Argumentative thinking requires not only the "skill" to apply argumentative strategies such as supporting theories with evidence but also the "will" to apply these strategies by considering argumentative thinking to be both reasonable and worthwhile. Focusing on direct instruction for the initial acquisition of both skill and…

The objective of this work was to promote a closer relationship between students who never had contact with a scientist. Two simple questions were selected to be answered experimentally in the school laboratories: How important are the pigments in plants? Which molecules make up the food? Two Scientists from UFRJ, who research in these areas,…

Students training to become primary school teachers appear to have little awareness of the core concepts of geography (teaching). To ensure that future primary school teachers are able to develop their pupils' geographical awareness, a six weeks programme was developed. The characteristics of this programme -- named Consciously Teaching Geography…

Project GOAL is a systematic dropout prevention model including individual and peer-mediated group interventions for at-risk students. This article provides an overview of the Project GOAL model and describes a 2-year experimental pilot study of Project GOAL with a cohort of eighth-and ninth-grade students in a low-income school district in the…

The purpose of this study was to determine the effects of specific practice strategy use on university string players' performance. Participants ('N" = 40) volunteered for the study and were string players enrolled in orchestra at a major research university. Within a pretest-posttest designed study, participants were assigned to one of four…

This study investigated the effectiveness of oral metalinguistic feedback and recasts as well as the effect of focused tasks (FT) in the development of implicit and explicit knowledge during video-conference interactions. This was accomplished by partial replication of a study performed in a classroom setting. Three groups of Brazilian EFL…

Districts expend a considerable amount of time, effort, and resources providing student performance data to teachers to inform instruction, and examining those data for organizational decision-making. Yet rarely, if ever, are these outcome data connected to what goes on in classrooms. In this experimental study, the author reports on the…

This paper argues that Educational Effectiveness Research (EER) should establish closer links with research on teacher professional development. A dynamic integrated approach (DIA) to teacher professional development is proposed. The methods and results of a study comparing the impact of the DIA and the Holistic Approach (HA) to teacher…

This experimental study investigated whether computer-based video games facilitate children's cognitive learning. In comparison to traditional computer-assisted instruction (CAI), this study explored the impact of the varied types of instructional delivery strategies on children's learning achievement. One major research null hypothesis was…

Described is a study designed to test on a scientific basis the effectiveness of Dr. Francis Christensen's program for teaching composition. (RY)

An experimental program in which regular General Mathematics 9, 10, and 11 courses were supplemented by instruction in business machines was evaluated. Results of the Test of Mathematical Fundamentals and the Mathematics Test Supplement (see sample, Appendix A) showed no significant superiority in achievement for students in the experimental group…

This experimental study examined the influence of a classwide peer-tutoring reading program (Peer-Assisted Learning Strategies; PALS) on the quality of social relationships of elementary school children. Using a sociometric procedure, social preference and friendships were evaluated before and after the PALS program. Overall (mean) and…

To assess gain and retention of televised agricultural information and its relation to other characteristics such as farmers' age, land ownership, and education, an experiment using a before-after design was conducted in a rural area of India covered by the Satellite Instructional Television Experiment (SITE) program.

The experimental pilot project was conducted to determine whether students who take the laboratory phase of an engineering technology applied electricity course in a mobile laboratory at branch schools demonstrate proficiency comparable to students who take the applied electricity course in permanent facilities at the parent institution. The…

This document is an English-language abstract (approximately 1500 words) of a new approach to the teaching of mathematics in Mexican elementary schools. Three aspects of mathematical reform are discussed: (1) syllabus content; (2) teaching methods; and (3) the question of introducing the pupil to modern mathematics at the earliest possible stage…
