While online and face-to-face (F2F) courses have been compared in numerous studies, there has been a lack of focus on online chemistry courses. This study was conducted to compare the success of students instructed in an online or F2F general chemistry course for non-majors. One hundred forty six exam questions were categorized according to…

This study compared obtrusive observers and self-reports to a criterion, unobtrusive observers, to assess how accurately they measured tutor performance. Unobtrusive observers were used as a criterion for comparison because it was assumed that their measures were free of biases. Participants were 55 college-level peer tutors. Course sections were…

This paper reports on a study involving the administration of two examinations that were designed to evaluate student knowledge in several areas of computing. The tests were given both to computer science majors and to those enrolled in computer science classes from other majors. They sought to discover whether computer science majors demonstrated…

Two studies involving 274 Air Force recruits and 163 college students, respectively, investigated the relationship between priming effects and declarative knowledge acquisition within repetitive practice models. Individual differences in repetition-priming effects uniquely predicted learning differences relative to other cognitive measures.…

This study assessed the sports nutrition knowledge of current and prospective physical educators/coaches (HPEs) to determine the need for improved education in this area and to compare the nutrition knowledge of HPEs with that of foods and nutrition students (FNSs) and general college students (GENs). A researcher-developed 4-point Likert-type…

Two experiments with approximately 377 newly enlisted Air Force personnel and 182 college students investigated the validity of a reading span test combining a knowledge verification task with a word memorization task. Results support the hypothesis that word recall reflects the amount of working memory functional in reading. (SLD)

Results for 78 college students who took a pretest on basketball knowledge, read a passage on basketball, and took an immediate or delayed posttest indicate that pretest scores are significantly related to immediate posttest scores, whereas delayed posttest scores are related to Scholastic Aptitude Test verbal scores. (SLD)

Cognitive changes in college students from early in the freshman year to the end of the sophomore year were assessed using a pretest-posttest design. In all, 135 university students completed both a pretest and a posttest. The academic achievement measure used was the College Basic Academic Subjects Examination (CBASE), a test intended to assess…

Studied the effects of implicit instruction, explicit instruction, and values clarification instruction. All treatment groups reported significantly higher knowledge scores than did the control group, but only the explicit instruction treatment was able to produce any changes in attitudes or behavior.

The understanding of children and adults regarding four component properties of the arithmetic mean was studied. The component properties were: (1) the mean is a data point between extreme values of a score distribution; (2) the sum of deviations about the mean equals zero; (3) when the mean is calculated, any value of zero must be taken into…
