Three goals for this session 1.Instruction should focus on children learning observable patterns and then explaining those patterns through the use of the actual motions of celestial objects. 2.Teachers need to be aware of and respond to children’s prior knowledge and alternative ideas about celestial motion. 3.Learning celestial motion requires that ALL children are involved kinesthetically and with their own personal use of models.

Kinesthetic learning The focus of the lessons that we are giving you here is kinesthetic. Everything we do is kinesthetic. When you show students the path of the sun you can use the students’ own kinesthetic motion to fully engage their minds in the experience. Third grade teacher: “Don’t be afraid to try and the kinesthetic approach really works!” NSTA 2010Julia Plummer (Arcadia University) Using Children’s Observations Cynthia Slagle (Colonial School District)

Prior Knowledge What do you think? What do your students think? Do the stars appear to move at night? Why or why not? Here is the sun (poster). How big would the sun be on that scale? – How far away would you put the earth from the model sun? – Where would the stars be?

Learning Progression Levels Naïve: Believes that what we observe happening in the sky is what is actually happening – e.g. Sun rises/sets because it is actually moving up and down Synthetic  next slide Scientific  next slide Plummer & Slagle, 2009; Vosniadou & Brewer, 1994 NSTA 2010Julia Plummer (Arcadia University) Using Children’s Observations Cynthia Slagle (Colonial School District)

Learning Progression Levels Naïve Synthetic: Combines aspects of the naïve view with aspects of scientific explanations. – Lower level synthetic: Sun rises/sets because sun goes up and down but earth also spins to face us towards and away from Sun. – Upper level synthetic: Sun rises/sets because of earth’s rotation but moon rises/sets because moon goes around earth every day. Scientific  next slide NSTA 2010Julia Plummer (Arcadia University) Using Children’s Observations Cynthia Slagle (Colonial School District)

Learning Progression Levels Naïve Synthetic Scientific: Applies earth’s rotation to explain the apparent rising/setting of sun, moon and stars on a daily basis – More advanced: Knows that Moon orbits once every ~28 days* but that this does not cause moon to appear to rise/set NSTA 2010Julia Plummer (Arcadia University) Using Children’s Observations Cynthia Slagle (Colonial School District)

Kinesthetic vs Traditional instruction Kinesthetic (explaining observations) Began mostly synthetic explanations Moved to 50% SCIENTIFIC explanations Moved to mostly scientific descriptions of OBSERVATIONS Traditional (Definitions and sun- centered model) Began half naïve/ half synthetic explanations Moved to mostly synthetic explanations Descriptions of observations REGRESSED (less scientific) NSTA 2010Julia Plummer (Arcadia University) Using Children’s Observations Cynthia Slagle (Colonial School District)

Implemented kinesthetic curriculum in 3 rd grade classrooms Analysis not complete but results look favorable (greater improvement than traditional) – Belief that their students are learning more now than before. Teachers report high levels of enjoyment in teaching the new strategies Teachers now have a better understanding of content and strategies I think the kinesthetic stuff really helped. You can only show so many videos. I think that getting them up and moving and having the appropriate materials really is key…. Getting them to use their body… and actually be earth while we had the sun in the middle of the room really helped…(Teacher A, 3 rd grade) NSTA 2010Julia Plummer (Arcadia University) Using Children’s Observations Cynthia Slagle (Colonial School District)

I do think to be honest the initial lessons of the earth’s rotation and revolution are so critical because I think everything else really builds upon that. So as much as, that is one of the most basic concepts, I think that is really, really important. And then … as far as teaching strategies go I think [there is a] need for materials and really getting the kids out of the textbook and do it themselves see it be done, and really try it for themselves, make observations and ask questions. (Teacher B, 3 rd grade) NSTA 2010Julia Plummer (Arcadia University) Using Children’s Observations Cynthia Slagle (Colonial School District)

Honestly the I think all of the resources and the modeling, and letting the kids actually hold the models and do it themselves was most helpful. Because in the beginning I think that a lot of teachers just tend to just show them and think that they understand it but then actually putting it in their hands and saying “well, now explain it to a partner and your partner can explain it to you; or explain it to me” so I can hear their thinking, was most helpful for so many of these lesson to just actually make it hands on for them so they can understand it so much better than if I’m just showing them.

Return to the Main Themes To conclude, our research suggests the following three main points about learning astronomy in elementary school: 1.Instruction should focus on children learning observable patterns and then explaining those patterns through the use of the actual motions of celestial objects. 2.Teachers need to be aware of and respond to children’s prior knowledge and alternative ideas about celestial motion. 3.Learning celestial motion requires that ALL children are involved kinesthetically and with their own personal use of models.
