The construct validity of four self-concept (SC) traits (general SC, academic SC, English SC, mathematics SC), as measured by three different scales (Likert, semantic differential, Guttman) for low- (n=252) and high-track (n=588) Canadian high school students, was assessed using both the Campbell-Fiske criteria, and a comparison of hierarchically…

One of the most frequently used research methods in education and psychology involves repeated observations on the same individuals. When sample sizes are relatively small and a multivariate analysis lacks power, there are currently two analytical options in testing time effects. One is to assume a time series structure to these observations, and…

This paper examines differences in educational outcomes among 1,792 students from small (fewer than 300 pupils), average (400-700 pupils), and large (900-1,200 pupils) rural high schools, and among 1,084 students from small high schools in urban, suburban, and rural settings. Data were drawn from the High School and Beyond database, a national…

The advantages of applying confirmatory factor analysis (CFA) to multitrait-multimethod (MTMM) data are widely recognized. However, because CFA as traditionally applied to MTMM data incorporates single indicators of each scale (i.e., each trait/method combination), important weaknesses are the failure to: (1) correct appropriately for measurement…

This report explores the student background characteristics that might be associated with success or failure in calculus and evaluates the effectiveness of remedial mathematics education. The sample consisted of two groups at the University of California, Santa Cruz: (1) all students (105) who took first quarter calculus in spring, 1985; and (2)…

A study of one grade cohort of students taught in a Chicago Mastery Learning Reading (CMLR) Program was extended to two additional cohorts, one older and one younger than the original group but who were taught using the same method. The students' reading comprehension test scores were compared with those of students in other schools, not taught by…

The results of two experimental studies of interference in German-Swedish bilingual and trilingual high school students are presented. Both were developmental studies with length of residence in Sweden as the main independent variable. The purpose was to follow the developmental changes in intra- and interlingual interference and to find out if…

If a student is to develop reading comprehension, he must possess and activate a number of linguistic and cognitive skills. He comes to the text with certain expectations and uses a cyclical process of sampling, predicting, testing, and confirming to understand it. The overall goal of reading instruction is to produce motivated, independent,…

To examine the validity of short forms of the Wechsler Intelligence Scale for Children-Revised (WISC-R), the WISC-R was first administered to 106 hospitalized psychiatric patients, aged 8-16. No subjects had a primary diagnosis of mental retardation or learning disability, and one-third were receiving psychotropic medication. WISC-R IQ scores…

This study examined the need to develop reliable and valid procedures for screening large populations for possible speech and language problems and the use of the Fluharty Preschool Speech and Language Screening Test (FPSLST) as such a device. The test was administered to 260 preschool children, ages three to six. There were 166 Blacks and 94…

This study examined the effects of feedback (immediate, delayed, or no feedback) and the type of control (external or internal) on computer-assisted instruction (CAI), and also considered the influence on achievement of such factors as computer anxiety, self-concept, learning style, and gender. Subjects were 336 undergraduates, the majority of…

A study investigated the levels of language proficiency and language anxiety of English-as-a-Second-Language (ESL) learners. The goals of the study were: (1) to determine the effect of gender differences and learner specialization on levels of English language anxiety; (2) to study the relationship between gender differences and academic…

A study conducted at the University of Maryland, College Park campus compared the effectiveness of three instructional media for presenting introductory training in the use of an online circulation system. Modules based on a common set of instructional objectives and examples were developed and delivered using three formats: a print packet, a…

Purposes of this study were: (1) to examine patterns of implementation of an innovative educational program with a built-in staff development component over a period of three years; (2) to compare patterns of implementation of the Adaptive Learning Environments Model's (ALEM) three types of teaching skills, including generic, adaptive, and program…

School effectiveness indices (SEIs) based on residuals from regressing test performance in reading and mathematics onto prior-year test performance and a socioeconomic status measure (percentage eligible for a subsidized lunch program) were obtained for two consecutive years for 431 South Carolina elementary schools. The analysis involved school…
