To better ensure that the training program will be relevant and useful for high school teachers, the learning needs of the prospective participants were assessed first. Last March this year, Science teachers from a nearby high school answered a "needs assessment survey". Participants were asked to indicate which of the Biology topics in the K-12 curriculum, do they find difficult to understand and to teach. Once they have identified the topics they find difficulty to understand and to teach, they were asked to rank the topics based on urgency - that is, which of the topics do they want to learn first, or are required of them to learn soon.
