This paper reports on a 3-year, NSF-funded research and development project called ACED: Adaptive Content with Evidence-based Diagnosis. The purpose of the project was to design, develop, and evaluate an assessment for learning (AfL) system for diverse students, using Algebra I content related to geometric sequences (i.e., successive numbers…

Background: Tobacco use, poor eating habits, and physical inactivity are the modifiable risk behaviors most associated with the leading causes of morbidity and mortality in the United States. Because these risk behaviors are established during adolescence, the nation's schools are uniquely positioned to develop health literacy in students.…

This study sought to determine the effect of simulation-games environment on students' achievement in attitudes to mathematics in secondary school. Data was collected from a sample of 147 students in senior secondary school in Osun-State, Nigeria. t-test and analysis of variance was used to analyze the data collected for the study. The finding…

Learning in educational settings most often emphasizes declarative and procedural knowledge. Studies of expertise, however, point to other, equally important components of learning, especially improvements produced by experience in the extraction of information: "Perceptual learning." Here we describe research that combines principles of…

The objective of this study was to determine the effectiveness of a district-wide professional development effort based on a modified Ramp-Up Program, designed to help high school teachers improve the reading skills of their students. Ramp-Up is a two-year course that seeks to accelerate the learning progress of entering high school students who…

Expanded captions are designed to enhance the educational value by linking unfamiliar words to one of three types of information: vocabulary definitions, labeled illustrations, or concept maps. This study investigated the effects of expanded captions versus standard captions on the comprehension of educational video materials on DVD by secondary…

Systemic functional linguistics (SFL) was the foundation for this study that explored the effect of science text and image integration on grade 9 students' reading comprehension. Two texts in Chinese on the moon phase with different print and image integration were compared--a traditional textbook (TT) used in Taiwanese junior high schools and a…

This study investigated the effects of using the cooperative concept mapping (CCM) teaching approach on secondary school students' motivation in biology. A non equivalent control group design under the quasi-experimental research was used in which a random sample of four co-educational secondary schools was used. The four schools were randomly…

We report the results of a controlled evaluation of an interactive on-line tutoring system for high school math achievement test problem solving. High school students (N = 202) completed a math pre-test and were then assigned by teachers to receive interactive on-line multimedia tutoring or their regular classroom instruction. The on-line tutored…

It has been assumed that combining living in a native speech community with formal classroom instruction creates an ideal learning environment for foreign language learners. This study examines the extent to which formal instruction affects the oral discourse of advanced learners in target-language speaking environments. From a discourse…

This article reports on the results of a research study that investigated the effectiveness of using an algorithmic approach to error correction to help Hong Kong English-as-a-second-language (ESL) learners overcome persistent lexico-grammatical problems. Ten error types were selected for the experiment, and one set of remedial instructional…

A lack of reading quantity in EFL (English as a Foreign Language) classrooms has remained one of the most serious problems faced by teachers of English in Japan. Although the extensive reading (ER) approach is regarded as having significant potential in addressing this problem, it is not used in many EFL classrooms. This study investigates the…

The purpose of this research was to evaluate a parent intervention programme, open to parents of children in Year 7, aimed at assisting parents to help their children achieve their full potential. The benefit for parents themselves was also examined. Unlike many existing evaluations of parent intervention programmes, it drew upon statistically…

Over the course of history, scientists have constructed models and equations that provide insight into the motions of the heavens. However, research indicates many people hold alternative conceptions that, to them, explain the same observable phenomenon. Science educators have found that students learning about lunar phases may hold misconceptions…

Career development objectives, as codified in the American School Counselor Association's National Standards, can be overshadowed by the growing emphasis on academic standards, testing, and accountability so thematic of national educational and public policy initiatives.
