Inquiry Lesson

This paper deals with how scientific contents related to the water cycle are expressed (6th grade) as well as the role that the teacher´s questions play during an inquiry-based lesson. The research questions of the study were: What scientific concepts are constructed by students and teacher? What kind of questions uses the pre-service teacher in order to guide the thought of students? The employed methodology is based on video-analysis, being the data source a 1 hour video recording. Difficulties are perceived when students try to explain the scientific concepts (evaporation and condensation) in the context of the water cycle. The video allowed us to observe the difficulty involved in making knowledge move forward as the session progresses.

Digital storytelling is a relatively fast-growing currency in many classrooms, particularly in the context of TEYL. In the past decade, numerous studies have captured this trend as listed in the major research databases. Regardless of the rich documentation, it is rare to find an investigation on the area from the perspective of narrative inquiry. This study attempts to fill the methodological gap and seeks to answer two research questions: (1) How does the implementation of digital storytelling in Teaching English to Young Learners (TEYL)? (2) How do the students respond to the use of digital storytelling? Conducted in an elementary school in Surakarta, this study depicts the story of a pre-service teacher when he used digital storytelling to teach English to fifth graders of an elementary school in Surakarta, Indonesia. The data of this study were obtained through video recording, field notes, and students’ reflection. The study reveals that digital storytelling can be delivered through various models and is open to combinations of technology. One model applied in this study has the following general steps: an opening, focusing on the story, further exercises, and closing. Activity which including the interaction between the teacher and students such as QnA observably preferred by the students.

Purpose: This study was carried out in a cork company and its purpose was to observe and analyze the practices and methods used during the tools/series change moments and to propose improvements and alternatives to these same procedures so that the time needed to carry out the setup is reduced by 15% in both lines. Methodology/Approach:The methodology included the following phases: 1st - historical data collection and setup video recording, 2nd - footage analysis and conduction of informal interviews with employees, 3rd - flow, Gantt, and spaghetti charts creation and making of an action plan based on the waste and improvement opportunities identified in video analysis, 4th - validation with the line workers of the new operating mode created with the Single Minute Exchange of Dies (SMED) tool and communication to the Maintenance department about their role in this project, 5th - making and placement of plasticized cards on the cutting lines to ensure that new operating mode is followed and carrying out the actions identified in the action plan. Findings: Throughout this project using observations, video recording and its subsequent analysis, as well as interviews to the workers operating in the line, it was found the existence of several actions carried out by them during the setups which did not add value to the product, lack of adequate tools for the work to be performed and lack of work tools in general Research Limitation/implication: The study was limited by the lines and products under study and by the duration of the curricular internship, which was about five months. Originality/Value of paper: The article demonstrates the added value in terms of product quality and production output rate that SMED methodology can bring to companies that adopt the lean philosophy and in particular this continuous improvement tool.

The purpose of this chapter is to show how information communication technologies (ICT) facilitated communication between primary pre-service teachers that enabled a ‘community of learners’ to develop children’s scientific literacy. Cultural-historical theory was used to frame a study that sought to explicitly go beyond thinking as being individualistic, and to show how thinking can also be considered as a collective endeavour. In particular the study identifies how thinking forms part of a ‘community of learners’ both virtually and in reality within classrooms. The study was able to make visible child and pre-service teacher interactional sequences that brought together everyday concepts and scientific concepts to support concept formation in science. The study revealed the dialectical relations between everyday concepts and scientific concepts for moving from an interpsychological level to an intrapsychological level. The collective, rather than the individual orientation, made such a perspective possible. Importantly, the use of ICTs facilitated communication between members of the collective.

Abstract Nowadays, in many Italian and European universities, teachers’ training includes one or more examinations related to new didactic methodologies and practices. The topic of this paper is how it is possible to realize a new video analysis laboratory as a didactic and research “tool” for teachers’ training at the University of Salerno that can support teaching–learning process for new teachers. The main idea of this project is to design and implement a mobile video analysis laboratory for video recording real or simulated didactic activities. In addition, the concept that drives this research is to develop a “plug-and-play” laboratory that can be installed everywhere in less than 15 minutes by everybody. This laboratory is already designed and tested and is composed of five cameras, a control room software and an open source video analysis software.

Resumo: Discutimos percepções sobre adolescência de um grupo de professores de ciências que frequentaram um curso de extensão. Para tanto, realizamos uma pesquisa qualitativa em educação com foco no cotidiano escolar que incluiu como instrumentos de pesquisa: material proveniente de videogravação, produções dos professores e anotações da pesquisadora. Na análise, usamos algumas ideias de Moscovici para representações sociais. Constatamos percepções pouco divergentes em relação aos estereótipos de adolescentes difundidos socialmente, ainda que tenham ocorridos avanços (como o reconhecimento de características dos adolescentes, das referências etc.) em direção aos conceitos científicos trabalhados no curso. Esperamos maior atenção sobre adolescência na formação de professores de ciências, posto que, possivelmente, essas percepções estão presentes na forma com que os professores exercem seu trabalho.Palavras-chave: Adolescência; Ensino de Ciências; Formação Continuada de Professores de Ciências Perceptions about adolescence by science teachersAbstract: We discussed perceptions about adolescence of a Science teachers group who attended an extension course. Although, we conducted a qualitative research in education with a focus on school routine, which included as research tools: video recording material, teachers productions and the researcher`s notes. In this analysis, we used some of Moscovici`s ideas for social representations. We found slightly divergent perceptions in relation to adolescents stereotypes that are socially disseminated. Even though advances have occurred (such as the recognition of adolescents characteristics, references and etc.) towards the scientific concepts worked on that course. We expect greater attention on adolescence in the training of Science teachers, since these perceptions are present in the way that teachers exercise their work.Keywords: Adolescence; Science Teaching; Continuing Education of Science Teachers.

Research Questions

This research was motivated by the rampant of batik female workers who worked with the Putting Out System (POS) and were marginalized in Pekalongan City. This study was aimed to answer the research questions: what was the marginalization form of women workers through the wage system and division of labor in the production chain based on POS was; the actors who were involved in the process; what factors caused it; and what was implications for women workers, their family and bosses inside production process as well as outside the production process. In-depth interview and observation were used to investigate data. Triangulation of data source and investigating method were also used to validate the investigated data. In addition, Interactive model was used to analyze. The results were: (1) the actors who played a role in the process of marginalization of women workers in Pekalongan batik is the boss, makloon, religious elite (Kyai / Ustazd - ah), and the state; (2) the cause root of that marginalization was manipulated by patriarchal and capitalism ideology; and (3) the implication of that marginalization for woman workers inside production process was that they were positioned as a production machine to make a profit. While the implications outside the production process, they still lived in poverty.

ABSTRACTDigitization of video recordings often requires the laborious procedure of manually clicking points of interest on individual video frames. Here, we present progressive tracking, a procedure that facilitates manual digitization of markerless videos. In contrast to existing software, it allows the user to follow points of interest with a cursor in the progressing video, without the need to click. To compare the performance of progressive tracking with the conventional frame-wise tracking, we quantified speed and accuracy of both methods, testing two different input devices (mouse and stylus pen). We show that progressive tracking can be twice as fast as frame-wise tracking while maintaining accuracy, given that playback speed is controlled. Using a stylus pen can increase frame-wise tracking speed. The complementary application of the progressive and frame-wise mode is exemplified on a realistic video recording. This study reveals that progressive tracking can vastly facilitate video analysis in experimental research.
