Understanding graphs in the dynamics of market (DM) is a challenge to learners; its teaching demands a specific kind of teacher’s knowledge. This study aims to examine the topic-specific pedagogical content knowledge (TSPCK) of experienced economics teachers in teaching graphs in DM to enhance learners’ understanding of the topic. It reports using a qualitative approach underpinned by the TSPCK framework for teaching specific topics developed by Mavhunga. Data were collected through classroom observations and analyzed thematically using a case study of two economics teachers. The study revealed that adopting a step-by-step approach and the use of worked graphical examples promote an understanding of graphs in DM. It also established that active learning is preferable to the predominant chalk-and-talk (lecture) method of teaching graphs in DM. The study proposed a Dynamics of Market Graphical Framework (DMG-Framework) to enable teachers, particularly pre-service teachers in lesson delivery, to enhance learners’ understanding of graphs in DM. The result of this study will broaden the international view in the teaching of graphs in DM.

This article describes a methodology and a didactic innovation in higher education that employs Collaborative Online International Learning (COIL) across four universities in the fields of sociology, psychology, social education and economics in order to explore the phenomenon of economic violence. The COIL activities were developed by four teachers in the second semester of 2022. The students explored the social and cultural origins of economic violence and the daily exposure to economic inequality in the domestic sphere, while also studying the prevention and responses offered by anti-violence centers from both organizational and social perspectives. The most novel aspect of COIL projects is the research approach to the topic (gender violence) and the students' participation in extracurricular activities, namely presenting the results of their research developed during their academic subjects after the course, at international events. In this study, we describe the projects and the assessment of this part of the research, analyzing the perceptions of the Italian and Spanish students who participated in the dissemination activity. The students' perceptions were recorded through a semi-structured questionnaire utilizing Likert scales and open-ended questions, which included their self-assessments of their knowledge before and after participating in the project, the impact on their development of competences and skills, and their satisfaction with the whole experience. Students acquired a great deal of knowledge and understanding of the phenomenon being studied through COIL methodology and connected these extracurricular activities to a clear improvement in their transversal skills.
