Past efforts to improve education have focused on curriculum and instruction. Some schools are pursuing more systemic year-round schooling and 4-day week reforms. The Waihe'e Elementary School and the Star of the Sea School, both in Hawaii, are implementing single-track plans for year-round schooling to improve academic achievement, social-affective behaviors, and community life (Waihe'e) and to provide flexibility in the core curriculum (Star of the Sea). Satisfaction remains high for 4-day school weeks in New Mexico and Colorado. Studies suggest that feared declines in academic performance have not occurred, with tentative evidence of improved achievement. In Oregon, 4-day week schools elicited positive responses from staffers, parents, and students. The saved time translated into increased savings, more instructional time, more time for extracurricular activities, and improved attendance. In Hawaii, the Ma'ili and Ha'aheo Schools implemented 4-day weeks with longer instructional days that have increased achievement and teacher, parent, and student interaction. Evidence suggests that year-round schooling can be successful depending on the reform context, and that 4-day weeks, in general, work in small/rural school districts. (Contains 14 references.) (TEJ)
