In this decade of Education for Sustainable Development, it is timely to consider the methodological issues associated with researching this topic not only with adults but also with the young children who, as members of the next generation, will experience the success or otherwise of current environmental sustainability efforts. We argue that it is important when making methodological choices to recognize that both the sustainability issues themselves and the way individuals learn about these issues, are socially and culturally constructed. In this article we are interested in ways of gaining representations of individuals’ mental constructions of environmental sustainability issues. We …

Based on students‟ alternative conceptions of the topics „electric circuits‟, „electric charge flows within an electric circuit‟, „how the brightness of bulbs and the resistance changes in series and parallel circuits‟, the current study aims to present a combination of different conceptual change methods within four-step constructivist teaching model. Therefore, the author assumes that such a design may give a chance to eliminate students‟ alternative conceptions fully. Also, some suggestions were made for further research.

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 …

Environmental education is considered an appropriate intervention for creating awareness of, and an understanding of the challenges of environmental degradation. The introduction of EE into the Nigerian school curricular creates a challenge of how to teach it. A majority of the teachers still employ the old, traditional “chalk and talk” method. This study experimented with two modes of participatory strategies, the full and quasi participatory modes in teaching secondary school students in Nigeria some EE concepts. Three hundred and sixty students were randomly selected and assigned to the three treatment groups. Five hypotheses were tested at P<.05 and data …

A questionnaire was used to explore the prevalence of ideas about global warming in Year 10 (age 15-16 years) school students in Turkey. The frequencies of individual scientific ideas and misconceptions about the causes, consequences and ‘cures’ of global warming were identified. In addition, several general findings emerged from this study. Firstly, many students believed that radioactivity is causally linked to global warming; they believed that radioactive leakage from nuclear power stations exacerbates global warming, and that reducing the global nuclear arsenal could reduce it. Secondly, students appeared to confuse the causes and consequences of global warming with those of …

An intervention study was set up through the School Civic Clubs to improve Botswana Children’s environmental knowledge, attitudes and practices. The underlying assumption in using this informal approach was based on the premise that the school time table is already overcrowded and that the infusion approach currently adopted in the country has not produced the desired results. Hence, the Civic Clubs were introduced into ten Primary schools in Botswana. Using this informal approach, the children were given requisite training in civic and environmental issues, and they engaged in various activities for a period of six weeks. Data was collected before …

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 …

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.

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 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 …
