Description
This subject is a foundation for later-stage subjects. In this subject students learn about: electrostatics, circuits, magnetism, electromagnetism and induction, waves, physical optics, introductory atomic physics and quantum theory. Research linked to each of the topic areas, and which is happening within the School of Mathematics and Physical Sciences at UTS, is integrated into this subject.
Subject learning objectives (SLOs)
Upon successful completion of this subject students should be able to:
| 1. | recognise the principles and laws of physics most relevant to current and future studies in the physical sciences. |
|---|---|
| 2. | master and apply physics concepts to a range of problems in the physical sciences |
| 3. | effectively communicate experimental design, methods, findings and conclusions through semi-formal oral presentations in a laboratory context and a formal report |
| 4. | design, modify and evaluate experiments carried out in a laboratory context |
| 5. | develop problem solving strategies appropriate to new and context-rich situations |
| 6. | apply methods of analysis of experimental data, including graphical and numerical approaches |
| 7. | maintain a faithful record of work carried out in the laboratory, lecture and tutorial settings |
| 8. | apply skills in accessing information from a variety of sources including the Internet and the library |
| 9. | demonstrate the capacity to work both autonomously and collaboratively within time constraints |
Course intended learning outcomes (CILOs)
This subject also contributes specifically to the development of following course intended learning outcomes:
- Demonstrate theoretical and technical knowledge of broad science concepts and explain specialised disciplinary knowledge. (1.1)
- Evaluate scientific evidence and apply effective experimental design and/or mathematical reasoning, analysis, and critical thinking to apply science and/or mathematic methodologies to real world problems. (2.1)
- Work autonomously or in teams to address workplace or community problems utilising best scientific practice, with consideration to safety requirements and ethical guidelines. (3.1)
- Present and communicate complex ideas and justifications using appropriate communication approaches from a variety of methods (oral, written, visual) to communicate with discipline experts, scientists, industry, and the general public. (5.1)
Contribution to the development of graduate attributes
1.0 Disciplinary knowledge
Development of an understanding of the nature, practice and applications of Physics through lectures, tuorials and labs.
2.0 Research, inquiry and Critical Thinking
Development of an understanding of scientific inquiry by designing practical solutions to problems and undertaking careful and methodical analyses of data. Much of this will occur in the laboratory, which is a natural home for inquiry in physics. The process of engaging in, and communicating, the findings of inquiry enhances students’ capabilities in the areas of critical thinking and problem solving.
3.0 Professional, Ethical and Social Responsibility
Development of time management skills in order to work to schedules and meet deadlines. Develop an ability to work autonomously through journal activities done independently and collaboratively to complete tasks in laboratories and tutorials. Develop laboratory skills and data acquisition and handling methods in order to carry out scientific investigations ethically and responsibly.
5.0 Communication
Develop your ability to communicate in formal and informal situations in laboratories and workshops.
Teaching and learning strategies
Lectures: 2 hours online per week. Lectures provide an outline of key content and include worked examples. They are a guide for your learning and should help you stay focussed on the material covered in the subject. Additional explanations are provided in online videos while textbooks provide the most in-depth coverage. Immediate feedback of comprehension will be provided via in-class activities to assess student understanding of content.
Practical classes: 2-hr class on campus per week. Working in the laboratory is about building skills in teamwork, experiment planning, real world data collection and analysis, reporting and presentation as well as developing key technical skills with basic equipment. Prework for each lab class will help you assess your preparedness for the subject and prepare you for the work in the practical class. Feedback will be provided from demonstrators both face to face in the laboratory and with more detailed assessment of your logbook four times in the semester. See program for weeks when practical classes are held.
Tutorials: 1.5-hr class on campus per week. The tutorials will help you develop your learning of material outlined in online lectures. They will include problem solving sessions, a short overview of mathematics needed and peer discussion of new theory. You will work in small groups to develop solutions to problems and build your understanding of the theory. Immediate feedback will be provided during tutorial discussions.
Weekly quizzes: these short quizzes will support your learning by familiarising you with key concepts to be covered and helping you to assess your level of understanding. Completing the quizzes is required to unlock the resources on Canvas.
Expected weekly time investment per week in addition to the above hours: approx. 2-4 hours
Assumed Knowledge: Physics 1 (68101). You are also assumed to have a knowledge of mathematics including calculus, algebra and trigonometry.
An aim of this subject is to help you develop academic and professional language and communication skills to succeed at university and in the workplace. During the course of this subject, you will complete a milestone assessment task that will, in addition to assessing your subject-specific learning objectives, assess your academic English language proficiency. You may be guided to further language support after the completion of this subject if your results in this milestone task indicate you need more help with your language skills.
