Abstract
Economic studies often use years of schooling or average enrolment rates as measures of education, even though these readily available measures tend to be very noisy and aggregate a variety of distinct elements. However, recently, the focus has shifted towards the direct measurement of cognitive skills – one of the main skills that we aim to teach students in school and university (Finn et al. 2014; Hanushek and Woessman 2008).

Our research project aims to tackle these aforementioned problems in a Randomized Controlled Trial (RCT). First, we plan to induce random variation in improvements to cognitive and non-cognitive skills by teaching a specifically designed course to university students as part of their education. Our focus will be how academic outcomes are affected by this intervention. We plan to offer undergraduate students a mandatory semester-long course to improve their cognitive skills. We will randomly assign students to one of three experimental groups: (i) a treatment group receiving a cognitive (analytical) skills course, (ii) a second treatment group receiving a non-cognitive (soft) skills course, and (iii) a pure control group. We will measure academic outcomes using surveys, administrative academic data and lab-in-the-field experiments.

Interventions

Intervention(s)
We are teaching one course in cognitive skills (one third each from economics, psychology and philosophy) and one in non-cognitive skills. The students are randomized into groups.

Experimental Design

Experimental Design
We will randomly assign students to one of three experimental groups: (i) a treatment group receiving a cognitive (analytical) skills course, (ii) a second treatment group receiving a non-cognitive (soft) skills course, and (iii) a pure control group.
Experimental Design Details
Randomization Method
Eligible students were randomly allocated to either one of our courses or the control group. The randomization was done with the "randtreat" Command in Stata based on a list of eligible students supplied by our partner university.

Experiment Characteristics

Sample size: planned number of clusters
No clusters
Sample size: planned number of observations
300 in first round, more later (uncertain because it depends on university enrollment)
Sample size (or number of clusters) by treatment arms
Equally divided between the groups with only small differences due to logistical issues
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
Based on a minimum sample of 750 students assigned to two treatment arms and one control group equally (250 students per group), the minimum detectable effect size is 0.2511 (for a 20% Type II error probability, i.e. beta = 0.2). The enumeration of 750 students is our planned minimum and depends on various local factors. We therefore hope to enumerate more than the minimum of 750 students, the effect size of 0.2511 hence constitutes our most conservative estimate.
