Title: How students taking introductory biology experience the chemistry content
Student experiences learning chemistry have been well studied in chemistry courses but less so in biology courses. Chemistry concepts are foundational to introductory biology courses, and student experiences learning chemistry concepts may impact their overall course experiences and subsequent student outcomes. In this study, we asked undergraduate students enrolled in introductory biology courses at a public R1 institution an open-response question asking how their experiences learning chemistry topics affected their identities as biologists. We used thematic analysis to identify common ideas in their responses. We found that while almost half of student respondents cited learning chemistry as having positive impacts on their experiences learning biology, students who struggled with chemistry topics were significantly more likely to have negative experiences learning biology. We also found significant relationships between prior chemistry preparation, student background, and the likelihood of students struggling with chemistry and negative experiences learning biology. These findings emphasize the impact of learning specific content on student psychosocial metrics and suggest areas for biology educators to focus on to support learning and alleviate student stress in introductory biology.  more » « less

    Introductory courses are often designed to cover a range of topics with the intent to offer students exposure to the given discipline as preparation to further their study in the same or related disciplines. Unfortunately, students in these courses are often presented with an overwhelming amount of information that may not support their formation of a usable coherent network of knowledge. In this study we conducted a mixed-method sequential exploratory study with students co-enrolled in General Chemistry II and Introductory Biology I to better understand what students perceived to be the “take-home” messages of these courses (i.e., core ideas) and the connections between these courses. We found that students identified a range of ideas from both courses; further analysis of students’ explanations and reasoning revealed that, when students talked about their chemistry ideas, they were more likely to talk about them as having predictive and explanatory power in comparison with reasons provided for their biology big ideas. Furthermore, students identified a number of overlapping ideas between their chemistry and biology courses, such as interactions, reactions, and structures, which have the potential to be used as a starting place to support students building a more coherent network of knowledge.

  2. It is no secret that the retention of students majoring in Science, Technology, Engineering, and Mathematics (STEM) has presented itself to be a challenge across the country. The National Science Foundation (NSF) allots substantial funding annually towards this effort. Jackson State University’s (JSU) Students Understanding Chemistry Concepts to Enhance STEM Skills (SUCCESS) Program is one such effort funded by the NSF. While the JSU Department of Biology had over 900 majors in 2016, data suggested that less than 23% would graduate with a bachelor’s degree within six years of entry. According to data obtained, the first four chemistry courses, General Chemistry (I & II) and Organic Chemistry (I & II), were significant barriers to the educational success of many Biology majors. A review of the literature provides many examples of initiatives to improve student retention. A reoccurring theme found that the comprehensive understanding of the students’ experiences within a particular major is essential to determining how best to impact student retention in that department. Student focus groups were implemented to evaluate the perceptions of Biology majors enrolled in Chemistry classes who utilized the SUCCESS Program. The overall impression of students in the SUCCESS Program was that it was helpful and beneficial to their classroom success, increased their confidence to learn Chemistry, and improved their understanding of Chemistry concepts. The students often identified scheduling conflicts as a hindrance to their participation. They also felt that the program was needed to help most students pass their tests.

    ABSTRACT Evolution is one of the most important concepts in biology, but it is rejected by a substantial percentage of religious students due to a perceived conflict with their religious beliefs. The use of religious cultural competence in evolution education (ReCCEE) has been shown to effectively increase evolution acceptance among religious students during in-person instruction, but there is no research that we know of that indicates the effectiveness of these practices during online instruction. In this study, we explored the efficacy of online culturally competent practices for religious students on students’ evolution understanding, evolution acceptance, and comfort learning evolution at a religious university. Before and after evolution instruction, we surveyed 178 students in online introductory biology courses and compared these student outcomes to 201 students in the same instructor’s in-person introductory biology courses. We found that evolution acceptance and understanding increased in online classes with culturally competent practices, and these gains were similar to those observed in the in-person courses. Despite these similarities, we found that students were more comfortable learning evolution in person than online, but this difference was small. Our findings suggest that the use of culturally competent practices online can be as effective as their use for in-person instruction for improving students' attitudes toward evolution, but in-person instruction may be more effective for cultivating students’ comfort while learning evolution.

  4. Abstract Introductory STEM courses represent entry points into a major, and student experiences in these courses can affect both their persistence and success in STEM disciplines. Identifying course-based student concerns may help instructors detect negative perceptions, areas of struggle, and potential barriers to success. Using an open-response survey question, we identified 13 common concerns expressed by students in introductory STEM courses. We converted these student-generated concerns into closed-ended items that were administered at the beginning and middle of the semester to students in 22 introductory STEM course sections across three different institutions. Students were asked to reflect on each item on a scale from very concerned to not concerned. A subset of these concerns was used to create a summary score of course-based concern for each student. Overall levels of student concern decreased from the first week to the middle of the semester; however, this pattern varied across different demographic groups. In particular, when controlling for initial concern and course grades, female students held higher levels of concern than their peers. Since student perceptions can impact their experiences, addressing concerns through communication and instructional practices may improve students’ overall experiences and facilitate their success.

    Synopsis  Early exposure to course-based undergraduate research experiences (CUREs) in introductory biology courses can promote positive student outcomes such as increased confidence, critical thinking, and views of applicability in lower-level courses, but it is unknown if these same impacts are achieved by upper-level courses. Upper-level courses differ from introductory courses in several ways, and one difference that could impact these positive student outcomes is the importance of balancing structure with independence in upper-level CUREs where students typically have more autonomy and greater complexity in their research projects. Here we compare and discuss two formats of upper-level biology CUREs (Guided and Autonomous) that vary along a continuum between structure and independence. We share our experiences teaching an upper-level CURE in two different formats and contrast those formats through student reported perceptions of confidence, professional applicability, and CURE format. Results indicate that the Guided Format (i.e., a more even balance between structure and independence) led to more positive impacts on student outcomes than the Autonomous Format (less structure and increased independence). We review the benefits and drawbacks of each approach while considering the unique elements of upper-level courses relative to lower-level courses. We conclude with a discussion of how implementing structured skill-building can assist instructors in adapting CUREs to their courses.
