Mathematics Teaching-Research in the time of Covid19:

Difficulties and Possibilities

COVID 19 is constantly on our minds to larger or smaller degree and investigations into student performance as well as learning mathematics during the pandemic are important to determine the best course of action. It is becoming clear that changes in pedagogy required from us by the pandemic will be substantial if we want to engage all possible available routes of e-learning. A bisociative frame is created between the past pedagogy and new circumstances, the structural frame, which is a prerequisite to creativity of Aha! Moment. Thus it is our own classroom creativity that is called here for engagement.

We start the issue with the work of Ariyanti and Santoso from Indonesia who inform about a simple yet statistically rigorous comparison of student work before and after Pandemic. Their results definitely demonstrate lowering of student achievement during the Covid19 distance learning.

We follow that analysis with the work of Baker and his colleagues in the Bronx who investigate the impact of COVID 19 restrictions upon the facilitation of creativity of Aha!Moment. Baker et al are using this occasion to lay the short background of the methodology of facilitation and assessment of the depth of creativity. They show that the characterization of Aha!Moment by three criteria of: search, connection and resulting novel process do a good job in the analysis of the depth of creativity within Aha!Moment.

They report that the main impact of the distance learning on the facilitation process is in the constraints upon interaction between students as well as upon student/teacher interaction created by the online approach. Since such an interaction is essential for the creativity facilitation process, one can expect lowering of the level of creativity in the mathematics classrooms.

The third article in the Covid series by Fuchs and Tsaganea provides multidimensional analysis of the COVID impact upon teaching in NYC as well as in the whole country. They discover quite a few advantages of online teaching in relation to the limitations of face-to-face teaching, which nonetheless has been seen as the best pedagogical method. However, they point out that the societal changes due to COVID will stay with us much longer and they urge educators and students to develop mastery of online teaching and learning.

We supplement these three COVID related papers by the interesting paper of Stokes and Sanfratello, which although written before the pandemic struck, nonetheless offers an interesting pedagogy of “learning through doing”, that eliminates math anxiety. As the long term effects of the pandemic upon learning are still unknown the experiential approach based on patterns and deliberate practice while grounded in the problem solving model of creativity/innovation offers the pathway of success for those students who have experienced higher levels of math anxiety in new online learning circumstances.

We complete this issue with two papers analyzing classroom effectiveness of two geometrical software, Geogebra and Geometer Sketchpad. At present, geometrical oriented mathematical software might be very useful in contemporary online mathematical classrooms. It can provide mediating visual pathway between the student and the teacher while increasing and deepening their interaction.

Raj Joshi and Singh from Nepal demonstrate high effectiveness of Geogebra for learning linear equation through the simple experimental group/control group investigation. They point out to the versality of Geogebra to teaching variety of mathematical domains from arithmetic to calculus; it could be especially useful for distance learning.

The paper of Hartono from Indonesia investigates effectiveness of Geometer Sketchpad (GSP) in guiding student understanding of two dimensional objects. The author describes three months long teaching experiment comparing student (7th grade) achievement between two cohorts, experimental with GSP software, and control with traditional learning. The positive result of the teaching experiment needs to be repeated during pandemic, however it’s clear that both geometrical software can positively impact mathematics learning and teaching during that critical time.

**Editorial from Paul Ernest**

The philosophy of mathematics education can be traced back to the work of Plato. In his Republic Plato considered deeply the role and purpose of mathematics in teaching and learning. His enquiries were founded on ethics, for questions of meaning and purpose within a social context inevitably bring in the Good. At the same time, he was interested in the epistemology and ontology of mathematics and its relations with the Truth and Beauty. Overall, Plato displayed great interest in the subject of mathematics throughout his philosophical work, and he is an inspirational godfather and patron saint of the philosophy of mathematics education.

Current mathematics education research is mostly concerned with two questions, one epistemological and the second methodological. The epistemological questions asks what is mathematical truth and how do we justify and explain it, and above all, how to we come to know it? The methodological questions concern how we can best and most effectively teach and facilitate the learning of mathematics. Research in the philosophy of mathematics education also addresses epistemological questions of mathematics and its teaching and learning, but it does so more explicitly, more theoretically. In addition, it considers the ontological, aesthetic and ethical issues of mathematics with respect to education and society.

The philosophy of mathematics education is an interdisciplinary area of research that incorporates many questions.

- What are the goals and purposes of mathematics education?
- What can we learn from deep analyses of the methods and means of teaching and learning mathematics, as well as from studying the underlying theories and philosophies?
- What new insights are revealed by the application of deep theoretical approaches including Phenomenology, Hermeneutics, Complexity, Embodiment and Critical Theory within research in the philosophy of mathematics education?
- What are the relationships between and, the mutual influences on each other, of the philosophy of mathematics and mathematics education?
- How do the personal philosophies of mathematics and mathematics education of learners, teachers, teacher educators and researchers impact on practice?
- How are the different actors of interest including students, teachers, researchers, theorists, philosophers and mathematicians linked together professionally within the fields of mathematics education research and practice?
- How do mathematics and the philosophy of mathematics impact on the nature, structure and content of mathematics for teaching?
- What do deep analyses of mathematics itself tell us about its structures, processes and fundamental concepts and about their relationships with its teaching and learning?

This special issue offers a range of partial answers to these question, and suggested pathways to further extend research in the areas. It represents work in progress from worldwide scholars including both northern and southern hemispheres, and from the east and the west. Every continent barring Australia is represented, thus providing a truly global representation of work in progress.

This volume is divided into four parts, a tetrahedron whose faces represent different directions of inquiry in the philosophy of mathematics education.

First, there are papers about the philosophical foundations of mathematics education research including foundational issues of research and methodologies and paradigms, meaning and the semiotics of mathematics and mathematics and the special mathematical issues of rigor and axiomatics.

Second, there are the philosophical dimensions of teaching, learning and teacher education including: teachers’ epistemologies and the use of incompleteness theorems in teacher education, critical examinations of constructivist theory, mediation in Vygotskian theory, the use of French Didactique and French notions of knowing in China, as well the crowning purposes of learning mathematics.

Third, there are future oriented visions of how the theory and practice of teaching and learning mathematics might be developed. This includes questions such as how can we theorize sustainable development in mathematics education? How can we incorporate philosophy of mathematics education and theories of imagination for normal students? How can or should we introduce the theory of infinity and George Spencer-Brown’s laws of form in the teaching and learning of mathematics?

Fourth, philosophy and the humanities are home to many grand and widely used theories beyond our own multidisciplinary field. How can we bring them into mathematics education to extend its philosophical foundations and the underlying research paradigms? In what ways can we utilize Phenomenology, Hermeneutics, Complexity Theory, Embodiment, Critical Theory and Critical Pedagogy in our research and teaching practices? The papers in this section offer tentative accounts of the achievements so far, in pursuing these directions of research.

All these papers were due to be presented in Shanghai July 2020 at the International Congress of Mathematical Education. This, of course, needed to be postponed because of the Covid-19 pandemic. Instead, the papers have been rewritten, extended and improved for publication here, without waiting until after the conference. So, something positive has come out of this crisis. We present to you, the philosophy of mathematics education 2020, the current state of the art, for your edification and enjoyment!
