Self-Paced Lab Documentation
Organizing labs that span over a number of classes requires a substantial amount of pre-planning. The benefits of proper Lab Documentation are potentially enormous for students. Lab Documentation ensures that I can follow students through every step of the lab process even when groups are completing different segments within varying timeframes. Students develop lab procedures on Google Docs, create charts/tables/graphs on Google Sheets, and compile lab portfolios on wikispaces. By hosting their work on Google Apps for Education, my students can easily collaborate with group mates and me on a lab activity over the course of a week or more. During this time, I can ask probing questions, offer insight on effective lab methods and tactics, work directly on their documents, and help students record their labs with media-capture tools. Being able to analyze video of the lab procedure next to the results it produced provides my students a great means to produce high-quality lab reports, which they can publish to the web and their group wikispace pages.
Planning is an essential part of a blended teacher’s practice. In blended environments, where students can be at different points in a course on various modalities, blended teachers need to be very intentional about how they plan. Check out the video below to see how Jeff plans for instruction in his blended classroom.
A huge benefit to operating in a blended learning setting is the ability to instantly generate data and make decisions based on the outcomes. As the class progresses, I can stay up to date with collaborative assignments on google docs/sheets/slides, while simultaneously checking how students respond to multiple choice questions I’ve assigned through socrative and CFUs embedded in video lessons through eduCanon. When formative assessment is ingrained as part of the learning process, students become more accustomed to feedback and get better at revising work to produce higher-quality finished products. Group interventions also establishes a collaborative environment between students and teacher where both parties are trying to accomplish the same goal - master difficult chemistry content. There’s nothing as powerful as targeted feedback, and in person check ups with each group serve to give students the support they need, exactly when they need it. Having a direct communication avenue between students and teacher enables students who feel unsure about their work to direct questions to me geared at clearing up misconceptions.
By allowing my students to assess other students' work and then providing them with a Student Lab Development Rubric to evaluate their own work, they learn to design and refine high-quality experimental procedures. The Student Lab Development Rubric is one of the tools I use to help students build the experiments they've created and then display results and lab analyses. When students are the ones dictating how they will conduct their experiments, they invest more fully in the activity and come to realize that science involves constant critical analysis and reiteration. I like to move conversations away from "right" and "wrong" and more towards how we can improve each component of our lab activities. Initially, some students feel uncomfortable identifying that their work isn't up to the high standards of the rubric, but over time most come to realize that this process helps them improve their final products and understand the underlying purpose behind labs.
