Abstract

Computer programming subject is the most-feared subject by students because it is hard to learn. At present, various learning media for programming have been available; therefore, the learning process that used to be monotonous and challenging to learn has become exciting and easy to do. One of those media is the Website. Usability is a crucial aspect to be noticed for the users so they would be facilitated during the usage, acquiring the required knowledge, and be interested to always rely on the site in their learning process.

The score acquired from the rating given by familiar respondents only a bit higher compared to the unfamiliar respondents. The rating in the alphabet resulted in B or Good. It can be concluded that this computer programming learning site has met the usability criteria; therefore, it can be implemented as a learning medium that is feasible to be used by the users. Referring to such results, the web-based learning of computer programming as the alternative of pedagogic approach and teaching technique can be applied based on the psychological needs of students in their adolescence period, allowing them to collaborate, stimulating creative and analytical thinking in solving problems.
