The Institute of Humanitites and Social Sciences Sciences (IHSS) provides high-quality online undergraduate courses, curricula, and programs for the Global Center for Advanced Studies. As the single Institute of GCAS focused specifically upon undergraduate education, the IHSS performs three vital roles.

  • First, the Institute carries out the mission of making an excellent, affordable, and progressive online education accessible for students, lifelong learners, and professional development worldwide.
  • Second, as an Institute tasked with providing a well-designed, systematic foundation in the disciplines, the IHSS helps to prepare GCAS students for more advanced, graduate-level courses of study provided within all of the other Institutes.
  • Third, the IHSS will progressively develop into an entire undergraduate school, providing a comprehensive, well-designed, fully accredited college education, culminating in degree programs.

About the Program


The first discipline program being developed within the IHSS is Philosophy. A substantive Philosophy curriculum is slated to be offered for the 2023-2016 year, and the first recipients of the GCAS Certificate in Philosophical Studies are projected to complete that program in Spring 2016. Plans are being set in place to build out undergraduate curricula and programs progressively into other disciplines in the Humanities and the Social Sciences during the following years. As central to GCAS’s core mission, ethos, and goals, the discipline of Philosophy will always remain a robust presence within the IHSS.

The outstanding faculty developing courses and teaching students within the Institute are recruited on a number of bases. Devotion to their disciplines and to the art of teaching, demonstrated scholarly work and competence in their fields, passion for promoting learning through innovative pedagogy, years of successful experience inside but also outside of the classroom – all of these are factors in selecting the cadre of educators on the Faculty in the IHSS are provided with professional development opportunities and training, ranging from best practices of online education to intentional course design, from authentic assessment of student learning to high-impact pedagogical strategies. Faculty collaborate across the disciplines to strengthen their own programs, learn from each other, and build a cohesive GCAS educational experience for students worldwide.

Students taking courses in the Institute can expect not only to learn extensively within their discipline, but also to acquire a broad and deep background in the Humanities and Social Sciences, developing competencies needed for 21st century cultural literacy and citizenship. Students progressively develop a body of skills, dispositions, and knowledge generally applicable their lives, communities, and workplaces, with particular emphases upon critical thinking, problem solving, ethics and moral reasoning, written communication, research and information literacy, and information analysis.
