The German national educational standards state explicitly that students should be enabled to successfully interact with dynamic geometry software. In a feasibility study on providing a standardized assessment instrument by digital means, in order to assess students' mathematical competencies, the implementation of a task with such a dynamic…

Educational technology is evolving and growing at a faster pace than ever before. Such fast-paced growth makes it difficult to evaluate and measure its effectiveness in a timely manner and creates a need for independent academic literature in this area. This study serves to address to this need and contribute to the body of literature. The intent…

Many of today's adolescents are constantly engaging with information through texting, watching videos, listening to music, and even writing papers. Learning to interact properly with information through writing presents a challenge for the students because they are employing all of these applications at once and believe that they are multitasking…

In this article, we present analyses from a researcher-practitioner partnership in the District of Columbia Public Schools, where we are exploring the impact of educational software on students' academic achievement. We analyze a unique data set that combines student-level information from the district with data of student usage of a mathematics…

The purpose of this study was to assess if there was a relationship between sixth, seventh, and eighth grade student's level of mastery of basic math facts and their mathematical scaled score from a standardized test, whether computer assisted instruction (CAI) software improved seventh grade students' ability to master their basic math…

We conducted an evaluation study of the Middle School Algebra Readiness Initiative, a middle school mathematics intervention that was implemented in two West Virginia school districts during the 2011-2012 school year. In participating middle schools, the Carnegie Learning MATHia® software intervention and accompanying classroom curriculum were…

This study examined the relationship between STAR Math gains and TCAP composite scores. The purpose of this study was to determine if there was a significant relationship between STAR Math pretest and posttest gains over the course of the 2005-2006 academic year through the use of the STAR Math software program and TCAP math composite scores at…

This paper extends the theory of conditional covariances to polytomous items. It has been proven that under some mild conditions, commonly assumed in the analysis of response data, the conditional covariance of two items, dichotomously or polytomously scored, given an appropriately chosen composite is positive if, and only if, the two items…
