Thinking like a scientist means coming up with hypotheses, even ones that might seem plausible but are ultimately incorrect. In her biology course, Paola Arlotta responds to student comments, including the incorrect ones, with positive feedback. In this video, Arlotta explains that by doing so she aims to create an environment in which students feel comfortable thinking creatively and speaking up even when they are stretched to the limits of what they know for certain.
One of the lecturer’s biggest fears remains ending class without having addressed enough of the material he/she planned to cover. To prevent this, Paola Arlotta identifies four or five key topics to address in a particular lecture before class. If discussion runs long on one of those topics, she makes quick decisions about how to reshuffle timing to ensure her objectives are met by the end of the lesson.
While slides can be helpful for displaying class material, they also tend to be static and relatively passive. Conversely, co-constructing knowledge on the board with students can help make definitions and key concepts come alive. In this video, Paola Arlotta describes how recording students’ ideas on the board engages them in collaboratively “building the class material” and involves them more deeply in the learning process.
Instead of using lectures to simply deliver information, instructors can also use them to create opportunities for students to construct new knowledge themselves. In this video, Paola Arlotta explains how she presents material to students so they first construct their own understanding of concepts, then builds on their ideas to develop more formal disciplinary knowledge and vocabulary.
Some instructors design lectures that simply telegraph answers to students. While there are certainly cases where it makes sense to deliver answers this way, a wholesale dependence on this approach will likely mute students’ drive to discover answers for themselves, resulting in a class of students who depend on you rather than on themselves to solve problems. Infusing lectures with questions that spark students toward self-discovery, however, can help to foster more productive, interactive learning spaces. Paola Arlotta uses leading and “prodding” questions to help students...
Challenging students to step into the shoes of experts within their fields and consider problems from specialized points of view can make material more relevant and help students develop crucial disciplinary instincts. The ultimate goal of the history instructor, for instance, is for his/her students to be not only well-versed in the content but also able to think like historians. In every one of Paola Arlotta’s class sessions, she presents multiple experiments for students to design or interpret so they can gain confidence and practice thinking like scientists. In this video, she...
Tapping into the energy in the classroom to make real-time decisions for keeping students engaged, curious, and challenged may prove more effective than blindly following a scripted lesson plan. In this video, Paola Arlotta describes how she uses advance planning and in-the-moment data from students to know when is appropriate to increase the level of difficulty or reveal surprises in the content.
