Learning Approaches

This unit consists of weekly online theory material, a weekly tutorial session and a number of practical sessions.

The weekly online content includes online course material or narrated PowerPoints, and formative revision quizzes that cover the concepts and topics outlined in the learning content.

The weekly tutorials will revise the theory content and will reinforce your learning through revision exercises and activities conducted in class. Tutorials can be attended face-to-face or online and are recorded for future revision. Tutorials are essential to support your learning of the theory and are designed to prepare you for the practical classes, and theory exam. Moreover, these sessions are a weekly opportunity to ask questions to your unit coordinator and get feedback on your learning.

The practical classes are designed to develop and reinforce your professional practice, laboratory skills and upskill you in biochemical calculations, data collection and analysis, and results interpretation and critical thinking. Practicals will gradually increase in complexity as semester progresses by focusing on foundational skills at the beginning of the semester (i.e. biochemical calculations, use of spectrophotometer, use of calibration curves) and then exploring more advanced applications later in semester to solve biochemical problems related to health and disease (e.g. separation of proteins, comparison of metabolic enzymes in different tissues, and enzyme kinetics). The practical classes are supported by a teaching team who will actively guide you through the experimental work and research tasks and will provide you with feedback on your learning.

The unit coordinator is available during the practical and tutorial sessions for further assistance and feedback. The teaching program is supported by self-directed formative learning exercises and quizzes and other resources for learning on Canvas. Professional development and opportunities will be briefly discussed and explored in more detail in subsequent units.

Feedback on Learning and Assessment

You will receive progressive feedback on every component of your assessment. Specifically, you will receive feedback during practical classes on each research task conducted in the practical portfolio. You will also receive feedback in one of the scheduled tutorial sessions, and in postings on Canvas. The unit coordinator is also available for individual feedback on any summative assessment during or after scheduled classes.

You will receive formative feedback during the weekly tutorials and on the unit's Canvas site through the weekly tutorial revision and online quizzes, which include biochemical calculations, multiple choice questions and/or short answer questions. These will assist your learning in both laboratory practice and biochemical knowledge.

 

Assessment

Overview

This unit has two summative assessment items: 

Assessment 1: Laboratory/Practical demonstration (50%), consisting of research tasks to demonstrate technical and professional skills, completed during practical classes (e.g in weeks 3, 5, 7,11; the exact weeks may vary depending on calendar and public holidays);
Assessment 2: Final theory exam (50%), on campus during exam period.

In addition to summative assessment you will have continuous formative assessment in the tutorial sessions, on canvas site and during your practical sessions.

Assessment Tasks

Assessment: Laboratory/Practical

Practical Assessment Overview

As a biochemist working in a biomedical or research laboratory environment, you will engage in real-world research scenarios throughout the semester to demonstrate your technical and professional skills.

The practical assessment includes four research scenarios (each worth 12.5%, total 50%) completed during class and assessed with research tasks in weeks 3, 5, 7, and 11 (exact week may vary based on the calendar and public holidays). 

Research Scenarios

  1. Quantification of biomolecules using a spectrophotometer (assesses quantitative and lab skills to prepare samples, the use of a spectrophotometer and application the Beer-Lambert Law to quantify biomolecules);
  2. Protein quantification in plasma samples (evaluates preparation of standard curves, use of various protein quantification methods, and critical comparison of their accuracy);
  3. Separation and identification of isoenzymes in tissue samples for disease diagnosis (involves applying concepts such as protein charge and isoelectric point in separation techniques, the use of electrophoresis to separate and identify proteins, and the use of spectrophotometer to monitor enzyme kinetics)
  4. Determination of enzyme kinetic parameters (involves understanding the Michaelis-Menten model, using the Lineaweaver-Burk plot to calculate kinetic parameters, and identification of reducing sugars in biochemical assays)

Each research scenario builds on the previous one and gradually increases in complexity. You will develop foundational skills early in the semester (i.e., biochemical calculations, use of spectrophotometer, data plotting and determination of concentration using calibration curves) and apply them to more advanced analyses (e.g. protein separation, comparison of metabolic enzymes in different tissues, enzyme kinetics).

The practical class in the week prior to the summative tasks is dedicated to learn, consolidate and practice the skills. These sessions also include formative quizzes, and feedback from demonstrators to support your progress. Weekly tutorials and online content are aligned with the practicals to reinforce conceptual understanding.

This scaffolded approach supports the development of technical competencies and key learning outcomes, including professional behaviour, teamwork, and laboratory proficiency, preparing you for advanced studies.

Assessment and Participation

Research tasks reflect core responsibilities of a biochemist, such as sample calculations, experimental procedures, graph plotting, data analysis and interpretation of data sets related to the lab activities. Although you are assessed individually, lab work is conducted in pairs, with peer collaboration and teaching team support. You receive ongoing formative feedback from demonstrators during class, promoting reflection and continuous improvement.

Missed Practicals

If you are unable to attend a practical session with research scenario due to medical or other special circumstances, submit supporting documentation via HiQ within three days of the missed practical class. Acceptable supporting evidence of bona fide absenteeism can be approved for an alternative assessment during the next practical class. Please discuss with the Unit Coordinator directly on how this will be conducted. Unapproved absences will result in no marks for the associated assessment.
