The purpose of this study was to compare the achievement mean test scores in Technical Drawing of students enrolled for the NCE (Technical) program at the College of Science and Technology, Kaduna polytechnic, Kaduna, Nigeria. Test score means were compared between direct and remedial (preparatory) entry students and secondly among type of high school attended. Data were collected directly from students' permanent records. Two major hypotheses with three sub-hypotheses for each were tested. The first major hypothesis compared direct and remedial entry students. The second major hypothesis compared among three types of high schools attended. The One Way Analysis of variance (ANOVA) was used to analyze the data. The Duncan Multiple Comparison Test was also applied on the second major hypothesis. Both hypotheses I and II were retained at the .05 level of significance. However, hypothesis I was rejected at the .01 level of significance because the remedial entry students were found to have higher mean test scores than the direct entry students. Findings for hypothesis II indicated no significant difference among type of high school attended. It was recommended that selection for admissions for both the remedial and direct enrollments should not be based only on type of high school attended or type of subjects taken; data collected for remediation should bear directly on individuals' academic problems; and aptitude tests should be conducted in addition to transcripts currently demanded.

The purposes of the study were / to investigate the effect of type of high school on spatial ability, to investigate the relationships between students&rsquo / mathematics achievements, logical thinking abilities and their spatial abilities and to investigate the effect of technical drawing course on the development of students&rsquo / spatial abilities. The study was conducted in Ankara with 251 9th-grade students who enrolled to general, Anatolian, foreign language, commercial vocational and industrial vocational high schools. Two measuring instruments were utilized: Spatial Ability Tests and Group Test of Logical Thinking. Spatial Ability Tests, which were developed by Ekstrom, consist of card rotation, cube comparison tests measuring the spatial orientation ability and paper folding and surface development tests measuring the spatial visualization ability. The tests were translated in to Turkish by Delialioglu, (1996). Group Test of Logical Thinking was developed by Roadrangka, Yeany, and Padilla and a Turkish version of GALT was developed by Aksu, Beberoglu and Payko&ccedil / (1990). In order to analyze the obtained data, one way ANOVA, correlation analysis and t-test were used. The results of the study indicated that / there is no significant effect of type of high school on students&rsquo / spatial abilities / there is a significant positive relationship between spatial ability and mathematics achievement / there is a significant positive relationship between spatial ability and logical thinking ability / there is a significant positive relationship between spatial ability and technical drawing achievement / and there is a significant development in the students&rsquo / spatial abilities of the students in the technical drawing course.

The goal of my diploma thesisis to create a set of tasks for education at basic school. This thesis is especially focused on realization of tasks from practice.In theoretical part I deal with complex of inter-subject relations between described branches in this work, computer support, selection of 3D CAD programmes at basic school with regard to price availability and technical designing (drawing). The practical part is focused on working papers. This part allows the construction of product using the calculation of word task. This calculation makes theimage about that product easier and allows creation of model in the CAD programme and the final production. This thesis is checked up by pupils in ninth degree of basic school. The fundamental part of this work forms appendix of working papers, which are prepared for education. I consider the approachof solving the tasks for pupils at second degree of basic school to be innovative.

This environment, called Integrated Environmental Education Technical Drawing (AIEDT), was developed to integrate traditional practices with digital tools in an applied discipline of Interior Design Technology Degree in Interior Design (CSTDI) of Federal Institute of Education, Science and Technology of Paraiba (IFPB). At specific level, aims to place the picture of traditional technical drawing, technical drawing to describe the digital artifacts; show the integration of different learning environments, mapping the process of teaching technical drawing at the daily practice of teachers and students. Questioned in this work which mainly changes that may occur when using traditional technical drawing (DTT) integrated with computer aided design (CAD) requiring adaptations to their teacher's way of teaching. The hypothesis is that the teaching of DTT and CAD, embedded in a social interaction environment, provide better education and consequently the learning of graphic expression in a college course. The analytical perspective is the cultural-historical Vygotysky Lev Semenovich, where he addressed the concepts of instrumental and symbolic mediation, and social interaction in the teaching and learning. The methodological procedures were based through archival research and field research through direct observation of the practices not participating in a class of 4th period CSTDI. The instruments for data collection were interviews with teachers of subjects related to technical design, aiming to describe teaching practices and perceptions of their current teaching model; the questionnaire with students in order to verify these teaching practices; literature in books, theses, dissertations, papers and documents, in order to describe the phenomenon, its practices and tools. Our results show that the points analyzed were satisfactory in improving the teaching process. / Esta pesquisa tem como objetivo analisar a prática do ensino do desenho técnico, integrando as ferramentas tradicionais e digitais, partindo da experimentação em um ambiente integrado de nível superior. Este ambiente, chamado de Ambiente Integrado de Ensino do Desenho Técnico (AIEDT), foi desenvolvido de forma a integrar as práticas tradicionais com as ferramentas digitais aplicada em uma disciplina de Projeto de Interiores do Curso Superior de Tecnologia em Design de Interiores (CSTDI) do Instituto Federal de Educação, Ciência e Tecnologia da Paraíba (IFPB). Em nível específico, buscou-se situar o panorama do desenho técnico tradicional; descrever o desenho técnico nos artefatos digitais; mostrar a integração entre diferentes ambientes de ensino; cartografar o processo de ensino do desenho técnico na prática cotidiana de professores e alunos. Questionou-se neste trabalho, principalmente, quais as transformações que poderão ocorrer quando utilizamos o desenho técnico tradicional (DTT) integrado com o desenho assistido por computador (CAD), que exijam do professor adaptações em sua forma de ensinar. A hipótese é que o ensino do DTT e do CAD, integrados em um ambiente sócio-interacionista, proporcionará melhorias do ensino e consequentemente da aprendizagem de expressão gráfica em um curso de nível superior. A perspectiva de análise é a histórico-cultural de Lev Semenovich Vygotysky, onde se abordou os conceitos de mediação instrumental e simbólica, além da interação social no processo de ensino e aprendizagem. Os procedimentos metodológicos fundamentaram-se através de pesquisa documental e pesquisa de campo, através de observação direta não participante das práticas utilizadas em uma disciplina do 4º período do CSTDI. Os instrumentos para a coleta das informações foram a entrevista com professores de disciplinas relacionadas ao desenho técnico, com o objetivo de caracterizar as práticas docentes e a percepção de seu modelo de ensino vigente; o questionário com discentes a fim de verificar o ensino nestas práticas; pesquisa bibliográfica em livros, teses, dissertações, artigos científicos e documentos, com o objetivo de descrever o fenômeno, suas práticas e ferramentas. Os resultados desta pesquisa mostram que os pontos analisados foram satisfatórios em relação à melhoria do processo de ensino.
