Abstract:
The purpose of this study is to examine the impact of action research to improvestudents' abilities for word problem solving. The cooperation between a third grade teacher (Rajmonda) and a professor from the university focused on examining the results of the implementation of the two activities within the action plans, 'Developing the mathematical vocabulary' and 'Formative assessment- feedback'. Thus the project reviewing the impact of 'activities' in the process of word problem solving can be seen as 'under-study' within the broader study of the effect of collaboration in action research. From the analysis of qualitative data (interviews with students, observation and journal entries) and quantitative(questionnaires and tests) seen a significant improvement of the results of students inword problem solving. Developing mathematical vocabulary enabled them to understand mathematical terms and requirements while providing feedback problems led to the improvement of the 'gap' in the process of problem solving.
