aku

aku hanya sebuah aku yang akan berakhir dengan sebuah keakuan dan hanya aku yang tahu tentang aku bukan engkau

"A dog is man's best friend." That common saying may contain some truth, but dogs are not the only animal friend whose companionship people enjoy. For many people, a cat is their best friend. Despite what dog lovers may believe, cats make excellent housepets as they are good companions, they are civilized members of the household, and they are easy to care for.
In the first place, people enjoy the companionship of cats. Many cats are affectionate. They will snuggle up and ask to be petted, or scratched under the chin. Who can resist a purring cat? If they're not feeling affectionate, cats are generally quite playful. They love to chase balls and feathers, or just about anything dangling from a string. They especially enjoy playing when their owners are participating in the game. Contrary to popular opinion, cats can be trained. Using rewards and punishments, just like with a dog, a cat can be trained to avoid unwanted behavior or perform tricks. Cats will even fetch!
In the second place, cats are civilized members of the household. Unlike dogs, cats do not bark or make other loud noises. Most cats don't even meow very often. They generally lead a quiet existence. Cats also don't often have "accidents." Mother cats train their kittens to use the litter box, and most cats will use it without fail from that time on. Even stray cats usually understand the concept when shown the box and will use it regularly. Cats do have claws, and owners must make provision for this. A tall scratching post in a favorite cat area of the house will often keep the cat content to leave the furniture alone. As a last resort, of course, cats can be declawed.
Lastly, one of the most attractive features of cats as housepets is their ease of care. Cats do not have to be walked. They get plenty of exercise in the house as they play, and they do their business in the litter box. Cleaning a litter box is a quick, painless procedure. Cats also take care of their own grooming. Bathing a cat is almost never necessary because under ordinary circumstances cats clean themselves. Cats are more particular about personal cleanliness than people are. In addition, cats can be left home alone for a few hours without fear. Unlike some pets, most cats will not destroy the furnishings when left alone. They are content to go about their usual activities until their owners return.
Cats are low maintenance, civilized companions. People who have small living quarters or less time for pet care should appreciate these characteristics of cats. However, many people who have plenty of space and time still opt to have a cat because they love the cat personality. In many ways, cats are the ideal housepet.
Why use Cooperative Learning?
Research has shown that cooperative learning techniques:
  • promote student learning and academic achievement
  • increase student retention
  • enhance student satisfaction with their learning experience
  • help students develop skills in oral communication
  • develop students' social skills
  • promote student self-esteem
  • help to promote positive race relations

    5 Elements of Cooperative Learning
    It is only under certain conditions that cooperative efforts may be expected to be more productive than competitive and individualistic efforts. Those conditions are:
    1. Positive Interdependence  
    (sink or swim together)
    • Each group member's efforts are required and indispensable for group success
    • Each group member has a unique contribution to make to the joint effort because of his or her resources and/or role and task responsibilities
    2. Face-to-Face Interaction
    (promote each other's success)
    • Orally explaining how to solve problems
    • Teaching one's knowledge to other
    • Checking for understanding
    • Discussing concepts being learned
    • Connecting present with past learning
    3. Individual
    &
    Group Accountability

    ( no hitchhiking! no social loafing)
    • Keeping the size of the group small. The smaller the size of the group, the greater the individual accountability may be.
    • Giving an individual test to each student.
    • Randomly examining students orally by calling on one student to present his or her group's work to the teacher (in the presence of the group) or to the entire class.
    • Observing each group and recording the frequency with which each member-contributes to the group's work.
    • Assigning one student in each group the role of checker. The checker asks other group members to explain the reasoning and rationale underlying group answers.
    • Having students teach what they learned to someone else.
    4. Interpersonal &
    Small-Group Skills
    • Social skills must be taught:
      • Leadership
      • Decision-making
      • Trust-building
      • Communication
      • Conflict-management skills
    5. Group Processing
    • Group members discuss how well they are achieving their goals and maintaining effective working relationships
    • Describe what member actions are helpful and not helpful
    • Make decisions about what behaviors to continue or change
    lass Activities that use Cooperative Learning
    Most of these structures are developed by Dr. Spencer Kagan and his associates at Kagan Publishing and Professional Development. For resources and professional development information on Kagan Structures, please visit: www.KaganOnline.com


    1. Jigsaw - Groups with five students are set up. Each group member is assigned some unique material to learn and then to teach to his group members. To help in the learning students across the class working on the same sub-section get together to decide what is important and how to teach it. After practice in these "expert" groups the original groups reform and students teach each other. (Wood, p. 17) Tests or assessment follows.
    2. Think-Pair-Share - Involves a three step cooperative structure. During the first step individuals think silently about a question posed by the instructor. Individuals pair up during the second step and exchange thoughts. In the third step, the pairs share their responses with other pairs, other teams, or the entire group.
    3. Three-Step Interview (Kagan) - Each member of a team chooses another member to be a partner. During the first step individuals interview their partners by asking clarifying questions. During the second step partners reverse the roles. For the final step, members share their partner's response with the team.

    4. RoundRobin Brainstorming (Kagan)- Class is divided into small groups (4 to 6) with one person appointed as the recorder. A question is posed with many answers and students are given time to think about answers. After the "think time," members of the team share responses with one another round robin style. The recorder writes down the answers of the group members. The person next to the recorder starts and each person in the group in order gives an answer until time is called.
     
    5. Three-minute review - Teachers stop any time during a lecture or discussion and give teams three minutes to review what has been said, ask clarifying questions or answer questions.
    6. Numbered Heads Together (Kagan) - A team of four is established. Each member is given numbers of 1, 2, 3, 4. Questions are asked of the group. Groups work together to answer the question so that all can verbally answer the question. Teacher calls out a number (two) and each two is asked to give the answer.
    7. Team Pair Solo (Kagan)- Students do problems first as a team, then with a partner, and finally on their own. It is designed to motivate students to tackle and succeed at problems which initially are beyond their ability. It is based on a simple notion of mediated learning. Students can do more things with help (mediation) than they can do alone. By allowing them to work on problems they could not do alone, first as a team and then with a partner, they progress to a point they can do alone that which at first they could do only with help.
    8. Circle the Sage (Kagan)- First the teacher polls the class to see which students have a special knowledge to share. For example the teacher may ask who in the class was able to solve a difficult math homework question, who had visited Mexico, who knows the chemical reactions involved in how salting the streets help dissipate snow. Those students (the sages) stand and spread out in the room. The teacher then has the rest of the classmates each surround a sage, with no two members of the same team going to the same sage. The sage explains what they know while the classmates listen, ask questions, and take notes. All students then return to their teams. Each in turn, explains what they learned. Because each one has gone to a different sage, they compare notes. If there is disagreement, they stand up as a team. Finally, the disagreements are aired and resolved.

    9. Partners (Kagan) - The class is divided into teams of four. Partners move to one side of the room. Half of each team is given an assignment to master to be able to teach the other half. Partners work to learn and can consult with other partners working on the same material. Teams go back together with each set of partners teaching the other set. Partners quiz and tutor teammates. Team reviews how well they learned and taught and how they might improve the process.
