Chapter 11 Strategies Fostering Thinking in the Science Classroom How to Read This Chapter • In this chapter we will explore teaching strategies that facilitate student thinking. Some teachers refer to these as “active learning strategies” because of their influence on high levels of student engagement. The first set of strategies will be explored in terms of their impact on students’ ability to think critically and creatively. We’ll develop some teaching strategies in the context “microteaching” experiences that will enable you to focus on specific abilities such as using advanced organizers, questioning, and promoting student engagement. We’ll explore powerful ideas to help student talk, read and write as they learn science. We will also explore strategies that foster independent and collaborative thinking among secondary students. Culture of Learning: Language & Vygotsky Talking Science Writing Science Reading Science Invitations to Inquiry • What teaching strategies can be used to foster critical and creative thinking among students? • How can interactive teaching strategies foster thoughtful dialogue with and between my students? • What feedback might a colleague in a “peer-coach” role offer to enhance my teaching abilities? • How does research on reading, writing, and discourse in science education contribute to the development of a constructivist classroom? • How can projects be used to enhance thinking in science?

Holistic Thinking Critical Thinking Designing Experiments Predicting Classifying Observing Creative Thinking Testing Hypotheses Intuiting Seeking Alternatives Inferring Generating Alternatives Dreaming Measuring Visualizing Imagining Interactive Teaching Strategies • Critical and creative thinking require that students be actively involved. The following “interactive” teaching skills will foster this: – Advance Organizers – Creating Stimulating Environment – Art of Questioning – Using Examples – Positive Learning Environment – Closure & Making Transitions • Select one of the above, and write a lesson plan that incorporates the skill into a lesson in biology or physics. The Art of Questioning • Do an inquiry into the Art of Questioning: – Why is it an art? – How would you categorize the questions listed on page 334? – What is the difference between a low-inquiry question and a highinquiry question? – What are some examples of lowand high-inquiry questions? Write a few out. – How does using “wait time” influence critical and creative thinking in the science class? – What suggestions does Blosser make in the article on Questions? (See the Companion site) What does this picture tell you about the moon? Who made the Footprint?--How would classify these questions? Inquiry 11.1: Microteaching • • • • Microteaching is scaled down teaching. You will use it to implement one or more the interactive teaching strategies. Prepare a 5 minute lesson and use it to focus on one or more of the teaching strategies (advance organizers, questioning, using examples, etc.). Teach the lesson to a small group of peers; use the video tape to reflect and make changes in the lesson for a re-teach episode. How successful were you? Culture of Learning: Language and Vygotsky • Language is tool for the expression of information and ideas. In the science classroom, we’ll explore: – Talking science – Reading science – Writing science • Who is Lev Vygotsky? Important keys to learning are described in this chapter. Lev Vygotsky • • • • • • Russian psychologist Higher-level learning take place on the “social plane.” The social context and language are the essence of learning. Distinguished between “scientific” and “spontaneous” concepts. School is the environment for the dialog between these two types of concepts. Coined the term “zo-ped” or zone of proximal development--the place where student’s rich experiential knowledge (spontaneous) meets the systematic world (scientific). Language & Its role in Science Teaching Talking Science Reading Science Writing Science Talking Science • Students need to talk about their ideas in science class. Here are some strategies: – Structured Controversies – Open-Ended Questions – Science Talks – Telling the Stories of Science Global Warming: Is the Earth really heating up? A hungry Earth: Can the Earth feed its human population? Crisis in the Ocean: How polluted is the Ocean? The garbage problem: What is the best way to manage waste? Chemicals on the highways: How can hazardous waste be managed? Extinction: How endangered is life on the planet? Design a Structured Controversy on any one of the above topics, and prepare a handout Outlining how you would involve middle school students in the “debate.” Structured Controversy Reaching a Decision-teams present a unified position on the controversy leads to Structured Controversy Reverse Position-teams swap sides & debate new position Learning Positions leads to leads to Discussion among the two teams at each debate table assign students to leads to Each Team Presenting Its Position • The Cycle shown here is a cooperative learning debate model. Students are divided into teams of four. With in each team, students are divided into pairs. Each pair is assigned a learning position (one side of the issue). • Topics should have two clear positions. Once a topic is identified, resources should be gathered and identified for teams to do their research. The previous slide lists a few suggested topics. Reading Science • Enhancing students’ reading abilities in science can be assisted via: – Listening – Coming to Terms-The Vocabulary Problem – Reading for Meaning (K-W-L strategy) – Semantic Mapping Sample Lesson 11.1: Earthquakes Using the K-W-L Strategy • This is an example of a content lesson that utilized a reading strategy, K-W-L. • The emphasis is on having students read for meaning. To do this, the K-W-L strategy creates an active reading environment. – K-What do they Know? – W-What do student Want to know? – L-What did students Learn? Earthquake map, California Writing Science Sample Lesson 9.2: Crusty (Rock) Writing In this geology lesson, student observe the physical properties of rocks and then use the “data” they have collected to write a poem. Procedures Have students gather rocks as part of field trip, or bring in enough rocks from the local scene so that each student will have one to observe. Stimulus All students have a rock on their desk. Discuss what the students can observe about a rock based on each of the senses. Have a student recorder write key words on the board or on chart paper, such as: Sight---size, shape, and color Hearing---rattle, scraping Taste---mineral content, dirt Touch---shape, roughness, smoothness, unevenness, bumps Smell---sweet fragrance, earthiness Have students fold a sheet of composition paper in thirds, labeling one section for each sense, and the sixth one entitled Other Ideas. Ask students to observe their rocks and to jot down notes about what they observe. Activity: After have had time to observe and write notes, tell them that they can use their observation to write an ode to their rocks. Tell them that an ode is a song that begins, "Oh " and that is usually praises a person. The can begin their poem with "Oh rock...." and speak to their rock as a person, using personification. • There are many ways to help students express their ideas through writing, thereby bringing thought to consciousness. These include: – – – – – Web writing Science logs Letter writing Science newspapers Story writing Sample Lesson 11.3: Learning Log • Read the section on the use of learning logs. • Describe how you will set up the use of the learning log in your course. • How will you assess learning logs? Project-Based Teaching • Project-Based teaching supports high-level thinking and problem solving. Here you will find a collection of project-based ideas to implement in the classroom. They are organized into: – Life Science Projects – Physical Science Projects – Earth Science Projects The Mars Egg Drop project challenges students to construct a cargo system to safely protect an egg dropped from a high place. Students design their vehicle and then are taken to a place where they can drop it at least 10 meters. Click on the icon above to go to other project ideas.
