The main objective of this work is to analyse the visual representations (VRs) of the microcosm depicted in nine Greek secondary chemistry school textbooks of the last three decades in order to construct a systemic network for their main conceptual framework and to evaluate the contribution of each one of the resulting categories to the network. The sample comprises a total number of 221 VRs of microcosm, 66 of which are VRs of the 8th grade, 92 of the 9th grade and 63 of the 10th grade. For the qualitative analysis of VRs the phenomenographic method was implemented, whereas a basic quantitative analysis followed. Results provide us with a network that can help science teachers and textbooks designers in identifying the plethora of codes employed in these VRs and the plethora of ways in which VRs can be used, as well as, in determining possible causes of relevant students' misconceptions. Quantitative analysis indicates an effect of grade on the content of VRs and relevant implications for science education are discussed.

Local wisdom of an area is important to be preserved so that the values contained in it can be learned and understood by the younger generation. This study aimed to identify the local wisdom of the society of Kubu Raya Regency, especially those who use peatlands for livelihoods. The results of this identification are associated with the Basic Competencies (KD) of Science Subjects of Junior High School (SMP)  in the 2013 curriculum. The subjects of this study were 10 science teachers who teach in Kubu Raya Regency and the society who use peatlands for livelihoods with a purposive sampling technique. Descriptive research methods are used to achieve research objectives. Data collection techniques using observation sheets, interviews, and questionnaires. Research results on the local wisdom of the society of Kubu Raya Regency relating to peatlands were 7 (seven) KD for 7th grade, 2 (two) KD for 8th grade, and 1 (one) KD for 9th grade, science concepts and character values in each KD. Based on expert validation, it can be concluded that there was a match between local wisdom and KD, the concept of Sciences and character values in science subjects of the 2013 curriculum.

The development and evaluation of valid assessments of scientific reasoning are an integral part of research in science education. In the present study, we used the linear logistic test model (LLTM) to analyze how item features related to text complexity and the presence of visual representations influence the overall item difficulty of an established, multiple-choice, scientific reasoning competencies assessment instrument. This study used data from n = 243 pre-service science teachers from Australia, Canada, and the UK. The findings revealed that text complexity and the presence of visual representations increased item difficulty and, in total, contributed to 32% of the variance in item difficulty. These findings suggest that the multiple-choice items contain the following cognitive demands: encoding, processing, and combining of textually presented information from different parts of the items and encoding, processing, and combining information that is presented in both the text and images. The present study adds to our knowledge of which cognitive demands are imposed upon by multiple-choice assessment instruments and whether these demands are relevant for the construct under investigation—in this case, scientific reasoning competencies. The findings are discussed and related to the relevant science education literature.

This study aims to explore the use of video in English language teaching (ELT) elementary school (grades 8 to 9)... In addition, the thesis aims to find out how videos in English lessons helped to achieve the goals of English curriculum. The main hypothesis was that teaching with video would develop pupils’ communicative skills and, therefore, was appropriate for the communicative approach to ELT. The study addressed five research questions regarding the use of videos in English lessons in the case study school: why the teachers used videos in ELT, what kinds of videos were used in English lessons, how and how often videos were used, what was taught and learned through the use of videos and, finally, what the teachers’ and pupils’ attitudes to lessons with videos were. The research was performed as a case study at an Elbasan elementary school. The data for the research was obtained through the use of mixed methods: qualitative, in the form of interviews with four English teachers and observations of three of the interviewed teachers’ lessons with videos, and quantitative, in the form of a pupil questionnaire answered by 105 pupils from two 8th grade and two 9th grade classes.

The aim of science education is to enable children to become “science-literate.” Science literacy is defined as taking responsibility for and making decisions about situations requiring scientific understanding and having sufficient knowledge, skills, attitudes and understanding of values to put their decisions into practice. Revealing teachers’ beliefs can help to understand the types of experiences presented by teachers in their classrooms. Inadequate understandings and misbeliefs of teachers shape the first perceptions of children about the NOS when they are formally introduced with science education in their early childhood. Most of the studies were also performed with science teachers and there have been few studies conducted with preschool teachers. Therefore, the present study was directed towards determining NOS beliefs of preschool teacher candidates. To achieve this aim, Nature of Science Beliefs Scale (NOSBS), developed by Özcan and Turgut (2014), was administered to the preschool teacher candidates studying in Preschool Education Department of Buca Education Faculty at Dokuz Eylül University in the spring semester of the 2018-2019 academic year. In the study, the NOS beliefs of the teacher candidates were found to be acceptable in general. While the findings of this study are consistent with those revealed in several relevant studies in the literature

The goal of this work is to describe pre- and in-service science teacher education and science education research in Indonesia in an effort to better inform the global science education community about historical developments and present challenges. We begin by providing an historical overview of the general education system to provide readers with context needed to understand current reform initiatives. Next we describe the current-day process for preparing and certifying science teachers and we describe some of the challenges facing teachers, students, and researchers in Indonesia’s science education context today. We follow this discussion with an introduction to some existing professional organizations for teachers and researchers in Indonesia that are working to develop important channels for disseminating current research on teacher practice, curriculum innovation, and student learning that have the potential to positively influence on teaching and learning in the future. We conclude by highlighting some areas that would benefit from additional research and by inviting more international collaborative research initiatives with colleagues in the Asia-Pacific region and beyond.

To understand how integrated science education (ISE) can be transferred into successful classroom practices, it is important to understand teachers’ perceptions and self-efficacy. The focus of this study is twofold: (1) to understand how teachers perceive ISE and (2) to assess if science teachers’ perceptions of and experiences with integrated education correlate with their views on self-efficacy in relation to ISE. Ninety-five Finnish science teachers participated in an online survey study. A mixed method approach via exploratory factor analysis and data-driven content analysis was used. Self-efficacy emerged as a key factor explaining teachers’ perceptions of and their lack of confidence in implementing ISE as well as their need for support. In addition, teachers regarded ISE as a relevant teaching method, but challenging to implement, and teachers primarily applied integrated approaches irregularly and seldom. Furthermore, teachers’ experiences with integrated activities and collaboration correlated with their views on integrated education and self-efficacy. These findings indicate teachers need support to better understand and implement ISE.

Purpose: The Nature of Science (NOS) is an important component of scientific literacy. Science teachers’ Views of the Nature of Science (VNOS) directly affect their teaching behaviors. Therefore, it is of great significance to explore science teachers’ VNOS and find ways of improvement. This study was designed to comparatively investigate preservice science teachers’ VNOS between China and Canada. Design/Approach/Methods: The study employed a survey design to explore how Chinese and Canadian preservice science teachers understood the seven different aspects of NOS. Findings: Data showed that preservice science teachers in China and Canada both hold a modern view about science education. The level of Chinese and Canadian participants’ understanding of NOS was above the relatively naive level. Chinese teachers had better macro-understanding toward science education but their micro-mastery was insufficient. While the Canadian participants had a better understanding of the NOS than their Chinese counterparts. Originality/Value: Based on the research results and the experience of science education and teacher education in Canada, we suggested that there is a need to reconstruct the preservice science teacher education curriculum in China and promote the transformation in the science teacher educational system.

AbstractIn this paper, we discuss the role of dialogue in two layers; first, in relation to two self-organised communities of science teachers in which we participated and, second, our process of coming together during our PhDs to analyse these communities, a dialogue about the dialogue. Regarding the first layer, there is much to learn from science teachers and science teacher educators when they are organised in sites of learning that can be spaces of hope, beginnings, and becoming, as is illustrated in the case of these two self-organised communities. Regarding the second layer, we discuss the value of dialogue and the possibilities it offers to develop ideas for science education in a way that might be democratising, emancipatory, and offering counter-narratives in a neoliberal Chile. By engaging in this dialogue revisiting the practices of our communities, we gained a sense of agency within the field of science education. However, we realised that we need to move towards a critical view within our communities, and more contextual and transformative science education by translating these sites of hope to our educational praxis today. For us, this relates both to developing a collective view of how to make science education provide pedagogical conditions and experiences for critical and engaged citizenship and thinking how we can act and engage with different settings in solidarity. One way of moving towards this is by developing a political knowledge of our disciplines through a collective scientific conscientisation. Our communities are the departure points to achieve this.

ABSTRACTA comparative study investigating the integration of supplemental teaching resources in materials science education was developed for the purpose of determining the effectiveness of teaching strategies. Digital stories created by students, excerpts from the Nova Making Stuff documentaries, YouTube educational videos and student generated demo-kits were used as part of the investigation whereby two 9th grade science classes (n~26) were evaluated. Each participant in the study received one period (40-min) of a traditional lesson on Materials Science including specific content, vocabulary, and a pre- and post- lesson assessment. Additionally, the students in each class participated in a 30-min supplemental component, e.g. video or activity-based demonstration using aforementioned kits or video compilation. Pre- and post- evaluations (e.g. open-ended and likert questions) were administered to all of the participants. As hypothesized, the students’ feedback and performance on assessment activities reveal that the use of multimedia and activity-based resources may be equally effective teaching methods as traditional methods.
