Experience Based Lab Introductions
Experience Based Lab Introductions is a strategy I use to get students to start thinking about their prior knowledge and how it can be applied to a problem or challenge. For example, I use the story about Who Polluted the Clark Fork to set the stage for our water filter lab. The story allows students to use their knowledge-base to answer simple questions throughout the story. As the activity continues, I see students' perspectives change as more elements and variables are added to the story. The stories peak students' interest and bring a call to action into a classroom activity. This strategy is embedded in the Conceptual Change Model, where I'm trying to expose students' beliefs, confront and accommodate those beliefs, and then extend the concept to help students move beyond their misconceptions.
QR codes are simple and easy to make codes that allow classroom resources, like videos, websites, and assignments to be accessed with little effort. These codes can be made easily using the Chrome extension goo.gl URL shortener or a website like qrstuff.com. They can be displayed on an interactive whiteboard, printed on an assignment, or printed and taped to a wall at a station or on a lab desk. QR codes take away the barrier of typing in long URLs or shortened website links, and get students to resources quickly.
Grade Contracts are a strategy I use to assess my students' progress towards mastery of defined sets of content and skill objectives and to provide feedback on their development at the end of each level in my blended learning class. Students review the mastery requirements for each level and decide whether they will pursue an "A," "B," "C," or "D" contract; in so doing, they understand and commit to what they must know and be able to do in order to earn the letter grade of the contracts they have chosen. Grade Contracts eliminate the superficiality of number grades on individual assignments and focus my students' attention on authentic demonstrations of mastery over time. This strategy also empowers my students to challenge themselves and to monitor and take responsibility for their own learning, which is an essential mindset shift in my largely self-paced class.
Partner Labs are investigatons that require more than one student in the group. These labs require my students to work together to come up with a solution to a problem or to conduct an experiment. Some of my favorite activities to do with my students are The Virtual Thinking Project (PBL), and the Solar Oven and Cooler design projects. These projects require students to work collaboratively together, often in the lab, to engineer solutions to problems or to perform experiments.
