This article pursues a dual objective. First, it seeks to present the notion of the relationship to knowledge as a valuable theoretical tool for science education research. Secondly, it aims to illustrate how this notion has been operationalized in recent research conducted in Quebec (Canada) that focuses on teachers‟ and students‟ relationship to knowledge. The first portion of this article presents the notion of the relationship to knowledge, documenting its origins, usefulness and contributions to research in the field of science education. In the second portion, we present four (4) studies recently conducted in Quebec that relied on the notion …

The present study aimed to determine level of pre-service chemistry teachers‟ environmental literacy and their perceptions on environmental education. This study was realized during the fall semester of 2006-2007 academic year with the participation of 60 students enrolled in five-year chemistry teacher education program. The data collected by administration of Environmental Literacy Test and Environmental Education Perception Survey were analyzed by descriptive statistics and content analysis. The pre-service chemistry teachers strongly emphasized promotion of feelings of concern for the environment, development of awareness and sensitivity to the total environment, and gaining social values to protect the natural resources through teaching …

This paper investigates the enrolment trends and the critical factors that impinge on students‟ choice of physics as major field of study. The data were generated from primary and secondary sources. Primary data was acquired based on a semi-structured interview with 14 sophomore and 11 senior students and five instructors of the department of physics at Hawassa University, Ethiopia. In addition, data on allocation of students to various major fields as well as quantitative data on academic achievement were obtained from the university‟s registar office. The results indicate that the rate of enrolment in physics is the lowest and applicants …

The purpose of the present study was to examine and compare the effectiveness of virtual frog dissection using V-Frog© and physical frog dissection on learning, retention, and affect. Subjects were secondary students enrolled in year-long life science classes in a suburban high school (N=102). Virtual dissections were done with V-Frog©, a virtual reality software application that allows users to work with a virtual specimen that can be cut and explored in ways that are therefore unique for each individual user. The study employed a pretest, posttest, delayed posttest design using the pretest as a covariate in the analysis of the …

This study examined the level of awareness, knowledge and practices of secondary schools students with regard to waste management. Few studies have captured waste management problems in Nigerian educational institutions, particularly the views of students. Using a structured, self-administered questionnaire, 650 students were surveyed from six secondary schools in two of the four educational zones of Ogun State. Data collected were subjected to percentage, mean, standard deviation, t-test and chi-square statistical analyses. Findings revealed that secondary school students from the sampled zones were aware of waste problems on their school compounds, but possessed poor waste management practices. The study showed …

The focus of this paper is on selected recent South African research studies that have explored efforts to promote the discussion, writing, and arguing aspects of scientific literacy in primary and middle schools, particularly amongst second-language learners. These studies reveal improvements in the participants’ abilities to both use the ‘science notebooks’ approach and argue their findings, as well as statistically significant improvement in their problem solving skills. The positive findings of these studies, and the call for attention to be paid to the fundamental sense of scientific literacy by a number of international researchers, resulted in the development of an …

The late 20th century and beginning of 21st century have witnessed unprecedented rapid economic development due to advances in technology and globalization. In response to this development, a renewed call for science literacy has become louder in the USA and many other countries. Common to all science education reforms around the world is emphasis on achieving science literacy by all children before high school graduation. This paper first reviews definitions of science literacy in the literature; it then examines the status of science literacy in the USA and other countries. Following the above, this paper then presents a new notion …

In the United States and around the world, calls for educational reform stress the need for a scientifically literate population, prepared for the twenty-first century workforce. These calls have translated into new curricula, which in isolation, are not enough? Teachers play an essential role in the development of scientifically literate citizens. Their purposes for teaching science act as filters for acceptable learning and teaching activities. This paper examines the congruence of eight private school teachers’ purposes for teaching science, and aspects of scientific literacy in the Middle Eastern country of Lebanon. Findings are discussed in light of contextual factors that …

Since the first use of ‘scientific literacy’ in the late 1950s, numerous science educators and policy makers have reconceptualised the term to such an extent that it has been described as being ‘ill-defined and diffuse’. Despite this lack of clarity, the term is the focus of curriculum standards in many countries and is at the heart of international comparisons of student attainment including the Organisation for Economic Cooperation and Development’s (OECD) Programme for International Student Assessment (PISA) study. Uncritical use of the term masks the existence of deep-seated philosophical clashes that hinder reform of science education in many countries throughout …

This paper revisits the discussion about the objectives of scientific literacy-oriented chemistry teaching, its connection to the German concept of Allgemeinbildung, and the debate of science through education vs. education through science. About 10 years ago the sociocritical and problem-oriented approach to chemistry teaching was suggested using these starting points. In this paper its central assumptions and criteria for structuring lesson plans are presented as they have been refined along a series of lesson plans developed by participatory action research in recent years. The summarized teaching approach intends to more thoroughly promote reflection on scientific questions in the framework of …
