Abstract (Summary)

Providing students with necessary intervention in the instruction of mathematics can be accomplished through the use of digital resources. Schools reaching a one-to-one (one device for every student) status have the ability to implement a digital intervention on a broad scale. For the purpose of this study, mixed methods research afforded an in-depth investigation into the impact of Khan Academy (digital intervention) embedded in a one-to-one program on student achievement, student perseverance with math, and teacher pedagogy within rural schools. The theoretical framework of educational technology integration known as Theoretical, Pedagogical, and Content Knowledge (TPACK) was woven into this study to answer the guiding research questions. While using Khan Academy in a one-to-one setting, participating students were tested twice a year utilizing the Measurement of Academic Progress (MAP) testing procedure provided by the Northwest Evaluation Association (NWEA). The testing data provided quantitative data for the study. In addition, interviews of teachers and administrators were conducted to reveal themes related to teacher pedagogy and student perseverance with mathematical problems. An analysis of MAP scores revealed that 9th- and 10th-grade high school students utilizing Khan Academy in a one-to-one program demonstrated significantly more growth when compared to national norms. The study involved 227 9th-grade and 114 10th-grade students from three rural high schools in the Pacific Northwest. Results from an analysis of means illustrated that each grade level demonstrated significantly greater growth when compared to national norms. When examined at the school level, each of the three sites once again exceeded growth norms. Further analysis of the interviews revealed a pedagogical shift directly related to the use of Khan Academy embedded in a one-to-one program. Themes related to the success of the program include the ability of Khan Academy to fill individual gaps and practice skills to mastery, the importance of student and teacher buy-in, and the ability for students to have daily, individual access to devices. Furthermore, the interviews revealed teachers and principals did not agree on whether Khan Academy impacts student perseverance; however, a theme related to Khan Academy’s ability to impact confidence with math did emerge. This study fills gaps in the existing literature regarding the academic and pedagogical impact of Khan Academy on teaching and learning. In addition, this study addresses a gap in the literature regarding rural schools’ use of a digital mathematical intervention program as a means of blended learning. Implications for educational policy can result from this study given the current political climate surrounding one-to-one and blended learning deployments. This study demonstrates that when one-to-one deployments are paired with the use of Khan Academy, student achievement can be positively impacted.
