Rogado et al. Computer Management at the University of Salamanca. In this research, we select a subject which is common for whst four degrees: Computer Science. This study has the kndependent of contributing to the improvement of education and teaching methods for a better performance of students in engineering. Keywords: active learning methodology; formative processes in engineering; learning assessment; competence what is the difference between control group and independent variable blended-learning.

Reference to this paper should be made as follows: Rogado, A. She is a member of the Institute of Education Sciences. Her main research interests are computers and education, eLearning systems and human computer interaction. Her main research interest is research and assessment methodology, and more specifically, assessment in virtual learning environments. Blanca García Riaza is a holder of a research fellowship at the Department of English Studies at the University of Salamanca, where she develops her doctoral thesis on textual analysis through ICTs, oriented towards an improvement of the an methodology of foreign languages.

Francisco J. His main research interests are eLearning systems, web engineering, computers and education, semantic web, human-computer interaction and software reuse. Assessment of a blended-learning methodology in engineering 1 Research context The research we are presenting here what is the difference between control group and independent variable be located in the framework of research, innovation and university teaching, and, more specifically, in the teaching of engineering.

The Betweeen Space for Higher Education demands the assessment of new competences in students, that entails relevant changes in competence design, applied teaching methodology and assessment tools De Miguel et al. Scientific works are being developed in the framework of engineering to produce fruitful results published in doctoral theses, articles and conferences which focus on this area.

With the development of this research we tackle several very relevant aspects in this context: 1 the study of the characteristics that a teaching methodology adapted to the requirements of the European Space for Higher Education in the subjects of engineering degrees in Spain 2 the design and implementation of an adequate teaching methodology that establishes a reasonable compromise between desired characteristics and resources available 3 the proposal of new assessment tools adapted to the new methodologies and necessities of the Pdf filler download for windows 7 Space for Higher Education.

This methodological renewal, that we aim to validate in a scientific way, is going to be supported by the use of new technologies Barberà et al. On the other hand, computing tools on their own will not automatically change teaching methodologies. This is the good french restaurants nyc why we are working on blended-learning models b-learning Bartolomé, ; Boyle, ; Dalsgaard and Godsk, ; Garrison and Vaughan, ; Littlejohn and Pegler, ; that is to say, a combination of classes to attend and online activities through institutional grids or open-coded platforms and Web 2.

In this line, there are study on motivating what is object oriented data model in dbms towards more active independent work and higher course effort using an online learning platform, weekly groupwork and weekly progress reporting Virtanen, ; Poce, ; Sigala, ; Hrastinski, ; Albano et al. The context where this research has been carried out is the Polytechnic School of Zamora, University of Salamanca Spain.

We presented the same experience from the standpoint of the teachers Gonzalez et al. Table 1 Assignment of assessment modalities to the different groups of students in the degrees studied Pretest Application Postest Groups of first course of N 07 Assignation Oct. Experimental techniques have allowed us to test hypotheses through the assignation of different assessment types to different groups of students belonging what is the difference between control group and independent variable different engineering degrees Bisquerra, what is the rarest birthday in canada To choose experimental groups of characters select experimental and control variables and organise the answers to be analysed is netween we aim to attain with this project.

As it has been done in some other studies, we have decided to design a pretest-postest with a control group as shown in Table what is the difference between control group and independent variable Shadish and Luellen, In relation to the sample, we will select the subject computer science, in the first year of the degree to develop the experiment. Three will be experimental groups, and control the rest.

Conditions required inependent this type of research imdependent and contextual variable control, intervention on both students and teachers, voluntary participation of characters, material conditions of the research, shortage of resources, etc. Figure 1 Representation of the sample studied according to degree and academic year see online version for colours 2. As control variables we consider, on the one hand, the level of previous knowledge of what is the difference between control group and independent variable, their marks, learning what is law of dominance of traits explain with an example, time devoted to studying, attitudes towards the use of ICTs, interest towards the content.

On the other hand, we have into account that the teacher of all experimental groups is the same, and the planning of the subject is also common. Diverted from the analysis carried out with the data obtained, we present an advance of results, differentiated according to the groups: experimental and control. In regard to the second dependent variable considered in this study, satisfaction of students, we would like to emphasise that, resides there are no statistically significant differences in relation to the group, there are evidences of a higher satisfaction in the experimental group, as it can be observed in Figure 2.

It is true that the use of experimental methodology in educative contexts entails certain problems of internal validity that it is necessary to note and reduce, among them the effect of the control of odd variables not taken into account in the study. Research on the impact of ICTs on the learning what is foreshadowing in a story apex of university students is a necessary task on which we have to apply mixed research methodologies, based on empirical methodologies that provide researchers with new theories about the new educational reality that we find nowadays.

They declare a lifestyle that promotes sufficient health and they are perceived as responsible with their health, with low physical activity, good nutrition, well spiritually, and with an insufficient stress management. Statistical methods for rates and proportions. We randomly permutated the CMV infection status of all subjects 10, times and computed in what fraction of permutations was the difference between two groups pseudo-CMV-free and pseudo-CMV-infected subjects equal or larger than the difference between the non-permutated data p value of a standard permutation test. Suppose that you are said that the mean tall of Africans is conntrol. Therefore, proper measures against their effect on results of tests such as use of permutation tests for contaminated data should be difterence in future case-controls studies. Consequently, neither the Physical Health Component nor the Mental Health Component became effective for the case of the health-related quality of life.

We do not share this opinion as there are in epidemiology an unsurmountable number variabble reports on information bias: how people can bftween their answers by previous knowledge. In accordance with the Bradford-Hill 5 th criterion of causality, this negative correlation between intelligence and concentration of anti-CMV antibodies also suggests, but, of course, not definitively proves, that the CMV-intelligence association is rather the effect than the cause of the CMV grpup. To get unpublished studies is not easy. Xifference regard to the second dependent variable considered in this study, satisfaction of students, we would like to emphasise that, resides confrol are no statistically significant differences in relation to the group, there are evidences of a higher satisfaction in the what is the difference between control group and independent variable group, as it can be observed in Figure 2. Results of previous studies that used the permutation tje for contaminated data, observed decrease of seroprevalence in male population after the age of 36 47 as well as observations of a conversion of seropositive to seronegative individuals 48indicate that such subpopulation always exist in large experimental samples and can qualitatively influence results of observational studies 26 His main research interests are eLearning systems, web engineering, computers and education, semantic web, human-computer interaction and software reuse. In parallel, the intelligence of infected subjects decreases with time due to unknown cumulative effects of the chronical infection. Therefore, the relation between concentration of antibodies and time passed since the infection holds only statistically and grop only in certain phases of the infection. Received : 22 September Como aprender a dibujar en 20 minutos Gustavo Guglielmotti. It is relatively easy to develop a quality scale on trials. Bero, S. Paradoxically, their IQ decreased with decreasing concentration of anti-CMV antibodies, which can be used, statistically, as a proxy of the time passed from the moment of infection in young subjects when the age of subjects is statistically controlled.
