Urban High School Students’ Critical Science Agency: Conceptual Understandings and Environmental Actions Around Climate Change

This study investigates how the enactment of a climate change curriculum supports students’ development of critical science agency, which includes students developing deep understandings of science concepts and the ability to take action at the individual and community levels. We examined the impact of a four to six week urban ecology curriculum on students from three different urban high schools in the USA. Data collection included pre and posttest written assessments from all students (n = 75) and pre and post interviews from focal students (n = 22) to examine how students’ conceptual understandings, beliefs and environmental actions changed. Our analyses showed that at the beginning of the curriculum, the majority of students believed that climate change was occurring; yet, they had limited conceptual understandings about climate change and were engaged in limited environmental actions. By the end of the curriculum, students had a significant increase in their understanding of climate change and the majority of students reported they were now engaged in actions to limit their personal impact on climate change. These findings suggest that believing a scientific theory (e.g. climate change) is not sufficient for critical science agency; rather, conceptual understandings and understandings of personal actions impact students’ choices. We recommend that future climate change curriculum focus on supporting students’ development of critical science agency by addressing common student misconceptions and by focusing on how students’ actions can have significant impacts on the environment.     

Exploring environmental identity and behavioral change in an Environmental Science course

This ethnographic study at a public high school in the Northeastern United States investigates the process of change in students’ environmental identity and proenvironmental behaviors during an Environmental Science course. The study explores how sociocultural factors, such as students’ background, social interactions, and classroom structures, impact the environmental identity and behavior of students. In this investigation, the identity theory of emotion of Stryker (2004) from the field of sociology is utilized in the interpretation of students’ reactions to classroom experiences as they proceed through the Environmental Science course. The participants in this study are an Environmental Science teacher and the 10–12th grade students in her Environmental Science elective course. The researcher collected data for a period of six months, attending class on a daily basis. Data was collected through participant observation, videotaping, interviews, and cogenerative dialogues. The results of this study inform science educators by illuminating important elements, such as students’ emotional responses to activities in class, conflicting elements of students’ identities, and students’ openness and willingness to critically reflect upon new information, which contribute to whether a student is likely to change their views towards the environment and pro-environmental behaviors.     

The impact of integrated environmental studies programs: are students motivated to act pro-environmentally?

In Canada, there exists a noteworthy educational initiative referred to as Environmental Studies Programs (ESPs). These secondary school programs are interdisciplinary, helping to link subject matter and encouraging student responsibility. The results of two case studies of Ontario ESPs that analyze the impact of ESP participation on students’ attitudes to, and relationships with, the environment and the extent to which program participation informs domestic pro-environmental behaviors and/or emancipatory social and environmental actions are presented. The results from the focus group sessions indicate that students believe that they can effect environmental change but that they struggle with ways to meaningfully enact that change in light of ‘real world’ constraints.     

Investigating Urban Eighth-Grade Students’ Knowledge of Energy Resources

This study investigated urban eighth-grade students’ knowledge of energy resources and associated issues including energy acquisition, energy generation, storage and transport, and energy consumption and conservation. A 39 multiple-choice-item energy resources knowledge assessment was completed by 1043 eighth-grade students in urban schools in two cities in Pennsylvania, USA. Mean scores for the entire assessment measure indicated low conceptual energy knowledge of the eighth-grade students. Subscale means revealed that student understandings of energy resource acquisition, energy generation, storage and transport, and energy consumption and conservation are not satisfactory. Distractor analysis identified many misunderstandings that eighth-grade students hold with regard to energy resources. Findings revealed that students did not have a sound knowledge and understanding of basic scientific energy resources facts, issues related to energy sources and resources, general trends in the US energy resource supply and use, and the impact energy resource development and use can have on society and the environment. Implications for teacher enactment of energy resources curriculum activities are discussed.     

Marine environmental protection knowledge,attitudes, behaviors,and curricular involvement of Taiwanese primary school students in senior grades

In recent years, rapid changes in the Earth's climate and environment have influenced our lives greatly. The ocean occupies 70% of the Earth's surface and is intimately related to the regulation of climate, fostering of life, and also to social economy, as well as sports and leisure. Students in the senior years of primary education are in a phase of developing value systems. Concurrently, these students are also constantly using the Earth's resources. More importantly, they will play leading roles in the next generation. From the perspective of education, the learning status of student's cognition, attitudes, and behaviors regarding protection of the marine environment must be understood more clearly to avoid future mismanagement of marine environmental problems on the part of these students. Hence, this study uses correlative, regressive, and path statistical analysis to examine data collected from questionnaires. Results show that student knowledge of and attitudes toward marine environmental protection do not have significant influences on behaviors; however, student's marine environmental protection knowledge, attitudes, and behaviors are all within the medium to high range. Because of relatively low student curricular involvement, and because involvement has no correlation with knowledge performance, this study infers that school curricula are not the main sources of student information and attitudes regarding marine environmental protection. Rather, building student attitudes toward marine environmental protection by increasing their involvement in field trips indirectly influences behaviors that are protective of the marine environment. Such an approach is comparatively more effective and can serve as a reference for modifying the implementation methods of marine protection curricula.     

Middle and high school students’ conceptions of climate change mitigation and adaptation strategies

Both scientists and policy-makers emphasize the importance of education for influencing pro-environmental behavior and minimizing the effects of climate change on biological and physical systems. Education has the potential to impact students’ system knowledge – their understanding of the variables that affect the climate system – and action knowledge – their understanding of behaviors that can impact the system. Research on climate change education has largely focused on system and action knowledge that address mitigation while overlooking equally necessary adaptive responses. This study used a pre/post-test format to identify aspects of middle and high school students’ climate system knowledge and action knowledge of both mitigation of and adaptation to climate change. Results indicate that adolescents currently conflate climate change mitigation strategies with unrelated environmental problems far less than in previous surveys. However, students demonstrated limited understanding of adaptive responses to climate change. After engaging in an instructional unit on climate change, students expressed stronger system and action knowledge, but significant misconceptions remained that conflated mitigation of and adaptation to climate change.     

Teaching primary science: emotions, identity and the use of practical activities

This paper uses cultural historical activity theory to examine the interactions between the choices primary teachers make in the use of practical activities in their teaching of science and the purposes they attribute to these; their emotions, background and beliefs; and the construction of their identities as teachers of science. It draws on four case studies of science lessons taught over a term by four exemplary teachers of primary science. The data collected includes video recordings of science lessons, interviews with each teacher and some of their students, student work, teachers?? planning documents and observation notes. In this paper, we examine the reflexive relationship between emotion and identity, and the teachers?? objectives for their students?? learning; the purposes (scientific and social) the teachers attributed to practical activities; and the ways in which the teachers incorporated practical activities into their lessons. The findings suggest that it is not enough to address content knowledge, pedagogy and pedagogical content knowledge in teacher education, but that efforts also need to be made to influence prospective primary teachers?? identities as scientific thinkers and their emotional commitment to their students?? learning of science.     

��Good�� mathematics teaching for students of color and those in poverty: the importance of relational interactions within instruction

In considering ??good teaching?? in mathematics, scholars usually refer to teacher knowledge and instructional practices that promote understanding. However, researchers have found that these two elements of instruction are often not as prevalent in urban contexts, a space where high percentages of students of color and the poor are educated. Additionally, recent work calls for understanding other classroom mechanisms that impact the mathematics learning of students of color. Using video, field notes, and an interview, this research examines a case study of one urban classroom of Latino and African American students. Their teacher engages them in substantive mathematics and reform-minded pedagogical strategies, but a number of relational interactions raise issues of how these micro-interactions can mediate access to mathematics. The study found four dimensions in which relational interactions mediated access to mathematics: addressing behavior, framing mathematics ability, acknowledging student contributions, and attending to culture and language. The paper ends with raising questions for future research and calling for a broader framing of instruction that incorporates relational dimensions of the classroom.     

Planning for Reform-Based Science: Case Studies of Two Urban Elementary Teachers

The intent of national efforts to frame science education standards is to promote students’ development of scientific practices and conceptual understanding for their future role as scientifically literate citizens (NRC 2012). A guiding principle of science education reform is that all students receive equitable opportunities to engage in rigorous science learning. Yet, implementation of science education reform depends on teachers’ instructional decisions. In urban schools serving students primarily from poor, diverse communities, teachers typically face obstacles in providing reform-based science due to limited resources and accountability pressures, as well as a culture of teacher-directed pedagogy, and deficit views of students. The purpose of this qualitative research was to study two white, fourth grade teachers from high-poverty urban schools, who were identified as transforming their science teaching and to investigate how their beliefs, knowledge bases, and resources shaped their planning for reform-based science. Using the Shavelson and Stern’s decision model for teacher planning to analyze evidence gathered from interviews, documents, planning meetings, and lesson observations, the findings indicated their planning for scientific practices was influenced by the type and extent of professional development each received, each teacher’s beliefs about their students and their background, and the mission and learning environment each teacher envisioned for the reform to serve their students. The results provided specific insights into factors that impacted their planning in high-poverty urban schools and indicated considerations for those in similar contexts to promote teachers’ planning for equitable science learning opportunities by all students.     

Influence of an Environmental Studies Course on Attitudes of Undergraduates at an Engineering University

Studies suggest that at engineering universities, where the percentage of males and engineering majors is high, pro-environmental attitudes are likely to be weak and may not change. The 15-item New Ecological Paradigm (NEP) scale was used to measure differences in student attitudes before and after an environmental studies course. Results revealed students held more pro-environmental attitudes about the validity of the ecological crisis, the existence of resource constraints, and the delicacy of nature's balance after the course. Students did not shift their views regarding the domination of humans over the environment or their belief in human ingenuity to overcome resource limits. Engineering majors showed weaker endorsement of the NEP compared to non-engineering majors, but the increase in their endorsement after the course was statistically significant.     

Academic self‐beliefs and prior knowledge as predictors of student achievement in Mathematics: a structural model

The aim of this study was to explore the relationships between prior knowledge, academic self‐beliefs, and previous study success in predicting the achievement of 139 students on a university mathematics course. Structural equation modelling was used to explore the interplay of these variables in predicting student achievement. The results revealed that domain‐specific prior knowledge was the strongest predictor of student achievement over and above other variables included in the model and, together with previous study success, explained 55% of the variance. Academic self‐beliefs strongly correlated with previous study success and had a strong direct influence on prior knowledge test performance. However, self‐beliefs predicted student achievement only indirectly via prior knowledge. The results imply that both prior knowledge and self‐beliefs should be taken into account when considering instructional support issues, because they can provide valuable insights about the future performance of the students.     

Undergraduate Understanding of Climate Change: The Influences of College Major and Environmental Group Membership on Survey Knowledge Scores

A survey covering the scientific and social aspects of climate change was administered to examine U.S. undergraduate student mental models, and compare knowledge between groups based on major and environmental group membership. A Knowledge Score (scale 0–35, mean score = 17.84) was generated for respondents at two, central East Coast, U.S. universities (n = 465). Elements of student mental models examined include environmental issue confusion, skepticism, and self-reported understanding. This study finds that students frequently confuse climate change with other environmental issues, and that a substantial majority of students do not have an understanding of climate change that closely matches the scientific model. These misconceptions extend to their understanding of mitigation actions. Environmental group membership is shown to be a greater determinant of climate change knowledge than enrollment in a science major.     

Disconnections Between Teacher Expectations and Student Confidence in Bioethics

This study examines how student practice of scientific argumentation using socioscientific bioethics issues affects both teacher expectations of students’ general performance and student confidence in their own work. When teachers use bioethical issues in the classroom students can gain not only biology content knowledge but also important decision-making skills. Learning bioethics through scientific argumentation gives students opportunities to express their ideas, formulate educated opinions and value others’ viewpoints. Research has shown that science teachers’ expectations of student success and knowledge directly influence student achievement and confidence levels. Our study analyzes pre-course and post-course surveys completed by students enrolled in a university level bioethics course (n = 111) and by faculty in the College of Biology and Agriculture faculty (n = 34) based on their perceptions of student confidence. Additionally, student data were collected from classroom observations and interviews. Data analysis showed a disconnect between faculty and students perceptions of confidence for both knowledge and the use of science argumentation. Student reports of their confidence levels regarding various bioethical issues were higher than faculty reports. A further disconnect showed up between students’ preferred learning styles and the general faculty’s common teaching methods; students learned more by practicing scientific argumentation than listening to traditional lectures. Students who completed a bioethics course that included practice in scientific argumentation, significantly increased their confidence levels. This study suggests that professors’ expectations and teaching styles influence student confidence levels in both knowledge and scientific argumentation.     

Role of Significant Life Experiences in Building Environmental Knowledge and Behavior Among Middle School Students

Significant life experience research suggests that the presence of role models, time outdoors, and nature-related media foster pro-environmental behavior, but most research is qualitative. Based on a random sample of middle school students in North Carolina, USA, we found limited positive associations between presence of a role model and time outdoors with behavior and a negative association between watching nature television and environmental knowledge. The strongest predictors of environmental knowledge and behavior were student/teacher ratio and county income levels, respectively. We also found that Native Americans engaged in environmental behaviors more than Caucasians, and that African American and Hispanic students had lower levels of environmental knowledge. Accordingly, life experiences appear less important than promoting small class sizes and addressing challenges associated with lower incomes in schools.     

“Do I Really Hafta?” WebCal,A Look at the Use of LiveMath Software in Web-based Materials that Provide Interactive Engagement in a Collaborative Learning Environment for Differential Calculus

This paper describes the use of a Web-based Computer Algebra System (CAS) called LiveMath in a computer supported collaborative learning environment for Differential Calculus. The instructional design incorporated a Reform Calculus notion of Calculus and a constructivist philosophy of learning. Based on interviews with students, independent observations in the classroom, and observations by the teacher, this paper provides insight for students, instructional designers and classroom educators into the issues raised in this environment. The study was exploratory in nature, concerning itself with testing and revising both the materials and the setting in which they were used. The intent was to discover interaction between characteristics of students and the environment which warrant future study. For example, the use of LiveMath seemed in some cases to cause cognitive overload. In addition, student epistemological beliefs, prior knowledge of symbolic representations of functions and propensity for self-directed learning interacted with the ability of students to use LiveMath inserts to attain conceptual understanding. While students appear to have learned some concepts more deeply, and others more rapidly than anticipated, they reported that they judged that they were working harder than friends in other sections. Further, being in a student centred learning environment was unsettling for both the students and the instructor.     

The Concept of Environmental Education

This exploratory study investigated elementary teachers’ beliefs about, perceived competencies for, and reported use of scientific inquiry to promote students’ learning about environmental issues and for environmental decision making and action. Data were collected through a questionnaire administered to a simple random sample of elementary teachers in and around a Midwestern university community (n = 121, r = 52%). Respondents did not differentiate between inquiry practices that promote student learning about and for the environment. While respondents believed that they should engage in these practices, they were less confident in their ability to do so, and reported spending little time engaging in these practices. Results also suggest, however, that methods courses and professional development can support elementary teachers’ use of inquiry-based teaching about and for the environment.     

Young Children's Exposure to Mathematics: The Child Care Context

Four preschool teachers from two preschool settings were observed to explore the contribution of child care experiences on the development of young children's understanding of mathematics. Teachers were also interviewed regarding their attitudes and beliefs about the importance of early education, children's understanding of mathematics prior to formal schooling, and their role in facilitating mathematical knowledge. Although the programs and teachers differed in terms of program orientation, teaching style, student participation, and interactions with students, the programs did not differ in terms of the amount or content of mathematics presented to children. During the classroom observations that were conducted, very little mathematics was presented in any of the classrooms either directly or indirectly to students. In contrast, teachers said that they believed that mathematics was important and that they engaged in mathematical discussions in their classroom interactions. Discussion of the lack of math presented in the classroom and the discrepancy of teachers' beliefs and teaching behaviors are discussed.
