Project-based learning in a geology classroom | Posted in Evaluation and Assessment

Hi Anna --

The February issue of NSTA's Science Scope has the theme of project-based learning. Although this is a middle school journal, I suspect that the activities could be ramped up a bit for high school. There are good articles on co-designing projects with students and managing group work.

Keeping Students Engaged | Posted in Elementary Science

Andrea, I think along with Katherine said about engaging and hands-on activities, students interpret and understand new information well when they can connect what they learn back to something they are familiar with in real life. In other words, creating meaningful activities and asking purposeful questions that help students think about the subject outside of school terms is a great tool when teaching. I also like KWL charts and flow maps that can help the teacher evaluate if the students have gotten the "big picture" out of the lesson.

The Drake Equation | Posted in Earth and Space Science

The Drake equation is not directly used by scientists in their research. Rather it is often used when talking about life in the universe to non-scientists, such as in astrobiology courses, as James mentioned. One of the keynote addresses I sometimes deliver is on astrobiology, and I discuss the Drake equation quite a lot, as it relates to many fascinating topics regarding the development of life in the universe, where we would expect to find life, and how common we might expect life to be.

The purpose of the Drake equation is not to give a precise answer to that fundamental question -- How many technological civilizations are in our galaxy? -- but to form the basis of discussions by presenting various types of information that we would need to know, if we wanted to answer that question.

So basically the Drake equation is a statement that "stimulates intellectual curiosity about the universe around us, for helping us to understand that life as we know it is the end product of a natural, cosmic evolution, and for helping us realize how much we are a part of that universe." (https://www.seti.org/drakeequation)

What the equation and the search for life has done is focus science on some of the issues concerning life in the universe, specifically the development of life starting with chemical processes, the development of multi-cellular life, and the development of intelligence.
