    the content. (Include titles and authors if possible) Outcomes-Based Teaching & Learning (OBTL) \
    Learning activities aligned with the DLOs (e.g., lectures, discussions, case studies, site \
    visits, etc.) Assessment of Learning Outcomes (ALO)	How will you measure student achievement \
    of the DLOs? (e.g., quizzes, essays, presentations, projects, etc.) Resource Material \
    Supplementary materials to enhance learning (e.g., maps, documentaries, websites, guest \
    speakers) Time Table Suggested allocation of time for each topic/activity within the module. \
    Use only the book {reference_textbook} as reference. Use concise phrasing and commas \
