Fourth, the evaluation method.
Usually, the experimental results account for 70% of the final grade of this experimental course, and the experimental report results account for 30% of the final grade of this experimental course.
Usually, the experiment mainly examines the difficulty of designing the experimental circuit, the ability of connecting and debugging the circuit and solving problems, and whether it can meet the design requirements.
The experimental report mainly examines the students' mastery of the theoretical knowledge involved in the experiment, whether they can correctly understand and analyze the conclusions and phenomena drawn from the experiment, whether they can reasonably explain the problems in the experiment and correctly judge the success or failure of the experiment.

Part II: Curriculum design.
First, the nature and purpose of curriculum design
This course not only requires students to acquire theoretical knowledge of electronic technology and master theoretical design methods, but also cultivates students' ability to integrate theory with practice. The course design link of this course is to make students have a deeper understanding of the theoretical knowledge they have learned and improve their ability to analyze and solve problems by designing, building and debugging circuits themselves.
Second, the basic requirements of curriculum design
1. Master the use of commonly used small and medium-sized integrated circuit chips (such as logic gates, decoders, data selectors, counters, registers, etc.). ).
2. Master the basic design steps of logic circuits (including combinational logic circuits and sequential logic circuits) and the implementation method of the whole circuit.
3. Have certain ability to analyze, find and eliminate common circuit faults.
4. Be able to correctly use commonly used electronic instruments (such as multimeter, oscilloscope, time sequence signal generator, etc.). ).
5. Independently write a course design report with theoretical analysis and design scheme demonstration, and verify whether its design is correct by building circuits and debugging.
Three. Design theme, content and requirements (16 class hours)
Design and Implementation of 1. Digital Frequency Meter
This topic requires the design and implementation of a digital frequency meter with optional design parameters, which is used to measure the frequency of signals and display it in decimal digits.
2. Design and implement independent experimental projects.
This project requires the use of digital circuit knowledge to realize the self-designed project design function and debug successfully, and the design difficulty is equivalent to 1 design topic.
Choose one of the above topics.
Third, the curriculum design schedule
Draft the revised design report 3 weeks before the experiment, open the project report 4 weeks, and conduct the experiment 5 weeks.
Fourth, the curriculum design report writing norms
After completing the design task, in the final stage of curriculum design, it is necessary to summarize all the design work, write a complete and standardized design report, and submit it to the instructor within the specified time. The course design report needs a complete format, as shown below:
The paper is divided into three parts-the first part, the text and the last part.
(1) Preface: This part includes title, author (unit), abstract and key words.
The topic should properly and accurately reflect the content of the paper.
The author unit should write the name and class number of the whole school, college (department).
It is a summary and brief description of the content of the paper, which should include the innovative ideas and achievements of the research topic, its theoretical value and practical significance.
Keywords should be accurate and concise.
(2) Text: This part, including introduction, text and conclusion, is the formal part of the paper.
As the first paragraph of the paper, the introduction should briefly explain the background and significance of the topic, the problems to be solved and the main work content.
The text is the main part of the paper, which should include the overall scheme design, scheme demonstration and realization, data analysis and processing, experimental effect and theoretical analysis.
As the last paragraph of the paper, the conclusion is the final and overall evaluation of the research. In the conclusion, we should make clear the innovation and achievements, technical key and technical difficulties, social and economic value and the prospect of research direction of this topic. The conclusion should be accurate, complete and concise.
Note: the main part of the paper can be titled (see the attached example for the specific format). The first paragraph of the article is an introduction, the last paragraph is a conclusion, and the middle paragraphs are the text. There is no need to add subheadings such as introduction, text and conclusion.
(3) The rear part:
1, reference
References are attached as an appendix to the paper. Reference refers to the literature materials that inspire and help you in the process of research and paper writing, including works, papers and web pages. The column writing format of references is as follows:
[1] author. Name of the work. Place of publication: publishing house. Date of publication.
[2] author. Title of the paper. Name of periodical or magazine. matter of prime importance
[3] Web page (URL)
……
The above [1] and [2] are the serial numbers of the literature, in which [1] is the column writing of the book and [2] is the column writing of the paper.
2. Experience:
In terms of content, you can put forward your own opinions and suggestions on how to carry out and carry out this comprehensive training.
(4) Requirements:
(1) written independently by individuals, one for each person,
② Words: the main part should be no less than 3,000 words, the abstract should be 150-200 words, and the keywords should be 3-6.
③ Typesetting: Typesetting on A4 paper. The margins are: 25mm up and down, 35mm left and right, 30mm pairs;
Paragraph spacing and word spacing: standard; Line spacing: single-line spacing; Page number: the bottom is centered; Author (unit) accounts for one line, the previous line and the next line (primary four); There is a blank line between the main part, the front part and the back part; No cover, no header, footer and page borders.
④ Font size selection: (see attached example).
Verb (abbreviation for verb) performance assignment
The assessment results of curriculum design are evaluated according to excellent, good, medium, passing and failing.
Have a thorough understanding of the design tasks, be able to complete the tasks specified in the design content comprehensively, correctly and independently, draw design results, and submit accurate, complete and standardized design reports on time, which can be rated as excellent; According to the requirements of the design task, it can successfully complete the task and achieve results, and submit a relatively complete and qualified design report on time, which can be rated as good; According to the design requirements, the hardware circuit is connected, the task requirements are basically completed, and the design report that meets the requirements is submitted, which can be rated as medium; Basically completed the design objectives, but not perfect enough, there may be some minor defects. With the help, can complete the task requirements, submit the design report, can be rated as qualified; Failure to complete the specified requirements and tasks and failure to submit the design report shall be deemed as unqualified.
