In summary of the lecture slides, there will always a conflict between the traditional usage of pens/pencils and technology. It is the question of where we want to be ourselves, with much of a technology advancement world I personally prefer to challenge myself to move forward but not forgetting the basics of pen and paper as well. For an adventurous person, challenges are always great to measure the achievement of every milestone in various skills rather than just staying stagnant. Although internet could be quite misleading and contradicting at times, we have to explore and determine its reliability of sources. When the perception has change, I can actually go greater heights to improve my teaching in school in the near future.
