Live feedback systems have been proven to be suitable for teachers’ needs. Especially in classes with a lot of participants feedback in an electronic form can create additional value by getting feedback from all students. The live feedback system Tweedback incorporates three feedback possibilities. One form of feedback is Peer Instructions to test people’s knowledge using multiple choice questi...

We present an approach to designing feedback controllers that solve a path following control problem for a large class of mechanical systems. Our approach involves set stabilization via transverse feedback linearization: a coordinate and feedback transformation that yields a normal form convenient for control design making desired path attractive. Our approach also involves refining the normal ...

Compilers for functional languages, whether strict or nonstrict, typed or untyped, need to handle many of the same problems, for example thunks, lambda lifting, optimisation, garbage collection, and system interaction. Although implementation techniques are by now well understood, it remains difficult for a new functional language to exploit these techniques without either implementing a compil...

We formally characterize partial evaluation of functional programs as a normalization problem in an equational theory, and derive a type-based normalization-by-evaluation algorithm for computing normal forms in this setting. We then establish the correctness of this algorithm using a semantic argument based on Kripke logical relations. For simplicity, the results are stated for a nonstrict, pur...

The present study compared the effect of cooperative group feedback and cooperative group writing techniques in writing classes. Accordingly, 90 male and female intermediate English language learners sat for a sample piloted Preliminary English Test and 60 who scored one standard deviation above and below the mean were selected as the main participants. Both groups were taught the same course b...

this study aimed at investigating the effect of learners’ gender on their preferences for corrective feedback. learners’ prefer- ences which were investigated included the necessity, frequency, timing, type, method, and delivering agent of error treatment. to this end, a questionnaire was administered to a random sample of 100 participants (50 males and 50 females) studying english (efl) at shi...

introduction: feedback is very important in education and can help quality in the training process and orient the trainees in clinical contexts. this study aimed to assess the residents’ points of view about feedback in clinical education at shiraz university of medical sciences. methods: the sample of this study included 170 medical residents attending medical workshops in shiraz university of...

The bipolar view in preference modeling distinguishes between negative and positive preferences. Negative preferences correspond to what is rejected, considered unacceptable, while positive preferences correspond to what is desired. But what is tolerated (i.e., not rejected) is not necessarily desired. Both negative and positive preferences can be a matter of degree. Bipolar preferences can be ...

This paper describes a comparative study into the use of audio versus text as a form of feedback on student assignments. Many educational institutions currently use typewritten feedback, but developments in technology now make the provision of feedback in audio form a feasible proposition. The expansion of Higher Education has meant that creating conventional typewritten feedback can be very ti...
