PolyU's PALMS project, the UGC teaching and learning project for Pedagogic & Active Learning Mobile Solutions, supports conceiving, designing and creating active teaching methods and their corresponding mobile solutions in STEM (science, technology, engineering and mathematics) related education. Our objectives are to (i) increase students' overall learning outcomes through active learning, e.g., conceptual understanding, motivation, collaboration, academic performance and lifelong learning; (ii) explore and develop active learning pedagogies to increase student engagement in STEM higher education; (iii) develop an online platform to promote and encourage wider adoption of active learning among Hong Kong STEM instructors; (iv) use and improve quantitatively rigorous and valid methods to evaluate the impact of active learning strategies on student learning outcomes in STEM education; and (v) adapt existing or develop new mobile applications to enhance active learning.
