AlviusTinambunan 3 / 7 Apr 17, 2016 #1How have you contributed to solving a challenge and to implementing change or reform?I have an ability in problem solving, by using computer or an idea to simplify the system but made it more efficient and effective. I focused on data and several factors i found in my workplace. One of my work is , I made a system where a lot of administration can be linked in one application, so when we click one subject or lesson in the application, we can see several features. each features link to other files according to the structure we made. The files could be the score, Lesson Plan, Syllabus and several problems. Maybe the application is not using an advance program, but it works and useful. Other application i made is a test simulation, I named it Tesla ( Test simulation) . This application can be use to test a student using time based test, and it application use only a picture so it will save the paper. The idea of the test is using database that is Microsoft Access and the language i use is Pascal in Delphi 7. So each problem have a time according to the difficulty of the problem. the time showed in program will count down by itself when the application was starting. maybe it will make student nervous and scare, but it will teach them how to use time effectively and not underestimate the problem. In my teaching method, i always focus on concept and practical examples. For example when i teach about Newton Law, i will use equipment that we can see in our daily life such as, broom, table, bucket, even pencil. I will tell them something seem contradiction but its correct according to the law of nature. Why i focused on concept? in my place, the students is enforced to memories the formula, and i realized that its not effective and the student don't have their own life skills but good scores.
