Atividades de modelagem exploratória aplicada ao ensino de física moderna com a utilização do objeto de aprendizagem pato quântico

This paper presents results related to the development of activities of applied exploratory modelling to Quantum Physics Teaching by using use of the learning object (LO) called the Quantum Duck. The LO is a metaphor to the photoelectric effect and it makes possible the calculation of the constant of Planck. A study was done through an experiment with High School students. As a result, it was noticed that the construction or manipulation of a model does not depend exclusively of the assimilation of the employed logic in the tool computacional, but of the understanding of the the physical phenomenon and their abilities in relating it to the aim of the developed activity.

Evaluating the students' perception of the teaching effectiveness in a teleinformatics engineering

This paper intends to present a case of computer-aided statistical analysis of teaching effectiveness in an engineering course. Due to the large amount of data generated, the computer aid becomes essential for the correct handling of data. Ratings are extremely important to the improvement of educational institutions. This study aims to provide feedback to teachers of the course that have been evaluated using the point of view of students. This research was conducted using a questionnaire, which was applied to students who had already completed the first year of the teleinformatics engineering course. The instrument allow us to observe data that, clearly indicates certain subjective characteristics. The automation of the analysis process is a crucial step in the interpretation of the results. Our results deserve consideration for the improvement of teaching in an engineering course.

A pesquisa foi realizada numa escola da rede municipal de ensino de Fortaleza, com alunos do 7o ano. Os dados apresentados compoem os foruns de discussao realizados durante o projeto A Arte pela Arte. Dentre os resultados, enfoca-se a interacao constante, a aprendizagem colaborativa e o uso intensivo dos recursos tecnologicos. Tais dados indicam que trabalhar com projetos tendo o SOCRATES como suporte constitui-se em alternativa viavel para a dinamizacao da Arte como disciplina dos curriculos. Abstract: The study investigated a project-based approach for art teaching with support of a virtual environment called SOCRATES. The research was conducted in a public school in Fortaleza with 7th grade students. Data was composed of messages from the SOCRATES forum during a Project called “Art by Art”. Results indicate the presence of constant students’ interaction, collaborative learning and intensive use of technological resources. Such data indicate that the project based approach, supported by SOCRATES, is a viable alternative to promote Arts as a discipline in school curriculum.

Climate change impacts on water demand and availability using CMIP5 models in the Jaguaribe basin, semi-arid Brazil

The objective of this study was to analyze climate change impacts on irrigation water demand and availability in the Jaguaribe River basin, Brazil. For northeastern Brazil, five global circulation models were selected using a rainfall seasonal evaluation screening technique from the Intergovernmental Panel on Climate Change named Coupled Model Intercomparison Project Phase 5. The climate variables were generated for the base period of 1971–2000, as were projections for the 2025–2055 future time slice. Removal of maximum and minimum temperature and rainfall output bias was used to estimate reference evapotranspiration, irrigation water needs, and river flow using the rainfall—river flow hydrological model Soil Moisture Accounting Procedure for the baseline and future climate (Representative Concentration Pathways 4.5 and 8.5 scenarios). In addition, by applying improved irrigation efficiency, a scenario was evaluated in comparison with field observed performance. The water-deficit index was used as a water availability performance indicator. Future climate projections by all five models resulted in increases in future reference evapotranspiration (2.3–6.3%) and irrigation water needs (2.8–16.7%) for all scenarios. Regarding rainfall projections, both positive (4.8–12.5%) and negative (− 2.3 to − 15.2%) signals were observed. Most models and scenarios project that annual river flow will decrease. Lower future water availability was detected by the less positive water-deficit index. Improved irrigation efficiency is a key measure for the adaptation to higher future levels of water demand, as climate change impacts could be compensated by gains in irrigation efficiency (water demand changes varying from − 1.7 to − 35.2%).

QEOn Questionnaire for Assessing Experiences in Virtual Learning Environments

This work aims to validate a quality assessment tool for online courses. The validation of the Online Education Quality questionnaire was performed by the Exploratory Factor Analysis to obtain possible groupings of statements that have similar statistical patterns. In total, 471 teachers responded the request to participate in the survey. Were used, as construct validation criteria, the KMO and Bartllet tests, and also the reliability test of generated clusters (Cronbachs alpha). Five components were extracted, explaining ~ 69% of the total data variance. With the extraction of these components may be considered so that the instrument is capable of generating five indicators related to quality of online education.

The Context and Outcomes of Learning in Educational Evaluation An Engineering Course

This paper presents research on educational assessment that takes into account the relationship between the context of learning and the performance obtained by stu-before in areas of knowledge of an undergraduate degree in engineering. For data analysis, the mathematical technique called multivariate PCA was used. The results indicate that in most areas of technological knowledge and professional practice, the enthusiasm and the dynamism of the teacher can facilitate student learning, however, in more scientific and theoretical areas, assessments and activities may not be suitable and favor the occurrence dropout and retention.

Uma Análise do Uso de Objetos de Aprendizagem como Ferramenta de Modelagem Exploratória Aplicada ao Ensino de Física Quântica

Resumo: Este trabalho avalia as iniciativas de combate a brecha digital por meio da introducao de computadores e do acesso a internet nas escolas da rede publica de ensino fundamental das cidades medias fluminenses. A analise divide o processo de informatizacao em tres estagios: a aquisicao de computadores , a implantacao de laboratorios de informatica e o acesso a internet com objetivo de identificar em que estagio se encontramos municipios em estudo. Abstract: This paper aimed at the medium size cities in Rio de Janeiro and their politics to control the digital divide through the introduction of computers and Internet on public schools. The analysis divided this process in three different stages from the acquisition of computers to Internet access. The appraisal pointed out the necessity of public policies to overcome the stages as the majority of these cities are still acquiring computers instead of implementing Internet access and combating the digital divide.
