Maria-Jesus Martinez-Argüelles et al. generation of personalized feedback. Moreover, it must be considered that this is directly related to the size of the group. Over 40 students, timely-costs in the elaboration of feedback go far beyond the time teachers must dedicate to it. This forces us to opt for several strategies. Reducing the number of people in the classroom leading to an optimal size could be an example, or also cost-reducing strategies can be raised, starting with the creation of generic messages (oriented to solve concrete doubts and errors which are common to several students). 50,0 45,0 40,0 35,0 30,0 25,0 20,0 15,0 10,0 5,0 0,0 Training, Multimedia personalised feedback Correction Multimedia implementation Personalized feedback 01.520 01.500 01.508 01.501 01.510 Figure 1: Hours destined to correction and personalized feedback, by type of work (ource: Own elaboration from surveys to teachers). One element that has not been taken into account when implementing the pilot test and could add some significant distortion to the analysis is the fact that in the subject Statistics Essentials there was, at the same time, another pilot test incorporating important changes to the structure of the student's classroom being carried out. This fact reduced our frame of reference to work with when making the comparison. That is to say, whereas comparison between classrooms can be analysed with no fear, comparative analysis with previous semesters is difficult because they would not be strictly comparable. Moreover, in this case, the teacher did not manage two small-sized groups but only one. 4. Conclusions Implementation of multimedia personalized feedback arises as a need to improve the student's learning capacity and performance, making the best out of generalization and spreading of multimedia tools, beyond the feedback in text. From this element and after developing a set of pilot tests in several subjects of the Degree of Business Administration the following conclusions can be drawn: Firstly, with the aim to make multimedia feedback more efficient and to make the best of its options, teachers need specific training both technological and pedagogical, as well as to develop communication abilities through video. Secondly, it has been proved that personalized feedback requires an important time investment by the teacher, therefore it is necessary to plan the intensity and frequency in which inputs will take place both regarding students and PACs. Thirdly, the effectiveness of feedback and accuracy of using one or another channel, one or another type of feedback depends a lot on the typology of the subject and the teachers' communication and technological abilities. Fourthly, it can be stated that personalized feedback brings a closer relationship between learner and teacher, this having favourable and encouraging effects on learning on the students. It is also certain that, on the other hand, this more personalized relationship between learner and teacher is to the detriment of the relationship classroom-group. Fifthly, it is apparent that personalization of feedback changes the way PACs are corrected and, therefore, lastly we can conclude that using other ways to give feedback different from the written one, does not reduce the 462

Maria-Jesus Martinez-Argüelles et al. teachers' dedication and makes it hard to be implemented generally in groups of 70 students with the current contractual relationship of dedication. These conclusions must be compatible with the fact that students judge very positively the personalized feedback and has a facilitating as well as motivating effect on learning. Nevertheless, according to what the teacher suggests, the most important element is what is said rather than the tool that is used to say it. On the other hand, in order for this feedback to be implemented by teachers, a technical training on communication and pedagogy is needed. This personalization requires additional dedication and new ways to correct PACs that make it difficult to be extrapolated to a 70-student classroom-group, particularly taking into account that the longer this personalized feedback takes place, the more demanding students become and the teacher-student interaction increases. Finally, from this study several lines of future investigation arise. Data analysis regarding academic performance between pilot classrooms and monitoring classrooms is a key element to be valued when considering that the academic performance of the over effort that personalized feedback means. In this sense, it must also be considered, when assessing its possible spreading to the rest of subjects within the context, whether or not different types of subjects correspond to different types of feedback.
