The study focused on the effects of the CAL system constructed via cognitive conflict of decimal numbers for the sixth graders. The purpose of the system is to gauge decimal concepts of students. When students entertain misconceptions or misleading ideas, the system will in accordance with the types of the wrong answer generate appropriate…

A key area of weakness in individuals with fetal alcohol spectrum disorder (FASD) is working memory, thus the goal of this study was to determine whether teaching children (aged 4-11) with FASD verbal rehearsal would increase their memory. Rehearsal training has been effective in other populations with working memory difficulties, so we…

This paper analyzes 12 recent within-study comparisons contrasting causal estimates from a randomized experiment with those from an observational study sharing the same treatment group. The aim is to test whether different causal estimates result when a counterfactual group is formed, either with or without random assignment, and when statistical…

Purpose: This study examined the effects of feedback training, familiarization training, and no training on naive listeners' word identification (WI) and magnitude estimation scaling (MES) judgments of the speech intelligibility of children with severe-to-profound hearing impairments. Method: Depending on the training group, listeners received a…

Background: School-based study recruitment efforts are both time consuming and challenging. This paper highlights the recruitment strategies employed by the national, multisite Trial of Activity for Adolescent Girls (TAAG), a study designed to measure the effectiveness of an intervention to reduce the decline of physical activity levels among…

Participants were trained and tested to select stimuli of differing physical quantities in the presence of 2 color contextual cues for more than and less than. Following more than and less than relational training, participants allocated the majority of their responses to the slot machine that shared formal properties of color with the contextual…

The Stop & Think Social Skills Program was implemented as a stand-alone primary prevention program using a sequential cohort design with two cohorts of kindergarten students. Cohorts were assessed at pretest and posttest using the Social Skills Rating System Teacher Questionnaire. Students in Cohort 1 showed improvement in Social Skills,…

The use of the Internet within educational settings means that the term "literacy" must be broadened to encompass new skills and reflect the merging of old and new literacy. For practitioners the challenge lies in making new media meaningful and empowering for students. Whilst interacting with hypertext has received much attention over the last…

Precision and generalizability for relative and absolute change scores were estimated by means of error/tolerance ratios and generalizability coefficients for 51 patients receiving 1 year of psychodynamic psychotherapy. These estimations involved 6 scale indicators and 3 raters. Practical suggestions are offered for the number of rates needed to…

A classroom of eighteen fourth and fifth graders in the Columbus, Ohio Public School system successfully evaluated how people obtain fossil fuels, how they are limited in nature, and how they can develop renewable energy solutions. Students modeled oil-drilling using: chocolate syrup, rice cereal, a baster, and a clear container. Chocolate oil…

This paper introduces a method for mining multiple-choice assessment data for similarity of the concepts represented by the multiple choice responses. The resulting similarity matrix can be used to visualize the distance between concepts in a lower-dimensional space. This gives an instructor a visualization of the relative difficulty of concepts…

Technology and mathematics. manipulatives have been brought together in a new format. This joining has resulted in virtual manipulatives that are available on the Internet for students. Virtual manipulatives have been defined as computer based renditions of common mathematics manipulatives and tools. Just as a physical object can be flipped,…

Using a quasi-experimental pretest/post test design, this study examined the effects of two summarization strategies on the reading comprehension and summary writing of fourth- and fifth- grade students in an urban, Title 1 school. The Strategies, "G"enerating "I"nteractions between "S"chemata and "T"ext (GIST) and Rule-based, were taught using…

Using data from a nationwide, large-scale experimental study of the effects of a connected classroom technology on student learning in algebra (Owens et al., 2004), this dissertation focuses on challenges that can arise in estimating treatment effects in educational field experiments when samples are highly heterogeneous in terms of various…

The purpose of this study was to examine the effects of four instructional methods--context clues, definition, elaboration technique, or word parts and word families--on the vocabulary growth and acquisition of adults enrolled in a community college developmental reading course. The study investigated whether performance in any or all of the four…
