Evaluating the Quick Fix: Weight Loss Drugs and Cellular Respiration

One key to student success in introductory and cell biology courses is a foundational knowledge of cellular respiration. This is a content area in which students often harbor misconceptions that make cellular respiration particularly challenging to teach. Conventional approaches presenting cellular respiration as a complex series of isolated steps creates a situation where students tend to memorize the steps but fail to appreciate the bigger picture of how cells transform and utilize energy. Instructors frequently struggle to find ways to motivate students and encourage deeper learning. The learning goals of this cellular respiration lesson are to understand energy transfer in a biological system, develop data analysis skills, practice hypothesis generation, and appreciate the importance of cellular respiration in everyday life. These goals are achieved by using a case study as the focal point. The case-based lesson is supported with student-centered instructional strategies, such as individual and group activity sheets, in-class group discussions and debate, and in-class clicker questions. This lesson has been implemented at two institutions in large enrollment introductory biology courses and in a smaller upper-division biochemistry course.

Module 1: Discovering Your Family's “Botanical History.”

We all know that understanding family history is important to understanding our place in the world. To help students learn to appreciate plants, this activity will connect family memories to specific plants that were important to them or to their ancestors. This is referred to as “botanical history.” Students will interview family members to identify a specific plant they will use for the remaining nine modules. The plant the students choose is ideally one that holds historical significance to their family (e.g., an apple tree that has provided fruits for many generations, or a houseplant that has been divided or shared on special occasions). The students will then share their stories with the class and compare the plants they have chosen with their classmates.

Module 2: Opening Your Eyes to the Diversity of Plants

This activity picks up from Module 1 where students chose the plant they wanted to represent their botanical history. In that module, they each identified their plant’s family and were given its scientific name. Module 2 provides students with an overview of the four major groups of land plants (bryophytes, ferns and allies, gymnosperms, and angiosperms), as well as familiarizing students with organisms that are often mistaken for plants (e.g., fungi, lichens, algae). Students will also be introduced to the Linnaean hierarchy as applied to major plant groups. Once students become familiar with plant characteristics and distinguishing features for major groups, they will be able to identify the group their own plant belongs to.

Module 3: What on Earth is a Herbarium?

The goal of this activity is to introduce students to herbarium specimens and why they are an important source of information. The emphasis of this activity is on examining the types of data that specimens provide and how this data can be used to answer questions in biology (e.g., species distributions, ecological interactions, genetics) and anthropology (ethnobotany). Students will explore these data by following the life of Ynés Mexía, an important botanical collector working at the turn of the 20th century. Students will study her specimens to identify the various types of data they contain.

Module 4: What Kind of Data Goes in a Field Notebook?

The goal of this activity is to introduce students to biological field notebooks and how they are used by scientists during field work. Specifically, students will learn what a botanist collecting plants in the field will record in their notebook, and how this information is then used to produce a formal herbarium specimen with detailed record label. This activity will prepare students for collecting their own herbarium specimens with regard to the types of data they need to record.

Module 5: How to Collect and Press Plants in the Field

This activity will guide students through the process of collecting fresh plant material that will be transformed into a permanent herbarium specimen. Students will make a specimen for the plant they chose to represent their family’s botanical history. Each student will use a field press to preserve the plant they collect and record field notes about the plant. This information will be used to prepare a permanent record label that will appear on the herbarium specimen.

A Scavenger Hunt into The Maple Tree Species Diversity

This lesson plan aims to provide students with an interactive experience with nature, focusing on maple trees' diversity and ecological importance in urban forests. Maple trees, belonging to the genus Acer in the family Sapindaceae, are significant in temperate regions of the Northern Hemisphere, especially in Autumn. Students engage with nature through an interactive scavenger hunt using identification cards and the iNaturalist app to document and analyze leaf characteristics. This lesson plan focuses on five common species found on the East Coast: Sugar Maple (Acer saccharum), Silver Maple (Acer saccharinum), Red Maple (Acer rubrum), Norway Maple (Acer platanoides), and Japanese Maple (Acer palmatum). The goal is to enhance students' understanding of tree diversity, leaf identification, evolutionary relationships, and ecological roles. This lesson plan results from the collaboration between Chestnut Hill College and Our Mother of Consolation School in Philadelphia, PA, funded by the Connelly Foundation.

Learning R for Biologists: A Mini Course Grab-Bag for Instructors

As biology becomes more data driven, teaching students data literacy skills has become central to biology curriculum. Despite a wealth of online resources that teach researchers how to use R, there are few that offer practical laboratory-based exercises, with teaching resources such as keys, learning objectives, and assessment materials. Here, we present a modular set of lessons and lab activities to help teach R through the platform of RStudio. Both software applications are free and open source making this curriculum highly accessible across various institutions. This curriculum was developed over several years of teaching a graduate level computational biology course. In response to the pandemic, the class was shifted to be completely online. These resources were then migrated to GitHub to make them broadly accessible to anyone wanting to learn R for the analysis of biological datasets. In the following year, these resources were used to teach the course in a flipped format, which is the lesson plan presented here. In general, students responded well to the flipped format, which used class time to conduct live coding demos and work through challenges with the instructor and teaching assistant. Overall, students were able to use these skills to practice analyzing and interpreting data, as well as producing publication quality graphics. While the modules presented range from very basic, doing simple summary statistics and plotting, to quite advanced, where R is integrated onto the command line, teachers should feel free to pick and choose which elements to incorporate into their own curriculum.

Bioinformatics is a BLAST: Engaging First-Year Biology Students on Campus Biodiversity Using DNA Barcoding

In order to introduce students to the concept of molecular diversity, we developed a short, engaging online lesson using basic bioinformatics techniques. Students were introduced to basic bioinformatics while learning about local on-campus species diversity by 1) identifying species based on a given sequence (performing Basic Local Alignment Search Tool [BLAST] analysis) and 2) researching and documenting the natural history of each species identified in a concise write-up. To assess the student’s perception of this lesson, we surveyed students using a Likert scale and asking them to elaborate in written reflection on this activity. When combined, student responses indicated that 94% of students agreed this lesson helped them understand DNA barcoding and how it is used to identify species. The majority of students, 89.5%, reported they enjoyed the lesson and mainly provided positive feedback, including “It really opened my eyes to different species on campus by looking at DNA sequences”, “I loved searching information and discovering all this new information from a DNA sequence”, and finally, “the database was fun to navigate and identifying species felt like a cool puzzle.” Our results indicate this lesson both engaged and informed students on the use of DNA barcoding as a tool to identify local species biodiversity.

What is Speciation, How Does It Occur, and Why Is It Important for Conservation?

Speciation provides a framework for classifying biodiversity on Earth and is a central concept in evolutionary biology. To help undergraduate students learn about speciation, we designed a student-centered lesson that uses active-learning techniques (e.g., clicker questions, small group work, and whole class discussion) and compares multiple species concepts (morphological, biological, and phylogenetic) using giraffes as an example. Giraffes were chosen as the focus of this lesson because they are familiar and have broad appeal to students; are in danger of becoming extinct; and have ecological, economic, and cultural importance. Students also learn about contemporary giraffe conservation issues and the current debate in the literature regarding the total number of giraffe species. Students then apply their knowledge by working in small groups on speciation scenarios that highlight organisms across the tree of life. Student understanding is assessed using multiple-choice pre/post-test questions, in-class clicker questions with peer discussion, and exam questions. Here we provide details about the lesson and report that student learning is improved.
