乔治亚·格温尼特学院(GGC)是一所拥有多元化学生群体的接入机构，位于亚特兰大大都会区。为了加强研究技能，教授雇主重视的细胞生物学实验室技术，并增加学生的参与度，在实验室细胞生物学(BIOL3400K)中开发并实施了一项为期一学期的探究式治疗，这是一门大二水平的课程，是进入所有高级生物学课程的“门户”。这一疗法的核心是研究学生选择的关于培养的哺乳动物细胞活力的实验因素。通过参与这项治疗，学生们获得了细胞培养、荧光显微镜和活性分析方面的经验，并加强了重要的研究技能，如文献搜索、图表绘制和数据分析。通过内容前后考试和科罗拉多州科学学习态度调查(CLASS)评估了这种疗法对学生学习收益和态度的影响。我们的数据显示，所有学生都取得了显著的内容增长。女学生比男学生获得了更大的学习收益。此外，少数族裔学生在某些内容领域的表现好于多数族裔学生。学生的态度没有改变，或者在某些情况下，在治愈后略有变得更加消极。总体而言，这种疗法通过让学生参与基于探究的实验室体验，对他们产生了积极的影响。
Georgia Gwinnett College (GGC) is an access institution with a diverse student body, located in metro Atlanta. To strengthen research skills, teach employer-valued cell biology laboratory techniques, and increase student engagement, a semester-long, inquiry-based CURE was developed and implemented in Cell Biology with Laboratory (BIOL3400K), a sophomore-level course, which serves as a "gateway" to all upper-level biology courses. This CURE centers on the investigation of a student-chosen experimental factor on the viability of cultured, mammalian cells. Through participation in this CURE, students gain experience in cell culture, fluorescence microscopy, and viability assays, and strengthen important research skills, such as literature searches, graphing, and data analyses. The impact of this CURE on student learning gains and attitudes was assessed using pre-/post-content exams and the Colorado Learning Attitudes about Science Survey (CLASS). Our data show that all students made significant content gains. Female students made larger learning gains than male students. Additionally, minority students performed better than majority students in some content areas. Student attitudes did not change, or in some cases were slightly more negative after the CURE. Overall, this CURE had a positive impact on students by engaging them in an inquiry-based laboratory experience.
