Comments on S. Pogrow's suggestion that educational programs should be judged by the degree to which schools using them achieve "surprising scores." Emphasizes the importance of the use of control groups in program evaluation. (SLD)

Among the sciences, the practice of geology is especially visual. To assess the role of spatial ability in learning geology, we designed an experiment using: (1) web-based versions of spatial visualization tests, (2) a geospatial test, and (3) multimedia instructional modules built around QuickTime Virtual Reality movies. Students in control and…

In order to determine the effects of gender and scholastic ability on vocabulary retention and reading comprehension in a foreign language, 181 men and women enrolled in a first-year Spanish course were asked to either read a passage in Spanish on a computer and create annotations for a list of words found in the passage (experimental group), or…

The purpose of the study was to determine the outcomes of a low vision service that made use of an extended period of education when assisting clients with age-related macular degeneration to use low vision devices. Extended teaching time made a significant difference to the experimental group, not only in the ability to read, but in their overall…

The effectiveness of the Ecological, Futures, and Global (EFG) curriculum was evaluated in a single elementary school. The EFG curriculum is a project-based approach to learning that is integrated into a traditional curriculum. Research comparing project-based learning such as EFG with the traditional curricula has shown potential for several…

The enhancement of critical thinking skills is necessary for students pursuing degrees in science, technology, engineering, and mathematics (STEM) disciplines. A three-year mixed methods study conducted at a Historically Black College and University in Baltimore, Maryland focused on enhancing critical thinking skills for African American students.…

The purpose of this study was to determine the effects of participation in Read 180, a teacher-mediated, computer-mediated reading instruction program, on the reading proficiency of 4th and 5th grade English Language Learners. The students who participated in the Read 180 program scored below the 25th percentile on the Florida Comprehensive…

The present study examined the outcomes of a newly designed four-lesson science module on opinion-forming in the context of genomics in upper secondary education. The lesson plan aims to foster 16-year-old students' opinion-forming skills in the context of genomics and to test the effect of the use of fiction in the module. The basic hypothesis…

This paper proposes a multimedia English learning (MEL) system, based on Hidden Markov Models (HMMs) and mastery theory strategy, for teaching students with the aim of enhancing their English phonetic awareness and pronunciation. It can analyze phonetic structures, identify and capture pronunciation errors to provide students with targeted advice…

This study investigates the effects of a scientific literacy strategy which focuses on reading, writing, talking and doing science on the development of grade six and seven learners' general literacy skills, both in their home language (isiXhosa) and the language of classroom instruction (English). A mixed method design was used. Quantitative data…

The 4Rs Program (Reading, Writing, Respect and Resolution) is a "dual focus" whole school universal intervention designed to promote literacy development and social-emotional learning, that is currently being rigorously evaluated using a school-randomized trial of 18 elementary schools (9 intervention, 9 control) in New York City.

The purpose of this study was to examine the effects of teacher mediation on the mathematics learning of kindergarten students in a computer-assisted learning environment. A sample of 26 students was randomly selected and assigned into experimental and control groups. The experimental group was mediated by a teacher during the computer-assisted…

A mini-lesson in Spanish vocabulary was taught to undergraduates unfamiliar with the language using one of two predominant L2 teaching methodologies, the grammar-translation approach or the communicative approach. Both experimental groups showed significant improvement in learning the target language over the baseline measure set by the control…
