participated, and received either no instruction or individualized computer-based instruction. Diagnosis of…

The purpose of this study was to investigate the effects of multiple intelligences (MI) teaching approach on 8th Grade students' achievement in and attitudes toward science. This study used a pretest-posttest control group experimental design. While the experimental group (n=30) was taught a unit on acids and bases using MI teaching approach, the…

The proportion of variance in student achievement that is explained by student SES-"poverty's power rating," as some dub it--tends to be lower among smaller schools than among larger schools. Small schools, many claim, are able to somehow disrupt the seemingly axiomatic association between SES and student achievement. Using eighth-grade…

Multi-line-multi-operation calculators such as the TI-80 provide eighth-grade prealgebra and algebra students with significantly better computational tools for basic order-of-operation problems involving integers and signed rational numbers than do calculators offering only last-entry-or-result displays. Effects are more apparent for weaker…

Over the past 30 years the International Association for the Evaluation of Educational Achievement (IEA) has conducted three international studies of mathematics at the 13-year-old level. In the three studies, in addition to mathematics achievement tests, students were required to respond to an attitude questionnaire concerning their attitudes…
