Understanding complex systems is fundamental to understanding science. The complexity of science systems makes them very difficult to understand because they are composed of large number of variables with dynamic interdependencies that determines the behavior of the systems. Hence, understanding complex system requires students to build an…

Resilience is an area of research that has important implications for the educational improvement of English Language Learners (ELLs) because it focuses on ELLs who are successful in school despite the presence of adverse conditions such as living in economically- and socially-disadvantaged circumstances. This study compared the classroom and…

Everyone acknowledges the importance of leadership in good schools, but sometimes a leader's influence extends into unexpected areas. Getting admitted to and succeeding in college is certainly the result of hard work on the part of individual students and their families, but for many kids, particularly those from impoverished backgrounds or from…

Recently, the significant role that pronunciation and prosody plays in processing spoken language has been widely recognized and a variety of teaching methodologies of pronunciation/prosody has been implemented in teaching foreign languages. Thus, an analysis of how similarly or differently native and L2 learners of a language use…

In this technical report, we present the results of a reliability study of the seventh-grade multiple choice reading comprehension measures available on the easyCBM learning system conducted in the spring of 2011. Analyses include split-half reliability, alternate form reliability, person and item reliability as derived from Rasch analysis,…

Since the mid-1990s, the link between recasts and L2 development has been extensively tested, and the results from those studies have largely demonstrated that recasts have a positive effect on L2 learning. With this firm support from previous empirical evidence, studies have begun to focus on how recasts assist learning and under what conditions…

Our study focuses on the correlation of concept map (CMap) structures and learning success tested with short answer tests, taking into particular account the complexity of the subject matter. Novice sixth grade students created CMaps about two subject matters of varying difficulty. The correlation of the complexity of CMaps with the post-test was…

Extensive reading (ER) has become a common feature of many English as a second or foreign language (ESL/EFL) programs. There is evidence that reading large amounts of easy, interesting material may improve foreign language skills, most notably in vocabulary, reading rates, and overall proficiency. However, teacher evaluation of extensive reading…

Purpose: The purpose of this study was to identify the most appropriate item response theory (IRT) measurement model for aphasia tests requiring 2-choice responses and to determine whether small samples are adequate for estimating such models. Method: Pyramids and Palm Trees (Howard & Patterson, 1992) test data that had been collected from…

This article reports a quasi-experimental study on the effects of multimedia teaching and learning in English Literature--a subject which places high cognitive load on students. A large-scale study was conducted in 4 high-achieving secondary schools to examine the differences made to students' learning and performance by the use of multimedia and…

Any meaningful initiative to improve the teaching and learning in introductory control systems courses needs a clear test of student conceptual understanding to determine the effectiveness of proposed methods and activities. The authors propose a control systems concept inventory. Development of the inventory was collaborative and iterative. The…

Reliability and validity are integral concepts in assessment design. Test speededness, the influence of time constraints on test taker performance, is often an overlooked threat to reliability and validity, especially in classroom-based testing. The purpose of this study is to evaluate the degree of test speededness of classroom-based assessments…

Publishing graded readers is big business, but there is evidence that the texts themselves are not being read in sufficient quantity to improve language proficiency. This article reports on a study of graded readers, focusing on interviews with some major publishers of graded readers, to investigate their production rationales. The findings…

This study explores the development of multiple dimensions of linguistic complexity in the writing of beginning learners of German both as a group and as individuals. The data come from an annotated, longitudinal learner corpus. The development of lexicogrammatical complexity is explored at 2 intersections: (a) between cross-sectional trendlines…

Boys need books with which they can connect, books that reach out to them with characters that reflect themselves, books that feature people who speak and look and act like the people in their lives. Among the functions of literature in children's lives, two are particularly relevant: facilitating literacy skills and providing role models. The…
