Abstract
Teacher expectations, as literature in psychology has shown, can matter for a student’s performance by creating self-fulfilling prophecies, which is known as the Pygmalion Effect (Rosenthal & Jacobson, 1968, 1992). Using an experimental design, we aim to shed light on answering whether this hypothesized effect of teacher expectations can be harnessed to improve student effort, achievement and engagement, in a low-resource context, like Pakistan. As part of our treatment, teachers deliver statements conveying high expectations of effort to students. Using an experimental design, our study aims to shed light on whether: (a) expectations of high effort and achievement affect student performance and engagement; (b) the treatment effect differs according to whether these expectations are conveyed to a student individually or in a pair and (c) the treatment effect differs by gender. We will also analyze how the intervention affects student peer interactions.

Experimental Details

Interventions

Intervention(s)
Using an experimental design, we aim to answer whether high teacher expectations can be used to improve student effort, cognitive and non-cognitive outcomes, parental engagement, and teacher engagement.

Primary Outcomes

Primary Outcomes (end points)
Our main student-level outcomes include self-efficacy, self-esteem, motivation and effort, student stress levels, growth mindset attitudes, and academic performance. Our main class-level outcomes include attendance, engagement, punishments/warnings, classroom behavior.
Primary Outcomes (explanation)

Secondary Outcomes

Secondary Outcomes (end points)
We intend to additionally measure the following teacher-level outcomes: expectations, engagement, and perceived interest in child's education. Our parental-level outcomes include engagement, investment in child's education and beliefs.
Secondary Outcomes (explanation)

Experimental Design

Experimental Design
We divided ~320 classrooms in our study into three groups: (1) Control Group (status quo) (2) Individual Treatment Arm, where student-specific high teacher expectations and encouragement were conveyed individually and (3) Peer Treatment Arm, where student-specific high teacher expectations and encouragement were conveyed to a student and in addition, they were randomly matched with another classmate (of same gender) and were encouraged to work together.
Experimental Design Details

Randomization Method
Cluster Randomization (using STATA)
Randomization Unit
Classrooms at the first stage of randomization (i.e. dividing our sample into control and treatment group). In our treatment arms, we further use within classroom randomization at the second stage.
Was the treatment clustered?
Yes
