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).

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 …

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 …

Опубликована Янв. 10, 2013

Achieving a sustainable future requires that individuals adopt sustainable behaviors, which are often learned and cemented at a young age. Yet, traditional education efforts have been inadequate in fostering transformative change, in part because many programs focus on fact-heavy, teacher-centered techniques while neglecting the practices that behavioral and sustainability scholars highlight as central to creating change. To address this gap, the present research integrates three critical yet mostly disparate bodies of research— educational pedagogy, behavior change, and sustainability competencies. This interdisciplinary approach to education was implemented and evaluated with a small group of students during an intensive summer program and …

Science teachers frequently select science news articles as supplementary teaching materials; however, the literature indicates that students encounter difficulties in examining and evaluating the news content and textual elements. This paper reports an instructional strategy of utilizing science news articles and investigates its effectiveness in enhancing students’ cognitive learning outcomes. In this quasi-experimental study, 118 seventh graders from four classes in one secondary school in Taiwan took part in the Science News Instruction (SNI). After eight weeks of instruction about Genetics and Reproduction, all students were requested to present their written arguments to the selected science news article. Two of …
