A novel educational chart that represents the acid--base behavior of 100 s-, p-, d-, and f-element oxides depending on the element's electronegativity and oxidation state was designed. An updated periodic table of said oxides was developed. A mathematical criterion based on the chart was derived which allows prediction of the behavior of…

Renal transport is a central mechanism underlying electrolyte homeostasis, acid base balance and other essential functions of the kidneys in human physiology. Thus, knowledge of the anatomy and physiology of the nephron is essential for the understanding of kidney function in health and disease. However, students find this content difficult to…

When organic chemistry students encounter competing reactions, they are often overwhelmed by the task of evaluating multiple factors that affect the outcome of a reaction. The use of a decision tree is a useful tool to teach students to evaluate a complex situation and propose a likely outcome. Specifically, a decision tree can help students…

Drama and imagination have a place in every classroom, not just in the English teacher's. In fact, nowhere are they more critical to students' motivation than in bringing to life the often arcane equations of science. By inventing curiosity-provoking scenarios that require students to apply science concepts and processes as integral and…

Many college science educators have moved away from the traditional lecture format and toward learner-centered classroom environments. Yet many of us struggle to cover large content loads, reverting at times to rote memorization. This paper suggests rote memorization simply does not work and students must be actively engaged to learn. (Contains 1…

Sometimes it is difficult to decide whether a student has a true understanding of a physics concept or whether they are very good at rote learning key words and phrases. Sometimes, when you are marking exams, you feel you have to give the student full marks because everything is there, even though it is not quite "right". This is where a diagram…

Reports observations of primary teachers (n=14) efforts to provide activity-based lessons for their pupils. Teachers' beliefs that their lessons were student-centered were not confirmed by the observations of the lessons. Discusses implications of the findings for inservice teacher education and parental involvement. (MDH)

Japan produces more technicians and engineers than the U.S. as a result of higher standards for high school graduation and college entrance, highly effective teacher inservice training, and public support for science and technology. However, the reliance on imitation and rote learning remains a weakness in the Japanese educational system. (WD)

American officials lament U.S. students' mediocre skills in math and science, and warn that China, with its firm academic emphasis on those subjects and its enormous student population, stands to reap economic rewards from American complacency. They suggest reforming math and science education in the U.S. to more closely resemble the systems…
