This paper describes HASbot, an automated text scoring and real-time feedback system designed to support student revision of scientific arguments. Students submit open-ended text responses to explain how their data support claims and how the limitations of their data affect the uncertainty of their explanations. HASbot automatically scores these…

A conception of social testing is described in which students are directed to give themselves grades at two moments: first, after filling in answers that they recall alone; second, after asking others in the class for mediating help during social interaction. The first grade is an estimate of individual efforts, without social connections. The…

The implementation of interactive courseware within a task-based learning (TBL) approach was conducted for English Writing for Business to Chinese students in an applied foreign languages department housed in a university of technology. The development of the interactive courseware is based on Mayer's multimedia learning theory, which allows…

"Getting Prepared 2018" examines Minnesota public high school graduates from the classes of 2009-2017 who enrolled in postsecondary education and those enrolled in developmental education. This report provides insight into the academic readiness of Minnesota public high school graduates. Developmental education adds to the overall cost…

In 2014, a new General Education Development (GED) assessment will be implemented. The new, more rigorous test will be aligned with the Common Core State Standards (CCSS) and will use a new test delivery model-computer-based testing (CBT) to replace the paper-and-pencil examination. These two changes have important implications for correctional…

Many methods exist for imputing missing data but fewer methods have been proposed to test the missing data mechanism. Little (1988) introduced a multivariate chi-square test for the missing completely at random data mechanism (MCAR) that compares observed means for each pattern with expectation-maximization (EM) estimated means. As an alternative,…

This issue of ETS Policy Notes (Vol 21, No. 2) highlights the discussion from "Taking Action: Navigating the Common Core State Standards and Assessments," a conference co-convened by ETS and the National Urban League (NUL) in February 2013.

This article systematically examines differences between student and faculty perspectives on quality instruction, using local data for a regional university's college of business matched to RateMyProfessors.com evaluations. Particular attention is focused on gender bias, "hotness," and "easiness." In addition to documenting a…

Prismatic refraction is a classic topic in science education. To investigate how undergraduate students think about prismatic dispersion, and to see how they change their thinking when observing dispersed images, five teaching experiments were done and analysed according to the Model of Educational Reconstruction. For projection through a prism,…

One major threat to validity in high-stakes testing is construct-irrelevant variance. In this study we explored whether the transition from a paper-and-pencil to a computer-based test mode in a high-stakes test in China, the College English Test, has brought about variance irrelevant to the construct being assessed in this test. Analyses of the…

According to Question-Under-Discussion (QUD) models of discourse interpretation, clauses cohere with the preceding context by virtue of providing answers to (usually implicit) questions that are situated within a speaker's goal-driven strategy of inquiry. In this article we present four experiments that examine the predictions of a QUD model of…

This study provides a new conceptualization of educational leadership with a multilevel and integrative approach. It examines the impact of multilevel leadership (MLL) on the effectiveness of technical educational institutes through the mediating effects of organizational communication, bases of power and organizational culture. Data were…

This study is a fraction of a larger research on cheating, at the School of Engineering (SOE). The study design used a descriptive survey approach and a document analysis. A designed confidential self-report questioner was used as the main instrument, for this study, with the sample size of 100 subjects and response rate of 95%. The tool was…

This study aims to explore the users' behaviour and acceptance of social media for learning in higher educational institutions with the help of the extended Technology Acceptance Model (TAM). TAM has been extended to investigate how ethical and security awareness of users affect the actual usage of social learning applications. For this purpose, a…

This study examined how student perceptions of math/statistics instructors' argumentativeness and verbal aggressiveness are related to student perceptions of classroom communication climate, student state motivation, and student math anxiety. A total of 216 completed questionnaires were returned by the student participants (96 males and 120…
