Questionnaire items need to be designed according to the research topics, such as online learning satisfaction, learning validity, etc., and the topics should be designed around two keywords: "satisfaction" and "learning effect".

Usually a keyword subordinate can have 4~7 questions, not too many. According to this logic, the two keywords only have 8~ 14 questions, and at the same time "satisfaction" and "learning effect" can be further divided into specific dimensions. For example, satisfaction can be divided into platform stability, interactive system, curriculum arrangement and so on, and so can "learning effect".

At the same time, add some background information questions of respondents, such as age, gender, occupation, etc.

If thinking tends to study the influence relationship, it is best to design the question as a scale question, which is convenient for linear regression analysis and other research in subsequent analysis.

A questionnaire generally includes: sample background questions+sample attitude questions+core research questions, and the above parts are basically acceptable.
