Investigating the impact of automated feedback on students’ scientific argumentation

ABSTRACT

This study investigates the role of automated scoring and feedback in supporting students’ construction of written scientific arguments while learning about factors that affect climate change in the classroom. The automated scoring and feedback technology was integrated into an online module. Students’ written scientific argumentation occurred when they responded to structured argumentation prompts. After submitting the open-ended responses, students received scores generated by a scoring engine and written feedback associated with the scores in real-time. Using the log data that recorded argumentation scores as well as argument submission and revisions activities, we answer three research questions. First, how students behaved after receiving the feedback; second, whether and how students’ revisions improved their argumentation scores; and third, did item difficulties shift with the availability of the automated feedback. Results showed that the majority of students (77%) made revisions after receiving the feedback, and students with higher initial scores were more likely to revise their responses. Students who revised had significantly higher final scores than those who did not, and each revision was associated with an average increase of 0.55 on the final scores. Analysis on item difficulty shifts showed that written scientific argumentation became easier after students used the automated feedback.     

Constructivism as a framework for literacy teacher education courses: the cases of six literacy teacher educators

This paper presents findings from the large-scale study Literacy Teacher Educators: Their Backgrounds, Visions, and Practices that includes 28 literacy/English teacher educators (LTEs) from four countries. The participants were interviewed three times and shared their course outlines. Six pre-service LTEs who use a constructivist approach are presented. The six LTEs speak English as their mother tongue. Three aspects of constructivism are discussed: knowledge is constructed by learners; knowledge is experience based; and a strong class community is essential. They have adopted a constructivist approach because they conceptualised the teaching/learning process as a partnership. Constructivism is a flexible and fluid framework so individual LTEs can shape their work for their context and draw on their strengths; however, it is demanding because courses have to be somewhat organic in order to create space for discussion of issues as they arise.
