Novice teachers’ conceptions of fairness in inclusion classrooms

The issue of “fairness” troubles some general education teachers, who may be reluctant to teach students with disabilities. Journals written by 47 general education preservice and novice teachers were data sources for examining teachers’ concerns about fairness. Five areas of concern emerged: general responses, definitions of fairness, dealing with students, classroom applications (e.g., grading), and negative views. These themes are illustrated and discussed within the theoretical framework of principles of distribution of benefits. Suggestions are offered for helping teacher education students move toward acceptance of needs-based principles of fairness.     

Can LEDs help with art conservation? – Impact of different light spectra on paint pigment degradation

The impact of the spectral composition of light on the discoloration of paint pigments has been investigated for the case of lead chromate sulfate, an unstable yellow pigment used by Vincent van Gogh and other painters. With LEDification, museum lighting is moving from using halogen to LED lamps. LED light sources have a significantly different spectral composition than halogen lamps. To understand the impact of these differences on pigment stability, the wavelength dependence of pigment discoloration was determined. Contrary to the expectation that lower wavelength photons induce more damage than higher wavelength ones, UV (394?nm), blue, and cyan light all lead to similar levels of discoloration of a pigment for the same level of radiant power. By understanding this wavelength dependence, it becomes possible to create white light LED lamps with a spectral composition tuned to minimize the degradation effect. An existing LED solution with a modified emission indeed resulted in 30% less color change in the experiment than halogen. Furthermore, a method is proposed to optimize the LED spectra by tuning to the properties of each specific artifact. Simulations show that this can reduce the damage of the light source by 45% in specific cases.     

‘Doing research was inspiring’: building a research community with teachers

This paper reports on a mixed-methods study related to K–12 teachers’ understandings of what research is, and what enables or inhibits teacher use of research in the classroom towards informing their instructional practices. In a collaboration exemplifying school board and university partnerships, we examined the nature of associations between teachers and education research(ers). Our findings indicated that teachers felt both connected and disconnected to research practices in education. Participants suggested ways to establish and sustain better links and collaborations among the communities of teaching and research. This paper emphasizes the importance of universities, schools and teachers working together to conduct meaningful research and apply current knowledge in the field of education.     

Beyond strategies: teacher beliefs and writing instruction in two primary inclusion classrooms

Links between teachers' pedagogical beliefs and teaching practices were investigated with respect to process writing instruction. Participants included 5 teachers, 44 general education students, and 23 special education students in 2 elementary multi-age inclusion classrooms. Findings suggested that, although the teachers shared similar views on inclusion and were convinced of the uniqueness of their respective instructional approaches, they nuanced their writing instruction to conform to their implicit theories about teaching, learning, and disability. One set of teachers believed that the writing "breakdowns" of students with disabilities required a structural approach-sequenced, individualized, phonics-based instruction targeting individual performance levels. Another set of teachers advocated a relational approach, wherein students with disabilities are "protected" and "empowered" in learning communities characterized by shared activities, student choice, and interpersonal communication.     

Responding to Students’ Learning Preferences in Chemistry

This paper reports on a teacher’s and his students’ responsiveness to a new tetrahedral-oriented (Mahaffy in J Chem Educ 83(1):49–55, 2006) curriculum requiring more discursive classroom practices in the teaching of chemistry. In this instrumental case study, we identify the intentions of this learner-centered curriculum and a teacher’s development in response to this curriculum. We also explore the tensions this teacher experiences as students subsequently respond to his adjusted teaching. We use a Chemistry Teacher Inventory (Lewthwaite and Wiebe in Res Sci Educ 40(11):667-689, 2011; Lewthwaite and Wiebe in Can J Math Sci Technol Educ 12(1):36–61, 2012; Lewthwaite in Chem Educ Res Pract. doi:10.1039/C3RP00122A, 2014) to assist the teacher in monitoring how he teaches and how he would like to improve his teaching. We also use a student form of the instrument, the Chemistry Classroom Inventory and Classroom Observation Protocol (Lewthwaite and Wiebe 2011) to verify the teacher’s teaching and perception of student preferences for his teaching especially in terms of the discursive processes the curriculum encourages. By so doing, the teacher is able to use both sets of data as a foundation for critical reflection and work towards resolution of the incongruence in data arising from students’ preferred learning orientations and his teaching aspirations. Implications of this study in regards to the authority of students’ voice in triggering teachers’ pedagogical change and the adjustments in ‘teachering’ and ‘studenting’ required by such curricula are considered.     

Books and Websites,E-Journals or Print: If the Source Fits,Use It

Despite the ever-growing range of media types, formats, and information-access options, students are often instructed to only use specific sources in their research. They are sometimes even given strict guidelines, prescribing how many of each they need to, or may, cite. It is important not to lead students to believe there is a formula for the ideal works cited for all research topics. In contrast, students should learn to think critically about the content and appropriateness of each potential source rather than choosing it only because it is a book, a journal article, a Website, etc. This article argues that requiring students to use, or not use, a source based solely on its format or media type encourages students to choose sources for wrong reasons, pushing critical thinking and source-content evaluation to the periphery of their research processes.     

Understanding Scale: Powers of Ten

The classic film “Powers of Ten” is often employed to catalyze the building of more accurate conceptions of scale, yet its effectiveness is largely unknown. This study examines the impact of the film on students’ concepts of size and scale. Twenty-two middle school students and six science teachers participated. Students completed pre- and post-intervention interviews and a Scale Card Sorting (SCS) task; all students observed the film “Powers of Ten.” Experienced teachers’ views on the efficacy of the film were assessed through a short written survey. Results showed that viewing the film had a positive influence on students’ understandings of powers of ten and scale. Students reported that they had more difficulty with sizes outside of the human scale and found small scales more difficult to conceptualize than large scales. Students’ concepts of relative size as well as their ability to accurately match metric sizes in scientific notation to metric scale increased from pre- to post-viewing of the film. Experienced teachers reported that the film was a highly effective tool. Teachers reported that the design of the film that allowed students to move slowly from the human scale to the large and small scales and then quickly back again was effective in laying the foundation for understanding the different scales.
