Characteristics of Feedback that Influence Student Confidence and Performance during Mathematical Modeling

This study focuses on characteristics of written feedback that influence students’ performance and confidence in addressing the mathematical complexity embedded in a Model-Eliciting Activity (MEA). MEAs are authentic mathematical modeling problems that facilitate students’ iterative development of solutions in a realistic context. We analyzed 132 first-year engineering students’ confidence levels and mathematical model scores on aMEA(pre and post feedback), along with teaching assistant feedback given to the students. The findings show several examples of affective and cognitive feedback that students reported that they used to revise their models. Students’ performance and confidence in developing mathematical models can be increased when they are in an environment where they iteratively develop models based on effective feedback

Students’ Perceptions of and Responses to Teaching Assistant and Peer Feedback

Authentic open-ended problems are increasingly appearing in university classrooms at all levels. Formative feedback that leads to learning and improved student work products is a challenge, particularly in large enrollment courses. This is a case study of one first-year engineering student team’s experience with teaching assistant and peer feedback during a series of open-ended mathematical modeling problems called Model-Eliciting Activities. The goal of this study was to gain deep insight into the interactions between students, feedback providers, and written feedback by examining one team’s perceptions of the feedback they received and the changes they made to their solutions based on their feedback. The practical purpose of this work is to begin to make recommendations to improve students’ interactions with written feedback. The data sources consisted of individual student interviews, videos of the team’s meetings to revise their solutions, the team’s iteratively-developed solutions, the team’s documented changes to the their solutions, and the written feedback they received from their teaching assistant and peers. The students explained that helpful peer feedback requires a time commitment, focuses on the mathematical model, and goes beyond praise to prompt change. The students also stated that generic TA feedback was not helpful. The greatest difference between the students’ perceptions of TA and peer feedback was that the TA had influence over the team’s grade and therefore the TA feedback was deemed more important. Feedback strategies to increase peer participation and improve teaching assistant training are described. Suggestions for continued research on feedback are provided

Hosted by Holly Owen.Destroy the Joint is one of the many social media movements that have sprung up in what's been a banner year for sexism. But if such battles are being fought online, do they have an impact offline? Jenna Price, Monica Dux and Dr Anne Summers discuss if Destroy the Joint is creating a lasting legacy, and are they tackling the "right issues"?Jenna Price, Monica Dux and Anne Summershttp://adelaidefestivalofideas.com.au
