Using data from a sample of 10 colleges at which most students had taken both SAT I: Reasoning tests and SAT II: Subject tests, we simulated the effects of making selection decisions using SAT II scores in place of SAT I scores. Specifically, we treated the students in each college as forming the applicant pool for a more select college, and then selected the top two thirds (and top one third) of the students using high school grade point average combined with either SAT I scores or the average of SAT II scores. Success rates, in terms of first-year grade point averages, were virtually identical for students selected by the different models. The percentage of African American, Asian American, and White students selected varied only slightly across models. Appreciably more Mexican American and Other Latino students were selected with the model that used SAT II scores in place of SAT I scores because these students submitted subject test scores for the Spanish test on which they had high scores. 相似文献

The prevalence of homeschooling in the United States is increasing. Yet little is known about how commonly used predictors of postsecondary academic performance (SAT, high school grade point average [HSGPA]) perform for homeschooled students. Postsecondary performance at 140 colleges and universities was analyzed comparing a sample of traditional students matched to a sample of 732 homeschooled students on four demographic variables, HSGPA, and SAT scores. The matched sample was drawn from 824,940 traditional students attending the same institutions as the homeschooled students, which permitted a very precise level of matching. This comparison did not show a difference in first‐year college GPA (FGPA) or retention between homeschooled and traditional students. SAT scores predicted FGPA and retention equally well for both groups, but HSGPA was a weaker predictor for the homeschooled group. These results suggest that, among college students, those who were homeschooled perform similarly to traditionally educated students matched on demographics and academic preparedness, but there are practical implications for college admissions in the use of HSGPA versus standardized test scores for homeschooled students. 相似文献

In comparing the average scores for men and women on the Scholastic Aptitude Test (SAT, since revised and renamed as the Scholastic Assessment Test), sex differences in demographic and educational variables that influence test performance are usually ignored. In this study of 69,284 high school seniors (12th graders) who took the SAT in November of 1990, self-reported background information was used to compute adjusted scores for men and for women. On the Verbal section, the difference in observed means was 4.68 points while the difference in adjusted means was 9.87 points. On the Mathematical section, the difference in observed means was 45.38 points but the difference in adjusted means was 33.76 points (a reduction of over 25%). In all comparisons, the mean was higher for men than for women. It is argued that adjusted means may provide more appropriate comparisons of the performance of men and women on the SAT depending on the type of comparison to be made. 相似文献

A comparison, via path analysis, of educationally disadvantaged students (EOP) as participants and non-participants in an experimental section of a large introductory sociology course did not reveal significant differences in test performance. Given the great predictive strength of verbal SAT (r = .65) and the large differential in SAT scores between EOP and non-EOP students, it is argued that EOP performance, relative to that of the non-EOP majority, will not be significantly enhanced by this type of program. By contrast, it is shown that a substantial improvement is to be expected in the performance of future EOP students if the admissions policies were changed so as to admit students with higher verbal SAT scores. Some preliminary evidence indicates that with a smaller gap in verbal ability, it may be possible for compensatory programs to make a further contribution to the improved performance of disadvantaged students. 相似文献

The validity of the SAT as an admissions criterion for Latinos and Asian Americans who are not native English speakers was examined. The analyses, based on 1997 and 1998 UCSB freshmen, focused on the effectiveness of SAT scores and high school grade-point average (HSGPA) in predicting college freshman grade-point average (FGPA). When regression equations were estimated based on all students combined, some systematic prediction errors occurred. For language minorities, using only high school grades as a predictor led to predicted FGPAs that tended to exceed actual FGPAs, particularly for Latinos. Including SAT scores in the equation notably reduced prediction bias. Further analyses showed that, while HSGPA had the highest correlation with FGPA for most groups, SAT verbal score was the strongest predictor of FGPA for language minorities in 1998. An overriding conclusion is that combining data across language groups can obscure important test validity information. 相似文献

Extensive research has examined the validity and fairness of standardized tests in academic admissions. However, due to their underrepresentation in higher education, American Indians have gained much less attention in this research. In the present study, we examined for American Indian students (1) group differences on SAT scores, (2) the predictive and incremental validity of SAT over high school grades, (3) the effect of socioeconomic status on SAT validity, (4) differential prediction in the use of SAT scores, and (5) potential omitted variables that could explain differential prediction for American Indian students. Results provided evidence of predictive and incremental validity of SAT scores, and the validity of SAT scores was largely independent of socioeconomic status. Overprediction was found when using SAT scores to predict college performance and it was reduced when including high school grades as an additional predictor. This study provides substantial evidence of the validity and fairness of SAT scores for American Indians. 相似文献

Performance on the reading comprehension (RC) tasks of the Scholastic Assessment Test-I (SAT-I or the "new" SAT), the Enhanced American College Testing Assessment (ACT), and the Graduate Record Examination (GRE) when passages were missing was examined. For the SAT-I and ACT, scores were well above chance and correlated substantially with verbal score on the earlier version of the SAT, indicating that examinees perform similarly with or without passages. Comparable but weaker results were found for the GRE. The findings raise doubts about the construct validity of the RC task. We argue that performance is influenced by the plausibility of item choices with or without the passages and that this, in turn, is the result of the construction of test items with little knowledge of the underlying reading process. 相似文献

New measures of college selectivity 总被引：1，自引：1，他引：1
Institutional averages of entering freshman scores on the Scholastic Aptitude Test (SAT) and the American College Test (ACT) were combined and edited to produce a single institutional measure of selectivity for 2,601 institutions. Older scores were adjusted to reflect decreasing performance over time, and ACT scores were converted to SAT equivalents, resulting in a final measure that reflects 1973 performance levels and is expressed as an SAT Verbal plus Mathematical score (range 400–1,600). Actual scores were available for 1,803 schools; the remaining schools with missing values were given an imputed score based upon means from similar institutions among the 1,803. Correlations between scores from different years and between the final measure and 19 institutional attributes indicated substantial reliability and validity for the selectivity measure. 相似文献

Previous research has established that SAT scores and high school grade point average (HSGPA) differ in their predictive power and in the size of mean differences across racial/ethnic groups. However, the SAT is scaled nationally across all test takers while HSGPA is scaled locally within a school. In this study, the researchers propose that this difference in how SAT scores and HSGPA are scaled partially explains differences in validity and subgroup differences. Using a large data set consisting of 170,390 students each of whom matriculated at one of 114 separate colleges, the researchers find that awarding SAT scores by ranking SAT within a high school generally results in substantial reduction in the size of subgroup mean differences for this predictor. However, validity for predicting first‐year GPA is also reduced by a small amount. Conversely, placing HSGPA onto a nationally normed metric through the use of multiple regression procedures results in a moderate increase in the size of subgroup mean differences, while also producing a small increase in validity. Taken together, these findings suggest that differences in predictor scaling can partially explain differences in the size of subgroup mean differences between HSGPA and SAT scores and have implications for predictive power. 相似文献

As a first step in developing a model of academic dismissal, logistic regression was employed to analyze predictors of academic performance (academic dismissal versus satisfactory performance) for first-time freshmen after one semester in an eastern state university. The analyses for each of two entry years produced very similar results. The analyses indicated that academic performance was highly related to high school academic grade point average (gpa). After controlling for SAT Verbal and SAT Math scores and high school academic gpa, race and the academic grouping of the student's major were significantly related to academic performance. However, for students of a given race and in a given academic grouping with the same SAT Verbal scores, the same SAT Math scores, and the same high school academic gpas, there was no significant difference in the predicted probability of academic dismissal for (1) men and women students, (2) dormitory and commuter students, and (3) full-time and part-time students. 相似文献

The process employed to produce the conversions that take scores from the original SAT scales to recentered scales, in which reference group scores are centered near the midpoint of the score-reporting range, is laid out. For the purposes of this article, SAT Verbal and SAT Mathematical scores were placed on recentered scales, which have reporting ranges of 920 to 980, means of 950, and standard deviations of 11. (The 920-to-980 scale is used in this article to highlight the distinction between it and the old 200-to-800 scale. In actuality, recentered scores were reported on a 200-to-800 scale.) Recentering was accomplished via a linear transformation of normally distributed scores that were obtained from a continuized, smoothed frequency distribution of original SAT scores that were originally on augmented two-digit scales (i.e., discrete scores rounded to either 0 or 5 in the third decimal place). These discrete scores were obtained for all students in the 1990 Reference Group using 35 different editions of the SAT spanning October 1988 to June 1990. The performance of this 1990 Reference Group on the original and recentered scales is described. The effects of recentering on scores of individuals and the 1990 Reference Group are also examined. Finally, recentering did not occur solely on the basis of its technical merit. Issues associated with converting recentering from a possibility into a reality are discussed. 相似文献

Statistics is an important subject in psychology and social science education. However, inadequate mathematical skills can pose a barrier to learning statistics. Some educators have suggested that students’ math skills are declining. The present research examined trends in the math skills of psychology undergraduates across 21 years. Students (n = 3735) who were enrolled in an introductory psychology statistics course from 1990 to 2011 completed a pencil-and-paper math skills test. Over the 21-year period, there was a 9% decline in math skills scores and a 28% increase in the number of attempts required to pass the test. Consistent with national trends, SAT Math scores also increased by 7%; however, the pencil-and-paper math skills test was nearly twice as predictive of course performance as was the SAT. Results suggest that important math abilities have declined. Implications for statistical education in the social sciences are discussed. 相似文献

The determinants of state-wide average SAT scores are estimated for 1982 in a regression analysis which corrects for the proportion of students taking the test. The selectivity correction has a large impact on the estimates of the effects of other variables. Little effect of schooling variables (teachers' salaries, teachers per pupil, other expenditures) is found in the selectivity-adjusted estimates, except that large schools seem to depress SAT scores and private schools enhance scores. State-wide high school graduation standards also do not explain SAT score variation. In contrast, several demographic variables are quite important, including family size, the college-educated fraction of the population, and female-headed households. We can explain some of the SAT score decline in the 1970s with these cross-section estimates, suggesting that the decline over time is not due to changing resources for schooling but, in part, to changing demographics. In particular, a large part of the recent SAT score decline was caused by the large families of the post-war baby boom. 相似文献

In studies of the SAT, correlations of SAT scores, high school grades, and socioeconomic factors (SES) are usually obtained using a university as the unit of analysis. This approach obscures an important structural aspect of the data: The high school grades received by a given institution come from a large number of high schools, all of which have potentially different grading standards. SAT scores, on the other hand, can be assumed to have the same meaning across high schools. Our analyses of a large national sample show that, when pooled within-high-school analyses are applied, high school grades and class rank have larger correlations with family income and education than is evident in the results of typical analyses, and SAT scores have smaller associations with socioeconomic factors. SAT scores and high school grades, therefore, have more similar associations with SES than they do when only the usual across-high-school correlations are considered . 相似文献

Recent research has shown that admissions tests retain the vast majority of their predictive power after controlling for socioeconomic status (SES), and that SES provides only a slight increment over SAT and high school grades (high school grade point average [HSGPA]) in predicting academic performance. To address the possibility that these overall analyses obscure differences by race/ethnicity or gender, we examine the role of SES in the test‒grade relationship for men and women as well as for various racial/ethnic subgroups within the United States. For each subgroup, the test‒grade relationship is only slightly diminished when controlling for SES. Further, SES is a substantially less powerful predictor of academic performance than both SAT and HSGPA. Among the indicators of SES (i.e., father's education, mother's education, and parental income), father's education appears to be strongest predictor of freshman grades across subgroups, with the exception of the Asian subgroup. In general, SES appears to behave similarly across subgroups in the prediction of freshman grades with SAT scores and HSGPA. 相似文献

The goal of this study was to develop and evaluate a structural model of the relations among cognitive abilities and arithmetic skills and college students’ algebra achievement. The model of algebra achievement was compared to a model of performance on the Scholastic Assessment in Mathematics (SAT‐M) to determine whether the pattern of relations is similar for different types of higher level maths achievement. Structural equation modelling was used to test the effects of working memory, 3D spatial ability, and computational fluency on both types of higher order maths achievement. Computational fluency had the strongest effect on algebra achievement, with 3D spatial ability and working memory showing moderate effects. In contrast, 3D spatial ability had a stronger effect on SAT‐M scores than did computational fluency. Computational fluency and 3D spatial ability completely mediated the effect of working memory for both algebra and SAT‐M achievement. 相似文献

The present study examined the impact of participation rate and nine other educational and demographic variables on state mean scores for the Scholastic Aptitude Test (SAT). Participation rate, defined as the percentage of a state's high school seniors taking the SAT represented by the z-score mean of a truncated normal distribution, was the most important single predictor of state mean SAT score, accounting for 77% of the total variance in mean scores. The inclusion of significant educational and demographic variables raised the proportion of variance explained to 94%. The fallacy of comparing the mean standardized test scores of different locations or time periods without taking participation rate into account is discussed. 相似文献

Postsecondary schools have traditionally relied on admissions tests such as the SAT and ACT to select students. With high school achievement assessments in place in many states, it is important to ascertain whether scores from those exams can either supplement or supplant conventional admissions tests. In this study we examined whether the Arizona Instrument to Measure Standards (AIMS) high school tests could serve as a useful predictor of college performance. Stepwise regression analyses with a predetermined order of variable entry revealed that AIMS generally did not account for additional performance variation when added to high school grade-point average (HSGPA) and SAT. However, in a cohort of students that took the test for graduation purposes, AIMS did account for about the same proportion of variance as SAT when added to a model that included HSGPA. The predictive value of both SAT and AIMS was generally the same for Caucasian, Hispanic, and Asian American students. The ramifications of universities using high school achievement exams as predictors of college success, in addition to or in lieu of traditional measures, are discussed. 相似文献
