In order to be an efficient scientist, individuals need to
demonstrate their ideas. Most often this is done through models. Models show
and explain how a certain scientific thinking or theory is based, and provides
evidence of what we know and how it may look. Unfortunately in the classroom
modeling has often been a fragmented and static tool that shows a small or
limited representations of the real world application.
Through this reading I understood how to incorporate student
thinking and past knowledge in the classroom. In order for my students to
understand science they must have the opportunity to “practice” being
scientist. This is be possible by using effective models in the classroom
that would require my students to build ideas, test, and revise their work and
thinking. This also allows my students to build knowledge and use the activities as
an opportunity to work and make corrective measures like a scientist. When planning a unit, I can can use students’
prior knowledge into the new curriculum and allow students to create a
connection on what they know and what they will learn. This can be used as
anchoring event, where students attempt to explain a science phenomenon with
their own reasoning. By having students come up with explanations, students will
be more engaged and curious to know the “why” or the underlying explanation.
Essential questions can also be used to help guide and relate student lives,
experiences, and allow relevance into the unit.
Next, students can create a model and explanation and throughout the
unit come back and revise their models based off critique of other models, new
evidence, and ideas. These steps of revision can teach students how the science
world is data based, and that accepted principles could be changed and revised
just like their experiment/activities in class.
These readings helped tie together how working as scientists
can allow students to bridge gaps between different principles and allow
students to “create” the work rather just “do” the work. It allows students to
personalize their learning and make revisions, build, and test their ideas
based off new evidence, just like what scientists do in the real world. By
fostering this instruction in the classroom, it ties in student engagement
because students can create models to explain phenomenon that will make sense
to them, while also allowing them to tie concepts into their world.
While reading, I was thinking how my classroom culture and
relationship is an important component in order to effectively use the above
methods. I worry that some students may feel frustrated or intimidated by
revising their thinking, and a foundation of trust needs to be built between student/teacher,
and peer to peer. This way a student is comfortable to put down their guard and
revise, accept new models, evidence, and ideas that may challenge their model.
I love that you are planning to use your students prior knowledge. Sometimes they know more than you would have guessed and can use it to lead you to where you are going with the topic.
ReplyDeleteHaving students come up with their own explanations is great when you look at what we are supposed to be doing with the new standards. That making “sense to them” you mention seems to be a goal to forever be striving to. I will note that I love it when you have one student who “get it” explain it to another even using the same words and then it “makes sense” all of a sudden.
With your worry for revisiting topics I think different experiences could help your students grow. An idea could be that your next unit or even a lab you could have your students come up with a starting concept or hypothesis. Establish that you expect it to be wrong, but you want to see their best guess at this time based off of what they currently know, not what they will be expected to know at the end of the unit. The beginning hypothesis/model or whatever could be something you just check off but no one else ever sees, except for them towards the end of the lab/lesson or unit and they can either revise it or totally redo it. I am thinking something along those lines could help students see that it is expected that not everything is going to be perfect, especially when they do not even know the content yet.
