BANGLADESHI SCIENCE TEACHERS’ PERSPECTIVES OF SCIENTIFIC LITERACY AND TEACHING PRACTICES

In line with a current global trend, junior secondary science education in Bangladesh aims to provide science education for all students to enable them to use their science learning in everyday life. This aim is consistent with the call for scientific literacy, which argues for engaging students with science in everyday life. This paper illustrates Bangladeshi science teachers’ perspectives of scientific literacy along with their views on teaching practices. Participating teachers held a range of perspectives of scientific literacy, including some naive perspectives. The paper also reports that whilst teachers’ verbalised practices in relation to their emphasis on engaging students with science in everyday life follows the emphases as required in teaching for promoting scientific literacy, their assessment practices may not be useful to promote it. The discussion explores the meaning of these findings and provides implications for school science educational practice in Bangladesh.     

Upper Secondary Teachers' Knowledge for Teaching Chemical Bonding Models

Researchers have shown a growing interest in science teachers’ professional knowledge in recent decades. The article focuses on how chemistry teachers impart chemical bonding, one of the most important topics covered in upper secondary school chemistry courses. Chemical bonding is primarily taught using models, which are key for understanding science. However, many studies have determined that the use of models in science education can contribute to students’ difficulties understanding the topic, and that students generally find chemical bonding a challenging topic. The aim of this study is to investigate teachers’ knowledge of teaching chemical bonding. The study focuses on three essential components of pedagogical content knowledge (PCK): (1) the students’ understanding, (2) representations, and (3) instructional strategies. We analyzed lesson plans about chemical bonding generated by 10 chemistry teachers with whom we also conducted semi-structured interviews about their teaching. Our results revealed that the teachers were generally unaware of how the representations of models they used affected student comprehension. The teachers had trouble specifying students’ difficulties in understanding. Moreover, most of the instructional strategies described were generic and insufficient for promoting student understanding. Additionally, the teachers’ rationale for choosing a specific representation or activity was seldom directed at addressing students’ understanding. Our results indicate that both PCK components require improvement, and suggest that the two components should be connected. Implications for the professional development of pre-service and in-service teachers are discussed.     

Science Engagement and Literacy: A Retrospective Analysis for Indigenous and Non-Indigenous Students in Aotearoa New Zealand and Australia

Previous research has underlined the importance of school students’ engagement in science (including students’ attitudes, interests and self beliefs). Engagement in science is important as a correlate of scientific literacy and attainment, and as an educational outcome in its own right. Students positively engaged with science are more likely to pursue science related careers, and to support science related policies and initiatives. This retrospective, secondary analysis of PISA 2006 national data for Aotearoa New Zealand and Australia examines and compares the factors associated with science literacy and with science engagement for indigenous and non-indigenous 15 year old students. Using a four step hierarchical regression model, our secondary analyses showed consistent patterns of influence on engagement in science for both indigenous and non-indigenous students in Aotearoa and Australia. Variations in students’ interest, enjoyment, personal and general valuing, self-efficacy, and self concept in science were most strongly associated with the extent to which students engaged in science activities outside of school. In contrast, socioeconomic status, time spent on science lessons and study, and the character of science teaching experienced by students in their schools were the factors most explanatory of variations in science literacy. Yet, the factors that explained variation in science literacy had only quite weak associations with the suite of variables comprising engagement in science. We discuss the implications of these findings for science educators and researchers interested in enhancing students’ engagement with science, and committed to contributing positively to closing the persistent gap in educational outcomes between indigenous and non-indigenous peoples.     

Perceptions,challenges and coping strategies of science teachers in teaching socioscientific issues: A systematic review

Science education in recent years has increasingly emphasized the connections between knowledge and matters of social importance. Socioscientific issues (SSIs)—complex, often controversial issues linked to the development of science and technology—are widely recognized as a valuable arena for the school curriculum to foster students’ scientific literacy. This paper reviews the research literature on how science teachers teach socioscientific issues with 25 empirical studies published between 2004 and 2019. The results show that teachers generally hold a partially informed understanding of SSI-based teaching. Multifarious challenges facing teachers in teaching SSIs are mainly at the teacher, student, and policy levels. However, our findings suggest that teachers lack explicit strategies to cope with these challenges and that SSI-based teaching should not rely on individual teachers alone. We argue for more support for teachers to improve the quality of their implementation of SSIs. This review has implications for education policymakers, teacher educators, school leaders, and teachers to respond to the challenges facing teachers in teaching SSIs collaboratively. Potential directions for further research are also discussed.

The Efficacy of Inquiry-Based Instruction in Science: a Comparative Analysis of Six Countries Using PISA 2015

This study is a comparative analysis of 15-year-old students’ scientific literacy, and its association with the instructional strategies that students experience, across six OECD countries that participated in PISA 2015. Across the six countries, the study investigates the efficacy of inquiry-based instruction in science in contrast with two other instructional approaches to teaching secondary science: adaptive and teacher-directed teaching. The analysis shows that students who reported experiencing high frequencies of inquiry strategies in their classrooms consistently evidenced lower levels of scientific literacy across the six countries. Benchmark analysis also showed, common to all six countries, a strongly positive association between the frequency of teacher-directed and adaptive teaching strategies and students’ scientific literacy. Additionally, the study disaggregates PISA’s composite variable representing inquiry-based instruction and shows that different components of inquiry are differentially associated with students’ scientific literacy. We discuss the implications of these analyses for science teacher educators, science teachers, and educational policy makers. In doing so, we add nuance to our understanding of the efficacy of inquiry-based instruction in science, suggesting that some components, as conceptualised and assessed in PISA, seem to suggest greater attention and use, and others more moderated use.

     

Bridging the Gap? A Comparative,Retrospective Analysis of Science Literacy and Interest in Science for Indigenous and Non‐Indigenous Australian Students

Previous research has shown that indigenous students in Australia do not enjoy equal educational outcomes with other Australians. This secondary analysis of PISA 2006 confirmed that this continues to be the case in science literacy for secondary students. However, the analysis also revealed that indigenous Australian students held interest in science equal to that of their non‐indigenous peers, and that observed variations in science literacy performance were most strongly explained by variations in reading literacy. These findings hold important implications for teachers, teacher educators, policy‐makers, and researchers. Firstly, acknowledging and publicly valuing indigenous Australian science knowledge through rethinking school science curriculum seems an important approach to engaging indigenous students and improving their literacy in science. Secondly, appropriate professional learning for practising teachers and the incorporation of indigenous knowing in science methods training in teacher preparation seems warranted. Additionally, we offer a number of questions for further reflection and research that would benefit our understanding of ways forward in closing the science literacy gap for indigenous students. Whilst this research remains firmly situated within the Australian educational context, we at the same time believe that the findings and implications offered here hold value for science education practitioners and researchers in other countries with similar populations striving to achieve science literacy for all.     

Engaging youth in public lands monitoring: opportunities for enhancing ecological literacy and environmental stewardship

Abstract

The US Forest Service has a long history of youth conservation education. We investigated U.S. Forest Service citizen science programs that involve secondary school students in field collection of monitoring data to understand (1) how the programs integrated science and environmental education and (2) whether these programs advance ecological literacy and environmental stewardship. We conducted semi-structured interviews with the program leads, teachers, and students. Program leads and students said programs produced reliable data and met monitoring and other U.S. Forest Service stewardship objectives. Although these programs varied in design and objectives, our findings suggest these programs were incorporating both science and environmental education, and there is some indication they are creating ecological literacy among participants. Students exhibited environmental stewardship to some degree as a result of all programs, but the extent of this is tied to programs’ objectives and design.     

Teaching for Scientific Literacy? An Examination of Instructional Practices in Secondary Schools in Barbados

This study examined the extent to which the instructional practices of science teachers in Barbados are congruent with best practices for teaching for scientific literacy. Additionally, through observation of practice, it sought to determine the teachers’ demonstrated role in the classroom, their demonstration of learning through discourse, learning goals and the nature of classroom activities. Five hundred nineteen students from 12 of the 23 secondary schools on the island and 15 teachers across 8 schools participated in the study. Data were collected by means of a questionnaire, an observational schedule and field notes. It was found that while problem-solving and questioning were mainly used in the classroom, the use of experiments was among the least popular teaching strategies. Additionally, results showed that teachers’ display of the knowledge of the characteristics of scientific literacy was unsatisfactory. Generally, the findings indicate a gap between teaching for scientific literacy as expressed in the literature and current instructional practices in secondary science classrooms in Barbados.     

First Experiences with Reading Primary Literature by Undergraduate Life Science Students

Learning to read and understand research articles (primary literature) is an important step in the enculturation of higher education students into the scientific community. We presume, based on ideas from the field of genre analysis, that it is important for the development of reading skills to become conscious of the rhetorical structures in research articles. So, we determined how well science students are able to identify 2 important elements of this rhetorical structure: conclusions and grounds. First-year undergraduate life science students who followed a course called ‘Biomedical Research’ made assignments in which they had to identify these 2 elements. We analysed the answers of 20 students in detail and compared their answers with 2 expert readers. Furthermore, we conducted task-based interviews with 4 students to gain more insight into their reading strategies and to determine how they identify conclusions and grounds. Our results show that students and experts defined conclusions and grounds in different ways. Students and experts agreed on the most important conclusion of the articles. However, students identified a wide range of sentences which were not seen as conclusions by the experts. The grounds students mentioned mostly matched their conclusions. Students sometimes failed to mention important grounds for a particular conclusion. In conclusion, our study shows the differences between student and expert readers of primary literature. Based on our results, we formulated criteria for the design of a teaching strategy that aims to improve students' skills for reading primary literature.     

Lecturers’ text competencies and guidance towards academic literacy

Embedding academic literacy into the curriculum and regular subject teaching has received little attention in Norwegian higher education (HE). The present article, drawing on the findings of two studies carried out in 2013/14, seeks to amend this. The first study, an action research study, exposes how lecturers in one of the faculties at Oslo and Akershus University College perceive their role in teaching and guiding students’ discipline-specific literacy, in particular academic writing. Collaborating with the faculty in a joint action research project, we seek to empower the lecturers, and develop pedagogical methods that are suitable for academic literacy teaching and guidance, and thereby make a change in the institution. The second study analyzes the academic literacy skills and knowledge of new students. We follow students in their final semester in upper secondary school, and identify how they are prepared for academic literacy in HE. Together, the studies reveal that despite the students’ preparation for higher studies, they are not fully qualified for meeting the demands of academic literacy. When entering HE, the students are still in need of guidance to establish textual meta-perspectives and to develop relevant disciplinary literacy practices. However, the lecturers are neither fully qualified for nor willing to include this topic in their content teaching.     

Introducing Pre-university Students to Primary Scientific Literature Through Argumentation Analysis

Primary scientific literature is one of the most important means of communication in science, written for peers in the scientific community. Primary literature provides an authentic context for showing students how scientists support their claims. Several teaching strategies have been proposed using (adapted) scientific publications, some for secondary education, but none of these strategies focused specifically on scientific argumentation. The purpose of this study is to evaluate a strategy for teaching pre-university students to read unadapted primary scientific literature, translated into students’ native language, based on a new argumentation analysis framework. This framework encompasses seven types of argumentative elements: motive, objective, main conclusion, implication, support, counterargument and refutation. During the intervention, students studied two research articles. We monitored students’ reading comprehension and their opinion on the articles and activities. After the intervention, we measured students’ ability to identify the argumentative elements in a third unadapted and translated research article. The presented framework enabled students to analyse the article by identifying the motive, objective, main conclusion and implication and part of the supports. Students stated that they found these activities useful. Most students understood the text on paragraph level and were able to read the article with some help for its vocabulary. We suggest that primary scientific literature has the potential to show students important aspects of the scientific process and to learn scientific vocabulary in an authentic context.     

Science Teaching and Learning in Australian Schools: Results of a National Study

This paper reports on a large scale study that investigated the quality of teaching and learning in science in Australian schools. Its purposes were first, to describe ideal practice in the teaching and learning of school science; second, to describe the nature of teaching and learning of science in Australian schools; and third, to make recommendations to move the actual closer to the ideal.Fundamental to the research was the belief that scientific literacy is a high priority for all citizens, helping them to be interested in, and understand the world around them, to be sceptical and questioning of claims made by others about scientific matters, to be able to identify questions, investigate and draw evidence-based conclusions, and to make informed decisions about the environment and their own health and well-being.Based on national and international reports and research literature, and substantial new data collected from teachers, students and other Australian stakeholders in science education, the ideal picture was described in nine themes relating to the curriculum, teaching and learning strategies, professionalism of teachers and their career path, resources and facilities, and the value of science and science education to the community. The actual picture was one of great variability, but overall, it was bleak. The actual curriculum implemented in most schools differs from the intended curriculum, which is focused on developing scientific literacy and helping students progress towards achieving the stated outcomes. Science in primary schools is generally student-centred and activity-based. When students move to high school, many experience disappointment, because the science they are taught is neither relevant nor engaging and does not connect with their interests and experiences. Disenchantment with science is reflected in the decline in science subjects taken by students in upper secondary school. Many science teachers feel undervalued, under-resourced and overloaded with non-teaching duties.The recommendations developed to improve the status and quality of science education were underlain by five fundamental premises: the purpose of science education is to develop scientific literacy, the focus for change is closing the gap between the actual and ideal, teachers are the key to change, change takes time and resources, and collaboration is essential for quality science education. Preliminary recommendations were prepared and scrutinised by members of a government-appointed Steering Committee for the project, critical friends, and teacher focus groups. Recommendations concerning awareness, teachers, resources, assessment, and national collaboration were developed incorporating feedback from the process described, each including a range of suggested actions for implementation that were feasible in the Australian context. If Commonwealth and State governments choose to act on these recommendations, the gap between the actual picture of science teaching and learning in Australia and the ideal will be significantly reduced.     

Science and Technology Education in the STES Context in Primary Schools: What Should It Take?

Striving for sustainability requires a paradigm shift in conceptualization, thinking, research and education, particularly concerning the science-technology-environment-society (STES) interfaces. Consequently, ‘STES literacy’ requires the development of students’ question asking, critical, evaluative system thinking, decision making and problem solving capabilities, in this context, via innovative implementable higher-order cognitive skills (HOCS)-promoting teaching, assessment and learning strategies. The corresponding paradigms shift in science and technology education, such as from algorithmic teaching to HOCS-promoting learning is unavoidable, since it reflects the social pressure, worldwide, towards more accountable socially- and environmentally-responsible sustainable development. Since most of the STES- and, recently STEM (science-technology-engineering-mathematics)-related research in science education has been focused on secondary and tertiary education, it is vital to demonstrate the relevance of this multifaceted research to the science and technology teaching in primary schools. Our longitudinal STES education-related research and curriculum development point to the very little contribution, if any, of the traditional science teaching to “know”, to the development of students’ HOCS capabilities. On the other hand, there appears to be a ‘general agreement’, that the contemporary dominant lower-order cognitive skills (LOCS) teaching and assessment strategies applied in science and technology education are, in fact, restraining the natural curiosity and creativity of primary school (and younger?) pupils/children. Since creative thinking as well as evaluative system thinking, decision making, problem solving and … transfer constitute an integral part of the HOCS conceptual framework, the appropriateness of “HOCS promoting” teaching, and the relevance of science and technology, to elementary education in the STES context, is apparent. Therefore, our overriding guiding purpose was to provide any evidence-based research to the vital LOCS-to-HOCS paradigm shift in STES education. The findings of, and conclusions derived from our longitudinal research on HOCS development within STES-oriented and traditional education, suggest that both—science and technology education (STE) and STES education—are relevant to primary school education. Based on this, what it should take to insure success in this context, is thoroughly discussed.

Genetics Literacy: Insights From Science Teachers’ Knowledge,Attitude, and Teaching Perceptions

Teachers have a crucial role to play in raising future generations of citizens who are aware of issues in genetics literacy such as gene therapy, cloning, and stem cell research. Teachers’ teaching practices are influenced by their knowledge in genetics literacy and their attitudes towards different issues. Accordingly, this study explored the relationships among middle school science teachers’ background characteristics (gender, teaching experience, self-perceived interest in and self-perceived knowledge of genetics), their genetics literacy levels, their attitudes towards various issues in genetics literacy, and their perceptions of teaching issues in genetics literacy. Data were collected from 435 Turkish middle school science teachers by completing the Genetics Literacy Assessment Inventory, the scale for attitudes towards issues in genetics literacy and perceptions of teaching issues in genetics literacy. The results of canonical correlation analysis suggested that being female, having a high level of interest in genetics, and perceiving oneself as knowledgeable in genetics were associated with higher levels of knowledge in genetics literacy and holding favorable general attitudes. These teachers believed in the necessity of introducing genetics literacy and held higher self-efficacy teaching beliefs regarding the teaching of issues in genetics literacy in their classes. However, they tended to emphasize more impeding factors as well as hold unfavorable attitudes towards gene therapy and gene therapy applications, implying that their attitudes were context dependent.     

Science education reform in Confucian learning cultures: teachers’ perspectives on policy and practice in Taiwan

This empirical study investigates secondary science teachers’ perspectives on science education reform in Taiwan and reflects how these teachers have been negotiating constructivist and learner-centered pedagogical approaches in contemporary science education. It also explores the challenges that teachers encounter while shifting their pedagogical focus from traditional approaches to teaching science to an active engagement in students’ learning. Multiple sources of qualitative data were obtained, including individual interviews with science teachers and teachers’ reflective journals about Confucianism in relation to their educational philosophies. Thematic analysis and constant comparative method were used to analyze the data. The findings revealed that Confucian traditions play a significant role in shaping educational practices in Taiwan and profoundly influence teachers’ epistemological beliefs and their actual classroom practice. Indeed, science teachers’ perspectives on Confucian learning traditions played a key role in supporting or obstructing their pedagogical commitments to inquiry-based and learner-centered approaches. This study draws on the literature concerning teachers’ professional struggles and identity construction during educational reform. Specifically, we explore the ways in which teachers respond to educational changes and negotiate their professional identities. We employed various theories of identity construction to understand teachers’ struggles and challenges while wrestling with competing traditional and reform-based pedagogical approaches. Attending to these struggles and the ways in which they inform the development of a teacher’s professional identity is vital for sustaining current and future educational reform in Taiwan as well as in other Eastern cultures. These findings have important implications for teachers’ professional development programs in East Asian cultures.     

Are secondary school graduates prepared for the studies of natural sciences? – evaluation and analysis of the result of scientific literacy levels achieved by secondary school graduates

ABSTRACT

Background: In Slovakia, no relevant information is available about the scientific literacy levels achieved by secondary school students.

Purpose: The objective of the research was to identify the levels of scientific literacy among students in the last year of grammar school and examine to what extent this determined the subject chosen for a school-leaving exam, which is related to a student’s personal preferences, as well as to the student’s profile and preparation for university education.

Sample: The research sample consisted of 221 students from 17 grammar schools located in various regions of Slovakia.

Design and methods: To identify the level of scientific literacy, we applied the Test of Scientific Literacy Skills.

Results: The students achieved the lowest success rate in the skill focused on the identification of the research design elements and its strengths and weaknesses. A comparably low success rate was also observed in the skill focused on the justification of the conclusions based on quantitative data. Other difficulties were identified in the field of understanding the basics of statistics, thus indicating an insufficient level of mathematical literacy of the students in the abovementioned field. By contrast, the highest success rate was achieved in the skill focused on the correct application of the scientific results for social purposes.

Conclusions: At the end of secondary school studies, the scientific literacy among Slovak students is at the average level. No differences were observed in terms of gender. In terms of the subjects chosen by the students for their school-leaving exams, we observed that those students who took a school-leaving exam in Biology or Chemistry achieved significantly better results in the test. By contrast, the students who reported on Geography and Civics as the subject of their school-leaving exam achieved significantly worse results in the test.
