- Data analysis and learning analytics for measure effects of gamification in a math online projectPublication . Lopes, Ana Paula; babo, lurdes; Azevedo, Jose Manuel; Torres, CristinaNowadays the use of the information and communication technologies (ICT) is more and more common in the learning and teaching process. Modern forms of education have risen and these require the implementation of new learning paradigms: situated cognition, student-centred learning, distributed cognition, constructivism, and communities of practice, among others. However there is an important problem that concerns educators, the lack of student motivation and engagement in education, especially in the e-learning environment (Online Education, Online Courses), where the motivation and the active role of students are definitely the key. Therefore, the interest of researchers in the subject of gamification, which main pillars are motivation, progressiveness and instant feedback, has increased. Furthermore, influence of gamification, depending on utilized components (challenge, curiosity, competion, recognition, etc) may have different effects on students. Thus, there is a need of deeper understanding of dependencies between engagement and implemented gamification elements. The goal of such analysis could be personalization of an e-learning system based on a model that enables management of gamification process individually for every student. The purpose of this paper is to investigate how gamification affects a Mathematics Online Course that is using this model as a pedagogical strategy. It relates such strategy with active learning practices and discusses its effectiveness, investigating how gamification can motivate students to participate more deeply and even to change their self-concept as learners. Moreover, the learning analytics and data analysis shows that implementation of the gamification components contributes to the engagement of students in an e-learning environment, having a positive impact on the final grade.
- Teaching and learning mathematics using moodlePublication . Lopes, Ana Paula; babo, lurdes; Azevedo, Jose ManuelThis paper summarizes a project that is contributing to a change in the way of teaching and learning Mathematics. Mathematics is a subject of the Accounting and Administration course. In this subject we teach: Functions and Algebra. The aim is that the student understand the basic concepts and is able to apply them in other issues, when possible, establishing a bridge between the issues that they have studied and their application in Accounting. As from this year, the Accounting course falls under in Bologna Process. The teacher and the student roles have changed. The time for theoretical and practical classes has been reduced, so it was necessary to modify the way of teaching and learning. In the theoretical classes we use systems of multimedia projection to present the concepts, and in the practical classes we solve exercises. We also use the Excel and the mathematical open source software wxMaxima. To supplement our theoretical and practical classes we have developed a project called MatActiva based on the Moodle platform offered by PAOL - Projecto de Apoio Online (Online Support Project). With the creation of this new project we wanted to take advantage already obtained results with the previous experiences, giving to the students opportunities to complement their study in Mathematics. One of the great objectives is to motivate students, encourage them to overcome theirs difficulties through an auto-study giving them more confidence. In the MatActiva project the students have a big collection of information about the way of the subject works, which includes the objectives, the program, recommended bibliography, evaluation method and summaries. It works as material support for the practical and theoretical classes, the slides of the theoretical classes are available, the sheets with exercises for the students to do in the classroom and complementary exercises, as well as the exams of previous years. Students can also do diagnostic tests and evaluation tests online. Our approach is a reflexive one, based on the professional experience of the teachers that explore and incorporate new tools of Moodle with their students and coordinate the project MatActiva.
- Using a spreadsheet to support e-assessmentPublication . Azevedo, Jose Manuel; Pedrosa, AntónioSome of the courses of the scientific area of Mathematics at ISCAP use multiple choice questions (MCQ) tests as a fundamental part of the assessment. The assessed topics include Differential and Integral Calculus, Algebra, Statistics, and Financial Mathematics. In the undergraduate programs of Accounting, Marketing and International Commerce, these courses are taught in theoretical-practical classes and their main objective is to provide the necessary support tools to other courses of these programs. On the other hand, these undergraduate programs, in particular Accounting, have many classes and many students, so MCQ tests have been an indispensable tool for both continuous and final exam assessment. The open source MOODLE platform, used through a local network intended only for continuous assessment, has been the support software for MCQ tests. In order to integrate student classifications so as to be more easily retrieved by all teachers, and in order to obtain them more quickly, an MS ExcelTM spreadsheet was developed. This allows us to automate the whole process from collecting the students’ answers, to obtaining their final classification and calculating important statistics. This paper describes the development process of this tool, which has proved extremely important in the e-assessment method already implemented. Therefore, some of the results presented show: (i) the substantial reduction in the time elapsed between the moment the tests were carried out by the students and the moment of the publication of the grades; (ii) the existence of automatic control in case of duplication of tests by the same student, (iii) the action of complementing MOODLE in the treatment of negative grades of students; (iv) the possibility of performing several statistical analysis that can be organized by class, by subject, by attendance regime to classes (nocturnal versus diurnal), and include comparisons with previous years and tables of frequencies of grades.
- Using data mining with time series data in short-term stocks predictionPublication . Azevedo, Jose Manuel; Almeida, Rui; Almeida, PedroData Mining (DM) methods are being increasingly used in prediction with time series data, in addition to traditional statistical approaches. This paper presents a literature review of the use of DM with time series data, focusing on short- time stocks prediction. This is an area that has been attracting a great deal of attention from researchers in the field. The main contribution of this paper is to provide an outline of the use of DM with time series data, using mainly examples related with short-term stocks prediction. This is important to a better understanding of the field. Some of the main trends and open issues will also be introduced.
