ANU B.Com ( General) 5th Semester project / Titles / Name / Download / Work Format

Project Work is a learning experience which aims to provide students with the opportunity to synthesise knowledge from various areas of learning, and critically and creatively apply it to real life situations. This process, which enhances students’ knowledge and enables them to acquire skills like collaboration, communication and independent learning, prepares them for lifelong learning and the challenges ahead.

The learning outcomes identify the key areas of learning of the subject. Four learning outcomes are separately articulated: knowledge application, communication, collaboration and independent learning. While students learn to work in groups, they will also learn independently through self-reflection and evaluation of their own work processes. These learning outcomes exist in dynamic interplay rather than as compartmentalized and distinct categories. The following are the learning outcomes for project work:

Domains	Learning Outcomes
Knowledge Application	Students will acquire the ability to make links across different areas of knowledge and to generate, develop and evaluate ideas and information so as to apply these skills to the project task.
Communication	Students will acquire the skills to communicate effectively and to present ideas clearly and coherently to specific audience in both the written and oral forms.
Collaboration	Students will acquire collaborative skills through working in a team to achieve common goals.
Independent Learning	Students will be able to learn on their own, reflect on their learning and take appropriate actions to improve it.
