Motivation and Self-regulation in Community College Transfer Students at a Four-year Online University

ABSTRACT

Motivation and self-regulation were examined in a sample of community college transfer students enrolled in a 4-year, online university. The relation between motivation and self-regulation and students’ performance was examined, as was the association between these learner characteristics (i.e., motivation and self-regulation) and sociodemographic factors (e.g., marital status, employment status). Motivation was found to be significantly correlated with both semester and cumulative grade point average (GPA), while associations between self-regulation and performance were more limited. Further, motivation was found to be a significant predictor of semester GPA in a model controlling for sociodemographic factors and prior achievement. Motivation and self-regulation were also found to differ according to students’ sociodemographic status. For instance, transfer students with children under 18 were found to have significantly higher levels of motivation than nonparents. Those employed full-time had lower levels of self-regulation than did their nonemployed peers. Implications for further research on community college transfer students and online learning are discussed.     

Improving Factor Score Estimation Through the Use of Observed Background Characteristics

A challenge facing nearly all studies in the psychological sciences is how to best combine multiple items into a valid and reliable score to be used in subsequent modeling. The most ubiquitous method is to compute a mean of items, but more contemporary approaches use various forms of latent score estimation. Regardless of approach, outside of large-scale testing applications, scoring models rarely include background characteristics to improve score quality. This article used a Monte Carlo simulation design to study score quality for different psychometric models that did and did not include covariates across levels of sample size, number of items, and degree of measurement invariance. The inclusion of covariates improved score quality for nearly all design factors, and in no case did the covariates degrade score quality relative to not considering the influences at all. Results suggest that the inclusion of observed covariates can improve factor score estimation.     

Improving the Acquisition of Novel Vocabulary Through the Use of Imagery Interventions

The purpose of this study was to investigate the impact of imagery interventions on the vocabulary acquisition abilities of second grade students. A total of 15 students were randomly assigned to three different intervention conditions: Word Only, which involves the simple verbal presentation of a vocabulary word; Dual Coding, in which a picture was paired with the vocabulary word, and Image Creation, in which students were told to create a mental picture of the vocabulary word in their mind and draw it on paper. These students were taught a total of 21 vocabulary words: seven animal and habitat words, seven musical instrument terms, and seven science terms. A Latin square design was used, in which each group of students rotated through each of the interventions, being exposed to a different treatment condition for each category of words. Participants were measured on the number of words they were successfully able to acquire through the use of experimenter designed comprehension measures. While no statistical significance was shown between the interventions across the word categories, a significant difference was found between the Image Creation and Word Only interventions within the science terms category. Students also reported that the imagery interventions facilitated the ease with which they learned the words. The findings have implications for increasing the success of classroom instruction, specifically for presenting novel vocabulary words to early elementary learners using imagery methods.     

Improving the Efficiency and Effectiveness of Grading Through the Use of Computer-Assisted Grading Rubrics

This study tests the use of computer‐assisted grading rubrics compared to other grading methods with respect to the efficiency and effectiveness of different grading processes for subjective assignments. The test was performed on a large Introduction to Business course. The students in this course were randomly assigned to four treatment groups based on the grading method. Efficiency was measured by the professor's time to grade the assignments; effectiveness was measured by a student satisfaction survey. Results suggest that the computer‐assisted grading rubrics were almost 200% faster than traditional hand grading without rubrics, more than 300% faster than hand grading with rubrics, and nearly 350% faster than typing the feedback into a Learning Content Management System. Results also seemed to indicate that the use of a computer‐assisted grading rubric did not negatively affect student attitudes concerning the helpfulness of their feedback, their satisfaction with the speed with which they received their feedback, or their satisfaction with the method by which they received feedback.

现代信息技术与大学课堂思维训练问题

课堂教学是在一定的时间和有限的空间中开展的。现代信息技术进入课堂,拓展了课堂教学的空间,为课堂教学方式的改进提供了条件,为大学生的课堂思维训练提供了更多的可能。教师的教学设计是能否实现这些可能性的关键。教学设计只有在教学内容的选择与组织过程中,注意到了学生的思维训练问题,并且制作成既能反映教学意图又兼顾学生感受的课件,才能在课堂上使现代信息技术在发展大学生思维能力上发挥积极作用。     

动机的激发：家庭第一代大学生在线自我调节学习的潜在机制研究

基于疫情期间上海39所本科院校在校生线上提供的64949份有效问卷，本研究设计了《本科生在线自我调节学习量表》并进行信效度检验。回归统计结果表明：家庭第一代大学生在线自我调节学习的自评得分均值显著低于非家庭第一代大学生，在控制学习动机与就业焦虑这两个潜在影响机制之后，这种差距明显缩小乃至不再显著；学习动机的解释力度最大，尤其是“努力解决学习中的问题”与“喜欢阅读与专业相关的书籍”这两项与内在动机相关的行为表征；就业焦虑对本科生在线自我调节学习有显著的负面效应；加入交互项之后的回归结果支持学习动机这一潜在变量的调节作用，进而揭示未来对家庭第一代大学生在线学习的有效干预可侧重于内在动机的激发。     

Faculty Motivation to Mentor Students Through Undergraduate Research Programs: A Study of Enabling and Constraining Factors

Undergraduate research experiences are a “high impact” educational practice that confer benefits to students. However, little attention has been paid to understanding faculty motivation to mentor undergraduate students through research training programs, even as the number of programs has grown, requiring increasing numbers of faculty mentors. To address this, we introduce a conceptual model for understanding faculty motivation to mentor and test it by using empirical data to identify factors that enable and constrain faculty engagement in an undergraduate research program. Using cross-sectional survey data collected in 2013, we employed generalized linear modeling to analyze data from 536 faculty across 13 research institutions to examine how expected costs/benefits, dispositional factors, situational factors, previous experience, and demographic factors predicted faculty motivation to mentor. Results show that faculty who placed greater value on the opportunity to increase diversity in the academy through mentorship of underrepresented minorities were more likely to be interested in serving as mentors. Faculty who agreed more strongly that mentoring undergraduate students was time consuming and their institution’s reward structures were at odds with mentoring, or who had more constrained access to undergraduate students were less likely to be interested in serving as mentors. Mid-career faculty were more likely than late-career faculty to be interested in serving as mentors. Findings have implications for improving undergraduate research experiences, since the success of training programs hinges on engaging highly motivated faculty members as mentors.
