Contribution to the development of graduate attributes This subject contributes to the development of the following: Graduate Attribute 1 - Disciplinary Knowledge Graduate Attribute 2 - Research, inquiry and critical thinking Graduate Attribute 3 - Professional, ethical, and social responsibility Graduate Attribute 4 - Reflection, Innovation, Creativity Graduate Attribute 5 - Communication

Teaching and learning strategies Lectures: 2 hours per week for the whole session Practicals: 2.5 hours per week Workshops: 2 hours per fortnight on average Online assignments Other student support resources are available, including UTSOnline Discussion Board and U:PASS. Students will adopt collaborative learning strategies in the inquiry-oriented laboratory sessions. Learning will be facilitated through active participation in a variety of hands-on and inquiry-based activities. Lectures and workshops are seamlessly incorporated into this subject. Online resources such as Youtube and simulations will be used to supplement pre-prepared materials which students will read before attending a lecture, workshop or laboratory session. All assessment items within the lab and workshop programs (for example, report, poster, and workshop exercises) are supported by feedback to students. This feedback is given continuously throughout the session. Mastering Physics is used for online assignments and this gives students immediate feedback on each attempted question.

Assessment Assessment task 1: Laboratory Work Intent:

This assessment task contributes to the development of the following graduate attributes: 1. Disciplinary knowledge 2. Research, inquiry and critical thinking 3. Professional, ethical and social responsibility 5. Communication

Objective(s): This assessment task addresses subject learning objective(s): 1, 2, 3 and 4 This assessment task contributes to the development of course intended learning outcome(s): 1.1, 1.2, 2.3, 3.1 and 5.1 Type:

Laboratory/practical

Groupwork: Group, individually assessed Weight:

30%

Task:

This assessment task has three components: Data Analysis Report - 10% that provides a means of determining whether students can perform the processes and skills required in laboratory work. The task requires the completion of practical exercises as well as answering questions related to experimental science (such as data analysis, graphing and calculation of uncertainties). Laboratory Report - 12% that requires students to integrate the scientific approach to experimentation in a formal manner by using a format consistent with discipline norms to describe experimental procedure, collation of results, analysis and conclusion. Poster and Presentation - 8% that requires students to reflect on their experiences and focus on the main themes. It is a good way

for groups to describe and explain their work. A verbal presentation accompanying the poster gives students practice in presenting and justifying ideas using appropriate general or technical language. Due:

Practicum period; see Further information

Criteria:

Assessment in the laboratory programme consists of the following elements: 1. Data analysis report, requiring students to complete some practical exercises, as well as answer questions related to the laboratory work (such as graphing and error calculations). 2. Laboratory report, based on the Solar Cell experiment. This is an authentic assessment task mirroring the practice of science and scientists. Students will likely work in groups, though each student must submit their own report (i.e. not a group report). 3. Poster and presentation, based on the Ultrasound experiment. Students are required to reflect on their experiences and focus on the main themes of the experiment. A verbal presentation accompanying the poster gives students practice in presenting and justifying ideas using appropriate general or technical language. Guidelines and rubrics for laboratory reports, posters and other aspects of laboratory assessment are provided in the laboratory manual and the Resource book.

Further Data Analysis Report: due 11.59 pm, 28 August 2020 information: Laboratory Report: due 11.59 pm, 21 September 2020 Poster Presentation: in your practical class during the week beginning 5 October or 12 October 2020

Examination

Groupwork: Individual Weight:

40%

Task:

Formal exam of duration 2 hours and 10 minutes reading time. The exam will assess student capabilities in critical disciplinary knowledge. It will be conducted under formal exam conditions. Questions will be of similar format to those in the assignments, workshops and Resource book. The exam paper will consist of two parts. Part A will contain multiple choice questions, which are drawn from all the topics covered in PAN including Experimental Methods. All questions in part A are compulsory. Part B will consist of three long questions, you only have to answer two of these questions (of your choosing). Equation and data sheets will be provided in the exam paper for your reference. This is a restricted open book exam. Students will be allowed to bring in one A4 sheet of notes (writing on both sides of A4 allowed). Revision material on this sheet can be written, printed or photocopied. The sheet must have your Name and Student Number in the top right hand corner of both sides. You may not remove your revision sheet from the examination.

Due:

Formal examination period (See Centrally-conducted UTS Exams Timetable for details)

Criteria:

Marks will be awarded based on students ability to: - answer short questions about physical concepts and principles - apply appropriate problem solving strategies and mathematical techniques to find numerical answers to problems

Minimum requirements Practical classes in subjects offered by the School of Mathematical and Physical Sciences are an essential and integral part of each subject in which they run. In addition to assisting students' understanding of concepts, practical classes develop important laboratory skills and experience that are desired by employers. Thus students are expected to attend all scheduled practical classes. Students need to...
