Learning Trajectories questions

1. What are the two components of learning progressions?



2. What are learning progressions used for in instructional design or implementation?





3. In the example with the puddles, what are the two different pieces of knowledge that students could have learned from the experiment (based on people raising the questions)?




4. What factors influenced the order in which they were learned (the fact that students explored and attempted to answer one of the anomalies and not the other)?




5. What aspect of how learning progressions are typically laid out are
the authors trying to argue against with their puddle example?








6. Spiral curricula hinge on what statement about presenting concepts 
to young children?







7. What are the three key attributes of a spiral curriculum?








8. What are the two advantages of spiral curricula?





9. In the absence of empirical evidence for orderings between learning
goals, what heuristics did the LTEC use to order LGs?






10. In what way did mathematics instruction influence the order of 
topics in sequence?







11. In what way did the language used (Scratch) influence the order of 
topics?
