The data were collected from the series of four lessons in the fifth grade by teaching experiment methodology conducted following the professional development project implemented lesson study and open approach in Thailand. The results show that extension and integration sequence is an appropriate subject matter to generate lesson for problem-solving classroom. The sequence of lesson leads students to excitement, curiosity, confidence and intimacy in mathematics that are powerful effects of mathematical creativity. Students can produce the different and various ways to solve problems that indicate their divergent thinking.展开更多

Based on the discourse, the study is going to make an analysis of three versions of English textbooks for junior high school, including PEP, FLTRP and OUP. Through comparing the subject matter and the type of writing of the reading comprehension, the researcher is to provide some suggestions to users. Also, there are still some limitations, which can be improved in the future.展开更多
