Student Visual Communication of Evolution

Despite growing recognition of the importance of visual representations to science education, previous research has given attention mostly to verbal modalities of evolution instruction. Visual aspects of classroom learning of evolution are yet to be systematically examined by science educators. The present study attends to this issue by exploring the types of evolutionary imagery deployed by secondary students. Our visual design analysis revealed that students resorted to two larger categories of images when visually communicating evolution: spatial metaphors (images that provided a spatio-temporal account of human evolution as a metaphorical “walk” across time and space) and symbolic representations (“icons of evolution” such as personal portraits of Charles Darwin that simply evoked evolutionary theory rather than metaphorically conveying its conceptual contents). It is argued that students need opportunities to collaboratively critique evolutionary imagery and to extend their visual perception of evolution beyond dominant images.     

Teacher agency in the performance of inquiry-oriented science curriculum reform

In this commentary, I consider several theoretical and analytical aspects of Tang Wee Teo and Margery Osborne??s case study. I begin by identifying structuralist and cultural themes in Tang Wee and Margery??s theoretical model of human activity. Next, I offer an alternative interpretation for Tang Wee and Margery??s reported findings in terms of the notion of multiple teacher agencies. After that, I discuss the dramaturgical or theatrical nature of the symbolic interactionist model used by Tang Wee and Margery, focusing specifically on the issues of teacher role-taking and curriculum authorship. The paper then ends with a discussion about the significance of Tang Wee and Margery??s study wherein I emphasize the need for science education researchers to give more careful consideration to teacher agency and the analytical value of theatrical metaphors from the field of social dramatism.

The effect of orthographic depth on letter string processing: the case of visual attention span and rapid automatized naming

The present study investigated whether orthographic depth can increase the bias towards multi-letter processing in two reading-related skills: visual attention span (VAS) and rapid automatized naming (RAN). VAS (i.e., the number of visual elements that can be processed at once in a multi-element array) was tested with a visual 1-back task and RAN was measured in a serial letter naming task that introduced a novel manipulation (some letter sequences formed frequent words). Spanish-Basque and French-Basque bilingual children were tested at early (30 children in 1st and 2nd grade), and more advanced (24 children in 3rd, 4th and 5th grade) stages of reading acquisition to investigate whether they would be differently biased towards multi-letter processing due to reading in two shallow (Spanish, Basque), or a deep and a shallow (French, Basque) orthography. The French-Basque bilinguals, who read in a deep orthography, were expected to rely on larger orthographic units in reading and thus to be more biased towards multi-letter processing in both tasks. This was expected to be reflected by: (a) a uniform distribution of attention across letter strings in the VAS task, and (b) a greater interference of the embedded words on letter-by-letter naming in RAN, leading to longer naming times. The expected group differences were observed in the more advanced readers, with French-Basque bilinguals showing a wider distribution of VAS across letter strings and longer naming times in RAN.     

ICT in Portuguese reference schools for the education of blind and partially sighted students

Technology has become an essential component in our society and considering its impact in the educational system, Information and Communication Technologies (ICT) cannot be dissociated from the educational process and, in particular, from pedagogical practices adopted for students who are blind or partially sighted. This study focuses on Portuguese reference schools for the education of blind and partially sighted students, regulated by the Decree-Law No. 3/2008, in which are concentrated the human and material resources that can offer an educational response with quality for these students with special education needs. The study intends to analyse the perceptions of the teachers, who teach visually impaired students in middle school and secondary school education in these reference schools, of their knowledge, teaching and training in the area of ICT, as well as of the real ICT integration in the teaching and learning of these students. A survey, which has been applied to these teachers in the 2012/13 school year, was adopted as a method of data collection. The results reveal a sample confident in their technological capabilities, however with little resourcefulness in some tools and software specific to the area of visual impairment and a very significant number of teachers ignoring many of these. The implementation of ICT with students who have visual disabilities is lower compared with the sighted students. The lack of specific training is considered to be the main obstacle for teachers, with regard to the real integration of ICT in the teaching and learning of these students.     

Psychometry of the Teacher's Sense of Efficacy Scale in Spanish Teachers' Education

Our objective was to test the factorial validity of the different versions (TSES-24, TSES-12, and TSES-11) of the Teacher's Sense of Efficacy Scale in Spanish preservice teachers'. The participants were 358 preservice teachers. The confirmatory factor analysis showed inadequate fit indexes for both TSES-24 and TSES-12 but adequate fit indexes for TSES-11, which was invariant across gender. The reliability analysis showed appropriate values. The global factor for teachers' sense of efficacy and the three factors that constitute it positively predicted intrinsic motivation and life satisfaction. The global factor for sense of efficacy and the classroom management and student engagement factor negatively predicted amotivation. The results support the use of the TSES-11 three-factor model, rather than TSES-24 or TSES-12, for Spanish preservice teachers.
