A simple experiment was developed to introduce students to the sustainable procurement of water through fog harvesting that can be used for drinking or irrigation purposes. Access to clean water and sanitation is problematic particularly within dry regions such as in areas of Peru, although there is a significant amount of fog in the mountainous…

One challenge associated with introducing systems thinking in chemistry classrooms is the increase in content complexity that students face when they engage in this type of approach. Placing core chemical ideas within larger systems has promise, as long as students are not overwhelmed by the added complexity. Although there are many potential…

Now that most states have adopted the new Common Core State Standards, the next major challenge is to simplify and implement them by 2014. That is why it is important to begin this work now. Joe Crawford, Milken Award-winning educator and author of "Using Power Standards to Build an Aligned Curriculum", shares his proven process for…

Examines the developmental needs for Web-based courses, focusing on content, user interface, and pedagogy. Studies the Web course development process as a system, explores various stages in the process, and includes graphs and tables designed to be used as management tools for the effective development of Web-based courses.

Discusses three phases of instructional design (ID)--definition of instructional parameters, analysis and synthesis of instructional alternatives, and implementation of instructional plan--and presents a 15-step ID model. Included for each step are a descriptive name, boxed example, and rationale and (as applicable) current state of technology for…

This article discusses tools developed to aid the systems analysis process (program evaluation and review technique, Gantt charts, organizational charts, decision tables, flowcharts, hierarchy plus input-process-output). Similarities and differences among techniques, library applications of analysis, structured systems analysis, and the data flow…

The development of a unified information handling program to meet the needs of the rapidly growing environmental health staff of the Research and Environmental Health Division of the Medical Department of Exxon Corporation was achieved by using systems analysis techniques to evaluate both information needs and existing information services. The…

A broad range of well-structured problems--embracing forms of diagnosis, catalog selection, and skeletal planning--are solved in expert computer systems by the method of heuristic classification. These programs have a characteristic inference structure that systematically relates data to a pre-enumerated set of solutions by abstraction, heuristic…

This volume, the fourth of a five-volume series, contains three onsite case studies of organization development (OD) selected from a sample of 76 school districts. The purpose of the case studies was to analyze in detail different types of OD programs and their use. Each case study represents a different OD focus: case study A involves a survey…
