Teachers’ democratic assignment: a critical discourse analysis of teacher education policies in Ireland and Sweden

ABSTRACT

The needs of a globalized economy are rapidly changing what is legitimated as school knowledge and values, and calling up new understandings of teachers’ role in stimulating democratic spaces. We have termed this Teachers’ Democratic Assignment. We examine changing notions of teachers’ democratic assignment in Ireland and Sweden using a Critical Discourse Analysis. We tested our hypothesis that teachers’ democratic assignment has changed in unprecedented ways using an analysis of policy documents in teacher education. Our findings reported a substantive converging paradigm shift from a predominantly progressive (reconstructivist) curriculum discourse where democracy was seen as inextricably linked to everyday practice in the early years of this century, to a more essentialist (perennialist) discourse in recent times. The findings will have interest for a wider audience and have implications for the role of democracy in teacher education as well as the question of education as a social responsibility for a vibrant democracy.     

State-Dependent Memory in Infants

Why do infants remember some things and not others? Human infants frequently cycle through different states such as calm attentiveness, wakeful activity, and crying. Given that cognitive processes do not occur in isolation, such fluctuations in internal state might influence memory processing. In the present experiment, declarative memory in 9-month-old infants (N = 96) was heavily state dependent. Infants exhibited excellent retention of a deferred imitation task after a 15-min delay if their state at encoding was identical to their state at retrieval (e.g., calm). Infants failed to exhibit retention if their state at encoding was different from their state at retrieval (e.g., calm vs. animated). Infant memory processing depends on internal cues.     

Is the Confirmation Bias Bubble Larger Online? Pre-Election Confirmation Bias in Selective Exposure to Online versus Print Political Information

The Internet era has often been blamed for a predominant engagement with attitude-consistent information among citizens (labeled confirmation bias), which is thought to hurt political deliberation. This study offers the first rigorous evidence suggesting that online news fosters greater confirmation bias than traditional media. A 2 × 2 within-subjects experiment presented political articles, varying stance (conservative vs. liberal) and medium (online vs. print); selective exposure was logged or taped. Data were collected during the U.S. 2016 presidential primaries. As expected in the preelection context, partisans whose party was anticipated to lose the election (conservatives) did not exhibit confirmation bias. Liberals showed confirmation bias, but only online, suggesting print contexts reduce confirmation bias.     

Evaluation of serum glycoproteins in oral carcinoma

The present study was conducted on thirty untreated oral cancer patients proved by clinical and histopathological evidence and thirty healthy control subjects. The levels of glycoprotein-associated carbohydrates such as hexose, hexosamine, fucose and sialic acid were found to be elevated significantly as compared to control subjects. There was a progressive rise in these markers as the stages of oral cancer advanced.     

Science teachers' pedagogical content knowledge development during enactment of socioscientific curriculum materials

The purpose of this study is to provide insight into short-term professionalization of teachers regarding teaching socioscientific issues (SSI). The study aimed to capture the development of science teachers' pedagogical content knowledge (PCK) for SSI teaching by enacting specially designed SSI curriculum materials. The study also explores indicators of stronger and weaker development of PCK for SSI teaching. Thirty teachers from four countries (Cyprus, Israel, Norway, and Spain) used one module (30–60 min lesson) of SSI materials. The data were collected through: (a) lesson preparation form (PCK-before), (b) lesson reflection form (PCK-after), (c) lesson observation table (PCK-in-action). The data analysis was based on the PCK model of Magnusson, Krajcik, and Borko (1999). Strong development of PCK for SSI teaching includes “Strong interconnections between the PCK components,” “Understanding of students' difficulties in SSI learning,” “Suggesting appropriate instructional strategies,” and “Focusing equally on science content and SSI skills.” Our findings point to the importance of these aspects of PCK development for SSI teaching. We argue that when professional development programs and curriculum materials focus on developing these aspects, they will contribute to strong PCK development for SSI teaching. The findings regarding the development in the components of PCK for SSI provide compelling evidence that science teachers can develop aspects of their PCK for SSI with the use of a single module. Most of the teachers developed their knowledge about students' understanding of science and instructional strategies. The recognition of student difficulties made the teacher consider specific teaching strategies which are in line with the learning objectives. There is an evident link between the development of PCK in instructional strategies and students' understanding of science for SSI teaching.     

Communicative functions during the pre-grammatical stage: a case study / Las funciones comunicativas durante la etapa pregramatical: un estudio de caso

This study contributes empirical evidence regarding communicative functions in the pre-grammatical period. The aim was to explore these functions in child-adult dyadic interactions during what in language acquisition research has been called the two-word period. The study draws from the data corpus of a child 19–29 months old and the system of sign categories (gestures, non-verbal vocalizations, verbal vocalizations, uni- and bimodal compositions) developed by Rodríguez & Español. In order to study the communicative functions in this period, an observational code was developed in accordance with Strauss and Corbin’s Constant Comparative Method, which is suitable for encompassing the entire repertoire of a child’s sign use. The study in general allowed some functions absent in adult communication to be identified, and the qualitative analysis in particular revealed a use of semiotic resources that supports the idea of a cognitive processing structure common to gesture and word.     

Pedagogical Content Knowledge of Inquiry： An Instrument to Assess It and Its Application to High School In-Service Science Teachers

It is argued that the lack of consensus on what constitutes an inquiry-based approach makes the generalization about it difficult, because the concept is relatively unspecific and vague. This problem can partially be solved by constructing a set of activities promoted by inquiry, thus defining the inquiry objectives for classroom and laboratory teaching. Five high school and college Mexican teachers＇ PICK （pedagogical inquiry/content knowledge） was documented and assessed by means of Loughran, Mulhall and Berry＇s （2004） l-CoRe （inquiry content representation） developed by the authors through a proposal of a set of seven inquiry activities. They were also interviewed to construct the professional and pedagogical experience repertoires, a second tool by Loughran et al. （2004） to document PICK. It was observed that all teachers interviewed have used inquiry to modify their students＇ way of thinking, mainly through question posing. Some of them employed research as their main tool to promote scientific inquiry but others mentioned the lack of time to do it. It is interesting to notice that in spite of the fact that inquiry is out of the curriculum in M6xico, the teachers make use of it to improve their teaching practice. According to their answers, their actions in the classroom or the lab were classified within the three general approaches expressed by Lederman （2004）： implicit, historical and explicit. It is concluded that a given teacher cannot be classified exclusively in one of them, because in his/her activities one general approach overlaps the others. The authors conclude that Lederman＇s classification has to be taken into account as an orientation to characterize a given activity of one teacher, even though the same teacher may use another activity characterized by other general approach. That is, Lederman＇s classification applies to characterize activities, not persons
