This study explored the effectiveness of an inquiry-based cellulase laboratory unit in promoting inquiry in undergraduate students in biotechnology. The following tools were used to assess the students’ achievements and attitude: conceptual understanding test, concept mapping, students’ documents, CLES questionnaire, students’ self reflection, and interviews. Judging from their conceptual understanding test results and concept mapping, students gained significantly more content knowledge on enzyme-substrate interaction and its application. In addition, students’ reports on their projects revealed that they have developed their critical thinking, scientific process skills and abilities to apply knowledge on enzyme cellulase to industrial application. The students reacted positively …

“Non-native organisms are a major threat to biodiversity”. This statement is often made by biologists, but general conclusions cannot be drawn easily because of contradictory evidence. To introduce pupils aged 11-14 years to this topic, we employed an educational program dealing with non-native animals in Central Europe. The pupils took part in a lesson giving general information about the topic, followed by a species identification quiz. Attitude, emotions and state of knowledge of each pupil were surveyed throughout the program using standardized questionnaires (pre-/post- and follow up tests). One week after the first lesson, a field trip followed, focusing on …

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 describes the design of an educational module which aims to raise awareness and change the attitudes of elementary school students about focal endangered species in protected areas. The proposed design builds on, and extends the General Teaching Model. The educational module which was developed through this approach was pilot-tested in two Greek elementary school classes, involving 29 students who provided their opinion through a questionnaire. The results verify that the educational module had a significant effect on the cognitive level and the attitudes of the students. Therefore, it is argued that the proposed design approach can form the …

Research on playfulness, science, and creativity suggests that there is a connection between having positive background experiences with science and the development of interest in science. However, there is little empirical research on where, how, and when teachers’ interests in science develop. The purpose of this research was to explore connections between preservice elementary teachers’ background science experiences and interest in science. Subjects were 53 preservice teachers in two sections of a science methods course. The data were collected by administering a self-report Science Background Experiences Survey. Students with low and high initial interest in science were significantly different on …

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 …
