Preservice Mathematics Teachers’ In-the-Moment Noticing Skills
As student-centered teaching approaches has become popular in recent years, teachers’ noticing skills in terms of paying attention to students’ mathematical thinking and responding them accordingly has become one of the prominent issues investigated by scholars. The studies revealed that development of teachers’ noticing skills should be supported for effective teaching. In this study, the nature and development of preservice mathematics teachers’ in-the-moment noticing skills was investigated. Throughout 2016-2017 academic year, a total of 10 preservice mathematics teachers worked with 7th grade students on the mathematical tasks mostly developed by the research team. In this article, only the findings obtained from implementation of five tasks on numbers are discussed in terms of mathematical opportunities occurred during the implementations and how preservice teachers attended to those opportunities. The analysis of data revealed that preservice teachers noticed the majority of the mathematical opportunities occurred during the implementations. However, their respond for such opportunities were mostly in the form of orienting students for correct answers rather than eliciting their conceptual understanding.

The didactic transposition of the asymptote and asymptotic behaviour
We examine the upper secondary education in Croatia framed in the ATD and concerning the knowledge about asymptotes. This body of knowledge spans across different domains, reveals with different tools and discourses and relates to relevant notions such as function and limit. The focus on the epistemological model makes our work universal. We emphasise three strands in the model for task design for prospective mathematics teachers within ATD.

RESIGNIFICATION OF THE USES OF THE DERIVATIVE IN A SCHOOL DESIGN: PREDICTION, TREND, AND APPROACH
We recognize that the uses of the derivative are excluded from the mathematical school discourse. Consequently, we elaborated a school design based on the uses of the derivative that emerge in a community of chemical engineers in the graphic analysis of the chemical compounds of electrical transformers. the design is applied to Chemical Engineering students with the aim of analyzing the valuing of uses of the derivative. The epistemology used comes from the consideration of a modelling category within the Socioepistemological Theory.

What is mathematics about to students?
Some see mathematics as a static discipline. Others see mathematics as a dynamic discipline. These contrasting views towards the nature of mathematics have an influence on teaching and learning. Teachers’ views of how mathematics can be learned in the classroom are based on their understanding of the nature of mathematics. These views about the nature of mathematics shape students’ perception of nature of mathematics.

Supporting elementary students learning data presenting
This research is focus on developing teaching material about data presenting based on realistic mathematics. Context and situation that is used in this material are using a data from Indonesian traditional food because it is such a familiar thing to students. From this teaching scenario, students can construct their ability to make a bar chart and a line chart. However, from this learning teaching process, students can learn and compare what the main characteristic of both kind of charts.

Specialized fractions division knowledge
This video pitch aims to present Anna’s works and interview as one of the sixty-four primary prospective teachers (PTs) involved in the study which examined the natures of PTs’ specialized fractions division knowledge (SFDK). To examine PTs’ SFDK, the model of SFDK (Wahyu, 2020) was referred to design the mathematics tasks and guide the data analysis. The findings show that Anna’s SFDK is yet connected and flexible. The implication to develop PTs’ SFDK will be discussed.

Implementing Mathematical Modeling for Emergent Bilinguals
This project, IM2EB, aims to address current gaps in knowledge and practice by enhancing mathematical teachers’ instructional capacity for EBs by designing rigorous mathematical modeling curriculum through teacher-researcher collaboration. The research questions guiding this work focus on changes in (1) teachers’ positioning EBs changed, (2) math teachers’ quality of mathematical instructions (3) EBs’ mathematical achievement through participating the teacher-researcher collaboration through co-developing, co-teaching mathematical modeling, and co-analyzing student data.

Considering the importance of teachers’ knowledge of the interaction between content and students, the current study investigates how pre-service mathematics teachers improve their knowledge of how students interact with the content through lesson study. Preliminary analyses showed that lesson study improves pre-service teachers’ ways of teaching in knowledge of how students interact with the content through two different ways; 1) by discussing how they learnt the content themselves, 2) by reflecting upon problems they encounter while teaching the content in an actual classroom setting. By doing so, they have the chance to eliminate the problematic aspects their students learning process.

This research project is focused on the investigation of the covariation of magnitudes in modelling real phenomena. We aim to extend the theory of the six levels of covariational reasoning of Thompson & Carlson (2017) in order to better describe those situations in which not only variables are involved, but also parameters. We aim at introducing and defining what we call a 2nd order covariation (Arzarello, 2019).

Student's Representation Ability to Communicate Problem-Solving Idea.
Representation is the ability that is needed to help better communication. Such that representation is related to communication ability. However, most students did not seem aware of mathematic symbols and solving the problems procedurally. Therefore, I decided to analyze the Student's representation ability to communicate their problem-solving idea.

A new policy demands PISA-like mathematics problems given to improve knowledge of literacy and numeracy as well as life skills in the Covid-19 pandemic. However, there have not been any learning resources that provide numeracy problems at schools or bookstores with the context of Covid-19. It is important to design a learning environment that provide numeracy problems using the context of COVID-19. This needs to be done to familiarize students with numeracy problems using the context of COVID-19 to improve their performance at the international level like PISA.

Profiling Context-based Mathematics Tasks Developed by Novice PISA-like Task Designers
This study aims to report the profile of context-based tasks developed by Indonesian student teachers. Data were collected from 124 items of mathematics tasks designed by 15 student teachers from seven universities in Indonesia submitted to the authors within a developmental research. The characteristics of tasks were measured in terms of three dimensions of problem generation (plausibility, sufficiency of information, and complexity), task profile (content, context, and process), level of context use, task format, and language issue.
