2004 Survey Results: Teachers Teacher Feedback (511 respondents, +287)
• 50% (+13%) were undergraduate or higher, 30% (+3%) were 9 - 12 grades, 13% (-8%) were 6 - 8 grades, 6% (-9%) were K-5
• 67% (+4%) of respondents teach Earth science or related course(s)• Most of our respondents encourage
students to visit the EO — 35% (-17%) said “Often,” and 41% (+12%) said “Sometimes”; 11% said “Never”
• Most of our respondents incorporate materials from the EO into their class- room lessons
– 29% (-15%) said “Often,” & 43% (+5%) said “Sometimes”; 12% (-2%) said “Never”

Student Feedback (239 respondents, +59)• 87% (+6%) were undergraduate or higher, 8% were grades 9 - 12 (-5%),
and 3% (-2%) were grades 6 - 8• Interestingly, 74% (+6%) said their teachers “Never” encouraged them to
visit the EO — indicating students are finding it on their own• 66% (-3%) of respondents have used the
EO as a reference tool when doing schoolwork assignments, while 34% (+3%) have “Never”
Use the EO for schoolwork assignments?

Merging Technology & Pedagogy
Earth Observatory is a powerful tool for teachers that can enhance learning
Even the best tools can be underutilized Interest in promoting an inquiry approach
• Connect inquiry and technology through real data use in the classroom
• Use technology to explore large, intangible concepts

The 5 E’sBiological Sciences Curriculum Study
(BSCS) Engage – students in the topic
Explore – the topic with others
Explain – the topic, guide to understanding
Elaborate – to help students extend their understanding
Evaluate – student learning & understanding

Modeling the 5E’s First page is a
case study about the Carbon Cycle that engages the teacher
We will model the 5E approach while teaching about the tool

Engage: Carbon Case Study
Between one and two billion metric tons of carbon per year are “missing” from the global carbon budget. In other words, scientists cannot account for 15 to 30 percent of the carbon that humans annually release into the atmosphere…
…we can generate animations that help us visualize the pathways that it follows.

Explore and Explain
Teachers are guided through an example data set comparison (structured inquiry)• Vegetation Index (greenness) versus Rainfall
• Vegetation Index versus Surface Temperature
• Primary Productivity versus Surface Temperature
• Fires versus Rainfall and/or Vegetation Index anomaly
• Fires versus Fine Aerosol Particles
• Still to come: Fires versus Carbon Monoxide
Teachers are then encouraged to examine additional datasets that may be relevant to the case study (problem solving challenge)
The associated instructions provide explanations about the datasets and how to build animations

Elaborate Teachers are pointed to additional stories, datasets and tools for
further investigation (these are mostly terrestrial in focus)• The Mystery of the Missing Carbon -

Conclusions Each tool has many more educational uses than can be
explored in a single EET chapter• Focus on one or a few aspects
Each team member brings individual strengths to the effort• Embrace diversity• Avoid “too many cooks”
Integrate pedagogy and technology• Model the approach in your EET chapter
Next Steps:• Develop an evaluation and assessment strategy• Present lesson to teachers for incorporation into their classrooms• Collect data on lesson’s effectiveness
