learning and teaching strategies


A.JIGSAW
The jigsaw classroom is a cooperative learning technique with a three-decade track record of successfully reducing racial conflict and increasing positive educational outcomes. Just as in a jigsaw puzzle, each piece--each student's part--is essential for the completion and full understanding of the final product. If each student's part is essential, then each student is essential; and that is precisely what makes this strategy so effective.
Here is how it works: The students in a history class, for example, are divided into small groups of five or six students each. Suppose their task is to learn about World War II. In one jigsaw group, Sara is responsible for researching Hitler's rise to power in pre-war Germany. Another member of the group, Steven, is assigned to cover concentration camps; Pedro is assigned Britain's role in the war; Melody is to research the contribution of the Soviet Union; Tyrone will handle Japan's entry into the war; Clara will read about the development of the atom bomb.
Eventually each student will come back to her or his jigsaw group and will try to present a well-organized report to the group. The situation is specifically structured so that the only access any member has to the other five assignments is by listening closely to the report of the person reciting. Thus, if Tyrone doesn't like Pedro, or if he thinks Sara is a nerd and tunes her out or makes fun of her, he cannot possibly do well on the test that follows.
To increase the chances that each report will be accurate, the students doing the research do not immediately take it back to their jigsaw group. Instead, they meet first with students who have the identical assignment (one from each jigsaw group). For example, students assigned to the atom bomb topic meet as a team of specialists, gathering information, becoming experts on their topic, and rehearsing their presentations. We call this the "expert" group. It is particularly useful for students who might have initial difficulty learning or organizing their part of the assignment, for it allows them to hear and rehearse with other "experts."
Once each presenter is up to speed, the jigsaw groups reconvene in their initial heterogeneous configuration. The atom bomb expert in each group teaches the other group members about the development of the atom bomb. Each student in each group educates the whole group about her or his specialty. Students are then tested on what they have learned about World War II from their fellow group member.
What is the benefit of the jigsaw classroom? First and foremost, it is a remarkably efficient way to learn the material. But even more important, the jigsaw process encourages listening, engagement, and empathy by giving each member of the group an essential part to play in the academic activity. Group members must work together as a team to accomplish a common goal; each person depends on all the others. No student can succeed completely unless everyone works well together as a team. This "cooperation by design" facilitates interaction among all students in the class, leading them to value each other as contributors to their common task.
B.Think, Pair, Share
The think, pair, share strategy is a cooperative learning technique that encourages individual participation and is applicable across all grade levels and class sizes. Students think through questions using three distinct steps:
1.      Think: Students think independently about the question that has been posed, forming ideas of their own.
2.      Pair: Students are grouped in pairs to discuss their thoughts. This step allows students to articulate their ideas and to consider those of others.
3.      Share: Student pairs share their ideas with a larger group, such as the whole class. Often, students are more comfortable presenting ideas to a group with the support of a partner. In addition, students' ideas have become more refined through this three-step process.

Why Is It Important?

Students need many opportunities to talk in a linguistically rich environment. Researchers have found that students' learning is enhanced when they have many opportunities to elaborate on ideas through talk (Pressley 1992).
The think, pair, share strategy increases the kinds of personal communications that are necessary for students to internally process, organize, and retain ideas (Pimm 1987).
In sharing their ideas, students take ownership of their learning and negotiate meanings rather than rely solely on the teacher's authority (Cobb et al. 1991).
Additional benefits of using the think, pair, share strategy include the positive changes in students' self-esteem that occur when they listen to one another and respect others' ideas. Students have the opportunity to learn higher-level thinking skills from their peers, gain the extra time or prompting they may need, and gain confidence when reporting ideas to the whole class. In addition, the "pair" step of the strategy ensures that no student is left out of the discussion. Even a student who is uncomfortable discussing his or her ideas with the whole class still has an audience in this step. Finally, while the strategy may appear to be time-consuming, it makes classroom discussions more productive, as students have already had an opportunity to think about their ideas before plunging into whole-class conversations.

How Can You Make It Happen?

The think, pair, share strategy is ideal for teachers and students who are new to collaborative learning. It can be used in a variety of contexts. However, to be effective, students must consider a question or issue. It could be a complex question, such as, "What do you think were the key issues that led to World War I?" It could be a more straightforward request, such as, "Create a pattern that could be described as 'a, b, a, b.'"
As students consider the question or issue, they should derive some benefit from thinking about it further with partners, such as when there are multiple correct answers to a question. For instance, in the previous example, students could provide many examples of "a, b, a, b" patterns and seeing multiple answers will reinforce this concept. On the other hand, providing students with questions that have only one correct response, such as, "What is 5 + 2?" soon becomes tedious to students, as there is not much to share with partners or the whole class.
The "think" step may require students merely to be quiet for a few moments and ponder their thoughts about the question. They may write some thoughts in response to the question.
Some teachers find it helpful to set a time limit for the "think" and "pair" steps of the strategy. If you choose to do this, be sure to give students an idea of how much time they will have. Remember to allow sufficient time during the "pair" step to allow both students to talk about their thoughts.
In the "share" step of the strategy, students can share their ideas in several ways. One way is to have all students stand, and after each student responds, he or she sits down, as does any student with a similar response. This continues until everyone is seated. Another way is to move quickly through the class, having students respond quickly, one after the other, or to have a class vote. Responses can be recorded on an overhead projector or on a graphic organizer for future discussions. Another variation is to stop after the "pair" step, and have students write their ideas. Collect students' responses and assess any problems in understanding.
C.SQ3R
SQ3R is a reading strategy formed from its letters: SQ3R will help you build a framework to understand your reading assignment.
Before you read, Survey the chapter:
    • the title, headings, and subheadings
    • captions under pictures, charts, graphs or maps
    • review questions or teacher-made study guides
    • introductory and concluding paragraphs
    • summary
Question while you are surveying:
    • Turn the title, headings, and/or subheadings into questions
    • Read questions at the end of the chapters or after each subheading
    • Ask yourself, "What did my instructor say about this chapter or subject when it was assigned?"
    • Askyourself, "What do I already know about this subject?"
       Note: If it is helpful to you, write out these questions for consideration. This variation is called SQW3R
When you begin to Read:
    • Look for answers to the questions you first raised
    • Answer questions at the beginning or end of chapters or study guides
    • Reread captions under pictures, graphs, etc.
    • Note all the underlined, italicized, bold printed words or phrases
    • Study graphic aids
    • Reduce your speed for difficult passages
    • Stop and reread parts which are not clear
    • Read only a section at a time and recite after each section
Recite after you've read a section:
    • Orally ask yourself questions about what you have just read, or summarize, in your own words, what you read
    • Take notes from the text but write the information in your own words
    • Underline or highlight important points you've just read
    • Reciting:
      The more senses you use the more likely you are to remember what you read Triple strength learning: Seeing, saying, hearing Quadruple strength learning: Seeing, saying, hearing, writing!!!
Review: an ongoing process
Day One
    • After you have read and recited the entire chapter,
      write questions in the margins for those points
      you have highlighted or underlined.
    • If you took notes while reciting, write questions for the notes you have taken in the left hand margins of your notebook.
    • Complete the form for a critical reading review


Day Two
    • Page through the text and/or your notebook to re-acquaint yourself
      with the important points.
    • Cover the right hand column of your text/note-book
      and orally ask yourself the questions in the left hand margins.
    • Orally recite or write the answers from memory.
    • Develop mnemonic devices for material which need to be memorized.
      Make flash cards for those questions which give you difficulty.
Days Three, Four and Five
    • Alternate between your flash cards and notes and test yourself
      (orally or in writing) on the questions you formulated.
    • Make additional flash cards if necessary.
Weekend
    • Using the text and notebook, make a Table of Contents - list all the topics and sub-topics you need to know from the chapter.
    • From the Table of Contents, make a Study Sheet/ Spatial Map.
    • Recite the information orally and in your own words as you put the Study Sheet/Map together.
    • As you have consolidated all the information you need for this chapter, periodically review the Sheet/Map so that at test time
      you will not have to cram.
D.The Story Face
Appropriate Grade Level: Elementary

Procedures/Steps:

  • The Story Face is an adaptation of story mapping that also uses a visual framework for understanding, identifying, and remembering elements in narrative text.


The Story Face is constructed by:
  1. making the eyes: two circles representing the setting and main characters
  2. eyelashes: specific descriptors and secondary characters
  3. nose: problem
  4. mouth: comprises a series of circles representing the main events that lead to the solution
