To examine differences in attitudes toward the medical school learning environment among student subgroups based on gender and race-ethnicity, to identify the most influential predictors of student satisfaction with the learning environment, and to create a model of student satisfaction with the learning environment.
Three years of survey data (1992-93 to 1994-95) from first-year students at the University of Michigan Medical School were combined. The total sample consisted of 430 respondents, broken into two sets of subgroups: women (n = 171) and men (n = 259), and whites (n = 239) and underrepresented minorities (n = 74). Asian students were removed from analyses when comparisons were made by race-ethnicity, but were included in the analyses for all students and those comparing men and women. Student's t-tests were used to identify differences between gender and racial-ethnic groups in mean responses to seven survey items, and effect sizes were used to characterize the magnitudes and practical significances of the differences. Forward stepwise regression was conducted to determine the best predictive models for each student subgroup and for the total sample; the subgroup models were compared with each other as well as with the total-sample model.
Cross-validation of the gender and race-ethnicity models showed that the men's satisfaction and the women's satisfaction were predicted equally well using either subgroup's model, and that the white students' satisfaction and the underrepresented-minority students' satisfaction were predicted equally well using either subgroup's model. Furthermore, the total-sample model, employing a subset of five predictors, was similar in its predictive power to the subgroup models.
The study's findings suggest that curriculum structure (timely feedback and the promotion of critical thinking) and students' perceptions of the priority faculty place on students' education are prominent predictors of student satisfaction (across all subgroups) with the learning environment. In contrast, students' perceptions of the learning environment as a comfortable place for all gender and racial-ethnic groups, although less prominent predictors of satisfaction, will discriminate among the subgroups.
基于性别和种族划分,研究学生亚组对医学院学习环境态度的差异,确定学生对学习环境满意度的最具影响力的预测因素,并构建学生对学习环境满意度的模型。
整合了密歇根大学医学院一年级学生三年(1992 - 93年至1994 - 95年)的调查数据。总样本包括430名受访者,分为两组亚组:女性(n = 171)和男性(n = 259),以及白人(n = 239)和代表性不足的少数族裔(n = 74)。在按种族划分进行比较时,亚洲学生被排除在分析之外,但在所有学生以及比较男性和女性的分析中都包含在内。使用学生t检验来确定性别和种族亚组在对七个调查项目的平均回答上的差异,并使用效应量来描述差异的大小和实际意义。进行向前逐步回归以确定每个学生亚组和总样本的最佳预测模型;将亚组模型相互比较以及与总样本模型进行比较。
性别和种族模型的交叉验证表明,使用任何一个亚组的模型对男性满意度和女性满意度的预测效果都一样好,并且使用任何一个亚组的模型对白人学生满意度和代表性不足的少数族裔学生满意度的预测效果也都一样好。此外,采用五个预测因素子集的总样本模型在预测能力上与亚组模型相似。
该研究结果表明,课程结构(及时反馈和批判性思维的培养)以及学生对教师对学生教育重视程度的看法是学生(所有亚组)对学习环境满意度的突出预测因素。相比之下,学生对学习环境是所有性别和种族群体舒适场所的看法,虽然是满意度的不太突出的预测因素,但会在亚组之间产生差异。
