TPACK stands for technological pedagogical content knowledge, and is what all teachers are supposed to work towards in the classroom. When broken down, content knowledge means knowing the necessary information in a particular subject, pedagogical knowledge means knowing how to teach this information to students, and technological knowledge means knowing how to effectively incorporate technology into a lesson plan. It is important for every teacher to understand the concepts of TPACK, because our world is becoming more and more technologically advanced. Students are used to having technology in their daily lives and the constant stimulation they provide. For this reason, it would be unwise for a teacher to completely ignore technology or leave it out of the classroom. Technology is becoming an imperative aspect of classroom learning. However, technology must be used wisely and purposefully. It should only be incorporated into a lesson plan if it will enhance the students’ learning. This leads to an important aspect of TPACK: it is not only about technology. First and foremost, a teacher should know the subject they are teaching and how to teach it. Technology does not replace pedagogical or content knowledge, but rather adds another dimension to it. Arguably, the most effective teachers will be the ones that understand and use the concepts of TPACK in the classroom. I, as a future teacher, have a responsibility to my students and my school to be that effective teacher, who knows how to provide students with an excellent education in the 21st century.
