Many educational interventions encourage parents to engage in their child’s education as if parental time and attention is limitless. Sadly, though, it is not. Successfully encouraging certain parental investments may crowd out other productive behaviors. A randomized field experiment (N = 2,212) assessed the impact of an intervention in which parents of middle and high school students received multiple text messages per week encouraging them to ask their children specific questions tied to their science curriculum. The intervention increased parent-child at-home conversations about science but did not detectably impact science test scores. At the same time, the intervention decreased parent engagement in other, potentially productive, behaviors, such as turning off the television or monitoring their child’s studying. These findings illustrate that parent engagement interventions are not costless: there are opportunity costs to shifting parental effort.
This paper reports improvements in teacher job performance, as measured by student test scores, resulting from a program of (zero-) low-stakes peer evaluation. Teachers working at the same school observed and scored each other’s teaching. Students in randomly-assigned treatment schools scored 0.07σ higher on math and English exams (0.09σ lower-bound on TOT). Within each treatment school, teachers were further randomly assigned to roles: observer and observee. Teachers in both roles improved, perhaps slightly more for observers. The typical treatment school completed 2-3 observations per observee teacher. Variation in observations was generated partly by randomly assigning a low and high (2*low) dose of suggested number of observations. Benefits were quite similar across dose conditions.
