Designing and interpreting controlled experiments are important inquiry skills addressed in many current science curricula. The relevant skills associated with the design and interpretation of controlled experiments are summarised under the term control-of-variables strategy (CVS). Research on elementary school students' CVS skills shows that they…

The aim of the study was to examine nature of science (NOS) views of science teachers in project schools in Turkey. The sub-research questions of the study targeted at the relationships between the teachers' views on NOS in terms of different demographic features of the participant teachers. The participants were composed of convenience sample of…

This paper seeks to investigate how students' performance in Chemistry can be enhanced by using kitchen resources in Calabar. The kitchen resources used included a piece of white paper, a swab, lemon juice and candle. These were used to show that paper cellulose was oxidized by flame due to the catalysis of lemon juice acid. Other materials used…

Cognitive style differences, also known as 'empathizing' and 'systemizing' have been argued as one reason that may explain differences in children's motivation to learn science. Researchers claim that people with a 'systemizing' cognitive style are likelier to engage in science than those with an 'empathizing' cognitive style. As such, they…

Trends in International Mathematics and Science Study (TIMSS) is an international comparative study that has been implemented by the International Association for the Evaluation of Educational Achievement (IEA) since 1995. This proposed study is aimed to identify the correlations of science classroom teachings with eighth graders' science…

Contribution: This article aims to explore learner variables that predict the effectiveness of university class using the Havruta method. Background: This article was conducted on 105 learners enrolled in the "General Physics and Experiments 2" class at K University in South Korea. Research Questions: Independent and dependent variables…

Introduction: In the Baccalaureate, the exact and experimental science subjects demand the development of scientific competence, which in turn requires mastery of theoretical knowledge and practical knowledge, but also motivation and sustained effort for greater involvement and academic performance. Hence the relevance of knowing the motivational…

The purpose of this paper is to present and discuss an alternative solution to an experimental problem given to high school students in the XXII Ibero-American Physics Olympiad held by Colombia this year. From the measurements of electric current and potential difference across a small tungsten filament lamp students should find the dimensions of…

We describe here a collective and experimental research project-based learning (ERPBL) for master's students that can be used to illustrate some basic concepts on glucose/lipid homeostasis and renal function around a topical issue. The primary objective of this ERPBL was to strengthen students' knowledge and understanding of physiology and…

The current study examines the performance and achievement of students in the Systematic Qualitative Analyses of Cations (SQACs). We sought answers to questions such as, "What are the students' levels of performance?" and "What is the relation between the average scores for performance and achievement?." This was done by using…

In this article, the authors consider the possibility that groups could be different, because of the different conditions of a factor. This is as far as the analysis can extend: the consideration is restricted to groups characterized by the different category of the factor being considered. In many biological experiments, the factor considered may…

Capitalizing on the comments made by teachers on videos of exemplary science teaching, a video-based survey instrument on the topic of "Density" was developed and used to investigate the conceptions of good science teaching held by 110 teachers and 4,024 year 7 students in Hong Kong. Six dimensions of good science teaching are identified…

Teachers' professional knowledge is assumed to be a key variable for effective teaching. As teacher education has the goal to enhance professional knowledge of current and future teachers, this knowledge should be described and assessed. Nevertheless, only a limited number of studies quantitatively measures physics teachers' professional…

This is the start of a road map for the effective introduction of inquiry-based learning in chemistry. Advantages of inquiry-based approaches to the development of scientific literacy are widely discussed in the literature. However, unless chemistry educators take account of teachers' reservations and identified disadvantages such approaches will…

In this study, relationship between prospective science and technology teachers' experiences in conducting Hands on physics experiments and their physics lab I achievement was investigated. Survey model was utilized and the study was carried out in the 2012 spring semester. Seven Hands on physics experiments were conducted with 28 prospective…
