Equating Error and Statistical Bias in Small Sample Linear Equating

A resampling study was conducted to compare the statistical bias and standard errors of nonequivalent-groups linear test equating in small samples of examinees. Sample sizes of 15, 25, 50, and 100 were examined. One thousand samples of each size were drawn with replacement from each of 5 archival data files from teacher subject area tests. For each test, data files from 2 parallel forms were used. Results suggest trivial levels of equating bias even with small samples, but substantial increases in standard errors as sample size decreases. Results were interpreted in terms of applications to testing situations in which small numbers of examinees are available.     

An Empirical Investigation of the Efficacy of Multimedia Instruction in Counseling Skill Development

The purpose of this study was to examine the effects of multimedia instruction on students' counseling skill development. The participants were 73 beginning‐level counselor education students (20 men and 53 women, ages ranging from 24 to 47 years). Ratings of students' pre‐ and posttest video counseling tapes were used to assess the effects of the multimedia approach. The results found that there was no statistically significant difference among the levels of students' counseling skill development across the 3 (high‐tech multimedia, low‐tech multimedia, and traditional instruction) treatment groups.     

Remembering Activities Performed Versus Imagined: A Comparison of Children with Mental Retardation and Children with Normal Intelligence

CHILDREN with mental retardation and children with normal intelligence were asked to perform a series of tasks or to only imagine performing them. They were then asked to remember which tasks had been performed and which had been imagined at an immediate interview and after an eight week delay. There were no overall differences between the two groups in the number of correct responses. However, all children gave more correct responses to specific probes than to open‐ended probes and remembered activities performed better than those imagined. Performance was more accurate for both groups at the immediate interview than at the delayed interview. Responses to questions about activities neither performed nor imagined were good for both groups of children to the initial questions but decreased significantly in response to a follow‐up probe. Accuracy of responses to these misleading questions decreased over the eight week delay.     

Teaching Hypertext Composition

Composing hypertext documents can be an enriching path into the world of technical communication. In learning to produce hypertext, students are introduced to an important form of written composition that encompasses not only text generation, but also visual communication and information architecture. In this article, I provide a rationale for teaching hypertext composition and then some specific curricular suggestions in two parts, one for teaching beginners, and one for teaching more advanced students.     

Computer Technology,Science Education,and Students with Learning Disabilities

The ways computer technology could be used to teach science to students with learning disabilities (LD) are explored. Science is for all students and that includes students with LD. Learning science has both cognitive and affective implications for students with LD. In this context, computer technology provides cognitively engaging and motivating instructional tools for individualizing the mode of delivery; developing expert tutors; anchoring instruction; integrating science with other subjects; reducing cognitive load on working memory; and motivating students to stay on task. These applications are discussed with implications for teaching science to students with LD.     

A study of the validity of four types of student ratings of college teaching assessed on a criterion of student achievement gains

The purpose of the study was to investigate relationships between student ratings of college teaching using four types of student rating instruments and pre- vs. post-student achievement gains in 36 sections of an undergraduate analytic geometry and calculus course. Student rating instruments used varied according to type of items (high vs. low inference) and focus (students rating their own perceived growth vs. rating the instructor). Data were collected on 799 students (66% freshmen; 16% sophomore; and 15% juniors) at the University of Florida, and relationships were analyzed using the Pearson product-moment correlation technique. Significant relationships were not found between student ratings and student achievement.     

Ratings by Counselors Without Teaching Experience And Their Principals Regarding Performance of Guidance Functions

This study compared principal and self ratings of performance of guidance functions for practicing counselors who did not have teaching experience. The sample consisted of 43 counselors and their principals from throughout the United States. The ratings indicate better-than-average initial counselor acceptance by administrators, teachers, students, and parents with the degree of acceptance being greater after they had counseled for a while. Principal and self ratings differed significantly on initial acceptance by students and present acceptance by other counselors. Ratings of acceptance by both school psychologists and social workers were below average. There was no significant difference in counselor and principal ratings of counselor understanding of various school procedures and policies or of their ability to perform basic guidance activities. A majority of the principals who had worked with the counselors with non-teaching backgrounds indicated they would recommend the hiring of such a person to their school board.
