IMPROVING EXPERIMENT DESIGN SKILLS: USING THE JOKO TINGKIR PROGRAM AS A LEARNING TOOL OF TSUNAMI TOPIC
Abstract
Students are rarely given an opportunity to think deeply about experimental design or asked to develop experimental skills on their own. Without participating in these endeavors, they are often unaware of the many decisions necessary to construct a precise methodology. This article describes the Joko Tingkir Program as an Early Warning Tsunami, and how we have used this program as a learning tool for physics teacher candidates to improve their experimental design skills. The Joko Tingkir computer program has implemented a Tsunami Faulting Model (TFM). The TFM uses the principle that the tsunami is affected by the length and width of earthquake rupture. Both can be represented by the duration of rupture (Tdur) or Exceed 50 second duration (T50Ex) and the dominant period (Td). The TFM has been implemented by the Joko Tingkir computer program. When students are given a simple method using the Joko Tingkir program - such as the tutorial, observation of seismic station distribution, seismograms of the earthquake, equipment and software for this experiment, measurement of P time onset and determination of Tdur, Td and T50Ex - it allows them to focus exclusively on improving experiment design skills as indicated by significantly improved gain scores. Based on the gain analysis it can be inferred that the experiment design skills can be improved by implementation of Joko Tingkir Program as a Learning Tool of Tsunami Warning in the learning process
