This study investigates pedagogical content knowledge (PCK) among teachers teaching mathematics at the preschool level in Colombia, highlighting the importance of integrating mathematical knowledge with innovative and effective pedagogical strategies. Using a mixed exploratory and transactional methodology, the perceptions and practices of 82 teachers were examined, focusing on their understanding of mathematical content, pedagogical skills, and knowledge of children’s cognitive development. The findings reveal a significant gap in teachers’ understanding of these concepts, indicating a critical need to strengthen PCK among teachers. To this end, training should be provided to enable teachers to foster meaningful and contextualized mathematical learning in preschool students. The study suggests reviewing teacher training curricula and fostering the development of pedagogical strategies that prioritize conceptual understanding and mathematical reasoning. Additionally, it identifies critical areas for improvement and offers concrete recommendations for transforming mathematics teaching in preschool education. To enhance the quality of mathematics education, several measures are proposed: ensuring continued availability of training programs for teachers, encouraging collaboration between educators, adopting constructivist approaches, and helping teachers understand the value of mathematics learning outside the school.

The South African government has undertaken to expand universal access to Early Childhood Development (ECD) with a particular focus on children from socially disadvantaged communities and with disabilities. This requires training and support of ECD practitioners, such that they are equipped 399with the necessary knowledge and competencies to implement effective teaching and learning approaches at ECD level. This research explored an innovative, inclusive approach to ECD practitioner development in which both Deaf and hearing students were enrolled in an ECD practitioner training program facilitated jointly by New Beginnings (an ECD non-profit training organization) and the Deaf Federation of South Africa (DeafSA). The research scrutinized key aspects of the training program, including how it extended students content knowledge on ECD, their pedagogical knowledge; as well as epistemological access for Deaf students. The findings and conclusions have important implications not only for equipping ECD practitioners with knowledge and skills, but also demonstrates how practitioner training itself can be effectively structured to cater for diversity among trainees.
