To examine how the teachers perceive technology and engineering and distinguish them, transcriptions of the interviews were analyzed using phenomenography. Results The results show that all research participants appeared to distinguish technology and engineering in some ways, but with varying degrees. In addition, their perceptions expressed through the interviews were categorized into 11 elements in three domains of the NOTE. The teachers’ perceptions also appeared to be influenced by language. As many Korean words are based on Chinese characters, teachers often understood the terms through the meanings of the Chinese characters. Teachers were confused between the Korean terms and their corresponding English terms because what the terms connote are different in each language. Conclusion This study provides useful information concerning NOTE by analyzing how teachers perceive technology and engineering, which could be helpful in teaching STEM based on NOTE.","PeriodicalId":46656,"journal":{"name":"Research in Science & Technological Education","volume":"41 1","pages":"596 - 613"},"PeriodicalIF":1.6,"publicationDate":"2021-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/02635143.2021.1924656","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49087500","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Science teachers’ views of creating and teaching Big Ideas of science education: experiences from Chile","authors":"Paulina Bravo González, M.

Purpose This study explores the conceptualisation and practice of the use of Big Ideas of science education by primary and secondary teachers in Chile. Sample A total of 63 science teachers (a purposive sample) from pre-school, primary and secondary education in Valparaíso Region in Chile participated in the study, with 38 of them answering all the questions in the research instrument and 25 answering some of them. Design and methods The research instrument was a questionnaire with open-ended questions. Results The use of Big Ideas was seen as the ‘natural way’ to teach science, mostly related to the students’ daily lives. Many of the teachers had their own understanding of Big Ideas. They were very positive about Big Ideas, seeing them as a possible way of connecting with the daily lives of students and facilitating progression in students’ learning of science. The teachers also saw Big Ideas as enabling students to work collaboratively and make links between different parts of the curriculum, helping them to understand how science works, and preferable to having to teach an overloaded science curriculum that lacks such an organising framework. Conclusion The teachers were more interested in their own creation and development of Big Ideas rather than simply adopting the existing, official published framework and adhering to what is said in the Chilean curriculum regarding the approach of Big Ideas. These results indicate the need to explore in-depth such varied conceptualisations of schoolteachers regarding the approach of Big Ideas. In turn, this can offer empirical insights into the way Big Ideas are treated in policy documents in Chile and elsewhere.","PeriodicalId":46656,"journal":{"name":"Research in Science & Technological Education","volume":"41 1","pages":"523 - 543"},"PeriodicalIF":1.6,"publicationDate":"2021-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/02635143.2021.1919868","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49666815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

More research is needed to better understand the conditions under which teaching and learning of epistemological insights become possible, as well as the tools that are necessary for this purpose. Purpose This study investigates the potential impact of Explicit Epistemological Discourse (EED) in improving student understanding of the interrelationship between Science and Technology (S&T) through a combined inquiry-oriented and design-oriented teaching and learning activity sequence on Electromagnetic Properties of Materials. Sample The participants were 16 year-old students from two intact classes (N = 37 and N = 26, respectively) in their last year of state schooling, in a European country, one year before selection of high school elective courses. Design and methods We implemented two conditions of the activity sequence; one included EED activities on the interrelationship between S&T, the other condition included identical inquiry and design activities, with additional practice exercises substituting the reflection activities on EED. Pre-post tests and interviews evaluated students’ understanding about the goals of S&T. Results Students in the EED condition surpassed students in the non-EED condition. The results support the claim that students’ awareness about the interrelationship between S&T is improved when integrating EED into classroom activities that are credibly authentic and relevant from the students’ perspective. Conclusion Discursive reflection activities have an important role to play in helping students appreciate aspects of the nature of science and the nature of technology as part of their science classes. The integration of epistemological insights in the objectives of science education and the findings of this study are particularly relevant for contemporary efforts to promote education for innovation and entrepreneurship.","PeriodicalId":46656,"journal":{"name":"Research in Science & Technological Education","volume":"41 1","pages":"482 - 504"},"PeriodicalIF":1.6,"publicationDate":"2021-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/02635143.2021.1912726","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47023626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Purpose: In this article, we tried to make a reinterpretation of the findings of recent empirical studies conducted on the effectiveness of the flipped classroom approach in science education. Design and Methods: To determine the overall effect size of the flipped classroom implementations in Science courses, a meta-analysis of 30 studies with such moderator variables as education levels, durations of implementations, various subjects areas of science and class sizes was carried out. To consolidate the academic achievement theme dwelled on in the meta-analysis part, a meta-thematic analysis based on document analysis of qualitative studies was conducted to expound in detail general characteristics of the approach, its effect on academic dimension, its contribution to the affective domain and classroom environment. Results: The findings reveal that the flipped classroom implementations have a positive medium effect (g = 0.727) on academic achievement in Science classes. Physics and Chemistry classes have the highest effect size values while Biology has the lowest effect size; the flipped classroom practices proved best in small size classes and at Primary School level with the highest effect sizes. Conclusions: The findings of both analyses provide insights into applicability of the approach in teaching of Science and its sub-branches.

This creates a need to identify new aspects of working with scientific data that are important for K-12 students to learn. Purpose To address this need, we conducted a study with practicing scientists and K-12 science teachers. The purpose of the study is to identify new aspects of working with scientific data and the strategies involved in those aspects, which are potentially important for students to learn. The research questions are: (1) How do scientists work with data in their scientific inquiry? (2) What strategies used by scientists to work with data do not commonly appear in the science teachers’ class? Sample In the study, 15 practicing scientists and 11 science teachers each participated in a one-on-one interview; and 40 practicing scientists and 175 science teachers each completed a survey. Design and methods We first developed an initial model of working with data based on relevant literature. Next, we conducted a two-stage sequential study. At the exploration stage, we interviewed 15 practicing scientists and 11 science teachers and used the interview data to revise the initial model. At the investigation stage, we conducted surveys with 40 practicing scientists and 175 science teachers. Based on the survey data, we revised and finalized the model. Results The study generated an empirically grounded model that contains five aspects of working with scientific data: purposes of data analysis, planning data collection, organizing and reducing data, representing data, and interpreting analysis results. For each aspect, we identified the strategies used by scientists and investigated whether and how those strategies were taught in science classrooms. Conclusion The results provide a foundation for future research on whether and how the new aspects of working with data can be taught in K-12 science classrooms.","PeriodicalId":46656,"journal":{"name":"Research in Science & Technological Education","volume":"41 1","pages":"306 - 325"},"PeriodicalIF":1.6,"publicationDate":"2021-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/02635143.2021.1902977","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47227180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Purpose This study aims to examine the effects of traditional methods, STEM, and STEAM-based activities on primary school fourth-grade students’ environmental awareness. Besides, the extent to which an aesthetic view predicts environmental awareness was also examined. Sample In the study, practices were carried out on six fourth grade classes located in the state primary schools in Başakşehir district of Istanbul province, which were selected using the random cluster sampling method. Design and methods In the study, a quasi-experimental design with a pretest-posttest control group was used. At the end of the applications, the Environmental Awareness Scale and the Aesthetic View Scale developed by the researchers were applied to the students. As a result of the research, it has been observed that STEM and STEAM-based applications are effective in gaining both environmental awareness and aesthetic perspective, but the traditional method is effective in gaining environmental awareness, but not in gaining an aesthetic view. Results According to ANOVA results to determine which application is more effective in gaining environmental awareness and aesthetic perspective, STEM applications are more effective than traditional applications, and STEAM applications are more effective than both traditional and STEM applications. In the regression analysis, it was seen that the aesthetic view explained 22% of the variation in environmental awareness. Conclusions According to the results of the study, conveying only environmental knowledge to the students in environmental education may be insufficient to reach the intended goal. To raise environmentally sensitive students, it can be said that in environmental education, attention should be paid to gaining affective behaviours and giving students an aesthetic view and cognitive behaviour.","PeriodicalId":46656,"journal":{"name":"Research in Science & Technological Education","volume":"41 1","pages":"326 - 342"},"PeriodicalIF":1.6,"publicationDate":"2021-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/02635143.2021.1908248","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44898252","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Teacher-led questions, cognitive demands and patterns of interaction were analysed for the discourse side of the study. The students’ argumentation quality was explored for the cognition side of the study. Methods Participants were an elementary science teacher and 19 seventh grade students. Socio-cultural discourse analysis was conducted in two phases: systematic observation (coding and counting) and episode analysis (contextual in-depth exploration). Findings The student-led argument quality was found to be reduced due to close-ended triadic dialogues when the teacher overtly displayed follow-up evaluations and follow-up explanations. The argument quality was fostered considerably when the teacher staged timely and relevant follow-up questions, since more dialogic space on the side of the students had been created. The students’ argumentations were observed at the highest levels when the teacher used low (e.g. understand) and high (e.g. analyse and evaluate) cognitively demanding questions together. These findings were also supported by the episode analysis, which aimed at representing the discursive-contextual compositions of the in-class implementations. The results showed that discourse (questions’ cognitive demands and patterns of interaction) and cognition (students’ argumentation quality) were found to be associated.

Purpose: The study seeks to identify factors associated with Cambodian university freshmen’s choice of STEM major and how significant associations differ by gender and university location. Sample: The study draws on primary data collected from a survey of 2,016 freshmen at 15 universities across Cambodia. Design and method: Binary logistic regression was applied to detect correlates of major choice (dichotomized into STEM major and non-STEM major). Results: Students who choose a STEM major are likely to be male, have clearly prioritized the major since high school, have high self-efficacy in the chosen major, want a career in STEM, enrol at a Phnom Penh-based university, excel at mathematics at high school, excel at science at high school, have no job while studying, and value the importance of science and technology to society. When moderated by gender and university location, only excellence in mathematics, excellence in science, and STEM career prospects remained significantly associated with STEM major choice.
