Eight models that can be used to analyze data from a pretest-posttest design are discussed. Artificial data are used to demonstrate that comparisons among some of the models generate results identical to those obtained by using repeated analysis of variance measures. Such results are shown to be potentially misleading. (Author/TJH)

In three Iowa secondary schools, pretests/posttests were completed by 75 physics students, 24 second-year Principles of Technology (PT) students, and 61 controls. Physics and PT students significantly increased achievement in content covered in PT; controls had no gains. PT students' raw scores were 16 points higher on the posttest than physics…

Following the…

Geometry is the study of shape and space. Without spatial ability, students cannot fully appreciate the natural world. Spatial ability is also very important for work in various fields such as computer graphics, engineering, architecture, and cartography. A number of studies have demonstrated that technology has an important potential to develop…

Drama at primary teaching course is given as a compulsory course to students enrolling department of the primary teaching in college of education in Turkey. In drama, assessment is problematic as the content of the lesson often deviates from the plan because of spontaneous input from the students and on-the-spot changes in direction by the…

The aim of the study was to determine whether the animation of a linear process, requiring explanatory text, can assist students to form a better understanding of the text. Tertiary students (N = 61) participated in a pre-test, post-test experimental study during which they were exposed to 4 treatment variables: text (T), video and text (VT),…

The objective of the study is to determine if there is a significant difference in the effects of the treatment and control groups on achievement as well as on attitude as measured by the posttest. A class of 38 sophomore college students in the basic statistics taught with the use of computer-assisted instruction and another class of 15 students…

Eighty-one pairs of concepts maps were scored according to established methods. Students…

Spatial ability, which is positively correlated with retention and achievement in engineering, mathematics, and science disciplines, has been shown to improve over the course of a Computer-Aided Design course or through targeted training. However, which type of training provides the most beneficial improvements to spatial ability and whether other…

To understand evolutionary theory, students must be able to understand and use evolutionary trees and their underlying concepts. Active, hands-on curricula relevant to macroevolution can be challenging to implement across large college-level classes where textbook learning is the norm. We evaluated two approaches to helping students learn…
