National data show a continuing decline in the willingness of people to respond to surveys. This trend is troubling given the central role that survey research plays in collecting data for institutional research purposes. This paper examines the effectiveness of a weighting procedure described by Astin and Molm for adjusting survey results to correct for nonresponse bias. Using data from a Cooperative Institutional Research Program (CIRP) follow-up survey, the results indicate that the weighting procedure is highly effective at reducing nonresponse bias in univariate distributions. The effectiveness of the weighting procedure in adjusting correlation and regression analyses is less clear. This may be due in part to the observation that even when individual variables are noticeably biased, their relationships with each other tend not to be.  相似文献

Assessing Response Rates and Nonresponse Bias in Web and Paper Surveys   总被引：5，自引：0，他引：5  
Using data collected as part of the second pilot administration of Your First College Year (YFCY), a national survey of first-year college students, this study was designed to examine both response rates and nonresponse bias across four survey administration groups: paper-only, paper with web option, web-only with response incentive, and web-only without response incentive. Findings indicate that response rates vary by mode of administration. Moreover, predictors of response differed by administration group. Results are discussed in light of the recent surge of interest in online survey research.  相似文献

This study uses college student survey data and corresponding administrative data on campus recreation facility usage, academic performance, physical education class attendance, and co-curricular participation to examine nonresponse bias in college student surveys. Within the context of the Groves (Public Opin Q 70:646–675, 2006) Alternative Cause Model, we found compelling evidence of the presence of nonresponse error observed as student characteristics related to the survey topic that also explain their response propensity. An individual’s survey response propensity has a statistically significant relationship with their actual behavior for 2 of 3 survey topics. In 11 of the 13 survey questions used to measure the survey topic behaviors, we found statistically significant differences between the respondent and nonrespondent behavioral measures. These findings hold important implications for survey researchers and those using student surveys for high-stakes accountability measures because survey summary statistics may not be generalizable to the target population.

Two-year colleges are an important part of the higher education system in the United States but there are concerns as to how attendance at these institutions affects educational attainment and labor market outcomes. This paper uses data from a nationally representative survey to examine the impact of students beginning their college career at a two-year college instead of a four-year college. Treatment effects are estimated using both standard regression techniques as well as propensity score matching. As these estimates may be contaminated because of selection on unobservable characteristics this paper will also employ a number of sensitivity analyses to consider the potential bias. The results show large negative impacts on both educational attainment and labor market outcomes for men and women who begin at a two-year college, even for those students who expect to complete a bachelor's degree. The evidence from the sensitivity analyses suggest that to eliminate these large effects there would need to be substantial, and arguably implausible, selection on unobservable characteristics.  相似文献

Rouse [Rouse, C. E. (1995). Democratization or diversion—the effect of community-colleges on educational-attainment. Journal of Business and Economic Statistics, 13(2), 217–224] finds that enrollment in a community college may divert students from attaining a bachelor's degree. However, this result may be due to selection bias, as the population of community college students should be quite different from those who attend 4-year institutions in terms of both observable and unobservable characteristics. This study uses propensity score matching to non-parametrically balance a data set from the 1996 Beginning Postsecondary Students survey in order to overcome issues associated with selection bias. Results from a Cox proportional hazards model indicate that attendance at a community college lowers the hazard rate for completing a bachelor's degree. The results are consistent with previous studies.  相似文献

In this article we analyze the effects of student work on academic performance for college students. In order to reduce the endogeneity bias due to selection into treatment, we use propensity score matching technique. This approach allows us to estimate the effects of student work separately for different years of study, which is not possible when inside instruments are used to deal with endogeneity of student work. We find predominantly negative effects of student work for all measures of academic performance (GPA, exam attempts, exams passed, and likelihood of passing a year), although many of these are economically and statistically insignificant. We supplement existing studies that do not estimate separate treatment effects for different years of study by showing that work while in college harms study outcomes mostly in the first year of study—by passing smaller number of exams and thereby increasing the likelihood of failing a year. Our results are consistent with evidence on difficulty with adjusting to college studies of first-year students, who face many uncertainties that affect finding the optimal allocation of time between studies, work and leisure.  相似文献

Respondent attrition is a common problem in national longitudinal panel surveys. To make full use of the data, weights are provided to account for attrition. Weight adjustments are based on sampling design information and data from the base year; information from subsequent waves is typically not utilized. Alternative methods to address bias from nonresponse are full information maximum likelihood (FIML) or multiple imputation (MI). The effects on bias of growth parameter estimates from using these methods are compared via a simulation study. The results indicate that caution needs to be taken when utilizing panel weights when there is missing data, and to consider methods like FIML and MI, which are not as susceptible to the omission of important auxiliary variables.  相似文献

Abstract

Teaching modalities and in-service training activities that show promise of increasing student learning and teaching effectiveness are identified. The subjects were 25 community/junior college instructors with an average of 5.08 yr of college teaching experience and at least a master's degree, who participated in a 6-wk institute. Modern educational technology facilities, including fully equipped microteaching labs, were used to train the participants in Flanders Interaction Analysis and questioning strategies. The Delphi process, surveys involving the Likert scale, and follow-up visits to campuses were used to collect data. The participants identified several modalities and training techniques as effective.  相似文献

The purpose of this study is to develop and evaluate unidimensional models that can handle semiordered data within scale items (i.e., items with multiple ordered response categories, and one additional nominal response category). We apply the models to scale data with not applicable (NA) responses to compare the model performance to conditions in which NA responses are treated as missing and ignored. We also conduct a small simulation study based on the operational study to evaluate the parameter recovery of the models under the operational conditions. Findings indicate that the proposed models show promise for (a) reducing standard errors of trait estimates for persons who select NA responses, (b) reducing nonresponse bias in trait estimates for persons who select NA responses, and (c) providing substantive information to practitioners about the nature of the relationship between NA selection and the trait of measurement.  相似文献

Competence data from low‐stakes educational large‐scale assessment studies allow for evaluating relationships between competencies and other variables. The impact of item‐level nonresponse has not been investigated with regard to statistics that determine the size of these relationships (e.g., correlations, regression coefficients). Classical approaches such as ignoring missing values or treating them as incorrect are currently applied in many large‐scale studies, while recent model‐based approaches that can account for nonignorable nonresponse have been developed. Estimates of item and person parameters have been demonstrated to be biased for classical approaches when missing data are missing not at random (MNAR). In our study, we focus on parameter estimates of the structural model (i.e., the true regression coefficient when regressing competence on an explanatory variable), simulating data according to various missing data mechanisms. We found that model‐based approaches and ignoring missing values performed well in retrieving regression coefficients even when we induced missing data that were MNAR. Treating missing values as incorrect responses can lead to substantial bias. We demonstrate the validity of our approach empirically and discuss the relevance of our results.  相似文献

BIAS IN SELECTION   总被引：1，自引：0，他引：1  
Possible bias in selection procedures used for employment and college admissions is of crucial social and educational importance. However, there are many different definitions of what constitutes bias with each definition based on different values and with different implications for how selection should be accomplished. A number of these definitions of bias and their implications are examined, and a new conditional probability model of fairness based on equal opportunity for potentially successful applicants is presented. This conditional probability model is proposed as an intuitively appealing and socially desirable model for use in many selection situations in employment and college admissions.  相似文献

This study was designed to examine response rates and bias among a sample of community college students who received a district-wide survey by standard mail or e-mail. Findings suggest that predictors of response and types of responses are not appreciably different across paper and online mail-out samples when these samples are “matched” in terms of key demographics. Rates of response, however, differ by mode of survey administration, gender, and race/ethnicity.  相似文献

Although textbooks on educational research give only scant attention to survey research methodology, its extensive use in education provides a strong rationale for improving the preparation of educational researchers in effectively applying survey methods. This study reviews methods for dealing with nonresponse bias, the primary problem presented by survey methods. It also provides an updated review of the literature of studies investigating the effectiveness of incentives to increase survey response rates. We hypothesized that a reanalysis of reviewed studies, using a linear trend test, would resolve the inconsistencies found regarding the effectiveness of incentives to increase response rates. The results of the reanalysis and guidelines for educational researchers in systematically selecting and applying incentives to increase response rates are discussed.  相似文献

In order to explore the development of self-evaluative biases, children at 3 age levels (5–6, 7–8, 9–10) evaluated themselves or another child when given social or temporal comparison feedback. Evaluative biases were indicated by higher evaluations for the self than another, especially after failure. Children at different ages were not differentially responsive to temporal vs. social comparison information. However, evaluative bias in response to the type of evaluation differed by age; there was greater bias for general ability evaluations by older children and greater bias for specific performance evaluations by younger children. Alternative explanations for these self-other differences were minimized, as differences in visual orientation were held constant and differences in knowledge of effort were controlled statistically. Other aspects of the design as well as sex differences support a motivational interpretation of these biases. How these biases are manifested is related to children's level of understanding and concerns at different ages.  相似文献

This paper compares the social origins of 400 nursing students in hospital‐based and 448 nursing students in college‐based programs in New South Wales. Using a specially constructed composite socioeconomic variable for comparison, the preliminary analysis suggests that a middle class bias, presumed to exist by some in the selection of recruits to hospital‐based programs, does not operate in the selection of college recruits. The soundly equitable college recruitment pattern is more marked for females than males. There is a greater proportion recruited to college programs from the group who have delayed entry for more than ten years after leaving school. For students entering directly from school, no significant difference was found in the composite socioeconomic variable in hospital and college programs. The findings also suggest that college programs are more attractive than hospital programs to males entering directly from school.  相似文献

An exploratory study was conducted to compare the effectiveness of two different career education courses on career decision making for college freshmen in Taiwan. Two different career education courses were designed for college students; one was a cognitive restructuring intervention and the other was a career decision skills training intervention. The cognitive restructuring career education course was compared to two other conditions. Approximately 164 college freshmen were administered the Career Decision Scale, a demographic sheet, and a follow-up questionnaire. The design selected for the study was a pre- and post-test design, using two experimental groups (two approaches to career education courses) and one control group. A total of 152 subjects completed both pre- and post-analyses. A 3 × 2 multivariate analysis of covariance (MANCOVA) was performed. The factors were treatment and gender. In the comparisons of the students who took the two different approaches to career education courses and the students who did not, statistical analyses of the data indicated that regardless of gender, a significant treatment main effect on the indecision scale of the Career Decision Scale was found. However, there were no significant treatment group differences between the two experimental groups. Implications and suggestions for designing a college career education course were also discussed.  相似文献

This study uses fixed-effects panel data techniques to estimate the elasticity of community college enrollment demand relative to local unemployment rates. The findings suggest that community college enrollment demand is counter-cyclical to changes in the labor market, as enrollments rise during periods of weak economic conditions. Using national data for the years 1990 through 2009, we find that a one percentage-point change in unemployment is associated with 1.1–3.3 % increases in enrollment demand. We disaggregate the analysis by total full-time and part-time enrollment, concluding that high levels of unemployment are also associated with greater demand for full-time attendance. Additionally, enrollments are slightly more responsive to unemployment in metropolitan (rather than micropolitan) areas. Informed by enrollment demand theory, our analysis provides an update to the “unemployment elasticity” literature and could aid in current enrollment planning, economic development, and public policy efforts to educate students on the margin between college and work.  相似文献

Sample attrition increases the risk of statistical bias and hinders the ability to plausibly estimate causal effects when patterns of nonresponse are correlated with key variables of interest. Drawing on leverage-salience theory and other work in the behavioral psychology field, we empirically capture the impact of distinct motivational appeals on the survey response rates of elementary education teachers in a large urban school district in the northeastern United States. During spring 2017, teachers were randomized to receive one of six motivational appeals and were rerandomized to receive a different appeal each subsequent week, conditional on not having completed the survey. We observe the results on four different margins that range in their time intensity (open email and click, start, and complete survey). We find that extrinsic rewards improved teacher response across all four margins, and the social norm of reciprocity substantially improved teacher response along margins of lower time intensity. As researchers continue to conduct multitreatment arm studies and large-scale evaluations that can suffer from serious issues of sample attrition, this work highlights the contribution of message framing in survey response.  相似文献
