The roles of gestural and symbolic schematizations in inhibition as a component of executive functions
(Springer, 2023) Khatin-Zadeh, Omid; Farina, Mirko; Yazdani-Fazlabadi, Babak; Hu, Jiehui; Trumpower, David; Marmolejo-Ramos, Fernando; Farsani, Danyal
The role of gestural schematization in enhancing thinking processes has been the subject of a large body of works. In this process, contextually unimportant or irrelevant information related to a concept (or a system of concepts) is deleted or ignored, while relevant spatial information is maintained. This process is a special type of inhibition, which is one of the key components of executive functions. In this short paper, it is suggested that gestural schematization is a special type of symbolic schematization, a much more general process through which irrelevant information related to features of a concept (or a system of concepts) is suppressed, while relevant information (spatial and non-spatial) is maintained. Through symbolic schematization, abstract structural similarity between two concepts or between two systems of concepts can be discovered. In this way, an individual’s knowledge about the first situation can be generalized to the second situation. Symbolic schematization is the basis of abstraction, knowledge generalization, and knowledge development. This is particularly the case with abstract mathematical thinking. This proposal offers a picture of cognitive mechanisms through which knowledge of abstract mathematical concepts is created and developed in the mind.
More than words: an integrated framework for exploring gestures’ role in bilinguals’ use of two languages for making mathematical meaning
(Springer, 2022) Krause, Christina; Farsani, Danyal
Gestures play a role in perception, production, and comprehension of language and have been shown to difer cross-linguistically and cross-culturally in aspects of performance and form-meaning relationships. Furthermore, gestures can serve as analytical tools to access tacit embodied-imagistic mathematical meanings that add to verbal-linguistic dimensions of meaning. At the same time, language plays important roles in interaction and cognition, infuencing bilinguals’ learning of mathematics. Still, there is only very little research attending to the use of gestures of multilinguals as means to better understand the relationships between their language use and their mathematical thinking. This paper builds on research on multilingualism and on gestures—related and unrelated to mathematics education—to motivate and develop a framework for understanding better mathematics thinking and learning of multilinguals through integrating gesture analysis as related to languages, culture, and the use of registers. The application of this framework will be illustrated through two case studies in which we analyse interview data of a bilingual student and a bilingual mathematics teacher—focusing on gestures and language use while talking about the mathematical concept of ‘power’—or exponents—in Farsi (Persian) and in English. From analyzing the gestures’ form-meaning relations and their functions as related to hybrid language practices, we hypothesize on the vernacular and mathematical context as activated in both speech and gesture and on how it relates to mathematical meaning. From this, we draw practical implications for multilingual mathematical learning contexts and discuss implications for research on multilinguals’ mathematical thinking and learning.
The impact of gestural representation of metaphor schema on metaphor comprehension
(De Gruyter Mouton, 2023) Khatin-Zadeh, Omid; Hu, Jiehui; Marmolejo-Ramos, Fernando; Farsani, Danyal
This study aimed to investigate how priming a metaphor by the gestural representation of its schema affects the understanding of that metaphor. In each of the two tests, different groups of participants were invited to judge the sensibility of the same 20 metaphors preceded by congruent versus incongruent gesture primes as compared to no prime. In the congruent gesture-prime conditions, each metaphor was preceded by a gesture that represented the schema of the subsequent metaphor whereas this gesture was not compatible with the schema of the subsequent metaphor in the incongruent gesture-prime conditions. Results showed that a higher proportion of sentences were judged to be sensible in the congruent gesture-prime conditions compared to no-prime and incongruent gesture-prime conditions. Also, response times of sensibility judgements were shorter in congruent gesture-prime conditions compared to no-prime and incongruent gesture-prime conditions. These results suggest that metaphor schema affects metaphor comprehension through the activation of metaphorically-relevant information and suppressing irrelevant information.
Formación inicial docente basada en el practicum: la academia reflexiva como praxis fundamental para la formación de profesores
(Universidad Pedagógica Nacional de Colombia, 2023-01-01) Becerra-Sepúlveda, Carolina; Ibáñez-Muñoz, Rosa; Valenzuela-Giovanetti, Ezia
La calidad de la Educación constituye un compromiso y un deber con el sistema escolar; esta demanda atención especial a la Formación Inicial Docente de nuestros Profesores. Actualmente las Políticas Públicas en Chile desafían a las Universidades en cuanto a diversos requerimientos para la Formación de Profesores. Conscientes de esta situación, las universidades han instalado estrategias para mejorar los procesos formativos de sus futuros profesores, estableciendo mecanismos formales que articulan su currículo con una formación basada en la Práctica. Este artículo expone los resultados de una investigación cualitativa, que analiza el proceso de práctica de las carreras de pedagogía de una universidad privada en Chile, describiendo a su vez, los nudos críticos de los procesos formativos que la caracterizan. El estudio contempló un diseño etnometodológico, contando con la participación de 37 docentes tutores de prácticas y tres coordinadores, a través de un focus group. El abordaje de la información recopilada contempló un análisis del discurso a través de la herramienta Atlasti. Los resultados del estudio relevan la necesidad de repensar la práctica en la formación inicial docente a través de un modelo que represente y responda a las demandas de la sociedad del siglo XXI, en conjunto con la valorización del acto reflexivo al interior de la Academia que nutre y fortalece la formación inicial docente.
Design-based development of educative curriculum material for deliberative human rights education
(Taylor & Francis, 2023-06) Guzmán, Valentina; Larrain, Antonia; Álvarez Valdés, Carolina; Fernández, Ivettre; Herrera, David; Urrutia, Camila
Human rights education (HRE) is an urgent historically and globally recognized challenge for societies. However, it has not been sufficiently addressed by empirical and theoretical research in education. Based on the UN Declaration on Human Rights Education and Training (UNDHRET), there is wide agreement that HRE should include education about, through, and for human rights. We argue that a situated deliberative pedagogy can offer these three dimensions to HRE. However, this is not without challenges for teachers and students. One way to deal with these challenges and support this pedagogical innovation is to design curriculum material that supports teachers. To contribute to this, we conducted a design-based research (DBR) aimed at participative designing of educative curriculum material for human rights deliberative education. Four teachers participated in two phases of the study. Two participated in refining the material’s structure and its controversies and the other two participated in discussing the dilemmas and activities relating to implementation of the material at school with their 11th- and 12th-grade students. The results show participatory educative curriculum material designed for holistic HRE: about, through, and for HR. The implications and problems of the design process associated with a deliberative curriculum for HRE are discussed.
Entre el reconocimiento y las trayectorias biográficas: una mirada sobre las juventudes en Argentina y Latinoamérica
(Universidad de Chile; Facultad de Ciencias Sociales, 2022-10) Carreras, Rafael Antonio; Escobar González, Sebastián
En el contexto de entrevistas realizadas a distintos investigadores de relevancia en el campo de estudio de las juventudes en América Latina y Europa, conversamos con Rafael Carreras, académico e investigador de la Universidad Nacional de Córdoba, construyendo un relato sobre su trayectoria académica considerando distintas variables que han marcado su labor, la psicología social comunitaria, el trabajo territorial con jóvenes y el uso de relatos biográficos en clave investigación-acción participante en el contexto argentino. La conversación comienza justamente con el origen del interés investigativo por las juventudes, donde el contexto sociopolítico es fundamental para iniciarse en la exploración de dicho grupo social. Así, se transita en distintas reflexiones sobre las juventudes en el contexto argentino y latinoamericano, integrando conceptos como neoliberalismo o pluridomonio. Finalmente, se establecen ciertas aperturas y pistas para estudiar a las juventudes en el actual contexto latinoamericano, el cual ha estado impactado por diversos hitos de protesta, violencia y transformación social.
Estudiantes con gratuidad en universidades prestigiosas: ajustes académicos para permanecer
(Centro de Estudios Avanzados en Niñez y Juventud del Cinde; Universidad de Manizales., 2023-08-25) Álvarez Valdés, Carolina
La educación superior en Chile se ha masificado; sin embargo, se mantiene una alta segmentación en el sistema. En 2016 comienza a implementarse la política de gratuidad, dirigida a estudiantes de menores ingresos. Esta investigación buscó comprender las experiencias académicas de estudiantes con gratuidad en universidades prestigiosas y selectivas, espacios tradicionalmente de reproducción de las clases altas y élites. Se realizaron entrevistas biográficas a trece estudiantes de estas universidades, así como un análisis temático temporal. Los resultados muestran que la obtención de la gratuidad emerge como un facilitador en el acceso, pero los/as estudiantes experimentan fuertes sensaciones de inadecuación académica; se muestran activos en transformar sus disposiciones, realizando un fuerte trabajo sobre sí para permanecer. Las experiencias de jóvenes de menores capitales muestran la persistencia de desigualdades.
La pareja pedagógica como experiencia desde la práctica para el desarrollo de desempeños colaborativos orientados a la coenseñanza
(Universidad Bernardo O'Higgins, 2023-07-31) Pérez Carrillo, David Jacob; Alvarez Aranda, Nelly del Pilar; Jiménez Vivas, Amparo
El trabajo colaborativo es uno de los desafíos que se instala al interior de la Formación Inicial Docente a partir de las actualizaciones que ha sufrido la política pública en Chile. Para dicho propósito, el presente artículo sistematiza los resultados de un proyecto de investigación que recurrió al dispositivo pareja pedagógica a fin de promover el desarrollo de desempeños colaborativos que tributen en los procesos de identidad docente, en estudiantes que cursaron práctica profesional en las carreras de Pedagogía en Educación Diferencial e Historia y Geografía. Para ello, se analizaron sus respuestas a partir de dos instrumentos aplicados al inicio y al final de su práctica en dupla, concluyéndose que la pareja pedagógica favorece el desarrollo de procesos identitarios de carácter colaborativo, expresados en un reconocimiento del otro como un modelo a seguir; como una experiencia que amplía el conocimiento didáctico y pedagógico, y como una experiencia que permite generar mayores seguridades en el ejercicio de la profesión. Por otra parte, los resultados reclaman mayores instancias para la reflexibilidad que se orienten a desmantelar posiciones de poder de los profesores de enseñanza regular sobre los profesores especialistas, posturas que se constituyen en obstaculizadores para la profundización de prácticas pedagógicas colaborativas e inclusivas.
Future early childhood teachers designing problem-solving activities
(Bandung Himpunan Matematika Indonesia (IndoMS) bekerjasama dengan Program S2 Pendidikan Matematika, FKIP, Universitas Sriwijaya Palembang, 2022-06) Sala-Sebastià, Gemma; Breda, Adriana; Farsani, Danyal
This work aims to identify the criteria to design activities based on problem solving tasks that emerge when future early childhood education teachers jointly plan their activities and reflect on them. The participants were 76 students from the Didactics of mathematics subject that was carried out in the 2nd year of the Early Childhood Education Degree of a Catalan public university. This is qualitative research in which the phases of the thematic analysis have been adapted: familiarizing with the data; systematically applying the categories to identify the student criteria emerged; triangulating the analysis with experts; reviewing and discussing the results. The Didactic Suitability Criteria (DSC), from the Ontosemiotic approach (OSA) framework to design tasks and their indicators, were used to categorise and analyse the tasks performed by future teachers. As a result, it was identified that when the future teachers adopt consensually design their activities, they are implicitly based on the Didactic Suitability Criteria (DSC). Still, not all their indicators emerge since their reflection is spontaneous and is not guided by an explicit guideline that serves them to show their didactic analysis in detail. The study concludes that it would be convenient to offer future teachers a tool, such as DSC, to have explicit criteria to guide the designs of their mathematical tasks. In this sense, a future line of research opens, much needed, to adapt the DSC to the singularities of this educational stage.
A study of using metaphoric and beat gestures with motion-based and non-motion-based metaphors during retelling stories
(MDPI, 2022-04) Khatin-Zadeh, Omid; Farsani, Danyal; Reali, Florencia
In this paper, we classify metaphors into four categories: motion-based metaphors, static space-based metaphors, static object-based metaphors, and static event-based metaphors. Then, a study that investigated the use of gestures with these types of metaphors is reported. The aim was to examine how these types of metaphors are used with metaphoric and beat gestures during the process of re-telling stories. The participants of the study listened to three audio stories. Each story contained two motion-based metaphors, two static space-based metaphors, two static object-based metaphors, and two static event-based metaphors. After listening to each story, they had to retell the stories in front of a camera. The videos were analyzed to determine the number of metaphoric gestures and beat gestures that had been used by participants during the retelling of the stories. The results showed that the highest number of metaphoric gestures had been used with static space based metaphors. This was followed by motion-based metaphors, static object-based metaphors, and static event-based metaphors, respectively. On the other hand, the highest number of beat gestures was used with static event-based metaphors. These findings indicate that the use of metaphoric gestures and beat gestures accompanying metaphors is highly dependent on the spatial and motoric properties of the base of the metaphors, which supports the idea of embodied metaphor comprehension.
Análisis de la atención visual de estudiantes a través de gafas espía
(Universidad Nacional de Costa Rica, 2022-06) Farsani, Danyal; Villa-Ochoa, Jhony Alexander
La atención visual es un indicador importante en las interacciones entre docentes y estudiantes. Este artículo presenta los resultados de un estudio que buscó determinar cómo fluctúa la atención visual que los estudiantes prestan a la persona docente durante sus clases de matemáticas e inglés y detectar posibles diferencias en dicha atención. El estudio se llevó a cabo en una escuela secundaria con una muestra de 16 estudiantes (varones). Los datos se obtuvieron a través de una mini cámara de video, montada sobre las gafas que son usadas por los estudiantes. A través del uso de imágenes de Google, analizamos de manera automática y objetiva 2613 fotogramas de las grabaciones en las que la persona docente de la clase aparecía en el campo visual de los estudiantes. Los resultados dan cuenta de la diferencia en la atención visual de los estudiantes entre los introvertidos y los extrovertidos durante los 90 minutos de clase. También se observó que los estudiantes estaban más comprometidos visualmente cuando el discurso de la persona docente estaba acompañado de gestos. Se destaca la importancia de diversificar las interacciones que busque otras formas de comprometer a los estudiantes en los últimos dos tercios de la clase. Algunas implicaciones para los programas de desarrollo profesional se derivan de este estudio.
Non-verbal interaction and students’ visual engagement in mathematics and English classes
(Universidade Luterana do Brasil, 2022-07) Farsani, Danyal; Breda, Adriana; Sala-Sebastià, Gemma
Background: The interactions in the classroom are of particular interest to the teaching and learning processes. Objectives: This study examines nonverbal interaction in mathematics classrooms, and how different modes of nonverbalbehaviour, contributed to the engagement in lessons. Design: A quantitative study. Setting and Participants: 30 randomly selected students wore mini camera-mounted eyeglasses in their mathematics and English lessons. Approximately 45 hours of video recording were made from these cameras (from a first-person’s perspective) to analyse and compare the nonverbal interaction in mathematics and English lessons. Data collection and analysis: In Google Images, we objectively searched and statistically analysed frames in which the class teachers appeared within the students’ visual field. Results: The results show that how students are visually engaged with the teacher depends on a set of proxemics. Differences were found related to visual attention both regarding the subject matter and the different proxemics of the student in relation to the teacher, pointing out that students are more visually involved with the teachers’ instructions when at a proxemic of 1.20 to 3.70 meters. Furthermore, we report differences between boys and girls and how they are visually engaged in their mathematics classrooms. Conclusions: Finally, we report how teachers pointing gestures can serve as a tool to recapture students’ visual attention in mathematics classrooms.
Reflections of future kindergarten teachers on the design of didactic sequences with the use of robots
(Modestus, 2022-08) Seckel, María José; Breda, Adriana; Farsani, Danyal; Parra, José
The purpose of this study is to analyze the reflections of future kindergarten teachers when designing didactic sequences with the use of the bee-bot robot. A qualitative methodological design was followed to achieve this objective, collecting the data through a written record prepared by the participants from collaborative work. A total of 25 future teachers participated, forming six working groups. The data were analyzed with the content analysis technique, considering the criteria of didactic suitability–epistemic, cognitive, interactional, mediational, affective, and ecological–and their respective components. The results suggest that at the moment prior to the design of the didactic sequences, the reflections of the groups of future teachers are related only to some criteria, while, in the design of the proposed teaching and learning process, the units of analysis were related to all six criteria. With the results obtained, it is concluded that a future implementation and observation of the design of didactic sequences by the participants would allow the participants to consider more components of the criteria when reflecting. In addition, it is concluded that training that contemplates the criteria of didactic suitability, would also allow future teachers to deepen their reflections, guiding them with these tools.
Developing conceptual understanding of Irrational numbers based on technology through activity system
(City University of New York, 2022) Rafiepour, Abolfazl; Abdolahpour, Kazem; Farsani, Danyal
The main purpose of this study is to develop a conceptual understanding of the irrational number of the square root of 2 ( 2 ). Participants in the study were 20 ninth-grade male students. Activity Theory was used as a framework to show the development of the conceptual understanding. Since this study was conducted during the COVID-19 pandemic; online teaching method was adopted. In this teaching method, WhatsApp messaging and calculator were used as our basic technology. Virtual education lasted 2 sessions (120 minutes) for the development conceptual understanding of the irrational number of square root of 2. To produce data, WhatsApp Export Capability was used. For data analysis, the online teaching activity system was used. By analyzing this activity system, three tensions were understood. Modifying these tensions, has led to their students making the concept of the irrational number of the square root of 2 ( 2 ) and reach a single definition
How are fortuity mathematical movements o mosquitoes represented in children’s drawings?
(City University of New York, 2022) Reyes-Santander, Pamela; Luci, Gina; Farsani, Danyal
This exploratory and experimental research aims to describe randomness expressed in 5 to 6-year-old children’s drawings. This study considers a six-day activity developed in 5 Chilean kindergartens, with a total of 142 participants. The activity on the mosquito’s flight considered the corporal movements to generate the idea of randomness in children. The children drew the mosquito flight and described the flight. We qualitatively analyzed and categorized the children’s drawings and verbal descriptions, dividing them into static or dynamic representations. A second grouping was established in the dynamic drawings: in one direction and random. The third division considers only random drawings: (1) uncertain walk, (2) possible walk, and (3) casual walk. The results show that children in this stage of development can express in their drawings some of the three basic notions of randomness. The children expressed randomness through random stops, circular paths, and arrows to mark positions or make decision possibilities of the mosquito
Preservice science teacher education around the globe. Trends, challenges, and future directions
(Routledge, 2022-04-27) Cofré, Hernán; Vergara, Claudia; Santibáñez, David; Pavez, José Manuel
This chapter describes and analyzes four of the most relevant aspects of preservice science teacher education (PSTE) around the world: routes and training systems; curricula; characteristics of practicums; and the relevance of research. According to analysis of more than 25 countries, we conclude that in Europe, programs move towards higher qualifications for teachers at a master’s degree level; while in Asian and American countries, shorter, more pragmatic, and pedagogy-based programs are the most common. In most countries, there still exists room for an increase in learning experiences focused on the development of pedagogical content knowledge, such as science methods courses and practicums.
Developing an Instrument to Assess Pedagogical Content Knowledge for Evolution
(Springer Nature, 2022-02-18) Becerra, Beatriz; Núñez, Paola; Vergara, Claudia; Santibáñez, David; Krüger, Dirk; Cofré, Hernán
Despite the importance of evolution to understand biology, there is signifcant evidence that many biology teachers have difculties to successfully teach this topic. The purpose of this study is to describe procedures by which a paper-and-pencil instrument to assess teachers’ pedagogical content knowledge for evolution (PCKevo) was developed and validated. The instrument was created to measure the components proposed in the model of Magnusson et al. (1999), except for the orientations. The creation of the questionnaire was carried out through eleven steps: (1) conceptualization, (2–4) creation of items and rubric reviewed by experts (focus on content and construct validity), (5–7) piloting a 32-item questionnaire to 10 biology teachers (focus on face and construct validity and reliability), (8–10) piloting a 16-item questionnaire to 61 biology teachers (focus on discriminant and construct validity and reliability), (11) application of a diferent instrument (CoRe interview) to four teachers (focus on criterion validity). The fnal version of the questionnaire (which includes three PCK components) showed in a Rasch analysis for the reliability of the items (α=0.90) and persons (α=0.81) adequate values. When applying the fnal version of the questionnaire, there is also evidence of discriminant validity (diferences between two groups of teachers with or without professional development in evolution education). The contributions of the PCKevo instrument for research topics and evolution teaching are discussed.
How do university students of different ethnic backgrounds perceive factors that hinder learning in STEM and non-STEM majors?
(Taylor and Francis, 2021-04-01) Radmehr, Farzad; Niazi, Najmeh; Rezvanifard, Faezeh; Farsani, Danyal; Laban, Winnie; Overton, John; Bakker, Leon
This study explores university students’ perceptions of factors that hinder student learning with particular attention to students’ discipline (STEM vs non-STEM) and ethnicity. A sample of 1684 university students in New Zealand participated in this study. Students’ responses to an open-ended question were first inductively coded and then quantitatively analyzed using Chi-square independence test and logistic regression. The findings identified several situational, dispositional, and institutional factors that hinder student learning, among them financial difficulties and work commitments, health, and family issues were more dominant. These factors are perceived differently by students of different disciplines and ethnicities. For instance, Asian students were less likely to refer to financial difficulties and work commitments compared to the other ethnicities, whereas Pasifika and then Māori students perceived family issues more than other ethnic groups. STEM major students were more likely to believe the teaching quality restricts their learning than their non-STEM counterparts. The study findings have several educational and well-being implications for diverse bodies of students in tertiary education.
Autorreflexión en la trayectoria docente: propuesta para su desarrollo desde el modelo SIC
(Universidad Técnica de Manabí, 2021-10-22) Luci-Arriagada, Gina; Haas Prieto, Valentina; Cárdenas Berrio, María Karla
El artículo aborda los principios fundamentales sobre los que se basa el modelo de autorreflexión SIC (Sentido – Intervención – Cierre). Dicho modelo se sustenta en los aportes teóricos de Zimmerman, fundamentalmente. Este modelo ofrece preguntas orientadoras a partir de tres fases de trabajo para el proceso de autorreflexión en la práctica docente como profesión. A partir de este modelo de carácter cualitativo, se plantea la necesidad de contar con una herramienta más operativa que permita medir desde el punto de vista de los docentes, la autorreflexión teniendo en cuenta varias dimensiones que involucran el saber práctico y la construcción del saber pedagógico en el proceso docente. Dicho instrumento ha sido confeccionado a partir de la experiencia de las autoras y la revisión bibliográfica, el que se ha validado en diversas instancias formativas.
Modelling and applications in Iran school mathematics curriculum: voices of math teachers
(City University of New York, 2021) Rafiepour, Abolfazl; Farsani, Danyal
In this paper, six mathematics curriculum changes in Iran are reviewed, spanning from 1900 to 2021. Change of forces, barriers, and the main features of each reform are represented. Specifically, the first five curriculum changes are described briefly and the sixth and most recent one is elaborated upon, with more detail as contemporary school mathematics curriculum change. This recent curriculum reform will be then analyzed using an application and modeling approach, followed by reflections from five teachers of mathematics’ voices about how they implemented recent curriculum reform after passing modelling course in their master’s program. These teachers shared their professional beliefs about the role of the modelling course in shaping their classroom practices. We believe that the practical aspects of this paper can have enormous implications for other mathematics teachers in developing countries.
