The United States curriculum reform movement has recently started in each area of science education. Theserious problem. The schools in the United States are not only facing a lack of offerings within science curricula but alsolow enrollment in science courses, especially in physics, chemistry, and earth science. This trend resulted in lowperformances on international achievement tests including TIMSS and PISA. This paper introduces the efforts to solveexisting problems through curriculum reform; including ChemCom, BioCom, EarthComm, and Active Physics. In thispaper, a discussion is presented to show how the curricula can help address the status quo in science education. Morethe scope and sequence of the reform movement. EarthComm was chosen because it was released based on thedevelopment of the National Science Education Standards (NRC, 1996). Consequently, EarthComm became a curriculumthat espoused the visions of the Standards, which has been guiding the reform of the US curriculum. At the end of thispaper, two research outcomes of the EarthComm curriculum implementation in schools are discussed in terms of studentlearning and differences from conventional curricula..........national science education standards, earth systems education, EarthCom, curriculum reform
