O momento da inseminação é crucial para a fertilidade em vacas de leite
Santos, Vanda; Carvalho, Paulo; Fricke, PaulInvestigação recente indica que o momento da inseminação artificial (IA), em vacas leiteiras identificadas em cio por sistemas automatizados de monitorização da atividade ou submetidas a programas de sincronização da ovulação e IA em tempo fixo, é crucial para a fertilidade das vacas em lactação, mas que a janela ideal para a inseminação é mais ampla do que se pensava anteriormente.
Joga-Mate: Integrating Games into Mathematics Education
Santos, VandaIt is with great pleasure that we present this special issue of Indagatio Didactica, dedicated to the Joga-Mate International Conference, held at the University of Aveiro on February 21 and 22, 2025. This event brought together teachers, researchers, and educators to explore the integration of game-based strategies and methodologies in mathematics teaching. The nine articles selected for this special issue, wri...

Timing of A.I. is critical for fertility in lactating dairy cows
Fricke, Paul; Santos, Vanda; Carvalho, PauloONE of the most common questions we get about breeding dairy cows involves the importance of insemination timing for cows identified with increased activity using an automated activity monitoring system or submitted to timed A.I. after a synchronization protocol. Farms have widely adopted these technologies, and achieve optimal fertility to A.I., both require that the timing of A.I. occurs within a given time w...
A Rule Based Theorem Prover: an Introduction to Proofs in Secondary Schools
Teles, Joana; Santos, Vanda; Quaresma, PedroIn Proceedings ThEdu'22, arXiv:2303.05360; The introduction of automated deduction systems in secondary schools face several bottlenecks. Beyond the problems related with the curricula and the teachers, the dissonance between the outcomes of the geometry automated theorem provers and the normal practice of conjecturing and proving in schools is a major barrier to a wider use of such tools in an educational envi...
Construction and Validation of the Positive Mental Health Literacy Assessment S...
Chaves, Cláudia; Duarte, João; Sampaio, Francisco; Coelho, Joana; Gonçalves, Amadeu; Santos, Vanda; Sequeira, CarlosLow mental health literacy levels have a profound negative effect on healthcare outcomes, usage of healthcare services and healthcare expenditure. To date, there is little research and a lack of instruments available to address and assess positive mental health literacy levels in community-dwelling adults. Thus, this study sought to develop an instrument to assess positive mental health literacy in adults and t...

Comprehensive learning in mathematics: the contribution of the poly-universe tool
Sousa, Luís; Santos, Vanda; Tavares, DinaLearning with understanding is essential to enabling students to solve problems that they will inevitably face in the future. Students will be more successful, if they are engaged in thought-provoking activities that encourage them to grow in their mathematical understanding and identity. With this study we intended to understand how the application of exploratory tasks for teaching and learning mathematics in ...
Heads-on, hands-on, hearts-on: educators perceptions on vidukids contributions ...
Vaz-Rebelo, Maria Piedade; Bidarra, Graça; Costa, Conceiçao; Evangelista, Simone de Almeida; Santos, Vanda; Thiel, OliverThe integral development of the child is nowadays one of the goals of the education, which implies the use of activities and strategies that involve the various dimensions of the human being in a compre- hensive way. This paper aims to describe and analyse the potential of the pedagogical model of the Erasmus+ Vidukids project to develop ‘Heads-on’, ‘Hearts-on’, ‘Hands-on’ activities. The project aims to explor...
Four Geometry Problems to Introduce Automated Deduction in Secondary Schools
Quaresma, Pedro; Santos, VandaIn Proceedings ThEdu'21, arXiv:2202.02144; The introduction of automated deduction systems in secondary schools face several bottlenecks, the absence of the subject of rigorous mathematical demonstrations in the curricula, the lack of knowledge by the teachers about the subject and the difficulty of tackling the task by automatic means. Despite those difficulties we claim that the subject of automated deduction...
