This study explores the role of unconventional forms of classroom assessments in expanding minoritized students' opportunities to learn (OTL) in high school physics classrooms. In this research + practice partnership project, high school physics teachers and researchers co-designed a unit about momentum to expand minoritized students' meaningful…

Examines whether retesting: (1) affects achievement of students (N=95) grouped according to previous achievement in science; and (2) influences students to delay studying and perform at a low level on initial tests. Also examines whether procrastination of retested students is affected by their achievement level. (DS)

Determined differences between lecture-demonstration and small-group laboratory approaches on students' (N=74) chemistry achievement and attitudes toward science. Findings indicate that students taught by the laboratory approach achieved better on immediate/delayed posttests than students taught by lecture-demonstration method. More desirable…
