Reflection: Coherence Proteins in the Brain, Body and Nutrition: A Neurological Trifecta! (Day 2 of 2) - Section 3: Extend


          The practice of making claims in the science classroom is a powerful strategy that could stimulate students to think scientifically in and out of the classroom. Though a powerful and mentally catapulting process, claim creation and providing support thereof can prove stressful for students if they are not comfortable at this level of thinking. One of my strategies to minimize this potential stress for students, especially within lessons that have many moving parts or activities like this one is to direct students to distill and organize the major take always from the activities (revising claims, listing evidences, and extracting significant items on an index card). See student work attached. In this part of the lesson, students are simulating the movement of alleles, performing statistical analysis and simulating the electrophoresis process in the effort to understand the genetic basis of PKU.  When they are guided to extract meaning from their labors and collate it onto one place, they have to assess what counts. Once assessed, students can produce a "flashcard" of sorts that creates continuity from lesson to lesson (revisiting and supporting claims) and activity to activity (allele assessment and gel electrophoresis). This, in turn can make it easier for students to visualize and provide continuity for the core idea(s) hidden in a variety of activities and ultimately make students more comfortable with making and supporting claims.
