Teaching for Conceptual Understanding in Science | Posted in Professional Development
Currently, I am entering my 4th year of teaching 7th and 8th grade science. I’ve always felt that the traditional lecture format my department employs is not the most effective way to reach my students. I’ve added numerous lab activities in an attempt to promote deeper understanding. However, it wasn’t until I stumbled across this thread and read about conceptual understanding that I felt like this is the method that I should have been using all along. The shift to NGSS blends perfectly with this style of instruction and learning. I agree with Joyce in regards to covering the curriculum. We tend to sacrifice depth of learning in favor of squeezing everything in before the next round of state testing begins.
I have read and reviewed many of the resources provided in your book “Teaching for Conceptual Understanding in Science.” I felt the different instructional strategies listed in chapter 8 were extremely beneficial. I’m left with a few lingering questions though. Based on what I’ve read, teachers need to administer some sort of probe or pre-assessment to gauge students’ misconceptions or prior knowledge before planning instruction. Are these probes supposed to take the entire class period? If not, then how do you plan the day based on information you are gathering in a 15-20 minute time span? Using the conceptual thinking model how are teachers providing instruction for concepts that are completely unfamiliar to students?
Inquiry-Based Learning in Elementary School | Posted in Elementary Science
I believe that inquiry based learning is also extremely beneficial for students especially at the lower elementary grades. Like mentioned by others, this type of learning helps the students think for themselves. There are also different types of inquiry based learning, depending on how much direction you would like to give the students. If you are going to completely hand over the reins to the students this is called an open inquiry. In this inquiry the students will be in charge of coming up with a question/problem, procedure, and results/ analysis. This would be a great way to get the students to think creatively and problem solve. However, for the younger students it could be hard for them to come up with everything on their own. So, for this age group I would recommend a structured inquiry. For this, you as the teacher would come up with the question/problem, and the procedure for everyone to do. Then the students would have to analyze and reason as to why these things occurred. In my science methods class we did an experiment called "dancing raisins for our structured inquiry. We were given the question of, "Why do raisins, when added to a cup of sparkling water float to the top of the cup?" We were also given the procedure of putting five raisins in two cups with the same amount of liquid, one with sparkling water and one with regular water. Then it was our job to analyze why it was that the raisins floated in the sparkling water. I think that this would be a great idea of a structured inquiry for younger elementary grades. You can structure it, but still gets them thinking!
Teaching Science to Kindergarten in a Short Time Frame | Posted in Early Childhood
I think that the best way to teach your students science with only fifteen minutes is using problem based learning approaches. You could do that through quick STEM challenges. From my experience, STEM challenges are a quick and fun way to briefly introduce science topics while engaging students at the same time! Also, you could always incorporate science into other subjects, as well. For example, if you are teaching literacy, have the students read a science article, etc. I hope this helps!
