Learn, Apply, and Build 21st Century Skills (Lab21) is a sixth-grade course in which students use the principles of science, technology, engineering, and math (STEM) in real-world contexts to solve problems. Students also create meaningful digital content to communicate thinking and ideas to broader audiences. The course starts out with a unit on growth mindset where learners explore how the brain works and how thoughts, feelings, and actions both positive and negative directly impact people. Next, students learn about computational thinking practices. Computational thinking is a problem-solving process that is made up of several dispositions: logically ordering and using data, using algorithms (ordered steps) to solve problems, dealing with complexity, and deal with open-ended problems. Computational thinkers look for and recognize patterns across disciplines allowing them to make connections between learning content and the world around us.
