The Practice of Reading, Writing Papers and Linguistic Analysis in Teaching Portuguese: A Proposal for the Organization of Everyday School Life from the Perspective of Multiliteracies

This paper aims to reflect on the teaching of Portuguese language in the context of twenty-first century, taking as its starting point the proposal of multiliteracies. We propose to discuss the applicability of genres in the classroom as a condition to ensure the construction of fundamental knowledge to social practices of language. For this, we rely on recent studies on the possibilities that the genre can bring to practice reading, writing papers, and linguistic analysis. We intend, therefore, to assist the planning of teachers who still find themselves unsure on curricula that suggest what they have to do, but did not say how. Understand the reason why this work is another contribution to the teaching of Portuguese in the final years of elementary school and high school bringing out a space for discussion about what needs to be taught and some teaching procedures that favor the democratization of school and interaction linguistics. Curricular innovations and new ways of thinking about teaching and learning of mother tongue are already part of the reflections of most professionals, but there is still an open field to think of more effective alternatives through multimodality an interactionist conception of language.

2020: A New Era of Sign Language Literature

 Summary: Sign language is the primary daily language of many Deaf people, yet sign language is not always included as a part of Deaf Education. Teachers of the Deaf in France in the late 1700s and early 1800s established using sign language in the classroom and yet generations later educators chose to revert back to oralism, not including any sign language when teaching Deaf children. And the trend continues to this day. Researchers in the 1960s, 70s and 80s proved that sign languages are natural languages, and yet this fact did not change the difficulties schools still have in reassuring parents and administrators that the Deaf students will learn to communicate, read and write a sign language as with your fellow listeners regarding oral languages that speak. Now, in the 21st century most educators and researchers are aware that sign languages are sophisticated languages with grammar, syntax and large vocabularies. Yet accepting sign languages as written languages has taken longer. Those who support the idea of writing sign languages feel that the availability of written literature and poetry in sign languages will lead to improved literacy in oral languages and in the long run, increase acceptance by the hearing world. Showing that sign languages have a written form helps establish sign languages as foreign languages in schools. With the advent of the internet and social media, writing sign languages is spreading quickly. The year 2020 is the beginning of a new era of sign language literature.Keywords: Sign Language; Literature; SignWriting; Deaf; Education.

New dimeric supramolecular structure of mixed (phthalocyaninato)(porphyrinato)-europium(III) sandwiches : preparation and spectroscopic characteristics

The mixed double-decker Eu\[Pc(15C5)4](TPP) (1) was obtained by base-catalysed tetramerisation of 4,5-dicyanobenzo-15-crown-5 using the half-sandwich complex Eu(TPP)(acac) (acac = acetylacetonate), generated in situ, as the template. For comparative studies, the mixed triple-decker complexes Eu2\[Pc(15C5)4](TPP)2 (2) and Eu2\[Pc(15C5)4]2(TPP) (3) were also synthesised by the raise-by-one-story method. These mixed ring sandwich complexes were characterised by various spectroscopic methods. Up to four one-electron oxidations and two one-electron reductions were revealed by cyclic voltammetry (CV) and differential pulse voltammetry (DPV). As shown by electronic absorption and infrared spectroscopy, supramolecular dimers (SM1 and SM3) were formed from the corresponding double-decker 1 and triple-decker 3 in the presence of potassium ions in MeOH/CHCl3.

Disorderly categories in picture postcards from colonial Papua and New Guinea

At the turn of the century in Melbourne, a notice typed on the verso of a postcard stated that the South Yarra Baptist Young Men's class was meeting on the following Sunday at 2.45 p.m. The card, published in the United Kingdom, was numbered 51828 in the Valentine series of Papuan postcards.1 The image, a photograph of Hanuabada village taken in the early 1880s, and the text, written early in 1900, are contradictory and constitute separate realms of evidence that invite a renegotiation of meaning, analysis, and interpretation of the relationships between images, tourism, colonial rule, and ethnographic knowing. The visual evidence suggests the postcard may have played an ethnographic, educative role in the public understanding of Papua, which had just become an Australian Territory and was not yet well known. It is also suggestive of educative roles related to mission endeavours, subimperialist ambitions and the new tourist traffic through the ports of Port Moresby, Samarai, and Rabaul.

A new low temperature synthesis route of fraipontite (Zn,Al)3(Si,Al)2O5(OH)4

A low temperature synthesis method based on the decomposition of urea at 90°C in water has been developed to synthesise fraipontite. This material is characterised by a basal reflection 001 at 7.44 Å. The trioctahedral nature of the fraipontite is shown by the presence of a 06l band around 1.54 Å, while a minor band around 1.51 Å indicates some cation ordering between Zn and Al resulting in Al-rich areas with a more dioctahedral nature. TEM and IR indicate that no separate kaolinite phase is present. An increase in the Al content however, did result in the formation of some SiO2 in the form of quartz. Minor impurities of carbonate salts were observed during the synthesis caused by to the formation of CO32- during the decomposition of urea.

The role of microcomputer-based laboratory display in supporting the construction of new understanding in kinematics

Teachers' failure to utilise MBL activities more widely may be due to not recognising their capacity to transform the nature of laboratory activities to be more consistent with contemporary constructivist theories of learning. This research aimed to increase understanding of how MBL activities specifically designed to be consistent with a constructivist theory of learning support or constrain student construction of understanding. The first author conducted the research with his Year 11 physics class of 29 students. Dyads completed nine tasks relating to kinematics using a Predict-Observe-Explain format. Data sources included video and audio recordings of students and teacher during four 70-minute sessions, students' display graphs and written notes, semi-structured student interviews, and the teacher's journal. The study identifies the actors and describes the patterns of interactions in the MBL. Analysis of students' discourse and actions identified many instances where students' initial understanding of kinematics were mediated in multiple ways. Students invented numerous techniques for manipulating data in the service of their emerging understanding. The findings are presented as eight assertions. Recommendations are made for developing pedagogical strategies incorporating MBL activities which will likely catalyse student construction of understanding.

Foil rolling : a new interpretation of experimental results

This paper explores a new interpretation of experiments on foil rolling. The assumption that the roll remains convex is relaxed so that the strip profile may become concave, or thicken in the roll gap. However, we conjecture that the concave profile is associated with phenomena which occur after the rolls have stopped. We argue that the yield criterion must be satisfied in a nonconventional manner if such a phenomenon is caused plastically. Finite element analysis on an extrusion problem appears to confirm this conjecture.
