Professional development is effective and beneficial to the development and improvement of one's teaching practice, and because education is a dynamic field that evolves over time, teachers must be willing lifelong learners in order to provide the best opportunities for success to all children while incorporating/implementing all strategies, techniques and tips into their teaching practice to meet the needs of all learners. There were various formal professional development courses in which I participated that provided many valuable insights and strategies that are being used in the classroom to improve the teaching/learning process. They all challenged my thinking and helped me to improve my practice for the better, but it was the informal one that stood out and continues to stand out for me the most, working hand in hand with my colleagues; an example of one way in which we collaborated was by assisting in the creation of learning resources/materials based on the term's theme that are tailored to the children's individual needs and then placed in each learning center for daily use. Whether professional development activities are conducted formally or informally, the goal should always be to improve/enhance the children's learning in some way through the knowledge one has gained.
