In this study, the effectiveness of concept cartoons in diagnosing and overcoming students’ misconceptions related to photosynthesis subject was examined. Firstly, the literature has been thoroughly examined and misconceptions about photosynthesis subject have been listed and then grouped. Concept cartoons related to these groups have been prepared and were introduced to the students in order to identify their misconceptions. Similar misconceptions as in the literature have been found. Then, new concept cartoons addressing to elimination of these misconceptions have been prepared and were used in class discussions. The excerpts from these discussions and after-class student interviews show that concept cartoons …

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.

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 …

Ginseng is one of the most widely used herbal medicines and is reported to have a wide range of therapeutic and pharmacological applications. Ginseng may also be potentially valuable in treating cardiovascular diseases. Research concerning cardiovascular disease is focusing on purified individual ginsenoside constituents of ginseng to reveal specific mechanisms instead of using whole ginseng extracts. The most commonly studied ginsenosides are Rb1, Rg1, Rg3, Rh1, Re, and Rd. The molecular mechanisms and medical applications of ginsenosides in the treatment of cardiovascular disease have attracted much attention and been the subject of numerous publications. Here, we review the current literature …
