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 ‘straight forward” 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)

MODIFYING CURRENT MATERIALS AND TEACHING STRATEGIES
Some Strategies for Teaching Science
Virtual Field Trips ◦ http://hubblesite.org
Case Studies Role Playing Mysteries Posters Webquests ◦ http://webquest.org
Concept maps POE Method (Predict, Observe, Explain) Five Es Method (Engage, Explore, Explain, Elaborate, Evaluate)
Strategies Continued Multimedia Presentations Creating Board Games Collaborative Work Problem Based Learning The teacher ◦ ◦ Presents a problem or issue The Students: Explore the issue ◦ List what they know ◦ ◦ Develop a problem statement List the possible outcomes/what they need to know ◦ Research and experiment ◦ Present and defend their conclusions
Strategies for Teaching Science Vocabulary
Reading Science Text Cards ◦ True/false cards ◦ Agree/Disagree Cards ◦ Matching pairs ◦ Sequencing ◦ Classification Word Lists/Word Banks/Word Wall ◦ Procedure Words (compare, contrast, …) ◦ ◦ Opposites Movement Words (accelerate, float, …) Word Games (Hangman, Pictionary, …) Word Parts [metamorphosis – meta (large), morph (change), osis (process)] Graphic Organizers Multiple Meaning Words (matter, conductor, …)

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.
From: Top 50 Science Skills for GED Success (McGraw Hill) Skill 1: Summarizing the Main Idea
The answer the book gives: Food nourishment takes place in three equally important steps
Recreate Charts with Other Visuals 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 Instinct
– an automatic response to a stimulus – a complex, unlearned response that is not dependent on experience
Self-preservation
danger – a reaction for the purpose of escaping life-threatening
Learned behaviors
Conditioned response
desired response – Learning that connects an unusual stimulus with a
Intelligent behavior
situations – a complex response that uses past learning in new From: Top 50 Science Skills for GED Success (McGraw Hill)

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?
