    How you’ll learn

    There are a variety of ways you can learn and interact with the materials in this course.

    Self-paced learning – This online course is set up so you can learn at your own pace. Although there are ‘suggested’ times for each page, they’re just a guideline - plan your learning to suit you.

    Diagrams, videos and interactions – Some people prefer to learn by reading, some by watching and listening, and some by doing. We’ve used diagrams, videos and interactions alongside the text, so that there’s something for everyone!

    Practice activities – Throughout this course there are short activities. These activities are for you to check your own understanding, not for someone to mark them. These activities give you a great chance to practise what you’ve learned and compare your answer with the model feedback without having to be assessed. That said, they’re also an excellent way to prepare for your final assessment for this achievement standard!

    Glossary – We’ll be using some technical words and phrases in this course to do with micro-organisms. It’s important that while you’re learning about the different concepts, you’re also growing your own vocabulary around the topic – you’re expected to know certain terms when it comes to your assessments. To help you with this, the course includes an online glossary. When you see a word or phrase underlined in the text you’re not sure about, move your mouse over it and a definition will pop up – easy!

    So, let’s get started!
