The study investigated cultural bias in the 79 items of the three verbal tests of the Wechsler Intelligence Scale for Children-Revised (WISC-R). The Information, Similarities, and Vocabulary subtests were administered to 40 Anglo and 40 Native- American Navajo subjects matched for grade level. The responses of the two groups of subjects on individual items were analyzed by log-linear technique using the likelihood ratio chi-square statistic. The findings revealed that performance of subjects was homogeneous across groups on most of the items of three verbal subtests of the WISC-R. Only 15 (19%) of the 79 items comprising Information, Similarities, and Vocabulary subtests were found to be biased against the Navajo sample. Five of these items are from the Information, four from the Similarities, and the remaining six items are from the Vocabulary subtest. Implications of these findings for the psychoeducational assessment of minority children were discussed.  相似文献

Abstract

This study investigated the relationship between teachers’ levels of Inferred Self Concept (ISC) and the cognitive growth of their students. One hundred twenty third grade students were matched for sex and IQ, and their cognitive growth was determined by pre and post testing with the Word Meaning, Paragraph Meaning, Spelling, Word Study Skills, and Language sub tests of the Stanford Achievement Test. The six teachers levels of ISC were determined by three raters who completed Parker’s Self Concept Checklist after observing each teacher for one hour. The levels of ISC were related positively to the students’ cognitive growth at the .01 level of significance for four of the five subtests and the total gain.  相似文献

A sample of 46 white fourth-grade pupils was administered the PPVT, WRAT, and PIAT, except for PIAT Reading Comprehension and General Information. Subjects were selected randomly from those pupils whom classroom teachers judged to be doing at least average academic work. Mean grade equivalents, as well as intercorrelations, were examined for PIAT and WRAT subtests. No sex differences were found for PPVT IQ, age, or most achievement scores. Mean grade equivalents generally ranged between the sixth-and seventh-grade levels. Nearly all PIAT-WRAT intercorrelations were positive and significant, and highest for the similarly labelled subtests. Substantial differences were noted in mean grade equivalents. WRAT Reading and Spelling exceeded their PIAT counterparts by approximately one grade level. In contrast, PIAT Mathematics exceeded WRAT Arithmetic by more than one grade level. The possible effects of differences in item content and task structures on performance were discussed. Implications for practitioners involved in psychoeducational evaluations were considered.  相似文献

The study was conducted to explore performance on a variety of mental computation tasks using two presentation formats (visual and oral). Students at four grade levels between grades 2 and 9 in three countries (Australia, Japan, United States) were given a group administered mental computation test consisting of two parts (oral presentation format, visual presentation format).The sample of nearly 2000 students represents 6 classes at each of four grade levels in each country. Results indicate a wide variation in performance within the sample of each country at each grade level. Differences in performance between countries are also apparent and may reflect variations in instructional focus on mental computation. In particular, Japanese students perform at a higher level at the early grades than do students in either of the other countries sampled. However, by grade 8 this difference narrows in the American sample, and vanishes for the Australian sample. Differences in performance related to presentation format were dramatic for particular items and non-existent for other items. The most consistent effect was found in the Japanese sample where the visual presentation format resulted in higher performance levels on most items.It is hypothesised that superior results on visually presented items are attributable to a greater reliance on use of the standard written algorithm, while superior results on orally presented items indicate a greater tendency to use invented mental algorithms.  相似文献

Two group paper-pencil batteries, the Longeot (consisting of three subtests) and three puzzles (KLR) from Science Teaching and the Development of Reasoning, were administered to 607 students from ninth and tenth grade mathematics and science classes. A subsample of 69 students was then administered three Inhelder tasks (chemicals, rods, and shadows). In general, the expected developmental trends were confirmed, with formal status being most difficult to attain on the Inhelder tasks and easiest to attain on the Longeot. The correlations between the KLR and Inhelder (0.61, p < 0.01) and the Longeot and Inhelder (0.55, p < 0.05) were moderately high. According to the method of Shayer (Note 2), it was found that each of five paper-pencil subtests discriminates at or between the 2B (late concrete) and 3A (early formal) levels while the sixth subtest, the mealworm puzzle, was found to discriminate at the 3A level. This study indicates that either group battery may be useful in identifying transitional subjects. However, if a more stringent criterion of “formal” is needed, a “success” rate of four or five out of the six subtests may be required. Both group batteries are relatively easy to administer and score with a minimum of guidance, although the KLR scoring might need to be simplified for use by the practitioner. Sex differences found on the KLR and the Longeot are suggestive of the potential differential use of these tests by researchers investigating sex differences in achievement or aptitude.  相似文献

In a long-term study of student progress in the Loyola University of the South Summer Reading Clinic, patterns of variance for sex and grade level were examined. Three assessment tools were used: the Nelson Reading Test (Vocabulary and Paragraph Comprehension) for grades four through eight, the Gates-MacGinitie Reading Test (Vocabulary and Comprehension) for grades one through three, and the Spache Diagnostic Reading Scales (Instructional [oral] and Independent [silent] subtests) for all students. Subjects were 684 public and private school students in grades one through eight referred to the Clinic over an eight-year period. All were referred for possible reading disabilities. Because reading disabled males outnumber reading disabled females in the general population, the Clinic's data were examined to elucidate the comparative success rates of boys and girls in an intensive reading clinic setting. Grade differences also were examined to find significant differences in rate of learning among different grades. Females outscored males significantly on all measures. Both a difference in performance among grades and a difference in rate of learning among grades were shown.  相似文献

This article describes a comparative study conducted at the item level for paper and online administrations of a statewide high stakes assessment. The goal was to identify characteristics of items that may have contributed to mode effects. Item-level analyses compared two modes of the Texas Assessment of Knowledge and Skills (TAKS) for up to four subjects at two grade levels. The analyses included significance tests of p-value differences, DIF, and response distributions for each item. Additional analyses investigated item position effects and objective-level mode differences. No evidence of item position effects emerged, but significant differences were found for several items and objectives in all subjects at grade 8 and in mathematics and English language arts (ELA) at grade 11. Differences generally favored the paper group. ELA items that were longer in passage length and math items that required graphing and geometric manipulations or involved scrolling in the online administration tended to be the items showing mode differences.  相似文献

The present study attempted to extend our knowledge of the role of reading fluency in contributing to reading comprehension among Turkish students in grades 4 through 8. One hundred students at each grade level were administered assessments of reading fluency, word recognition automaticity and prosody, and silent reading comprehension. Word recognition automaticity was found to be a significant predictor of comprehension at all grade levels tested. Prosody predicted comprehension at all grades levels except grade 4. Regression analyses at each grade level indicate that, except for grade 4, word recognition automaticity and prosody, together contribute to the prediction of reading comprehension. The magnitude of fluency’s prediction of comprehension ranged from approximately a quarter to a third of comprehension. The results are discussed in terms of policy and instructional changes that may be considered for reading instruction for Turkish students.  相似文献

Students’ value beliefs tend to decrease across secondary school (Wigfield et al., 2015). However, previous studies did not differentiate between all the dimensions of task values defined by expectancy-value theory (Eccles et al., 1983). Therefore, this study evaluated an instrument for assessing multiple value dimensions across grade level and academic subjects and tested for differences between grade levels in these subjects. A total of 830 students from Grades 5 to 12 completed a questionnaire assessing their value beliefs in German, English, math, biology, and physics with 37 items each. The factor structure was shown to be invariant across academic subjects, grade levels, and gender. Generally, students in higher grades showed lower means on positive value facets and higher means on cost facets. However, the results varied substantially by facet and subject. Furthermore, stereotypical gender differences in value beliefs were found, and some of these differences increased with students’ grade level. The findings indicate that examining multiple dimensions and subjects is crucial for developing a complete understanding of the development of students’ value beliefs.  相似文献

The purpose of this study was to investigate the mathematics components of an achievement battery for differential item performance between boys and girls. By employing a longitudinal study, changes in differential item performance from Grades 4 to 6 were explored, thereby avoiding confounding of age and cohort differences. Two statistical procedures were employed to investigate differential performance at both the test and item level (Spearman's rho and Camilli's chi-square). Items in two mathematics subtests, Mathematics Computation (MC) and Mathematics Concepts and Applications (MCA), did not appear to be a source of sex-related bias. Girls scored higher than boys on MC subtest across grades. Boys scored higher than girls across grades on MCA subtest. However, there were no skill classifications, ability levels, or item locations that favored one sex group consistently across grades.  相似文献

The reading achievement of at-risk first, second, and third grade students participating in a systematic, sequential, multi-sensory, synthetic, phonetically-based approach to reading (Project Read) was compared with that of control group students instructed through the use of traditional basal readers. Data were analyzed for both the full study and a sub-group in which the teacher variable was controlled. Significant differences were found at first grade for all subtests and the total reading achievement of treatment group students. First grade students reached achievement levels thought possible only through tutoring.  相似文献

Information about how success and gender affect students' views of ideal and actual classroom role behavior can help both researchers and teachers better understand classroom components such as achievement and curriculum. A 20-item double Q sort was used to measure differences in perceptions of high school science students according to letter grades and gender. Individual Q sort item rankings of 160 students were tested for significant differences according to letter grade received; item ratings were compared according to gender for 215 students. Differences in perception according to success were found for both ideal and actual behavior; 8 and 5 items, respectively, out of each 20-item sort were found to be significant at the p = < 0.05 level. No such overall patterns of difference in view were found between boys and girls, although three ideal student items and one actual self-report item were found to be significantly different at the p = < 0.05 level.  相似文献

The purpose of this study was to determine whether adjustments for the differential prediction observed among sex, racial/ethnic, or age subgroups in one freshman class at a college could be used to improve prediction accuracy for these subgroups in future freshman classes. For older students, dummy variable and separate subgroup prediction equations were found, on cross-validation, to be more accurate than the total group equations. For sex subgroups, dummy variable and separate subgroup equations were only moderately effective in improving prediction accuracy. For racial/ethnic subgroups, they were more often than not less accurate, on cross-validation, than total group equations. Among all three kinds of demographic subgroupings, shifts over time in colleges' mean grade averages were found to be a more important source of prediction bias than differential prediction.  相似文献

In laboratory studies, induced stereotype threat shows negative effects on academic performance and learning. Is the relation between stereotype threat and grades robust in naturalistic settings, specifically in introductory STEM courses? We gathered data on two new measures we term race and sex stereotype bias, which were administered four times over the course of introductory chemistry and biology courses for STEM majors (N = 1358). Patterns of growth for all stereotype bias measures showed a discontinuous pattern, with increases during each semester (fall and spring) and decreases between semesters. For all stereotype bias measures, sophomores scored significantly higher than freshmen, and juniors scored in between. For the sex stereotype bias measure, females scored significantly higher than males. There were no race or sex differences on slopes of growth; though groups began at different levels, all grew at the same rate. There was little relation between grades and stereotype bias when analyzed by race; Asian students showed the largest number of significant – albeit small – correlations (3) and Black students the fewest (none). Correlations between grades and sex stereotype bias were significant and negative – but small – only for males. Results support a point made by Steele in 1997 but neglected since then; stereotype threat may affect only a small sub-portion within stereotyped groups. We argue that variables other than stereotype threat might be better targets for research attempting to explain gaps in STEM achievement and retention.  相似文献

This study examined whether male students dominated classroom interactions in home economics lessons and whether other classroom processes sustained gender divisions in this subject in two Form I and two Form II classes in two schools. The sample included two female home economics teachers and all the students in the four classes (34 boys and 31 girls). Data were collected during five 60‐minute observation sessions in each class (inter‐observer reliability reached 94%) and structured interviews with both teachers and 24 students (three boys and three girls from each class). Statistically significant (p < 0.001) differences were found in the number of times students were helped by the teachers (boys received 76% of teachers’ help) and in the number of reprimands they received (boys received 87%). Boys and girls received a comparable amount of praise but boys received a greater amount of interaction in all other categories (direction of teacher questions, choice of students to answer questions, call‐outs and calling students by name) although these differences were not statistically significant. There were major individual differences between students of the same sex in all the categories. More boys (19) than girls (seven) were high participants in different classroom processes. Most of the students in mixed‐gender kitchenettes co‐operated in cleaning up. Teachers expected the same standard of work from all the students but they allotted more special jobs to girls.  相似文献

Abstract

This study was an investigation of items on the Peabody Picture Vocabulary Test (PPVT) to ascertain if verbal responses to items missed indicated that the concept was familiar at the same level of abstraction as the word in the PPVT. One hundred 8-year-old children-25 black boys, 25 black girls, 25 white boys, and 25 white girls-were administered Form A of the PPVT. Eighty-eight children responded verbally to the pictures of the stimulus words missed. Data were analyzed by means of a two-way analysis of variance. A chi square test of significance was used to determine significance level of difference between items for each group. Judges analyzed verbal responses to determine if responses elicited were 1) at the same level of abstraction as the stimulus word, 2) considered to be synonymous to the stimulus word, and 3) indicated the student's understanding of the concept signified by the word. A total of 23 words were identified as being missed disproportionately by one group more than the other. Verbal responses indicated that the concept was familiar for 16 items and unfamiliar for three items. Of the remaining four items, there was indication of differences among the groups.  相似文献

The present study investigated whether gender differences were present on the confidence judgments made by 8th grade Taiwanese students on the accuracy of their responses to acid–base test items. A total of 147 (76 male, 71 female) students provided item-specific confidence judgments during a test of their knowledge of acids and bases. Using the correctness of the answer responses, a confidence rating score, an unweighted rating score, and a relative confidence rating score were calculated for each respondent. The correlations between the boys and girls for each score area showed girls as scoring higher than boys in their knowledge of acids and bases, were more confident in this knowledge, and more willing to express different levels of confidence among the test items.  相似文献

The study investigated the significance of matching cognitive style of first- and third-grade students to their teachers. The Articulation of the Body-Concept Scale was administered as a measure of cognitive style to 20 first- and 20 third-grade female teachers and a sample (480) of six boys and six girls for each teacher. Teachers ranked their students according to their judgment of the students’ academic competence. Discrepancy scores were obtained based on the degree to which teachers differed in ranking their students in comparison to rankings on the Comprehensive Tests of Basic Skills. A repeated measures analysis of variance indicated statistically significant main effects for grade level and a statistically significant interaction among the cognitive styles of teachers in ranking their matched and mismatched students according to sex in relation to the students’ academic achievement scores.  相似文献

The sex role attitudes of 461 teacher education students were measured on a 32‐item questionnaire. Chi‐square analyses produced significant effects for gender on 22 of the items, showing that the females were more egalitarian than the males. However, most of the students adopted an egalitarian stance on many, though not all, of the items. Responses to some items (women getting drunk and swearing, corporal punishment, boys doing heavy chores, and boys dressing up and playing with dolls) suggest that some traditional stereotypes may be particularly resistant to change. The data also suggest that students may adopt egalitarian attitudes out of self‐interest rather than as a matter of principle, and are more accepting of general principles of gender equity than of specific practices designed to achieve it. Finally, although there is some evidence of ambivalence among the students, particularly the males, it is more accurate to characterise these students as definite in their gender attitudes.  相似文献

The purpose o f this study was to examine the consistency with which students applied procedural rules for solving signed-number operations across identical items presented in different orders. A test with 64 open-ended items was administered to 161 eighth graders. The test consisted o f two 32-item subtests containing identical items. The items in each subtest were in random order. Students'responses to each subtest were compared with respect to the identified underlying rules o f operation used to solve each problem set. The results indicated that inconsistent rule application was common among students who had not mastered signed-number arithmetic operations. In contrast, mastery level students, those who use the right rules, show a stable pattern o f rule application in signed-number arithmetic. These results are discussed in light of the hypothesis testing approach to the learning process.  相似文献
