The nation is showing an unprecedented focus on increasing the rigor in education and preparing students for college. The college readiness trend is driving changes in the ways in which the nation uses student test data. Educational data are no longer limited to static data snapshots showing the status of a student performance at one point in…

Science education in Malaysia nurtures a science and technology culture by focusing on the development of individuals who are competitive, dynamic, robust, resilient and able to master scientific knowledge and technological competency. To this end, the science curriculum in Malaysia gives conscious emphasis to the acquisition of scientific skills…

The relationship between the intentional teaching of reading strategies and the increase in reading comprehension was studied. The Northwest Evaluation Association (NWEA) reading pretest and posttest scores of 57 subjects were analyzed to see if there was a significant increase in performance after the reading strategies were taught. The study…

Proponents of class size reductions (CSRs) draw heavily on the results from Project Student/Teacher Achievement Ratio to support their initiatives. Adding to the political appeal of these initiative are reports that minority and economically disadvantaged students received the largest benefits from smaller classes. We extend this research in two…

The purpose of this observational study was to identify the frequency of reading comprehension instruction in elementary classrooms. Additional objectives were to determine which reading comprehension instructional strategies were most employed by teachers in elementary classrooms. In 3,000 minutes of direct classroom observation in 20 first-…

Thirteen children and young adults with Down syndrome (DS) completed tests of language and reading and their performance was compared to that of three control groups. Reading comprehension was confirmed to be a specific deficit in DS and found to be strongly correlated with underlying language skills. Although reading comprehension was more…

This article describes the core features of outcome research and then explores issues confronting researchers who engage in outcome studies. Using an intervention research perspective, descriptive and explanatory methods are distinguished. Emphasis is placed on the counterfactual causal perspective, designing programs that fit culture and context,…

Rating scale design and development for testing speaking is generally conducted using one of two approaches: the measurement-driven approach or the performance data-driven approach. The measurement-driven approach prioritizes the ordering of descriptors onto a single scale. Meaning is derived from the scaling methodology and the agreement of…

Recent interest in studying social aspects of leadership has brought attention to the relationship between leadership and social capital. There is also growing interest among stakeholders (researchers, practitioners, funders, and program participants) to improve evaluation methods for leadership development programs (LDPs). The purpose of the…

The main goal of the study was to map the difficulties and cognitive processes among adolescents (aged 13-21, N = 30) and adults (aged 25-66, N = 30) with mild and moderate intellectual disability (ID) when solving analogical problems. The participants were administered the "Conceptual and Perceptual Analogical Modifiability" test. A…

Background: Professional standards for validity of achievement tests have long reflected a consensus that validity is the degree to which evidence and theory support interpretations of test scores entailed by the intended uses of tests. Yet there are convincing lines of evidence that the standards are not adequately followed in practice, that…

The purpose of this article is to report the results of a study that examined young readers' metacognitive processes and strategies while reading. An interview procedure was conducted while 109 children (high, average, and low readers) in kindergarten (three classrooms) and first grade (four classrooms) read familiar and unfamiliar text.…

Geoscience instructors and textbooks rely on analogy for teaching students a wide range of content, from the most basic concepts to highly complicated systems. The goal of this paper is to connect educational and cognitive science research on analogical thinking with issues of geoscience instruction. Analogies convey that the same basic…

Rate of change is an important concept for students to study, and little is known about the ways in which secondary students make sense of rate of change. In this qualitative study I examined how four high school students who have not taken calculus reasoned about changing quantities when interacting with mathematical tasks involving multiple…
