Title:The potential of a classroom network to support teacherfeedback: a study in statistics education
In mathematics education teachers experience a constant lack of timeto properly instruct their students. In the Netherlands the contacttime for mathematics in secondary education during the last fifteenyears again declined. Mathematics is also perceived as difficult bystudents. This research focuses on the question: how can we betterutilize 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 toolsfor improving learning achievements. In this study we explore thepossibility of graphing calculators (GR), connected to the teachercomputer through the use of a wireless network, to improve thefeedback in mathematics education. First, students received immediatefeedback on their worked out mathematics assignments GR and second,the teacher, usually in the next lesson, gave feedback on the work ofthe students, supported by an analysis of that work through thesystem. This study focused primarily on the development of 'dataliteracy' among students, while the 'algorithmic skills' were notforgotten.In four stages, a prototype of the intervention designed, tested,evaluated and adjusted in nine groups of students. The mathematicsteachers and their students are generally enthusiastic about theresults. They for instance recommend to spend half of each lessonworking this way. Though, the teachers explicitly state that they haveexperienced a tough workload while mastering this way of teaching. Thestudy makes the conditions to be met before the method can besuccessful explicit.
