Reflection: Rigor Pumice vs Obsidian - Section 3: Conclusion

 

Writing a conclusion can be challenging for students. The writing tied to including evidence brings rigor to the learning experience. Rigor means academically, intellectually, and/or personally challenging. A rigorous learning experience helps students to understand complex concepts and acquire skills that meet the College and Career Readiness Standards. Rigor encourages students to question assumptions and think deeply.

When my students write a conclusion, I encourage them to use the sentence frame I learned that . . .because . . . I have seen great student growth in writing and thinking this year as students use sentence frames and include evidence with their thinking. Here is what some students wrote:

I learned that the two rocks are very different with one similarity because they have different color, density, weight, texture, and luster, but they are both igneous rocks.

I learned that even though some rocks are formed that same way, they aren't going to be the same because pumice and obsidian are almost nothing alike.

I learned that pumice and obsidian are different and the same because they are both made by magma but they have different features.
