Argumentation as a Strategy for Conceptual Learning of Dynamics

Researchers have emphasized the importance of promoting argumentation in science classrooms for various reasons. However, the study of argumentation is still a young field and more research needs to be carried out on the tools and pedagogical strategies that can assist teachers and students in both the construction and evaluation of scientific arguments. Thus, the aim of this study was to evaluate the impact of argumentation on students’ conceptual learning in dynamics. True-experimental design using quantitative research methods was carried out for the study. The participants of the study were tenth graders studying in two classes in an urban all-girls school. There were 26 female students in each class. Five argumentations promoted in the different contexts were embedded through the dynamics unit over a 10-week duration. The study concludes that engaging in the argumentative process that involves making claims, using data to support these claims, warranting the claims with scientific evidence, and using backings, rebuttals, and qualifiers to further support the reasoning, reinforces students’ understanding of science, and promotes conceptual change. The results suggest that argumentation should be employed during instruction as a way to enable conceptual learning.     

A study of in-service teacher educator roles,with implications for a curriculum for their professional development

In-service educators have a crucial role to play in meeting the professional learning needs of teachers of the future, according to the Council of Europe’s ‘ET 2020’, although it is less clear what that role entails. This empirical study, undertaken in a university school of English language in Turkey, explores the everyday experience of a team of wholly school-based in-service educators and develops a model of their role based on an analysis of questionnaire, interview and focus group data. The results attest to the complexities of the in-service educator’s role, revealing them to be more than simply effective teachers. Catering for affective needs, coaching a broad range of clients, interpreting contextual variables and providing appropriate feedback represent some of the challenges in-service educators are facing in the research context, which set them apart and suggest important lessons for the development of an in-service educator training curriculum.

EXAMINATION OF THE RELATIONSHIP BETWEEN ENGAGEMENT IN SCIENTIFIC ARGUMENTATION AND CONCEPTUAL KNOWLEDGE

Whereas there are some studies presenting the effects of argumentation on science knowledge development, there is still a need for research discovering the interrelationship between knowledge and argumentation. The purpose of this research was to investigate a possible relationship between students?? engagement in argumentation and their conceptual knowledge. A case study design was carried out for this research. The participants of the study were tenth graders studying in an urban all-girls school. There were 5 argumentations promoted in different contexts which were embedded through the dynamics chapter, for a 10-week period. Some of the conclusions drawn from the study are as follows: First, students?? quantity and quality of arguments improve through time as they get more involved with argumentation. Second, students?? knowledge does not improve instantly when they are involved with argumentation activities, that is, knowledge development in an argumentation process takes time. Third, students?? prior knowledge affects their participation in argumentation. Last, there are some patterns that indicate the relationship between argumentation and knowledge. However, students?? arguments and their knowledge do not develop at the same time.
