Report Writing in MS Word 2007


Introduction

Technical report writing is an important skill.  It's much more precise than many other forms of writing.  A project report is not quite the same as a technical report, however it should show the same level of care and attention to detail.
This document was written to provide a few pointers about what I look for in a project report, and some tips for writing these documents using Microsoft Word.  It is written in the form it recommends, and contains examples of both good and bad styles.  It is intended for undergraduate project students, and post-graduate students in their first year.  It assumes a reasonable familiarity with Microsoft Word (although not at the level of an expert user), and a reasonable grasp of English grammar.


1.1    Background to the Report

Please note that there is no accepted standard for project reports.  Different supervisors will have different opinions and preferences about style; in some cases this document merely describes my preferences and opinions.  Any student reading this document would be well advised to talk to his or her other supervisor as well, and attempt to write a document to satisfy us both.
Distributing this report written in Word has two additional benefits: it allows me to give examples of what I regard as good (and occasionally bad) styles, and it gives me the chance to distribute a sample style gallery that might be of some use.  (If you don't know what a style gallery is, look it up under Microsoft Word help.)

1.2    Writing Reports for Me

This is important, I want everyone to read this, so I’ll put it here.  Strictly speaking you could argue that this section should be placed in the body of the report since it is not an introduction to anything that is discussed in more detail later, but since it’s short I can get away with it.
I am happy to read draft copies of a report before submission.  However, I am not happy to read slightly different versions of the same chapter over and over again, and I won’t have time to read anything if I am presented with a large document only a few days before the deadline.
I have come up with a few rules for how this can best work for both of us:
  1. Run all chapters through a spelling and grammar checker before they get to me, and take note of the advice provided.  This is particularly important if English is not your first language.  If the grammar and spelling are so poor that I have difficulty in understanding what you are trying to say, then be prepared to have the document returned.  I’m afraid I don’t have the time, experience or qualifications to teach English as a foreign language. 
  2. Send me individual chapters one at a time, as soon as they are complete (or as soon as you want some comments on them).  This minimises the amount of reading I have to do at the end of the projects, and I hope will encourage you to write as you go along, always a good idea.
  3. If you are sending me a chapter for the second time, then please clearly mark where the changes have been made, so I don’t have to read through the whole thing again.
  4. If English is not your native language, it is almost certain that there will remain a lot of grammatical and usage points which the computer’s grammar checker will not pick up.  Experience has suggested that the best thing is to leave these until the end, and then for a native English speaker to go through the document once, to correct the grammar.  It is better if this person has not been involved with the project, so they don’t get too bored.

   The Basics of Project Report Writing

Some basic techniques and considerations about writing project reports: when to write; the structure of the project report; what sections should be included; what order they should be placed in; and what kind of information I am looking for when I read a project report.
There are a lot of good introductions to report writing out there already (see for example, the information at http://www.amp.york.ac.uk/internal/ugrad/gen/tskills/t_skills.htm), and I won't try and repeat all that information here.  I will assume the reader is familiar with this material already (if you're not, do look up and read these pages).  Instead, I will concentrate on the particular nature of the project report and highlight what I have found to be the most common problems.

Window Operating system (Unit III)

                            What is Windows?
An operating system and Graphical User Interface (GUI) created by Microsoft and found on most computer systems (but not all!).
• Allows for easy “point and click” operations between the user and the different files and programs with which they wish to work.
• While there are many different versions of Windows, the fundamentals are the same.

Menu bar:
• On many windows you will see a menu bar, which allows you to access features within that particular program.
• Office 2010 programs have a menu bar as well, but it’s configured differently and is called “the ribbon”
Scroll Bars.
• Scroll bars often appear at the bottom and even more often on the right hand side of a window, if there is a lot of content.
• Scroll bars are disabled when the content displayed is limited enough to fit within the dimensions of the window.


Cut/Copy/Paste
• Cut , copy, and paste commands can be used with to move text, graphics and other items from one
application to the next (Internet Explorer to Microsoft Word, for instance).
• Copied or cut items are placed in temporary storage (the Clipboard) and can be retrieved as
long as the computer is on or if the item hasn’t been replaced by another that you select.
• An item on the Clipboard can be pasted multiple times.
 

Cut/Copy/Paste
1. Select the item (text or graphic) to be copied by either highlighting the text or right clicking on the graphic.
2. Once you have made your selection, in the case of text, notice that it remains highlighted
3. You can now right click on your selection and select Copy OR Press [Ctrl ]+ [C].
4. Now you have copied the material and you can use it to paste into another application...
Cut/Copy/Paste
• Once you have copied the item, go to the application where you would like to paste it.
• Place your cursor where you want to paste the item in the document (a word file, email, etc.)
• Right Click and then select Paste OR Press [Ctrl]+[V].

Windows Terminology Here are a few important terms that you must know to be able to understand the rest of the information on this page.
Desktop The entire screen, which contains the Task Bar, Icons, and Windows.
Task Bar The horizontal bar that appears at the bottom of the Desktop. It always contains the Start Button and buttons for any minimized applications.
Window
Control

A control on the top right part of a Window that affects its size.

  • _ Minimize: Show window only on the Task Bar
  • [] Maximize/Midimize: Window fills/is-in Desktop
  • X Terminate: discard the window
    If a window is minimized, click it on the task bar and it will open and move to the desktop. When a window on the desktop is maximized, it fills the entire screen; when such a screen-filling window is midimized, it returns to its original desktop size.
  • Context
    Menu
    Right Clicking on Windows, buttons, or Icons brings up a small window containing a list of operations; the user can select which operation (from the list) to perform by clicking it.

    Logging On The following instructions are for logging onto any machine running Windows XP in CMU's Clusters. When you arrive at a machine, you should see a Welcome to Windows box displayed.
    • Hold down the Ctrl and Alt keys and press the Del key (often written Ctrl+Alt+Delete); a Log on to Windows box will pop up.
    • In the User Name box, enter your Andrew username.
    • In the Password box, enter your Andrew password (it will appear as *'s).
    • Ensure the Log on to option box says ANDREW.CMU.EDU (Kerberos Realm); if it is showing anything else, select this option from this option box.
    • Click the button labelled OK or press the Enter/Return key.
    If you enter your username and password correctly, you will be logged on; otherwise repeat this process until you successfully logged on.

    Logging Off When you are finished working on a cluster machine, you should always log off. Before logging off, make sure to Backup all your files that contain useful information. Then ...
    • Drag and Drop all your folders/files from the desktop into the Recycle Bin icon.
    • Drag and Drop all your folders/files from c:\temp into the Recycle Bin icon.
    • Double Click the Recycle Bin icon.
    • Select File | Empty Recycle Bin.
    • Click Yes for Confirm multiple File Delete.
    To actually log off
    • Click Start and select Shutdown....
    • The What do you want the computer to do text field should show Log off username (where username is your username on Andrew); if this action is not selected, select it.
    • Click OK or press Enter/Return.
    At this point the machine will begin logging you off. To ensure that this operation is successful, you should wait until the Welcome to Windows box displayed.

    Viewing File Extensions File extensions are the the part of the file name after the period (e.g., the mcp in project.mcp or the java in Application.java). It is often very useful to be able to see both file names and extensions. On some Windows operating systems (e.g., 2000), this is the default; on others (e.g., NT) you must follow the instructions below.
    • Open an Explorer window.
    • Select View | Options...
    • Click the View tab, if it is not already visible.
    • Ensure the box labeled Hide file extensions for known types is NOT checked (click it if it is checked to toggle it to unchecked).
    • Click OK
    You should now be able to see the extensions of all files.

    Renaming Folders and Files To rename a folder or file (if it is a file with an extension, the extension should remain the same: you will be warned if you accidentally change it);
    • Right Click the folder or file.
    • In its context menu, click the Rename option.
    • Type the new name (and the same extension) in the highlighted blue box.
    The folder or file should now have the name that you typed.

    Enabling Scrolling in the Console Window Java programs often input/output text in the console window. If scrolling is enabled on these windows, you can look at all the text printed. On some Windows operating systems (e.g., Windows 2000), this is the default (300 lines); on others (e.g., Windows NT) you must follow the instructions below. To allow [more] scrolling in this window, so that you can see a [longer] history of all your program's input/output, perform the following steps (you may have to perform these steps each time that you log on):
    • Right Click in the header (on the top of the frame) of the Console Window.
    • Click Properties.
    • Select the Layout tab.
    • In the Screen Buffer Size section, type 1000 (or an even bigger number) into the Height text field.
    • Click OK.
    • On the Apply Properties window, check the bullet marked Save properties for future windows with same title.
    • Click OK.
    The console window should now be scrollable (you should see the scrolling tab along the right border of the window)

    Zipping Files WinZip (the zipping/unzippng software) is already installed on all the computers in the cluster. If you want to install it on your own computer, follow this link to the WinZip web page to download a copy). Programming assignments must be turned in as single zip file that contains all the files inside a project folder. To zip all the files in a folder named F, for example, into a single zip file
    • Right Click the folder that you want to zip.
    • In its context menu, select the Add to F.zip option (note that the name of the folder, in this example F, always precedes the zip extension; do not use the more generic Add to Zip operation).
    A WinZip window will automatically appear and disappear from your screen (this might happen so fast that you do not see it). When finished you should see a new file on your desktop (or wherever the folder you zipped came from) with the same names as your folder (the folder will still be there too) and the zip file extension (so in this case, the zip file is named F.zip).

    Unzipping Files To unzip all the files in a zip file, for example F.zip
    • Right Click the zip file that you want to unzip.
    • In its context menu, select the Extract to folder C:\...F option (note that the name of the zip file, in this example F, always appears at the end of the selection).
    When finished you should see a new folder on your desktop (or wherever the folder you unzipped came from) with the same names as the zip file (the zip file will still be there too; so in this case, the folder is named F).

    Disk Operating System (DOS) (Unit III)

    1. In the 1980s or early 1990s, the operating system that shipped with most PCs was a version of the Disk Operating System (DOS) created by Microsoft: MS-DOS.
    2. MS-DOS is a disk operating system for IBM PC–compatible computers.
    3. In its day, it was easily the most popular operating system in the world. 
    4. As with any other operating system, its function is to oversee the operation of the system by providing support for executing programs, controlling I/O devices, handling errors, and providing the user interface.
    5. MS-DOS is a disk-based, single-user, single-task operating system. These qualities make it one of the easiest disk operating systems to understand.
    DOS FILES
    • The main portions of MS-DOS are the IO.SYS, MSDOS.SYS, and COMMAND.COM files.
    •  IO.SYS and MSDOS.SYS are special, hidden system files
    • The IO.SYS file moves the system’s basic I/O functions into memory and then implements the MS-DOS default control programs, referred to as device drivers, for various hardware components.
    • These include the following:
    1.  The boot disk drive
    2. The console display and keyboard
    3. The system’s time-of-day clock
    4. The parallel and serial communications port
    IO.SYS & MSDOS.SYS
     In the PC bootup sequence, the first sector of the boot disk is loaded into memory and executed. If this is the DOS boot sector, it loads the first three sectors of IO.SYS into memory and transfers control to it. IO.SYS then:
    1. Loads the rest of itself into memory.
    2. Initializes each default device driver in turn (console, disk, serial port, etc..). At this point, the default devices are available.
    3. Loads the DOS files and calls its initialization routine.
    4. Processes the MSDOS.SYS file .
    5. Processes the CONFIG.SYS file, in MS-DOS 2.0 .
    6. Loads COMMAND.COM (or other operating system shell if specified).

    COMMAND.COM 
    • The COMMAND.COM command interpreter accepts commands issued through the keyboard, or other input device, and carries them out according to the commands definition.
    •  When DOS runs an application, COMMAND.COM finds the program, loads it into memory, and then gives it control of the system. When the program is shut down, it passes control back to the command interpreter.


    Common MS-DOS Commands
    Command
    Description
    Usage
    dir
    Lists all files in current directory
    Command: C:\>dir
