What Was I Thinking?: Facilitating Metacognition
and Mindfulness in My Classroom
Leslie G. FatumHWP 2010
Questions
What strategies can I employ to get my students to write about their own thinking,
every day?
How do I explicitly teach metacognition?
What can I do to develop mindfulness in my students through looking closely, exploring possibilities and perspectives, and introducing
ambiguity?
The nature of science is inquiry. However, as a teacher of science during the past two years, the state and district standards and curriculum mandates have stressed “mastery” of abstract and arbitrary knowledge bytes that are conceptually and contextually disconnected from my students’ prior science education, as well as having little or no relevance to their day-to-day experiences.
Problem
After months of asking my students to “think” about the concepts, rather than just memorizing trivial minutiae or benchmark practice exam answers, I finally came to the realization that they not only did not know what they were thinking -- they literally were not thinking about what we were discussing.
From this realization, I began my quest to uncover strategies and routines that would lead them to this disposition of mindfulness. A first step is to practice “visible thinking” (metacognition) through activities that require the students to not only actively think about what is occurring, but to identify and describe their thoughts about it.
Realizations
Metacognition requires that students have knowledge about, awareness of, and control over their learning (Baird and White, 1996; Koba and Tweed, 2009).
Conceptual change requires that teachers elicit various student explanations for the teacher and the student to consider. Students need to reflect on and discuss their understandings, compare and contrast explanations, consider arguments to support or contradict explanations, and choose possible explanations based on the evidence they have gathered (Hewson 1996; Hipkins et al., 2002; Koba and Tweed, 2009).
Thinking is invisible, but there are ways that teachers can make it visible to their students, helping them to become more metacognitive and to see high school as more about exploring ideas than memorizing content (Koba and Tweed, 2009).
Rationales
Concept cartoons about evolution from San
Diego State University (developed by Dianne Anderson and Kathleen Fisher, 2002 www.biologylessons.sdsu.edu/cartoons/concepts.html)
Paper and pen/pencil
Materials
They were created by Brenda Keogh and Stuart Naylor in 1991 They feature cartoon-style drawings showing different
characters arguing about an everyday situation They are designed to intrigue, to provoke discussion and to
stimulate scientific thinking They may not have a single "right answer" Concept cartoons stimulate students to discuss their ideas,
including those that are normally reluctant to do so. This gives teachers access to those ideas. It also gives students access to each other's ideas, which may prompt them to reconsider their own.
The visual cartoons and minimal written text provide a valid assessment strategy for students with poor literacy skills, reluctant learners, and ESOL students.
Concept cartoons appear to reduce the risk of fear of giving a "wrong" response.
Concept Cartoons: What are they, and how are they used?
1. Practice developing your own thinking log +/- concept cartoon.
2. Using pre-crafted cartoons on evolution, record your first thoughts about a statement by the character that you feel best expresses your own views on the meaning of the concept.
3. Share responses in your group. 4. Revise your responses if your thinking
changes. 5. Share out with the class.
Protocol
Use bullets, not sentences Go with your gut reaction Write a brief rationale for your thinking Share your thoughts with your group After you are done, you can add different
thoughts from a new perspective (up to five total)
If you want to, draw a concept cartoons with your characters expressing their thought in ONE simple sentence
Selected students will share with class
Jot down your FIRST thoughts
CompetitionIn biology, competition is one of
the many symbiotic relationships occurring in nature. Same or different members of species
compete for resources, especially for limited natural resources.
AdaptationThe adjustment or changes in
behavior, physiology, and structure of a population of organisms to
become more suited to an environment over time.
Dominance(Of, or pertaining to) An allele or a
gene that is expressed in an organism’s phenotype, masking the effect of the recessive allele
or gene when present. Phenotype: The expression of a
particular trait, for example, skin color, height, behavior, etc.,
according to the individual’s genetic makeup and
environment.
Evolution
In order for evolution to occur, there must be genetic variation. Genetic variation brings about
evolution. Without it there will be no evolution. There are two major mechanisms that drive
evolution. First is natural selection. Individuals with advantageous traits are more likely to
reproduce successfully, passing these traits to the next generation. This kind of evolution driven by
natural selection is called adaptive evolution. Another mechanism involves genetic drift, which
produces random changes in the frequency of traits in a population. Evolution that arises from
genetic drift is called neutral evolution.
FitnessIn biology, Darwinian fitness or
simply fitness of a biological trait describes how successful an
organism has been at passing on its genes. The more likely that an
individual is able to survive and live longer to reproduce, the higher is
the fitness of that individual.
Selection
It is the process by which heritable traits that increase an organism’s chances of
survival and reproduction are more favoured than less beneficial traits.
Originally proposed by Charles Darwin, natural selection is the process that
results in the evolution of organism.
