## Reflection: Complex Tasks Classifying Stars - Section 4: Explore

Improving the End Product

As I looked over the posters at the end of this lesson I realized that students were not able to make adjustments to prior knowledge regarding graphs.  Every graph that we have worked with has shown the numbers at the bottom going from least to greatest.  The graph used in this activity has the temperatures at the bottom going from hottest to coldest.  The transfer and application of knowledge for this activity was too difficult for my students without more modeling.

Although I referred to this same picture when teaching about stars in the beginning of the lesson, this was obviously not enough exposure to help them be successful.  When doing this lesson in the future, I will help them set up their poster stressing how the increments are different than what they are used to.  After they do the research, they will then use the graph on their own to place the stars in the correct location.
