## Reflection: Continuous Assessment Dunking for Density Investigation (Part 2/2) - Section 3: Explain/Evaluate

Continuous assessment is the teaching practice that assumes that we, as teachers, are always observing our students in order to collect little bits of information that help us form a picture of what students understand. In busy, full classrooms, sometimes it is difficult to collect this information, in a complete way, on the fly through interviews, student questioning, discussion, student interaction or eavesdropping.

For this reason, I find it beneficial to use the MAMM strategy (Multiple Assessments Using Multiple Modalities). This strategy requires more advanced planning, but results in a more accurate picture of what students know and can do. With regard to the concept of density, between the Dunking for Density Investigation and the associated basic density lesson, Measurement: Density, students not only experience the concept in a variety of ways, they are also assessed in a variety of ways. The written assessment is the RECALL Final Lab Conclusion. For visual learners, students are assessed through their Dunking for Density Final Project. For assessment of basic understanding, students take a basic multiple choice quiz. All along the way, I still collect those little tidbits by listening to students. The final goal is to decipher the trajectory of student understanding in order to move students closer to the learning objective.
