The objectives of this re
search was to improve students asking question
ability and mathematics achievement at class VII E of SMP Muhammadiyah 1
Purwokerto using Cooperative Learning of Numbered Heads Together (NHT).
The subjects of this Class Action Research were 30 students of V
II E of SMP
Muhammadiyah 1 Purwokerto. The research was conducted in three cycles.
Asking questions ability data were obtained from observation while students
achievement data were
obtained from evaluation test. Meanwhile, asking
questions ability data wer
e obtained from asking frequency. The result showed the
asking frequency from Cycle I were 37 times, Cycle II improved to 76 times and
Cycle III also improved to 82 times. The students mostly about knowledge
questions in Cycle I
and Cycle II. However, they
mostly deliver aplication
questions in Cycle III. For asking technique, the average of cycle I was 3.7,
improved to 6.5 in Cycle II and improve again to 7.1 in Cycle III. Students‟
mathemathics achievement data also improved consecutively in three cycles.
The
average score in Cycle I was 52.83, improved to 76.93 in Cycle II and improved
in Cycle III to 86.85. it can be concluded that Cooperative Learning of Numbered
Heads Together (NHT) could improved students‟ mathematics achievement and
asking question a
bility in at class VII E of SMP Muhammadiyah 1 Purwokerto.
