The purpose of this study was to measure the children response to newly introduced lesson contents they never experienced before; they are skipping rope and double dutch. Preceded by introducing these skipping rope and Double Dutch skills to PE teachers through a short training, then all teachers are assigned to start teaching them to their children in school through PE lesson. On the other period, teams of observers were assigned to monitor the quick yield of the learning at schools, both in skill acquisition and the enthusiasm of children over the skills being introduced. The observation data then be analyzed through a simple procedure and the results were abstracted into the calculated format, to withdraw the conclusion. The result, much to our surprise, was so promising, since the children were so enthusiastic to these new activities. This result has ruined the old perception that children would have only interested in to formal sport skills activities. This could have happened simply that children also would also be so attracted by the new challenging activities.
