A group of educators' stance on the implementation of South Africa's further education and training curriculum

In their dealings with educators in the Southern Cape region of South Africa, the researchers observed among them a degree of negativity and pessimism about the implementation of the Further Education and Training (FET) policy and curriculum during 2006. Exploratory discussions supported the surmise that a gap existed between policy formulation and the actual implementation of the policy in secondary schools. A qualitative research project confirmed this surmise, and served as the basis for a theoretical examination of the dynamics behind the stance adopted by the participants.

Support for EE From the National Science Education Standards and the Internet

Abstract

Two recent developments are likely to have a significant impact on the future of EE: (1) education reform initiatives based on the National Science Education Standards and (2) the development of promising Internet resources for teaching environmental sciences. This article urges the EE community to recognize that the time is ripe for environmental educators to embrace these developments. We examine several Internet-based resources that are used as tools for implementing standards-based reforms and promotion of EE's goals in K-12 classrooms.     

Evaluation of Teacher Perceptions and Potential of OpenOffice in a K–12 School District

Through this mixed-method evaluation study the authors investigated a pilot implementation of an open-source productivity suite for teachers in a K–12 public school district. The authors evaluated OpenOffice version 3.0 using measures identified by the technology acceptance model as predictors of acceptance and use of technology systems. During a four-week trial period, teachers rated the usefulness and usability of OpenOffice 3.0 and Microsoft Office. Results from quantitative measures and participant interviews revealed common perceptions of the software applications as well as common problems encountered by users. Based on these findings, implications and recommendations for larger scale implementations within a K–12 educational institution are discussed.     

Persistence and Motivation

Summary

This case study examines a new teacher's beliefs and perceptions about how and why technology can and should be used to support student learning. A middle school science teacher reflected upon her preparation for and applications of technology in her classroom. Data were generated through e-mail exchanges over the course of several months. Qualitative analysis identified themes including a nontechnology focus, expectations, rationale, impact, and beliefs and learned lessons. Findings suggest that for this teacher persistence was critical to learning in absence of pre-service or in-service learning opportunities in the effective application of technology to support learning. It is recommended that technology-oriented staff development incorporate theory, guidelines, models, and illustrations for effective and meaningful applications.     

Examining Student Digital Artifacts During a Year-Long Technology Integration Initiative

This study was situated within a year-long, statewide technology integration initiative designed to support technology integration within science, technology, engineering, and math classrooms. It examined the elements used in student artifacts in an attempt to investigate trends in digital artifact creation. Among several conclusions, this examination highlighted areas of significant improvement in student use of technology, such as an increase in the creation of PowerPoint presentations and the inclusion of multimedia elements. The study also highlighted areas for improvement, such as the low cognitive demand for content in the majority of the artifacts.
