This report examines theoretical and empirical issues related to the statistical power of impact estimates under clustered regression discontinuity (RD) designs. The theory is grounded in the causal inference and HLM modeling literature, and the empirical work focuses on commonly-used designs in education research to test intervention effects on…

Geometry is the study of shape and space. Without spatial ability, students cannot fully appreciate the natural world. Spatial ability is also very important for work in various fields such as computer graphics, engineering, architecture, and cartography. A number of studies have demonstrated that technology has an important potential to develop…

An alternating treatments design was employed to compare the effect of stimulus-stimulus pairing, standard echoic training, and a control condition on the vocal behavior of 3 preschoolers with autism. Data were recorded during pre- and postsession observations. During the stimulus-stimulus pairing condition, the experimenter's vocal model was…

The purpose of this qualitative case study was to document the writing choices of kindergarten children in an urban setting after planned experiences with transformational literature. This research involved nineteen kindergarten students who were participants through the naturalistic setting of routine classroom instruction. Four social issues…

In November 2005, the Council for Higher Education Accreditation (CHEA) invited its institutional members to submit applications for the newly established CHEA Award for Institutional Progress in Student Learning Outcomes. The award acknowledges outstanding institutional progress in developing and applying evidence of student learning outcomes…

Personalized curriculum sequencing is an important research issue for web-based learning systems because no fixed learning paths will be appropriate for all learners. Therefore, many researchers focused on developing e-learning systems with personalized learning mechanisms to assist on-line web-based learning and adaptively provide learning paths…

Prior work suggests that active experience affects infants' understanding of simple actions. The present studies compared the impact of active and observational experience on infants' ability to identify the goal of a novel tool-use event. Infants either received active training and practice in using a cane to retrieve an out-of-reach toy or had…

In a 10-day training, the efficacy of spelling pronunciations on German speaking 5th-graders' spelling skills for irregular words was examined. Poor spellers were less efficient in learning the spelling pronunciations than age-adequate spellers. On post-tests, 1 week after the last training day and between 5 and 12 weeks after post-test 1, poor…

A variety of experimental evidence indicates that the memory representation for multiplication facts (e.g., 6 [times] 9 = 54) incorporates bidirectional links with a forward association from factors to product and a reverse association from product to factors. Surprisingly, the authors did not find evidence in Experiment 1 of facilitative…

This study seeks to investigate the impact of symmetrical (S) and Asymmetrical (AS) scaffolding, which are two types of scaffolding, on students' reading comprehension achievement of English as a Foreign Language (EFL). The study was done in two phases: In the first phase after administering a Pre-test, 52 homogeneous intermediate students were…

This study focused on the potential for building 25 high-school students' word knowledge by using a mobile learning device and gaming app. Using a game as an instructional tool is a portable way for students to engage with content. The amount of vocabulary mastered after using the app on the mobile device was examined in relation to a pre-test and…

This quasi-experimental study tested the effect of the 3-2-1 strategy on English as a foreign language (EFL) learners' reading comprehension. A sample of Saudi EFL college-level students were randomly selected and divided into two groups: an experimental group (42 students) and a control group (43 students). Students of both groups took a reading…

Games Based Learning needs to be linked to good learning theory to become an important educational intervention. This study examines the effectiveness of a collection of computer games called Neurogames®. Neurogames are a group of computer games aimed at improving reading and basic maths and are designed using neuropsychological theory. The…

The field of English language education has seen developments in writing pedagogy, moving from product-based to process-based and then to genre-based approaches. In Vietnam, teaching secondary school students how to write in English is still lagging behind these growing developments. Product-based approach is commonly seen in English writing…

National testing standards have increased pressure on school personnel to identify and implement instructional practices that facilitate the academic achievement of at-risk students. No Child Left Behind legislation currently mandates that reading programs at the middle school level receiving federal funding must use scientifically validated…
