This seminar for the excellence in teaching addresses perhaps the single most important area of student skill development in social sciences and humanities: development of critical thinking and writing skills. This implies a complex teaching and learning process, connected to the development of discipline-based ways of thinking, reading, critiquing and arguing which underlies future development of research and independent learning. Together we will engage in analyzing various discipline-based conceptions of critical thinking, we will critically analyse ways in which critical thinking and writing is taught and we will construct sample students assignments.
