Writing technically Skills Writing Technically – Writing the Report Description of this Guide This guide comprises two parts: Part A – Writing the Report contains information and activities on collecting data from your log book, on how to get going and finally produce a report with the correct sections and understand what you need to do in each of the sections. Part B - An Interactive Grammar Guide focusing on writing objectively (using the passive), writing clearly (understanding the clause), being precise and accurate, linking ideas and correcting four of the main grammatical sins in writing. If you have a writing assignment coming up soon, it would be good to read and work through the activities in Part A. If you just want to work on your grammar go straight to the Interactive Grammar Guide. It has many links to online sources where you can further test yourself. Learning Outcomes 1. Understand the function of log/lab books and what they include. 2. Manage the writing process (think, plan, write, revise, and edit). 3. Understand the structure of paragraphs and the role of topic sentences and thesis statements. 4. Understand the sections of scientific/technical report. 1 Contents PART A Writing the Report 1.0 Introduction 2.0 The Process of Technical Writing 2.1 The Lab Log (Notebook): documenting your research 2.1 Checklist for Lab Notebooks 2.2 The Process of Writing your Report 2.2.1 Planning and Writing your report A Think: what does your reader want to know and what do you want to say?

These can be for example research papers, technical reports and newspaper articles. Being able to write effectively therefore is essential for the scientist or the engineer. Experimental and project work at University is an excellent opportunity to produce simple, clear and readable reports for a specific audience. It is important to be aware that you need to learn this skill, and the more you practise the better you will become. The hallmark of good technical writing is clarity. If you are able to present your ideas clearly you are also training yourself to think clearly. This guide will help you to master the process of writing, which can be difficult for most of us and identify the contents of each section of a report. Writing the Report is Part A of the Writing Technically guide and should be used in conjunction with Part B - An Interactive Grammar Guide as well as the other guides on the Academic Skills website at http://www.academic-skills.soton.ac.uk/develop.htm 2.0 The Process of Technical Writing The process of writing is the difficult part. It is not only your ability to string a sentence together, but also how you manage the process. Get the process right, and you will feel a lot more confident. 2.1 The Lab Log (Notebook): documenting your research As an Engineering or Science student you will be carrying out work in the laboratory, and as any good professional scientist or engineer, you will be expected to keep the lab log or lab notebook. In this log you will record, in note form, details of each lab session. You should complete your lab log during your lab session so you can record observations and any key data as it occurs. Make sure you come to a conclusion at the end of every experiment. Your lab log should be a hard-backed book that will serve as a diary for all your lab sessions. The lab log may be all that you have to write, but if you have to write a lab report, then you will need the information in your lab log to work from. Remember, to record all your observations accurately. Writing technically Skills Activity 1 : Headings for your Lab Notebook Match the number with the letter…. 1. Table of contents 2. Description of your work 3. Experiment 4. Materials and equipment 5. Methodology 6. Data 7. Results 8. Brief discussion A. Give it a title, write down: the question you are trying to answer and your hypothesis. B. Use graph paper software packages to display your findings, ensure everything is labelled correctly. Make sure this relates to your hypothesis. C. Lists experiments and investigations and the page number D. A list of everything you need to carry out this experiment E. Briefly state what you did in a few sentences F. Did you have appropriate evidence for your hypothesis, state what you’ve learnt, how you would improve your experiment. G. Say how you carried out experiment, add diagrams H. Prepare data tables beforehand and explain what should data represents See Key to Activities 2.1.1 CHECKLIST FOR LAB NOTEBOOKS 2.2 Write with a PEN not a pencil. Date and title your lab session. Write simply and clearly so that someone else could repeat your experiment from your notes. Prepare data table beforehand and complete during the experiment. Put a line through mistakes and make clear corrections, explain what changed and why. Make drawings where necessary. Record your results carefully, make conclusions, offer suggestions and evaluate any errors. The Process of Writing your Report Before writing your lab report check: Who this report is for (the reader). How you are going to structure it (your tutor may have the template for you to use). 5 That you have all the information you need from your experiment (see your lab notebook). Relevant references for your literature review in order to place your work within a body of scientific knowledge. (Check with your tutor if this is necessary for your report). You will probably assume that your reader will be a tutor. However, since your tutor knows this topic, you may feel you do not have to ‘spell everything out’. So, it may be better to write for a friend who is interested in this topic, but does not know too much about it. This way, you need to make everything clear. Having a reader in mind is very important. This determines how you write. 2.2.1 PLANNING AND WRITING YOUR REPORT Assume you have carried out your investigations and you have a reader in mind. It is now important to: think, plan, write, revise and edit. This applies to any piece of work you are writing. A THINK PLAN WRITE REVISE EDIT What does your reader want to know and what do you want to say? Take a report you will be working on and complete the table below (or use a mind map). Question Why this investigation? Purpose, objective(s) and scope of your report Who else has done work in this area? some key references How did I/we do it ? method and equipment used Where did I/we do it? Relevant if you did fieldwork What did I/we find out? Results and conclusions Working title Your notes Writing technically Skills These are all questions that the reader will want answered when reading your report. You may prefer to create a mindmap that at this stage. The University workstations have a mindmapping tool available (Inspiration). B THINK PLAN WRITE REVISE EDIT Plan your working with structure. You will need to know the structure of the report you are writing. Check with your tutor as he or she may have a particular structure for you to use. Also, if you are lucky enough to write a paper for a journal, you will need to check the structure, formatting and referencing style for each Journal. A typical structure for a report is: 1. Abstract 2. Title 3. Summary (abstract) 4. Keywords (optional) 5. Table of contents (advised) 6. Introduction 7. Literature review 8. Method (procedure, equipment) 9. Results & Analysis 10.Discussion 11.Conclusion and Recommendations 12.References - see Referencing your Work guide at http://www.academic- skills.soton.ac.uk/develop.htm 13. Appendices (large tables of data, illustrations etc.) The structure of your report may be a lot simpler, but those sections in bold will almost certainly be included. More details of the structure are provided in section 3. 7 PLANNING TIPS: Look at your notes from the think section above. Start to outline a few sentences for each section in your report. You don't have to do this in order, but do group sentences in the right section and try and place them in some kind of order, even though it may be rough at this stage. If you are a visual learner, you may prefer to do this as a mind map, but do try to constructs sentences. As mentioned earlier, the University workstations have a piece of software called Inspiration that can help you do this. Look back at your notes, your lab notebook and your results to help you do this. Sentence outlines help you get started and before you know where you are, your report is underway. Take a piece of scientific/technical text – a section of a chapter or a scientific paper would be ideal. Take the first sentence of each paragraph and write it down so you have a list of sentences. From each sentence identify what the paragraph will be about Go back to the text and see how accurate you were. Now do this with some piece of text you have written. A good writer will use the first (or first two) sentences of a paragraph as a pointer to what is in that paragraph. You intuitively know this as a reader as the text will be coherent. If you write a sentence for each idea you have, this will be the outline of your work. Check out section 2.3 for more information on this. C THINK PLAN WRITE REVISE EDIT Just start somewhere……….. It was suggested above, that when you Plan you can use sentence outlining as a way of identifying what you want to say. It also means that you have started to write and bypassed the blank white page syndrome that many writers face. Now you have some skeleton sentences in each or most of your sections, try developing some sentences in a section you feel most comfortable with. Very often writers feel that the Methods section is the easiest place to start as it is the most concrete. Your sentences should be simple and clear. Your ideas are developed through your sentences, so make sure they are put together logically. Each paragraph then develops an idea or concept. Writing technically Skills NOTE: When you are writing sentence outlines in the planning phase, the sentences will probably express an idea for a paragraph. If you have several sentence outlines for a section this will probably correspond with different paragraphs within a section. In the writing phase, you need to develop these ideas through supporting sentences. Check the activities in Part B, section 4.1 ‘sentence fragments’. The activities in the section are important when you come to revise your work. D. THINK PLAN WRITE REVISE EDIT Check you’re making sense! You revise your work to check it is making sense, possibly adding or deleting things, and refine the way you have expressed yourself. You should revise your work after each section, and then finally look at all the sections when reviewing the whole work. You must revise your work. If you leave your write up to the last minute, then you may find you have no time to do this. Make sure your time management includes revision. Most experienced writers have several revisions whereas poorer writers tend to just produce one draft. Be prepared therefore, for several revisions. See guide Being an Independent Learner section 2.0 on time management on the Academic Skills website: http://www.academic-skills.soton.ac.uk/develop.htm. What you must do…. Check your work covers what you have to do for your assignment. Read your work critically -check you have a strong message that is clearly argued and logically presented. Is your message coherent and logical within paragraphs and between sections? Check for any repetitions or things you can delete. Check paragraphs are in the correct order- you can re- order them. Think of your reader – check you haven’t introduced an acronym without an explanation. Check that your results clearly presented and your figures support what you're saying. 9 REVISION TIPS Use a word processor so that you can move text around easily during this phase. Make sure you save each revision with a different name in case you want to go back to an earlier version. This is a very important house-keeping skill to develop. Check the activities in Part B, section 4.0 for exercises to avoid the main grammatical sins. E THINK PLAN WRITE REVISE EDIT Check for errors Sometimes the revision and editing activities get done together. This is not a good idea. During the revision you're looking at the content and how you have expressed it. During the editing phase you're looking to surface errors, e.g. typos, spelling mistakes, bad grammar, inaccurate labelling of figures and tables, and incorrect referencing. This is a much like proof reading. What you must do….. check your: Sentences are complete and make sense. Style of writing – check your use of the passive? Do a search for ‘I’ or ‘We’ and check if this needs to be converted from active to passive. Spelling is correct. Citations (names of authors you refer to in your text) - check they appear in your reference list. References are written in the correct way. You will probably need to write them using the Harvard system (see guide Referencing your Work: http://www.academic-skills.soton.ac.uk/develop.htm ), but first check with your tutor. Writing technically EDITING TIPS Skills Read your work aloud – or into a tape recorder. This prevents you from skimming over what you have written and missing things. If your tutor is happy with peer review (i.e. enlisting the services of a fellow student), this is an excellent way to check your work. Use the spellchecker and grammar checker in Word (with caution). Use of bibliographic software (Endnote or Reference Manager) that is available in all public workstations (a guide to using Endnote can be found at http://www.academic-skills.soton.ac.uk/develop.htm). If you have difficulty doing this phase of your work, it could be that you are dyslexic or have visual difficulties, then check out the technology available to help you in the Assistive Technology Service, located in the Hartley Library. Website: http://www.ats.soton.ac.uk/ . See activities in Part B, section 2.0 2.3 Developing your message through paragraphs You can develop your message by: 1. Thinking about the topics you want to include (outlining). 2. Writing a thesis statement (a sentence or two focusing on the intent and scope of your work). 3. Writing topic sentences (a key sentence in each paragraph that identifies the topic of the paragraph). OUTLINING : USING A THESIS STATEMENT AND A TOPIC SENTENCE Outlining links to your thinking and planning phase. You can outline: topics, section titles (if not using a predetermined template), topics within sections, your arguments, and your results etc. Outlining helps you develop a framework for a coherent report or essay. You can start to see the shape of your work, what you already know, and what you need to find out. Your outline can be in note form, or in complete outline sentences. The advantage of writing sentence outlines is that you have made a start and these sentences will probably refer to the topic of a paragraph. This is an excellent way to start writing and it will be easier in the long run. Sometimes your coursework will include this outlining phase and full sentence outlines will be expected. WRITING A THESIS STATEMENT A thesis statement is a statement that lets the reader know the purpose, scope and direction of your report. When you prepare your outline, you need to do this in a way that supports your thesis statement. At the beginning, you may just want to jot down some ideas for the statement rather than write a complete sentence. 11 Go back to the set of questions in section 2.2.1. If you answered the first question, Why this investigation? - then you should have the beginnings of a thesis statement. Your whole report will revolve around this and any hypothesis that you write for your experiment will relate to the thesis statement. A thesis statement is very specific and reflects the contents of your report. For technical writing, your thesis statement will comprise: Your topic of investigation. Elements considered in your investigation. The order you will be presenting the information. Generally, the thesis statement will come towards the end of the first paragraph in the introduction. You sentences before this will be setting the context. For more information see: Purdue Online Writing Laboratory http://owl.english.purdue.edu/handouts/general/gl_thesis.html University of Wisconsin-Madison http://www.wisc.edu/writing/Handbook/Thesis.html WRITING TOPIC SENTENCES: SENTENCE OUTLINES Outlines are usually constructed with topic sentences. A key sentence in a paragraph that identifies the topic of that paragraph. All paragraphs should have one. So, this sentence should be as specific as possible. You can always elaborate on this when you come to write the full paragraph. Remember, your topic sentences will be in support of your thesis statement. See also the Writing Effectively guide, section 3 for paragraph development.

Check: Format you may be expected to use. Font and point size are consistent (don’t develop fontitis). Margins are what they should be. Headings (choose a slightly different style across different levels of headings – but use them consistently). Citations and referencing formats that you have to use. The document should be easy to navigate and this helps with: Clearly laid out title and your name. Table of contents (if your document is short this may not be necessary). Numbered sections with titles. Clearly labelled tables and figures (select an appropriate font for these). Where necessary refer to them as figure xxx: title or table xxx: title. TIP If you are preparing a long document, or many similar documents select your style for all the headings and body of text and create a style sheet in Word. Elements of Technical Writing: Document Design from Free Education on the Internet http://www.io.com/~hcexres/tcm1603/acchtml/page_design.html 2.5 Other Reports Technical reports have many functions, for example: evaluation, recommendation, technical specification, guides or manuals. For more information on these different types of technical reports see this e- Book to technical writing at: http://www.io.com/~hcexres/tcm1603/acchtml/acctoc.html As a student you will be involved in group projects. This will often involve a group report. In preparing your group report check you have: Covered the criteria for the assignment. Understand how to work in groups (see Working in Groups guide http://www.academic-skills.soton.ac.uk/develop.htm). Know what your role is in the group. Devised a group approach to your report where you can all contribute to its writing. Linked its contents to an oral presentation where this is required. You will also be asked to write essays. A good site for checking out how to write a E.E.E. technical essay is from the University of Glasgow at: http://www.efl.arts.gla.ac.uk/eee6/ and comprises: analysing the title, gathering information, and organising information. See also the Writing Effectively guide. 13 3.0 Writing the Sections of your Report Scientific and technical reports have fairly standard sections. Some reports contain the full set of sections while others a subset. You will need to check with your tutor the sections he/she wants you to include in your reports. This guide gives you some idea of what needs to be included in a selection of the sections. 3.1 The Summary/Abstract Always write the abstract/summary last, even though it is placed at the beginning of your article or report. Summary This is a paragraph or two giving a clear statement of the purpose of your report/paper, your main findings and conclusions. Note the confidence you have in your findings and any reservations. Information should be in the same order as the report, but you should not make any cross reference to the body of the report. Remember you read the title and summary/abstract of a paper/report in order to see if it is of interest to you. You do not want to read the whole paper and then find out it was not relevant. Abstract An abstract is also the summary of an article in a published journal. The abstract will be published with and separate from the body of the article. So, it can be read without access to the article (e.g. on remote databases and abstract journals). Therefore, it must give you enough information to make a decision on whether you should read the whole article. An abstract is usually about 250 words. 3.1.2 Checklist for your Summary/Abstract Purpose of your report. Key findings. Main conclusions. Source: Engineering Communication Centre For an example of an abstract see the Engineering Communication Centre at http://www.ecf.utoronto.ca/~writing/handbook-lab.html 3.2 The Introduction This section sets the scene and contextualises your work by giving the necessary background. This is your shop window (along with the abstract if you write one) so it is important to write clearly and interestingly. This should explain why you are carrying out this investigation (see section 2.2.1 and the notes you took while you were thinking about your report) and who else has done similar work. The writing here should be engaging, simple, clear and relatively non-technical. Writing technically Skills 3.2.1 CHECKLIST FOR YOUR INTRODUCTION This is not a complete list - check with your tutor. A paragraph discussing the topic of your investigation, state any assumptions your work was built on. Some information on any previous work in the field relating to your topic o key findings from other researchers and/or o approaches to tackling this issue State your hypothesis, if you have carried out experiment or a clear statement of a problem you are trying to solve. Cite any references you use in your text and include in your reference list at the end of your report. (see Referencing your Work at: http://www.academicskills.soton.ac.uk/develop.htm ) NOTE: You may want to have a literature review section on its own. Ask your tutor what he or she wants. 3.3 The Methods Section This section should be written clearly enough so that the reader could repeat your experiment if he or she wanted to do so. This will also help the reader understand how your data was obtained. Your sentences should be simple and clear. You need to write in the past tense and use the passive. If you don't understand what the passive form is, then go to Part B, section 2.0. When you use the passive, you concentrate on what you DID and underplay WHO did it. This gives your report a sense of objectivity, which is essential in technical writing. NOTE: This section may be divided into: methods and materials (or equipment) and experimental procedure. Ask your tutor what he or she requires. Remember, you can save a lot of writing by including a well-labelled diagram. 3.3.1 CHECKLIST FOR THE METHODS SECTION List the equipment used (add diagram if important). State any conditions of your investigation. State the purity and structure of the materials used if important to your investigation. State exactly what you did. Describe the techniques used. Use standard abbreviations for names of things. 15 See exercises in Part B, section 2.0 on the passive. 3.4 The Results & Analysis Section Here you will present your main findings (adjusted and analysed) and identify important trends or information. This section will be full of tables and graphs that will depict all your significant results. You will need some text so that the reader can easily interpret your figures and identify your variables. However, your comments should be short, clear and precise. See below some language you could use - note the style of language. It should be clear and precise, drawing the reader's attention to your findings without you commenting on the results. It is clearly evident from …….. that ……. According to Figure 1, it is clear that ……… it is evident that……… As can be seen in Table 3, there was an 4.5% fall in …… there was a 4.5% increase in… As a result of ………… there was a 3.5% rise in…………….. Make sure your graphs and tables are well laid out and accurately labelled (informative title, labelled axes, legend - when appropriate, units used, numerical values along the x-axis). Always refer to numbers and quantitative measures if possible. Check out: X is quite a lot larger than Y | X is 6% larger than Y. Writing technically Skills 3.4.1 CHECKLIST FOR THE RESULTS SECTION 3.5 Identify key data that relates to your hypothesis. Analyse and summarise this data. Present your data in clear graphs or tables. Briefly comment on the results to help the reader understand your data. Add key calculations as appropriate. Raw data should be in an appendix - if required. The Discussion Before you start this section, get your story straight. What do you want to say about your findings? Here you need to link your results with your introduction to form a critical view of your work. It is important that your writing here is evaluative, this is the most important section. You need to convey to the reader what you results and findings mean. Below are some questions to start you thinking about this section discussion. Apply them to a past experiment or investigation - make notes below. 1. Re-state your purpose So, what were you trying to do? Use the past tense. test a hypothesis try to replicate someone else's study test a new technique/protocol evaluate the findings of others anything else? 2. Interpret your data Do your results support or reject your hypothesis? Remember your claims have to be supported by your data. NOTE: check with your tutor how much you need to do in this area for your assignment. 3. Briefly re-state your method in relation to your results Were there any limitations in your method that could have affected your results? This refers to experimental error and tolerances. Is this acceptable? Are your results still valid? Could this be improved? Look critically at your work. Use the past tense. 4. Set your work in relation to others How does your work relate to others who have undertaken similar investigations? Use the present tense. NOTE: you may not need to do this for your assignment, but check with your tutor. 17 5. Analyse the strengths and weaknesses of your experimental design How do you feel about your experimental design? What were the strengths and weaknesses? Did it effect the reliability of your results? If something didn’t work be honest and try to analyse why. 3.5.1 CHECKLIST FOR THE DISCUSSION 3.6 Re-state your purpose and hypothesis (if appropriate). Interpret your data and comment on your findings. Re-state key elements of your experimental design/method in relation to results (experimental error/tolerances). Comment on your confidence regarding the validity and reliability of your findings as a result of your design. Be quantitative whenever possible. Be objective and avoid vague general statements, such as, “ I felt it was quite successful” ! Comment on your results in relation to others – expected or unexpected. Cite others’ work as appropriate (see Referencing your Work guide http://www.academic-skills.soton.ac.uk/develop.htm) . Summarise and critically evaluate your research design and findings. The Conclusion You may include the conclusion in your discussion. Check with your tutor what is needed for your assignment. If you do include this section, you may want to move your critical comments about your research design into this section and then talk about how you could improve it in the future. What’s wrong with this and what do you need to do to make it acceptable as a scientific text? “I think this experiment was quite successful.” Writing technically Skills 3.6.1 CHECKLIST FOR THE CONCLUSION Briefly state what you found. Support this statement with key findings. Comment on how future research could develop this topic. 3.7 The Appendices Typically these include the following – put them in separately labelled appendices. Raw data (as necessary). Calculations. Pertinent detailed graphical information such as NMR, graphical output from tests etc. Any detailed information about the apparatus/equipment as is necessary. 4.0 Developing your style Writing, as any skill, improves with practice. The more you write, the more confident you will feel. You should however reflect on how your writing skills are developing and identify areas for improvement. Do you …. then look at …. … find you can't get going? Think, Plan, Write section 2.2.1 (A,B,C) … find you have lots of mistakes pointed out when your work is handed back ? Revise, Edit, Section 2.2.1 (D,E) … get confused about what you should write in each section? Section 3 ... find your tutor corrects your grammar quite a lot ? Part B Interactive Grammar guide … feel unsure about referencing? See Referencing your Work guide at http://www.academic-skills.soton.ac.uk/develop.htm … feel unsure about plagiarism?
