As school districts across the country approach the implementation of the Next Generation Science Standards, students will be required to develop models to illustrate what occurs at an atomic level as well as apply various mathematical representations in order to explain a science-based concept. However, what opportunities are we providing our students to allow them to explain what they know about a concept? Students should be provided with regular opportunities to develop and explain concepts, which in turn will allow teachers to formatively assess and address misconceptions.
Last Thursday (11/6/14) I attended a workshop on NGSS through our local RESA (essentially an ISD for the county/region). I’d like to touch on some of the things I took away from this workshop and will post again after the next follow-up workshops in December and March.
At NSTA (in beautiful San Antonio, Texas), this past week, I shared activities designed to explore three levels of representation AND provide formative assessment techniques to reveal student misconceptions. All of the activities shared have been featured in the Journal of Chemical Education or have been linked to research articles in JCE as supporting information.
