Advantages of Active Learning in Science and Math Classrooms

Posted by David Wetzel

Active Learning

Active Learning

Active learning has a powerful impact on student learning. How? Student achievement increases through mastery of science and math content as a result of this technique. Students also develop improved problem solving, communication, and higher order thinking skills.

Before discussing the benefits of active learning, I need to establish a definition for this teaching technique.

“Students participate in teaching and learning beyond simply listening to lectures or witnessing demonstrations concerning science or math concepts.”

Four Principles: Basics of Active Learning

Four basic principles guide this teaching technique and stipulate that:

  • learning is by nature an active process
  • students learn in different ways
  • students learning by doing
  • use of higher order thinking skills by analyzing, synthesizing, and evaluating (Bloom’s Taxonomy or Bloom’s Revised Taxonomy) scientific or mathematic problems and findings

Benefits for Students: Advantages for Participating in Lessons

The advantages for student participation are grounded in the use of higher order thinking skills as students are more:

Focused – students are more attentive in class when they participate. Why? Few students actually listen to teacher lectures or demonstrations of how to solve math problems or explanations of science concepts – passive learning. However, their attention and focus are increased when students:

  • question the importance of specific procedures for solving a math problem or data collection techniques in a scientific investigation.
  • use the language of math or science as they communicate using correct terminology for explanations, asking questions, and responding to your questions. This helps them link terms with definitions.
  • connect concepts and link big ideas in science or math during open class discussions.
  • are more likely to complete homework or other assignments when they understand you will ask questions, using random student selection, regarding these assignments.

Engaged – achieved though stimulating student interest by causing conflict with their prior knowledge and experiences, along with assessing their understanding. This can be achieved as you ask higher order thinking open-ended questions, for example:

  • How does … affect …?
  • What causes …?
  • What are the differences (or similarities) between …?
  • Why is … important?
  • How does … relate to what we have learned before about …?
  • Explain why you agree or disagree about …?


Student Participation Techniques

Using time tested teaching techniques, along with the integration technology; students are more focused and engaged at all ability levels. Examples include:

Case Studies – groups defend or assail a point of view regarding a specific concept or idea. This approach is beyond simple knowledge, comprehension, or application of a concept. Students are required to analyze, synthesize, and evaluate evidence and use their findings to support their point of view. Examples include:

  • Stimulating Critical Thinking through a Technological Lens – use of technology tools stimulates both inquiry and critical thinking skills. How? Students are exploring, thinking, reading, writing, researching, inventing, problem-solving, and experiencing the world outside their classroom.
  • Integrating Podcasts in Science and Math – student groups create a podcast of a specific potion of a unit or chapter studied in class. The podcasts are posted on a class blog or Wiki and are downloadable for students to use when studying for tests. Each podcast should be limited to five to six minutes to promote a clear and concise summary of key concepts, ideas, and problem solving.

Visual Webs – groups use concept maps, graphic organizers, or Venn diagrams to make connections between related concepts or ideas. Students construct their visual webs using Google Docs, Bubbl.us, Keynote, Power Point, Inspiration, Prezi, or Kidspiration.

Student Blogs – provide opportunity for students to participate in collective math or science problem solving. Students spend more time on accuracy and information provided when they are aware their classmates will provide input or feedback, not just their teacher.

Brainstorming – students contribute ideas as a collaborative process for providing possible solutions to problems or situations requiring analysis, synthesizing, or evaluation of findings or conclusions.

Active learning has its foundation in constructivist and inquiry-based teaching and learning techniques. The building blocks for these techniques involve active student participation by talking, listening, writing, reading, investigating, problem solving, and reflecting.

Of course these ideas, techniques, and strategies are only a beginning. Contributions to this discussion are welcomed.

Online Learning: Web-Based Science and Math Centers

Web-Based Learnng Centers

Web-Based Learnng Centers

For a web-based learning to be truly effective it must be interactive. This means that it is not just a reformatted canned science lesson or math worksheets placed on the web.

The web-based activity is inquiry-based and incorporates the full features available on the web – interactivity between computer and student.

The learning activity must engage student critical thinking skills by using the inquiry process.

Scientific Inquiry: Web-Based Learning Centers

Web-based science and math learning centers are ideal for group inquiry-based activities using interactive online resources and in class supporting materials in designated stations.

These stations are designed to support as many learning styles as possible within the context of the learning center.

Web-based learning centers work with one or multiple computers; of course more computers are better.

Creating a web-based learning center stations for students requires the following setup:

  • one or more computers
  • hands-on/minds-on science investigations
  • print resources

The best designed web-based learning centers in science and math focus on one specific scientific concept at a time, such as:

  • five senses
  • animal cells
  • anatomy
  • cloud types
  • energy
  • geometric shapes
  • symmetry
  • graphing
  • equations

Sample web-based learning center using the Water Cycle include:

  • One station containing books on the water cycle
  • One or more computer station(s) with two or three predetermined interactive websites for students’ to research water cycle.
  • One minds-on investigation station that allow students to visualize the water cycle in action and help answer questions they developed (developed prior to and during investigation)
  • One hands-on/minds-on station that allow students to design a simple experiment to complete additional research
  • One or more stations for analyzing findings
  • One or more stations for preparation of presentation of findings using education technology tools

Before students begin the learning center, students determine questions they want answered regarding the water cycle.


Online Learning: Technology Based Resources

Select a concept and then find two or three web-based resources to support student interactivity with the concept.

There are many options to find resources and directories that support this effort, examples are:

Water Distiller: A Solar Experiment

Posted by David Wetzel

Solar Distiller

Solar Water Distiller

Students use hands-on inquiry based science to investigate the water distillation process using solar energy.

The purpose of this experiment is to determine if pure water can be distilled from dirty water.

Materials: (Per Group of Students)

1 Large Clear Plastic Container
1 Small Glass
1 Small Rock
1 Tablespoon
2 Tablespoons of Dirt
Clean Water
Duct Tape
Clear Plastic Wrap

Hands-On Procedures:

1. Tape the empty glass to the bottom of the large clear bowl, open side up.
2. Add water to a point below the glass opening, ensure clean water does not enter glass.
3. Add 2 tablespoons of dirt to water and stir.
4. Cover opening of bowl with plastic wrap and place small rock in center.
5. Place completed bowl setup in sunny location or use a heat lamp if sunny location is not available.

Inquiry Based Hypothesis Development and Discussion:

1. Students predict if the outcome of the experiment during construction of their Solar Water Distiller.
2. Students make observations of their Solar Water Distiller for 5 days.
3. Students discuss the outcome: Was their hypothesis supported? What evidence do they have to support their findings? What would happen if salt was used instead of dirt? What about sugar?
