  • Drinking From A Cup, Removing One’S Own Garments, Washing And Drying Hands

    1. 1. Assessment
    2. 2. “ Studies suggest that many physical educators fail to assess their students’ motor behavior properly. The major reason for this is lack of training.”
    3. 3. Guidelines for Assessment <ul><li>Why do you want to assess your students/patients? </li></ul><ul><li>What variables do you plan to assess? </li></ul><ul><li>Which tests purport to assess the variables that you have identified? </li></ul><ul><li>How will you prepare for collecting the data? </li></ul>

    5. 5. Why Assess? <ul><li>Screening </li></ul><ul><ul><li>To identify needs </li></ul></ul><ul><ul><li>To determine if an individual requires further testing, additional programming, or instruction </li></ul></ul><ul><li>Program content </li></ul><ul><ul><li>Plan the content of a particular program </li></ul></ul>

    17. 17. Instructor Preparation and Data Collection <ul><li>You must think through and even pilot (test run) your assessment procedures prior to administering the test to a target population </li></ul>
    18. 18.

Formal vs. Informal Assessment <ul><li>When assessment is performed in an informal manner, the student is not generally aware that an observation is being made </li></ul><ul><li>Playbased assessment </li></ul><ul><ul><li>Children are involved in free play within an approved area, but in the presence of an adult facilitator </li></ul></ul>
    22. 22. Formal vs. Informal Assessment <ul><li>Playbased assessment </li></ul><ul><ul><li>Facilitator plays along and models the child's play behavior </li></ul></ul><ul><ul><li>Later, the facilitator will coax the child into exhibiting new movements </li></ul></ul><ul><ul><li>During this time, an evaluation is being conducted </li></ul></ul><ul><ul><li>Videotaping is recommended </li></ul></ul>

    29. 29. Product- vs. Process-Oriented Assessment <ul><li>Component approach assessments not feasible to use with large classes </li></ul><ul><ul><li>Takes too much time </li></ul></ul><ul><ul><li>Appropriate for small classes </li></ul></ul><ul><li>Total body approach assessments more feasible with large classes </li></ul>
