Carbonel, Cyril; Grasset, Sébastien; Maysonnave, Jean – Physics Teacher, 2018
In astronomy, methods such as direct imaging or interferometry-based techniques (Michelson stellar interferometry for example) are used for observations. A particular advantage of interferometry is that it permits greater spatial resolution compared to direct imaging with a single telescope, which is limited by diffraction owing to the aperture of…

Sangangula, Londaka Amasio – Online Submission, 2016
The purpose of this study was to provide views of teachers and pupils on large class size and its effects on teaching and English learning, at "Instituto Médio Politécnico do Namibe", and by showing that the large class scenario at IMP-Namibe may be attributed to various factors of which the most pertinent is the imbalance between the…

Bermingham, Aaron – Geographical Education, 2016
This study analysed the extent to which student-led inquiry is supported by fieldwork booklet design. Roberts' (2003) framework for learning through inquiry was used as lens for analysing the presence of student-led inquiry in the design of nine fieldwork booklets. Observations of teaching practice from two fieldwork activities were also analysed…

Turrin, Margie – Science Teacher, 2015
Data and data analysis are central to science and the complex world in which people live. Students need to practice working with data--addressed in the "Next Generation Science Standards" (NGSS Lead States 2013)--starting with small, self-collected data sets and moving on to larger, remotely collected data assemblages. Small data sets…

Hanson, Eric; Burakowski, Elizabeth – Science Teacher, 2015
For much of the northern United States, the months surrounding the winter solstice are a time of increased darkness, low temperatures, and frozen landscapes. Each year, the ubiquitous white ice crystals that blanket regions of the north go uninvestigated. Instead of hunkering down indoors with their classes, however, teachers can take advantage of…

Wagler, Amy; Wagler, Ron – Science Teacher, 2014
Every high school graduate should be able to use data analysis and statistical reasoning to draw conclusions about the world. Two core statistical concepts for students to understand are the role of variability in measures and evaluating the effect of a variable. In the activity presented in this article, students investigate a scientific question…

Dewhurst, Marit – Harvard Education Press, 2014
In this lively and groundbreaking book, arts educator Marit Dewhurst examines why art is an effective way to engage students in thinking about the role they might play in addressing social injustice. Based on interviews and observations of sixteen high schoolers participating in an activist arts class at a New York City museum, Dewhurst identifies…

Ortega, Irasema; Luft, Julie A.; Wong, Sissy S. – School Science and Mathematics, 2013
Early career science teachers are often assigned to classrooms with high numbers of English language learners (ELLs). For the underprepared early career science teacher, these circumstances are challenging. This study examines the changes in beliefs and practices of an early career science teacher who taught high numbers of ELLs in an urban…

Iowa Department of Education, 2012
Case studies of Authentic Intellectual Work (AIW) in the Iowa project included four high schools that have been practicing this professional development model for the last five years. The schools, AHST Secondary School, Cedar Falls High School, Spencer High and Middle Schools and Valley High School were visited in April, 2011. The visits included…

Francisco, John M.; Maher, Carolyn A. – Journal of Mathematics Teacher Education, 2011
There is a documented need for more opportunities for teachers to learn about students' mathematical reasoning. This article reports on the experiences of a group of elementary and middle school mathematics teachers who participated as interns in an after-school, classroom-based research project on the development of mathematical ideas involving…

Poli, Maria-Serena; Capodivacca, Marco – Science Teacher, 2011
Continental margins are an important part of the ocean floor. They separate the land above sea level from the deep ocean basins below and occupy about 11% of Earth's surface. They are also economically important, as they harbor both mineral resources and some of the most valuable fisheries in the world. In this article students investigate North…

Guglielmino, M.; Gratton, L. M.; Oss, S. – Physics Education, 2010
We propose a simple, direct estimate of the Sun's diameter based on penumbra observation and measurement in a two-level approach, the first for middle-school pupils and making use of simple geometrical arguments, the second more appropriate to high-school students and based on a slightly more sophisticated approach. (Contains 5 figures.)

Demir, Abdulkadir; Abell, Sandra K. – Journal of Research in Science Teaching, 2010
The purpose of this phenomenographic study was to: (a) gain an understanding of the meaning of inquiry held by beginning science teachers and their instructors in an Alternative Teacher Certification Program (ATCP); and (b) compare science teachers' views of inquiry with what they learned in their ATCP. Participants were four beginning science…

Brilhart, Dan – Journal of Ethnographic & Qualitative Research, 2010
This postmodern ethnographic study of teacher conceptualization of teaching expanded the findings of other research regarding the disconnect between teacher preparation programs and classroom teaching by exploring how personal and professional knowledge and identities are synthesized for 10 in-service teachers. Teachers in the study filtered…
