In mathematics education teachers experience a constant lack of time to properly instruct their students. In the Netherlands the contact time for mathematics in secondary education during the last fifteen years again declined. Mathematics is also perceived as difficult by students. This research focuses on the question: how can we better utilize contact time in mathematics education?
Meta-analyses of learning outcomes, such as those described by Hattie (2009), show that feedback is one of the most powerful single tools for improving learning achievements. In this study we explore the possibility of graphing calculators (GR), connected to the teacher computer through the use of a wireless network, to improve the feedback in mathematics education. First, students received immediate feedback on their worked out mathematics assignments GR and second, the teacher, usually in the next lesson, gave feedback on the work of the students, supported by an analysis of that work through the system. This study focused primarily on the development of 'data literacy' among students, while the 'algorithmic skills' were not forgotten.
In four stages, a prototype of the intervention designed, tested, evaluated and adjusted in nine groups of students. The mathematics teachers and their students are generally enthusiastic about the results. They for instance recommend to spend half of each lesson working this way. Though, the teachers explicitly state that they have experienced a tough workload while mastering this way of teaching. The study makes the conditions to be met before the method can be successful explicit.

Molecular hydrogen (H2) makes up 99% of the cold dense gas in galaxies. So mapping where stars are born basically means measuring H2, which lacks a strong characteristic signature at low temperatures. Astronomers from SRON Netherlands Institute for...
