Interdisciplinary curricula provide students the opportunity to work with knowledge drawn from multiple disciplines. Following suit, interdisciplinary learning requires interaction of knowledge from different disciplines; integration of knowledge from different disciplines; and an overarching topic, theme, or problem that shapes the learning experience. Since the university curriculum is commonly structured by academic disciplines, and faculty are socialized to their respective disciplinary norms, interdisciplinarity is a complex endeavor for colleges and universities. These endeavors include developing interdisciplinary courses, sustaining interdisciplinary initiatives, and financing interdisciplinary programs.
Given the multiple challenges facing 21st-century society, the question of interdisciplinarity is urgent. How knowledge is defined and disseminated; how and what students learn; and how higher education can be responsive to its external environment are crucial issues facing educators. Responding to these issues does not diminish the role of the discipline in education, but rather acknowledges that knowledge is unbounded and potential discoveries lie outside compartmentalized structures.
Lesson Study is a form of collaborative, classroom-based teacher professional development, and also a form of institutional and local educational system improvement. It originated in Japan and experienced rapid global spread in the 21st century. The deliberate processes of Lesson Study can help overcome specific factors that can form barriers to teacher professional learning—factors such as the complex environment of the classroom and the role of tacit knowledge.
