.Microsoft then hosts focus group sessions, typically in Redmond, Washington, with these industryexperts to determine how the technologies are used.These sessions do not focus on features only.The sessions are designed to extract product-usage scenarios from these experts on how they use thetechnology, regardless of feature sets, in the real world.Obviously, there must be a focus on the newaspects of the software, or the exam becomes a rehash of the previous version.Things to Know About the Test 9X'The exam prep guide is the output of this focus group well, sort of.The prep guide structure isexplained a bit later in the section that details the objectives that this exam will test on, but fornow, just know that the prep guide is the result of the focus group.The information taken fromthe focus group is formulated into the exam design document that gets a further validation pass bymore industry experts.This validation step is known as a blueprinting process, where other indus-try experts who have never seen the list before and who did not participate in the focus group canlook at each outlined objective and rate it based on relevancy, importance, and frequency.Thesevalues are fed into a spreadsheet that executes some magical psychometric formulas that spit outthe number of required exam questions for each objective to appropriately measure the candidate sknowledge on the test.After the blueprinting is complete and the data is assembled, the exam ques-tion writing can begin.Note that as of the writing of this book, the exam questions are still in mul-tiple choice or true/false format.Some newer items are being tested that consist of drag-and-drop orchoosing code segments, but the bulk of the questions are multiple choice.NOTE Microsoft is committed to moving to a performance-based testing envi-ronment for all its certifications at some point.There are many hurdles to over-come before it is a reality, but that will change the face of Microsoft certificationsconsiderably.How Questions Are WrittenJust how do the questions get written? Microsoft Learning works with various partners to createthe content for the exams in a clear process that is guided and overseen by the Product Planners, theContent Development Managers, and the Project Managers at Microsoft.Taking the exam design document and the blueprint values, a team of item writers is assembledto begin the process.These item writers must be industry experts as well, who work with thetechnology on a daily basis.They receive training on effective exam question writing.This might sound a little strange at first.You may be saying to yourself, Why would you needto have training on how to write a test question? If you know the technology, you can write a testquestion on it.Although there is some truth to that thought, writing an effective exam question is not always aneasy task.Here are the reasons why:�'�'The question must test the objective it maps to.�'�'The question must be worded in a technically accurate and correct form.�'�'Slang or nicknames cannot be used.(An example of this is in the IT world where in NorthAmerica the acronym DMZ has been used to represent the perimeter network for securitypurposes.In certain other countries, DMZ has negative connotations.)�'�'Wording and terms must take into account translation into other languages.10 CHAPTER 1 INTRODUCING THE PROGRAMMING C# CERTIFICATIONX'�'�'Each question must be legally defensible.That is to say, if the question is asking for one answer,there can be only one correct answer among the available answer choices.All other answersmust be 100 percent incorrect.�'�'The writer cannot make up technologies or answers that do not exist in the product just toprovide a wrong answer.�'�'Questions cannot be tricky with subtle wording that hides clues.�'�'Questions cannot be simply recall questions where a candidate would normally look up theanswer in MSDN or use IntelliSense.An example would be writing a question that tests theorder of parameters for a method call for a class in the base class library.�'�'One question on the exam cannot give away the answer to another question on the exam.�'�'Questions must be written to the correct cognitive level.As you can see, there are quite a few rules involved in the acceptance criteria for the questions.Mostwriters think they will turn out their questions with minimal trouble because they know the technologyso well, but they soon find out that good exam questions take hard work and careful thought.After the questions have been written, the next formal part of the process is to hold an Alpha ses-sion.The Alpha session typically involves the lead item writer plus six to eight more subject matterexperts who go over each written question [ Pobierz całość w formacie PDF ]
