The current study examines the effects of digital scaffolding on the English literacy of fourth- and sixth-grade students. A total of 1085 native English-speaking and language minority students from 25 treatment classes and 20 control classes across three school districts participated in this study for one school year. Treatment students read their English language arts and social studies text in visual-syntactic text format (VSTF) on their laptops and control students read the regular block format of the textbook either on their laptops or in print. Observations and interviews revealed that VSTF reading facilitated instruction processes and student learning in reading activities. The results of California Standard Tests (CST) before and after the treatment revealed that sixth-graders who received syntactic scaffolding outperformed control students on the composite CST score. In particular, reading in VSTF benefited the treatment students in three CST sub-categories: word analysis, written conventions and writing strategies. This study suggests that future research should investigate instructional strategies that support reading and writing development of adolescents, including at-risk students, using syntactic scaffolding. 相似文献

Undergraduate biology education is often viewed as being focused on memorization rather than development of students’ critical-thinking abilities. We speculated that open-note testing would be an easily implemented change that would emphasize higher-order thinking. As open-note testing is not commonly used in the biological sciences and the literature on its effects in biology education is sparse, we performed a comprehensive analysis of this intervention on a primary literature–based exam across three large-enrollment laboratory courses. Although students believed open-note testing would impact exam scores, we found no effect on performance, either overall or on questions of nearly all Bloom’s levels. Open-note testing also produced no advantage when examined under a variety of parameters, including research experience, grade point average, course grade, prior exposure to primary literature–focused laboratory courses, or gender. Interestingly, we did observe small differences in open- and closed-note exam performance and perception for students who experienced open-note exams for an entire quarter. This implies that student preparation or in-test behavior can be altered by exposure to open-note testing conditions in a single course and that increased experience may be necessary to truly understand the impact of this intervention. 相似文献

Dialogic reading, when children are read a storybook and engaged in relevant conversation, is a powerful strategy for fostering language development. With the development of artificial intelligence, conversational agents can engage children in elements of dialogic reading. This study examined whether a conversational agent can improve children's story comprehension and engagement, as compared to an adult reading partner. Using a 2 (dialogic reading or non-dialogic reading) × 2 (agent or human) factorial design, a total of 117 three- to six-year-olds (50% Female, 37% White, 31% Asian, 21% multi-ethnic) were randomly assigned into one of the four conditions. Results revealed that a conversational agent can replicate the benefits of dialogic reading with a human partner by enhancing children's narrative-relevant vocalizations, reducing irrelevant vocalizations, and improving story comprehension. 相似文献

Writing is critical for college and career readiness, yet secondary students in America are not good writers (National Center for Education Statistics, 2012). Unfortunately, researchers know relatively little about secondary students’ writing skills, and even less about their digital writing. In this study, we explored prior computer use, keyboard activity during writing, and their relations to writing achievement using the 8th grade 2011 National Assessment of Educational Progress writing assessment, the first national computer-based writing assessment for U.S. secondary students. We found that prior computer use predicted students’ writing skills directly (0.08) and indirectly (e.g., keypresses, 0.14) via keyboard activity during the test. We found differential effects for certain groups including current English learners and disadvantaged students. We also found a small positive interaction effect of prior use and keypresses on writing. That is, the benefits of prior computer use for school writing and the value of students’ additional keypresses on writing achievement were amplified when both were present.

Addressing high demand for developmental math instruction and low rates of successful completing of the developmental coursework, with cost and space constraints, has been an ongoing challenge for postsecondary institutions. With advances in online instructional technology, particularly those based on artificial intelligence, web-based instruction is increasingly considered as a way to alleviate these burdens. This is among one of the first efforts that uses a quasi-experimental design to compare the academic outcomes of students who take a developmental mathematics course in a blended setting that combines face-to-face instruction with an online intelligent tutorial system, ALEKS, to the academic outcomes of students who take the same course in a fully online setting. Results suggest that students receiving online-only instruction perform worse on the final exam and receive lower course grades. However, a cost-effectiveness analysis suggests that fully online instruction has both a lower cost per student enrolled and a lower cost per student passing the course. 相似文献

This paper examines a US foreign aid project to promote use of new technologies in Egyptian education. Though the project sought to improve teaching and learning, an examination of implementation indicates how goals of Westernization ended up taking precedence. These included a focus on bringing Egyptian educators to the US and on showcasing US hardware and software. This underlying emphasis on Westernization weakened the project’s potential contribution to educational improvement. However, grass roots Egyptian teacher educators found ways to assert their own voices in the project through small‐scale and locally appropriate uses of technology. 相似文献

The practice of reading is rapidly moving from print to screen. Young children are not immune from this trend; indeed, many children's principal literacy experiences occur using iPads and other handheld digital devices. This transition raises important questions about how the emergence and development of literacy might change in these new environments. This paper reviews research to date on e-reading, both in the pre-tablet and tablet era, within the context of what we know more generally about literacy development. We then propose topics for future research and discuss methodological issues related to the investigation of these topics. Our goal is to spark further discussion about how to study young children's literacy development in the emerging e-reading era. 相似文献

Primary literature is essential for scientific communication and is commonly utilized in undergraduate biology education. Despite this, there is often little time spent training our students how to critically analyze a paper. To address this, we introduced a primary literature module in multiple upper-division laboratory courses. In this module, instructors conduct classroom discussions that dissect a paper as researchers do. While previous work has identified classroom interventions that improve primary literature comprehension within a single course, our goal was to determine whether including a scientific paper module in our classes could produce long-term benefits. On the basis of performance in an assessment exam, we found that our module resulted in longitudinal gains, including increased comprehension and critical-thinking abilities in subsequent lab courses. These learning gains were specific to courses utilizing our module, as no longitudinal gains were seen in students who had taken other upper-division labs that lacked extensive primary literature discussion. In addition, we assessed whether performance on our assessment correlated with a variety of factors, including grade point average, course performance, research background, and self-reported confidence in understanding of the article. Furthermore, all of the study conclusions are independent of biology disciplines, as we observe similar trends within each course. 相似文献

In planning educational technology initiatives, the concerns of many stakeholders are typically taken into account, including the concerns of administrators, teachers, parents, and employers. The perspective of students are recognized as valuable, but not often queried or considered. This paper explores the opinions of K-12 students about a one-to-one laptop programme implementation through content analysis of 362 blog postings made by these students expressing their thoughts on the topic at three time points in two years. Employing a bottom-up coding strategy, this paper identified seven themes that represented students’ opinion of technology use in schools: more efficient and productive learning, tools for better writing, access to information, engagement with new media, remaining relevant in a technological world, share and learn from peers, and individualized and differentiated instruction. This study suggested that, when new technology tools are used in schools, students should not only be viewed as learners but also be considered as real writers with valuable opinions. Students also should be provided the opportunity to write for an authentic purpose and audience using diverse forms of digital media. 相似文献

What constitutes learning in the 21st century will be contested terrain as our society strives toward post-industrial forms
of knowledge acquisition and production without having yet overcome the educational contradictions and failings of the industrial
age. Educational reformers suggest that the advent of new technologies will radically transform what people learn, how they learn, and where they learn, yet studies of diverse learners’ use of new media cast doubt on the speed and extent of change. Drawing on recent
empirical and theoretical work, this essay critically examines beliefs about the nature of digital learning and points to
the role of social, culture, and economic factors in shaping and constraining educational transformation in the digital era.
