The aim of this research is to advance in the teaching-learning process of representing quadratic functions, both with pencil and paper and with a technological tool. For this purpose, a didactic experience is presented. Firstly, it is explained in the traditional way how to graph a quadratic function; secondly, students are introduced to the…

How can the key concept of equivalent expressions be addressed so that students strengthen their representational fluency with symbols, graphs, and numbers? How can research inform the synergistic use of both paper-and-pencil analysis and computer algebra systems (CAS) in a classroom learning environment? These and other related questions have…

We develop an Easy Java Simulation (EJS) model for students to experience the physics of idealized one-dimensional collision carts. The physics model is described and simulated by both continuous dynamics and discrete transition during collision. In designing the simulations, we discuss briefly three pedagogical considerations namely (1) a…

This article presents a designed learning environment intended to engage students in learning about the relationships among multiple representations as they work together on a shared task. Over the course of several extended problem-solving sessions, groups developed several successive alignments of participants and representations as they learned…

The 2017 edition of the "Digest of Education Statistics" is the 53rd in a series of publications initiated in 1962. The "Digest" has been issued annually except for combined editions for the years 1977-78, 1983-84, and 1985-86. Its primary purpose is to provide a compilation of statistical information covering the broad field…

Examines the issue of technology in education as the vehicle whereby an educational-industrial complex is evolving. Presents background information on the introduction of technology in education; technology suppliers and the education market; the educational-industrial complex (hardware, software, services, and private education companies);…

Presents in tabular form a summary of publishing requirements, guidelines, and suggestions from 59 current educational communications, technology, and library science journals and magazines to serve as a reference to potential contributors. (Three references) (LRW)

This study at the State University of West Georgia examined barriers and influences to faculty adoption of technology into instruction. The sample for the study was the 348 full-time faculty at the university. A survey was designed to determine the faculty's self-reported knowledge and use of technology, factors influencing their use of…

This study examined the technology-related perceptions, habits, and training/professional development experiences of first- and second-year teachers. The goal was to provide objective, research-based information on the preparedness of "new" teachers (as compared to "experienced" teachers) to implement various forms of…

This report presents the results of a study of how emerging technologies can help educators deliver standards-based education to K-12 students. The first section of the report provides background on the new technology offerings and defines smart desktop systems. The second section lists critical questions for decisionmakers related to general…

Since 1994, the National Center for Education Statistics (NCES) has surveyed public schools to measure what proportion of them is connected to the Internet. In the fall of each academic year, a new nationally representative sample of approximately 1,000 public schools has been surveyed about Internet access and, since 1996, about the types of…

Advances in information technology, coupled with changes in society, are creating new paradigms for education. The Web, as a medium of learning and instruction, has the potential to support the creation of well-designed resources. A table of features and components associated with Web-based instruction learning environments is provided.…

In response to national concern over declining standards in students' writing abilities, an increasing number of schools have adopted the use of word processors in an effort to increase literacy skills. The instructional effectiveness of word processors in 20 second-grade students was analyzed and it was found that computers facilitate improvement…

In fall 1995, the National Center for Education Statistics (NCES) conducted a survey of advanced telecommunications in private schools to provide baseline data on computer and Internet availability, and allow for comparisons with public schools. To revisit the issue of computer and Internet availability in private schools and measure changes since…

Since 1994, the National Center for Education Statistics (NCES) has surveyed nationally representative samples of approximately 1,000 public schools in the fall of each academic year on Internet access and, since 1996, on the types of Internet connections used. The most recent survey of Internet access indicates that public schools in the United…
