Compression of parallel texts

The world-wide use of digital storage and communications devices is increasing the need to make texts available in multiple languages. In this article we explore the possibility of storing a compressed form of a translated version of a text, taking advantage of the availability of the original text. The original text provides some of the semantic content of the text that is to be compressed, and therefore makes it possible for compression to be more efficient than if that information were not available. We begin with an experiment to evaluate the information content of a text when a parallel translation is available. This is achieved by having human subjects guess texts letter by letter, with and without a parallel translation. The perceived information content of a text can be determined from the way subjects make their guesses. The design and results of this experiment are described. The main conclusion is that while the text is considerably more predictable with the aid of a parallel translation, there is a surprising amount of information introduced by the translation. Insights obtained from this experiment are then applied in the design of a mechanical system for compressing parallel texts. The system stores one translation of a text intact, and then compresses further translations of the text with the aid of the original. The method described is able to compress texts significantly better than is possible without the aid of a parallel text. Aspects of the design are also applicable to future compressors that might take advantage of the semantic content of a text to obtain better compression.     

Using argumentation as a learning strategy to improve student performance in engineering Statics

ABSTRACT

Research suggests that a significant reason that a large number of students earn low grades in the fundamental engineering science course Statics is that they may be entering the course with incorrect conceptual knowledge of mathematics and physics. The self-explanation learning approach called collective argumentation helps k-12 students to understand their misconceptions of mathematical principles that often appear abstract to them. This study investigated collective argumentation as an instructional approach that helps engineering students identify and correct their misconceptions of topics taught in Statics. Results suggest that argumentation improves student performance as measured by grades earned on semester exams. Survey and focus group results suggest that students did not understand the argumentation process. Therefore, the students did not like using it as a learning approach.     

Using Early Learning Standards to Provide High-Quality Education for All Children: The Early Learning Guidelines Toolkit

Today with the rise in the number of 3- to 6-year-old children enrolled in center-based early childhood programs, and a focus on program quality, it becomes imperative for educators to have a better understanding of the role research plays in establishing high-quality programs as these programs provide much of the foundation that supports early learning and development (Child Trends, 2014). Although psychology, and the role of child development research in particular, has always been integral to the field of early childhood education beginning with the seminal works of Piaget, Bronfenbrenner, Bruner, and others (Lickona,1971), the field had never fully embraced the use of research to inform practice, until the 1990s. This had been, in part, because the field of early childhood education originally viewed itself as a field of practitioners that provided for the everyday care and needs of young children, whereas it viewed child development researchers as scientists who paid little attention to the practical needs of classroom teaching (Takanishi, 1981 Takanishi, R. (1981). Early childhood education and research: The changing relationship. Theory into Practice, 20, 86–92.[Taylor & Francis Online] , [Google Scholar]). Although, today, there is no longer this ideological divide between the two areas, with the child development research being used to inform educational practice and policy (Center for the Developing Child, 2007), nevertheless there still remains a gap in the ability of educators to effectively implement evidence-based practices. Given the increased focus on providing young children with access to high-quality education, and the need for teachers to implement evidence-based practices the present paper attempts to bridge the gap by providing a brief overview of the science of early childhood development, its importance for development of early learning standards, and an overview of the Early Learning Toolkit which was developed to provide early learning educators guidance and resources to support the implementation of early learning standards within their own states as well as well across the nation. The goal of this article is to bridge theory and practice in early childhood education.     

The becoming place: A study of educational change in a small college

One of the more astonishing characteristics of educational research is the relative lack of social organizational analyses of higher educational institutions. There is even a greater gap in the literature with regard to thechange process associated with a given university or college. The present study is an examination of one college's attempt to change from a traditional white female finishing college to a larger biracial and coeducational college committed to experimental and innovative educational programs. Two ideal types of educational social organizations are utilized as explicit aids for the specification of the educational change process observed for the Becoming Place during the time period 1969 to 1975. The major findings, which are based on several data sources, can be summarized as follows. (1) Even when a proposed educational change is characterized by ideals of maximum involvement in the decision making process for all members of a college community, resistance to the change can be very substantial. (2) Ironically, little or no involvement by the faculty, students, and alumni in the initial decision to innovate was a major factor for the resistance to educational social change. The research is concluded with a consideration of the findings in terms of possible implications for the future of small colleges.An earlier version of this paper was presented at the annual meeting of the Southern Sociological Society, Knoxville, TN, April 1980.     

Using student norms to create positive learning environments

Ever since brash young students goaded one another to race chariots through the streets of the ancient world, elders have tried to understand and harness the energy of late adolescent normative group behavior. John Braxton and Timothy Caboni introduce a perspective and survey instrument that may help today's educators do just that.     

Online or Face-to-Face: Do Mission-Related Student Learning Outcomes Differ?

This study investigated how an authentic assessment program was used to examine student learning outcomes within the context of a Christian university’s institutional mission, core values, and distinctive qualities. For the purposes of this study, an authentic assessment program is defined as assessing student-produced work within the context of the institutional mission. A sample of 1,814 undergraduate students taking one or more general education courses at the university during the 2007–2009 academic years was examined for any significant differences in student learning outcomes. A univariate analysis of covariance (ANCOVA) indicated the Student Assessment System (SAS) scores for the online students were not significantly different from the SAS scores for the face-to-face (F2F) students after controlling for course grade. These results suggest that online students achieved the same critical mission-related educational outcomes that the university required of its F2F students. An implication of this finding is that the university just as effectively articulated its faith-based mission and vision to the online students as it did to its students taking classes F2F.     

Concurrent and Longitudinal Contributions of a Brief Assessment of Reading‐Specific Executive Function to Reading Comprehension in First and Second Grade Students

Executive function (EF) contributes significantly to reading comprehension across the lifespan. Emerging research indicates domain‐specific assessments of EF are better suited for assessment and intervention in academic contexts. For example, graphophonological‐semantic cognitive flexibility (GSF), the ability to flexibly switch between the graphophonological and semantic components of printed words, contributes uniquely to reading comprehension across the lifespan, and GSF training improves children's reading comprehension. This study compared the original GSF measure, which is problematic for use in schools due to its subjectively interpreted explicit explanation component, to an abbreviated implicit task that is better suited for assessment of GSF in practical contexts in 68 first and second grade students. Implicit and explicit GSF contributed uniquely to reading comprehension concurrently and longitudinally when children (n = 31) were in third and fourth grades, beyond verbal ability, decoding ability, and matrix reasoning.
