This study was conducted in order to determine the differences in integrated scientific process skills (designing experiments, forming data tables, drawing graphs, graph interpretation, determining the variables and hypothesizing, changing and controlling variables) of students (n = 17) who were taught with an approach based on scientific argumentation and of students (n = 17) who were taught with a traditional teaching approach in Grade 11 chemistry. The study was conducted at a high school in Çankırı, Turkey. A multiformat Scientific Process Skills Scale was administered to both groups as a pre- and posttest; it contained 29 items in 5 modules …

The purpose of this study was to examine the association of middle school student science achievement and attitudes about science with student-reported frequency of teacher lecture demonstrations and student-centered learning. The student sample was composed of 602 seventh- and eighth-grade students enrolled in middle school science. Multiple regression was used to investigate the association of attitudes toward science, student-centered learning, and teacher demonstrations with science achievement. Both attitudes toward science and student-centered learning were positively associated with science achievement, and student-centered learning was positively associated with attitude toward science. Teacher demonstrations were found to have a negative association with student …

Recently, schools nationwide have expressed a renewed interest in school gardens, viewing them as innovative educational tools. Most of the scant studies on these settings investigate the health/nutritional impacts, science learning potential, or emotional dispositions of students. However, few studies examine the shifts in attitudes that occur for students as a result of experiences in school gardens. The purpose of this mixed method study was to examine a school garden program at a K-3 elementary school. Our study sought to demonstrate the value of garden-based learning through a focus on measures of learning typically associated with the informal learning environment. …

In light of the crucial role of teacher education in transforming education and society so that a sustainable future is possible, there is increasing interest in the relationship between academic major and development of student teachers’ environmental literacy (EL). Since science disciplines are the common framework for incorporating environmental education, this longitudinal study investigated, in a paired pretest-posttest design, if student teachers majoring in the environment-related disciplines differ in the development of their EL from other majors. The differences in EL-variables between the two groups were enhanced during studies only in particular behavioral aspects (recycling efforts and citizenship action) and …

The purpose of this study was to investigate the levels of energy literacy among 276 Form 2 (Grade 8) Malaysian students as no similar study has been previously conducted in the country, as well as the contribution of students’ energy-related knowledge and attitudes on their energy-related behaviors. This was a non-experimental quantitative research using the sample survey method to collect data by using the ‘Energy Literacy Questionnaire’ (ELQ). Independent samples t-test, Pearson product-moment correlation, and multiple linear regressions were used to analyse the data. The study found that levels of energy literacy were relatively low suggesting that the implemented curriculum …

The purpose of this study was to examine the changes in 19 preservice chemistry teachers’ understandings of the structure of matter, including the aspects of the physical states of matter, the physical composition of matter, and the chemical composition of matter, before, immediately after, and months after they received a specific instruction. The one-group pre, post, and delayed posttest design was used, and participants’ understandings before, immediately after, and months after the instruction were assessed using the same “three part particulate drawing” classification question constructed by Sanger (2000). Collected data were analyzed according to both the number of scientifically appropriate …

This paper focuses upon the problem of raising environmental awareness in the context of school science. By focusing, as it does, on the relationship between the self and the natural environment, the paper discusses the difficulties that exist, such as the students’ involvement with the natural world, as their object of study, the empirical treatment and the modeling of the natural world, and the purpose of learning science, as well as the possibilities for promoting the development of such relationship by keeping the natural world, as an object of study, in the foreground of the teachinglearning process. Such possibilities refer …

Internationally, learning science through investigation is promoted as a preferred pedagogical approach. Research presented takes a view that such learning depends on how teachers understand science investigation. Teachers‘ understanding of science investigation was an aspect of an interpretive case study of the phenomenon of science investigation exploring the links between learning, motivation and assessment in year 11 science. Data were collected through a population survey of year 11 science teachers (n=165) in the greater Wellington region through a postal questionnaire (response rate 61%). In addition, all year 11 science teachers in a typical coeducational, middle size, urban secondary school were …

This study investigates noise pollution levels in two elementary schools. Also, “noise level awareness and sensitivity training” was given for reducing noise pollution, and the effects and results of this training were evaluated. ‘Sensitivity’ training was given to 611 students and 48 teachers in a private and a public school. Questionnaires, sound meter observations, and the reflections of the student teachers participating in the study were used for collecting data. The findings showed that noise levels measured in both schools were much higher than national and international upper limits. The data obtained through the first questionnaire indicated that students and …

In this paper, it is aimed to investigate the persistence of misconceptions in the topic of the human blood circulatory system among students in different grade levels. For this reason, after discussions with biology educators, two tests consisting of open-ended questions were developed by the researcher and administered to students in four different grade levels. The first test was administered to 319 5th and 7th grade students in elementary school and the second one was administered to 400 1st and 4th year university students studying in the departments of elementary school teaching, science education and biology education. Data were analyzed …
