Embedded blended learning within an Algebra classroom: a multimedia capture experiment

摘要

This two-group, pretest-posttest, quasi-experimental study compared secondary students' learning of Algebra Ⅱ materials over a 4-week period when identical instruction by the same teacher was delivered through either embedded blended learning (treatment group; n = 32) or a live-lecture classroom (control group; n = 24). For both groups, instruction was delivered in a normal classroom setting. A math test and a student survey were used to measure students' learning of Algebra Ⅱ and satisfaction with the instruction. Students in the treatment group showed significantly greater gains in Algebra Ⅱ test scores and evaluated their learning experiences significantly more positively than did the control group. The great majority (80%) of students in the treatment group preferred the embedded blended learning over traditional live lectures for future learning of math. Students' responses to open-ended survey questions suggested that students in the treatment group appreciated the: (a) ability to control the pace of instruction; (b) new role of the classroom teacher; (c) lack of distraction in the blended learning environment; and (d) accessibility of the embedded multimedia lessons outside the classroom. This study suggests that screen-capture instructional technology can be used towards establishing a teacher-based, embedded blended learning environment within a secondary algebraic classroom.
