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.

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.
