According to a large number of research and surveys, the most frequenl leisure activities for people in Taiwan are watching TV, reading, chatting, listening to radio and walking. This indicates that the quality of leisure time does not improve along with a highly developed economy. Recreational activity options are few. The types of leisure activities are not diverse and the quality and satisfaction of leisure time is low. Therefore, recreational education needs to be well planned and the concept of recreational education needs to be promoted, so as to solve these problems. Mr. Hang, Pao-te, the former head of the National Natural Science Museum, developed the concept of "cultural tourism era", stating that museums must break away from their traditional image and show diversity, which is necessary for the tourist business. Therefore, since its inauguration in November 1997, the National Science 8,: Technology Museum has been promoting itself as a recreational museum: take the example of the "museum classroom" in the National Natural Science Museum. In the winter break in 1999, it started a series of activities called "Science Expedition" included were topics about technology and life such as satellite, static electricity, low temperature, atmosphere, etc. Speakers were invited to give explanations and demonstrations. The public can either make an appointment or walk in. It provides more educational entertainment choices for people in their leisure time. During the summer break in 2001, "Summer of Ho-kingku" a scientific performance and exhibition, combined in-depth scientific principles of ecology and received enthusiastically positive remarks from children and parents. Motive The "Summer of Ho-kingku" had sixteen showings during July and August. Approximately 1,387 people participated, an average 87 people per show. It broke the record of past activities.
