Comments about Including the Science and Engineering Practice
The module explicitly engages students in using 2D molecular representations, 3D interactive molecular models, and interactive simulations to answer questions to illustrate interactions among the components of the cell to make a protein. It should be noted that students do not generate the models but use the models that are provided. The functions of the nucleus and ribosomes are included and illustrated. The module asks students to snapshot/capture their answers to specific questions throughout. This is done for students to show their understanding of the different steps in this process and the relationship between the steps. Students are also asked to answer explicit questions about what they have captured as evidence of their understanding of protein synthesis from the DNA template. A thirteen page teacher guide is included and provides thoughts on possible student misconceptions, discussion questions emphasizing main concepts and extension ideas. An example of a question provided in the teacher guide that expands the information, “Where does transcription take place in an eukaryotic cell? Where does translation take place in a eukaryotic cell? What would be an advantage of this arrangement?" Teachers can combine/modify some of the final questions, so that the questions are asking students to construct explanations of the processes, based on what they learned from analyzing the models throughout the activity. Several of the extension ideas could also be utilized to make this module suitable for an honors or a more advanced high school biology class.
