the correlation coefficient for the relationship of 21st century skills on students' perceptions
towards teaching and learning of physics is 0.58, namely the strength of the relationship between two variables is at
medium level as defined by Alias (1997). As the value of correlation r obtained is positive, it can be concluded that
the slope is positive. This shows the correlation is directly proportional to, or we can say that if their perception
towards teaching and learning of Physics is positive, then the skill of the 21st century will also increase. The
correlation coefficient obtained for digital age literacy on students’ perceptions teaching and learning Physics (0.30),
inventive thinking (0.40), effective communication (0.27), high productivity (0.25) and spiritual values (0.55).
Based on the numerical value presented, the relationship of 21st century skills components towards students’
perceptions on teaching and learning Physics were moderate and low as defined by Alias (1997).
