So you have scored a mid-level high school, which makes you lucky enough to be able to teach students with quite a range of abilities. Some will happily strike up a conversation with you in the hall, while others will reply “Errr, um, etto…” to questions as simple as “How are you today?” This is the happy challenge you face.
The majority of these students do go on to higher education, some to University and others to one of the many two-year colleges. For these students English will prove necessary to a greater or lesser degree in their post-High School education. For others who see themselves going into careers with less English usage (or none at all), learning “Eigo” is often not something they see as a priority. For them, making classes interesting will help them stay focused and want to learn.
Some schools have specialist courses in addition to the general academic course, such as home economics, social welfare, phys ed, etc. In these streams, you may have the opportunity to teach some English specific to the students’ interests. For example, at Inami High School, we taught the home economics class about different recipes in English, and then got them to write their own original recipes. Naturally, catering to the students own interests make the classes more fun for everyone involved.
The best advice I can give you is to work closely with your JTE’s and take some time to get acquainted with your students’ varying levels. Then you can start to make their (and your) school life more interesting with some fantastic lessons.
