Because of this, there are student support tools, such as online assessment systems. In this work we will present the results of the simulation of an online assessment made by a student with a given proficiency, in order to collect all data regarding the performance of this student &#8211; his final grade &#8211; using the Item Response theory in two approaches to calculate the final grade. A first approach using the question subsequent to an answer from a higher or lower level of difficulty depending on the correctness of the previous question. And a second using the question subsequent to an answer of a level of difficulty between the previous and the maximum or minimum limit depending on the correctness of the previous question. Simulation results were analyzed for different sizes of tests and for different proficiencies of the simulated respondents. After multivariate analysis of clustering of results by K-means, it appears that both approaches are suboptimal for different situations of test sizes in the search for the final grade closest to the simulated proficiency.<\/p>\n\n\n\n<p> &lt; Baixe o artigo clicando abaixo &gt; <\/p>\n\n\n\n<div class=\"wp-block-file\"><a id=\"wp-block-file--media-936d0963-a1f2-4477-9aea-ebe59b8fa09d\" href=\"https:\/\/leonardoguedes.com.br\/lg\/wp-content\/uploads\/2020\/03\/7418-19776-1-PB.pdf\">7418-19776-1-PB<\/a><a href=\"https:\/\/leonardoguedes.com.br\/lg\/wp-content\/uploads\/2020\/03\/7418-19776-1-PB.pdf\" class=\"wp-block-file__button wp-element-button\" download aria-describedby=\"wp-block-file--media-936d0963-a1f2-4477-9aea-ebe59b8fa09d\">Descarregar<\/a><\/div>\n\n\n\n<p>DOI:&nbsp;<a href=\"https:\/\/doi.org\/10.34117\/bjdv6n3-077\">https:\/\/doi.org\/10.34117\/bjdv6n3-077<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Authors: Leonardo Guerra de Rezende Guedes, Heitor Melo de Lucas Brand\u00e3o, Oleg\u00e1rio Corr\u00eaa Silva Neto, Eug\u00eanio J\u00falio Messala C\u00e2ndido Carvalho A evolu\u00e7\u00e3o da Internet e sua ado\u00e7\u00e3o t\u00eam transformado e continuam a transformar cada vez mais o contexto humano, e a educa\u00e7\u00e3o tamb\u00e9m est\u00e1 inserida nessa situa\u00e7\u00e3o.
