Project Based Learning
During the last few semesters, a small survey has been deployed at Bradley University where students were to describe and classify items of litter that they found. The purposes of the surveys were to get students thinking about some of the chemical implications of solid waste and give the students some experience with a citizen science project. The most recent iteration of the survey, and some of its results, are described.
Kristen Drury came up with a fun new project for her class, “Create a Game: Shark Tank Presentation.”
Context-based chemistry aims to make chemistry learning more meaningful for students. With an emphasis on inquiry-based activities, context-based chemistry improves student interest and motivation in chemistry by linking content to real-world situations. Though the idea has been around for over 20 years, researchers are still learning the best strategies for teaching context-based chemistry. Here, we will explore some of the benefits and challenges unearthed up until this point.
The International Scholastic Journal of Science is an online, open-access journal that provides the opportunity for secondary students to publish entry-level research and become part of the scientific process. In this blog post I will share information about ISJOS and encourage you to find students that are interested in publishing.
The author shares a series of resources she has created that are built around a post here on ChemEd X about popping a balloon with an orange peel and the concept of polarity.
My first big project my students engaged in during the 2013-14 school year was, at best, a mediocre experience and, at worst, a giant waste of valuable instructional time we'd never get back.
In an earlier post, I discuss some of my unit planning that (I hope!) further breaks down a few of these misconceptions - my students are not teaching themselves on google. They are weaving back and forth between learning content and the larger reason for learning the content.
However, every single one of these comments above are valid. It is really difficult work to ultimately balance individual accountability and group accountability. Every student needs to master basic stoichiometry before they leave my general chemistry course.
Check out this overview of what a PBL unit has looked like in my classroom. I provide concrete examples and an outline of how I plan a project.
These tenets set PBL (the big once-per-semester projects) apart from day to day activities and inquiry:
PBL poses an authentic problem with multiple solutions.
PBL requires core subject knowledge to propose solutions to a problem to an authentic audience.
