title: Effects of Marketing Channels and Season on Weight and Quality Grades Classification According to Gulf Cooperation Council Standardization Organization standard of Fresh Commercial Table Eggs Marketed in Riyadh City (Saudi Arabia)

description: ABSTRACT The present study aimed to assess egg quality by identifying quality grades and weight class classification of fresh commercial Table eggs marketed in the city of Riyadh during winter and the summer seasons, and comparing the measured traits rendering to the Gulf Cooperation Council Standardization Organization. A total of 480 eggs were purchased from two different channels of marketing, four supermarkets and four grocery stores located in different areas of the city of Riyadh during summer and the winter seasons. It appeared from the outcomes that the eggs purchased from the supermarkets had significantly higher AA and A Haugh units, albumin pH and AA air cell grades and medium egg weight class, and they also had lower B and C Haugh units, albumen pH, A and B air cell depth grades, and very large, large and small eggs weight classes percentages than those obtained from grocery stores. Over and above, the eggs obtained in the winter had significantly higher AA and A Haugh unit, albumin pH, AA air cell depth grades percentages, very large and large egg weight class percentages, and had less B and C Haugh unit and albumen pH and B air cell depth grades and small weight class percentages than those obtained in the summer. In summary, marketing channels and season play a significant role in affecting quality traits of Table eggs, also those procured from supermarkets and in the winter presented better quality than those obtained from groceries or in the summer, respectively. Grocery stores or small shops have to follow proper handling and storage conditions requirements to maintain good quality of Table eggs, especially in the summer season.

title: Manipulable materials and engagement of students in math classes involving topics of geometry

description: Abstract In this paper, we analyze the mutual engagement of students in the development of mathematics lessons that addressed topics of geometry, in which manipulative materials were used. To understand the object of study, we used the Situated Learning Perspective according to Jean Lave and Etienne Wenger. Data were collected through observation, interviews and documents (student records during the tasks). The results suggest that the practical knowledge is changeable according to changes occurring in the forms of engagement, and featuring other broader engagement. Furthermore, we presented the following situational engagements: the engagement of students in primary contact with the elements of manipulative materials, the involvement of students cutting out squares according to the rules given, the association of engagement in a zero angle to the starting position of the sticks, and the involvement in the association with the sides of the square and the sides of the triangle.

title: Teaching of religion in the State of Rio de Janeiro public schools: implications to science and biology teaching

description: Abstract: This work aims to investigate the implications and challenges to Science and Biology teaching that arose from the implementation of a State law in Rio de Janeiro, Brazil, which made confessional religious teaching mandatory in public schools. As a source, we have employed the readers' letters section in the newspaper O Globo, supplemented by other media statements and academic works. The controversy of religious teaching in Brazilian public schools shows to be associated with new elements, including disputes related not only to citizenship and religious freedom, but also to the debate between creationist and evolutionist views, a relatively new confrontation in Brazil with a huge growth potential. This setting comes from new alliances between religious groups disputing in the public space against defenders of secularity. On face of it, we reinforce the importance of promoting scientific dissemination and the philosophical demarcation of Science in the classroom, with the special contributions of Philosophy and History.

title: Science and theater: a study of the performing Arts as a strategy for Science communication in museums

description: Abstract: Theater has been used as a strategy for science education and communication in museums. In this article, we analyze two theatrical activities offered by the Museum of Science and Life, located at Duque de Caxias (RJ). Based on interviews and questionnaires, we found that the visitors consulted are familiar with the theater, although they are not frequent visitors. Those with less access to cultural programs, previous involvement with the topics addressed and whose children engaged in the activity tended to receive it positively. When the activity did not attract the child in the group or the expectation it raised was different from that expected, the tendency was dissatisfaction. Regardless of the opinions gathered, we observed that the activities aroused public reactions that would be difficult to provoke by traditional museum activities. Thus, we advocate the interaction between science and theater as a differentiated strategy for science education and communication.

title: The use of information and communication technologies in Chemistry teaching and the semiotics aspects involved in the information interpretation through web access

description: Abstract: The use of information and communication technologies (ICT) results in a transformation in the teaching-learning process, highlighting the relevance of the information for the use of ICT in the classroom. This paper, part of a doctorate degree research, discusses the information access and the use of ICT in chemistry teaching and the semiotic aspects involved in the interpretation of information to verify the learning process. The research took place in a public school and investigated how the students interpreted and manipulated information obtained through the web. It also investigated how the pupils made the abstract correlation among semiotics signs in order to formulate representative reasoning about absent objects. It was verified that the information accessed in an autonomous way and manipulated by the students was insufficient to learning development, showing that teacher mediation is fundamental for the use of ICT with the purpose of making significant use of information through internet access.

title: Science teachers' continuing training using Aquaponics as a didactic tool

description: Abstract: This study reports on a study that focused on the continuing education of secondary school teachers, trying to understand how aquaponics could support pedagogical activities, emphasizing the development of science. Results show the difficulty in applying interdisciplinarity to integrated projects at school, due to the heavy workload for teachers, and contents that they should account for, which leads to a lack of time to plan and carry out activities together. This may have an effect on students' lack of interest and indiscipline. However, teachers' final evaluations using the system were positive, thus reflecting the importance of activities that differ from everyday classroom routines. We realize that these diverse classes hold students' attention and motivate them to interact with teachers.

title: Representational Tensions in students' Discourses while completing experimental Physics activities

description: Abstract: Based on the theory of codes by Basil Bernstein, Andréia de Oliveira presents the concept of Tension in Discourses to designate the discontinuities between the different discourses present in educational practice, characterized by contradictions, ruptures and dilemmas that are generated by spaces that separate the categories of specialized discourses. In this paper, we analyze the representational tensions manifested in students' discourses when they performed experimental activities in a didactic physics laboratory. These tensions are characterized by showing the contradictions, ruptures, dilemmas, conflicts and uncertainties when data coming from experimental activities are contrasted with the concepts present in theoretical classes, thus causing an isolation in the internal discourse about physics to become evident. We found that the students revealed these tensions at the moments when they represented the measures with their uncertainties, when they transformed units of measurement and their uncertainties, and when they registered the number of decimal places and of significant algorithms for the measurements and their uncertainties.

title: The planning of Chemistry teaching sequences based on the Topological Model of Teaching: potentialities of the EAR (Elaboration, Application and Re-elaboration) process on pre-service teacher education

description: Abstract: This paper aims to evaluate the influence of the Elaboration, Application and Re-elaboration (EAR) process on the development of pre-service chemistry teachers’ ability to plan teaching sequences. This study consists of document analysis using two different versions of chemistry teaching sequences (TS) produced by pre-service chemistry teachers. The document analysis was carried out based on the Topological Model of Teaching and on a standard tool for TS validation. The data show significant advances in the redesigned TS, which became more cohesive as regards problem-solving, thus fulfilling the role of a structuring element throughout all teaching activities. This gain can be attributed to the assessment of TS from different perspectives, inserted in this virtuous cycle of the EAR movement, which is fundamental to relate specific contents to pedagogical theories, approximating the theoretical planning and concrete professional practice, as well as developing an investigative attitude about teaching activities.

title: O Show da Luna as a Mediating Genre for Scientific Education

description: Abstract: This article reports on documentary research carried out in the field of interdisciplinary studies in Applied Linguistics. The research object is the animation O Show da Luna, categorized as an emerging genre: educational scientific cartoon. The general objective was to discuss science representations and to analyze the pedagogical functions that animation can assume to mediate scientific education practices for children, especially covering the humanities as legitimate science. The focus was on the science of language, which permeates all other scientific areas by building them, mediating their productions and communications. For this reason, the research also resulted in the proposal of alternative scripts for the animation, aiming at education through research in Portuguese Language in early childhood education.
