The Role Of Computer Algebra Systems In Mathematics Teaching At Upper Secondary School, Wendy Johnstone
The Role Of Computer Algebra Systems In Mathematics Teaching At Upper Secondary School, Wendy Johnstone
Theses : Honours
Computer algebra systems are programs that manipulate both symbols and numbers and so can reduce the tedium of algebra in the same way calculators can reduce the time and work involved in arithmetic. Some systems combine a wide ranqe of mathematical functions with graphing capabilities. As such they have the potential to reduce the time students spend calculating algorithms, allowing more time for concept development, which is enhanced by the ability of the program to concurrently represent mathematical functions graphically. Originally computer algebra systems were only developed for mainframe computers, but in recent years several systems have become available for …
Computer-Aided Drafting/Design In Technical Drawing In W.A. Secondary Schools, Edmund V. Beagley
Computer-Aided Drafting/Design In Technical Drawing In W.A. Secondary Schools, Edmund V. Beagley
Theses : Honours
This study was conducted with the intention of identifying what effects may have occurred within upper school Technical Drawing in W.A. high schools following the recent introduction of Computer-Aided Drafting/Design (CAD). With CAD being in its infancy in W.A. high schools it was decided that this study should attempt to answer four specific questions:- i) Were there any problems experienced by Technical Drawing teachers following the introduction of CAD? ii) Are there any educational benefits to either students or teachers to be derived from the introduction of CAD? iii) What methods of teaching and evaluating CAD generated drawings were being …
The Effect Of A Vee-Mapping Strategy On Students' Perceptions Of Laboratory Activities, Sonia J. Hueppauff
The Effect Of A Vee-Mapping Strategy On Students' Perceptions Of Laboratory Activities, Sonia J. Hueppauff
Theses : Honours
Practical work is considered important for learning science, by teachers and science educators. This acceptance though, has been reported as based on intuition rather than evidence (Atkinson & White, 1961). A significant proportion of class time is occupied with doing practical work. It is evident that in a majority of situations, students commence laboratory activities unsure of their aim, the procedure they are going to carry out, or that experimentation is a way of forming knowledge (Moreira, I 960; Novak & Gowin, I 964). Vee-maps (Novak & Gowin, 1 964) are one way of making laboratory work more meaningful. That …
Secondary Students' Difficulties With Designing A Controlled Experiment, Bradley E. Watson
Secondary Students' Difficulties With Designing A Controlled Experiment, Bradley E. Watson
Theses : Honours
This research investigation was conducted to identify the difficulties encountered by secondary science students in the design of a controlled experiment. These difficulties were illuminated by studying the combination of knowledge, skills and strategies employed by experts. Three categories of individuals were used in the study, Year 10 science students, Year 12 science students and science lecturers who had completed doctoral studies in their fields. There were six subjects interviewed in each category. Each of the subjects were given a task which involved thinking aloud while planning a controlled experiment. When the subjects had completed the task, they were asked …
