“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 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 …

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 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 purpose of this explanatory case study using critical theory as a philosophical lens was to focus on two science teacher candidates‘ understandings of Otherness and their culturally responsive teaching (or the lack thereof) of students they believe are the ‗Others‘. The researchers found that even though the participants had different goals for their students, they were not responsive to some of their students because of the students‘ culture, race, and/or ethnicity. Both of the participants believed their science teacher education program had shortcomings and did not provide all of the needed experiences for them to be successful in their …

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 …

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 study examined the effect of diaries on self-regulation strategies of the pre-service science teachers. The participants of the study were 60 pre-service science teachers, 30 of which were in the experimental and the remaining 30 were in the control group. The Pintrich’s self-regulation model was taken as a basis in the study. The Pintrich’s model of self-regulation includes 3 general categories of strategies: (a) cognitive learning strategies, (b) metacognitive or self-regulatory strategies to control cognition, and (c) resource management strategies. In the study, the pre-service science teachers in the experimental group reported the self-regulation strategies they used for daily …

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 …

Fostering young people‟s commitment to protect biodiversity is an important goal of Education for Sustainable Development (ESD) in both, industrial countries and designated biodiversity hotspots. However, little empirical evidence exists to describe factors that influence such commitments. Based on the Value-Belief-Norm (VBN) theory, 15 to 19-year-old Chilean (n= 216) and German (n= 217) pupils‟ commitment to protect biodiversity was investigated. Comparisons revealed that Chilean adolescents showed higher personal norms and commitments to protect biodiversity. Regression analysis showed that within the German sample, the „Schwartz‟-value universalism was an important predictor for three different kinds of behavioural commitment. In both samples, „ascription …
