The Effect of Nature of Science Metacognitive Prompts on Science Students’ Content and Nature of Science Knowledge,Metacognition, and Self‐Regulatory Efficacy

The purpose of the present explanatory mixed‐method design is to examine the effectiveness of a developmental intervention, Embedded Metacognitive Prompts based on Nature of Science (EMPNOS) to teach the nature of science using metacognitive prompts embedded in an inquiry unit. Eighty‐three (N = 83) eighth‐grade students from four classrooms were randomly assigned to an experimental and a comparison group. All participants were asked to respond to a number of tests (content and nature of science knowledge) and surveys (metacognition and self‐regulatory efficacy). Participants were also interviewed. It was hypothesized that the experimental group would outperform the comparison group in all measures. Partial support for the hypotheses was found. Specifically, results showed significant gains in content knowledge and nature of science knowledge of the experimental group over the comparison group. Qualitative findings revealed that students in the comparison group reported scientific thinking in similar terms as the scientific method, while the experimental group reported that scientists were creative and had to explain events using evidence, which is more closely aligned to the aspects of the nature of science. EMPNOS may have implications as a useful classroom tool in guiding students to check their thinking for alignment to the nature of science.     

Prospective Elementary Teachers' Knowledge of Teaching Science as Argument: A Case Study

The National Research Council emphasizes the centrality of discourse and practices associated with constructing, evaluating, and using scientific explanations. These expectations increase already daunting challenges for those who teach science at the elementary school level. This study followed a multiparticipant case study approach examining prospective elementary teachers' self‐reports of teaching science as argument. Findings yield that the presence of opportunities for physical experimentation with firsthand data during science instruction helped participants increase their emphasis on evidence‐based explanations. Participants also viewed science talks as essential and fundamental for engaging students in evidence‐based explanations. Finally, participants demonstrated attention to scientific subject matter. These findings are discussed in terms of their implications for teacher education.     

The Influence of Mind Mapping on Eighth Graders’ Science Achievement

This study assessed the influence of using mind maps as a learning tool on eighth graders’ science achievement, whether such influence was mediated by students’ prior scholastic achievement, and the relationship between students’ mind maps and their conceptual understandings. Sixty‐two students enrolled in four intact sections of a grade 8 science classroom were randomly assigned to experimental and comparison conditions. Participants in the experimental group received training in, and constructed, mind maps throughout a science unit. Engagement with mind mapping was counterbalanced with involving the comparison group participants with note summarization to control for time on task as a confounding variable. Otherwise, the intervention was similar for both groups in all respects. A multiple choice test was used to measure student gains across two categories and three levels of achievement. Data analyses indicated that the experimental group participants achieved statistically significant and substantially higher gains than students in the comparison group. The gains were not mediated by participants’ prior scholastic achievement. Analyses also indicated that iconography was not as central to participants’ mind maps as often theorized. Depicting accurate links between central themes and major and minor concepts, and using colors to represent concepts were the major aspects that differentiated the mind maps built by students who achieved higher levels of conceptual understanding.     

Mathematics Anxiety and Preservice Elementary Teachers' Confidence to Teach Mathematics and Science

Sixty‐five preservice elementary teachers' math anxiety levels and confidence levels to teach elementary mathematics and science were measured. The confidence scores of subjects in different math anxiety groups were compared and the relationships between their math anxiety levels and confidence levels to teach mathematics and science were investigated. The results suggest that low math anxious preservice teachers are more confident to teach elementary mathematics and science than are their peers having higher levels of math anxiety. Negative correlations were found between preservice teachers' math anxiety and their confidence scores to teach elementary mathematics (r = ?.638) and between preservice teachers' math anxiety and their confidence scores to teach elementary science (r = ‐.417). Also, personal math and science teaching self‐efficacy scores of participants were found to be correlated at .01 level (r =.549).     

Behind the Masks: Identifying Students' Competencies for Learning Mathematics and Science in Urban Settings

Three mathematics and science educators reexamine and reflect on their teaching within the context of the American Association for the Advancement of Sciences (AAAS) and National Council of Mathematics' call to make math and science education accessible to all. The paper highlights the importance of teachers reflecting on their teaching practices in order to create opportunities for their students especially those in the urban setting. The educators argue that teachers' reflection on their teaching can cause them to recognize and validate their students' ways of knowing as they identify the students' hidden/concealed abilities that are often masked by their behaviors. The educators discuss their experiences and highlight the lessons that they learned about ways to prepare teachers to successfully teach math and science students in urban settings. Culturally responsive pedagogy and cultural competency are critical skills that teachers need to develop in order to teach all children, especially those in the math and science classroom in the urban setting.     

Scientists Taking a Nature of Science Course: Beliefs and Learning Outcomes of Career Switchers

The purpose of the study was to examine what scientists studying to become teachers know about the nature of science (NOS) before, during and after a course focused on NOS. The 16 scientists had an average of 9.7 years of work experience. The course was structured to teach knowledge about the aspects of NOS, demonstrate effective methods of teaching NOS, provide examples of successful attempts at meaningfully incorporating NOS into science content, and give students an opportunity to design and teach their own lessons incorporating NOS. Data sources collected include a prepost test of Views of Science and Education, electronic discussion postings, written class assignment of a clinical interview with an adolescent about NOS, video recordings of teaching, and individual interviews conducted three months after the course. Quantitative and qualitative data indicate that the scientists entered the course with much knowledge regarding the tentativeness of science and the nature of observations. There were significant gains in sophistication of view of NOS with regard to the following aspects of NOS: (a) knowing that variety of scientific methods exist, (b) the role of theories and laws, (c) the use of imagination, and (d) the role of subjectivity and objectivity in science.     

Teaching Science as Science Is Practiced: Opportunities and Limits for Enhancing Preservice Elementary Teachers' Self‐Efficacy for Science and Science Teaching

Science teaching in elementary schools, or the lack thereof, continues to be an area of concern and criticism. Preservice elementary teachers' lack of confidence in teaching science is a major part of this problem. In this mixed‐methods study, we report the impacts of an inquiry‐based science course on preservice elementary teachers' self‐efficacy for science and science teaching, understanding of science, and willingness to teach it in their future careers. Our findings suggest that for some students, the inquiry‐based science course positively influenced their self‐efficacy for science and science teaching. Gains were made in a majority of students' conceptual understanding of science, understanding of the science process and scientific research, and confidence with science and science teaching. The subjects did not experience the course uniformly, however. Rather, there appeared to be two distinct groups, one on a trajectory of improving their outlook on science teaching and one worsening. The results presented here therefore provoke some interesting questions regarding preservice elementary teachers' preparation for science teaching.     

Service Learning Within a Secondary Math and Science Teacher Education Program: Preservice MAT Teachers’ Perspectives

Previous literature suggests that service learning may offer new opportunities to support the development of preservice science and math teachers, but few studies examine service learning beyond isolated teaching events. In this qualitative study, we attempt to improve upon this literature by following Master of Arts in Teaching (MAT) students’ views of their service learning experiences throughout their MAT program and first two years teaching. Data sources included audiotaped individual interviews, focus group field notes, and surveys with seven preservice teachers over a three‐year period. Three major findings emerged from the data analysis. First, participants identified characteristics of service learning teaching events that made them particularly useful, and these included the timing of events, targeted grade level, exposure to high‐needs contexts, and opportunities to practice pedagogical skills. Second, participation in the service learning events improved preservice teachers’ confidence and comfort teaching in high‐needs contexts, but several concerns and deficit perspectives about teaching in high‐needs contexts remained. Third, participants indicated specific ways that the service learning teaching events impacted their readiness to teach in high‐needs contexts. These findings may inform other science and math teacher educators seeking to embed service learning opportunities into their programs.     

Teachers Describe Epistemologies of Science Instruction Through Q Methodology

Creating scientifically literate students is a common goal among educational stakeholders. An understanding of nature of science is an important component of scientific literacy in K‐12 science education. Q methodology was used to investigate the opinions of preservice and in‐service teachers on how they intend to teach or currently teach science. Q methodology is a measurement tool designed to capture personal beliefs. Participants included 40 preservice and in‐service elementary and secondary science teachers who sorted 40 self‐referential statements regarding science instruction. The results identified three epistemologies toward teaching science: A Changing World, My Beliefs, and Tried and True. Participants with the A Changing World epistemology believe evidence is reliable, scientific knowledge is generated in multiple ways, and science changes in light of new evidence. The My Beliefs epistemology reflects that scientific knowledge is subject to change due to embedded bias, science is affected by culture and religion, and evolution should not be taught in the classroom. The Tried and True epistemology views a scientific method as an exact method to prove science, believes experiments are crucial for scientific discoveries, absolute truth exists in scientific knowledge, and society and cultural factors can be eliminated from investigations. Implications for preservice teacher education programs and in‐service teacher professional development are addressed.     

Science as a Learner and as a Teacher: Measuring Science Self‐Efficacy of Elementary Preservice Teachers

Academic science achievement of U.S. students has raised concerns regarding our ability as a nation to compete in a global economy. Additionally, research has shown that many elementary teachers have weak science content backgrounds and had poor/negative experiences as students of science, resulting in a lack of confidence regarding teaching science. However, efforts to increase science self‐efficacy (SE) in preservice teachers can help to combat these issues. This study looked at a sample of preservice elementary teachers engaged in a semester‐long science content course, using Bandura's concept of SE as a conceptual framework. Our quantitative data showed significant increases in science SE on both subscales (personal efficacy and outcome expectancy). Our qualitative data showed that students communicated an increased sense of confidence with regard to the discipline of science. In addition, students reported learning science pedagogy through the instructor's modeling. Combining our findings resulted in several meta‐inferences, one of which showed students growing as both confident learners of science and teachers of science simultaneously. We created a construct new to the literature to describe this phenomenon: “teacher‐learner,” for students are both learning science and learning to teach science simultaneously through the content course experience, resulting in increased science SE.     

Student Perceptions of Interest,Learning, and Engagement from an Informal Traveling Science Museum

Informal Science Education (ISE) programs have been increasing in popularity in recent years. The National Research Council has laid out six strands that ISE programs should try to address, including increasing interest, knowledge, and allowing participants to engage in scientific activities. Past research suggests that informal settings can increase interest in science and may lead to knowledge gains. This study examined the impact of a unique ISE program that resembles a traveling museum and offers small‐scale, interactive experiences. Affective outcomes and self‐reported learning outcomes of the students who participated in the program were examined. In general, students reported increases in science interest and some knowledge gains. Students also reported they thought the program allowed them to engage in science. There were differences in student responses based on grade level, with intermediate elementary students more likely to report greater knowledge gains and more likely to see the educational value of the experience. Interestingly, middle school students were more likely to value the social aspects of the experience, another important aspect of ISE. This study provides some insight into the connections between the different ISE strands of informal science education and offers suggestions for future research.     

Student Interest in Engineering Design‐Based Science

Current reform efforts in science education around the world call on teachers to use integrated approaches to teach science. As a part of such reform efforts in the United States, engineering practices and engineering design have been identified in K–12 science education standards. However, there is relatively little is known about effective ways of teaching science through engineering design. The study explores the approaches or strategies used by a sixth grade science teacher to teach science and engineering in an integrative manner. Classroom observations, teacher interview, and student surveys were used to study the features of engineering integration implemented by the teacher and the changes in student interest in science and engineering by participating in an engineering design‐based science unit. Findings suggest that the teacher explicitly included practices and core ideas from engineering and science; used an engaging, motivating engineering challenge; and provided students with opportunities to be autonomous. Students engaged in the activities in the engineering unit and their interest level slightly increased. The results suggest that the three strategies that the teacher used to teach engineering and science are important foundations of integrated science and engineering education.     

Implementing Coteaching and Cogenerative Dialoguing in Urban Science Education

Over the past 7 years the authors have been involved in the development of a new model for the education of science teachers that has the potential to address teacher education in challenging urban settings characterized by problems such as teacher turnover and retention, low job satisfaction, and contradictions arising from cultural and ethnic diversity. An intensive research program accompanied the development effort; the research results were used as resources in redesigning the evolving model to make it more appropriate for the situations at hand. The science teacher education program at an urban university was built around a yearlong field experience, during which all prospective teachers learned to teach in an urban high school while coteaching, that is, while teaching at the elbow of a mentor teacher or one or more peers. Over this period, a number of different configurations of coteaching and the associated cogenerative dialoguing were tried, tested, and investigated. The paper describes the historical development of the different configurations of the model and the emergent contradictions that led the researchers to enact changes to their approach. The central idea in the development effort was the creation of an environment that (a) best affords the learning of how to teach in urban high schools, (b) decreases teacher isolation, (c) mitigates turnover and retention, and (d) addresses contradictions arising from the cultural and ethnic diversity of students and teachers. Most importantly, this model of teacher education and enhancement simultaneously multiplies the resources and opportunities to support the learning of students.     

Reflective Pathways: Analysis of an Urban Science Teaching Field Experience on Noyce Scholar‐Science Education Awardees' Decisions to Teach Science in a High‐Need New York City School

Awardees of the National Science Foundation's Noyce Scholars funds are required to teach science in high‐need urban or rural school districts upon graduation. The purpose of this research was to analyze the reflective considerations that distinguish preservice Noyce Scholar science education majors committed to teaching in high‐need New York City (NYC) schools from those committed to high‐need rural careers. Essays designed to expose their (n = 22) considerations of teaching in NYC written before, immediately after, and two weeks following a one‐week cultural and science teaching internship experience were coded to reveal distinguishing reflective thought patterns. The results showed that those (16/22) whose final essay showed commitment to NYC teaching viewed themselves positively as NYC teachers and that increases in positive self‐perceptions were paralleled by increases in affinity toward living in NYC and NYC schools. Those not inclined to NYC teaching (6/22) expressed increasingly negative views of themselves as NYC teachers, NYC life, and urban education generally. The research provides insights into what Noyce Scholar undergraduates in science education think about when considering a teaching career in urban school districts.     

Learning the Learning Cycle: The Differential Effect on Elementary Preservice Teachers

This study examined the difficulties and factors that led to understanding the learning cycle teaching strategy. Participants included 83 preservice elementary teachers (PTs) enrolled in multiple sections of a science methods course taught by the same professor, one of the authors of this study. Analysis revealed that there were four categories of PTs, ranging from Enthusiastic to Fearful students, distinguished by their science content background and attitudes to science. High achieving students, successful in science courses, felt confused by the learning cycle that was so different from their previous science learning experiences and formed mindsets against learning it. Average students who expressed disinterest or even fear of science embraced it as their first successful science learning experience. Multiple exposures to the learning cycle were necessary to overcome these mindsets. Most PTs in all categories increased in their understanding of the learning cycle and perceived it as an effective method for allowing students to construct their understanding of science.     

The Science Teaching Self‐Efficacy of Prospective Elementary Education Majors Enrolled in Introductory Geology Lab Sections

This study examined prospective elementary education majors' science teaching self‐efficacy while they were enrolled in an introductory geology lab course for elementary education majors. The Science Teaching Efficacy Belief Instrument Form B (STEBI‐B) was administered during the first and last lab class sessions. Additionally, students were asked an open‐ended question to describe their experience in the education majors' geology lab. The results of the STEBI‐B were analyzed using paired t‐tests to determine whether the students changed their personal science teaching efficacy (PSTE) and science teaching outcome expectancy (STOE). Results of this study indicate a significant increase in PSTE. No significant differences were found in STOE. This study suggests that science content courses designed for education majors may lead to a positive change in science teaching self‐efficacy and has implications for teacher educators in preparing science content courses for their teacher preparation program.     

Examination-Type Preferences of College Science Students and Their Faculty in Israel and USA: A Comparative Study

The science-examination preferences of college science students and their science faculty were surveyed, using the TOPE questionnaire at a teacher training and a community college in Israel and the U.S., respectively. The results obtained in the two countries were “intrally” and “interly” compared, in total and by gender, in terms of significant/no significant differences in the preferences made and the reasons provided by the students and faculty for their ranking. The findings suggest that: (a) college science students prefer mostly, the Israelis more so than the Americans, the nonconventional, written exams in which time is unlimited and any materials are allowed; (b) American college science students prefer the traditional class science examination (G) significantly more than their Israeli counterparts; (c) the preference of higher order cognitive skills (HOCS)-oriented exams (B. I and H) is significantly higher for female science students in Israel compared with no gender difference concerning the preferred examinations in the US, and rejection of oral examinations by all in both countries, significantly more by female students; and (d) there exists a significant gap between the preferred type of examinations of science students and their faculty in both countries. In view of the HOCS-orientation and the goal of conceptual understanding in current reforms of science education worldwide, the consonance between these curriculum objectives and examination practices is advocated. This, in turn, requires that provisions be made to lessen the gap between science teachers and their students' examination type preferences for better science learning to occur.     

Preparing Pre‐Service Teachers to Teach Mathematics in Inclusive Classrooms: A Three‐Year Case Study

Federal and state regulations mandating inclusion of students with disabilities in general education classes have made it essential to create pathways for pre‐service teachers to develop skills to teach content to diverse groups of students. The study uses a framework suggested by the relationship between teacher attitude and teacher behavior ( Fullan, 1982 ), teacher beliefs and practice, and self‐efficacy and behavioral change ( Bandura, 1977 ). The purpose of the study was to examine changes, if any, in three cohorts of general education teacher candidates' (n=13, n=8, n=5) attitudes toward teaching mathematics to students with disabilities after participating in focused instructional experiences which provided both information and vicarious positive teaching activities in special education. Data collected included pretest and posttest scores for each of the three cohorts and journal entries. Little or no change in attitude towards students with disabilities and mathematics, and efficacy to teach students with disabilities was observed for the year one and year two cohorts. In the third year the modules were combined with a structured field experience. The data collected from the third year cohort suggested a positive trend in attitude as measured by the survey data and field experience journal data. Future study with larger samples is needed.     

Improving Science Teaching for All Students

An inservice program designed to enhance the knowledge and skills of elementary school teachers with respect to science content, effective teaching strategies, and gender equity was implemented as a semester-long course. During the course, teachers explored new science content in chemistry and physics and then collaboratively developed lesson plans from it based on hands-on, discovery-centered learning, enmeshed in strategies that could maximize female student interest and participation in science. Teachers tried out their lessons between course sessions in their own classrooms and then collaboratively reflected on their progress and problems in subsequent sessions. Program results were positive for both teachers and students. Teachers reported significant increases in both their level of knowledge of and their confidence in teaching chemistry and physics concepts, as well as in their knowledge of strategies for addressing gender inequities. Project students' attitudes, particularly those of the girls, improved for some dimensions, remained stable for others, and declined for one; the girls also increased their level of active participation in science activities. Overall, the project seems to have had a positive impact on science teaching content and pedagogy, and on student (especially girls') interest and active participation in science.     

The Border Crossings of a Multicultural Science Education Enthusiast

Jill was a preservice science education student who wanted to make science more accessible to all students. This study is an examination of the “borders” she encountered as she completed her student teaching in a cultural setting that was different from her own. Her student teaching experience was documented through interviews, participant observations, field notes, lesson plans, and a journal. An inductive analysis of the documents and a context chart of the coded data revealed that Jill encountered the (a) cultural border of her students, (b) cultural border of science instruction, and (c) cultural border of the school. While some borders were crossed, others were not. This study suggests that during field experiences, preservice teachers may encounter multiple cultural borders, some consistent and some inconsistent with their instructional philosophy. As student teachers work with diverse populations, supervisors and cooperating teachers need to recognize the borders student teachers will encounter and encourage student teachers to examine their beliefs about practice as a means to acknowledge and understand the encountered borders.
