In this study, we examine students' mathematical reasoning within a technological environment designed to support understanding of relationships between quantities with adjustable measuring units. In particular, we provide a cross-sectional snapshot of how 30 elementary students (Grades 3-5) engaged in a series of fraction-as-measurement tasks…

There is a recognized need to understand the current state of programming implementation in the Swedish compulsory school system. This study focused specifically on the implementation of programming in the school subject of technology for grades 4-6. In Sweden, the responsibility for choosing teaching and learning material lies with individual…

We present two types of validity evidence to support inferences and decisions about use of easyCBMs in relation to state testing programs. The first type involves the use of Benchmarks in reading to use in making predictions of performance on the Smarter Balanced (SB) test. These predictions can be made both well in advance (several months) or…

Zearn Math is a popular software platform for K-8 mathematics learning, designed to enable all students to successfully access grade-level content. RAND researchers collaborated with Zearn, the product's developer, to design this evaluation. Then RAND conducted the study independently, randomly assigning 64 schools in an urban Texas district to…

This study investigated the understudied area of virtual reality (VR) creation among elementary-aged youth, exploring their engagement in VR creation and the ways in which educators can facilitate this creative process. Using an embedded case study, the researcher examined how the youth visualize writing using the VR creation tool, CoSpaces. To…

This developmental research aims to: (1) examine the developmental processes of the application called MagicSpells, a haptically-enhanced, digital, vocabulary acquisition application design for learners with dyslexia, (2) investigate the structure and design of the application, and (3) analyze the results of the reviews and usability tests…

This dissertation consists of three papers. In each paper, I leverage a different quantitative method to study a downstream effect of technology on educational outcomes. In the first paper, I study the impact of an online math learning program on 3rd through 5th grade math achievement in Louisiana. Employing Zearn Math usage metrics and…

Personalizing the use of educational mathematics applets to fit learners' characteristics poses a great challenge. The present study adopted a unique approach by comparing personalization processes implemented by a machine to those implemented by a human teacher. Given the different affordances--the machine's access to historical log file data,…

A randomized controlled trial group design study funded by IES NCR Grant R305A090527 was conducted in which 16,307 3rd, 4th, and 5th grade students in 52 school grade-level clusters were randomly assigned to receive ST Math (program revision Gen3), a supplemental mathematics software instructional intervention, or to a business-as-usual…

This study is one of the first evaluations of independent (i.e., self-guided) practice in math in a developing country. We randomly assigned 4,461 students in grades 4-7 in "unaided" private schools across seven Indian cities who were using a computer-assisted learning software to: (a) a control group, in which they moved from one unit…

The purpose of this design-based research study was to provide a holistic perspective on the pedagogical and contextual factors of interactive mobile technology on English learners and investigate the theoretical potential of audio-video software interventions for second language acquisition. Specifically, the study explored current virtual…

Because students have often been conditioned as passive learners and receivers of knowledge, it can be difficult for them to persevere in solving authentic problems. Nevertheless, teachers must persist in preparing students as problem solvers and critical thinkers. In an urban inner-city neighborhood school in the southeast, students embarked on a…

This study aims to investigate the influence of story creation on young EFL learners' reading performance. Action research was adopted to examine the effects of two different story reading projects in a library setting in Taiwan. Each project comprised a group of 19 young EFL learner from Grades 4 to 6 (aged 10-12). The first group's activities…

This study investigated a new conversation-based assessment for English language learners. In this assessment, students converse with animated agents in natural language conversations to assess various aspects of English language learning. In a between subjects design, 31 students (N = 31) were asked questions by either the newly created system or…

Main idea and summary are essential elements of reading comprehension. We report results from Grades 4 and 5 student performance on two years of state-mandated standardized reading testing which indicate that students perform statistically significantly lower on main idea and summary questions on the tests than any other question category. In this…
