You should consult the undergraduate handbook/ School guidance booklets on writing assignments and project reports, if needed. It is helpful to write clear and well-structured assignments, where you present your argument lucidly and in an informed manner, with due reference to appropriate theoretical concepts and relevant real life examples. Read around the topic, assess the issues involved, summarise your main points, think of a suitable analytical framework and essay structure, then write your report. Or, to quote Lewis Carroll (Alice’s Adventures in Wonderland, Chapter
assessments, online textbook quiz, critical thinking page for understanding the skills they learned, chapter review with questions to answer, and standardized test practice. First there is a section that familiarizes the student with what they will learn in this unit. The next section shows the vocabulary context and
You will have to write a hypothesis, identify variables, discuss testing methods, and design your own experiment. (Please note that what I have written in the teacher version is an EXAMPLE. You may add to, delete, or edit the responses in any way. It is designed to help you understand the notes more completely and to become familiar with my website.) Please write your answers and then place these notes in the NOTES section of your binder.
