| Summary: | 碩士 === 國立臺灣師範大學 === 工業教育研究所 === 89 === The purpose of this study is to devlop the teaching material of the digital logical practical units technical vocational high schools, and to design and make the pacticce equipment.
The first step of this study was to make literature review about subject matter development, next to make a survey for understanding teaching status of digital logic practice in schools; finally to develop a model for developing digital logic subject matter.
Using this model and the results of the survey, an outline and some sample units of digital logic practice subject matter based on CPLD and laboratory equipment were developed.
According to the results of this study, the content should include the usuge of logical experiment equipments, graphic editor and logical gates, combinational logic, adder and subtractor, multiplexer, demultiplexer, encoder, decoder, comparator, flip-flop and counter, shift register, VHDL language and special project.
The practice equipment developed in this study includes CPLD module, practice units, I/O expandable interface and power circuit.
The units that can be practiced on the equipment include following items:
1. 16 × LED
2. 8 ×8 dot-matrix display
3. A driver of stepping motor
4. 1×8 pin data switch
5. 4×pulse keys
6. 4×7-segment display
7. 2×oscillating circuits (555 oscillating circuit and crystal
oscillating circuit )
8. 5×8 pin expandable interface
The above practice units have already included digital logical practice material units. Practice units can be added into the equipment by using I/O expandable interface. Therefore the equipment is helpful to the students.
