In response to increasingly diverse student groups in U.S. schools, educational researchers have developed curricula that respond to students' unique needs, cultures, and experiences. Curricula that embrace a pedagogy of empowerment are known as Culturally Responsive Curricula (CRC), and such curricula specific to science are referred to as…

A simple electronic system for the measurement of high values of resistance is shown. This system allows the measurement of resistance in the range of a few megohm up to 10[superscript 9] [omega]. We have used this system for the evaluation of CdS thin film resistance, but other practical uses in the basic physics laboratory are presented.…

Creating slime fascinates students. Unfortunately, though intrigue is at its peak, the educational aspect of this activity is often minimal. This article describes a chemistry lab that closely relates to the slime lab and allows high school students to explore the concepts of chemical bonding, properties, and replacement reactions. It involves the…

Active and collaborative learning instruments were introduced into an introductory electrical and computer engineering course. These instruments were designed to assess specific learning objectives and program outcomes. Results show that students developed an understanding comparable to that of more advanced students assessed later in the…

Many science educators encourage student experiences of "authentic" science by means of student participation in science-related workplaces. Little research has been done, however, to investigate how "teaching" naturally occurs in such settings, where scientists or technicians normally do not have pedagogical training and generally do not have…

This article offers a case study of the evaluation of a redesigned and redeveloped laboratory-based cell biology course. The course was a compulsory element of the biology program, but the laboratory had become outdated and was inadequately equipped. With the support of a faculty-based teaching improvement project, the teaching team redesigned the…

Theory and practice are an odd couple. There is little doubt that theory deserves a place within today's primary classrooms. Pring (2004) suggests that theory is perceived as having come adrift from common sense. It is easy to see how, swept along in the daily pressures of the job, busy classroom teachers may question the relevance of seemingly…

Justice Department report finds that lack of training and experience in personnel may contribute to frequent unacceptable test results from forensic labs. (Author/MA)

A wide range of activities may be undertaken in elementary and secondary school science laboratories as part of regular curricular activities or optional classroom activities, including science fair projects. Among these is the culturing of microorganisms such as bacteria or fungi. There are various potential educational opportunities associated…

Described is a procedure for assessment of student performance in laboratory work (practical work) in Advanced Level Biology in England. Some historical background is included. (PB)

Describes the development of new laboratory-based assessments to promote the professional development of technicians in education. Discusses defining standards, the new Scottish/National Vocational Qualifications, and awarding Arrangements. (JRH)

Data from this study suggest that evaluations of long-term accumulations of students' laboratory analyses should be standard procedure to detect deviations from the accepted true assays. Efforts are recommended to determine the cause of the error and the implications or grading procedures reconsidered. (Author/MA)

This paper presents the procedures, results and conclusions of a study designed to determine whether three different methodological approaches to the laboratory for a general education physical science course would lead to the same behavioral outcomes. Students enrolled in the physical science course were randomized into one of three laboratory…

Describes the investigative learning method for use in college-level biology courses. Discusses the graduate teaching assistants' roles and the strategies they need to examine such as teaching and assessment. Uses qualitative and quantitative approaches for the evaluation of the program. (Contains 16 references.) (YDS)

An observational instrument called the Laboratory Interaction Categories-Student (LIC) is described. The LIC is an easily understandable and usable tool for assessing pupil laboratory performance. (MP)
