A molecular approach for introducing entropy in undergraduate physical chemistry course and incorporating the features of Davies' treatment that meets the needs of the students but ignores the complexities of statistics and upgrades the qualitative, intuitive approach of Lambert for general chemistry to a semiquantitative treatment using Boltzmann…

The various issues like do mentors have a responsibility to take a new look at the chemistry curricula in light of the challenges and expectations of the 21st century workplace, and should our graduates possess other valued characteristics are discussed. Every academician has the responsibility to prepare chemists for the 21st century by…

This narrative presents the educational route followed by an Intel Science and Engineering Fair (Intel ISEF) winner who was not always recognized for his scientific abilities. Factors contributing to the success of this gifted student are presented, as well as his creative insights for solving the problem that gave rise to the winning project.…

Understanding natural and human-induced hazards is an important part of the standards-based science curriculum. Experience, however, indicates that the topic is a difficult one for many students. We have developed an exciting investigative laboratory exercise that uses simulated food-based case studies to promote critical thinking and improve…

The practice of science has been characterized as the systematic application of common sense. This view, frequently held by scientists themselves, holds that the same qualities that allow pre-industrial societies, pioneers, cast-aways, and common folk everywhere to cope with their environment and prosper also make for good scientists. However,…

A survey was conducted with 67 science teachers who taught deaf children at the elementary school level. Teacher background variables, information about teacher preparation and certification, preferred teaching methods, communication methodologies, curriculum, and the use of technology were gathered. A purposeful, convenience sampling technique…

Robertson discusses the "perceived dichotomy" that permeates science teaching: teachers can either stress inquiry learning with lots of hands-on experiences or stress content knowledge and swap hands-on inquiry for direct instruction. Although a curriculum of unstructured hands-on science activities leads to shallow content knowledge, it is…

Course designers adopted a language-learners approach to the online teaching of New Zealand secondary school students in the subject of astronomy. This was possible because the curriculum for astronomy that was in 2004 established as a part of New Zealand's national curriculum was specifically designed to engage underachieving students in science…

This paper aims to examine the nature of the new elementary school curriculum in Turkey. In particular, the authors provide a coherent picture of the fundamentals, basic elements and the classroom implications of the new curriculum development initiative in five content areas: mathematics, science, social science, life science, and Turkish. This…

Science testing, as mandated by the No Child Left Behind (NCLB) Act, has refocused attention on the quality of the K-8 science curriculum and instruction in many districts around the country. It has become clear that to improve quality, and meet NCLB requirements, elementary and middle schools must develop different teaching approaches and…

Though deceptively simple to teach, chromatography presents many nuances and complex interactions that challenge both student and instructor. Time and instrumentation provide major obstacles to a thorough examination of these details in the laboratory. Modern chromatographic method-development software provides an opportunity to overcome this,…

A comparative study was conducted to compare two approaches to engineering design curriculum between different schools (inter-school) and between two curricular approaches, "Project Lead the Way" (PLTW) and "Engineering Projects in Community Service" (EPIC High) (inter-curricular). The researchers collected curriculum…

Describes the main features of the personalized system of instruction (PSI) or Keller Plan, and outlines the advantages and disadvantages encountered in implementing this instructional format in a freshman non-major biology course. (JR)

Two introductory biology courses which are given as service courses for agriculture students have been broken down into small conceptual units (mini-courses). Students cannot fail the course and are awarded a C grade when they have reached a predetermined level of mastery in each level for any unit, they may revise the unit and retake the test. If…

Describes the 1978 Educational Conference held at the University of Nottingham, England, which was devoted to Science Education for the 16-19 year olds. Also, summaries of conference discussions and papers are presented. (HM)
