CTS and Inquiry Chapter 4 pp 77-79 What contributed the most to your knowledge of how students learn The abilities of inquiry?
The CTS Funnel Controlling Variables Experimental Design Inquiry Skills and Dispositions
What is the Difference between a Scientific investigation and an experiment?
CTS Section II- Discussion Question for “Experimental Design” Using the summary sheet for Section II- What instructional considerations described in the standards (K-12 or at specific grade levels) should we be aware of if we want to develop the skill of designing experiments?
Section III Discussion Question- Learning Goals Using the summary sheet for Section III- According to the standards, what are students are expected to know and be able to do at different grade levels related to the topic of “Experimental Design”? Summarize one or two specific skills.
At what grade span are your students expected to know how to identify and control variables?
CTS Section IV- Discussion Questions for “Experimental Design” Using the summary sheet for Section IV- 1)How does the research on student learning related to experimentation and variables help you consider how and when students learn the skills of “Experimental Design”? 2)What developmental issues should be considered?
Applying CTS Results to An Instructional Scaffold
Scenario Ken noticed his rubber ball did not always bounce the same way when he dropped it. He wondered how different surfaces affected the way his ball bounced.
PRE-EXPERIMENTAL DESIGN CONSIDERATIONS Phenomenon, object, or event being observed: What am I wondering about (initial question)? : What prior knowledge, including observations made, do I have about this?
Part A: Things I could change or vary about the phenomenon, object, or event
Part B: Things I could measure or observe about the phenomenon, object, or event:
IDENTIFYING VARIABLES I will change: I will measure: The type of surface The height of the bounce
I will not change (conditions held constant so it is a fair test): Place remaining sticky notes from Part A here. The type of ball The height the Ball is dropped from The temperature of the ball
I will not measure: Place remaining sticky notes from Part B here. TimeDirection Number of bounces
FORMULATING A QUESTION (Refining the initial question) When I change: What will happen to: The surface The height of the bounce
Based upon my question, I predict (or hypothesize):
The Experimental Design Materials I will need: What I will change or vary (also called the independent variable) The surface
What I will do (how I will carry out the change): Number of trials I will conduct: The data I will measure or observe (the dependent variable). The height of the bounce
How I will collect the data: How I will record and display the data (for example- table, graph, chart, picture)
Think and Share How does the student scaffold support the findings from the CTS on Experimental Design (learning goals, instructional considerations, and research on student ideas) ?

How Likely Are You to Use the Scaffold and CTS? CTS by itself is not enough. CTS, combined with classroom applications, helps all educators develop a common language and understanding about teaching and learning that can be used to inform classroom practice in a way that is meaningfully aligned with standards and research on student learning.
“By taking the time to study a topic before planning a unit or lesson, teachers build a deeper understanding of the content, connections, and effective ways to help students achieve understanding of the most important ideas and skills in that topic.” CTS p 7
