  • Biology syllabi lack learner-centered principles

    Biology syllabi lack learner-centered principles

    A course syllabus serves as a road map for navigating the upcoming term and content that will be covered, but researchers believe it could support students’ self-directed learning as well.

    A November study published in the Journal of Research in Science Teaching, authored by a team of faculty from Auburn University and the University of Alabama at Birmingham, shows few introductory biology syllabi engage students in effective study habits or encourage help-seeking behaviors, instead favoring content.

    The research highlights opportunities to address the hidden curriculum of higher education and support success for historically marginalized students.

    What’s the need: Some college students lack effective study habits, and these gaps are often a piece of larger equity concerns for marginalized groups, highlighting limited opportunities or resources for underprivileged communities.

    Introductory science, technology, engineering and mathematics courses, in particular, often serve as gatekeepers, limiting which students can pursue these degree programs and resulting in less diverse STEM degree attainment.

    Today’s college students also demonstrate less college readiness in their academic skills, due in part to remote instruction as a result of the COVID-19 pandemic.

    Often, colleges or universities will create co-curricular interventions such as workshops to teach these skills or introduce best practices in a first-year seminar course. While these can be effective, institutions may lack the resources or time to deliver the interventions, which researchers say underscores a need for alternative strategies that reach students.

    Researchers theorized that embedding within the syllabus explicit instruction to promote three skills—study behaviors, metacognitive evaluation or academic help-seeking—could impact student success.

    Methodology: Researchers evaluated 115 introductory biology syllabi from 94 unique institutions, including 48 percent research-intensive institutions, 29 percent minority-serving institutions, 72 percent publics and 61 percent with enrollment over 10,000 students.

    A Deeper Look at STEM Syllabi

    A Worcester Polytechnic Institute study found instructors could help create a more inclusive learning environment in STEM courses through tailoring their syllabus to feature elements like materials from diverse scholars and accessibility statements. Read more here.

    One engineering professor at the University of Massachusetts at Amherst redesigned her syllabus as a zine, or miniature magazine, to promote student engagement and build community in the classroom.

    Syllabi were categorized by having the presence of study behaviors, academic help-seeking and metacognition suggestions; the type of suggestions of those three factors; and the quality of these recommendations (effective or ineffective).

    Further syllabus analysis covered four factors to gauge how learner-centered they were, including having clear and appropriate learning goals and objectives, aligned and define assessment activities, a logically sequenced course schedule, and a positive and organized learning environment. Each syllabus was awarded between zero and 48 points, with higher scores indicating they were more learner-centered.

    The findings: Among the 115 syllabi evaluated, only 14 percent earned a score of at least 31 to be considered learner-centered. Around three in 10 syllabi were considered “content-centered,” earning a score of 16 or less. Researchers theorized faculty may lack time or interest when creating their own syllabi, instead relying on templates from the institution or previously generated documents.

    Design by Ashley Mowreader

    Only 3.5 percent of syllabi showed evidence of reducing opportunity gaps in STEM courses, which researchers defined as de-emphasizing course rules, encouraging the use of external resources for continued learning outside the classroom and emphasizing the role of students in their own learning.

    “Most of the syllabi in our sample provided learning resources but focused primarily on course policies and did not address students as engaged learners,” according to the study.

    A majority of syllabi did offer suggestions for study behaviors, metacognition or approaches for academic help-seeking (61 percent), although the greatest share of these only addressed help-seeking (45 percent). When the syllabus did share advice to seek help, many just provided a list of resources, and fewer encouraged students to utilize them.

    “Only 17.9 percent of syllabi provided a listing of academic help-seeking resources, encouragement to use those resources, and an explanation on how to use those resources,” researchers wrote, with the explanation piece critical for addressing equity gaps and the hidden curriculum of higher education.

    Of the syllabi that provided recommendations for students’ study behaviors, a significant number gave students unhelpful advice or shared practices that are not affirmed with research.

    “We found that most biology syllabi endorsed effective study strategies such as self-testing and spacing,” researchers wrote. “However, we also found that syllabi recommended strategies that have been described as ineffective for long-term learning (e.g., re-reading textbooks and re-writing notes).”

    Twenty-nine percent of syllabi recommended only effective, evidence-based study habits. A greater share (42 percent) offered both effective and ineffective techniques, and 24 percent only offered ineffective behaviors.

    Just because the syllabus was lacking details on how to study or practice metacognition doesn’t mean it was absent from the class entirely, researchers noted, as instructors may discuss these topics in class or provide additional resources with this information. This presents an opportunity for instructors to make themselves more aware of evidence-based practices to close equity gaps and bring the syllabus into better alignment with their pedagogy, according to the study.

  • Butterflies and Biology for Life

    Butterflies and Biology for Life

    Reading Time: 4 minutes

    When I was in sixth grade, my homeroom teacher brought monarch caterpillars into our classroom. One of our homework assignments was to walk around our backyard and find milkweed (the only kind of plant monarch caterpillars eat) to feed our caterpillars. Now, over 25 years later, I still clearly remember the excitement of hunting around in my backyard to find milkweed and checking every day to see the metamorphosis from caterpillar to butterfly.

    You might say that raising monarch caterpillars gave me the bug to want to be a biologist.

    An early interest in biology sparks a lifelong dedication

    As the years went by, my interest in biology didn’t wane. In college, molecular biology became my primary focus area. During graduate school and beyond, I trained in both molecular biology and the learning sciences, settling into a career in biology education. I taught Non-Majors and Majors Biology while running a research lab dedicated to understanding how people learn biology.

    A lack of enthusiasm from students

    When I taught Non-Majors Biology, I noticed a concerning trend among my students: All in all, they didn’t like biology.

    That may be too gentle. The comments from an “introduce yourself” activity that I use in the first week of class revealed that most of my students were either afraid to take a biology class, thought the subject was boring, or didn’t think they could succeed at it. Some people even flat-out admitted they hated the subject.

    Now, as a self-professed biology nerd, those comments took me aback. As a learning sciences researcher, I wanted to know why there were such pervasive negative feelings about biology. As a biology educator, I wanted to know what to do about it.

    A common point of view

    Negative perceptions around biology are common, driving people away from engaging with the big biology issues we face today. Lack of knowledge around scientific topics can make it easier to be duped by misinformation, leading one to potentially make decisions against their own best interests. We see this with issues ranging from climate change to vaccines.

    Acknowledging that biology is all around us is important not only because it enriches our lives, but because it’s also important to the health and welfare of our society. Biology is everywhere, and engagement starts with reimagining how we think about biology’s role in our lives. It’s about reigniting wonder and emphasizing  relevance. It’s about giving students the chance to learn biological material in a way that makes sense to them. When we start to make connections between the classroom and the real world,  it becomes easier to engage with bigger concepts and ideas.

    Connecting biology to the everyday

    Let’s look at hand washing, as an example of how to relate lipid biochemistry to our everyday routines.

    Okay, fine, we all know we’re supposed to do it, and yet nasty microorganisms like norovirus (transmitted mainly by the fecal-oral route, ahem) still tend to spread rampantly. Isn’t hand sanitizer sufficient? Or Lysol? The soap dispenser is out again — does it matter?

    According to the Centers for Disease Control, hand sanitizer doesn’t work well against norovirus. Think of norovirus as wearing a protective coat — hand sanitizer doesn’t penetrate, and since the virus doesn’t readily dry out on surfaces, it remains ready to infect on the surface of the skin. In order to effectively remove the virus, you have to use soap and water and rub your hands together. Why?

    Soap particles have water-repellant and water-loving components. Those water-repellant portions, combined with rubbing your hands back in forth, causes the virus to break apart. The soap particles surround the bits of virus, and water washes it away.

    If I talked about the structure of soap as a fatty acid with a carboxylic acid functional group, sodium ion, and fatty acid tail, and how with other fatty acids, it forms a micelle in water, students’ eyes would glaze over. On the contrast, breaking down the basics of why hand-washing works to illustrate the biochemistry proves far more interesting.

    Impacting student perceptions

    When biological principles are applied to our daily lives, they become inherently interesting. When students realize they can understand the biological principles behind their daily experiences, it becomes accessible. By viewing biology through a personal lens, students learn to appreciate rather than hate the subject.

    When students see biology everywhere, as an integral part of their lives, they are more likely to engage. As they engage, they realize they can understand biology, and that it’s actually interesting.

    Think back to the opening example — my homework was looking in my backyard for milkweed to feed to the classroom caterpillars. Biology was relatable and accessible and that made it exciting. That’s the driving framework behind my biology education practice. I always consider the relevancy in students’ lives as the main touchstone in my teaching practice.
