Project management tuition or training, can we assess the added value of them?

From the article: "Various programs in higher education feel a need to teach project management skills to students. Measuring the effect of education is a challenge especially when focused on behavioral skills. Research on learning gains usually turns to the method of Students Assessment of Learning Gains (SALG), which can be questioned on reliability. This article constructs five design criteria for an improved Students Assessment of Learning Gains (SALG): measure satisfaction, use pre- and posttests, use perceived ability, account for learning stage one and account for attrition. A first test on a semester of a professional master in project management yields ambiguous results. The second test with a 360 degrees measurement is performed on the same semester with different students. The post test is scheduled for June 2014, results will be reported at the World Congress.
