diagnostic and developmental potentials of dynamic assessment for writing skill

این پایان نامه بدنبال بررسی کاربرد ارزیابی مستمر در یک محیط یادگیری زبان دوم از طریق طرح چهار سوال تحقیق زیر بود: (1) درک توانایی های فراگیران زمانیکه که از طریق برآورد عملکرد مستقل آنها امکان پذیر نباشد اما در طول جلسات ارزیابی مستمر مشخص شوند; (2) امکان تقویت توانایی های فراگیران از طریق ارزیابی مستمر; (3) سودمندی ارزیابی مستمر در هدایت آموزش فردی به سمتی که به منطقه ی تقریبی رشد افراد حساس ا...

Rate distortion performance analysis of nested sampling and coprime sampling

In this paper, rate distortion performance of nested sampling and coprime sampling is studied. It is shown that with the increasing of distortion, the data rate decreases. With these two sparse sampling algorithms, the data rate is proved to be much less than that without sparse sampling. With the increasing of sampling spacings, the data rate decreases at certain distortion, which is because w...

Normal Probability Plots and Tests for Normality

Normal probability plots are often used as an informal means of assessing the nonnormality of a set of data. One problem confronting persons inexperienced with probability plots is that considerable practice is necessary before one can learn to judge them with any degree of confidence. Some objective measure of the straightness of a probability plot would he helpful, especially for students jus...

Error Return Plots

Error-return plots show the rate of error (misunderstanding) against the rate of nonreturn (non-understanding) for Natural Language Processing systems. They are a useful visual tool for judging system performance when other measures such as recall/precision and detection-error tradeoff are less informative, specifically when a system is judged on the correctness of its responses, but may elect ...
