Efforts by K-12 schools to give every student a laptop computer increased student achievement and gave a modest boost to their 鈥�21st-century skills,鈥� concludes a first-of-its-kind meta-analysis of 15 years鈥� worth of research studies.

鈥淚t鈥檚 not like just providing a laptop to every student will automatically increase student achievement, but we find that it鈥檚 the first step,鈥� said , an assistant professor of counseling, educational psychology, and special education at Michigan State University.

Using statistical techniques to analyze already-completed studies, Zheng and her colleagues found that 1-to-1 laptop programs, on average, had a statistically significant positive impact on student test scores in English/language arts, writing, math, and science. The limited number of rigorous quantitative studies available to analyze means that further analysis is warranted, but the findings are clearly a good sign for 1-to-1 proponents, Zheng said.

A further review of 86 additional papers, meanwhile, found some modest evidence of other positive benefits associated with giving laptops to students, including increased student technology use; more student-centered and project-based instruction; greater student engagement; and better relationships between students and teachers.

The analysis focused solely on 1-to-1 laptop efforts. The researchers cautioned that their results are not generalizable to other devices such as tablets, desktop computers, and smartphones.

The new findings run counter to the skepticism about educational technology expressed by many researchers and practitioners. A raft of prior studies, for example, has shown that even when technology is present in classrooms, teachers are slow to transform their practice, instead using technology primarily to make administrative tasks and existing forms of instruction more efficient.

The new analysis has the potential to reshape the debate about ed-tech鈥檚 impact, said Elliot Soloway, a computer science professor at the University of Michigan who has spent decades studying classroom technology.

鈥淭his is one of those definitive studies that comes along every 20 years,鈥� Soloway said. 鈥淪chools are going to use [the findings] to justify the move to one-to-one.鈥�

Rapid Growth of 1-to-1

One-to-1 student computing was first introduced to K-12 schools in the United States in the late 1990s. In 2002, Maine became the first state to launch a statewide program.

The : In 2013 and 2014 alone, schools purchased more than 23 million laptops, tablets, and Chromebooks for use by students and teachers in the classroom (and sometimes at home).

Generally, the goal is to enable teachers and software to deliver more personalized content to students, to boost students鈥� technology skills, and to empower children to do more complex and creative work.

Several high-profile 1-to-1 disasters resulting from poor purchasing plans, bad planning, and a lack of clear academic vision have raised questions for schools about the wisdom of the approach, however.

And . A 2009 survey by the National Center for 91制片厂视频 Statistics, for example, found that classroom technology was used for practice of basic skills far more often than for design and creation. A recent study by the Organization for Economic Cooperation and Development found that countries where 15-year-old students use computers most in the classroom scored the worst on international math and reading tests.

In an attempt to definitively determine the impact of K-12 1-to-1 initiatives, Zheng and her colleagues reviewed 96 journal articles and doctoral dissertations published between January 2001 and May 2015.

Just 10 of those studies met the researchers鈥� criteria for inclusion in the statistical meta-analysis of 1-to-1 laptop initiatives鈥� impact on student achievement, reflecting the still-very-limited research base on student computing initiatives.

鈥淎 disproportionate amount of the research to date on this topic consists of small case studies in one or a handful of schools,鈥� Zheng and her colleagues wrote in their study, titled ,鈥� published in the academic journal Review of 91制片厂视频al Research. Still, there were enough historical findings to conclude that 1-to-1 laptop programs helped improve students鈥� academic achievement at statistically significant levels in English/language arts, writing, math, and science. The impact on reading was not statistically significant.

However, the effect of using laptops, overall, was noticeably less than the effect of other established interventions, such as smaller class sizes or individual tutoring.

The results are 鈥渟mall but noteworthy,鈥� Zheng said.

Interpret With Caution

The researchers also looked beyond test scores, reviewing 86 additional studies that did include an empirical examination of 1-to-1 laptop initiatives鈥� impact in K-12 schools, but did not include an experimental design and/or quantitative results. Among the findings from that review:

• A 1-to-1 laptop environment often led to increased frequency and breadth of student technology use, typically for writing, Internet research, note-taking, completing assignments, and reading.
• Students used laptops extensively throughout the writing process, expanding the genres and formats of their work to include writing for email, chats, blogs, wikis, and the like.
• Student-centered, individualized, and project-based learning appeared to increase in at least some instances of 1-to-1 laptop rollouts.
• Student-teacher communications (via email and Google docs, for example) and parental involvement in their children鈥檚 school work increased in some instances.
• Students expressed 鈥渧ery positive鈥� attitudes about using laptops in the classroom, as findings consistently showed higher student engagement, motivation, and persistence when laptops were deployed to all students.
• Students鈥� technology and problem-solving skills improved and their ownership of their own learning increased, according to some evidence.
• There were mixed findings on whether 1-to-1 laptop programs helped overcome inequities among students and schools.

Those results should be interpreted with caution, the researchers said, because they tended to rely on observation, survey, and interview data.

Beyond Test Scores

鈥淭here was a wide consensus in the studies we reviewed that use of laptops promotes 21st-century learning skills,鈥� the authors write. 鈥淗owever, studies rarely attempted to operationalize and systematically measure the growth of 21st-century skills in laptop students compared with control students.鈥�

Leslie Wilson, the CEO of the One-to-One Institute, a nonprofit that consults with schools and districts, said she was 鈥渢hrilled鈥� to see the new research, though she cautioned that educational leaders shouldn鈥檛 leap to conclude that going 1-to-1 is enough on its own to increase student achievement.

For such a program to be effective, she said, schools must focus on crafting comprehensive plans that cover everything from infrastructure to curriculum to pedagogy to professional development.

And the real benefits of giving every student access to a computer, contended Soloway of the University of Michigan, come when schools move from 鈥渋nstructive鈥� to 鈥渃onstructive鈥� learning, or from 鈥渢eaching kids to remember something to teaching them how to figure something out.鈥�

To best measure the extent to which that change is taking place, Zheng said, researchers and educators will have to look beyond standardized-test scores.

She hopes the new research will prompt further efforts to develop assessments for students鈥� digital literacy skills, as well as their creativity, independence, and leadership.

鈥淢any of the benefits of 1-to-1 laptop programs are not detected by standardized tests,鈥� Zheng said. 鈥淔or the many programs whose purpose is to help students be a better 21st-century citizen, we need to develop and use corresponding measurements.鈥�
