 Gain Resource ideas
 Have some fun!

Comparing our Students’
and Scientist’ Approach
to Science
Scientists
Perception of Purpose
 Hope to contribute new
knowledge through inquiry
Planning Process
 Debate, argue and challenge
explanations and evidence
 Draw from work of their
peers
 Extensively plan before
beginning
Our Students
Perception of Purpose
 Hope to complete a task
Planning Process
 Struggle to make sense of
what is being asked of them
 Have trouble making a
hypothesis
 Generally prefer to “get on
with it” rather than plan
Comparisons Continued
Scientists
Actions Taken
 Based on what will maximize
their chances of finding
answers
Making Meaning
 Debate even ‘straightforward” evidence
Making Meaning
 Ignore anomalous data and
make changes/adjustments to
the experiment
Our Students
Actions Taken
 Based on what their teacher
tells them to do
Making Meaning
 Assume that the correct
meaning of data will be evident
based on experiment results
Making Meaning
 Associate anomalous data with
mistakes
Instructional Shifts for 2014 Science



A greater need to teach higher order thinking and
problem solving skills
◦ Levels 1, 2, and 3 of Webb’s Depth of Knowledge
will be incorporated into the 2014 test
Integrate the content areas
◦ Data analysis will be measured on the science,
social studies, and math tests
Teach academic vocabulary that crosses content
areas
◦ Mean, median, mode, probability (math, science,
social studies)
Instructional Shifts (cont.)


Use content-rich materials and websites to teach
concepts
◦ Test takers will need a definitional understanding
of the assessment targets
◦ Develop each test takers background knowledge
Integrate digital literacy skills
◦ Dragging and dropping, navigating tabs, radio
buttons, etc
What Is It?
Science Practices
Basic scientific practices assessed on the 2014 test:
•Determining details and making inferences
•Determining central ideas, hypotheses, and conclusions
•Analyzing events and ideas
•Interpreting meaning of symbols and terms
•Analyzing structures
•Integrating content presented in diverse ways
•Evaluation reasoning and evidence
•Analyzing relationships between sources
•Reading and interpreting graphs, charts, and other data
representations
•Measuring the center of statistical dataset (Hand-out)
•Determining sample space and using probability models to interpret
data
•Understanding and applying the appropriate tools,
techniques and units in scientific investigations (Hand-out)

TEACHING STRATEGY: TWENTY-FIVE
Write a summary for the following passage
The process of digestion begins with your first bite of
food. Digestion takes place in your mouth, stomach, and
intestines. During digestion, food is broken down into
small molecules that pass into the bloodstream. The
process of absorption comes next. During absorption,
food molecules, now in the blood, pass into cells. In the
next process, assimilation, cells use the food molecules
as a source of energy and for body growth and
maintenance.

In our solar system, eight planets orbit the sun. The average distance of a
planet’s orbit is measured in astronomical units (AU). One AU is the average
distance between Earth and the sun, which is about 93 million miles, or 150
million kilometers. The table below shows the distance of each planet from
the sun; its period of rotation on its axis; and its period of revolution around
the sun.

TEACHING STRATEGY: WHO’S THE EXPERT
Write an example that demonstrates a learned behavior
Below are five types of behaviors shown by all vertebrates –animals with
backbones.
Inborn behaviors
Reflex – an automatic response to a stimulus
Instinct – a complex, unlearned response that is not dependent on experience
Self-preservation – a reaction for the purpose of escaping life-threatening
danger
Learned behaviors
Conditioned response – Learning that connects an unusual stimulus with a
desired response
Intelligent behavior – a complex response that uses past learning in new
situations
From: Top 50 Science Skills for GED Success (McGraw Hill)
THE QUESTION/ANSWER IN THE BOOK
Each time Andy claps his
hands, his parakeet sings.
What type of behavior
is the parakeet showing?

TEACHING STRATEGY:VALUE LINE
What is the pH of acid rain?
The pH scale, from 0 to 14, measures the acidity or alkalinity of a
substance. Pure water, with a pH of 7, is neutral. Acids have pH
readings below 7; bases have pH readings above 7. The lower the
pH, the more acidic the substance. Normal rainwater ranges from
5 to 6.5. Tomato juice has a pH of 4; lemon juice has a pH of 2
Al hypothesized that acid rain (not normal rain) fell in his city. To
support his hypothesis, which pH range must his rainwater
readings fall into on average?
