Retired Lawrence professor David Cook recently became president of the American Association of Physics Teachers. He said he is delighted with the new role because of the influence he will have on young teachers and students of physics. As president, he will have a say in allocating the organization’s financial resources and heading the international physics teacher conference. The AAPT has been around since the early 1930s. The group serves as an organizing body for physics teachers in all levels from elementary school all the way through college. While the organization is international, the majority of its members are in the United States, and Cook said he sees it as a vital institution for reinvigorating the United States’ dwindling interest in physics. The AAPT holds two general conferences every year, which are attended by about 1,000 out of the organization’s 10,000 members. In his new position, Cook will be responsible for running the conferences, overseeing the various committees and facilitating the executive board meetings that occur four times per year. Cook’s presidency is actually a part of a four-year leadership track within the AATP. Candidates start as vice president, become president elect, president, and then serve an additional year as a senior member to support the new president. Cook’s 40-year AAPT membership has given him a lot of time to think about the changes he wants to make while serving as president. Cook likes the direction in which the organization is headed, and he said he wants to support some of the programs started by his predecessors and to begin a few of his own. For example, Cook said he wants to provide additional training to exceptional teachers with the expectation that they will be able to lead other teachers. He also said he thinks it is important to expose children to physics starting at a young age, and he wants to focus on getting middle and high school students excited about physics. To have enough time to become president and help other teachers, Cook retired from his own teaching position at Lawrence, but he said that he will miss teaching. Yet, Cook said his decision to retire was ultimately a positive one, because he believes it gave him the time he needed to do a good job in his leadership roles at the AAPT and to spend more time with his grandchildren. Although retired and president of the AATP, Cook still finds time to talk with students about physics and keeps his office door wide open.
