Science educators in the United States are adapting to a new vision of how students learn science. Children are natural explorers and their observations and intuitions about the world around them are the foundation for science learning. Unfortunately, the way science has been taught in the United States has not always taken advantage of those…

In this chapter, eight foci relevant for science educators are presented and illustrated by paradigmatic examples and discussed in two parts. The first part "from science education to practice and authorities" discusses the four foci of: (1) developing concepts for instruction; (2) responding to the needs of schools; (3) connecting…

This essay describes Rasch analysis psychometric techniques and how such techniques can be used by life sciences education researchers to guide the development and use of surveys and tests. Specifically, Rasch techniques can be used to document and evaluate the measurement functioning of such instruments. Rasch techniques also allow researchers to…

Suggests a testing format suitable for thermodynamics, including questions and correct answers. Also offers a test question and an acceptable solution focusing on the elimination of certain steps in the glycolytic pathway. (SK)

Discusses issues related to examination questions which begin by asking students to "Describe an experiment to..." Indicates that this strategy is useful when focusing on important quantities/phenomena or "celebrated" experiments and that examining boards should not request students to describe experiments which verify or…

Students' justifications for the three-item formats provided were compared. The study confirmed the usefulness of justifications as a diagnostic tool and offered recommendations regarding the use of justifications, including their use in the construction of two-tier items. (Author/CW)

Aspects of practical assessment such as question design and management of the assessment are discussed. Reference is made to some of the problems and to the possibilities for innovation as a result of implementing practical assessment of the kind required by the General Certificate of Secondary Education examining groups. (CW)

Analyzes an old chemistry examination that was given to a college chemistry class in 1984. Contrasts several of the examination's features against most modern ones. Notes the emphasis on observable properties and the practical applications of substances. Argues that the newer examinations may stress too much theory and don't stress communication…

Promotes the use of machine-scored tests in basic engineering science classes. Discusses some principles and practices of machine-scored testing. Provides several example test items. Argues that such tests can be used to enhance basic understanding of concepts and problem solving skills. (TW)

The goal of this monograph is to explain the evaluation program designed by Schaumburg Community Consolidated District 54, Schaumberg, Illinois. It discusses the process used in the development of the model, the product, the implication for classroom teachers and the effects of using an evaluation to assess science process skills. The process…

Discusses some difficulties that medical students experience in taking exams containing multiple choice questions. Differentiates between multiple true/false type questions, in which several answers may be true, and one-out-of-four type, in which only one answer is correct. Provides tips for taking and making multiple choice tests. (TW)

After discussing task-specific information and form/content dissociation, presents evidence from training studies which suggests ways in which the form/content distinction might guide researchers in designing diagnostic measures leading to specific instructional strategies based on the diagnostics. (Author/JN)

Outlines a method to write multiple (four) versions of each examination. Reviews some advantages and disadvantages of multiple-choice and open-ended problems. Considers the writing and grading techniques used. Reports that the examination met the consistency requirement and received a good evaluation from students. (YP)
