Innovations in technology: a friendly math project and the learning analytics “challenge”

Currently the world around us "reboots" every minute and “staying at the forefront” seems to be a very arduous task. The continuous and “speeded” progress of society requires, from all the actors, a dynamic and efficient attitude both in terms progress monitoring and moving adaptation. With regard to education, no matter how updated we are in relation to the contents, the didactic strategies and technological resources, we are inevitably compelled to adapt to new paradigms and rethink the traditional teaching methods. It is in this context that the contribution of e-learning platforms arises. Here teachers and students have at their disposal new ways to enhance the teaching and learning process, and these platforms are seen, at the present time, as significant virtual teaching and learning supporting environments. This paper presents a Project and attempts to illustrate the potential that new technologies present as a “backing” tool in different stages of teaching and learning at different levels and areas of knowledge, particularly in Mathematics. We intend to promote a constructive discussion moment, exposing our actual perception - that the use of the Learning Management System Moodle, by Higher Education teachers, as supplementary teaching-learning environment for virtual classroom sessions can contribute for greater efficiency and effectiveness of teaching practice and to improve student achievement. Regarding the Learning analytics experience we will present a few results obtained with some assessment Learning Analytics tools, where we profoundly felt that the assessment of students’ performance in online learning environments is a challenging and demanding task.

The background impact in HEI math lectures: an experience in math in the 1st year of Accounting and Management Degree

It is a fact, and far from being a new one, that students have been entering Higher Education courses with many different backgrounds in terms of secondary school programs they attended. The impact of these basic skills is a general and worldwide challenge, fundamentally when facing some specific “constructive” subjects like foreign languages and Mathematics. Working with students with an extensive variety of Math qualifications is an outrageous challenge when they enter an advanced Math course, leading to an almost generalized expectations’ failure - from students enrolled in course and from their teachers, who feel powerless in trying to monitor knowledge construction from completely different “starting points”. If teachers’ "haste" is average, more than half of the students do not “go along” and give up, even before experiencing any kind of evaluation procedure. On the contrary, if the “speed” is too low, others are discouraged (feeling not progressing at all) and the teacher runs the risk of not meeting the minimum objectives (general and specific) of its course, which may have a negative impact on students’ future training development. Failure in Mathematics, despite being a recurrent and global issue, does not have any “magical solution”, however, in general, teachers in this area seem untiring, searching, investigating, trying and implementing new and old “recipes” to tackle and demystify this subject. In this article we describe a project developed in a Math course, with the first year students from an Accounting and Management bachelor degree, and its outcomes since it was brought to practice, revealing its impact in students’ success, from approval to dropout rates, in this course. We will shortly describe students’ differentiated Math backgrounds, their results in a pre-assessment analysis and how we try to deal with these differences and level them up, having in mind the same “finish line”. One should never forget that all these students where officially accepted in higher education institutions, so they are ones’ reality, the reality of institutions whose name one should value and strive to defend.

A aquisição de competências matemáticas no 1º e 2º ciclos:construção de um instrumento e intervenção com base nos seus resultados

Com base no modelo de Resposta à Intervenção (RtI), este estudo centrouse em três objetivos: construir um instrumento vocacionado para a determinação do nível de competências fundamentais, do 1º ao 6º anos, na disciplina de Matemática; avaliar o valor preditivo do instrumento sobre a necessidade de intervenção; examinar o efeito de uma intervenção planeada com base na avaliação diagnóstica desse instrumento. Para dar resposta ao primeiro e segundo objetivos foram consideradas duas amostras de conveniência: a primeira, constituída por 5 docentes, avaliou a versão teste do instrumento e a segunda, constituída por 6 docentes, avaliou a sua versão final (perfazendo um total de 75 alunos). Recorrendo ao método kmeans, os resultados mostraram que o instrumento é de útil e fácil aplicação, permitindo aos docentes avaliarem e identificarem o grupo de desempenho a que pertence cada aluno, em relação à média dos resultados da respetiva turma. Relativamente ao terceiro objetivo, foi constituída uma amostra de 7 alunos de uma turma do 4º ano. A intervenção decorreu ao longo de 11 semanas, com 2 sessões semanais, cuja duração variou entre 10 a 35 minutos. Para avaliar os efeitos da intervenção, foi realizado um pré e um pós-teste, assim como 2 sessões de avaliação intermédia (checkpoints), tendo-se recorrido ao teste não paramétrico de Friedman e ao teste de Wilcoxon, para avaliar a significância das diferenças entre os tempos e os níveis de suporte, para o aluno resolver a tarefa com sucesso, respetivamente. Os resultados mostraram diferenças estatiscamente significativas, particularmente entre as duas avaliações intermédia consideradas.
