人類行為的模塑過程，相當複雜，受到生理、心理及社會等因素的影響。社會工作員從事助人的過程，一直稟持著「人在情境中」的信念，相信個體的行為是個體和社會環境互動的結果。因此，社工人員需要一個整合性的認知架構，含括模塑個體行為歷程的共同動態因素，作為其評估（assessment）及處遇（treatment）個人或團體所處的行動脈絡。
本課程將依據一個多元的知識架構來介紹有關人類行為與社會環境的內涵，及生理心理社會架構，並提供一個整合的取向來評估人類的成長歷程及社會生活功能，進而建構一套社會工作實務有關人類行為與社會環境的關係之認知架構。
本課程的目標在協助學生熟悉生理、心理和社會的評估架構。本課程的進行將以課程講授和多媒體教學為主軸，輔以修課學生的小組討論、實例報告、書面作業等教學之方式，學習有關人類行為與社會環境的知識，以及其與社會工作實務之關係。為達成教學目的，學生應事先預習指定作業、出席上課、參與討論、完成指定作業等
Person in situation was the basic tenet of social work practice. Each person is composed of molecules, cell, and organs; each person is also a member of a family, community, culture, nation and world. The two dynamics interact each other to shape a person is what he/she is now. Social work practitioners need a cognitive framework to guide their practice in understanding and assessing human development in social environment.
Using a multi-dimensional framework (bio-psycho-social framework), this course will demonstrate how to assess social functioning of individuals and address the range of issues encounter in the practice of social work. This framework provides a holistic view of human behavior based on applied aspects of conceptual and theoretical materials.
