Undergraduate students studying Science, Technology, Engineering and Mathematics (STEM) often fail to persist in critical "gateway" courses, resulting in students leaving the STEM pathway. Community college students leave STEM pathways at higher rates than students at universities. Implementation of a program designed to engage community college STEM students and faculty in a community of support was associated with increased persistence in STEM gateway courses and associate degree completion. Program elements included support staff, a STEM study room with peer tutors, faculty advisors, and transfer assistance. Over seven years, 415 students joined this opt-in support program. The majority of students in this program were economically disadvantaged and many were nontraditional college students. Using institutional data we tested the hypothesis that participation in this program was associated with increased student success and persistence in STEM courses and at the college. The mean GPA for students in the program in the ten courses with the highest STEM enrollments was higher (2.89) than that for other students (2.76). Quarter-to-quarter persistence was 87% for program students compared to 67% for non-program students in a matched student population. In STEM gateway courses, program students had between 1.2x to 3.5x greater likelihood than non-program students of progressing to precalculus-2 controlling for first-attempt GPA in precalculus-1. Similar persistence patterns were observed for other gateway STEM courses. Observed persistence for students in the program was higher than comparable groups of students, including persistence for those who experienced early failure in STEM courses. These data suggest students should be supported through early failure to enable persistence in critical STEM sequences, especially in gateway Math and Chemistry courses.
攻读科学、技术、工程和数学(STEM)专业的本科生经常无法坚持学习关键的“入门”课程,从而导致学生离开 STEM 学习路径。社区大学的 STEM 学生离开 STEM 学习路径的比例高于大学学生。实施一项旨在让社区大学 STEM 学生和教师参与支持社区的计划与增加 STEM 入门课程和副学士学位完成率有关。该计划的内容包括支持人员、配备有朋辈导师的 STEM 学习室、教师顾问和转学分协助。在七年多的时间里,有 415 名学生加入了这个选修支持计划。该计划中的大多数学生经济困难,许多人是非传统的大学生。我们利用机构数据检验了一个假设,即参与该计划与学生在 STEM 课程和大学中的成功和坚持率提高有关。该计划中在 STEM 注册人数最多的十门课程中的学生平均绩点(2.89)高于其他学生(2.76)。在与匹配学生群体中,参加该计划的学生的季度到季度的坚持率为 87%,而非参加该计划的学生为 67%。在 STEM 入门课程中,与非参加该计划的学生相比,参加该计划的学生在微积分 2 之前的课程中取得进步的可能性高出 1.2 到 3.5 倍,控制了微积分 1 中的首次尝试 GPA。在其他 STEM 入门课程中也观察到了类似的坚持模式。参加该计划的学生的观察到的坚持率高于可比的学生群体,包括那些在 STEM 课程中早期失败的学生的坚持率。这些数据表明,应该通过早期失败来支持学生,以使他们能够在关键的 STEM 序列中坚持下去,特别是在入门数学和化学课程中。
