Abstract
• In order to build physical science content knowledge and confidence in teaching K-5, a number of strategies including:• hands-on, • robotic, • concept mapping, and • web-based research activities will be discussed.
• Results from introducing these strategies in Higher Education and Elementary Education classrooms will be presented.
Rationale for the Project

Noticed needs of ECE students, trends Lack of science in grades 1 & 2, coding, Next Generation Science Standards, Brookings School DistrictAstronomy classInternal grant – Academic and Scholarly Excellence to purchase manipulatives
Timeline
• Grant funded—collaboration between BSD and SDSU• Purchased– Simple Machines
and WeDo Robotics• Sue—trial in second grade
and kindergarten• ECE 412 –survey, pretest,
Simple Machines, wrote science lesson plans, post-test and follow up survey
Dispositions Towards Teaching Science• Surveys pre- and post-

Content Knowledge Findings• Pre-test of physics-related concepts, 25 questions: Scores
ranged from 36-76% correct• Post-test of physics-related concepts: • 29 of the 33 students improved their scores • 16 students improved by 1-3 points• 10 students improved by 4-6 points • 3 students improved by more than 6 points
• 2 students’ scores remained the same• 2 students actually had more mistakes on the post-test• Only 1-2 points lower
Caution--Keep your eye on the objectives• So many got the question wrong:
In a perfectly efficient machine, the work input is _____ work output.a. equal tob. greater thanc. less thand. independent of
• Focused on the details that the students lost sight of purpose
Building Confidence as well as Content Knowledge• Manipulatives—LEGOs, common items (ex. bucket with washers,
SMILES, etc.)• Problem-solving (theme within NGSS: process AND product) • Making predictions (ex. dropping items at same time)• Books (trade books)• Concept Maps (pre and post?) VUE K-W-L Bubbl.us Tree of LIfe• Web-based research activities • creation of informational text to help build content knowledge
• Harvest
Benefit--Integrated Curriculum
• Tie math and language arts standards• 21st Century skills• Working with technology teacher • We (classroom teachers) focus so much
on isolated skills, but children are motivated to learn through “play”
Coding with Kids
• Programming: Scratch, LEGO Robotics, LabVIEW
Discoveries
• Large percentage felt unprepared to teach science pre and post• Primary grade science• Focus on reading and math (Common Core)• Children naturally fascinated by science activities (curiosity, inquiry, willing to
take risks)• Time for scheduled science instruction tends to start in 3rd grade• Are teachers in these grades science-phobic?• Attitudes toward teaching science improved, but knowledge of understanding
principles did not…assumed they would know that, but they didn’t…got caught up in the process and use of manips rather than focusing on learning objectives (universal concern)
Future studies
• Learning with manipulatives• Learning style inventory• Survey that is independent of course/instructor…would the results be
the same? (3rd party evaluator)• Validate questions• Science adverse teachers in primary grades?• Depth of understanding when teaching science…positive attitudes,
but what are they teaching?• Your interest in using WeDo or Simple Machines?
