Truth is in the eye of the beholder: Perception of the Müller-Lyer illusion in dogs

Visual illusions are objects that are made up of elements that are arranged in such a way as to result in erroneous perception of the objects’ physical properties. Visual illusions are used to study visual perception in humans and nonhuman animals, since they provide insight into the psychological and cognitive processes underlying the perceptual system. In a set of three experiments, we examined whether dogs were able to learn a relational discrimination and to perceive the Müller-Lyer illusion. In Experiment 1, dogs were trained to discriminate line lengths using a two-alternative forced choice procedure on a touchscreen. Upon learning the discrimination, dogs’ generalization to novel exemplars and the threshold of their abilities were tested. In the second experiment, dogs were presented with the Müller-Lyer illusion as test trials, alongside additional test trials that controlled for overall stimulus size. Dogs appeared to perceive the illusion; however, control trials revealed that they were using global size to solve the task. Experiment 3 presented modified stimuli that have been known to enhance perception of the illusion in other species. However, the dogs’ performance remained the same. These findings reveal evidence of relational learning in dogs. However, their failure to perceive the illusion emphasizes the importance of using a full array of control trials when examining these paradigms, and it suggests that visual acuity may play a crucial role in this perceptual phenomenon.     

Teachers’ perceptions of students’ additional support needs: in the eye of the beholder?

Nowadays, teachers are regarded as key players in the process of identifying and catering to students’ additional support needs within mainstream primary classrooms. However, teachers’ professional judgements regarding students with special needs have been found to be contextually influenced (e.g. by school context, student population, level of achievement). It is unclear whether teachers’ perceptions of their students’ actual support needs are also influenced by their personal and professional characteristics. Hence, a better understanding of the value of teachers’ perceptions regarding students’ needs is needed. Therefore, this study explored perceptions of 109 Dutch mainstream primary teachers regarding four dimensions of students’ additional support. It addressed whether these teacher-perceived students’ needs are affected by teachers’ years of experience, level of training, personality traits and self-efficacy beliefs. It was found that teachers’ perceptions of students’ needs were relatively unbiased by their personal and professional characteristics.     

Student planners in school and out of school: who is managing whom?

This paper examines the use of student planners (agendas) with elementary school students. It asks how teachers, students and parents in two classrooms engage in the literacy practice of using student planners. A literacy object originally introduced to manage schoolwork in and out of school for students with learning difficulties, planners are now used widely in school districts across North America. In this cross‐case analysis, planners are shown to be used for a number of functions beyond organising students’ schoolwork. The student planners were tools through which teachers, parents and publishers extended their spheres of influence – objects used to manage others when an individual was not physically present to do so and objects used to gain entry to the classrooms and homes for particular purposes.     

The ordinary school – what is it?

In this paper we describe some of the complexities involved in the construction of a sample of ‘ordinary’ schools. We outline the policy context in England that produces pressures to resist ‘ordinariness’. The paper then explores two theoretical tools, fabrication and rhetoric, that are deployed in an analysis of some key artefacts of fabrication from schools in England. Through an examination of artefacts such as school brochures and websites, this paper asks whether there are any ‘ordinary’ schools in these performative times?     

Why is leading school improvement such a difficult process?

Leading meaningful school improvement and reform has proven to be a difficult process. This article looks at some of the interactive, contextual variables that lend to the complexity of this challenge. These include complexities inherent in schools, in change processes and in the leadership role itself.     

How Real is the Quantum World?

The three main theses proposed by Mario Bunge are discussed. The peculiar nature of quantum discreteness is argued in disagreement with his first one. General agreement, with some important distinctions, is expressed instead with his other two theses about the peculiar nature of the properties of quantum objects, and the realist interpretation of Quantum Theory. The notion of context dependent, but objectively definable, properties, and the redefinition of Natural Laws as general constraints allowing the occurrence of random events not conflicting with them are however needed in order to qualify more precisely the meaning of terms such as properties and realism. A new probabilistic formulation of Quantum Mechanics in phase space, which eliminates, together with the unphysical concept of probability waves, also the main paradoxical features of the conventional theory, is finally briefly sketched.     

In the eye of the beholder: Do adult students’ achievement goal orientation profiles predict their perceptions of instruction and studying?

The purpose of this study was to examine how adult students’ perceptions of their learning environment vary as a function of their achievement goal orientations. Study 1 (n = 196) reports the development of a questionnaire that focuses on aspects of instruction presumably linked to student motivation. In Study 2, students (n = 167) were classified into groups according to their goal orientation profiles, and then compared in terms of their evaluations of the learning environment and their relation to it. Students with different motivational profiles perceived the learning environment somewhat differently, with most differences reflecting the students’ view of their own role in studying. The findings will be discussed in terms of how personal and contextual factors contribute to the development of individuals’ motivation.     

The ‘outdoor school’ as a school improvement process: empirical results from the perspective of teachers in Germany

This paper focuses on school improvement processes in the context of weekly curricular-based teaching and learning activities outside the classroom – known as Draußenschule or ‘outdoor school’ – in three German primary schools. Qualitative interviews were conducted with three teachers two years after implementing the ‘outdoor school’. The teachers’ experiences show that the implementation and (ongoing) development of an outdoor school affects (1) teaching as such; (2) the school staff, and (3) the entire school as an organisation. The three areas are interlinked in different ways and the school improvement process cannot be approached from the perspective of any one area alone.     

The diagnosis of LD in English learners: is it nondiscriminatory?

This study examined the operationalization of one of the key reforms initiated by the Education for All Handicapped Children Act of 1975 (U.S. Congress, 1975) and continued through the 2004 reauthorization of the Individuals with Disabilities Education Act (U.S. Congress, 2004)--namely, nondiscriminatory assessment. The original and current specifications in federal law require that tests be selected and administered so as not to be racially, culturally, or sexually discriminatory. The specific dimensions studied here pertain to the nondiscriminatory diagnosis of learning disabilities (LD) in English learners. A checklist of legal and professional guidelines for making assessments of English learners was used to evaluate 19 psychological reports made on English learners as part of the assessment process for special education eligibility in a small, urban elementary school district in California. The results of this study present a fairly compelling profile of how the writers of psychological reports--school psychologists--do not use extant legal or professional guidelines for making nondiscriminatory assessments of bilingual children.     

Teaching in the age of accountability: restrained by school culture?

In this paper, we explore how ‘teaching communication’ in the classroom is connected to school culture. In the age of accountability, the outcome focus force to the forefront, a ‘blame game’ which either blames students’ achievements on the teachers and teacher education, or the students and their socio-economic background. We argue that to succeed with teaching and learning is dependent on the school culture more than the single teacher or the students’ backgrounds. School culture is understood as attitudes, communication, student focus and engagement. Teaching communication in this paper is studied as teachers’ and students’ talk about subject matter in whole-class teaching. We explore how different school cultures give students different opportunities to experience meaning from teaching communication. The perspective on meaning is derived from Bildung-centred didactics. By using qualitative comparative case method in Norwegian Lower Secondary schools, we find three different types of ‘teaching communication’ typical for different school cultures: ‘Dialogic teaching communication’, ‘storytelling teaching communication’ and ‘reproducing teaching communication’. The school culture with the ‘dialogic’ variant is characterized by trust and reciprocity, making students’ experiencing meaning a possibility.     

‘Out of the Box’ leadership: action research towards school improvement

The contribution of Action Research (AR) to school improvement is well-documented. This study records the accounts of two primary school leaders, involved in AR projects that focused on the development of students’ oral communication skills. Drawing data from diaries with fieldnotes and systematic reflections, the study presents leaders’ experiences, as they translated feedback into modifications and redefinitions to bring about change. Despite difficulties encountered, the leaders acknowledged the value of collaborative school-based enquiry for teachers, students and themselves, mainly reflecting notions of catalytic and democratic validity. The paper highlights that AR as a tool for individual and school improvement, can enhance understandings of school performance and empower participants to focus on school outcomes in an educational context that does not implement accountability measures. AR can certainly help principals in Cyprus reconceptualise and rediscover their pedagogical role as instructional leaders to improve teaching and learning. Yet, to address outcome and process validity, the paper argues about the need for evaluative tools.     

Engineering design in the classroom: Is it good science education or is it revolting?

The changing emphasis of science education today includes a shift from a narrowly disciplinary view of science to a more socially and technologically situated perspective. This article reports on the implementation of engineering design projects in about two dozen U. S. secondary science classrooms, following an inservice professional development course conducted at a university engineering college. Using data from an evaluation of the project and three sociological themes—secrecy and ownership, social persuasion and the status of facts, and the relationship between money and science—I argue that technological design projects provide a sociologically fruitful approach for teaching new themes in science education. However, teachers must rethink the nature of their subject matter, something that may be difficult if their training was disciplinary in emphasis.
