Introduces the All The News critique project in which students use the Internet to critique the information they view and develop an understanding of why some information may not be credible, scientifically valid, or methodologically sound. Includes a sample project with learning outcomes, assessment criteria, and related science standards. (KHR)

Details a project in which successful DNA analysis techniques were developed by students and their teacher in a rural school. Focuses on a study of sage grouse. (DDR)

Suggests the use of Internet-based inquiry lessons to explore water quality. Acknowledges that inquiry occurs along a continuum ranging from open to structured. Uses river water quality data from the website, Water on the Web. (DDR)

Explores the interaction and sequencing of hands-on activities, writing, and reading in the science classroom viewed from a constructivist perspective. Describes the Hands-On, Writing and Reading for Understanding approach designed to accommodate various learning styles and to challenge and direct student learning. Discusses sequencing of…

Examines the processes of science focusing on the higher-order skills and the role that relevance may play in their acquisition. Argues that an open inquiry style of instruction appears best suited to stimulating the learning of process skills because it allows students to pursue problems of genuine relevance. Contains 26 references. (JRH)

Describes a Star Party which involves comparing the different colors of the stars, demonstrating how astronomers measure the sky with degrees, determining the cardinal direction, discussing numerous stories that ancient civilizations gave to constellations, exercising science process skills, and using science instruments. (JRH)

Describes an investigation of the associations between students' perceptions of laboratory environment and their attitudinal, cognitive, and practical performance outcomes. Assesses student outcomes in three distinct areas: (1) student attitudes; (2) achievement on a written examination; and (3) practical performance, specifically in the biology…

Explores the reasons why data logging is still not an integral part of the science curriculum in the majority of British schools. Suggests some strategies to assist science teachers in taking the initial steps towards utilizing this technology. (DDR)
