the bar chart above shows comparison of N-gain score of research indicators, the research conducted in two classes namely experiment class and control class
overall, the score is ranged between 0 – 1 and the indicators involved abstraction, generalization, decomposition, algorithm, and debugging. The score of experiment class shows higher than control class with algorithm indicator is the highest score, while in control class decomposition indicator is the highest score. The lowest scores of both classes are generalization indicator.
In detail, N-gain score of experiment class shows the fluctuated score from the abstraction 0,72, decrease into 0,61 in generalization and climb again into 0,76 and 0,77 and the last it decreased 0,62 in debugging. Besides, N-gain score of control class is abstraction 0,44, generalization 0,39, it is increase 0,62 in decomposition, algorithm 0,54 and climb slightly into 0,5 in debugging.
at the end, N-gain score of experiment class is higher than control class, it means that the research conducted in experiment class has significant impact.
