Coherent Elastic Neutrino-Nucleus Scattering
Authors: Scholberg Kate 
Published: March 2020

Abstract
Coherent elastic neutrino-nucleus scattering (CEvNS), the gentlest kind of interaction of a neutrino with an entire nucleus, was first predicted in 1974, but not observed until 2017 by the COHERENT collaboration. COHERENT and many other experiments are pursuing further measurements of this low momentum transfer process. We review the physics motivations for these measurements and prospects and status of current and future CEvNS experiments.

The effects of coherent neutrino mixing modulation by dark matter.
Authors: Marks W S 
Published: March 2020

Abstract
If there was a coupling between neutrinos and Dark Matter, then there could be an induced modulation of the neutrino-mixing spectrum analogous to the one produced by the MSW effect. The possible results of such a modulation have previously been investigated for the case where coherent effects cannot be isolated and the resulting pattern is de-coherent. This presentation is on an investigation that included coherent effects, which are relevant for very high-energy neutrinos as the wave-packets remain coherent over cosmological distances. The investigation found that observable coherent effects are produced by potentials several orders of magnitude smaller than the minimum potential required to produce an observable de-coherent effect, with the amount being baseline dependent. This extends the range of observability down to levels where an interaction is likely to exist, if it exists at all. The significant challenges in making such an observation will be covered.

A nonparametric method to evaluate significance of events in search for gravitational waves with false discovery rate
Authors: Yuzurihara Hirotaka , Mano Shuhei , Tagoshi Hideyuki 
Published: March 2020

AbstractDuring recent observation runs by LIGO and Virgo, tens of gravitational wave events have been observed. The gravitational wave network of LIGO/Virgo/KAGRA is planning longer observation runs with improved sensitivity in the future. In this situation, it is important to evaluate the significance of each event with reliable methods since we expect, as the observation period becomes longer and as the sensitivity of the detector improves, we expect to detect more false positive events with a given threshold for the false alarm rate. In this paper, we introduceq-valuewhich was first introduced by Storey[1], and is interpreted as False Discovery Rate (FDR). We introduce an algorithm to evaluate FDR in a non-parametric way, and apply it to publically available results of the analysis of the advanced LIGO O1 data, and find that we can obtain a better significance for GW151012 which has the lowest significance in the O1 events. For other events, we obtain consistent results already obtained by LIGO and Virgo.
The search for Majorana neutrinos with a background-free gaseous Xenon TPC at the tonne scale
Authors: Monrabal F. 
Published: March 2020

Abstract
The next generation of neutrinoless double beta decay search experiments aims to reach sensitivities to this half-life of the process up to 1028 years. This will require tonne scale detectors with almost no background in their region of interest, which represents a large improvement with respect to current technologies. With this scenario, the NEXT collaboration presents two parallel developments: NEXT-High Definition and NEXT-Barium atOm Light Detection. The first is based on the incremental improvement of the current pressure gas xenon technology, and the second is based on the use of a barium tagging technology.

Abstract
Ambient neutrons are one of the most serious backgrounds for underground experiments in search of rare events. The ambient neutron flux in an underground laboratory of Kamioka Observatory was measured using a 3He proportional counter with various moderator setups. Since the detector response largely depends on the spectral shape, the energy spectra of the neutrons transported from the rock to the laboratory were estimated by Monte-Carlo simulations. The ratio of the thermal neutron flux to the total neutron flux was found to depend on the thermalizing efficiency of the rock. Thus, the ratio of the count rate without a moderator to that with a moderator was used to determine this parameter. Consequently, the most-likely neutron spectrum predicted by the simulations for the parameters determined by the experimental results was obtained. The result suggests an interesting spectral shape, which has not been indicated in previous studies. The total ambient neutron flux is

How using comics can assist in determining the students’ learning of distance-time graphs
Authors: Azamain M S , Shahrill M , Musa N K H , Batrisyia I 
Published: March 2020

Abstract
The art of teaching mathematics at all levels requires a lot of creativity and innovation from a teacher for the students to effectively grasp what they are taught. Teachers tend to devise various means always ensure that they understand the attention of a learner in mathematics lessons bearing in mind that some learners easily switch off in mathematics lessons. In this study, we explored how a teacher can effectively use comics while teaching upper secondary students the topic of Distance-Time Graphs. The research entails that problems exists among the mathematics areas where the students face a challenge in grasping the concepts they are taught and even lose concentration more quickly while the teacher is teaching thereby falsely conceptualising that mathematics is a difficult subject. The concepts involved in this paper are in concurrent to the existing literature that the use of comics is one of the ways to draw the attention of students while teaching them. An action research approach was adopted to determine whether students’ understanding of mathematics concepts in Brunei schools could be improved using comics. The problems that 38 Year 10 students encountered while learning Distance-Time Graphs have also been elaborated in this paper, and the methodology through which comics can be incorporated into the teaching and learning process in this area has also be shown for practical application in the Brunei secondary school. There is also an elaboration on how the research concerning the use of comics in teaching was conducted and how the hypothesis was analyzed and evaluated to have a positive outcome in the teaching and learning process.

Abstract
Preliminary research showed the learning trajectory of fraction in the school that could not facilitate students to reinvent fraction concepts. Therefore, this research aimed to produce a hypothetical learning trajectory (HLT) for teaching fraction using realistic mathematics education (RME). The HLT was developed with a design research that consisted of a cyclic process of preparing for the experiment, conducting classroom experiment, and performing retrospective analysis. This study involved 25 students SMPN 1 Timpeh, Indonesia. Data were collected through student activity sheets, videotaping, field notes, and interviews. The data analysis technique used descriptive analysis techniques. The result showed HLT for teaching fraction using RME that could be help all of levels students. This HLT helped students to reinvent fraction concepts through horizontal and vertical mathematical processes. Finally, the HLT facilitated students to make their own models from informal to formal and improved the interactions between students and teachers.

Published: March 2020

AbstractThis research aimed at developing a learning trajectory based on realistic mathematics education (RME) approach, for teaching number patterns to the students at grade eight junior high schools. The research employed design research approach proposed by Gravemeijer and Cobb. The activities of the research consisted of a cyclic process of preparing for the experiment, conducting the experiment, and retrospective analysis. The learning trajectory for teaching number patterns was designed during preparing for the experiment phase, and then it was validated by three math educators. It was tried out in a small group, followed by try out in a regular classroom during conducting the experiment phase. Retrospective analysis was conducted after each try out to improve the learning trajectory. 32 grade eight students of a junior high school in Padang were involved as the subjects of the research. Data were collected through observations, analyzing students’ works, videotaping, and test. Collected data were analyzed descriptively. Through this research we developed a RME-based learning trajectory for teaching number patterns. The learning trajectory reached the criteria of content and construct validity; reflected the state of the art RME, internally consistent, and potential to develop students’ reasoning. It also satisfied the criteria of practicality in which the learning trajectory worked as intended in the classrooms. The results of students’ works showed that the learning trajectory could also improve the students’ reasoning in learning number patterns.

Learning the relation between quadrilateral using geometry’s puzzle for blind students
Authors: Andriyani  , Juniati D 
Published: March 2020

Abstract
Geometry is one of the fields in mathematics that deals with the shape, size, and properties of space that doesn’t require prior skills like basic arithmetic. Although the model of geometry’s object familiar and found in everyday life, it doesn’t mean that geometry is easily learned by students, especially to blind students who have limited visualization. A quadrilateral is a geometry matter which in its learning is often emphasized in the use of formulas and memorization so that students don’t understand the concept of each shape and its relation with the other ones. So, this underlies the researcher to design a learning trajectory of the relation between quadrilateral using geometry’s puzzle based on direct experience of blind students. The purpose of this research was determining the role of learning the relation between quadrilaterals using geometry’s puzzle to help students understand learning quadrilateral concepts. The method used is design research with Gravemeijer and Cobb’s model that through three stages, i.e. preliminary design, teaching experiments, and retrospective analysis. This research describes how geometry’s puzzle in learning the relation between quadrilaterals contribute to the understanding of quadrilateral concepts for blind students of MTs Yaketunis Yogyakarta. The result of this research shows that geometry’s puzzles can help increase students’ understand the concept of each quadrilateral shapes through the construction of knowledge about the relation between quadrilaterals so that students don’t need to memorize the definitions or properties of each quadrilateral shapes and achieve the defined minimum completeness criteria, that is 70.

Abstract
The concept of function was a basic concept that students must understand in mathematics learning. This concept needs to be implicated through realistic mathematical learning with the ethnomathematics approach. The purpose of this study was to describe students’ ability to simplify the concept of function through realistic mathematical learning with the ethnomathematics approach. This was part of the research development. This stage was the prototype phase. We apply realistic mathematics learning with the ethnomathematics approach. The instrument of this research was the assignment sheet and the in-depth interview sheet by the researcher. Data was collected through task-based interviews. It was analyzed qualitatively. The results of this study were that students were able to simplify the concept of function through realistic problems based on “andun dance” culture. He simplifies the concept of mapping. For example, f was a function from set A to B, students were able to simplify the concept of function f with Df = A (domain function f was A). Also, being able to explain with various real examples and being able to show the position of the concept of function in a deductive structure of mathematics. The conclusion of this study was that realistic mathematics learning with ethnomathematics approach can be a vehicle for students to simplify the concept of function to be more meaningful.

Authors: Payadnya I P A A , Atmaja I M D 
Published: March 2020

Abstract
The aim of this study was to improve students’ mathematical critical thinking skills through the application of “What-If” learning strategies. This research was motivated by the lack of critical thinking skills of students in the Statistical Method I subject. Critical thinking skills are very important to bring someone to think and work carefully, sorting out relevant information, solving problems, and doing tasks on a bigger scale. This research is a classroom action research consisting of two cycles. The subjects of this study were class IIA students of Mathematics Education Study Program, Faculty of Teacher Training and Education, Mahasaraswati University Denpasar as many as 16 students in academic year 2018/2019. Data collection techniques used was observation, interviews, and tests. This study used 2 data analysis techniques namely qualitative analysis and quantitative analysis. Qualitative analysis uses models such as mathematical models and analyses that are carried out limited to data management techniques by performing descriptions. Quantitative data analysis measures the learning outcomes in the form of scores and percentages using a simple level of calculation such as average score and learning completeness percentage. The results of this study showed an improvement in students’ mathematical critical thinking skills from the first cycle to the second cycle. In the first cycle, the average score of students’ mathematical critical thinking skills was 71.125 with the learning completeness percentage only reached 62.5%. In the second cycle, the average score of students’ mathematical critical thinking skills increased significantly by 84.125 with the learning completeness percentage reached 87.5%. This study concluded that the application of “What-If” learning strategies can improve students’ mathematical critical thinking skills in the subject of Statistical Method I.
