    abstract     = {Summary: In reality, learner-centered instruction's real worth has not been exposed when implementing instructions using elementary mathematics textbooks developed for the execution of learner-centered instruction, since the 7th national curriculum were revised in 1997. Therefore, some characteristics were examined. It would be expected that instructional material is developed which is reflected on the characteristics in revising next national curriculum and developing elementary mathematics textbook.},
