Nature of science (NOS) is now a well-established focus of science education and a key element in defining scientific literacy. In recent years, a particular specification of NOS, often described as "the consensus view," has become very influential and has gained ready acceptance in many countries around the world as a template for…

The "consensus view" on the nature of science (NOS) is now outmoded. To help frame an enduring alternative, one should attend first to the "why" of NOS education. Functional, or civic, scientific literacy is foundational. Acknowledging a need for consumers and citizens to assess the reliability of scientific claims in personal…

The term "validity" is one of the most important and one of the most debated concepts in educational measurement. In this paper, I argue that various different approaches can all be viewed from an associational perspective. I also argue that our understanding will be enhanced by adopting some basic ideas of scientific reasoning to the…

This column focuses on promoting learning through assessment. Formative assessment probes are designed to uncover students' ideas about objects, events, and processes in the natural world. This assessment information is then used throughout instruction to move students toward an understanding of the scientific ideas behind the probes. During the…

How can assessments measure complex science learning? Although traditional, multiple-choice items can effectively measure declarative knowledge such as scientific facts or definitions, they are considered less well suited for providing evidence of science inquiry practices such as making observations or designing and conducting investigations.…

At a time when scientific and technological competence is vital to the nation's future, the weak performance of U.S. students in science reflects the uneven quality of current science education. Although young children come to school with innate curiosity and intuitive ideas about the world around them, science classes rarely tap this potential.…

Practitioners in informal science settings--museums, after-school programs, science and technology centers, media enterprises, libraries, aquariums, zoos, and botanical gardens--are interested in finding out what learning looks like, how to measure it, and what they can do to ensure that people of all ages, from different backgrounds and cultures,…

The National Assessment of Educational Progress (NAEP) and its reports are a key measure in informing the nation on how well the goal of scientific literacy for all students is being met. The "Science Framework for the 2011 National Assessment of Educational Progress" sets forth the design of the NAEP Science Assessment. The 2011 NAEP…

This document sets forth recommendations for the design of a new science assessment. The assessment resulting from this framework will start a new NAEP science trend (i.e., measure of student progress in science) beginning in 2009. This framework represents a unique opportunity to build on previous NAEP science work as well as key developments in…

Traces how the idea of measuring the connection between school science and public awareness of science has emerged. Describes the Program for International Student Achievement (PISA) project's indicators of educational progress in science. Contains 28 references. (Author/WRM)

Theme-based tests provide an assessment tool that instructs as well as provides a single general context for a broad set of biochemical concepts. A single story line connects the questions on the tests and models applications of scientific principles and biochemical knowledge in an extended scenario. Theme-based tests are based on a set of…

While the 1960s and 1970s came to be known as the era of curriculum development in science, it appears that the 1980s and the 1990s will be known as the time of curriculum development with strengthened attention to implementation and evaluation. This book examines the assessment of elementary school science and provides numerous examples of…

This document presents the framework and rationale for assessing the science achievement of students throughout the United States in 1996 and 2000. A general overview of the National Assessment of Educational Progress (NAEP) and the NAEP Science Framework adopted by the National Assessment Governing Board (NAGB) is provided. The process by which…

This study reports research findings on assessment of the science classroom learning environment and its association with two student outcomes--attitudes toward science and national examination scores. Modified versions of the WIHIC and TOSRA questionnaires in the Indonesian language were administered to 1400 students and their teachers. This…

Scientific literacy and authenticity have gained a lot of attention in the past few decades worldwide. The goal of the study was to develop various authentic assessments to investigate students' scientific literacy for corresponding to the new curriculum reform of Taiwan in 1997. In the process, whether ninth graders were able to apply school…
