DESCRIPTION
This session focuses on studying students' responses. We did the responses of Grade 5 students in using bar models. There are materials for further study involving Grade 3 students doing Singapore Math outside Singapore.

Professional Learning Goal: To engage students in learning
What does it look like when students are
engaged productively in learning?
What are the catalysts to such
productive engagement?

PLC members participated in an open lesson at a
primary school as part of the lesson planning process to get more ideas and insights on student engagement.
Main Task in Research LessonPhoto: Pathlight School
In the lesson planning process, the PLC members came up with a
refined work system to develop and
encourage independent engagement. Photo: Pathlight School
Use coloured paper strips

In the lesson planning process, the PLC members
also decided to use coloured paper strips. During the
lesson, two types of engagement were observed.

Type 1 EngagementSuch engagement is not directly related to content of the lesson. However, students were more involved and were more responsive.
Type 2 EngagementSuch engagement is directly
related to content of the lesson. In this photo a student used the strips to make sense
of the problem situation.
The team was also hopeful that the paper strips would help students connect the diagrams they
draw and the problem situation. Hopefully, students are more engaged when they are doing
things that make sense to them.Photo: Pathlight School

Would the colour help students distinguish the unknown variable from the constant? The purpose of
the research lesson is for teachers to observe students to answer questions such as this one. The
lesson planning meetings raised such questions. The research lesson provides a platform to ‘see’ the
answers to such questions. The post-lesson discussion is a platform to discuss these answers.

While the paper strips were used to help students built the model, they were not used in
helping students do the calculation. In this lesson the
computation was done independently by the
students.
