Reflection: Rigor How are Mass and Weight Different? - Section 4: Elaborate/Evaluate


When writing a lesson or unit, it's important to keep in mind that you should include complex questions that allow students to think more in depth. I have recently become more familiar with DOK or Depth of Knowledge. The idea behind DOK is that you use it to decide on what kinds of tasks the students will be participating in and what kids of questions you can include to get the students to think more deeply about a concept. Here is a great article that explains DOK.

There are 4 levels of DOK- Level One is Recall, Level 2 is Skill/ Concept, Level 3 is Strategic Thinking and Level 4 is Extended Thinking.  This is a great graphic that lists the different verbs that go with each level.

I also like using these question stems to include in my lessons. In this lesson I used the following questions to  increase rigor and to see if my students were able to answer these more complex questions.

The questions were as follows:

1. How are mass and weight related? (Level 2)

2. Compare and contrast mass and weight.  (Level 2 or 3)

3. What instruments are used to measure mass? Which are used to measure weight? (Level 1)

4. How would you describe the difference between mass and weight to a first or second grader? (Level 3 or 4)

In looking over my students' responses, the majority of them could answer question 3 (Recall), most of the students could also do the comparing and contrasting of mass and weight (level 3) and only a few could describe how mass and weight were related- most were still using the compare and contrast language to describe the relationship. When it came to describing the difference of mass and weigh to a second grader, this was answered well by about half of my students. 

I was not too surprised by the results since my students are really good at recalling information, and can apply skills and concepts, but when it comes to deeper thinking and applying what they have learned, this continues to be challenging for them. They have gotten better at completing more complex tasks but when it comes to verbalizing or writing answers to more complex questions, they continue to struggle slightly. I am not sure if this is part of their language development ( many of my students are ELLs) or that they haven't been given these types of questions and challenges in their previous years.

How are Mass and Weight Different?

Unit 3: Gravity
Lesson 3 of 11

Objective: SWBAT explain what mass is and how it's different from weight.

Big Idea: Knowing the difference between mass and weight is important for understanding how gravity works.
