Parts Of The Whole: Observing The State Of The System, Dorothy Wallace Dec 2009

Parts Of The Whole: Observing The State Of The System, Dorothy Wallace

Numeracy

This column draws on the approach of statistician J. Edwards Deming to analyze sources and consequences of variation in an education system. Educational systems are not immune from the effects of poor statistical control, which makes it difficult for teachers to teach effectively and for managers such as principals to improve on school performance. It is also argued that the need for statistical control in these areas is in tension, if not outright conflict, with our goals for educating students.

Numeracy: Open-Access Publishing To Reduce The Cost Of Scholarly Journals, Todd A. Chavez

Numeracy

Each fiscal year, as academic librarians throughout the United States prepare materials budgets, a national “groan” ensues. Regardless of their format (i.e. print or digital), serial subscription costs are escalating, in the process impacting the role of the library in advancing scholarly communication . This paper examines some of the economic issues concerning open-access (OA) journal publishing. The importance of quantitative literacy is suggested for librarians and academics seeking a better understanding of alternatives to traditional journal subscription models and to anyone considering ventures into OA publishing. Quantitative literacy is essential for managing alternatives to the rising cost of scholarly ...

Are Statistics Labs Worth The Effort?--Comparison Of Introductory Statistics Courses Using Different Teaching Methods, Jose H. Guardiola, Nadina Duran-Hutchings, Hassan Elsalloukh

Numeracy

This paper compares the academic performance of students in three similar elementary statistics courses taught by the same instructor, but with the lab component differing among the three. One course is traditionally taught without a lab component; the second with a lab component using scenarios and an extensive use of technology, but without explicit coordination between lab and lecture; and the third using a lab component with an extensive use of technology that carefully coordinates the lab with the lecture. Extensive use of technology means, in this context, using Minitab software in the lab section, doing homework and quizzes using ...

Science For The English Language Learner: Strategies To Enhance Comprehension, Allen Rauch, Vicky Giouroukakis Ph.D.

Faculty Works: Education

According to the New York State Science Learning Standards, all students, including ELLs, need to “understand and apply scientific concepts, principles, and theories...” (NYS Learning Standards for Math, Science, Technology, 1996, p.1). [They] are expected to acquire skills such as discussing, analyzing, reading, and writing in ways similar to those of a practicing scientist” (Medina-Jerez, Clark, Medina, & Ramirez-Marin, 2007, Science for ELL, para. 2). Most students in science, however, have difficulty comprehending science content (Schoenbach et. al., 1999) and are challenged by the specialized terminology in science. Furthermore, students believe that science is a body of knowledge rather than ...

Deliberation Versus Dispute: The Impact Of Argumentative Discourse Goals On Learning And Reasoning In The Science Classroom, Mark Felton, Merce Garcia-Mila, Sandra Gilabert Dec 2009

Deliberation Versus Dispute: The Impact Of Argumentative Discourse Goals On Learning And Reasoning In The Science Classroom, Mark Felton, Merce Garcia-Mila, Sandra Gilabert

Faculty Publications

Researchers in science education have converged on the view that argumentation can be an effective intervention for promoting knowledge construction in science classrooms.However, the impact of such interventions may be mediated by individuals’ task goals while arguing. In argumentative discourse, one can distinguish two overlapping but distinct kinds of activity: dispute and deliberation. In dispute the goal is to defend a conclusion by undermining alternatives, whereas in deliberation the goal is to arrive at a conclusion by contrasting alternatives. In this study, we examine the impact of these discourse goals on both content learning and argument quality in science.

Semi-structured interviews were used to explore the beliefs about teaching, learning, and the Nature of Science. Four cohorts of teachers represented the ...


Differentiated Instruction In The New York State Geometry Curriculum, Vicki S. Newman Dec 2009

Differentiated Instruction In The New York State Geometry Curriculum, Vicki S. Newman

Education and Human Development Master's Theses

In today’s heterogeneous classrooms, studies show success on a social level but on an academic level, the needs of individual learners are not necessarily being met. Typical teaching models in mathematics, lecture and student practice, teach to “the middle,” to a given class average learner, without necessarily giving attention to the struggling special needs student or to the oft times bored, gifted student. Understanding by Design is a curriculum model that focuses on teaching for understanding. It incorporates performance standards as well as essential questions and understandings. It requires the instructor to determine goals, plan lessons, and choose textbook ...

Teaching Science In Light Of World View: The Effect Of Contextualized Instruction On The Scientific Compatibility Of Religious College Students' World Views, Paula Rae Gossard

Dissertations

Authors of recent science reform documents promote the goal of scientific literacy for all Americans (American Association for the Advancement of Science, 1989, 1993). Some students, however, feel apprehensive about learning science due to perceptions that science is antagonistic to their world views (Alters, 2005; Esbenshade, 1993). This study investigated the effect of an introductory science course taught in the context of a Christian, theistic world view on the scientific compatibility of religious college students' world views. For the purposes of this study, students' understanding of the nature of science, affective attitudes toward science, and beliefs regarding creation were used ...
