Pick Your Poison: A Semester-Long Case Study for Undergraduate Toxicology

Joshua P. Gray*

Version: 1.0

Published on 12.2022

The ability to collate information from diverse scientific resources and effectively employ scientific writing is an essential skill for scientists. This lesson describes a semester-long project entitled “Pick Your Poison,” which is designed for use in a one-semester Toxicology course. Students are each assigned to or choose their own individual toxicant as a case study from a pre-selected list of toxicants (poisons) that align with the theme of the course. As content is covered in the course, students complete ten scaffolded, low-stakes writing modules that are shared with groupmates of 4–5 students. Each module covers a major feature of the toxicant, such as chemical features, characteristics of absorption, distribution, metabolism, and elimination (ADME), and organ-specific toxicities. Students share their work with their group mates and the instructor, peer review one another’s work, and then edit their original post as appropriate to produce a concise, 3–4 paragraph product. At the end of the course, students compile their writing modules into an article in the format of the Encyclopedia of Toxicology. This project can be adapted to any toxicology course through alteration of the content and number of modules and/or the type of final deliverable. Several evidence-based and inclusive teaching practices are included, such as writing-to-learn, peer review, and low-stakes assessments.

Video Making Tips for Laboratory Instructors

Joyce E. Patrick*, John Z. Zhu

Version: 1.0

Published on 11.2022

Demonstration videos are an excellent way to introduce students to new laboratory techniques, but many available videos are of low quality, too long, lack human diversity, and the main narrator is someone other than the instructor of the course. Videos may feature terminology and equipment different from what the students will use and the availability of the video is also not controlled by the lab instructor. Lab instructors can enhance the lab experience of students by making their own demonstrations videos. The current cell phone camera technology allows instructors to make custom videos. We watched many successful how-to style YouTube videos and distilled several techniques. We then applied these techniques to make more engaging videos for our students. Many of our videos have found success on YouTube. In this paper, we break down our video making techniques for demonstrating laboratory equipment and protocols. We hope the readers will find inspiration to make their own demonstration videos to aide their students.

Change to CourseSource page charges

October 19, 2022

Dear CourseSource community,

Since its inception, publishing in CourseSource has been free! We regret that the time has come to charge for publications; CourseSource is supported by grants and donations, and our budget no longer allows us to take on the full burden of publication charges. We will be implementing a flat fee of $400 per article beginning in January 2023. We have budgeted some funds to assist authors with costs—both a reduced fee of $250 or a complete waiver, depending on circumstances. We also will implement a group discount program in which an institution or a group from a collaborative grant can pay $1000 per year and publish as many articles as they would like.

Thank you for your continued support.

Publish Your Educational Toxicology Exercises in CourseSource!

August 9, 2022

CourseSource has recently partnered with the Society of Toxicology (SOT), and we are recruiting submissions that utilize the Toxicology Learning Framework to add to the toxicology collection!

Interested in sharing your work? Check out this video recording of the CourseSource workshop held at the 2022 SOT Annual Meeting: Publishing Educational Toxicology Exercises in CourseSource: A Step-by-Step Workshop for Preparing Your Manuscript. This workshop equips educators to use CourseSource and inspires them to submit their inclusive, evidence-based educational resources. In the first part of the workshop, Erin Vinson, the former managing editor of CourseSource, reviews the design of the CourseSource website and its features, and the various types for submissions. In the second part, Lauren Aleksunes (“Repurposing Drugs as Countermeasures for Chemical Weapons: An Interactive Training for Undergraduate Students”), Joshua Gray (“Pick Your Poison: A Semester-Long Toxicology Project Integrating Toxicology Core Concepts and Scientific Communication”), and Mindy Reynolds (“A Case Study Approach to the One Environmental Health Hypothesis”) discuss their curricula and the preparation of CourseSource manuscripts. The last section provides time for participants to prepare their own concepts for submission.

We look forward to seeing your submissions!
