Understanding Essential Mechanisms of the Human Biology Assessment

Assessment Description

CO3. Describe the structure and function of the muscular, skeletal, cardiovascular, digestive and nervous systems.

For this assessment, you are required to record an oral presentation explaining ONE of the following biological processes:

• Bone Modeling and Remodeling
• Sliding Filament Theory of Muscle Contraction
• Blood oxygenation (from superior and inferior vena cava to aorta)

Your task is to clearly answer the following three questions for the ONE biological process you selected. You should use lay terminology and graphic aids, as you might to a patient or in an education session.

1. What are the key components involved in this biological process?
2. How does this process occur or work, step by step?
3. Why is this process important for overall body function or homeostasis?

You will create a presentation with four slides, one slide per question and a reference slide. The presentation should be between 3-5 minutes long. Unlike your ePoster, there should be minimal words (e.g. labelled diagrams are suitable) and instead, you must use images or graphics to support your explanation. You will also need to consult academic sources to plan your discussion surrounding the process (e.g. textbooks) and provide referencing for any graphics utilised (from other sources) within your slides.

Assessment Summary

Assessment Type: Oral Presentation
Learning Outcome (CO3): Describe the structure and function of the muscular, skeletal, cardiovascular, digestive, and nervous systems.

Task:
Students are required to select one biological process from the following:

• Bone Modeling and Remodeling
• Sliding Filament Theory of Muscle Contraction
• Blood Oxygenation (from superior and inferior vena cava to aorta)

The presentation must clearly address three key questions:

1. Key Components: What anatomical or cellular elements are involved in this process?
2. Process Explanation: How does this process occur step by step?
3. Importance: Why is this process critical for overall body function or homeostasis?

Presentation Requirements:

• 3-5 minutes in length
• 4 slides: one per question plus a references slide
• Minimal text; use labelled diagrams, images, or graphics
• Consult academic sources for content and graphics
• Proper referencing of all materials

Mentor-Guided Approach

The Academic mentor guided the student through the assessment in a step-by-step manner, ensuring clarity, accuracy, and adherence to academic standards:

Step 1: Topic Selection and Scope Definition

• Mentor helped the student choose Bone Modeling and Remodeling as the focus.
• Discussed the importance of selecting a process that could be effectively explained within 3-5 minutes.
• Emphasized understanding both structure (osteoblasts, osteoclasts, bone matrix) and function (growth, repair, homeostasis).

Step 2: Research and Content Planning

• Student was guided to consult textbooks, journal articles, and reliable online sources.
• Key components were listed, and stepwise processes were mapped out using flowcharts and diagrams.
• Mentor ensured the content was accurate, concise, and suitable for a lay audience, avoiding excessive technical jargon.

Step 3: Visual Design of Slides

• Mentor advised minimal text per slide, using labelled diagrams and arrows to illustrate processes.
• Each slide corresponded to one question:
  1. Key Components (cell types, bone matrix)
  2. Stepwise Bone Remodeling Process (resorption, formation)
  3. Importance to Homeostasis (strength, repair, calcium regulation)
  4. References (citing textbooks and academic sources for both text and graphics)

Step 4: Oral Presentation Practice

• Student rehearsed the 3-5 minute delivery with mentor feedback.
• Focused on clear, confident explanation, linking diagrams to spoken content.
• Mentor corrected terminology usage and suggested ways to engage an audience with minimal text.

Step 5: Review and Finalization

• Mentor reviewed slides for accuracy, clarity, and visual appeal.
• Ensured proper academic referencing and compliance with assignment guidelines.
• Student finalized the oral script and presentation visuals.

Outcome Achieved

• Student delivered a clear, concise, and visually engaging presentation on Bone Modeling and Remodeling.
• Successfully demonstrated knowledge of the skeletal system and related cellular mechanisms.
• Effectively explained the process in lay terms suitable for an educational audience.
• Met all assessment criteria, including content accuracy, time limits, minimal text use, and proper referencing.

Learning Objectives Covered

• Understanding of muscular, skeletal, cardiovascular, digestive, and nervous system functions (CO3)
• Ability to identify key components of a biological process
• Stepwise explanation of a physiological process using visuals
• Communication skills in translating complex biological processes into patient-friendly explanations
• Application of academic research and referencing in visual presentations
