Laboratory studies on a range of animals have identified a bias that seems to violate basic principles of rational behavior: A preference is shown for feeding options that previously provided food when reserves were low, even though another option had been found to give the same reward with less delay. The bias presents a challenge to normative…

In case of pregnancies, one of the most common pathological conditions in internal medicine is aneamia with iron-deficiency. Furthermore, iron deficiency may also affect the mother and the fetus negatively. We wanted to find out which group of expectant mothers are mostly affected, which factors influence the development of aneamia. It was also…

Although shyness has often been found to be negatively related to vocabulary, few studies have examined the processes that produce or modify this relation. The present study examined executive functioning skills and home environmental stimulation as potential mediating and moderating mechanisms. A sample of 3 1/2-year-old children (N = 254) was…

This article discusses why the study of earthworms has fascinated many scientists, and why earthworms make ideal experimental animals for students to test in the laboratory. Although earthworms may appear to be primitive, they are governed by both circadian and seasonal rhythms, just as more advanced organisms are. They possess an intelligence…

Discusses the preparation of a solution of assigned molarity as a suitable test of laboratory technique for nonscience majors. (MLH)

Medical laboratory science professionals are healthcare practitioners who provide laboratory data that aids in the diagnosis, treatment, and prevention of disease. However, there is a large shortage of these professionals who perform the laboratory tests behind the scenes with very minimal patient contact. The purpose of this research was to…

The authors provide a brief review of the history and assessment of math anxiety, its relationship to personal and educational consequences, and its important impact on measures of performance. Overall, math anxiety causes an "affective drop," a decline in performance when math is performed under timed, high-stakes conditions, both in laboratory…

The preponderance of the evidence from the engineering education literature demonstrates that inductive teaching methods are more effective than deductive approaches. When students are already familiar with the fundamentals of a topic, however, deductive approaches may make more sense. This paper discusses the implementation of a combination of…

This research study is an investigation of student-laboratory (i.e., lab) learning based on students' perceptions of experiences using questionnaire data and evidence of their science-laboratory performance based on paper-and-pencil assessments using Maryland-mandated criteria, Montgomery County Public Schools (MCPS) criteria, and published…

Laboratory tests used to determine status and to evaluate and/or maintain process control of the various sludge treatment processes are introduced in this lesson. Neither detailed test procedures nor explanations of how the tests should be applied to every unit are explained; this information is provided in other modules. The instructor's manual…

Studied the effects of answer review on results of a computerized adaptive test, the laboratory professional examination of the American Society of Clinical Pathologists. Results from 29,293 candidates show that candidates who changed answers were more likely to improve their scores. (SLD)
