In this perspective, research works that address the meanings attributed by students and the degree of difficulty in learning themes commonly taught in this subject are of great importance. Objective: To understand the meanings attributed by the students of an integrated course of a federal institute on chemistry and evaluate the degree of difficulty they attributed to the subjects taught. Design: Research with mixed methods and convergent design. Setting and participants: 90 students from the first, second, and third years of an integrated chemistry course at a federal institute participated in the research. Data collection and analysis: Questionnaires were applied to know why students think it is good or bad to study chemistry. The students also mentioned difficulty learning some of the subjects taught. Results: According to the students, it is good to study chemistry because it addresses everyday issues and helps us to get to know the world. The negative points are the difficulty and complexity of theoretical themes and the involvement of calculations. Conclusions: Themes that are difficult to visualise or those in which the chemical language is not contextualised are the most difficult to learn.","PeriodicalId":36967,"journal":{"name":"Acta Scientiae","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47345104","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}

Initially, the semiotic perspective in the teaching process will be addressed and, subsequently, the role of gestures and non-verbal communication as a semiotic resource. Objective: To investigate the contribution of gestures as a potential semiotic resource in teaching Bohr’s atom model. Design: The principles of a qualitative study were observed. Setting and participants: Videos of a preparatory course for ENEM, in the subject of Physics, made by the secretary of education of the state of RS, Brazil, free of charge via the internet. Data collection and analysis: A total of seven hours of online classes of a preparatory course for ENEM are analysed. For the gestural microanalysis, episodes on Bohr’s atom were chosen, with two distinct episodes: the first on the photon and the second on energy levels. Results: From the research analysis carried out on signs within the Peircean framework, it is possible to infer that gestures have the potential to be used as a semiotic resource in the classroom. Conclusion: We found that gestures can be a potential semiotic resource in teaching Bohr’s atom model, as they can enable an articulation between different semiotic resources.","PeriodicalId":36967,"journal":{"name":"Acta Scientiae","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47414179","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}

Objectives: To investigate the contributions of a tactile adapted version of the historical narrative “Eratosthenes and the Circumference of the Earth” in the formation of geometry concepts in visually impaired students and the challenges associated with the teaching process, this proposal is based on the application of an adapted didactic structure through Eratosthenes’ historical narrative, focusing on teaching the similarity of triangles and geometry. The study was based on Vygotsky’s cultural-historical theory and Galperin’s theory of the gradual formation of mental actions. Design: The methods are qualitative in nature via a case-study strategy. Environment and participants: The research was conducted with a class of 46 students, of which one is visually impaired, attending the first grade of high school at a public institution in the countryside of Paraná-Brazil. Data collection and analysis: Data were collected through activities performed in class and an evaluation questionnaire. Data were analysed through content analysis. Results: The results show that the intervention contributed to the assimilation of mathematical concepts by the visually impaired individual and other students, showing changes in the perceptions of key topics within plane geometry, previously demonstrated by the students as partial and non-scientific concepts. Conclusions: We can emphasise the need for research and studies targeting the construction of proposals and materials that enable an equitable and inclusive teaching process for all students.","PeriodicalId":36967,"journal":{"name":"Acta Scientiae","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41780588","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}

There is an agreement regarding problem-solving as a fundamental part of mathematical competence, and some authors regard reversible thinking as a requirement for it. Objectives : We want to validate an instrument that assesses the reversibility of thought when solving verbal arithmetic problems (word problems) involving various operations, semantic-mathematical structures and proximity of situational information. Design : A qualitative study was carried out from the data obtained by experts, and a quantitative study was carried out to determine the validity and reliability of the instrument. Setting and Participants : 318 students from different Spanish schools attending primary education (6 to 12 years) participated. Data collection and analysis: Participants performed 180 mathematical tasks distributed over three theoretical scales, two operations, and four semantic configurations. Results: To determine the consistency of the data, a reliability analysis was performed globally and on each of the scales, all values being greater than 0.90. Exploratory factor analysis resulted in three factors that explained more than 70%. To analyse the validity of the instrument, confirmatory factor analysis was performed, and its indices showed an adjustment of the models. Conclusions : We consider that the designed instrument is sufficiently robust to assess the reversibility of the basic addition and subtraction operations and, in addition, to analyse the discrimination of word problems according to the semantic-mathematical structure and their situational context.","PeriodicalId":36967,"journal":{"name":"Acta Scientiae","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44949611","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}

For this reason, studies that contribute to conceptualising mathematical objects associated with the differential equation are important, particularly the existence and uniqueness theorem. Objectives : From its genesis, the objective is to analyse the nature of this knowledge, its epistemology from practice. We give an account of the variational arguments , i.e. , based on practices focused on the study of change, with a predictive purpose, which allows obtaining the desired result on the differential equation: demonstrating the existence of a unique solution. Design : A documentary analysis is carried out from the Socioepistemological Theory of the works that marked the construction of this mathematical knowledge. Setting and Participants : Being a documentary-cut study, we did not have participants stricto sensu . Data collection and analysis : Our observation unit includes mathematical works as primary and secondary sources involved in constructing the theorem: its postulations, search for hypotheses and proofs. Results : A reconstruction of the theorem is offered, which from the arguments, characterises some practices that helped in the construction of mathematical objects. Conclusions : We conclude that the bounded variation, as a particular way of using change, contributed to the search or establishment of conditions for the interpretation of the solution of equations and to obtain a unique solution to the differential equation, contributions that should be key for implementations of learning situations.","PeriodicalId":36967,"journal":{"name":"Acta Scientiae","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42835452","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}

Objectives : This paper describes and analyses a training intervention with prospective teachers to develop such competence using proportionality tasks. Design: This qualitative and interpretative study adopts a methodology characteristic of didactic design or engineering research. The design of the intervention and the content analysis of the participants’ answers use theoretical and methodological tools from the onto-semiotic approach to mathematical knowledge and instruction. Context and participants : The training action was carried out with 127 undergraduates attending a primary education teaching degree in the framework of the Design and Development of the Mathematics Curriculum in Primary Education subject in a Spanish university. Data collection and analysis: The prospective teachers, organised in 33 working teams, were asked to create two problems based on a given situation and to identify objects and difficulties, the solution of which was analysed by the research team. Results: The results show that the participants encounter difficulties in elaborating relevant proportionality problems from the given situation, identifying the associated level of complexity, recognising the mathematical objects interacting in the solution to their problems and the difficulties that these could cause to primary school pupils.

Design: Mixed, the frequency and feasibility are consulted through a questionnaire and in-depth interviews. Participants : Thirty in-service mathematics teachers answered the survey and of ten invited, three agreed to be interviewed. Data analysis : We carried out a descriptive analysis for quantitative data and qualitative thematic analysis. Results : The strategies of collecting evidence, feedback, collaboration, and self-regulated involvement in learning are viable and frequent in mathematics education, however, the strategy of clarifying and sharing goals requires adaptation to the context. In addition, nine novel FA practices are described. The implementation of formative assessment creates tensions with the summative function, it is laborious to implement and consequently takes time outside the classroom.

Education 4.0 emerged as a response to the need to meet the demands that will undoubtedly arise with the way society has been developing in the direction of the so-called Innovation Society. Objectives: The objective of this work was to elaborate a model of the Education 4.0 teacher, integrating Siemens’ Connectivist Theory with Papert’s Constructionism. Design: The methodology used here consisted of the textual analysis of the primary sources of Siemens’ Connectivist proposal and Papert’s Constructionism, aiming to identify characteristics that can lead the teacher of Education 4.0. Environment and participants: The primary sources of Siemens’ Connectivist proposal and Papert’s Constructionism, as it is a bibliographic theoretical study. Data collection and analysis: Data were collected from the mentioned primary sources and analysed by textual analysis. Results: As a result, seven possible characteristics of the Education 4.0 teacher were identified: Mediator, Researcher, Adaptive, Mentor, Apprentice, Bricoleur, and Self-reflective. However, the survey carried out by digital means with 30 active and non-active teachers revealed that 53.3% were unaware of the concept of Education 4.0.
