unique challenges First, the test takers may nd preparation for the test a problem given the variation in tasks In addition, since the open-ended exercises allow candidates to consider and incorporate a wider range of practical information in their responses, response time can be lengthy, resulting in limited numbers of tasks within a given period of time Further, the amount of time required to respond can vary dramatically across exercises In the worst case, the response information collected from the test taker is too sparse to produce a reliable score These assessment tasks, while they have substantial relevance to practice, limit the breadth of content that can be covered in a given amount of time, thus threatening the generalizability of the interpretation of the results and the comparability of scores across examinees In addition to the variability in content and item type current test development procedures often do not constrain examinee responses suf ciently to prevent test takers from providing unique and unexpected, but correct, responses The creative test developer may not (and probably can not) envision every behavior candidates will evince These issues might be viewed as a natural tension between the need to present realistic exhibits, and the desire to collect as much pertinent response data as possible from the candidate in a restricted time period However, responses to realistically complex tasks can lead to a need to engage in lengthy, error-prone manual review of large numbers of unanticipated responses to tasks An emerging alternative, described elsewhere in this volume ( 5), is that of principled design A principled design process is intended to focus the test developer s creativity on the key assessment goals of an exercise while limiting the introduction of irrelevant variation in the tasks Principled design begins by considering the interpretation of the score and keeps that perspective paramount in task design and content development A series of questions illustrates how the sequence of the development process would be changed from the standard blueprint-based approach: What conclusions do I want to draw about the est taker s knowledge and skills What would constitute evidence that the test taker has or does not have that knowledge and skill Can I ask the test takers to give an answer or perform a task that would require them to provide the evidence I seek What static and/or interactive information will the candidate require (eg description of client or patient situation, relevant nancial or medical information, etc) What tools (eg spreadsheet, word processor, and calculator) are required for the candidate to provide the information and how robust do these tools need to be Is there any non-relevant knowledge or skill required to answer the question or perform the task Can I develop many different questions to measure this task that are equivalent .

Do the questions provide suf cient information for the time it takes the test taker to respond, and leave time so that I can ask more questions to ensure con dence in the decision made using their scores Can I evaluate the responses consistently, quickly, and accurately By following the principled design sequence, test developers become more than subject matter experts They now participate in the realm of test engineers and software architects The answers to the questions above should provide the speci cations for assessment task design Among the speci cations that can result from a principled design are the tools (exhibits, calculators, spreadsheets, word processors, search engines, etc) that need to be available to the test taker to provide the necessary information, limitations on the length of the task based on the amount of information to be generated from it, the range, breadth, and depth of content that is appropriate for the task, and the rubrics, keys, and rules to evaluate of the response (single key, lists of acceptable keys, algorithms, etc) In other words, principled design will produce assessment templates that both enable and constrain test development A principled design can also provide standardized speci cations for the tools For example, there may be suf cient overlap across different nancial situations that several entire classes of tasks can all be supported by one, two, or three standard spreadsheet templates Properly designed, these templates would be large enough to allow the creation of useful measurement tasks, but would ensure that the test developer does not introduce unnecessary and time-consuming complexity into the task Bene ts from this design process should be decreased complexity of task development, increased quality and consistency across tasks, which aids both the developers and the candidates, known task characteristics (eg unidimensional or multidimensional), known response characteristics, comprehensive scoring speci cations, and reduced costs of both development and scoring An important intended longer-term bene t from a rigorous principled design is the development of tasks with known statistical properties Once the features of the task have been stabilized and the essential format of the item or task has been administered to test takers, the empirical dif culty of scored elements can be estimated An example of the usefulness of collateral information in the prediction of statistical properties of new items is available from Keller (2002) These estimates could be useful in scoring (or calibration with smaller samples) when new tasks are based on the same template Such a result would dramatically reduce the time between the development of a task and its use in an operational test (by eliminating the need for pretesting or post-administration analyses) and allow faster scoring and reporting Additional bene ts of a principled design include automated, or semiautomated, task generation and review, thus further reducing development time and xpense (see, eg, Brittingham et al, 2000) In order to meet consumer needs, performance exercises of the future will need to measure a combination of skills and content, be template based, and.

QR Code Drawer In Visual C# Using Barcode drawer for VS NET Control to generate, create QR Code In the example CSS3 external style sheet, the width is set o 480 with the code max-width:480px; for an iPhone with 480-pixel horizontal resolution However, when you run the application on your mobile device, the text may be way too big or way too small What s going on We tend to think of screen resolution in terms of the number of pixels the more pixels, the higher the resolution So, if you set your screen to 1680 x 1050, it has a higher resolution than if I set it to 1024 x 768 However, the resolution actually depends on the number of pixels relative to the size of the display area.

More important than the number of pixels is the number of pixels stuffed into your viewing area or pixels per inch (PPI) pixel density If you develop your Web page on a typical computer screen, the pixel density is around 100 However, your mobile device is likely to have a much higher pixel density For example, my iPhone 3GS has a pixel density of 132 and a resolution of 480 x 320 If I upgrade to an iPhone 4, my pixel density will be 326 and the resolution will be 960 x 640 However, the phones both have a 31 2-inch viewing area The iPhone 4 s resolution is double that of the iPhone 3GS, and its ppi is about 21 2 times greater.
