Working with Next Generation Science Standards 1. Focus on fewer big ideas building over time Japanese eighth-grade textbooks cover eight topics, compared to an average of more than 65 for U.S. eighth- grade textbooks.” (Linn, Lewis, Tsuchida, Songer, 2000) 2. Emphasize science practices e.g., explanations, predictions, data collection, modeling 3. Systematic guidance in developing content + science practices
3
What We Do Build tools + curricular units emphasizing guided development of explanations around focal content 4, 5, 6 th grade biology/ecology (8 weeks) 8th grade, high school Climate Change (8-14 weeks)
5
Fusing Content + Practices Content Ecology 13: Because many animals rely on each other, a change in the number of one species can affect different members of the web. Science Practice Explanations: Students build a complete scientific explanation consisting of a claim, two pieces of Evidence and Reasoning with content hints Learning goal: Students construct scientific explanations to address the question, how have recent changes in the Detroit River affected yellow perch populations?

Systematic Guidance of Strategic Thinking

26% of fourth graders have difficulty generating two pieces of evidence for an explanation, even with guidance26% of fourth graders have difficulty generating two pieces of evidence for an explanation, even with guidance (Songer and Gotwals, 2012)(Songer and Gotwals, 2012)
