Preservice Elementary Teachers’ Beliefs About Science Teaching

In this study, a Beliefs About Teaching (BAT) scale was created to examine preservice elementary science teachers’ self-reported comfort level with both traditional and reform-based teaching methods, assessment techniques, classroom management techniques, and science content. Participants included 166 preservice teachers from three different US universities. Analyses revealed significant correlations among participants’ confidence level with assessment techniques, classroom management, teaching methods, and science content and number of science methods and science content courses taken. A significant difference was observed among the students enrolled at each university. Overall, study participants felt more comfortable teaching biology concepts than teaching chemistry concepts, physics concepts, or both.     

Learning About Other People’s Families

While the call for teacher education students to learn about their students’ family and community lives remains urgent and compelling, educating teachers about the Other is tricky business. In this article I discuss the use of two performed ethnographies, Harriet’s House and Ana’s Shadow, to provide opportunities for teachers to learn about Other people’s families in ways that work against presenting a singular, dominant narrative of the Other’s experiences and positioning Other students as experts. Although the outcomes from educating teachers about Other people’s families are unpredictable and do not always disrupt the prior, potentially harmful, knowledges teachers bring with them to teaching, I argue, along with Kevin Kumashiro, that ongoing labour to stop the repetition of harmful knowledges is important anti-oppressive educational work.     

It’s About Making Surfaces Invisible

Antireflection is an essential requirement for certain optoelectronic devices. Antireflective surfaces can be generated by different methods. One method mimics the nanofeatures on the moth eye surface. This can be done by ‘soft lithography’ (SL), where nanofeatures are created on an elastomeric stamp. This stamp is then used for imprinting the pattern on other surfaces.     

Comparing conceptual text and documenting photos. Researching Outdoor Education in the Context of Reichwein’s Progressive Teaching and Rousseau’s Émile

ABSTRACT

This paper explores the historic ideas and practice of outdoor education, as developed in Jean Jacques Rousseau’s Émile, and realized by Adolf Reichwein's rural teaching practice. We aimed at developing a comprehensive research design, triangulating different qualitative data (text and photos). In the paper, we explore how the idea of place-based outdoor education unfolded in Rousseaús Émile, and how Adolf Reichwein, in rural Tiefensee, enacted the practice of place-based outdoor education. We also investigate how to correlate different types of qualitative data (conceptual text and documentary photos). We show that it is possible to develop a research language, revealing how a philosophy of education can be enacted as educational practice, and our analysis demonstrates that Rousseaús and Reichwein’s works functioned as precursors for outdoor education and educational concepts, that activate the cognitive, affective, and motoric domains.     

Teachers’ Beliefs About Grading Practices and a Constructivist Approach to Teaching

We examined novice teachers’ beliefs about grading and constructivist teaching approaches. Adapting an existing instrument designed to assess preservice teachers’ grading beliefs that deviate from recommended practices, we administered the Survey of Grading Beliefs to 203 inservice teachers. Exploratory factor analysis resulted in a 3-factor model with a structure similar to that found in prior research; differences between the 2 samples were noted. Teachers who endorsed grading beliefs characterized as “academic enabling” tended to endorse constructivist teaching approaches. To better understand the underlying reasoning of the academic enabling factor, we conducted qualitative research with 6 additional teachers. Results revealed that teachers’ reasons for grading judgments were strategic, analytical, and thoughtful, not haphazard. This study provides empirical evidence about the nature of novice teachers’ beliefs about grading, how they relate to constructivist teaching beliefs, and how they may compare to the beliefs of preservice teachers.     

What Can Be Learned from Computer Modeling? Comparing Expository and Modeling Approaches to Teaching Dynamic Systems Behavior

Computer modeling has been widely promoted as a means to attain higher order learning outcomes. Substantiating these benefits, however, has been problematic due to a lack of proper assessment tools. In this study, we compared computer modeling with expository instruction, using a tailored assessment designed to reveal the benefits of either mode of instruction. The assessment addresses proficiency in declarative knowledge, application, construction, and evaluation. The subscales differentiate between simple and complex structure. The learning task concerns the dynamics of global warming. We found that, for complex tasks, the modeling group outperformed the expository group on declarative knowledge and on evaluating complex models and data. No differences were found with regard to the application of knowledge or the creation of models. These results confirmed that modeling and direct instruction lead to qualitatively different learning outcomes, and that these two modes of instruction cannot be compared on a single “effectiveness measure”.     

Students’ Perception of Risk About Nanotechnology After an SAQ Teaching Strategy

We experimented with teaching nanotechnology in high school within the perspective of citizenship education in science by involving experts in nanotechnology, education, ethics and philosophy. After training, the students debated a Socially Acute Question (SAQ) that they elaborated during the various phases of instruction. The field of SAQs represents a French orientation for the teaching of SocioScientific Issues. We analyzed the interactions of students in the debate to determine their risk perception on nanotechnology. We compared and put their arguments into perspective using various analytical frameworks. We observed two contrasting argumentative tendencies: one reflecting a positivist view that involved an individualistic use of nanotechnology and science and one carrying a critical and humanistic vision of the use of nanotechnology and science.     

Cooperative Learning in China’s College English Teaching

Maxwell’s demon and the second law of thermodynamics

A century and a half ago, Maxwell introduced a thought experiment to illustrate the difficulties which arise in trying to apply the second law of thermodynamics at the level of molecules. He imagined an entity (since personified as ‘Mawell’s demon’) which could sort molecules into hot and cold and thereby create differences of temperature spontaneously, apparently violating the second law. This topic has fascinated physicists and has generated much discussion and many new ideas, which this article goes over. Particularly interesting is the insight given by deeper analysis of the experiment. This brings out the relation between entropy and information, and the role of irreversibility in computing as we understand it — topics still under discussion today.     

Teaching: in light of Noel Gough’s and Ajay Sharma’s articles

In their articles, Ajay Sharma (Cult Stud Sci Educ, doi: 10.1007/s11422-017-9835-z, 2017) and Noel Gough (Cult Stud Sci Educ, doi: 10.1007/s11422-017-9834-0, 2017) shed light on the impact neoliberalism has on the teaching of science and suggest ways to ensure that science education remains critical and socially equitable. In this paper, I illustrate how their proposals influenced my instructional choices during the fall of 2016 in a course entitled Epistemology and Education.     

Evaluation of Three Primary Teachers’ Approaches to Teaching Scientific Concepts in Persuasive Ways

The research set out in this paper seeks to develop pedagogical knowledge regarding how persuasive teaching approaches can be developed in primary science classrooms. To achieve this, the paper examines three case studies in which the teachers have been charged to develop and implement teaching strategies designed to persuade their children of the usefulness and validity of target scientific concepts. The analysis probes the teachers’ choice of contexts and patterns of discourse using criteria drawn from the socio‐cultural literature. Outcomes of the study exemplify how the teachers’ choices of learning contexts fail to emphasise the functionality of the target concepts, and as a consequence scant rewards are provided for the children to participate actively in conceptually rich discourse. The final part of the paper explores how the development of what the author calls theme‐specific plots could be used to help teachers to stage teaching and learning performances that emphasise the functionality of specific explanatory models.

Summer’s End and Sad Goodbyes: Children’s Picturebooks About Death and Dying

This article explores children’s picturebooks about death and grieving by considering both psychological and literary aspects. Two questions frame this analysis: How can picturebooks, particularly written for young children, support children’s grief when someone dies? How do the illustrations and text of picture books express and convey the aesthetic and emotional experience of loss? Using both psychological research on children’s grief reactions and literary analysis of picturebooks, this paper reviews picturebooks that have been published on the topic of death from 2001 to 2011 and then closely analyzes three books that span a range of topics and approaches to death. Findings indicate that children’s picturebooks convey important psychological and cultural issues through text and illustrations. Furthermore, understanding some of the psychological and literary features of children’s picturebooks that address death and grieving can help educators to provide support and understanding for children when they experience loss.
