This model is now fully dependent on sources of energy to continue to function. However, due to the environmental politicization and the problematization of the use of fossil sources, the search for an alternative energy model has been the subject of academic research and public policies for some years. The present work focuses on the development of a computational program that will provide the user, often unaware of the research in development, with the access and the necessary guidance for the implantation of a tubular rural biodigester. The application was developed in Java language, where the technical and economical sizing methodology used takes into account data such as the type and number of animals and the user's monthly electricity consumption. After the program processes the calculation routine, the user is presented the results in 3 different screens, one containing a generic image with the nomenclature adopted for the estimated dimensions, a screen with technical information of the design and a final screen with information of economic projection. This work is expected to disseminate and democratize alternative research and technologies through the use of digital technology. / O desenvolvimento tecnológico e econômico ocorreu através do extrativismo do meio ambiente e da industrialização em um modelo globalizado de sociedade. Esse modelo encontra-se hoje plenamente depende de fontes de energias para continuar funcionando. Entretanto, em decorrência da politização ambiental e da problematização quanto ao uso de fontes fósseis, a busca por um modelo energético alternativo tem sido tema de pesquisas acadêmicas e políticas públicas há alguns anos. O presente trabalho tem como foco o desenvolvimento de um programa computacional o qual proporcionará ao usuário, muitas vezes alheio às pesquisas em desenvolvimento, o acesso e o direcionamento necessários para a implantação de um biodigestor rural tubular, devendo ser informados apenas alguns dados bases. O aplicativo foi desenvolvido em linguagem Java, onde a metodologia de dimensionamento técnico e econômico utilizada levam em conta dados como o tipo e número de animais e o consumo mensal de energia elétrica do usuário. Após o programa processar a rotina de cálculos, é apresentado ao usuário os resultados em 3 telas diferentes, uma contendo uma imagem genérica com a nomenclatura adotada para as dimensões estimadas, uma tela com informações técnicas do dimensionamento e uma tela final com informações de projeção econômica. Espera-se com esse trabalho a difusão e a democratização de pesquisas e tecnologias alternativas através do uso da tecnologia digital.

These assessment tools are usually developed for pen and paper application. The objective of the present study was to investigate the feasibility of a computer administered test battery (BALES) for assessment of reading, writing skills and sign language familiarity through: correlation between the tests, comparison of the scores between grades and pen and pencil application. The subjects were 44 deaf students of the 1st and 2 nd grade of the cycle II, of the three Basic School from the Great São Paulo. The computer based version of BALES with 11 tests was administered: The Word Reading Test (WRT); the Sentence Reading Test (SRT1.1); the Choice Picture Naming Test (CPNT 1.1); the Written Picture Naming Test (WPNT 1.1); the Choice Picture Naming Test (CPNT 2.1); the Written Picture Naming Test (WPNT 2.1); the Written Word Choice Libra Naming Test (WWCLNT 1.1); the Written Libra Naming Test (WLNT 1.1); the choice Libra Naming Test (CLNT 2.1); The Written Libra Naming Test (WLNT 1.1); the Choice Libra Naming Test (CLNT 2.1); the Written Libra Naming Test (WLNT 2.1); the Libra Vocabulary Test (LVT 1.1). The results showed a high correlation for 10 tests but one (LVT) with low correlation. The comparison of subjects scores with the school grade factor showed no significant difference between the two compared grades in computer application, which was coherent with in the pen and paper application results. Additionally, the means of right responses in each test f the battery were similar to those found in the pen and paper application. Results proved the possibility of BALES-on line battery, as a useful assessment tool for reading, writing and sign language (LIBRA) evaluation. / O desenvolvimento de instrumentos para avaliação cognitiva de escolares surdos brasileiros tem possibilitado a compreensão das habilidades de leitura, escrita, vocabulário e de língua de sinais brasileiros (LIBRAS). Tais instrumentos tradicionalmente são desenvolvidos para serem aplicados na forma de papel e lápis. A presente dissertação teve por objetivo verificar a viabilidade de uma bateria computadorizada de avaliação de leitura, escrita e conhecimento de língua de sinais (BALES) por meio de: correlação entre os testes que compõe a bateria, comparação entre as séries escolares e com os dados obtidos na aplicação tradicional. Foram avaliados 44 em surdos do 1° e 2° ano do ciclo II, do Ensino Fundamental de 3 escolas públicas da Grande São Paulo. Foi aplicada a versão computadorizada da BALES, que era composta de 11 testes: Teste de Competência de Leitura de Palavras (TCLP 1.1); Teste de Competência de Leitura de Sentenças (TCLS 1.1); Teste de Nomeação de Figuras por escolha (TNF 1.1); Teste de Nomeação de Figuras por escrita (TNF 1.1); Teste de nomeação de figuras por escolha (TNF 2.1); Teste de nomeação de figuras por escrita (TNF 2.1); Teste de nomeação de sinais por escolha de palavras escritas (TNS 1.1); Teste de nomeação de sinais por escrita (TNS 1.1); Teste de nomeação de sinais por escolha (TNS 2.1); Teste de nomeação de sinais por escrita (TNS 2.1); Teste de Vocabulário Receptivo de Sinais da Libras (TVRSL 1.1). Resultados mostraram correlações positivas entre 10 testes que compõem a bateria, sendo que o único teste que apresentou baixas correlações com os demais foi o TVRSL. A comparação do desempenho dos sujeitos em função da série escolar revelou não haver diferenças significativas entre as duas séries avaliadas através dos testes computadorizados, esta ausência de diferença também foi observada na verão lápis e papel. Por fim, os valores médios de acertos nos teste que compõe a bateria foram muito semelhantes aqueles obtidos através da avaliação tradicional. Os dados encontrados mostram a viabilidade da BALES-on line como instrumento de avaliação de habilidades de leitura, escrita e conhecimento de sinais da LIBRAS.

In this study, I investigated the interactions between multiple intelligences and performance of learners in open-ended digital learning tasks, and to suggest possible approaches to the teaching and learning process using computers in Tanzania. With the current introduction of computers in the education system in Tanzania, the qualities of instruction and learner participation in learning computer application skills and achievement have not necessarily shown improvement (Nelson, Post,&Bickel, 2003; Tilya, 2003). It is imperative for computer teachers to know the pedagogical strategies that can help them use the current technology effectively. Researchers in instructional design have suggested instructional methods that incorporate methods that encourage the use of learner-centered instruction, incorporating activity oriented methods, and problem solving that are designed around real-world problems (Huba&Freed, 2000). Learners will be able use their knowledge effectively, reveal their uniqueness as learners, and learn computer application skills in a social setting (Gardner, 1983; Wiggins, 1993, 1998; Teele, 2000; Huba&Freed, 2000). The theory of multiple intelligences by Howard Gardner (1983) was used as the theoretical framework for this study. The theory postulates that that everybody has at least eight intelligences which reflect different ways of interacting with the world. In an effort to achieve quality learning, learning must be based on multiple approaches with a series of activities which are authentic in nature and have to be completed by the learners. The study was conducted in Tanzania using a qualitative research design. Four secondary schools were selected and 40 learners doing computer studies course participated in the study. Four intelligences from the theory of multiple intelligences were assessed: logic-mathematical, verbal-linguistic, visual-spatial and interpersonal intelligences. Assessment was done using performance assessment procedures. The findings indicated that there are distinctive intelligence profiles apart from the four intelligences that were investigated in this study. Despite the intelligence profiles of the learners, didactical issues that will enhance ICT adoption in the education environment are important. These include the use of authentic tasks, performance assessment to acknowledge learners unique performance abilities across several intelligences and teachers familiarization in the use of performance assessment procedures. / Thesis (PhD (Curriculum Studies))--University of Pretoria, 2008. / Curriculum Studies / unrestricted

A Pipeline Analytical Program and Dredging Knowledge{Base Expert{System (DKBES) determines a pipeline dredge's production and resulting cost and schedule. Pipeline dredge engineering presents a complex and dynamic process necessary to maintain navigable waterways. Dredge engineers use pipeline engineering and slurry transport principles to determine the production rate of a pipeline dredge system. Engineers then use cost engineering factors to determine the expense of the dredge project. Previous work in engineering incorporated an object{oriented expert{system to determine cost and scheduling of mid{rise building construction where data objects represent the fundamental elements of the construction process within the program execution. A previously developed dredge cost estimating spreadsheet program which uses hydraulic engineering and slurry transport principles determines the performance metrics of a dredge pump and pipeline system. This study focuses on combining hydraulic analysis with the functionality of an expert{system to determine the performance metrics of a dredge pump and pipeline system and its resulting schedule. Field data from the U.S. Army Corps of Engineers pipeline dredge, Goetz, and several contract daily dredge reports show how accurately the DKBES can predict pipeline dredge production. Real{time dredge instrumentation data from the Goetz compares the accuracy of the Pipeline Analytical Program to actual dredge operation. Comparison of the Pipeline Analytical Program to pipeline daily dredge reports shows how accurately the Pipeline Analytical Program can predict a dredge project's schedule over several months. Both of these comparisons determine the accuracy and validity of the Pipeline Analytical Program and DKBES as they calculate the performance metrics of the pipeline dredge project. The results of the study determined that the Pipeline Analytical Program compared closely to the Goetz eld data where only pump and pipeline hydraulics a ected the dredge production. Results from the dredge projects determined the Pipeline Analytical Program underestimated actual long{term dredge production. Study results identi ed key similarities and di erences between the DKBES and spreadsheet program in terms of cost and scheduling. The study then draws conclusions based on these ndings and o ers recommendations for further use.

The Information Technology (IT) as subject taught in South African secondary schools is considered to be a very perplexing subject. The IT as a subject has four learning outcomes which are E-Communication (weight 10%), Social and Ethical Issues (weight 10%), Hardware and Systems Software (weight 20%) and Programming and Software Development (weight 60%). The Programming and Software Development enjoys the highest weight as outcome of IT and it is believed to be the main cause of the difficulty of IT. The number of Grade 9 learners willing to offer IT as a subject in Grade 10 is decreasing and the number of learners pursuing IT until Grade 12 is declining in every school in South Africa annually. The aim of this research is to investigate methods that enhance teaching and learning Information Technology at a selected high school focusing on Grade12 learners. Although this work investigated many teaching and learning methods, it has come to be known that the hybrid system or method is the best to adopt and apply in teaching and learning of IT in high schools especially in the relevant target high school. Thirty (30) participants were sampled. Three (3) data collection instruments, which were questionnaires, interviews and observations were used. Results that were obtained from the use of these data collection instruments were recorded and analysed. Results from these instruments were compared and conclusions drawn. A major finding was that the hybrid system that combines both teacher-centered and learner-centered teaching approaches was able to enhance the teaching and learning of IT. / Science and Technology Education / M.
