Chemistry Hunger Games
Synthesizing a year's worth of content is difficult for any student, so I always look for innovative new ways to keep my students engaged attempt to conquer all of the learning objectives in chemistry. During the 3 weeks leading up to the final exam, my classroom temporarily turns into a Chemistry Hunger Games war zone where students battle to "kill" off districts - each representing a different unit from the year. Using the chemistryhungergames.com website I designed, my students pour over videos, screencasts, text, images, simulators, and practice problems that prepare them for district assessments. Each student is allowed to take the district assessment as many times as needed to master the district’s content, and I rotate enough questions to make about 5 assessment versions for each district. Point values are assigned according to the proficiency level they achieve on their assessments - all of which are tracked online using a conditionally formatted google sheet to help monitor progress. This gamified twist to the learning process keeps students focused on the ultimate task, mastery of content, while also helping to reinforce that with enough practice and guidance, they have the ability to master anything.
My first college lab report really humbled me when it was handed back covered in red ink – my professor was asking for a lot of revisions. However, this feedback was crucial to my development as a scientist, and I want to expose my students to the feedback and revision loops I experienced before they had off to more advanced schooling. Students learn to give and receive feedback during the Critical Friends review period that occurs at the end of big labs. At this stage in the class each group presents their lab results to another group using Wikispaces digital portfolios, and then makes an argument as to how their results answer the lab’s guiding question. Classmates then offer targeted feedback during the Wreck-It portion of Critical Friends, before each group reconvenes to make necessary edits to their work. Students love when they get to play devil’s advocate and present critical “wreck-it” counter-points to other groups' arguments. It’s important to remind students to also offer advice on how to improve the other groups’ portfolio and help them build a more cohesive argument. Each group then reconvenes and makes the necessary edits to their work. Adding more critical eyes to student work makes my job as a teacher more manageable, and guarantees improved overall lab report quality. My goal is that by the time my students take college chemistry or organic chemistry, they will have already had experience assessing the validity of lab analyses and improving experimental design, data collection, and other crucial lab components.
I’ve been interested in the power of checklists ever since I read Atul Gawande’s Checklist Manifesto. His book highlights how simple checklists have revolutionized industries like architecture, aviation, and surgery. When students are regulating their own work pace, I offer them structure in the form of Mastery Checklists that provide guidance around individualized learning paths. Students start each day by looking at data from previous assessments, and adjusting action plans with learning goals for the day. Then they work through their checklists and update their Trello boards with finished work samples. By pairing Mastery Checklists with a visual organization tool like Trello, it’s easy for me to keep my finger on the pulse of each student’s activity, and guide them in the right direction.
10 years ago, great teachers would hastily grade free-response questions overnight in an effort to provide feedback to students in a timely manner. However, the days of using data as taillights are behind us. Tools like Educanon, Formative, and Google Docs make it easy to collect actionable data and make informed, instantaneous decisions around dynamic grouping, individual competencies, and even customized learning paths. For example, Formative allows me to upload a document, designate areas for student input (multiple choice, free response, and even drawing), and then assign the activity to students. As students fill in the doc at their own pace, the teacher interface is updated in real-time so that I know which students need my help and when. I can pair struggling students with those who are just figuring it out, gather students for small group instruction, or re-teach concepts when there is a trend of misconceptions. Beyond that, catching student miscues as they happen makes it easier for me to help students polish unfinished work, fill in gaps in knowledge before summative assessments, and learn how to correct their own mistakes.
