Objectives: A possibility was shown to develop a pedagogical work for the initial years of Brazilian Elementary School based on pedagogical games, creating methodological theoretical subsidy to rethink strategic methods, resizing them in order to minimise the existing gap between ludic activities and everyday tasks carried out by students, spontaneously, and the work triggered in the classroom. Design: Cards were prepared for the game “Probability in Action”, called Questions (?), which are tasks based on problem situations with the objective of favouring the apprehension of contents and the development of probabilistic knowledge, having as theoretical support the Anthropological Theory of the Didactic - ATD by Yves Chevallard, consisting of two blocks, the practical and the theoretical. Setting and Participants: It was a theoretical work that presented a didactic and mathematical praxeology that exposed and explored, in detail, the practice and the probabilistic theory involved in the cards of the game “Probability in Action” focused on impossible random events in which it is associated with the solving tasks or problem situations. Data collection and analysis: Tasks associated with impossible random events were created and described using ATD, comprising type of tasks (T); techniques (τ) that solve tasks of this type; technology (θ) that justify the techniques and guarantee their validity, and, finally, the theory (Θ) that justifies the technology. This praxeological quartet is denoted [T, τ, θ, Θ], and the block [T, τ] is called practical-technical (praxis), or know-how block; and the block [θ, Θ] is called the technological-theoretical block (logos) or knowledge block. Results: In terms of the ATD, its use allowed identifying a set of praxeologies that made it possible to characterize both the probabilistic object and the didactic approach for such an object, and the praxeological organization was composed of four elements: 1) Task (T) and its subtasks (t), which was characterized by the action required by the problem situation proposed for the question cards in the game; 2) Technique (τ), identifying the way to perform the task and its subtasks; 3) Technology (θ), specified by the set of definitions, properties, axioms and theorems that justify the technique, that is, that the random phenomenon refers to experimental realization when its observation is impossible; 4) Theory (Θ), the field in which technology is justified, probability theory.

Objectives : We aim to address the following questions: 1) Which pros and cons are pointed out by pre-service teachers of elementary education to the use of MathCityMap (MCM)? 2) How can we characterise the participants’ engagement in a math trail performed with MCM? Design : We followed a qualitative, interpretative methodology. The paradigm choice was because the main goal was to understand the perspective and reactions of the participants to a particular situation. Setting and Participants : The participants were 48 pre-service teachers of elementary education attending the first semester of the 3rd year of an undergraduate course at a public higher education institution in Portugal. Data collection and analysis : Data were collected during the classes of a unit course on Didactics of Mathematics. The pre-service teachers answered a questionnaire, followed by the implementation of a mobile math trail. At the end of this experience, the participants filled out another questionnaire. Participant observation and audio-visual records were also applied. Thus, the analysis involved a qualitative and inductive approach, resorting to content analysis. Results : The pre-service teachers were actively engaged during the math trail, showing interest in solving the tasks, using MCM, and focused on finishing the activity, evidencing persistence and will to be involved in the discussions. We also identified anxiety and frustration related to the outcome of a particular task. Strategies of different nature were used, mainly associated to the level of cognitive demand of the tasks. As pros, they considered the app intuitive, promoting autonomy, spatial orientation and collaborative work and highlighted as cons the inaccessibility to Wi-Fi, younger students’ not having smartphones/tablets, and the limitation of answer formats in task design. Conclusions : Results encourage the use of MCM as a valuable tool in outdoor mathematics education.","PeriodicalId":36967,"journal":{"name":"Acta Scientiae","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139278421","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, astronomy research in school has not been a very active field compared to other topics. In addition, a great part of that research involves high school or university students. Few studies address the early schooling stages. Objective: Our goal is to make a narrative and bibliometric review of the articles published in relevant scientific journals from 2009 to 2019 on astronomy teaching in early childhood (0–6 years) and primary education (6–12 years), using the Big Ideas in astronomy as a conceptual framework (Lelliott Rollnick, 2010). The purposes are to characterise these studies, investigate how research on astronomy education has fostered our understanding of its learning, and analyse which methodologies and theoretical frameworks are the most frequent in them. Design: A systematic narrative and bibliometric literature review is carried out with the help of specific software (Bibliometrix and VOSwiever). Setting and participants: To locate the articles to be analysed, we used the ERIC - Education Resources Information Center resource database. We also selected research works in English centred on the educational stages of early childhood and/or primary education whose focus is one or more of the Big Ideas. They must have been published between 2009 and 2019 in journals dedicated to the didactics of experimental sciences and indexed in JCR (2019). Data collection and analysis: The data is collected systematically using a descriptive coding instrument. A bibliometric analysis is carried out, providing basic information on the analysed articles, relevant journals, trend by year of publications on the subject, publications by country and international collaboration, number of citations of the articles, and coauthorship networks, publications by year and genre, identification of the most addressed concepts through word clouds and networks of key concepts combined with cluster analysis. Likewise, we analyse issues such as the most frequent conceptual frameworks, the educational levels corresponding to the articles, and the most studied Big Ideas. Results: There is little research in international journals on astronomy teaching in the educational stages analysed, and there are practically no articles focused on early childhood education. The journal that has published the most on the subject is by far the International Journal of Science Education, and most of the studies are from the USA and published by women. The author with the most significant impact worldwide is Julia D. Plummer. The most frequent conceptual frameworks are those of conceptions and mental models. The cluster analysis of the keywords has made it possible to identify four thematic fields: mental models and conceptual change, teachers’ and students’ conceptions of astronomy, science and school, and other relevant aspects of astronomy teaching.

Inquisitiveness encourages a person's natural tendency to ask questions when faced with a confusing situation. However, students are often unable to generate effective questions to understand information from mathematics texts. Objectives : This study investigates the characteristics of inquisitive questions that arise from students in understanding mathematical texts and their impact on students' understanding of texts. Design : This study uses qualitative data and analysis of students' questions about mathematics texts. Setting and Participants : This research was conducted at Darul Ulum Islamic Boarding School University in Indonesia with 11 students. Data from three students as the most extreme cases were chosen for further discussion. Data collection and analysis : the data were obtained from observations of questions and student behavior during discussions, content analysis of written questions, and reading comprehension tests. Results : The types of questions students ask can be a predictor of their understanding level of math texts. Questions that are limited in depth, such as the questions about formulas and procedures, can indicate a lack of conceptual understanding and students' mathematical reasoning. The ability to raise inquisitive questions corresponds to an increase in understanding of mathematical texts.

Objectives : This investigation is intended to characterise the pedagogical, mathematical, and technological criteria that a prospective mathematics teacher establishes and uses when reflecting on events occurring in a virtual classroom. Design : The investigation was guided by a qualitative methodology of an exploratory-descriptive nature. Setting and Participants : the participant was a fifth-year licentiate student, and the data were collected during the second semester of 2022. Data collection and analysis : The content analysis method was used, and information was collected through questionnaires. Results : The results show that this student was able to adapt predefined schemes or proposals from the Technological, Pedagogical Content Knowledge (TPACK) model to create indicators that allowed her to carry out a descriptive but not particularly analytical reflection, however, although such adaptation was in agreement with expectations, there was little creation of new aspects.

Generally, the problems related to the theme can be solved by applying three principles: proximity, closure, and similarity. Besides, solving number pattern problems is closely related to students’ ability to present the problem mathematically . Objectives : To examine prospective teachers’ mathematical problem-solving processes based on the laws of proximity, closure, and similarity . Design : This qualitative research uses a case-study approach to achieve research objectives. Setting and participants : The researcher gave ten math questions to 67 prospective teachers (university students), choosing three to participate. The three focal participants were selected based on the categorisation results using indicators of proximity, similarity, and closure approaches from Gestalt theory. Data collection and analysis : Besides the test questions, the researcher conducted cognitive interviews with the three focal participants to confirm and explore the thought processes. Researchers used focus group discussion (FGD), cross-section data, and reviews with relevant references to validate the research outcomes. Results : The data show that the students could use the law of proximity, closure, and similarity in solving the number pattern problem, which can be seen from their ability to divide the pattern into two parts, complete it into specific geometrical shapes, and to divide it into similar shapes. In this study, prospective teachers’ thinking process schemes were also found when solving patterned number problems using the law of proximity, the law of closure, and the law of similarity. Conclusions: The students who apply proximity could divide each pattern into two parts: fixed and growth. The pattern of growth difference will become the key in generating the general form of the pattern. The students who applied closure could complete the pattern into a particular shape by adding the pattern element. Furthermore, the students who applied similarity divided the pattern into similar shapes. Every student showed a good process in making representation.","PeriodicalId":36967,"journal":{"name":"Acta Scientiae","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135168477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Being so, teachers need to understand their new role in pedagogical environments, changing their perspectives, and, most of all, transforming their knowledge to be able to teach with digital Information and Communication Technologies (ICT). Concerns about this new kind of teacher knowledge led to discussions that culminated, in the beginning of the 21st century, with the development of the Technological Pedagogical Content Knowledge (TPACK) framework. Objectives : Knowing the importance of preparing teachers to work with ICT to enrich their pedagogical practices, we propose this qualitative study that aims to analyse perceptions of a group of preservice teachers about the use of ICT in mathematics teaching and learning practices. Design : This study has a qualitative approach and it can be understood as a case study. Setting and Participants : The participants are 10 preservice teachers from a Portuguese University. Data collection and analysis : Data were collected using a survey and the responses were analysed through Discursive Textual Analysis. Results : We understand that most participants have a well-developed TPACK and they can see several educational benefits from using ICT to teach and learn mathematics.

Technology emerges with possibilities for innovative strategies aimed at enhancing learning and contributing to addressing environmental issues effectively. Teachers, in their pedagogical practices, should take into account the socio-environmental reality and integrate Environmental Education for participatory interventions in environmental issues. The use of blogs in Science education enables a more engaging interaction with the content, resulting in a more meaningful and contextualised learning experience. Objectives: To develop a blog to address household solid waste management and evaluate it as a technological tool for enhancing understanding of household solid waste management. Design: The methodology employed in this research was a qualitative approach. Setting and Participants: Thirty-five students from two seventh-grade classes at São Francisco Municipal Elementary School in the municipality of Tupandi/RS. Data collection and analysis: Two questionnaires were administered to the students, one pre-activity and another post-activity, and a blog was developed in each class. The quantitative data were analysed through descriptive statistical analysis, while the qualitative data were subjected to content analysis. Results: Most students had no prior experience with blogging, and their limited knowledge of the concept was associated with using the media tool as a page for posting personal life details. During the blog development, students did not encounter difficulties handling the platform's icons. The evaluation characterised the blog as a positive learning tool regarding household solid waste management, recognised by the students as meaningful in classroom practices. Conclusions: The development of blogs served as a technological and pedagogical strategy that facilitated learning about household solid waste management, connecting with the local reality and fostering a sense of ownership and responsibility among the students, aligning with one of the purposes of Environmental Education. Furthermore, the integration of the blog in Science education enabled the establishment of a collaborative and dynamic network for knowledge exchange, as well as the cultivation of skills related to digital literacy.","PeriodicalId":36967,"journal":{"name":"Acta Scientiae","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135548036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
