Discussing ways of collaborative education between high schools and universities is one of the important targets in the Super Science High School (SSH) project. For producing better educational effects, it is desirable to collaborate between them as frequently as possible. However, frequent collaboration causes additional burden to the teacher on the university side as the result of effort made to prepare lectures and time for giving them. This study aims at reducing these burdens by adopting two approaches. Firstly, several graduate students were employed as teachers and the lectures were given by these teachers whilst paying attention to keeping the quality of the local forest research program. Secondly, a database lecture records was established so that several teachers can share what they conducted in the lectures with each other. As a result of the first approach, the burden of time required for implementation was not reduced sufficiently. However, the burden caused due to preparing for the lectures was eased. On the other hand, the trial establishment of the database showed its effectiveness from the viewpoint of sharing information on lecture content among several teachers, although some problems remain to be solved.
