The Impact of an Engineering Design Curriculum on Science Reasoning in an Urban Setting 总被引:2,自引:2,他引:0
Eli M. Silk Christian D. Schunn Mari Strand Cary 《Journal of Science Education and Technology》2009,18(3):209-223
This study examines the use of engineering design to facilitate science reasoning in high-needs, urban classrooms. The Design
for Science unit utilizes scaffolds consistent with reform science instruction to assist students in constructing a design
solution to satisfy a need from their everyday lives. This provides a meaningful context in which students could reason scientifically.
Eighth grade students from two urban schools participated in the unit. Both schools contained large percentages of racial/ethnic
minority and economically disadvantaged students. Students demonstrated statistically significant improvement on a paper-and-pencil,
multiple-choice pre and post assessment. The results compare favorably with both a high-quality inquiry science unit and a
traditional textbook curriculum. Implications for the use of design-based curricula as a viable alternative for teaching science
reasoning in high-needs, urban settings are discussed.

Lifelong science literacy begins with attitudes and interests established early in childhood. The use of trade books (i.e.,
a literary work intended for sale to the general public) in North American school classrooms to support the development of
science literacy invites an examination of the quality of science content disseminated to students. A total of 116 trade books
were examined to: (a) determine the degree to which science trade books complement expected science knowledge outcomes outlined
in school curricula, and (b) compare trade book content to the goals of scientific literacy. Analysis across four science
topics, Dinosaurs, Space, Inheritance, and Growth and Life Properties, revealed that this body of children’s literature is
inconsistent in its coverage of curricular goals and elements of scientific literacy. Because trade books represent children’s
first exposure to science, these shortcomings should be addressed if these books are to be maximally effective in promoting
science literacy. Implications for using trade books in the classroom are discussed.

More than a conversation: using cogenerative dialogues in the professional development of high school chemistry teachers 总被引:1,自引:0,他引:1
Sonya N. Martin Kathryn Scantlebury 《Educational Assessment, Evaluation and Accountability》2009,21(2):119-136
This paper focuses on content-based and pedagogical instructors’ use of cogenerative dialogues to improve instructional practice
and to evaluate program effectiveness in a professional development program for high school chemistry teachers. We share our
research findings from using cogenerative dialogues as an evaluative tool for general assessment of various program-related
issues. We discuss how engaging students in cogenerative dialogues improved teaching and learning in chemistry and chemistry
education courses. This research provides insights and direction for improving content-based professional development programs
for science teachers and the learning experiences of high school science students. Cogenerative dialogue has the potential
to expand evaluation methodologies that will position participants more centrally in not only the collection of data, but
also the analysis of these data to catalyze transformative practices in educational programs.

In his December editorial on Michael Reiss, Kenneth Tobin (Cult Stud Sci Educ 3:793–798, 2008), raises some very important questions for science and science teachers regarding science education and the teaching of creationism
in the classroom. I agree with him that students’ creationist ideologies should be treated not as misconceptions but as worldviews.
Because of creationism’s peculiarly strong political links though, I argue that such discussion must address three critical
and interconnected issues, including the uncertain state of teaching evolution in public schools nationally, the political
convergence of the creationist political beliefs with bigoted worldviews, and creationism’s inherent contrariness to science
and human progress. I suggest that we as science educators therefore not consider all sides to be equally right and to instead
take side against the politics of creationism. I also argue that we need much more serious discussion on how to better teach
science to students who hold creationist worldviews, and that science educators such as Reiss need to be part of that.

Science educators have yet to identify ways to enable inner city African American high school students to experience success
in science. In this paper, we argue that understanding the ways in which cultural practices from fields outside of school
mediate what happens inside classrooms and contribute to the learning of students is crucial to addressing current disparities
in science performance. Specifically, we explore the significance of movement expressiveness dispositions to the lives and
the learning of economically disadvantaged African American youth. These particular dispositions have been repeatedly observed
in our research, and they can be important resources for the creation of individual emotional energy, collective solidarity,
and heightened engagement in learning activities since they provide resources for the (re)shaping of identity. Thus movement
expressiveness dispositions hold potential for transforming the teaching and learning of these students.

Dr. Sreyashi Jhumki Basu was a scholar committed to equity and social justice in science education who passed away in December
2008. In this essay, I describe Jhumki’s research and the call to action her life’s work has laid out for the science education
community. In particular, I draw attention to the role of critical science agency in learning and the democratic science pedagogy
model that Jhumki developed to support students in crafting such agency.

A lack of congruency between the teaching and learning of science and the student’s personal worlds has long been recognised
by the international science education community as an issue deserving space in the research agenda. The purpose of this study
was to explore the diversity of student reactions when subcultures such as family, community peers, and personal worldviews
are considered along side the subculture of school science. Two-hundred and fifty students from urban and provincial schools
in the northeastern region of Colombia (South America) participated. From this group, 18 students were interviewed. It was
observed that students adopt a compartmentalisation of knowledge that is evident as both an avoiding strategy in the classroom
and as a mechanism to differentiate between the natural world of their everyday situations and the one portrayed by a Westernised
science instruction in the classroom. The findings reflect how multiple worldviews correlate with student frameworks as implanted
by school science.

Since many teachers and students recognize other kinds of knowledge (faith) based on other ways of knowing, consideration
of these realities is appropriate for the science education community. Understanding the multitude of ways that clergy view
relationships between science and faith (i.e. alternative ways of knowing) would assist in understanding various ways that
people address complex issues arising from ideas about science and faith. We administered a questionnaire composed of multiple-choice
and short answer items to 63 United Methodist ministers. Findings included (1) that formal, organized faith contexts (e.g.
church services) serve as informal science education opportunities, (2) participants demonstrated considerable diversity regarding
the types of relationships developed between science and faith, and (3) participants recognized a need exists for better understandings
of science and its relationship to faith for them, their colleagues, and their congregations.

Fostering High School Students’ Conceptual Understandings About Seasons: The Design of a Technology-enhanced Learning Environment 总被引:1,自引:0,他引:1
The purpose of this study is to understand in what ways a technology-enhanced learning (TEL) environment supports learning
about the causes of the seasons. The environment was designed to engage students in five cognitive phases: Contextualisation,
Sense making, Exploration, Modeling, and Application. Seventy-five high school students participated in this study and multiple
sources of data were collected to investigate students’ conceptual understandings and the interactions between the design
of the environment and students’ alternative conceptions. The findings show that the number of alternative conceptions held
by students were reduced except for the incorrect concepts of “the length of sunshine” and “the distance between the sun and
the earth.” The percentage of partial explanations held by students was also reduced from 60.5 to 55.3% and the percentage
of students holding complete scientific explanations after using Lesson Seasons rose from 2.6 to 15.8%. While some students
succeeded in modeling their science concepts closely to the expert’s concepts, some failed to do so after the invention. The
unsuccessful students could not remediate their alternative conceptions without explicit guidance and scaffolding. Future
research can then be focused on understanding how to provide proper scaffoldings for removing some alternative concepts which
are highly resistant to change.

This survey study explored high school science teachers’ challenges and needs specific to their growing English language learning
(ELL) student population. Thirty-three science teachers from 6 English as a Second language (ESL)-center high schools in central
Virginia participated in the survey. Issues surveyed were (a) strategies used by science teachers to accommodate ELL students’
special needs, (b) challenges they experienced, and (c) support and training necessary for effective ELL instruction. Results
suggest that language barriers as well as ELL students’ lack of science foundational knowledge challenged teachers most. Teachers
perceived that appropriate instructional materials and pedagogical training was most needed. The findings have implications
for science teacher preservice and inservice education in regard to working with language minority students.

This study describes how teachers use their personal knowledge of a school district and their students to cope with teaching
under stressful situations associated with economic, social, and institutional factors. The 3 teachers dealt with these issues
in unique ways, focusing on helping students to overcome negative perceptions, value the importance of an education, and build
strong relationships. A model of multicultural science professional development is proposed that complements the strengths
that these teachers have. A task for science educators working with teachers and administration in schools and districts that
are “critically low performing” is to support everyone in implementing pedagogical methods aimed at empowerment, social justice,
and high achievement for all students.

The article explores the role of immigrant parents in middle school science as both teachers and learners as part of an urban
middle school curriculum, the Linking in Food and the Environment (LiFE) program. The curriculum engaged parents as partners
with science teachers to teach science through food. Over a 2-year period, parents attended a series of bilingual workshops,
collaborated with classroom teachers, managed activities, guided student inquiry, and assisted in classroom management. The
following study analyzes the role of culture, language, and identity as four mothers navigated their position as ‘insiders’
in a science classroom.

Indigenous knowledge and science revisited 总被引:3,自引:3,他引:0
This article provides a guided tour through three diverse cultural ways of understanding nature: an Indigenous way (with a
focus on Indigenous nations in North America), a neo-indigenous way (a concept proposed to recognize many Asian nations’ unique
ways of knowing nature; in this case, Japan), and a Euro-American scientific way. An exploration of these three ways of knowing
unfolds in a developmental way such that some key terms change to become more authentic terms that better represent each culture’s
collective, yet heterogeneous, worldview, metaphysics, epistemology, and values. For example, the three ways of understanding
nature are eventually described as Indigenous ways of living in nature, a Japanese way of knowing seigyo-shizen, and Eurocentric
sciences (plural). Characteristics of a postcolonial or anti-hegemonic discourse are suggested for science education, but
some inherent difficulties with this discourse are also noted.

In this response to commentaries by Ali Sammel, Jhumki Basu and Alberto Rodriguez, I present my perspective on three important
issues raised by the commentators. These issues relate to the role of a researcher in her field settings and society, the
critique of science and science education as oppressive dominant discourses, and co-opting participants as researchers. I
argue that researchers should work actively for progressive change in discursive fields such as educational research, in which
they are firmly embedded rather than playing an interventionist role in field settings where their discursive positionality
maybe temporary and not that rooted. Regarding the critique of science and science education, my response favors a perspective
wherein an understanding of the marginalization and oppression of non-western communities caused by western science and science
education is counterbalanced by an appreciation of the ways in which marginalized communities can use science and science
education for affecting progressive change. Lastly, I recognize the value of co-opting participants in writing and communication
of research.

This article focuses upon programs for undergraduate women in science and engineering, which are a strategic research site
in the study of gender, science, and higher education. The design involves both quantitative and qualitative approaches, linking
theory, method, questions, and analyses in ways not undertaken previously. Using a comprehensive, quantitative, cross-institutional,
and longitudinal method, two extreme groups of programs are distinguished: those associated with the “most successful” and
“least successful” outcomes in undergraduate degrees awarded to women in science and engineering. Qualitative analyses of
interview data with key players in the programs in these two groups point to ways in which definitions of issues, problems,
and solutions diverge (as well as converge), and thus to conceptual underpinnings that have important real-life consequences
in these organizational settings of higher education. The programs that regard issues, problems, and solutions of women in
science and engineering as rooted in “institutional/structural-centered,” as opposed to “individual/student-centered,” perspectives
are associated with the most positive outcomes in undergraduate degrees awarded to women in science and engineering.

Our 5-year professional development intervention is designed to promote elementary teachers’ knowledge, beliefs, and practices
in teaching science, along with English language and mathematics for English Language Learning (ELL) students in urban schools.
In this study, we used an end-of-year questionnaire as a primary data source to seek teachers’ perspectives on our intervention
during the first year of implementation. Teachers believed that the intervention, including curriculum materials and teacher
workshops, effectively promoted students’ science learning, along with English language development and mathematics learning.
Teachers highlighted strengths and areas needing improvement in the intervention. Teachers’ perspectives have been incorporated
into our on-going intervention efforts and offer insights into features of effective professional development initiatives
in improving science achievement for all students.

Developing Science Pedagogical Content Knowledge Through Mentoring Elementary Teachers 总被引:1,自引:0,他引:1
Ken Appleton 《Journal of Science Teacher Education》2008,19(6):523-545
Elementary teachers are typically hesitant to teach science. While a limited knowledge of science content is a reason for
this, limited science pedagogical content knowledge (PCK) has emerged as another reason in recent research. This study constitutes
two case studies of a professional development program for elementary teachers involving mentoring by a university professor.
The mentor took the role of a critical friend in joint planning and teaching of science. The study examines the nature of
the mentoring relationship and reports the type of teacher learning that occurred, with a particular focus on the teachers’
development of science PCK.
