Abstract

The purpose of this research had two specific objectives were 1) to Construction and validate the Measurement Instruments of the Media Literacy Skills in the 21st Century for Secondary Students; 2) to establish grade norms of the Measurement Instruments of the Media Literacy Skills in the 21st Century for Secondary Students. Using multi-stage random sampling method, research sample for test validation and norms construction consisted of 503 Secondary Students who studied in Wangnoi District Opportunity expansion school year 2020. The Construction of the Measurement Instruments aim in five factors: 1) Access skill 2) Analyze skill 3) Evaluate skill 4)Create skill 5) Participate skill. Each behavior indicate consisted of seventy and two situational question.
The significant findings were as follows:
1. The content validity of the Construction of the Measurement Instruments, investigated by calculating the item objective congruence index (IOC), were in the range 0.60 – 1.00
2. The item Difficulty and Discrimination index were in the range 0.44 – 0.69 and 0.34 – 0.92 respectively
3. achieved Kuder-Richardson (KR-20) reliability, test reliability = 0.97
4. The construct validity of Measurement Instruments, investigated by confirmatory factor analysis, revealed that construct validity of the Measurement Instruments of the Media Literacy Skills in the 21st Century.
5. The local norms for the Measurement Instruments of the Media Literacy Skills in the 21st Century in the form of normalized T-score range T26 – T69
6. The manual of the Measurement Instruments was suitable, easy understand, and fully important composition.
