Is Teacher Accountability Possible? The Case of Norwegian High School Science

What influence does the teacher exercise over their students' learning outcomes? This study investigates the impact of teacher quality on student learning outcomes in science halfway through the first year of high school. A multiple‐measurement model estimates the potential impact of teacher influence on learning outcomes for 1,060 secondary school students (16‐year‐olds), as well as the influence on student engagement, motivation, and self‐discipline. Teacher quality has a very weak effect on student learning outcomes. However, teacher quality seems to influence student motivation and self‐discipline to a significantly larger extent. Further, there is an indirect effect of teacher quality on learning outcomes in science via student engagement, motivation, and self‐discipline. Holding the science teacher accountable for pupils' learning outcomes is highly problematic.     

What Does Distributed Cognition Tell Us about Student Learning of Science?

This paper reports multi-layered analyses of student learning in a science classroom using the theoretical lens of Distributed Cognition (Hollan et al. 1999; Hutchins 1995). Building on the insights generated from previous research employing Distributed Cognition, the particular focus of this study has been placed on the “public space of interaction” (Alac and Hutchins 2004, p. 639) that includes both participants’ interaction with each other and their interaction with artefacts in their environment. In this paper, a lesson from an Australian science classroom was examined in detail, in which a class of grade-seven students were investigating the scientific theme of gravity by designing pendulums. The video-stimulated post-lesson interviews with both the teacher and the student groups offered complementary accounts (Clarke 2001a) that assisted the interpretation of the classroom data. The findings of this study provide supporting evidence to demonstrate the capacity of Distributed Cognition for advancing our understanding of the nature of learning in science classrooms.

What Does Wiki Reveal About the Knowledge Processing Strategies of School Pupils?

On the basis of one teaching project carried out in a school, this article discusses collaborative writing in wiki platforms. It aims to find out what wiki reveals about pupils’ knowledge construction, creation, and division and their collaborative writing skills. In this project, wiki is treated as a useful tool for analyzing these processes because it gives us the possibility of studying those elements and stages of educative writing that are normally hidden from the teacher or researcher’s eye. Also, it shows us the interaction between pupils. The theoretical background of the project lies in collaborative writing and writing research.     

The Progression of Prospective Teachers’ Conceptions of School Science Content

The purpose of the present work is to describe the progression in the conceptions of prospective primary teachers about school science content while they were participating in three teacher education courses following the same constructivist oriented strategy. The participants’ written output was analyzed in various categories—selection of content, types of content and their relationships, levels of complexity, and presentation of content to pupils. There was evidence for some progress in their conceptions of the content from a traditional view to another that we termed intermediate since it did not reach the vision that we consider to be the most complex. Finally, we present a General Itinerary of Progression on school content that could serve as a referent for initial teacher education.

What Kind of English Class Do You Like?

I hope I’ll have more chances to speak English in class,because we can learn English well only by using it.However,we have no such a chance at home.I hope the teacher will arrange all kinds of activities in class,such as dialogues,short plays,reading contests and so on.I don’t think it good for the teacher to talk all the time while the students take notes only.I think it necessary to learn some grammar.But we shouldn’t study grammatical rules in     

Time Constraints in the School Environment: What Does a Sleepy Student Tell Us?

ABSTRACT— In this article, we discuss school schedules and their implications in the context of chronobiological contemporary knowledge, arguing for the need to reconsider time planning in the school setting. We present anecdotal observations regarding chronobiological challenges imposed by the school system throughout different ages and discuss the effects of these schedules in terms of sleepiness and its deleterious consequences on learning, memory, and attention. Different settings (including urban vs. rural habitats) influence timing, which also depends on self-selected sleep schedules. Finally, we criticize the traditional view of a necessary strict stability of sleep–wake habits.     

The Impact of a Geospatial Technology-Supported Energy Curriculum on Middle School Students’ Science Achievement

Geospatial technologies are increasingly being integrated in science classrooms to foster learning. This study examined whether a Web-enhanced science inquiry curriculum supported by geospatial technologies promoted urban middle school students’ understanding of energy concepts. The participants included one science teacher and 108 eighth-grade students classified in three ability level tracks. Data were gathered through pre/posttest content knowledge assessments, daily classroom observations, and daily reflective meetings with the teacher. Findings indicated a significant increase in the energy content knowledge for all the students. Effect sizes were large for all three ability level tracks, with the middle and low track classes having larger effect sizes than the upper track class. Learners in all three tracks were highly engaged with the curriculum. Curriculum effectiveness and practical issues involved with using geospatial technologies to support science learning are discussed.     

What Do You Know about Alternative Energy? Development and Use of a Diagnostic Instrument for Upper Secondary School Science

The need for renewable and non-fossil fuels is now recognised by nations throughout the world. Consequently, an understanding of alternative energy is needed both in schools and in everyday life-long learning situations. This study developed a two-tier instrument to diagnose students' understanding and alternative conceptions about alternative energy in terms of: sources of alternative energy, greenhouse gas emission, as well as advantages, and disadvantages. Results obtained with Years 10 and 11 students (n?=?491) using the 12-item two-tier instrument (α?=?0.61) showed that students' understanding of alternative energy was low (M?=?7.03; SD?=?3.90). The 23 alternative conceptions about alternative energy sources that could be identified from the instrument are reported. The implications for teaching and learning about alternative energy and suggestions for further development and improvement of the instrument are presented.     

A Vocationalized School Science Curriculum?

This article is concerned with the meaning and legitimacy of the view that the secondary science curriculum can be given a vocational emphasis, and with a current attempt to create such a curriculum. Although this perspective on the science curriculum has a long history, in recent decades it has received little attention. This article examines recent research into the vocational and work‐related aspects of secondary school science, and the historical and policy background. Its empirical focus is a late secondary course with the title “Applied Science”, which was introduced into schools in England and Wales in 2002. It draws on the preliminary findings of a research study focusing on the origins and implementation of this course. Overall, the article provides an overview of the major issues and research agenda associated with the notion of a vocational or applied school science curriculum, focusing ultimately on the key issues of educational purpose, pedagogy, and status.     

The Role of Drawing in Young Children’s Construction of Science Concepts

It has been observed that many young children like making marks on paper and that they enjoy the activity. It is also known that children’s drawings are vehicles for expression and communication. Therefore, it would be logical and reasonable for teachers to incorporate children’s drawings into building science concepts. To demonstrate how drawings are utilized to help a child to acquire a science concept, the article first presents a vignette of an interaction between an adult and a 5-year-old boy, focusing on the science concept of the physical characteristics of a spider. It is then followed by several analytical explanations of how drawings build children’s understandings. Not only are the introduced strategies useful for one-on-one interactive communication, but also applicable to a small group of young children. The article ends with the specifics of how these strategies were applied to a group of four children in their acquisition of the science concept of the water cycle.     

Students’ Perceptions of High School Science: What has Changed Over the Last Decade?

This paper presents comparative questionnaire data from three different samples of Australian high school students in an attempt to see if anything has changed in relation to how they perceive the science they experience in the compulsory years of secondary school (grades 7–10). Questionnaire data were obtained from 1,585 high school students in 2011 and 2,016 students in 2005 and findings are compared with those reported in a national report (Goodrum et al. 2001). Results show significant increases in the frequency with which students report that their science teacher takes notice of their ideas and in the use of computers and the Internet. There have also been changes regarding the rapid provision of feedback, the use of understandable language by teachers and the contextualisation of the new work in terms of work already covered. Little appears to have changed, however, in relation to the teacher-directed pedagogies employed to teach science where there appears to be a higher incidence of copying notes and fewer opportunities for students to investigate topics in which they are interested. The findings suggest that while there have been some positive changes, there are still many students who indicate that the science they experience in secondary school is irrelevant to their everyday life and to their future. It seems that the curiosity and wonder one would hope is associated with studying science is missing for a large proportion of students. It is clear that further actions need to be undertaken to transform this continuing situation.

“What are you Representing?” Contesting Identities of Incarcerated Youth

This article explores how incarcerated youth and adult supervisors contest claims to identity via language of “representing”. Comparing how youth and adults “represent” in discussions of their own past and future selves sheds light on the constrained universe of discourse within which both groups work to express identities and on the basis of which we counsel, mentor, and educate young people. Acknowledging these constraints can contribute to understanding what I call exceptionalism—the idea that only exceptional poor and raced young men, through great personal effort and sacrifice, may resist the lure of the “street”. I conclude by discussing implications of this work for education and youth development work both inside and beyond the juvenile justice system as well as for research across lines of difference by committed “outsiders”.
