DEVELOPMENT AND VALIDATION OF 21ST CENTURY SKILL INSTRUMENT IN PHYSICS

Arra Quitaneg Abaniel

Abstract


The study aimed to develop and validate 21st century skill instrument in Physics.  According to NCREL, & Metiri Group (2003) 21st century skills are composed of digital literacy, inventive thinking, effective communication and high productivity. The Partnership of 21st century skills and enGauge 21st century skills models were utilized in the study . The researcher initially  developed questions for four constructs namely digital literacy, inventive thinking, effective communication and high productivity. The developed instrument makes use of 4point Likert scale and had 45 questions. This instrument was validated by five experts in science education. For further validation, the instrument was administered to 143 senior high school students from Zambales, Philippines. Factor analysis resulted to five factors: a) information literacy, b) inventive thinking, c) effective communication, d) high productivity and e) leadership.  It was  found that the developed 21st century skill instrument in Physics  has established internal consistency with an over-all Cronbach alpha value of 0.901. Each factor was also found to meet the requirements of internal consistency having gained a Cronbach alpha values of 0.798, 0.862, 0.810, 0.706 and 0.705 respectively.  The validated 21st century skill instrument in Physics has 37 questions.
