The study was undertaken to determine the extent of integration of Information and Communication Technology (ICT) to Mathematics teaching and learning processes among Junior and Senior High School teachers in the Division of Tanauan City. Further, the research also identified various challenges encountered in ICT-based teaching and learning Mathematics. This study used mixed method of research to obtain the necessary data in the conduct of this research. Specifically, the researchers used survey questionnaire, interview, and focus group discussion with the 77 junior and senior high school Mathematics teachers from the division of Tanauan City. The actual number of respondents was determined using Raosoft sample size determination at five percent margin of error and used stratified random sampling. The Weighted Mean, Frequency Distribution, Percentage, Mean, Standard Deviation, and T-test were the statistical tools used to analyze the data gathered. Based on the findings of the study, majority of the respondents were female, bachelor’s graduate, from teachers I to III, 15 years below in the service and not active in the ICT – related seminars attended. Most of the respondents use technology in writing lesson plans, in computing students’ results and, in teaching the lesson through power point presentations. However, due to the lack of resources and little fund from the MOOE, the respondents rarely use telecommunication devices such as cable, satellite, fax-machine etc. to interact with pupils. There is a significant difference between the extent of the use of ICT in teaching and learning Mathematics and years in teaching. Different challenges like lack of ICT facilities, confidence in the use of ICT and lack of trainings attended were the most commonly identified by the respondents. With the aforementioned, the researchers recommended that Mathematics teachers must be given more opportunities to participate ICT-based seminars and trainings.
Transition from Primary to Secondary School Mathematics: Students’ Perceptions
Authors: Attard Catherine 
Published: January 2021

During a longitudinal case study on engagement in Australian middle school years mathematics, 20 students in their first year of secondary school in Western Sydney, New South Wales, were asked about their experiences of the transition to secondary school in relation to their experiences of mathematics teaching and learning. Changes and disruptions in teacher-student relationships were a major cause of concern. This was due to fewer opportunities for teacher-student interactions and a heavy usage of computer-based mathematics lessons during the first months of secondary school. Findings indicate that a strong pedagogical relationship is a critical foundation for sustained engagement in mathematics during the middle years.

Authors: Zulkardi Zulkardi 
Published: January 2021

A new issue in education in Indonesia is the change of curriculum in 2013. This paper presents what are the changes in content, media, method, and evaluation of mathematics subject at the school levels. As informed by the minister of education and culture in the national newspaper, the changes in the primary school mathematics will connect and integrate with science. This might increase the understanding of students in both the concept of mathematics and the application of mathematics in their daily lives that is also related to science. Hence, mathematics teachers need a way to design meaningful learning materials to integrate the two subjects. It is called thematic-integrated approach or one intertwined among strands or subjects. This article will discuss these both approaches. The former is mentioned in the new curriculum while the latter is one of five characteristics of Indonesian Realistic Mathematics Education (PMRI). Then the current development of PMRI after 12 years of implementation and dissemination in Indonesia will be discussed. During this discussion it will reveal how to design and implement joyful and meaningful mathematics learning materials by using the Indonesia context or culture.

Authors: Prahmana Rully Charitas Indra 
Published: January 2021

The purpose of this study is to look at the role of using Mathematics GASING (Math GASING) to help students understand and master the addition concept from the informal level (concrete) to the formal level. The research method used is design research with a preliminary design, teaching experiments, and retrospective analysis stages. This study describes how the Math GASING made a real contribution for students understanding of the concept of addition. The whole strategy and model that requires students to discover, to describe, and to discuss during the construction phase demonstrates how students can use their initial understanding of the addition concept. The stages in the learning trajectory have an important role in understanding the addition concept from informal level to formal level and also make the study of mathematics more easy, fun, and enjoyable.
Inculcating Tsunami Awareness in a Mathematics Lesson: Improving Students’ Collaborative Problem Solving via Lesson Study
Authors: Khalid Madihah , Ali Dk Haslinah Pg. Haji 
Published: January 2021

The past two cycles of PISA have reflected the demands of the skills and competencies that many countries desire their future generations to possess. Among these competencies, students’ financial literacy, problem solving, and communication skills have emerged to be as important as their reading and quantitative literacy (OECD, 2013). Problem-solving, along with other 21st century skills can be inculcated in the students by using the problem-solvingpedagogy. However, teachers who are not used to teaching mathematics via problem solving need to experience the pedagogy themselves and this can be best achieved by implementing Lesson Study. A Lesson Study research study was conducted to look at collaborative problem solving in the teaching of the topic on “rate” to year 5 students. Results showed that students benefited from their lesson in terms of increased knowledge of the problem context and theability to apply knowledge of rates in finding the best solution that the problem posed. Consequently, Lesson Study was found to help enhance teachers’ pedagogical content knowledge. It helped them produce effective lesson plans that incorporated student-centred authentic lessons that also integrated values, use of technology and students’ creativity in problem solving.
Re-engaging with Primary Mathematics Through Sustained Professional Development: A Case Study
Authors: Attard Catherine 
Published: January 2021

This paper reports on aspects of a case study of sustained professional development to improve teacher and student engagement with mathematics. Teachers from Grades 3 to 6 in one Western Sydney primary school were involved with a professional development program over the course of 18 months. Prior to this, the teachers limited opportunities to engage with any mathematics-related professional development. The professional development program resulted in improved teacher engagement and the development of a community of practice within the school. Findings from the study align with recommendations from literature that teachers must be provided with opportunities for continuing professional development that is self-nominated and focused on individual needs as well as group needs.
Mathematics Literacy: An Australian Perspective and Experience
Authors: White Allan Leslie 
Published: January 2021

A brief listing of five different types of mathematical literacy is provided. The definition used by the Program for International Student Assessment (PISA) is selected and some brief remarks are provided on this program. The performance of Australian students is examined which shows that at the beginning of the new century 2000, Australian educators were feeling comfortable and reasonably satisfied with student performance but by 2016there was great concern over a consistent decline. The reasons for this decline are briefly discussed with the focus on Australian governmental policies that followed the directions of reform in the United States and Great Britain, and what has been labelled GERM. Current policies have been tried and failed and it is time to look for alternatives. While it is not wise to just copy the programs and policies of another country rather than adapt them due to differences in culture, population diversity, and other factors, nevertheless countries such as Finland can offer alternative paths to be explored. In Australia’s case it would also seem to be unwise to adopt policies and programs of countries who perform worse than it.

The goal of this study is to determine the effects of inquiry learning and discovery learning upon learning achievement of junior high school students viewed from spatial intelligence. The learning models compared were inquiry learning, discovery learning, and classical model. This study used a quasi-experimental approach with a 3 x 3 factorial design. The population was all students Grade 8 of junior high school in Solo. The sample used a stratified cluster random sampling strategy which consisted of 260 students, divided into three groups, namely: 86 students in experimental group 1, 86 students in experimental group 2, and 88 students in control group. The instruments used included a mathematics achievement test and a spatial intelligence test. The data analysis used the two-way multivariate analysis of variance. The results of this study are as follows: (1) inquiry learning and discovery learning gave better learning achievement than the classical model, while inquiry learning and discovery learning resulted the same learning achievement, (2) students with high spatial intelligence had similar learning achievement with those with middle spatial intelligence, and (3) students with high and middle spatial intelligence had better learningachievement than students who had low spatial intelligence.

Authors: Nugraheni Theresia Veni Tri , Jailani Jailani 
Published: January 2021

Continuing Professional Development (CPD) contributes to teacher competencies, teaching practice quality, and student achievement. Based on a literature review, we found that there were three aspects of CPD. The CPD aspects that we found were: knowledge development; skill development; and knowledge dissemination. In this study, we focused on describing:(1) the CPD implementation, and (2) the barriers faced by senior secondary school mathematics teachers in Kulon Progo Regency in conducting the aspect of knowledge development. This type of study is descriptive research using a mixed method with convergent parallel design. The research subjects were all senior secondary school mathematics teachers in Kulon Progo Regency who participated in The Indonesian Teacher Competency (Uji Kompetensi Guru) in 2015 and 33 teachers were selected. Data werecollected through a questionnaire, documentation, and interviews, and analysed using descriptive techniques. The results showed that the CPD implementation in the aspect of knowledge development of senior secondary school mathematics teachers in Kulon Progo Regency was poor. The greatest barriers experienced by teachers related to conducting the aspect of knowledge development were an overwhelming workload, lack of selfmotivation, and inadequate place and time. Based on these findings, we suggested that teachers needed to be helped to develop their understanding and awareness of how CPD can improve their competencies, teaching practice quality, and student achievement. We also suggested that the government and stakeholders should encourage and facilitate teachers to participate actively to CPD activities that reach out teachers’ need.

Published: January 2021

While most of the existing literatures deal with hijab in the context of clothing, this article focuses on hijab as the bulkhead between men and women. I examine how hijab is understood, is indoctrinised, and is applied in activities conducted by Wahdah Islamiyah.
This qualitative research was conducted in Makassar as the center of Wahdah Islamiyah Organisation in Indonesia. It involved 12 informants, consisting of evelen akhwat and an ikhwan. Their age ranging between 22 and 50 years, and from various statuses, from research and development coordinator, active cadres, to ex-staff official at Wahdah Islamiyah. Data was collected using in-depth interview and observation.
The study indicates hijab in the context of Wahdah Islamiyah is divided into three, clothing hijab, heart hijab, and barrier hijab. Even though these three tpoes of hijab is associated with the interaction manner between ikhwan and akhwat, each has its own uniqueness. While clothing hijab is related to body cover from head to toe; heart hijab is associated with how hijab is applied in everyday life; barrier hijab is related to the barrier between ikhwan and akhwat in their social interaction. In Wahdah Islamiyah, hijab has been introduced from the beginning dam is internalized in tarbiyah, from the basic to the advance level, from the introduction, understanding, the application of hijab. In teraction between ikhwan and akhwat is always insulated by hijab. There are a number of strategy to limit the interaction behind the hijab, and they are using email, connection letter, social media (such as Whatsapp), text messages, etc. A number of activities that involved ikhwan and akhwat have to employ barrier hijab such as musyawarah, study, tarbiyah and tahsin, walimah, and they are using barrier hijab in such social interaction. It is argued in this article that hijab pembatas plays a significant role in Wahdah Islamiyah activities that involve ikhwan and akhwat.

Published: January 2021

Internet users are growing rapidly from time to time throughout the world, including Indonesia. As a result, consumer needs in terms of making payments have changed towards non-cash payments, namely e-wallets, which have become a huge potential in the e-commerce market. The preference for e-wallet transactions is increasing compared to using cash on hand. Most of its users are millennials, including students. This study examines knowledge related to the use of e-wallets and the reasons behind its use. The study involve ten college students, consisting of nine female students, and a male student whose age varies between 19 and 23 years. They come from various universities. Using qualitative approach, this study use in-depth interview as the primary data collection technique and secondary data obtained from relevant website. This research shows that e-wallet is not only understood as a place to store money electronically, but also as a digital payment. In Indonesia there are various e-wallet products. Among others OVO, Gopay, and DANA are the most popular ones. There are three aspects related to the students’ knowledge about e-wallet: source of information, features, and its use. Advertisements from social media, television, and transportation applications are the main sources of information about e-wallets. E-wallet offered various features, such as topping up, paying bills and pulses, and transferring and withdrawing from e-wallets to bank partners. E-wallet is used for a variety of purpose, such as to pay online transportation, to buy food/drinks, to pay bills, etc. There are three basic reasons why students use e-wallet as a payment method, namely because of the promos offered, convenience in transactions, and ease to operate. To attract people to use e-wallets, service providers must work with various merchants, whose promos are increasingly attracting users to use e-wallet for payment. In using e-wallets, students not only feel comfortable, but also convenience in payment because it can be done anywhere as long as the user is connected to the internet.
Keywords : Millenial generation, students, e-wallet, internet, cashless, and digital payment.
Simeon Poisson and the Stanley Cup Finals
Authors: Wagner Cate , Barr Erica , Spada Joseph , Joslin Cole , Sommers Paul M. 
Published: January 2021

The National Hockey League is a professional ice hockey league in North America currently comprised of 31 teams. Their seasons culminate with the Stanley Cup Playoffs. The top sixteen teams (eight in each conference) qualify for the playoffs. The conference champions face off in the final round, known as the Stanley Cup Finals. The authors show that goals scored per game in the Stanley Cup Finals follow a Poisson distribution. Using the results of all 438 Stanley Cup Final games played since 1939 (when the Finals became a best-of-seven series), chi-squared goodness-of-fit tests show that the observed distribution of goals scored per game by series winners, series losers, and game losers closely approximate a Poisson theoretical model. The combined number of goals scored by both finalists and goals scored by game winners do not

Published: January 2021

The authors examine the impact of President Donald Trump’s June 9, 2018 tweet disparaging Group of 7 (G7) summit host Canadian Prime Minister Justin Trudeau on Canada – United States border crossings over the Peace Bridge. The Peace Bridge is one of the busiest international border crossings in North America that connects Fort Erie, Ontario and Buffalo, New York. A regression analysis of daily automobile crossings between January 1, 2017 and December 31, 2019 (using seasonality dummy variables and controlled for year fixed effects) revealed a statistically discernible reduction in the number of crossings (both east into the United States and, to a lesser extent, west into Canada) seven, fourteen, and even thirty days after the tweet. Words have consequences.

Published: January 2021

The purpose of this study was to investigate the effects of cold work on the incipient pitting corrosion of 304L stainless steels (SS). The as-received (0%-CW) and 20% cold-worked (20%-CW) 304L specimens were corrosion tested in a salt-spray system with a solution of 3.5% simulated seawater for the exposure times of 12 h, 24 h, 48 h, 96 h, and 192 h to characterize the pitting corrosion behavior of 304L SS. Weight gain and microstructures were measured using a microbalance and electron backscatter diffraction, respectively. The dimensions of corrosion pits—depth, length, and width—were analyzed by confocal laser scanning microscope to elucidate the pit growth process. The analysis of the rust and pit features revealed that the degree of corrosion is more severe in the 0%-CW specimen than in the 20%-CW specimen.

and diabetic regulation, and complications in patients with diabetes mellitus
Authors: Konur Sevki 
Published: January 2021

IntroductionDiabetes mellitus (DM) is the most common endocrine disease. Increasing with a rapid acceleration, DM affects the society both financially and socially with its possible complications. Dyspeptic complaints occur in approximately 40% of DM patients. Dyspepsia in DM is a difficult condition to treat and requires patients’ frequent hospital visits. We aimed to examine a relationship between diabetic regulation and diabetic complications as well as endoscopic findings in patients with DM and dyspeptic complaints.Material and methodsPatients with a DM diagnosis from internal diseases outpatient clinic of our hospital who were followed-up between January 2019 and June 2020, and who underwent endoscopy for the upper gastrointestinal system were included. Diagnosis of DM was made according to the American Diabetes Association (ADA) criteria. Diabetic complications were questioned. A relationship between endoscopic and histopathological findings, glycated hemoglobin (HbA1c) level, and complications was investigated.ResultsA total of 105 patients, 61 (58%) females, were included into the study. In a comparison between the groups, there was no statistically significant difference between glycemic regulation and endoscopic findings and the presence of HP. Comparing diabetic complications, no significant difference was observed in patients with complications from the endoscopic findings, except for pangastritis. The presence of HP was similar in both groups.ConclusionsIt can be said that endoscopic findings and presence of HP are not closely related to glycemic control and complications in diabetic patients. However, these results should be supported by larger, multi-center, prospective studies.

Published: January 2021

BackgroundEarlier reports have shown that anxiety over the novel coronavirus may predict mental functioning during the pandemic. The objective of this study was to assess the links between persistent thinking about COVID-19, anxiety over SARS-CoV-2 and trauma effects. For the purpose of this study, the Polish adaptation of the Obsession with COVID-19 Scale (OCS) was imple-mented.Participants and procedureThe study involved 356 individuals aged 18-78 (58% females). In addition to OCS, the participants completed the following questionnaires: the Coronavirus Anxiety Scale and the Short Form of the Changes in Outlook Questionnaire.ResultsOCS was characterized by satisfactory psychometric properties (α = .82). Regression analysis indicated that persistent thinking about COVID-19 was associated with increased coronavirus anxiety and negative trauma effects. In addition, anxiety served as a partial mediator in the link between persistent thinking about COVID-19 and negative trauma effects.ConclusionsThe data obtained suggest that persistent thinking about the pandemic may be dysfunctional for mental health during the spread of the infectious disease.
