Stimulating Critical Thinking through a Technological Lens

Critical Thinking in Action

Stimulating critical thinking using technology has the potential to create more in depth understanding of science and math content by students when engaged in learning activities which integrate in-class and on-line technology resources.

Technology tools support stimulation of both inquiry-based and critical thinking skills by engaging students in exploring, thinking, reading, writing, researching, inventing, problem-solving, and experiencing the world outside their classroom. This is accomplished through learning content through the lens of video to multimedia to the internet (Using Technology to Improve Student Achievement, NCREL, 2005).

The following are technological integration strategies for stimulating critical thinking and inquiry-based learning in science and math class.

Data Analysis

Analysis of data is an essential skill science and math students must have for success in these two content areas. Examples of technology integration tools and techniques to support this skill include:

Online Data Bases – using real-time data has the ability to allow students to become comfortable with sets of numerical data and use it in meaningful ways. This is particularly crucial when students analyze large sets of numerical data to support developing the ability to draw well reasoned conclusions.

Spreadsheets – besides saving time and organization, spreadsheets stimulate critical thinking as students visualize a change in numbers and ask “what if…” This tool is useful in problem solving, science investigations, general math, algebra, and calculus. An excellent resource for strategies and techniques for integrating spreadsheets in lessons is Spreadsheet Magic by ISTE.

Project Based Learning – student learning benefits both academically and personally from their involvement in project based learning. Student participation in actual real-world learning activities encourages them to do their best work and see the relevance of science and math in their daily lives. Examples include:

Communication of Findings and Conclusions

Communication of findings and conclusions is fundamental to understanding science and math concepts. Without communication, there is no value to a learning activity for any student, teacher, or others. Examples include:

Digital Storytelling – linking project based learning with digital storytelling is natural. The integration of digital technology motivates students, allows them to easily share their work, and encourages collaborative learning. This in turn helps them develop a more in depth understanding of science and math concepts through a digital lens.

Google Docs – offer a set of collaboration and communication tools to help students acquire the skills necessary to help them soar in their education and outside the classroom.

Podcasts – students benefit from podcasting because it reinforces science and math concepts, along with their reading and writing skills as they prepare scripts.

VoiceThread – creates an interactive classroom which can be used in almost any science and math grade level. Teachers can use this Web 2.0 tool for digital storytelling of concepts by students, causing critical thinking, student project presentations, and even a tool for assessment.

Both on-line and in-class technology tools promote authentic communication and collaboration between teaches to students, students to students, and students to teachers. Also, these tools provide authentic inquiry-based learning, project-based learning, and problem solving situations which stimulate critical thinking in science and math.


Using Google Earth in Science and Math

Google Earth

Google Earth

Google Earth is free and lets you fly anywhere on Earth to view satellite imagery, maps, terrain, 3D buildings, from galaxies in outer space to the canyons of the ocean.

You can explore rich geographical content, save your toured places, and share with others.

New additions to Google Earth include the ability to explore under the oceans and take a 3D trip to Mars.

Educational Uses of Google Earth

The following are examples of the way Google Earth can be used in science and math:

Rising Sea Level Animation

This file animates one scary potential effect of climate change — rising sea levels. Will your house be underwater? Will the desert become an ocean? Use the time slider to see which locations will be submerged as the planet’s oceans rise. Note: it’s important to turn on the terrain in the “Layers” section of the Google Earth client. And for added effect, turn on the 3D buildings layer.

Real-time Earthquakes

Want to explore the world’s seismic hot spots in real-time? From the Pacific Ring of Fire to the San Andreas Fault, this KML will give you a better geographical understanding of the daily changes occurring on our planet. Each place mark contains data about a specific area’s seismic activity and a link to more extensive information.

Climate Change In Our World Antarctica

Explore and learn about the impacts of climate change and find out how you can make a difference with Climate Change in our World. The Met Office Hadley Centre, British Antarctic Survey and UK Government have harnessed Google Earth technology to present you with an interactive animation showing the retreat of Antarctic ice shelves over time. On opening up the KML you can find out more about how we produced these files, and what is happening on a global and domestic scale to prevent and combat the effects of climate change.

Coral Reef Monitoring

It is estimated that coral reefs cover around 284,000 square kilometers providing a habitat for thousands of species to live. Global warming poses a major threat to these massive living structures and in this file you can explore the state of coral reefs around the world, seeing their distribution and concerns facing their future existence.
