Students will be creating a final summative assessment of their understanding of the metric tools and units used in Science. They will be using what they learned in all of their formative assessments, as well as any notes and lab activities completed in class. Here's a link to the main formative assessments that students can use while completing this summative assessment.
Students will be verbally explaining what the tools are used to measure, how they may be different from each other, and the units used with each tool. They have the freedom to incorporate video, photos they take or find (must be cited) that can be annotated over, and any other tool they feel will help them in completing the assignment. The only restriction I am placing on the actual assignment itself is the tools they must include and that it has to have their voice verbally explaining (and not reading) what they have included in their "presentation." Students must use Explain Everything as the tool to complete the assignment. Here is a description of the assignment I would give to my students.
Strand: The Nature of Science and EngineeringCode: 22.214.171.124.2, Benchmark: Determine and use appropriate safety procedures, tools, measurements, graphs, and mathematical analyses to describe and investigate natural and designed systems in Earth and physical science contexts.
The metric system is something that students use throughout all of their science courses. Students continue to struggle with how to properly use the tools and understand what they are used to measure. It seems that the activities and basic assignments we have incorporated into our curriculum is perhaps not enough. Thus, I've created more deliberate formative assessments and a larger summative assessment.
I have found that with the addition of 1:1 iPads in my classroom my favorite part of having students use this tool is the fact that they can verbally explain their learning. I have found that this is a fantastic way to truly see what students know and understand about a topic. Some students struggle with writing down what they know, through any form of writing - short answer, a test/quiz, or just a written paragraph/journal. When students are asked to verbally explain what they know, they can give me SO much more! I think there's just something about the freedom of just speaking and letting your ideas come out - it's often so much easier (& even causes less anxiety) for most students. I have not yet assigned this assessment to my students, but I do plan to use it next year.
