Supporting Undergraduate Biology Students’ Academic Success: Comparing Two Workshop Interventions

When teaching college biology students to use effective learning strategies, does it help to address both the what and the when of studying? Findings indicated that students who learned about time management in addition to metacognition had higher exam grades and commitment to earning a college degree at the end of the semester.

A New Measure of Students’ Perceived Conflict between Evolution and Religion (PCoRE) Is a Stronger Predictor of Evolution Acceptance than Understanding or Religiosity

College biology students’ perceived conflict with their religions was found to be the strongest predictor of evolution acceptance compared with student religiosity, religious affiliation, and understanding of evolution. A new instrument to measure perceived conflict between religion and evolution (PCoRE) is provided for researchers.

Implementation of a Flipped Active-Learning Approach in a Community College General Biology Course Improves Student Performance in Subsequent Biology Courses and Increases Graduation Rate

A large-scale study on the efficacy of active learning in a community college biology class showed that students in active-learning sections earned higher exam scores, performed better in subsequent biology courses, and graduated at a higher rate compared with students from traditional sections.

It’s in the syllabus … or is it? How biology syllabi can serve as communication tools for creating inclusive classrooms at a large-enrollment research institution

Syllabi are usually required by institutions of higher education and often are the first exposure that students have to a particular course. Instructors can use syllabi as a mechanism to convey important information to students. Moreover, a syllabus can be considered a tool to create inclusive biology courses by transmitting information to all students equitably. In this study, we examined 75 biology course syllabi collected from a research-intensive institution to examine what content instructors include. We reviewed the syllabi to determine the presence or absence of elements and assessed to what extent there were differences in the presence or absence of certain syllabus elements based on course level and course size. We found that instructors are most likely to include content about course expectations and least likely to include content about creating positive classroom climate on their course syllabi. Despite university requirements, many instructors did not include the university-mandated criteria and they did not include elements that could increase how inclusive students perceive the course to be. However, instructors more often included inclusive content when it was required by the university. We also found that students enrolled in upper level courses and small enrollment courses are provided with less content on their syllabi, which we would then interpret as a less inclusive syllabus. We discuss the implications of how these results may differentially impact students in these courses and how the syllabus can be a tool for creating more inclusive college biology courses.

Using Crayfish Burrows to Illustrate Simple Ecological Field Techniques

Ecological field techniques such as transect surveys are long-used, integral means of immersing students in field exercises to illustrate ecological measures. Many species of crayfish create conspicuous burrows within or near aquatic habitats. Such burrows can easily be identified and measured by students during an ecological field exercise. In this article, we describe a field activity we developed as part of a college-level course in which students utilized transects and calipers to collect counts and measurements of crayfish burrows in order to evaluate their distribution and size among different substratum types along a small stream. This field exercise could be incorporated, with or without modification, into an applicable high school or introductory/intermediate college biology course as a means of illustrating ecological concepts, sampling technique, and/or behavioral biology.

BioSkills Guide: Development and National Validation of a Tool for Interpreting the Vision and Change Core Competencies

This article presents the BioSkills Guide, a resource enumerating program- and course-level learning outcomes aligned with the six core competencies of Vision and Change. The learning outcomes were developed and then nationally validated using input from more than 600 college biology educators from a range of biology fields and institution types.

Using Poetry in the Undergraduate Biology Classroom

Traditional assessments in college biology classrooms, such as exams and lab reports, often have limited utility in promoting long-lasting understanding of course material and do not always engage students from all backgrounds. The inclusion of creative scientific writing assignments, especially those that require application of sophisticated course material, is an underutilized strategy in higher education. Here, we describe our use of student-generated poetry in two midlevel undergraduate biology classes. We have found that by encouraging students to write poems in response to carefully crafted prompts and having them assess the scientific accuracy of the poems, we can encourage them to identify misconceptions prior to exams, potentially resulting in deeper and longer-lasting understanding of course material. Furthermore, the inclusion of poetry empowers students who might not otherwise participate in class to contribute, resulting in a more inclusive classroom climate.

Diagram comprehension ability of college students in an introductory biology course

College biology courses commonly use diagrams to convey information. These visual representations are embedded in course materials with the expectation that students can comprehend and learn from them. Educational research, however, suggests that many students have difficulty understanding diagrams and the conventions (e.g., labels, arrows) they contain. The present study evaluates biology students’ ability to comprehend scientific diagrams and the diagram characteristics that affect this comprehension. Participants were students in a physiology course who completed a multiple-choice test of diagram comprehension ability (DCA) (Cromley JG, Perez TC, Fitzhugh SL, Newcombe NS, Wills TW, Tanaka JC. J Exp Educ 81: 511–537, 2013). We coded the conventions used in each test diagram and used these codes to capture the diagram characteristics of conventions and complexity. Descriptive analyses examine students’ ability to understand scientific diagrams and which diagram characteristics cause the most difficulty. We also compared groups with low and high DCA scores to evaluate how students at different levels of comprehension ability are affected by diagram characteristics. Results show relatively poor DCA; the average total test score was only 69.5%. The conventions used in a diagram also affected diagram comprehension, and results show students had the most difficulty comprehending diagrams using a letter or numbering system, where arbitrary letters/numbers were used to signify objects and diagrams using cut-outs that showed cross sections and magnified interior views. Additionally, students’ comprehension was higher on diagrams with higher complexity (i.e., more types of conventions used), potentially indicating students are able to take advantage of the supports that different conventions provide. Implications for instruction are identified.
