Study of the impact federated erubrics on assessing competences in the practicum

Presentation Research of the Practicum and externships has a long history and involves important aspects for analysis. For example, the recent changes taking place in university grades allot more credits to the Practicum course in all grades, and the Company-University collaboration has exposed the need to study in new learning environments. The rise of ICT practices like ePortfolios, which require technological solutions and methods supported by experimentation, study and research, require particular examination due to the dynamic momentum of technological innovation. Tutoring the Practicum and externships requires remote monitoring and communication using ePortfolios, and competence-based assessment and students’ requirement to provide evidence of learning require the best tutoring methods available with ePortfolios. Among the elements of ePortfolios, eRubrics emerge as a tool for design, communication and competence-assessment. This project aims to consolidate a research line on eRubrics, already undertaken by another project -I+D+i [EDU2010-15432]- in order to expand the network of researchers and Centres of Excellence in Spain and other countries: Harvard University in USA, University of Cologne in Germany, University of Colima in Mexico, Federal University of Parana, University of Santa Catarina in Brasil, and Stockholm University in Sweden(1). This new project [EDU2013-41974-P](2) examines the impact of eRubrics on tutoring and on assessing the Practicum course and externships. Through technology, distance tutoring grants an extra dimension to human communication. New forms of teaching with technological mediation are on the rise and are highly valuable, not only for formal education but especially in both public and private sectors of non-formal education, such as occupational training, unemployed education and public servant training. Objectives Obj. 1. To analyse models of technology used in assessing learning in the Practicum of all grades at Spanish Faculties of Education. Obj. 2. To study models of learning assessment measured by eRubrics in the Practicum. Obj. 3. To analyse communication through eRubrics between students and their tutors at university and practice centres, focusing on students’ understanding of competences and evidences to be assessed in the Practicum. Obj. 4. To design assessment services and products, in order to federate companies and practice centres with training institutions. Among many other features, it has the following functions CoRubric(3) 1. The possibility to assess people, products or services by using rubrics. 2. Ipsative assessment. 3. Designing fully flexible rubrics. 4. Drafting reports and exporting results from eRubrics in a project. 5. Students and teachers talk about the evaluation and application of the criteria Methodology, Methods, Research Instruments or Sources Used The project will use techniques to collect and analyse data from two methodological approaches: 1. In order to meet the first objective, we suggest an initial exploratory descriptive study (Buendía Eisman, Colás Bravo & Hernández Pina, 1998), which involves conducting interviews with Practicum coordinators from all educational grades across Spain, as well as analysing the contents of the teaching guides used in all educational grades across Spain. 55 academic managers were interviewed from about 10 faculties of education in public universities in Spain (20%), and course guides 376 universities from 36 public institutions in Spain (72%) are analyzed. 2. In order to satisfy the second objective, 7 universities have been selected to implement the project two instruments aimed at tutors practice centers and tutors of the faculty. All instruments for collecting data were validated by experts using the Delphi method. The selection of experts had three aspects: years of professional experience, number and quality of publications in the field (Practicum, Educational Technology and Teacher Training), and self-rating of their knowledge. The resulting data was calculated using the Coefficient of Competence (Kcomp) (Martínez, Zúñiga, Sala & Meléndez, 2012). Results in all cases showed an average experience of more than 0.09 points. The two instruments of the first objective were validated during the first half of 2014-15 year, data collected during the second half. And the second objective during the first half of 2015-16 year and data collection for the second half. The set of four instruments (two for each objective 1 and 2) have the same dimensions as each of the sources (Coordinators, course guides, tutors of practice centers and faculty) as they were: a. Institution-Organization, b. Nature of internships, c. Relationship between agents, d. Management Practicum, e. Assessment. F. Technological support, g. Training and h. Assessment Ethics. Conclusions, Expected Outcomes or Findings The first results respond to Objective 1, where we find different conclusions depending on each of the six dimensions. In the case of internal regulations governing the organization and structure of the practicum, we note that most traditional degrees (Elementary and Primary grades) share common internal rules, in particular development methodology and criteria against other grades (Pedagogy and Social Education ). It is also true that the centers of practices in last cases are very different from each other and can be a public institution, a school, a company, a museum, etc. The memory with a 56.34% and 43.67% daily activities are more demands on students in all degrees, Lesson plans 28.18% 19.72% Portfolio 26.7% Didactic units and Others 32,4%. The technical support has been mainly used the platform of the University 47.89% and 57.75% Email, followed by other services and tools 9.86% and rubric platforms 1.41%. The assessment criteria are divided between formal aspects of 12.38%, Written expresión 12.38%, treatment of the subject 14.45%, methodological rigor of work 10.32%, and Level of argument Clarity and relevance of conclusions 10.32%. In general terms, we could say that there is a trend and debate between formative assessment against a accreditation. It has not yet had sufficient time to further study and confront other dimensions and sources of information. We hope to provide more analysis and conclusions in the conference date.

Reliability of Tethered Swimming Evaluation in Age Group Swimmers

The aim of the present study was to examine the reliability of tethered swimming in the evaluation of age group swimmers. The sample was composed of 8 male national level swimmers with at least 4 years of experience in competitive swimming. Each swimmer performed two 30 second maximal intensity tethered swimming tests, on separate days. Individual force-time curves were registered to assess maximum force, mean force and the mean impulse of force. Both consistency and reliability were very strong, with Cronbach’s Alpha values ranging from 0.970 to 0.995. All the applied metrics presented a very high agreement between tests, with the mean impulse of force presenting the highest. These results indicate that tethered swimming can be used to evaluate age group swimmers. Furthermore, better comprehension of the swimmers ability to effectively exert force in the water can be obtained using the impulse of force. Key words: swimming, training and testing, propulsive force, front crawl.

Intercâmbio de experiências e levantamento de demandas ergonômicas em unidades de beneficiamento de frutos do cerrado, mandioca e café em comunidades do Norte de Minas Gerais.

Este relato descreve a experiência realizada por meio de uma parceria entre o Projeto Rio Pardo, da Embrapa Cerrados e a Escola Politécnica/USP, visando inserir a questão do trabalho agrícola familiar nas ações desenvolvidas junto aos agricultores de três comunidades de Rio Pardo de Minas/MG, produtoras de frutos do cerrado, goma/farinha de mandioca e café sombreado. O objetivo foi levantar possíveis demandas ergonômicas existentes nestas unidades de produção, que estão implantando agroindústrias familiares para realizar o beneficiamento da produção. As demandas relacionam-se a problemas com a produção, a organização do trabalho e a saúde dos trabalhadores. Percebe-se a coexistência do saber tradicional, transmitido entre gerações, com a inovação em termos de maquinário e instalações. Há diversos arranjos produtivos presentes, fruto da criatividade e sabedoria aplicada dos agricultores. Estas inovações podem ser o embrião de projetos futuros de novos maquinários e arranjos produtivos. Trata-se de fazer comunicar dois saberes, dos projetistas e dos usuários, contribuindo para que estes últimos possam ser empoderados no papel de criadores de inovações, contribuindo para a incorporação de aspectos ergonômicos na evolução dos equipamentos e instalações. Abstract: This report describes the experience carried out through a partnership between Project ? Rio Pardo ?, Embrapa Cerrados/DF and the Polytechnic School of USP, in order to put the issue of family farm labor in the actions developed by farmers in three communities of Rio Pardo de Minas, north of Minas Gerais. The main products are fruits of the cerrado, cassava starch and manioc flour and shaded coffee. The initial goal was to raise possible these existing ergonomic demands of family farming units, which are in the process of implementation of family agri-industries to undertake the processing and beneficiation production. The ergonomic demands are related to production problems with the organization of work and the health of farm workers. In preliminary analyzes, it was possible to perceive the coexistence of traditional knowledge transmitted between generations, with innovation in terms of machinery and facilities. There are several productive arrangements, result of creativity and knowledge of farmers. These innovations, developed by who performs the work, may be the starting point for future designs of new machinery and productive arrangements. It could demonstrated the importance of communication between two knowledge, from the designers and from the users (farmers), contributing to the latter to be empowered in their role as creators of innovation and contributing to the incorporation of ergonomic aspects in the context of setting up their equipment.
