The Structure and Function of Cells - an independent learning project Introduction The cell is the basic unit of structure and function; virtually all organisms consist of cells and cell products. This generalisation is known as cell theory. Research and write a report entitled ‘The Structure and Function of Cells‘. This should be a minimum of 6,000 and a maximum of 8,000 words, depending upon whether you tackle any of the extension tasks. The deadline for submission is June 21st 2012. This challenge has been designed to enable you to develop a deeper understanding of a key biological principle. You will also have the opportunity to apply your knowledge and understanding through some optional extension tasks. By completing the activities successfully you will also develop and reflect on your abilities in a range of functional skills (communication and IT) and learning and thinking skills. Aims This extended project offers opportunities for learners to: • have a significant input into the design of and take responsibility for an individual, defined task • develop and improve your own learning and performance as critical, reflective and independent learners • extend your planning, research, critical thinking, analysis, synthesis, evaluation and presentation skills • develop, where appropriate, as e-confident learners and apply new technologies in your studies • develop and apply skills creatively, demonstrating initiative and enterprise • develop and apply decision making and, where appropriate, problem solving skills. What are the Learning Outcomes? The learner will: • identify, design, plan and complete an individual project applying organisational skills and strategies to meet stated objectives • obtain and select information from a range of sources, analyse data, apply relevantly and demonstrate understanding of any appropriate linkages, connections and complexities ofthe topic • select and use a range of skills, including new technologies where appropriate, to solve problems, to take decisions critically, creatively and flexibly, and to achieve planned outcomes • evaluate outcomes including own learning and performance and select and use a range of communication skills and media to convey and present evidenced outcomes and conclusions. Resources You will be given a number of useful resource sheets to help start you off. A range of textbooks are available on request. The internet has a wealth of material if you search selectively, e.g. http://www.youtube.com/user/bozemanbiology. Functional skills Learning and thinking skills You will be able to demonstrate the following: Communication – reading and writing. This challenging project will allow you to develop as an independent inquirer, a creative thinker, a reflective learner and a self-manager. In particular you need to: In particular, you should: • check that material is consistently relevant, well-structured and appropriately presented, • clearly communicate your findings and conclusions which should be based on sound evidence and judgement. • complete the work applying organisational skills and strategies to meet the stated objectives • provide evidence of detailed research involving the selection and evaluation of a wide range of relevant sources. • demonstrate critical analysis and application of the research, with clear links made to appropriate theories and concepts. • complete a detailed and careful evaluation of the strengths and weaknesses of the completed project in relation to the planning, implementation and outcomes, and your own learning during the project. IT – use IT systems, find and select information, develop, present and communicate information. In particular you should: • take appropriate decisions and check that appropriate data is collected and thoroughly analysed, • fully implementthe project plan so that the outcome is fully realised to a high standard and consistent with the plan in the table of success criteria, • communicate your findings fluently in an appropriate format, synthesising information from a variety of sources and present them within a logical and coherent structure which addresses closely the nature of the task. Plagiarism and referencing Plagiarism is defined as the "wrongful appropriation," "close imitation," or "purloining and publication" of another author’s "language, thoughts, ideas, or expressions," and the representation of them as one's own original work. Please reference your work by acknowledging any sources you use throughout your report. This can be done by writing the author’s name and the date of publication in the main text (e.g. Champion, 2012) and then adding that source of reference material to your bibliography. There is a guide as to how to compile a bibliography further on in this booklet. Success criteria The following table outlines in detail the steps to take for successful completion of this report. Please note that three sections are optional extension tasks. Whether you choose to do none, some or all depends upon your interest, organisation and timemanagement. Please ensure you follow this checklist for the final report carefully. It will help you manage your time, structure your report, use resources effectively and review your progress and achievement. The word counts are a guide and the images are the minimum required – more may be included but be judicious with their use (each image must serve a purpose). Tasks Details, learning outcomes, advice, etc. Title Author IT format Create an eye-catching title page. Include your full name. A4 portrait in Word and check spelling, punctuation and grammar is UK. Sub-headings should be Arial font, size 14 and Bold. Main text should be Arial font, size 12, Normal. Text should be line spaced at 1.5 and aligned to the left. All pages should be numbered using a footer, except the title page. All images, diagrams, tables, graphs, etc. should be numbered (e.g. Figure 1, Table 1, etc) and include a short text of explanation. All figures should be referred to in your main text. References are cited in the main text to acknowledge the source of a piece of information. List the sub-sections in your report and page number. Summary of the key findings in your report.
