Dr. Md Saidul Islam has taught at four universities across two continents: York University in Canada, the College of William & Mary in the United States, Nanyang Technological University in Singapore, and Nankai University in China, delivering a wide range of courses related to development, environment, and sustainability. He has developed and taught core, elective, general education (GER), and postgraduate courses, and has supervised four PhD students. His recent Student Feedback on Teaching (SFT) scores have consistently exceeded both School and Faculty averages.

In 2014, he was nominated for the Nanyang Education Award by the Division of Sociology. Dr. Islam holds a Certificate in Teaching for Higher Education (Part 1) from the Centre for Educational Development at Singapore's National Institute of Education, a 50-hour intensive program. Demonstrating pedagogical innovation, he has produced an edited volume and submitted a grant proposal focused on sustainability education. He has also been invited to conduct teacher training workshops in Singapore, Malaysia, Turkey, Bangladesh, and other countries.

Dr. Md Saidul Islam's teaching philosophy centers on encouraging students to become critical readers, thinkers, and writers. His goal is not only to promote deep intellectual engagement with a diverse range of texts but also to help students become more discerning readers and persuasive writers in understanding and analyzing the world around them. To achieve this, he applies the following 5 core pedagogical tools for teaching:

Over the past 15 years, Dr. Md Saidul Islam has taught both Sociology and interdisciplinary courses at four globally recognized universities: York University in Canada, home to one of the country's largest Sociology programs; the College of William and Mary in the United States, ranked among the top six public universities and the second oldest after Harvard; Nanyang Technological University (NTU) in Singapore, ranked 13th globally by QS; and Nankai University in China, one of the nation's top ten public universities.

Dr. Islam has independently developed all the courses he teaches. When he joined NTU in 2009, the Division of Sociology was in its formative stage. He played a pivotal role in its growth by designing and introducing key undergraduate courses such as Environmental Sociology, Economy and Society, and Development and Social Change, helping transform the division into a more mature and comprehensive program. As NTU increasingly prioritized sustainability, he responded by creating a general education requirement (GER) course titled Environmental Sustainability, as well as a new seminar course, Cultural Politics of Development and the Environment. At the graduate level, he also developed and taught courses such as Global Sociology and Globalization and Sustainability.

Dr. Md Saidul Islam's teaching history is as follows:
