Development of a digital literacy scale for high school students

Abstract

This research aimed to; 1) Analyze and synthesize the digital literacy scales for high school students. 2) Build and quantify the digital literacy Indicators for high school students. 3) Check the quality of the digital literacy Indicators for high school students. and 4) Create Norm score of digital literacy Indicators for high school students. The samples were 620 high school student in Secondary Education Office Service Area 27. Tools for data collection were Indicator presentation interview form, Indicator suitability and feasibility questionnaire, and a multiple choice digital literacy Indicators. Statistics used were percentage mean ( ) standard deviation (S.D.) KR-20, Confirmatory Factor Analysis : CFA), percentile, and T-score.

Major results of the study;

                   1) 4 of consist components of indicators measure the digital literacy indicators for high school students were : Accessibility, Analytical Ability, Assessment Ability, and Creative Abilities.

                   2) The digital literacy Indicators for high school students was 30-item, 4-choice, multiple choice measure, Consistency from 0.60 -1.00, Disciminant index between 1.03-4.77 and the reliability value was 0.984.

                   3) The examine a construct validity were based on theory of responses to three exam methods under the simulation study by Rudner's method. The difficulty (b) ranged from -2.243 to 2.284, mean values ​​were 0.074, and their chances of guessing correctly (c) ranged from 0 to 0, with all questions consistent with the model (2) situation 2 data (29_2PL10) found that this test had a power of discrimination (a) in the range of -2.085 to 2.178, the mean was 0.7691, the difficulty (b) was in the range of -0.514 to 2.747, and the mean. was 0.6402, and the probability of guessing test correctly (c) was in the range of 0 to 0, with all questions consistent with model, and (3) the simulation results of the 3^rd scenario (29_3PL10) found that this test was worth distinguishing power (a) ranges from -0.434 to 1.464 and averages 0.751, difficulty (b) ranges from -1.394 to 1.462 and averages 0.2000, and chances of guessing correctly (c) within range. -1.606 to 1.594 and mean 0.3618, with all questions consistent with model.

                   4) Overall of secondary school students had a very high level of digital literacy (64.70%).
