Prevailing Questions and Methodologies in Biology Education Research: A Longitudinal Analysis of Research in CBE-Life Sciences Education and at the Society for the Advancement of Biology Education Research.

CBE Life Sci Educ 2019 03;18(1):ar9

Department of Molecular Biology and Biochemistry, University of California, Irvine, Irvine, CA 92697.

Biology education research (BER) is a growing field, as evidenced by the increasing number of publications in CBE-Life Sciences Education ( LSE) and expanding participation at the Society for the Advancement of Biology Education Research (SABER) annual meetings. To facilitate an introspective and reflective discussion on how research within LSE and at SABER has matured, we conducted a content analysis of LSE research articles ( n = 339, from 2002 to 2015) and SABER abstracts ( n = 652, from 2011 to 2015) to examine three related intraresearch parameters: research questions, study contexts, and methodologies. Qualitative data analysis took a combination of deductive and inductive approaches, followed by statistical analyses to determine the correlations among different parameters. Read More

FAIL Is Not a Four-Letter Word: A Theoretical Framework for Exploring Undergraduate Students' Approaches to Academic Challenge and Responses to Failure in STEM Learning Environments.

CBE Life Sci Educ 2019 03;18(1):ar11

Department of Ecology and Evolutionary Biology, University of Colorado, Boulder, Boulder CO 80309.

Navigating scientific challenges, persevering through difficulties, and coping with failure are considered hallmarks of a successful scientist. However, relatively few studies investigate how undergraduate science, technology, engineering, and mathematics (STEM) students develop these skills and dispositions or how instructors can facilitate this development in undergraduate STEM learning contexts. This is a critical gap, because the unique cultures and practices found in STEM classrooms are likely to influence how students approach challenges and deal with failures, both during their STEM education and in the years that follow.

A Model for Holistic Review in Graduate Admissions That Decouples the GRE from Race, Ethnicity, and Gender.

CBE Life Sci Educ 2019 03;18(1):ar7

Deans' Office, The University of Texas MD Anderson Cancer Center UTHealth Graduate School of Biomedical Sciences, Houston, TX 77030.

Graduate schools around the United States are working to improve access to science, technology, engineering, and mathematics (STEM) in a manner that reflects local and national demographics. The admissions process has been the focus of examination, as it is a potential bottleneck for entry into STEM. Standardized tests are widely used as part of the decision-making process; thus, we examined the Graduate Record Examination (GRE) in two models of applicant review: metrics-based applicant review and holistic applicant review to understand whether it affected applicant demographics at The University of Texas MD Anderson Cancer Center UTHealth Graduate School of Biomedical Sciences.

The Impact of a Pedagogy Course on the Teaching Beliefs of Inexperienced Graduate Teaching Assistants.

Authors:
Star W Lee

CBE Life Sci Educ 2019 03;18(1):ar5

Department of Evolution, Ecology, & Organismal Biology, University of California, Riverside, Riverside, CA 92521.

There has been little attention given to teaching beliefs of graduate teaching assistants (GTAs), even though they represent the primary teaching workforce for undergraduate students in discussion and laboratory sections at many research universities. Secondary school education studies have shown that teaching beliefs are malleable and can be shaped by professional development, particularly for inexperienced teachers. This study characterized inexperienced GTAs' teaching beliefs about student learning and how they change with a science-specific pedagogy course that emphasized student learning. Read More

Identifying Troublesome Jargon in Biology: Discrepancies between Student Performance and Perceived Understanding.

CBE Life Sci Educ 2019 03;18(1):ar6

Department of Zoology, University of British Columbia, Vancouver, BC V6T 1Z4, Canada.

The excessive "jargon" load in biology may be a hurdle for developing conceptual understanding as well as achieving core competencies such as scientific literacy and communication. Little work has been done to characterize student understanding of biology--specific jargon. To address this issue, we aimed to determine the types of biology jargon terms that students struggle with most, the alignment between students' perceived understanding and performance defining the terms, and common errors in student-provided definitions.

Molecular Concepts Adaptive Assessment (MCAA) Characterizes Undergraduate Misconceptions about Molecular Emergence.

CBE Life Sci Educ 2019 03;18(1):ar4

Institute of Medical Science, University of Toronto, Toronto, ON M5S 1A8, Canada.

This paper discusses the results of two experiments assessing undergraduate students' beliefs about the random nature of molecular environments. Experiment 1 involved the implementation of a pilot adaptive assessment ( n = 773) and focus group discussions with undergraduate students enrolled in first- through third-year biology courses; experiment 2 involved the distribution of the redesigned adaptive assessment to the same population of students in three consecutive years ( n = 1170). The overarching goal of the study was to provide a detailed characterization of learners' perceptions and beliefs regarding molecular agency, environments, and diffusion and whether or not those beliefs change over time.

GenBio-MAPS: A Programmatic Assessment to Measure Student Understanding of Vision and Change Core Concepts across General Biology Programs.

CBE Life Sci Educ 2019 03;18(1):ar1

School of Life Sciences, Arizona State University, Tempe, AZ 85287.

The Vision and Change report provides a nationally agreed upon framework of core concepts that undergraduate biology students should master by graduation. While identifying these concepts was an important first step, departments also need ways to measure the extent to which students understand these concepts. Here, we present the General Biology-Measuring Achievement and Progression in Science (GenBio-MAPS) assessment as a tool to measure student understanding of the core concepts at key time points in a biology degree program.

The Graph Rubric: Development of a Teaching, Learning, and Research Tool.

CBE Life Sci Educ 2018 12;17(4):ar65

Department of Biological Sciences, Purdue University, West Lafayette, IN 47907.

As undergraduate biology curricula increasingly aim to provide students with access to courses and experiences that engage them in the practices of science, tools are needed for instruction, evaluation, and research around student learning. One of the important skills for undergraduate biology students to master is the selection and creation of appropriate graphs to summarize data they acquire through investigations in their course work and research experiences. Graphing is a complex skill, and there are few, discipline-informed tools available for instructors, students, and researchers to use. Read More

Authentic Inquiry through Modeling in Biology (AIM-Bio): An Introductory Laboratory Curriculum That Increases Undergraduates' Scientific Agency and Skills.

CBE Life Sci Educ 2018 12;17(4):ar63

Department of Molecular and Cellular Biology, University of Arizona, Tucson, AZ 85721.

Providing opportunities for science, technology, engineering, and mathematics undergraduates to engage in authentic scientific practices is likely to influence their view of science and may impact their decision to persist through graduation. Laboratory courses provide a natural place to introduce students to scientific practices, but existing curricula often miss this opportunity by focusing on confirming science content rather than exploring authentic questions. Integrating authentic science within laboratory courses is particularly challenging at high-enrollment institutions and community colleges, where access to research-active faculty may be limiting.

CBE Life Sci Educ 2018 12;17(4):ar61

Center for Integration of Science and Industry, Bentley University, Waltham, MA 02452.

The majority of students who enroll in undergraduate biology courses will eventually be employed in non-STEM (science, technology, engineering, and mathematics) business occupations. This work explores how representations of industry in undergraduate biology textbooks could impact STEM learning for these students and their ability to apply this learning in their chosen work. We used text analysis to identify passages with references to industry in 29 textbooks. Read More

Student Learning Outcomes and Attitudes Using Three Methods of Group Formation in a Nonmajors Biology Class.

CBE Life Sci Educ 2018 12;17(4):ar60

Center for Evolution and Medicine, Arizona State University, Tempe, AZ 85281.

Group work is often a key component of student-centered pedagogies, but there is conflicting evidence about what types of groups provide the most benefit for undergraduate students. We investigated student learning outcomes and attitudes toward working in groups when students were assigned to groups using different methods in a large-enrollment, student-centered class. We were particularly interested in how students entering the class with different levels of competence in biology performed in homogeneous or heterogeneous groups, and what types of group compositions were formed using different methods of group formation.

Becoming a "Science Person": Faculty Recognition and the Development of Cultural Capital in the Context of Undergraduate Biology Research.

CBE Life Sci Educ 2018 12;17(4):ar62

Department of Anthropology, University of Wyoming, Laramie, WY 82071.

We argue that cultural capital plays an underexamined role in students' recognition as budding scientists by faculty. By triangulating interview data from undergraduates and faculty mentors in a multi-institutional biology research network, we identified a set of intersecting domains of capital that help render students recognizable to faculty. We argue that faculty recognition often reflects a (mis)alignment between the cultural capital that students possess and display and what faculty expect to see. Read More

Probing the Relevance of Chemical Identity Thinking in Biochemical Contexts.

CBE Life Sci Educ 2018 12;17(4):ar58

Department of Chemistry, University of Massachusetts Boston, Boston, MA 02125.

The solving of problems in biochemistry often uses concepts from multiple disciplines such as chemistry and biology. Chemical identity (CI) is a foundational concept in the field of chemistry, and the knowledge, thinking, and practices associated with CI are used to answer the following questions: "What is this substance?" and "How is it different from other substances?" In this study, we examined the relevance of CI in biochemical contexts and first explored the ways in which practicing biochemists consider CI relevant in their work. These responses informed the development of creative exercises (CEs) given to second--semester biochemistry students. Read More

"Is This Class Hard?" Defining and Analyzing Academic Rigor from a Learner's Perspective.

CBE Life Sci Educ 2018 12;17(4):ar59

Department of Biological Sciences, Bethel University, St. Paul, MN 55112.

Despite its value in higher education, academic rigor is a challenging construct to define for instructor and students alike. How do students perceive academic rigor in their biology course work? Using qualitative surveys, we asked students to identify "easy" or "hard" courses and define which aspects of these learning experiences contributed to their perceptions of academic rigor. The 100-level students defined hard courses primarily in affective terms, responding to stressors such as fast pacing, high workload, unclear relevance to their life or careers, and low faculty support.

Faculty Beliefs about Intelligence Are Related to the Adoption of Active-Learning Practices.

CBE Life Sci Educ 2018 09;17(3):ar47

Department of Ecology and Evolutionary Biology, Yale University, New Haven, CT 06511.

Mounting evidence of the efficacy of active learning has prompted educators to consider adoption of these practices in college-level classrooms. One tenet of active learning is that most, if not all, students have the ability to learn. Instructors' perspectives on learning, however, may or may not be aligned with this. Read More

Developing an Analytical Framework to Characterize Student Reasoning about Complex Processes.

CBE Life Sci Educ 2018 09;17(3):ar49

Lyman Briggs College, Michigan State University, East Lansing, MI 48824.

Real-world processes are complex and require ideas from multiple disciplines to be explained. However, many science courses offer limited opportunities for students to synthesize scientific ideas into coherent explanations. In this study, we investigated how students constructed causal explanations of complex phenomena to better understand the ways they approach this practice. Read More

Building a Sustainable National Infrastructure to Expand Research Mentor Training.

CBE Life Sci Educ 2018 09;17(3):ar48

Institute for Clinical and Translational Research, University of Wisconsin-Madison, Madison, WI 53705.

An evidence-based research mentor training (RMT) curricular series has been shown to improve the knowledge and skills of research mentors across disciplines and career stages. A train-the-trainer model was used in the context of several targeted approaches aimed at sustainability to support national dissemination of RMT and expand the network of facilitators prepared to implement the curricula. These infrastructure elements included 1) an expansion initiative to increase the number of trained facilitators able to deliver train-the-trainer workshops nationwide; 2) adaptation of RMT curricula for multiple audiences and career stages to increase accessibility; 3) implementation resources to support facilitators and help them overcome implementation barriers; and 4) standardized evaluation of training.

Students Are Rarely Independent: When, Why, and How to Use Random Effects in Discipline-Based Education Research.

Authors:
Elli Theobald

CBE Life Sci Educ 2018 09;17(3):rm2

Department of Biology, University of Washington, Seattle, WA 98195.

Discipline-based education researchers have a natural laboratory-classrooms, programs, colleges, and universities. Studies that administer treatments to multiple sections, in multiple years, or at multiple institutions are particularly compelling for two reasons: first, the sample sizes increase, and second, the implementation of the treatments can be intentionally designed and carefully monitored, potentially negating the need for additional control variables. However, when studies are implemented in this way, the observations on students are not completely independent; rather, students are clustered in sections, terms, years, or other factors. Read More

Learning Strategies for First-Year Biology: Toward Moving the "Murky Middle".

CBE Life Sci Educ 2018 09;17(3):ar42

Department of Chemistry, University of Pretoria, Pretoria 0002, South Africa.

Higher education faces the challenge of high student attrition, which is especially disconcerting if associated with low participation rates, as is the case in South Africa. Recently, the use of learning analytics has increased, enabling institutions to make data-informed decisions to improve teaching, learning, and student success. Most of the literature thus far has focused on "at-risk" students. Read More

Catching the Wave: Are Biology Graduate Students on Board with Evidence-Based Teaching?

CBE Life Sci Educ 2018 09;17(3):ar43

Biology Department, Portland State University, Portland, OR 97201.

Graduate students hold a critical role in responding to national calls for increased adoption of evidence-based teaching (EBT) in undergraduate classrooms, as they not only serve as teaching assistants, but also represent the pool from which future faculty will emerge. Through interviews with 32 biology graduate students from 25 institutions nationwide, we sought to understand the progress these graduate students are making in adopting EBT through qualitative exploration of their perceptions of and experiences with both EBT and instructional professional development. Initial inductive content analysis of interview transcripts guided the holistic placement of participants within stages of Rogers's diffusions of innovations model, which we use as a theoretical framework to describe the progress of EBT adoption.

Improving Undergraduate Life Science Education for the Biosciences Workforce: Overcoming the Disconnect between Educators and Industry.

CBE Life Sci Educ 2018 09;17(3):es12

Department of Biology, Loyola University Maryland, Baltimore, MD 21210.

The BioHealth Capital Region (Maryland, Virginia, and Washington, DC; BHCR) is flush with colleges and universities training students in science, technology, engineering, and mathematics disciplines and has one of the most highly educated workforces in the United States. However, current educational approaches and business recruitment tactics are not drawing sufficient talent to sustain the bioscience workforce pipeline. Surveys conducted by the Mid-Atlantic Biology Research and Career Network identified a disconnect between stakeholders who are key to educating, training, and hiring college and university graduates, resulting in several impediments to workforce development in the BHCR: 1) students are underinformed or unaware of bioscience opportunities before entering college and remain so at graduation; 2) students are not job ready at the time of graduation; 3) students are mentored to pursue education beyond what is needed and are therefore overqualified (by degree) for most of the available jobs in the region; 4) undergraduate programs generally lack any focus on workforce development; and 5) few industry-academic partnerships with undergraduate institutions exist in the region.

Peer vs. Self-Grading of Practice Exams: Which Is Better?

CBE Life Sci Educ 2018 09;17(3):es44

Department of Biology, University of Washington, Seattle, WA 98105.

Practice exams are a type of deliberate practice that have been shown to improve student course performance. Deliberate practice differs from other types of practice, because it is targeted, mentally challenging, can be repeated, and requires feedback. Providing frequent instructor feedback to students, particularly in large classes, can be prohibitive. Read More
