“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 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 …

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 …

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 …

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 …

Sociocognitive conflict has been used as a teaching strategy which may contribute to change students’ conceptions about science concepts. The present paper aims at investigating the structure of the dialogic argumentation developed by students, when they are involved in science teaching sequence that have been designed to change their conceptions through sociocognitive conflict strategy. For this purpose, teaching sequence targeted at the elaboration of students’ conceptions about floating and sinking -based on sociocognitive conflict processes- were prepared and implemented among 14 years old students. Next, the dialogues which the students had during the teaching sequence were analysed with the help …

Determination of conceptual problems which may cause alternative conceptions in science and technology textbooks is significant to increase in success of pupils and teachers. It is a vital issue to arrange books in a way removing or decreasing these faults in order to improve a better education via textbooks. This study aims to determine conceptual problems which may cause alternative conceptions in biology topics in science and technology textbooks of primary schools. In this study, the units of each textbook were analyzed page by page according to document examination method and conceptual problems were determined. The founded conceptual problems have …

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 …
