Uma perspectiva de extens?o do modelo de aceita??o de tecnologia para explicar o uso de linguagens de desenvolvimento WEB: pesquisa com desenvolvedores Pyton e Java / An extension perspective of the technology acceptance model to explain the use of web development languages: a research on Python and Java developers

No. of bitstreams: 1 IdelmarciaDO.pdf: 781272 bytes, checksum: fb2e5ba3247ab47eff60bb3c30b07e21 (MD5) Previous issue date: 2007-10-19 / The spread of the Web boosted the dissemination of Information Systems (IS) based on the Web. In order to support the implementation of these systems, several technologies came up or evolved with this purpose, namely the programming languages. The Technology Acceptance Model TAM (Davis, 1986) was conceived aiming to evaluate the acceptance/use of information technologies by their users. A lot of studies and many applications have used the TAM, however, in the literature it was not found a mention of the use of such model related to the use of programming languages. This study aims to investigate which factors influence the use of programming languages on the development of Web systems by their developers, applying an extension of the TAM, proposed in this work. To do so, a research was done with Web developers in two Yahoo groups: java-br and python-brasil, where 26 Java questionnaires and 39 Python questionnaires were fully answered. The questionnaire had general questions and questions which measured intrinsic and extrinsic factors of the programming languages, the perceived usefulness, the perceived ease of use, the attitude toward the using and the programming language use. Most of the respondents were men, graduate, between 20 and 30 years old, working in the southeast and south regions. The research was descriptive in the sense of its objectives. Statistical tools, descriptive statistics, main components and linear regression analysis were used for the data analysis. The foremost research results were: Java and Python have machine independence, extensibility, generality and reliability; Java and Python are more used by corporations and international organizations than supported by the government or educational institutions; there are more Java programmers than Python programmers; the perceived usefulness is influenced by the perceived ease of use; the generality and the extensibility are intrinsic factors of programming languages which influence the perceived ease of use; the perceived ease of use influences the attitude toward the using of the programming language / A difus?o da Web impulsionou a dissemina??o de Sistemas de Informa??o (SI) baseados na Web. Para apoiar a implementa??o desses sistemas, diversas tecnologias surgiram ou evolu?ram com este prop?sito, dentre elas as linguagens de programa??o. O Modelo de Aceita??o de Tecnologia - TAM (Davis, 1986) foi concebido com o intuito de avaliar a aceita??o/uso de tecnologias da informa??o por seus usu?rios. V?rios estudos e aplica??es diversas t?m utilizado o TAM, no entanto, n?o foi encontrada na literatura men??o a utiliza??o de tal modelo com rela??o ao uso de linguagens de programa??o. Este estudo objetiva investigar que fatores influenciam o uso de linguagens de programa??o utilizadas no desenvolvimento de sistemas Web por parte de seus desenvolvedores, utilizando uma extens?o do TAM, proposta neste estudo. Para tanto, foi realizada uma pesquisa com desenvolvedores Web pertencentes a dois grupos do Yahoo: java-br e python-brasil, no qual foram respondidos, na ?ntegra, 26 question?rios Java e 39 Python. O question?rio tinha quest?es de car?ter geral e quest?es que mediam os fatores intr?nsecos e extr?nsecos das linguagens de programa??o, a utilidade percebida, a facilidade de uso percebida, a atitude sobre o uso e o uso da linguagem de programa??o. A maioria dos respondentes eram homens, com n?vel superior, idade entre 20 e 30 anos, atuando nas regi?es sudeste e sul. Do ponto de vista de seus objetivos, a pesquisa foi descritiva. Em rela??o ? forma de abordagem, quantitativa. Para a an?lise de dados foram utilizadas ferramentas estat?sticas, estat?stica descritiva, componentes principais e an?lise de regress?o linear m?ltipla. Os principais resultados da pesquisa foram: Java e Python possuem independ?ncia de m?quina, extensibilidade, generalidade e confian?a; Java e Python s?o mais utilizadas por corpora??es e organiza??es internacionais do que apoiadas pelo governo ou institui??es de ensino; h? mais programadores Java do que Python; a utilidade percebida ? influenciada pela facilidade de uso percebida; a generalidade e a extensibilidade s?o fatores intr?nsecos as linguagens de programa??o que influenciam a facilidade de uso percebida; a facilidade de uso percebida influencia a atitude em rela??o ao uso da linguagem de programa??o
