Next Generation Science
Standards
Implementation in Liberal Studies at
CSU Bakersfield
The Project
• Increase abilities of pre-service K-8 teachers in
knowledge and practice of NGSS
• 2 main components
– SCI 325A: Integrated Science from a life science
perspective
• Capstone science course in Liberal studies
– EDTE 310: Early field experience in teaching
• Goal: Integrate and align content and practice
Content: SCI 325A Integrated Science
• Adjusted course content to more closely align
with NGSS
– Including small-scale introduction of Engineering
principles
• Added module on Academic Literacy
• Revised lesson plan assignment
– Replaced CA Science standards with NGSS practices,
crosscutting concepts & performance expectations
– Peer review with revision
– Academic language component
EDTE 310: Early field experience
• Change venue and verb
– From in-school school observation to After school
teaching
– Lesson-plan assignment aligned to SCI 325A
• Ideally, extension of 325A lesson plan
• Practice: students teach the lesson they designed
– With opportunity for revision
Assessment
• Teaching skills and Abilities
– 25 item pre-post Science Teacher Efficacy Belief
Instrument (Reference)
• Asks specifically about teaching practices
• Content knowledge
– 46 item Pre-post course Knowledge survey (Reference)
based on NGSS and SCI 325A content coverage
• 12 practice only items; 17 content only, 17 practice & content
• Composite measure: Average change (post-pre)
• All results on SCI 325A students
– EDTE 310 students excluded because n<5
STEBI
• Each question analyzed individually for Students
taking SCI 325A (Wilcoxon sign-rank test)
• Two items showed significant changes:
– “When teaching Science I usually welcome student
questions” showed a significant change towards the
“Disagree” end of the scale (p=0.046)
– “I know the step necessary to teach Science concepts
effectively” showed a significant change toward the
“Agree” scale (p=0.031)
• 23 remaining questions showed no change

More NGSS
• Multiple regression analyses:
– Independent analysis for each question subset
– Prior GPA, Exam performance, and Lab
performance as Independent variables
• 1 Significant effect
– Lab performance on practice-only question
subset. (b=0.02, p=0.042)
