Helping student to improve the problems solving skills is the primary target of the science teacher trainees. In modern science, for training the students, methods should be used for improving their thinking skills, make connections with events and concepts and scientific operations skills rather than information and definition giving. One of these methods are problem solving.With this study, it is shown that problem solving is not just solving a movement problem like in the physics as it is understood by most of the science teachers but it can be used also in social problems like environmental problems. Further more, scientific …

Now in its fifth year, PR2EPS is a National Science Foundation funded initiative designed to recruit high school students to attend college majoring in the physical sciences, including engineering and secondary science education, and to help ensure their retention within these programs until graduation. A central feature of the recruitment effort is a free, one-week residential summer science camp for high school students. This report describes the rationale for using a camp as a recruitment tool as well as the camp structure. Two focus questions are addressed: 1) How successful is the camp at providing a learning environment where participants …

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 …

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 …

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 …

The aim of this research is to reveal that to teaching activities which are designed according to the Multiple Intelligence Theory have effects on the students success in mathematics and on the permanence of the knowledge learned. This research has been carried out the fourth graders at Gazi University Foundation Private Primary school. Among all the classes, two of them were selected, 4-A was selected as an experimental group and 4B as a control group considering their pre-test points. The groups attending to the research were applied a permanence test which examines the behaviors that have to be gained before …

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.

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 …

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 …
