Appendix A Appendix A: Guide to Formal Report Writing A formal report is an account of an experiment or project. It should be a well structured account, along the lines of an internal report within an organisation or a research paper in a journal. Just as the parts of a book (the contents, chapters and bibliography) organise the material in such a way that the reader finds it easy to determine quickly what the book is about, so the formal structure of the report enables the material to be accessible in an effective, efficient way. Generally your target reader is a fellow student who is at a similar stage on the course rather than an academic or postgraduate student. The report should be neatly prepared, preferably using a word processor, although clearly legible handwriting and carefully drawn diagrams are perfectly acceptable. However, if work does not meet a minimum standard of preparation then you may be asked to re-submit the report before marking by the assessor. Formal reports are an intrinsic and important aspect of your professional training and the Department puts considerable emphasis on encouraging you to develop proper reporting skills. During the academic year you will be required to prepare a number of formal reports for both hardware and project laboratories. In particular, please note the experiments that you are required to write up and the submission times, remembering that there is a 100% penalty for late submission. Poor attendance and inadequate log books are also penalised. In order for you to judge the quality of your work, marking is performed on a degree grade scale. The grading will be returned to you together with comments from the laboratory staff. Reports are graded on both their technical merit and their quality of presentation, therefore it is expected that the report will require a significant time and study resource during its execution. Reports must be well structured and written in good English. It is normal engineering practice to write in the third person passive (e.g. The circuit was constructed; the results are summarised in Table 3.) and to avoid the use of "I" and "we". The use of colloquial English and "chatty" phraseology should always be avoided. Also, try to avoid using superlatives such as "excellent", "very", "so accurate the results were beyond belief" etc. Try to vary sentence construction so that the material is not boring to read. Always aim for correct grammar; not to do so leads to misunderstandings, and increases the reader's efforts to make sense of what you have written. It is important to find a balance between writing short sentences, which get ideas over effectively and a sequence of single clause sentences which create a very broken rhythm. Vary it so that a good flow results. Structure and Content The most important part, the technical content, will come over when the structure and style have been sorted out. The process you carry out is one of interpretation. Ideally, the experiment which was performed was set out in a script structured in a progressive and efficient way to allow you to carry out the experiments and to develop the ideas which it was designed to illustrate. Remember that the structure of the experiment is Appendix A not necessarily the best for a report. Some modification will probably be necessary. With the benefit of having gone through the whole experiment, for instance, it may occur to you that certain parts can be grouped together to achieve a more concise explanation and so help you to develop your arguments. The technical content should include accurate (and complete enough for a critical examination of your analysis) information about the experiments which were set up and results in tabular or graphical form which can be used as a basis for comparison with theoretical expectations. Long derivations should not appear in text because they disrupt the flow of information. Often, derivations can be referenced if they have been done before; otherwise, if it is necessary to include some substantial analysis of your own, this is better in an appendix to the main work. It is not necessary to show intermediate steps in an elementary calculation: it is assumed you have the ability to do this correctly - but be sure that trust is well placed. If mistakes are apparent in a report, then the trustworthiness of other information starts rapidly to come under suspicion! In practice try to quantify your observations and where appropriate give an estimate of error and the expected value according to theory; this way your observations become meaningful. Normally a report will consist of some or all of the following sections: Title page: Title / student name / date / experiment number / laboratory session Abstract See below for example Contents list with page numbers of the sections of the Equipment list List equipment and codes for future reference report List of symbols and abbreviations 1 purpose Introduction 2 Theoretical section(s) 3 Procedural section(s) 4 Results section(s) 5 Conclusions Acknowledgements References Appendices setting out the background to the subject and the of the work Appendix A The headings "Theoretical sections / procedural sections / results sections" are not the headings you will use in practice. In your reports you should choose formal but descriptive section headings that convey the content of the particular section. All sections should be numbered using sub-headings as appropriate. For example, 2 The 'current-dumping' amplifier 2.1 Output-stage design 2.2 Derivation of balance condition The object of a report is to convey information to the reader in a direct and efficient way. Therefore, structure and careful organisation of ideas is important. The "Introduction" and "Conclusions" should give a high-level overview to the work, setting out what is to be done and then commenting on the results of the investigation and indicating what has been discovered. The Conclusion should therefore link with the Introduction and be critical of the findings. These two sections should "stand alone", conveying the important aspects of the report without the necessity to read all the fine detail (this would be of particular use to a manager who needs to know what you set out to do and what was concluded but may not have the time to digest the finer detail of the report as a whole). Also, when further investigations may be appropriate, these can be detailed in the Conclusions or a separate section discussing recommendations for further work. Abstract At the commencement of your report there should be an Abstract. This is a 50 to 100 word, succinct précis of the report emphasising the key features. The Abstract needs to be "tightly" written, with no wasted words or phrases. In practice, an Abstract may be documented in isolation to the report and is available to give concise background to a work so as to inform the reader as to its basic contents. You are recommended to examine a range of technical papers to see how Abstracts are written in practice. However, an example is as follows: A family of asymmetric crossover filters is investigated that expands the established all-pass set. A general method of determining complementary crossover filters with an all-pass composite response is presented together with a method of reflecting the crossover asymmetry about the crossover region; a number of example filters are included. CAD techniques are used to verify the basic approach and a simple application to a satellite/sub-woofer loudspeaker is described where asymmetry in the crossover frequency response and the resulting overlapping of the high-pass and lowpass responses is shown to improve the effectiveness of filter attenuation. However, because of asymmetry in the high-pass and low-pass phase responses and the resulting polar response irregularity in association with non-coincident drive units, the application regime for these alignments is restricted to low frequency. References Appendix A It is expected that in preparing your report you will use reference material (your allocated marks will reflect this). This must be properly presented with references listed near the end of the report and referenced appropriately in the body of the text. Developing the proper use of reference material cannot be emphasised enough and you are encouraged to follow good referencing practice for all your technical work, not just formal reports. Your attention is also drawn to pages 18-21 that include information relating to cheating. An example format for a reference appearing in the list of references is as follows: [Bor93] Borish J and Angell J B, "An Efficient Algorithm for Measuring the Impulse Response Using Pseudo-random Sequences", J. Audio Eng. Soc., Vol.31, No.7, 1993. or [1] Borish J and Angell J B, "An Efficient Algorithm for Measuring the Impulse Response Using Pseudo-random Sequences", J. Audio Eng. Soc., Vol.31, No.7, 1993. In the text of the report, when you wish to indicate that information has been derived from this particular reference or you wish to indicate to the reader that this article provides additional information, you should include [Bor93] or [1] at the appropriate place. Appendix A Notation It is expected that you will use correct SI unit notation for all technical documents. There are correct procedures to be followed and a professional engineer will use these conventions. To help encourage you in this endeavour, you will be penalised for incorrect use of notation, so please read Appendix B and observe the conventions. The report should contain adequate theoretical background. However, where relevant theory exists in a book or paper then the result(s) can be stated and appropriately referenced. Alternatively, if you wish to develop and include a particular analysis it may impede the reading of the report. In this case the additional material should be presented in an appendix. This way the report remains complete but the reader is not distracted from the flow of information and ideas; this is particularly relevant if an analysis is not essential to a proper understanding. Results The report should be critical of sources of error, as all physical measurement systems are subject to error, thus you should make estimates of the likely accuracy of results. It is recommended that a study of combining multiple errors in numerical evaluations should be made. Report length The report should be a comprehensive account of the topic but not over long. We ask you to limit formal reports around 3000 to 5000 words (maximum) or 14 pages of text (appendices can extend this length). To give an adequate account of the work which occupied many hours in the laboratory is not a trivial task and while it may be more laborious to write a longer report, excess length is often the result of laziness at the planning stage. The laboratory assessors are rarely impressed by length; quality is what counts. Of course, a long report may be excellent throughout but note in the first place that if the material and organisation of a well proportioned report is of high quality, it will earn good marks anyway. Remember that success in communication results from retaining the interest of the reader - who may not have the time to digest more than a certain volume of material. In summary, the IET brief on report writing summarises good practice in the form of ten 'laws' listed below. 1 The reader is the most important person. 2 Keep the report as short as possible. 3 Organise for the convenience of the report user. 4 All references should be correct in all details. 5 The writing should be accurate, concise and unobtrusive. 6 The right diagram with the right labels should be in the right place for the reader. 7 Summaries give the whole picture, in miniature. 8 Reports should be checked for technical errors, typing errors and inconsistency. 9 The report should look as good as it is. 10 The reader is the most important person. If you try to obey them when you write your reports your work will be well-received.
