32 CHAPTER 6 USING COMPUTERS 32 CHAPTER 6 USING COMPUTERS Document Transcript

  • 32 CHAPTER 6 USING COMPUTERS The assessments included three tasks which related to the use of comput- ers. These task sample some skills involved in using computers. Other computer skills will be sampled each year as part of the national monitor- ing programme, in a wide variety of curriculum areas. For instance, compu- ter use will be included in the 1997 assessments of mathematics, information skills and social studies. All three tasks were administered to both year 4 and year 8 students. The first two tasks presented here are released tasks, for which full details are given. The third task is a link task (to be used again in the year 2000), and therefore is not described in detail here). The results show that most Year 4 and year 8 students were able to use the computers effectively to complete simple tasks. It should be noted that this result was obtained after students completed an exercise which al- lowed them to practise standard procedures required to use the Macintosh Powerbook computers. The success rate was consistently higher for year 8 students than for year 4 students, but not by a large margin.
  • Chapter 6: Using computers 33 Mac Moves Approach: Station Level: Year 4 and year 8 Resources: Macintosh Powerbook 5300CS laptop computer with program Hypercard® Player; headphones; mouse; Hypercard® document Mac Moves. Questions/instructions % responses Three skills were considered essential for carrying out the assessment tasks using computers. The 4 year year Mac 8 Moves exercises were designed to ensure the students had the opportunity to acquire or practice those skills before beginning the assessed tasks. For each exercise the student heard their instructions through the headphones. At any time they could use the buttons at the bottom of the screen: Tell me… Hear the instructions repeated. Home Return to the main computer screen for choosing tasks. Again Have another go. Next Go to the next exercise. 1. Pointing and clicking an object. Point and click on each frog to make it jump into the water. Each frog made a noise as it appeared to jump into the water. Tell me. . . Home Again Next 2. Clicking into a text field and typing. Type in some words for the frog to say. Click on the line then type with the keys on the keyboard. Once the spoken instructions finished the words visible in the field on the screen disappeared. If the student clicked on the frog, the student heard a dis- gruntled noise and words appeared in the field saying Type me something to say! OK ‘don’t’ in various ways. If the student typed without clicking anywhere they heard a beep for each key typed and the verbal instruction “click on the line before typing any letters”. Tell me. . . Home Again Next Once they had typed in something, if they clicked OK then they heard the frog ‘speak’ whatever they had typed (using the Macintosh® speech technology). 3. Pointing with the fingertip part of the hand-shaped Hypercard® cursor. Click on the dark oval in the centre and then on each ring from the fat rings in the centre to the narrow rings on the outside. Use the pointed finger on the little hand on the screen to point before you click. As they clicked on each ring the colours (shades of blue and red) changed, and when they clicked on the smallest ring the screen flashed and they heard “Well done! You Tell me. . . Home Again Next were able to click even the smallest red oval!”
  • 34 NEMP Report 5: Technology 1996 Treasure Find Approach: Station Level: Year 4 and year 8 Resources: Macintosh Powerbook 5300CS laptop computer with program Hypercard® Player; headphones; mouse; Hypercard® documents Mac Moves (introductory exercises) and Treasure Find. Questions/instructions % responses year 4 year 8 Treasure Find opened with the screen below. The student heard their instructions through the headphones: Welcome to Find the Treasure. Remember, if you want to choose a word, move the hand over the word and push down the button on the top of the mouse. Start by choosing the word Start. The student was given a series of tasks such as the example above left, and ended at a final brightly coloured reward screen (above right), which varied depending on which words they had chosen. The End button returned the student to the main (Home) screen for choosing tasks, and was available at any time. Answered all questions 60 79 Completed answering questions on computer, but made one or more word knowledge errors 40 21 Did not complete the sequence of responses required 0 0 Commentary The results shows that all students were eventually able to enter the required series of re- sponses on the computer. The only errors were errors in selecting among options involving word knowledge rather than computer usage. View slide
  • Chapter 6: Using computers 35 Form Fill Approach: Station Level: Year 4 and year 8 Resources: Macintosh Powerbook 5300cs laptop computer with program Hypercard® Player; headphones; mouse; introductory Hypercard® document Mac Moves and Hypercard® document Form Fill. Questions/instructions % responses year 4 year 8 The form the students were to fill in was on 3 screens (left).There were no verbal instructions for this task. The student clicked the brightly coloured button to go to the next screen; the button on the final page returned the student to the main (Home) screen for choosing tasks. If the student typed without first clicking in a field they heard beeps for each key typed and a cue field appeared (visible second screen at left). Responded appropriately to all task components 57 70 Responded appropriately to most task components, but made one error 33 23 Incomplete response, or more than one error. 10 6 View slide
