Parent Perception Survey on Computational Thinking 2018Back

Research Background

After May 2017, The Hong Kong Jockey Club Charities Trust commissioned the Public Opinion Programme (POP) of The University of Hong Kong again in July 2018 to conduct this “Parent Perception Survey on Computational Thinking 2018” targeting Cantonese-speaking parents whose child / children is / are studying in kindergarten, primary or secondary school. The objectives of the survey was to measure parents’ awareness of computational thinking and the “CoolThink@JC” project, and also compare some survey results of last year.

The research instrument used in this study was designed entirely by the POP Team after consulting The Hong Kong Jockey Club Charities Trust, while both POP and The Hong Kong Jockey Club Charities Trust had equal say in the final instrument. Moreover, fieldwork operations, data collection and data analysis were conducted independently by the POP Team, without interference from any party. In other words, although the content of the questionnaire mainly came from the commissioning organization, POP was given full autonomy to design and conduct the survey, and POP would take full responsibility for all the findings reported herewith.

Research Design

Telephone interviews were conducted by interviewers under close supervision. All data were collected by our interviewers using a Web-based Computer Assisted Telephone Interview (Web-CATI) system invented by the research team, which allowed real-time data capture and consolidation. To ensure data quality, on top of on-site supervision, voice recording, screen capturing and camera surveillance were used to monitor the interviewers’ performance.

Telephone numbers are randomly generated using known prefixes assigned to telecommunication services providers under the Numbering Plan provided by the Office of the Communications Authority (OFCA). Invalid numbers are then eliminated according to computer and manual dialing records to produce the final sample.

The target population of this survey was Cantonese-speaking parents whose child / children is / are studying in kindergarten, primary or secondary school. For landline sample, when telephone contact was successfully established with a target household, one eligible subject was interviewed. If more than one eligible subject had been available, selection was made using the “next birthday rule” which selected the person who had his/her birthday next. The survey was conducted during the period of 23 August to 7 September 2018. A total of 1,003 eligible subjects were successfully interviewed. The effective response rate of this survey was 53.8%, and the standard sampling error for percentages based on this sample was less than 1.6 percentage points. In other words, the sampling error for all percentages using the total sample was less than plus/minus 3.2 percentage points at 95% confidence level.
