Welcome to Real Ex Girlfriends by Pornpros
The test has at least to make decisions about tense, person, number and spelling. But apart from the impurity of such items, there is the practical difficulty of framing them so that there is one, and only one, acceptable response. In this case both attend and aura attendu are acceptable. While each of these Real Ex Girlfriends examples is about as 'pure' as you can get, each suffers from the obvious weakness that the testee can always get 50 per cent score by guessing! Consequently for reasons of statistical validity it is usual to include a number of further choices or distractors. The skill in formulating good test items is largely one of selecting good distractors. More RealExGirlfriends at Pornpros Network The characteristics of a good distractor is that it should genuinely distract some testees, that is, that it should serve to discriminate between testees, by tempting some more than others. In other words, the distractor should not be such a serious contender for the good testee's attention that he need do more than glance at it only to dismiss it. For the middling pornpros pornstars network it must at least be a near-equal candidate for the correct answer, whilst the poor testee must fall for it. But in what way should the distractor compete with the correct response? To answer this question we have to look at the context-sentence. A good testee is one who will more or less immediately recognize from the context given him what sort of choice is being asked of him, orthographic, semantic or syntactic, and if the latter, in which category, e.g. tense, number, person, etc. He must therefore be able to dismiss out of hand the distractors, because they are of the wrong category. The Real Ex Girlfriends we have been working with falls into the shaded box in Figure 54: recognition, written, syntactic. It is not difficult to work out what form the test would take which belonged in another box. For example, a production, spoken, semantic test would be simple; the tester might ask the testee, in speech, a question like: What would you call a person who designs houses ?A recognition, written, orthographic test would be to ask a testee to underline the correctly spelled word: recomend, reccomend, recommend, reccommend. |
