Assessment Assessment item 1: Laboratory Program Intent:
Assessment in the laboratory programme consists of the following elements: 1. Skills test, a practical examination conducted during a practical class. It requires the completion of some practical exercises, as well as answering questions related to the laboratory work (such as graphing and error calculations). Access to the log book during the test is permitted (but not the laboratory manual). 2. Laboratory report, based on the 2-week solar cell experiment. Each student is required to submit an individual report (i.e. not a group report). 3. Poster and presentation, based on the Ultrasound 2 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. 4. Prelab and logbook, requiring students to complete designated prelab exercises and keep an accurate record of activities in each practical session.
Objective(s): The laboratory program is designed to provide insights into the basic structure of physics and its relevance to other disciplines and the world around us. With this in mind, we have sought to expose students to assessment tasks they can expect to encounter in the future, both at university and in the work force. When designing the assessment program, consideration was given to the following broad issues that are consistently mentioned in the literature on assessment: reflects all the aims and objectives of the program reflects the learning and teaching styles being promoted in the program has a formative role, providing a means to enable students to consolidate their learning and monitor their progress has a summative role, providing a means of grading and classifying students tasks and their content are used by students to establish priorities in learning The program contains a variety of tasks that reflect the above criteria, provide a comprehensive profile of student abilities and reducing the likelihood of inadvertent cultural or gender bias.

Practicum period; see Further information
Task:
Skills Test - 10% that provides a means of determining whether students can perform the processes and skills required in experimental science. Lab Report - 10% that requires students to integrate the scientific approach to experimentation in a formal manner by using a predetermined format to describe experimental procedure, collation of results, analysis and conclusion. Poster and Presentation - 5% that requires students to reflect on their experiences and focus on the main themes. It is a good way for individual students or groups to display their work. A verbal presentation accompanying the poster gives students practice in presenting and justifying ideas using appropriate general or

Formal mid-semester examination period (See Centrally-conducted UTS Exams Timetable for details)
Task:
Formal exam of duration 2 hours and 10 minutes reading time
Criteria:
Questions will be marked against a detailed marking scheme developed by the subject lecturers
Assessment item 3: Online tutorial problems Intent:
This task requires the completion of six online assisgnments over the semester, each consisting of 4-5 problems and collectively spanning the broad topic areas covered in lectures.
Objective(s): To provide students with: problem-solving practice feedback on how well various lecture topics have been mastered. Weight:
15%
Due:
Not applicable; see Further information

Minimum requirements Practical classes in subjects offered by the School of Physics and Advanced Materials 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 a minimum overall score of 50% to pass this subject.
Recommended texts College Physics, 9th Edition by Serway and Vuille (available from Coop bookshop on Broadway). The lectures are closely integrated to this textbook, as are the online assignment problems.
Statement on copyright Australian copyright law allows you as a student or researcher to copy and use limited amounts of other people's material in your study or research without their permission and free of charge.
