This study aims to describe the difference in creativity and mathematics achievement between gifted students who were taught by Treffinger's learning and those who thought by the expository learning in trigonometry material. This study is a quasi-experiment using a pretest-posttest group design with a population of all gifted students in class X of a State Senior High School in Bali, Indonesia. The sample was established randomly. Observation sheets, pre-test, post-test, and student creativity questionnaires were used, all of which have been validated. The data were analyzed descriptively and inferentially with the paired sample t-test to test the mean difference of …

Using the nationally representative sample from the United States in the 2012 Programme for International Student Assessment (N = 7,429 students from 240 schools), I examined the relationship between teacher instructional practices and student mathematics achievement. To account for the multilevel structure of the data with students nested within schools, I used a two-level hierarchical linear model in the data analysis. Teacher instructional practices showed statistically significant effects on student mathematics achievement, even after controlling for socioeconomic status (SES) and sex at the student level and school mean SES and whether the school is public or private at the …
