Which DOK would you select to describe the activity of performing a science experiment on the melting rate of solids?

• A. Basic Recall
• B. Strategic Thinking/Reasoning
• C. Engagement
• D. Integration of Knowledge

Answer: (B)

The activity of performing a science experiment on the melting rate of solids is best described as an example of Strategic Thinking/Reasoning. This level of Depth of Knowledge (DOK) emphasizes the application of knowledge to solve problems and make strategic decisions. Conducting an experiment involves planning, hypothesizing, observing, and analyzing the data collected from the experiment, which are all higher-order thinking skills.

In this context, the learner is not simply recalling facts or basic information about the melting process; they are actively engaging in a scientific inquiry that requires reasoning and critical thinking to draw conclusions from the results of the experiment. This kind of activity necessitates an understanding of scientific principles as well as the ability to analyze and interpret results, which is a fundamental aspect of Strategic Thinking/Reasoning.

Other choices, such as Basic Recall, refer to fundamental memorization of facts without deeper cognitive engagement. Engagement implies participation but does not necessarily encapsulate the reasoning and strategic thinking involved in formulating hypotheses and interpreting experimental outcomes. Integration of Knowledge might suggest a synthesis of different information but falls short of the specific application and problem-solving focus that the experiment demands. Thus, Strategic Thinking/Reasoning is the most appropriate descriptor for this activity.
