Models

  1. 1. OBJECTS , SPECIMENS & MODELS
  2. 2. OBJECTS <ul><li>Objects are samples of real things, tangible and is complete in itself. </li></ul><ul><li>E.g: a book, syringe with needles thermometer, stethoscope etc… </li></ul>
  3. 3. REPLICA <ul><li>IS A FULL SIZED COPY OF AN OBJECT . It looks , feels and acts like the objects itself. </li></ul>
  4. 4. REPLICA <ul><li>ADVANTAGES </li></ul><ul><li>Gets to know the finer points </li></ul><ul><li>Multisensory approach in learning </li></ul><ul><li>DISADVANTAGES </li></ul><ul><li>Problems regarding their storage </li></ul><ul><li>Can be used for small groups </li></ul><ul><li>May get damaged easily </li></ul>
  5. 5. SPECIMENS <ul><li>A specimen is a part taken as an example of whole or a category of like things so chosen to represent the whole category. </li></ul>
  6. 6. Advantages of specimens <ul><li>Specimens gives direct real life experience. </li></ul><ul><li>Clear cut images </li></ul><ul><li>Concrete experience </li></ul><ul><li>Motivates for further learning </li></ul>
  7. 7. Disadvantages of specimens <ul><li>Collecting specimens is difficult. </li></ul><ul><li>Needs specialized skills in preserving. </li></ul><ul><li>Expensive preserving agents. </li></ul><ul><li>Needs proper handling </li></ul>
  8. 8. <ul><li>Students gets the first hand information by looking at them or handling them. </li></ul>
  9. 9. MODELS <ul><li>A model is a three dimensional recognizable imitation of a real object. </li></ul><ul><li>It can be same size / larger / smaller than the actual one. </li></ul><ul><li>It can be seen, handled and operated from a number of angles. </li></ul>
  10. 10. Models can be used in relation to: <ul><li>Size: various sizes </li></ul><ul><li>Time: from past / future </li></ul><ul><li>Physical inaccessibility: places we cannot visit </li></ul><ul><li>Unusable reality: when real material cannot be studied ( human eye, lungs) </li></ul><ul><li>For simulations ( cpr) </li></ul><ul><li>Process ( eg. Gastric suction) </li></ul>
  11. 11. ADVANTAGES <ul><li>The size can be adjusted as needed. </li></ul><ul><li>Distance and time do not become as limitations. </li></ul><ul><li>Can explains concepts, structures ,working parts etc… </li></ul><ul><li>Simulates reality </li></ul><ul><li>Enables participation of the class </li></ul>
  12. 12. LIMITATIONS <ul><li>Costly </li></ul><ul><li>Needs more storage space </li></ul><ul><li>Useful for small group </li></ul><ul><li>Need talent to prepare </li></ul>
