Consistent occupational preferences and academic adjustment     

W. Bruce Walsh  Arnold R. Spokane  Elizabeth Mitchell 《Research in higher education》1976,4(2):123-129

This study explored the differences in academic adjustment variables between students who made congruent, incongruent, and undecided college major choices. The academic adjustment variables were operationally defined by the College Inventory of Academic Adjustment. Congruent, incongruent, and undecided college major choice groups were defined operationally using the Vocational Preference Inventory. The analysis of variance revealed the main effect of groups (congruent, incongruent, and undecided) to be significant for two academic adjustment variables. The test for the main effect of sex was found to be significant for one adjustment variable. The test for interaction was found to be significant for one variable. The findings suggest that students in the congruent female and male groups tend to be more academically adjusted than students in the undecided male group.  相似文献   

零值劳动学说与我国农村人力资源开发     

宋玲妹 《许昌学院学报》2007,26(4):114-116

我国农村人力资源基数大,增长速度快,但整体素质偏低,造成了农村人力资源乡城流动与就业困难,劳动力剩余严重,劳动效率低下。刘易斯的零值劳动学说以乐观的态度看待发展中国家农村剩余劳动力乡城流动,从而实现工农业齐头并进的前景,对研究我国农村人力资源的开发问题具有一定的借鉴和启发意义。但我国农村剩余劳动力就业的出路不单是乡城流动,而必须在充分开发农村人力资源的基础上,在农村人力资本积累和形成的过程中,实现农村剩余劳动力的多产业、多领域、多渠道转移。  相似文献

A Mixture IRTree Model for Extreme Response Style: Accounting for Response Process Uncertainty     

Nana Kim  Daniel M. Bolt 《Educational and psychological measurement》2021,81(1):131

This paper presents a mixture item response tree (IRTree) model for extreme response style. Unlike traditional applications of single IRTree models, a mixture approach provides a way of representing the mixture of respondents following different underlying response processes (between individuals), as well as the uncertainty present at the individual level (within an individual). Simulation analyses reveal the potential of the mixture approach in identifying subgroups of respondents exhibiting response behavior reflective of different underlying response processes. Application to real data from the Students Like Learning Mathematics (SLM) scale of Trends in International Mathematics and Science Study (TIMSS) 2015 demonstrates the superior comparative fit of the mixture representation, as well as the consequences of applying the mixture on the estimation of content and response style traits. We argue that methodology applied to investigate response styles should attend to the inherent uncertainty of response style influence due to the likely influence of both response styles and the content trait on the selection of extreme response categories.  相似文献   

Latent Variable Modeling and Adaptive Testing for Experimental Cognitive Psychopathology Research     

Michael L. Thomas  Gregory G. Brown  Virginie M. Patt  John R. Duffy 《Educational and psychological measurement》2021,81(1):155

The adaptation of experimental cognitive tasks into measures that can be used to quantify neurocognitive outcomes in translational studies and clinical trials has become a key component of the strategy to address psychiatric and neurological disorders. Unfortunately, while most experimental cognitive tests have strong theoretical bases, they can have poor psychometric properties, leaving them vulnerable to measurement challenges that undermine their use in applied settings. Item response theory–based computerized adaptive testing has been proposed as a solution but has been limited in experimental and translational research due to its large sample requirements. We present a generalized latent variable model that, when combined with strong parametric assumptions based on mathematical cognitive models, permits the use of adaptive testing without large samples or the need to precalibrate item parameters. The approach is demonstrated using data from a common measure of working memory—the N-back task—collected across a diverse sample of participants. After evaluating dimensionality and model fit, we conducted a simulation study to compare adaptive versus nonadaptive testing. Computerized adaptive testing either made the task 36% more efficient or score estimates 23% more precise, when compared to nonadaptive testing. This proof-of-concept study demonstrates that latent variable modeling and adaptive testing can be used in experimental cognitive testing even with relatively small samples. Adaptive testing has the potential to improve the impact and replicability of findings from translational studies and clinical trials that use experimental cognitive tasks as outcome measures.  相似文献   

Parameter Estimation Accuracy of the Effort-Moderated Item Response Theory Model Under Multiple Assumption Violations     

Joseph A. Rios  James Soland 《Educational and psychological measurement》2021,81(3):569

As low-stakes testing contexts increase, low test-taking effort may serve as a serious validity threat. One common solution to this problem is to identify noneffortful responses and treat them as missing during parameter estimation via the effort-moderated item response theory (EM-IRT) model. Although this model has been shown to outperform traditional IRT models (e.g., two-parameter logistic [2PL]) in parameter estimation under simulated conditions, prior research has failed to examine its performance under violations to the model’s assumptions. Therefore, the objective of this simulation study was to examine item and mean ability parameter recovery when violating the assumptions that noneffortful responding occurs randomly (Assumption 1) and is unrelated to the underlying ability of examinees (Assumption 2). Results demonstrated that, across conditions, the EM-IRT model provided robust item parameter estimates to violations of Assumption 1. However, bias values greater than 0.20 SDs were observed for the EM-IRT model when violating Assumption 2; nonetheless, these values were still lower than the 2PL model. In terms of mean ability estimates, model results indicated equal performance between the EM-IRT and 2PL models across conditions. Across both models, mean ability estimates were found to be biased by more than 0.25 SDs when violating Assumption 2. However, our accompanying empirical study suggested that this biasing occurred under extreme conditions that may not be present in some operational settings. Overall, these results suggest that the EM-IRT model provides superior item and equal mean ability parameter estimates in the presence of model violations under realistic conditions when compared with the 2PL model.  相似文献

Expectancy-value profiles in math and science: A person-centered approach to cross-domain motivation with academic and STEM-related outcomes     

《Contemporary educational psychology》2021

The need to enhance the STEM workforce and, in turn, the STEM educational pipeline is a prevailing issue in the U.S. One critical component in this pipeline is students’ interest in STEM majors and their persistence in such majors, theorized to be a function of both students’ perceived value and expectancy beliefs in the subject matter. Using an expectancy-value lens, we examined cross-domain patterns of high school students’ expectancy beliefs and values in both mathematics and science using a person-centered or profile approach. With data from the High School Longitudinal Study, latent profile analysis revealed five profiles characterized as Low Math/Low Science (i.e., endorsing low levels of expectancy and value beliefs in math and science), Moderate Math/Moderate Science, High Math/High Science, Low Math/High Science, and High Math/Low Science. Taking into account aspects of students’ background and school context, we found that motivational profile membership predicted math and science high school achievement, college persistence, and both STEM major intentions and major choices. Moreover, there were a number of gender and racial/ethnic differences and contextual variation in profile memberships as well. Implications for theory and educational practice are discussed in relation to study findings.  相似文献   

教师参与学校治理意愿影响因素的实证研究--计划行为理论框架下的分析     

魏叶美  范国睿 《华东师范大学学报(教育科学版)》2021,(4):73-82

促进包括教师在内的多元主体参与是学校治理现代化的必然要求。本研究基于上海市442名中学教师的问卷调查,在计划行为理论框架下,对影响教师参与学校治理意愿的机制进行了实证分析。结果发现:(1)主观规范、知觉行为控制、参与治理态度和教师参与学校治理意愿显著正相关;(2)主观规范、知觉行为控制不仅可以直接正向预测教师参与学校治理意愿,还可以通过参与治理态度间接作用于教师参与学校治理意愿;(3)教师身份和教龄对主观规范通过参与治理态度影响教师参与治理意愿的中介效应有调节作用,非教代会代表、新手教师的效应更明显。需要加强参与理念宣传,营造良好参与氛围;注重意见反馈,提高教师参与效能感;用好激励机制,转变教师参与治理的态度;拓展参与范围,尤其注重新教师和非教代会代表在学校治理中的参与。  相似文献
