Such tools allows the user to program while manipulating blocks that represent programming languages instructions. iVProg is among this class of tools and was firstly implemented in Java and could be integrated to Moodle using iAssign. Due to technological evolution, iVProg also evolved to iVProgH and its integration to Moodle is still possible by using the new version of iAssign that allow the integration of HTML stack packages to Moodle. In this paper we describe how this evolution takes place and presents iVProgH functionalities as well as iAssign extension to include HTML packages into Moodle. In addition, we give some teaching support whenever integrated using iVProgH with ...

Today, performance indicators are used to assess the quality of education. Often, these indicators are obtained through large scale tests applied by public assessment organizations, and their results contribute to the quality analysis of institutions, courses and students. To contribute to a more comprehensive educational assessment analysis, which considers the program content of the test items, we propose an automatic domain classification of exam questions and procedures to report results that allow a better comprehension of student performance based on the domain knowledge represented in the exam. The process starts by automatically classifying the test questions into knowledge domains using dictionaries. Using this classification, the mechanism separates the student’s results by domain and generates reports that give a better understanding of the test structure and studen...

However, EDM requires previous and deep knowledge of data mining methods and techniques, involving several computing paradigms, preprocessing and results' interpretation. In this paper, Moodle Predicta, an educational data mining desktop tool is presented. This software is developed in Java and enables non-expert data mining users to enjoy benefits from EDM, within the Moodle system. Divided in two modules, Moodle Predicta allows: (i) visualization of Moodle courses data; and (ii) predict students' performance.

Uma prova dessa dificuldade são os altosíndices de reprovação em disciplinas que introduzem os conceitos de algoritmo ou de uma linguagem específica. Neste artigo, apresentamos o iVProg, uma ferramenta educacional com um ambiente visual e interativo, focado no aprendizado de algoritmos e programação. Seus principais recursos incluem avaliador automático, integração com o Moodle e uma série de elementos gráficos que dispensam a codificação textual para a criação de algoritmos, deixando os estudantes livres para praticarem seu raciocínio computacional.

Numerous studies propose ways to help the early identification of students that might face difficulties and are more likely to fail a programming course. This study aims to find a correlation between their mathematical abilities and grades in an introductory computer science class following the method of a previous study that had promising results. Students were asked to answer a mathematical abilities test and had their results compared to their grades during the course using the Wilconxon-Mann-Whitney non-parametric test. The results indicate a strong correlation between mathematical abilities and programming potential.

This stored data enables extraction of valuable information using data mining. In this article, we present a systematic mapping, containing 42 papers, where data mining techniques are applied to predict students performance using Moodle data. Results show that decision trees are the most used classification approach. Furthermore, students interactions in forums are the main Moodle attribute analyzed by researchers. This systematic mapping aims to identify what type of analysis is being used to predict students' performance on Moodle, using data mining. It is organized as follows:

Exam questions are automatically classified using dictionaries that represent these themes. The mechanism then separates the student's results by theme, obtaining a grade for each theme, and generates reports that provide a better understanding of the structure of the exam and the student's outcome. A prototype has been implemented and tested with Enade Computer Science exams. The results showed the methodology allows to identify areas where students excel, and how the exam reflects the structure of the course.

But it is necessary to analyse the performance of the groups that adopt this practice and then investigate it real efficience. This paper, gives emphasis in the use of games for Computer Science higher education , through an SRL with the aim of presenting results from groups, in the latest 5 years. Were found 261 papers, in 4 search bases, from those, only 2 attend the touchstone defined. From these, only 1 shows the real efficience from the use of educational games. The result will contribute for future researches that aim to improve or creat new approaches in this area.
