Synopsis

This POGIL activity is intended as an in-class activity for a CS 1 course (Java), potentially replacing a lecture, lab, or recitation section. The activity introduces students to the Java operators % and /, and the difference between integer and floating-point division. It also introduces students to the POGIL roles and requires students to reflect on their collaboration.  This activity may be given on the first day of class in CS 1 (no Java experience necessary).

Model 1 was authored by Mark Morehouse; Models 2, 3 and 4 was authored by Helen Hu.

Recommendations

Students should be assigned in groups of 3-4 students (ideally four students). The instructor should provide POGIL role cards

While this written activity only takes 60 minutes, it's important to allow time (an additional 20-30 minutes) for student groups to report out their answers and to facilitate discussion. The activity may be broken into two separate activities (Models 1-2 in one class period, Models 3-4 in a second class period) if necessary. 

Learning objectives for POGIL activities are divided into content learning objectives (CS concepts) and process learning objectives. After completing this activity, learners should be able to:

Content Learning Objectives:

•   Evaluate a Java expression that uses the % operator with integers.

•   Evaluate a Java expression that uses the / operator with integers.

•   Explain the difference between integer and floating-point division.

Process Learning Objectives:

•   Explain the responsibilities of the POGIL roles.

•   Provide feedback on how well group members are fulfilling their responsibilities.

Engagement Highlights

POGIL (Process Oriented Guided Inquiry Learning) is a research-based instructional strategy shown to increase pass rates and student retention of course content. Students are assigned roles (see role cards) that provide guidance on working together effectively. Instead of lecturing, instructors work as facilitators of learning, which encourages equity in the classroom. POGIL activities are completed during class (not as homework). They can replace a lecture, lab, or recitation class.

POGIL activities are designed to guide students through a Learning Cycle of Exploration, Concept Invention and Application. Students will explore information directly presented in the model, use this information to develop a new idea or better understanding of a concept, and finally apply this information in a new context.
