Week 1 Memo- Joey Tedeschi
The NGSS Framework reading focused on the importance of students engaging in scientific inquiry by using knowledge and skill together. The chapter explains why learning science and engineering practices is important for students and which practices are essential through K-12. Asking questions (for science) and defining problems (for engineering), developing and using models, planning and carrying out investigations, analyzing and interpreting data, using mathematics and computational thinking, constructing explanations (for science) and designing solutions (for engineering), engaging in argument from evidence, and finally obtaining, evaluating and communicating information are the practices mentioned. The chapter then discusses the similarities and differences between science and engineering practices. The importance of each practice is explained, and then tied back to the importance of students exploring how science is done in the real world and how these communities communicate. The hope is students will not only become more knowledgeable in content and skills, but will also be more critical consumers of scientific knowledge.
The second reading by Schwarz et al. was a research article that explored scientific modeling and how one might develop a learning progression to make modeling accessible and meaningful for learners. The article mentions two dimensions, the first being metaknowledge and the second being elements of practice. Basically, the authors want students to not only construct, use, evaluate, and revise scientific models, but also understand the nature and purpose of models. The article then presented and explained the research they conducted for elementary and middle school students. They found that students were able to use models to make predictions, evaluate and compare important aspects of models for a consensus model, and they were able to revise models to accommodate for new information. The article then discussed some of the challenges that arise when modeling in the classroom.
It is so easy to accept information from a media source and blindly accept what we were told. Engaging in practices creates good habits for students such as asking questions, communicating and understanding science. I think that models are never done being revised because learners are engaging in the models differently, unique to their perspective. Models can always be revised to help a learner gain a better understanding of the theory or knowledge. Teachers should be cautious telling students when to revise their models. Rather, the teacher should guide a class discussion about why a model should or should not be revised. Students should construct their knowledge as a whole, bringing value to their ideas.
