In this paper, I discussed different types of models in science education and applications of them in learning and teaching science in particular physics. Based on the literature, I categorized models as conceptual and mental models according to their characteristics. In addition to these models, there is another model called “physics model” by the physics-education community. And then, I discussed applications of these models for learning and teaching science particularly physics along with examples that can guide teachers and students in their science courses.

Current research has begun to reveal a link between environmental education and increases in science achievement and understanding (Glynn 2000; Liederman and Hoody, 1998). The researchers in this study of participants in a coastal marine teacher workshop found that increases in environmental topics or lessons in teachers’ classrooms post-program were minimal. Several limitations to infusion were revealed, including teachers’ perceived obligation to strictly follow science standards, and an increased emphasis on preparation for standardized tests. The results suggest that greater emphasis is needed on providing opportunities for participants to make explicit connections with their instruction within the parameters of the …

The purpose of this study was to determine the knowledge levels of popular biotechnological issues of Turkish science and elementary teacher candidates. A questionnaire was administered during 2006-2007 school term to 336 students pursuing their education in the departments of science and elementary education in two Turkish universities. The questionnaire covers six biotechnological issues such as biotechnology, agrobiotechnology, human health and pharmacy, environment and biotechnology, and food production with biotechnology. Results revealed that whereas science and elementary teacher candidates had an approximate consistent knowledge of describing biotechnology and human health/pharmacy that almost all students had an inadequate knowledge about other …

The case study reported in this paper is part of a larger multiple cross case analysis focusing on pre-service teachers with various initial confidence and attitudes toward science and science teaching. In this paper, the focus will be on one elementary teacher candidate, Lisa, who began the science methods course with a negative attitude and low self-efficacy. An in-depth description of her beliefs, attitude, and self-efficacy, before and after the course, the impact of her prior science experience and the science methods course on shaping these domains, and the possible interrelationship between the three variables are discussed. The findings revealed …

This paper serves to review previously reported studies on students’ misunderstandings about the energy conservation principle (the first law of thermodynamics). Generally, studies in literature highlighted student’ misunderstandings about the energy conservation principle stem from preliminaries about energy concept in daily life. Since prior knowledge of students’ misunderstandings of scientific content knowledge is the first step in preventing these misunderstandings, it is considered that such a study will provide an important source for studies which aims to reduce or eliminate misunderstandings on the energy conservation principle.

Phytomedicines are believed to have benefits over conventional drugs and are regaining interest in current research. Moringa oleifera is a multi-purpose herbal plant used as human food and an alternative for medicinal purposes worldwide. It has been identified by researchers as a plant with numerous health benefits including nutritional and medicinal advantages. Moringa oleifera contains essential amino acids, carotenoids in leaves, and components with nutraceutical properties, supporting the idea of using this plant as a nutritional supplement or constituent in food preparation. Some nutritional evaluation has been carried out in leaves and stems. An important factor that accounts for the …

Value chain analysis has been applied in various fields, from the time the concept of “value chain” was introduced by Porter in 1985. Several frameworks have emerged and have been used to study individual firms, entire industries, industry clusters, as well as global production networks. The purpose of this paper is to provide a brief review of these frameworks, identify factors that influence the performance of value chains, and suggest areas for future research. Since there is a wide range of value chain literature, this paper focuses on a selective set of earlier works within the value chain model as …
