Empowering Families in Hands‐on Science Programs

Parental involvement in schools has been documented as a positive influence on children's achievement, attendance, attitudes, behavior, and graduation rate, regardless of cultural background, ethnicity, and socioeconomic status ( National Parents and Teachers Association, 1998 ). Unfortunately, it has been difficult in today's world of working parents to get them actively involved in science, mathematics, and technology programs and to maintain this involvement in upper‐elementary and secondary schools. This study reports on the Science: Parents, Activities, and Literature project's attempt to get parents productively involved in their children's hands‐on science program. The results illustrate that (a) parents will become involved and they find their involvement a positive experience, (b) teachers appreciate parents' contributions as an instructional resource, and (c) students perceive the increased parental involvement positively.     

The Indiana Science Initiative: Lessons from a Classroom Observation Study

The Indiana Science Initiative (ISI) is a systemic effort to reform K–8 science education. The program provides teachers with professional development, reform‐oriented science modules, and materials support. To examine the impact of the initiative's professional development, a participant observation study was conducted in the program's pilot year. Five teachers in grades 3–6 were observed and interviewed as they implemented the ISI‐provided modules. Analysis of the observation data revealed that the teachers incorporated each of the features of inquiry science instruction. However, they did not consistently teach in a way that was aligned with the intent of the ISI. Examination of interview data provided insight into influences on teachers' use of inquiry with the ISI‐provided modules. These data revealed that teachers were aware of the intent of the ISI and attempted to align their instruction. However, teachers were influenced by their perceptions of students' behavior and abilities as well as timing and the appropriate level of teacher control needed to facilitate science instruction. The research suggests that professional development activities should prepare teachers to help learners evaluate explanations against alternatives, connect explanations to scientific knowledge, and provide strategies to address teachers' perceptions of students, timing, and teacher control.     

Family Mathematics Nights: An Opportunity to Improve Preservice Teachers' Understanding of Parents' Roles and Expectations

Providing preservice teachers with opportunities to engage with parents and begin to see them as collaborators in their children's education is a persistent challenge in mathematics methods courses and teacher preparation programs more broadly. We describe the use of family mathematics nights as a model for engaging parents and preservice teachers. These events helped preservice teachers feel more comfortable in working with parents, while also giving them a friendly space for learning more about parents, the ways they work with their children, and activities they do with their children. Incorporating surveys about parents' needs and suggestions for preservice teachers allowed us to use the results as a catalyst for fostering discussions around parent engagement later in the methods course.     

Examining the Conceptual Organization of Students in an Integrated Algebra and Physical Science Class

The cross-disciplinary context of density and slope was used to compare the conceptual organization of students in an integrated algebra and physical science class (SAM9) with that of students in a discipline-specific physical science class (PSO). Analyses of students' concept maps indicated that the SAM9 students used a greater number of procedural linkages to connect mathematics and science concepts on the SAM9 students' maps than did the PSO students. The maps produced by SAM9 students also tended to show a more compartmentalized approach to thinking about the content of the two disciplines, a finding contrary to the researcher's original assertion. Traditional teaching territories and conceptual complexity were examined as possible explanations for the discrepancy between the predicted and actual outcomes.     

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.     

Gender Differences in Attitudes toward Environmental Science

This study examined the role of gender in the areas of environmental education that included environmental knowledge, attitudes, behaviors, and comfort levels in the outdoors. The current study was part of a larger study designed to explore the effects of a treatment that consisted of 14 weeks of outdoor lessons conducted in the schoolyard as compared with a control group of students who had 14 weeks of traditional classroom environmental education lessons. This follow‐up study focused on gender and its effect on each of the areas studied. Researchers found significance in boys' and girls' attitudes toward the environment. Quantitative and qualitative data were used to offer an in‐depth view of students' environmental attitudes. The results from this study can have implications for science educators in an effort to capitalize on boys' and girls' interests in science to help them learn about environmental issues and to recruit both boys and girls into science careers.     

Student Perceptions of a Summer Ventures in Science and Mathematics Camp Experience

“As the world becomes increasingly technological, the value of (the ideas and skills of its population) will be determined in no small measure by the effectiveness of science, technology, engineering, and mathematics (STEM) education in the United States” and “STEM education will determine whether the United States will remain a leader among nations and whether we will be able to solve immense challenges in such areas as energy, health, environmental protection, and national security” (President's Council of Advisors on Science and Technology, 2010, p. vii). Research on the effectiveness of STEM‐focused school and other learning experiences (e.g., short‐term camps) on student attitudes and performance outcomes is sparse. In this study, we documented the influence of an intensive STEM summer program on high school students’ attitudes toward STEM concepts and interests in STEM careers. Attending the summer program was associated with gains on students’ attitudes toward some aspects of STEM as well as specific career interests. Notably, students reported statistically significant views of important aspects of STEM and their attitudes toward science and mathematics were more positive than their attitudes about engineering and technology.     

What Factors Affect Attitudes Toward Women in Science Held by High School Biology Students?

To achieve the goal of science for all Americans, students of both genders must believe that careers in science are equally appropriate for women. Yet male and female students in high school science classes do not have the same views of women in science. This study investigated the influence of 17 factors on high school students' attitudes toward women in science. Data were collected from 844 students enrolled in biology classes in an urban school district in Georgia. Multiple regression determined that the 17 factors significantly influence students' attitudes toward women in science, accounting for 28% of common variance. The four most significant factors - student gender, science ability, level of education the student plans to complete, and career interest-accounted for 24.6% of total variance. Female students who have high science ability, plan to complete high levels of education, and who have career interests in science showed more favorable attitudes toward women in science. Males with low science ability, low levels of education they plan to complete, and no interest in science as a career had the least favorable attitudes toward women in science. Male students with less positive attitudes toward science careers for women need to be included in programs aimed at encouraging all students to consider science careers.     

Putting People Back Into Science: Using Historical Vignettes

Current science education research reports that students do not embrace an understanding of the nature of science. Furthermore, few curriculum materials emphasize the nature of science. This paper suggests an effective technique for including the nature of science in existing courses. Using Wandersee's story form model, historical vignettes describe brief episodes from the lives of scientists. They are designed to take only about ten minutes of class time, provide content information, and promote examination of the nature of the scientific enterprise by generating discussion. They help students connect the present and past, show the evolution of the ideas they are learning, and make the information more interesting.     

Just Like All the Other Humans? Analyzing Images of Scientists in Children's Trade Books

Despite the efforts of researchers and national science organizations to recruit more women and minorities into the science and engineering workforce, these fields are still largely dominated by White males. Research suggests that children's mental prototypes of the scientist include a variety of negative and stereotypical features that may contribute to decisions not to pursue a career in science among underrepresented groups. This study examines 1,656 images of scientists in children's nonfiction trade books, which are often used in classrooms and are many children's first introduction to science, to determine the extent to which these depictions perpetuate the stereotypical standard image of the scientist. Results indicate that while many elements of the stereotypical scientist image are not prevalent in these titles, gender and race are causes for concern.     

Assessing Preservice Teachers' Beliefs about the Teaching and Learning of Mathematics and Science

With increased study of teachers' beliefs about science and mathematics teaching in recent years, there is a need for instruments that assess beliefs in both content areas. Moreover, early field experiences in schools and professional development efforts may influence the beliefs that preservice and in‐service teachers develop, and instruments for this purpose are limited. This article describes the development and validation of the Confidence, Commitment, Collaboration, and Student thinking in Mathematics and Science (CCCSMS) beliefs scales, a set of 10 six‐item scales. Collectively, these scales measure teachers' self‐confidence in doing and teaching science and mathematics, confidence in understanding children's thinking and building models of that thinking, commitment to teaching science and mathematics from a standards‐based perspective, and commitment to collaborating with peers. The scales represent an efficient and effective way of assessing beliefs of large groups. Although this article focuses predominantly on development of the scales, results from initial use indicate that there are positive correlations between beliefs related to mathematics and beliefs related to science, but the correlations are low enough to show that many teachers think differently about the two subjects.     

Predictors of Science Fair Participation Using the Theory of Planned Behavior

The purpose of this study was to use The Theory of Planned Behavior (TPB) to examine factors that predict junior high and secondary students' attitude toward participating in a district science fair competition (attitude toward behavior), beliefs about who would approve or disapprove of participation in a science fair (subjective norm), and perceptions of control about participating in the science fair (perceived behavioral control). Factors used to predict these included gender, type of school (public or private), grade level, GPA, participation in a gifted class, participation in a research course, requirement to complete a science fair project, and level of anxiety about completing a science fair project. Three hundred three participants completed a standard TPB questionnaire and the State-Trait Anxiety Indicator. Multiple regression models revealed that subjective norm and participation in a gifted class were predictors of attitude toward the behavior. Attitude toward the behavior, the science fair project counting toward a grade in science class, the parent's level of education, and the science fair entry being required predicted subjective norm. A discriminant function analysis found that type of school (public or private), parents' level of education, participation in a research program at school, grade level, and trait anxiety were the strongest predictors of perceived behavioral control. It was concluded that science fair entry appears to be involuntary, in conflict with NSTA's Position Statement on Science Fairs. Typically junior high students (whose parents have a higher level of education) attending private schools are required to enter science fairs, and the entry counts toward a grade in science class.     

Re‐creating a Recipe for Science Instructional Programs: Adding Learning Progressions,Scaffolding, and a Dash of Reading Variety

The purpose of this article is to focus on the development and refinement of a science instructional design program arguing for the feasibility and usability of integrated reading and science instruction as implemented in third‐ and fourth‐grade science classrooms to meet the learning needs of diverse learners. These instructional components are easily inserted into existing programs that build students' science background knowledge and abilities to apply learning through scaffolded activities focused on (1) providing structured opportunities for students to engage in hands‐on activities; (2) increasing vocabulary knowledge and understanding of concept‐laden terms, and (3) reading paired narrative and informational science texts. Extensive research shows that as students transition from third to fourth grade and beyond, they are often challenged in science by new vocabulary coupled with new concepts. Active ingredients of our reconceptualized science instructional design program are narrative informational texts, hands‐on science activities, and science textbook(s).     

Children's Ideas About Weather: A Review of the Literature

It is generally accepted that children have their own understanding of how the world works prior to receiving formal science instruction. A great deal of research has been done to determine students' misconceptions related to the physical sciences; less has been done to understand children's ideas in the Earth sciences. This paper reports a synthesis of the existing research about children's misconceptions relating to weather, climate and the atmosphere. The scientifically accepted interpretations are presented in tandem with the children's naïve ideas. When possible, a source of the misconception is also presented. In many cases, students' misconceptions are not addressed in the curriculum, allowing them to exist unchallenged.     

Teaching children to add and subtract

At a 1980 conference, leading mathematics educators synthesized previous knowledge on children's early understanding of addition and subtraction and proposed central parameters for future research in these areas form a cognitive science perspective. We have, since 1980, increased our knowledge about how children learn to add and subtract, but we need to know more about the best ways for teachers to guide children as they construct knowledge of addition and subtraction.In this article, we review several studies that focus on an enhanced role for teachers in enabling children to learn addition and subtraction. These studies describe efforts that have been made to teach children to use diagrams and mediational representations, number sentences, or algorithms and procedures. The studies report improvement in children's problem-solving performance, but the impact of the efforts described on children's conceptual understanding is less clear. Thus, we analyze this research, pose questions on the relationship of instruction to children's knowledge construction, and propose a research agenda that we believe will enable us to understand how teaching can best help children learn to add and subtract.     

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.     

Promoting Equitable Biology Lab Instruction by Engaging All Students in a Broad Range of Science Practices: An Exploratory Study

This study examines what students enrolled in the honors and general sections of a high school biology course offered at the same school learn when they have an opportunity to participate in a broad or narrow range of science practices during their laboratory experiences. The results of our analysis suggest that the students enrolled in the general sections of the course made similar or larger gains than the students enrolled in the honors section of the course in their abilities to plan and carry out an investigation, argue from evidence, and write a science‐specific persuasive essay when these students had an opportunity to participate in a broad range of science practices. These findings suggest that laboratory experiences that give students an opportunity to participate in a broad range of science practices, although considered challenging by many teachers, have the potential to help all students become more proficient in science. The article concludes with a discussion of the implications of this study for classroom instruction and educational policy.     

Student's Attitudes Toward School and Classroom Science: Are They Independent Phenomena?

The purpose of this study was to examine 5th, 7th, and 10th graders' attitudes toward school and classroom science by means of questionnaires. In particular, the study hoped to determine (a) what students' attitudes are, (b) whether a relationship exists between these school and classroom science attitudes, and (c) what relationships grade level, gender, ethnicity, school/community type, expected GPA and science grade, and personally satisfying GPA and science grade have with students' attitudes toward school and classroom science. The results indicated that, although a statistically significant relationship did exist between students' attitudes toward school and toward classroom science, the relationship had no practical meaning. Females were slightly more positive about school than males. No gender differences were found with respect to classroom attitudes. Fifth graders held significantly more positive attitudes toward science than upper-grade students. None of the other variables was found to have any practical relationship to either of the attitudes.     

Metaphors Reveal Preservice Elementary Teachers' Views of Mathematics and Science Teaching

Typically, experiences shape one's attitudes toward the “thing” that is being experienced, whether it is a person, pet, movie, etc. Classroom experiences also shape one's attitudes toward a subject, teacher, learning, and so forth. Studies have shown that attitudes become more negative as students move from elementary to secondary schools. Elementary preservice teachers have had many classroom experiences by the time they reach their methods courses. These varied experiences have shaped their attitudes about the learning and teaching of mathematics and science.
