This book specifically addresses the challenges we have faced during more than ten years of research into different topics regarding teaching practices, from subjects such as the relationship between the planning of practices and their application in specific classroom contexts to others linked to task management in the direct teaching of content. Next, this compilation is interested in providing some insight for teachers to be able to use classroom artefacts and to convert them into real tools useful in students' learning. A study that aims to raise educators' awareness and inform them about the scope and implementation of instruction management is presented. It focuses on primary education, which is a critical step for learners to be equipped with the necessary skills to join knowledge-based economies. The purpose of the penultimate chapter is to analyse the relevance of knowledge in the search for improvement in teaching practices, taking as starting point the lack of a single path of teacher improvement. A qualitative study presented in the final chapter explores challenges facing the implementation of teaching in an open, distance and e-learning institution, and identifies ways in which these challenges can be mediated. The challenges are related to school placement, supervision, mentoring, administration, resources, assessment and communication.
