We analyze results from paired pre- and post-instruction administration of the Mechanics Baseline Test to 2238 students in introductory mechanics classes. We investigate pairs of specific wrong answers given with unusual frequency by students on the pretest. We also identify transitions between pre- and post-test answers on the same question which…

In response to calls for research into effective instruction in the Earth and space sciences, and to identify directions for future research, this systematic review of the literature explores research into instructional approaches designed to facilitate conceptual change. In total, 52 studies were identified and analyzed. Analysis focused on the…

This study examined the extent to which school outdoor activities could enhance senior secondary (SS) two students' achievement in ecology. Non randomized pre test post test control group Quasi-experimental design was adopted. A sample of 160 SS II students from 4 co-educational schools in Jalingo metropolis, Taraba State Nigeria was used. A 40…

Objective: This study examined the feasibility of using wireless mobile devices (MDs) to collect daily alcohol information among college students, in particular examining feasibility in the context of costs associated with the use of wireless MDs. This study reports on practical aspects of using MDs to collect alcohol data, including compliance,…

Clickers were used for real-time data collection in two introductory biology laboratory courses so that students could perform statistical analysis on large data sets. Student attitudes toward this use of clickers were surveyed and students were administered a pre- and posttest on statistical content. Capture of large data sets allowed instructors…

Objective:This report extends earlier accounts by addressing the effects of the Strong African American Families (SAAF) program across 65 months. Two hypotheses were tested: (a) Rural African American youths randomly assigned to participate in SAAF would demonstrate lower rates of alcohol use than would control youths more than 5 years later, and…

In previous publications the author reported on the use of a website dedicated to French songs for an advanced French comprehension course at the university level. The present article analyzes web-tracking data captured from the website over two terms--fall 2003 and winter 2004. The variations in the amount of time students spent working on the…

This paper explores the role of organising data in representing numerical data in an organised way--a skill which does not come naturally to most students. Grade 6 children were given a series of lessons on organising data and then representing the data graphically. It was found that after instruction, more students were able to reorganise the…

A performance evaluation model is presented to address the need for measuring the effectiveness of educational training programs in institutions of higher learning. The model emphasizes outcomes by assessing the quality of change that occurs in individual and program performance. (Author/LMO)

Because a lack of adequate data eliminated the possibility of using control groups or historical comparison groups, Colorado's procedure for evaluating state bilingual/bicultural programs was designed to determine whether children in the bilingual program (K-3) had learned more than they would have learned if they had not been in the program. A…

This feasibility study explored the automated data collection, scoring, and reporting of children's complex problem-solving processes and performance in Web-based information-rich environments. Problem solving was studied using realistic problems in realistic contexts demanding multiple cognitive processes in the domain of environmental science.…

The return on investment (ROI) obtained by enterprises that invest in training was examined through case studies of seven Australian work organizations. The case study organizations included a government-owned transportation company, a privately owned company, a major nongovernmental charitable organization, a publicly listed corporation, and two…
