Focusing on Data: Year 5 Students Making STEM Connections
Authors: Fitzallen Noleine , Wright Suzie , Watson Jane
Published: January 2021

Integrated STEM learning experiences provide the opportunity for students to make connections among the various disciplines. The outcomes for many STEM activities, however, are only reported for one discipline and provide little guidance for taking an integrated approach to learning in the classroom. This paper reports on a Year 5 STEM activity based on designing, making, and trialling seed dispersal devices. A focus on the data collected by the class and the subsequent graphical representations created during follow- up interviews, illustrates the way in which the students made connections to multiple STEM disciplines. The results indicate that Year 5 students have the capacity to use graphical representations of data to describe the performance of seed dispersal devices and base informal inferences about the performance of the devices on their knowledge of design, construction, materials, and flight from the various STEM disciplines.

Los Andes Libres es un fiel reflejo del entusiasmo patriótico que se senlía en Lima en los momentos en que se juraba la independencia y en los meses que siguieron. No ofrece mayor información sobre los acontecimientos, en cambio si es un trasunto de la reacción emocional causada por el ingreso del ejército libertador en Lima y el significado de la retirada realista. Podemos también observar, la influencia que la prensa de aquella época, tiene en la formación y el desenvolvimiento conceptual de determinadas ideas como las de libertad, patria, independencia, etc., que contribuyen poderosamente al desarrollo de la conciencia nacional, factor éste determinante en cualquier movimiento independentista.

Deciphering Organization of GOES–16 Green Cumulus, through the EOF Lens
Authors: Dror Tom , Chekroun Mickaël D. , Altaratz Orit , Koren Ilan
Published: January 2021

Abstract. A subset of continental shallow convective Cumulus (Cu) cloud fields were shown to have unique spatial properties and to form mostly over forests and vegetated areas, thus referred to as green Cu. Green Cu fields are known to form organized mesoscale patterns, yet the underlying mechanisms as well as the time variability of these patterns are still lacking understanding. Here, we characterize the organization of green Cu in space and time, by using data driven organization metrics, and by applying an Empirical Orthogonal Function (EOF) analysis to a high-resolution GOES–16 dataset. We extract, quantify and reveal modes of organization present in a green Cu field, during the course of a day. The EOF decomposition is able to show the field's key organization features such as cloud streets, and it also delineates the less visible ones, as the propagation of gravity waves (GW), and the emergence of a highly organized grid on a spatial scale of hundreds of kilometers, over a time period that scales with the field's lifetime. Using cloud fields that were reconstructed from different subgroups of modes, we quantify the cloud street's wavelength and aspect ratio, as well as the GW dominant period.
Simulating δ15N of atmospheric NOx in CMAQ version 5.2.1, based on 15N incorporated SMOKE version 4.6 and WRF version 4.0 for assessing the role atmospheric processes plays in controlling the isotopic composition of NOx, NOy, and atmospheric nitrate
Authors: Fang Huan , Michalski Greg
Published: January 2021

Abstract. Nitrogen oxides (NOx = nitric oxide (NO) + nitrogen dioxides (NO2)) are important trace gases that affect atmospheric chemistry, air quality, and climate. Despite the importance of NOx emissions, there are significant uncertainties in NOx emission inventories. After NOx from different sources being emitted into the atmosphere, its composition will change due to atmospheric processes. In this study, we used the nitrogen stable isotope composition of NOx (δ15N(NOx)) to trace the changes in δ15N values along the journey of atmospheric NOx, by incorporating 15N into the emission input dataset prepared from the previous companion research (Fang & Michalski, 2020) to run CMAQ (the Community Multiscale Air Quality Modeling System). The simulated spatiotemporal patterns in NOx isotopic composition were compared with corresponding atmospheric measurements in West Lafayette, Indiana, USA. The results indicate that estimating of atmospheric δ15N(NOx) using CMAQ shows better agreement with observation than using SMOKE (Sparse Matrix Operator Kernel Emissions), due to the consideration of mixing, disperse, transport, and deposition of NOx emission from different sources.
Flood spatial coherence, triggers, and performance in hydrological simulations: large-sample evaluation of four streamflow-calibrated models

Published: January 2021

Abstract. Floods cause extensive damage, especially if they affect large regions. Assessments of current, local, and regional flood hazards and their future changes often involve the use of hydrologic models. A reliable hydrologic model ideally reproduces both local flood characteristics and spatial aspects of flooding under current and future climate conditions. However, uncertainties in simulated floods can be considerable and yield unreliable hazard and climate change impact assessments.
This study evaluates the extent to which models calibrated according to standard model calibration metrics such as the widely used Kling–Gupta efficiency are able to capture flood spatial coherence and triggering mechanisms.
To highlight challenges related to flood simulations, we investigate how flood timing, magnitude, and spatial variability are represented by an ensemble of hydrological models when calibrated on streamflow using the Kling–Gupta efficiency metric, an increasingly common metric of hydrologic model performance also in flood-related studies. Specifically, we compare how four well-known models (the Sacramento Soil Moisture Accounting model, SAC; the Hydrologiska Byråns Vattenbalansavdelning model, HBV; the variable infiltration capacity model, VIC; and the mesoscale hydrologic model, mHM) represent (1) flood characteristics and their spatial patterns and (2) how they translate changes in meteorologic variables that trigger floods into changes in flood magnitudes.
Our results show that both the modeling of local and spatial flood characteristics are challenging as models underestimate flood magnitude, and flood timing is not necessarily well captured. They further show that changes in precipitation and temperature are not always well translated to changes in flood flow, which makes local and regional flood hazard assessments even more difficult for future conditions.
From a large sample of catchments and with multiple models, we conclude that calibration on the integrated Kling–Gupta metric alone is likely to yield models that have limited reliability in flood hazard assessments, undermining their utility for regional and future change assessments. We underscore that such assessments can be improved by developing flood-focused, multi-objective, and spatial calibration metrics, by improving flood generating process representation through model structure comparisons and by considering uncertainty in precipitation input.
Evaluating Spatiotemporal Patterns and Trends of Drought in Japan
Associated with Global Climatic Drivers

Published: January 2021

Abstract. Drought disasters, such as water scarcity and wildfires, are serious natural disasters in Japan that are also affected by climate change. However, as drought generally has widespread impacts and the duration of drought can vary considerably, it is difficult to assess the spatiotemporal characteristics and the climatic causes of drought. Therefore, to identify the drought homogeneous regions and understand climatic causes of regional drought over Japan, this study provides a spatiotemporal analysis for historical droughts patterns and teleconnections associated with global climatic drivers. The trends of meteorological elements, which are the basis of drought index calculation, was first assessed. Then, drought characterized by the Self-calibrating Palmer Drought Severity Index (scPDSI) was investigated. Trends and patterns of drought were identified through the trend-free pre-whitening Mann-Kendall test and distinct empirical orthogonal function. The continuous wavelet transform and cross wavelet transform together with wavelet coherence were utilized to depict the links between drought and global climatic drivers. The results are described as follows: (1) the trends of precipitation were insignificant. However, temperature and potential evapotranspiration increasing trends were detected over Japan; (2) the drought trend over Japan varied seasonally, increasing in spring and summer and decreasing in autumn and winter; (3) two major subregions of drought variability—the western Japan (W region) and most of the northernmost Japan near the Pacific (N region) were identified; (4) wildfires with large burned area were more likely to occur when the scPDSI was less than −1; and (5) the North Atlantic Index (NAOI) showed the strongest coherence connections with Distinguished Principle Components-1 among four climatic drivers. Additionally, Distinguished Principle Components-2 showed stronger coherence connections with NAOI and Arctic Oscillation Index. This study is the first to identify homogeneous regions with distinct drought characteristics over Japan and connect the drought in Japan with the global climatic drivers.

Authors: Marchant Orrego Teresa , Recart Herrera Isidora
Published: January 2021

En educación básica existe la necesidad de trabajar en dominar destrezas tales como desarrollo cognitivo, lectura y escritura. Fundación Educacional Arauco, una institución privada que lleva 15 años realizando programas de perfeccionamiento docente a profesores de escuelas básicas municipalizadas de la VII y VIII Regiones del país, describe una modalidad de trabajo para apoyar a alumnos de rendimiento regular (alumnos con logros apenas suficientes en una destreza, es decir una categoría bajo lo esperado para su nivel). Se trata de focalizar esfuerzos en estos niños, en una destreza específica, durante ciertos períodos de tiempo, a fin de acercar sus niveles de aprendizaje a lo esperado, sin descuidar el trabajo con los otros alumnos del curso. El foco está en entregar metodologías, contenidos y materiales a los profesores para trabajar con el curso completo, agrupado en 2 ó 3 niveles, y hacer un monitoreo cercano a su práctica docente mediante un trabajo conjunto especialista-profesor al interior de la sala de clases.

En este artículo se describe como se trabaja esta estrategia en general, se detalla como se implemento en el área de la lectura en 18 escuelas básicas de una comuna en la VIII Región durante los años 2000 a 2003, y se presentan algunos resultados obtenidos. Se pudo constatar que hubo un progreso estadísticamente significativo, en ambos grupos de alumnos, tanto en calidad como en velocidad de lectura oral después de la aplicación de la estrategia.

Published: January 2021

Higher education institutions (HEIs) contribute substantially to the quality of life (QoL) of the regions where they operate and to the progress and sustainable development of a country. This research intends to have an innovative approach in the study of the HEIs’ impact on the QoL of regions by taking into consideration both qualitative and quantitative indicators. This study aims to identify, collect and systematize indicators that can be used to measure the impact of HEIs on QoL: on the demand-side based on expenditure (inputs) and the knowledge-based supply side (outputs). For accomplishing this, the authors carried out a literature review, an analysis of available statistical data in Portugal and interviews for the analysis and consolidation of indicators. The results will facilitate the measurement of the HEIs’ impact on QoL and regions and allow the elaboration of a matrix of reliable indicators, which will hopefully assist in the definition of new higher education policies.

Published: January 2021

The study consisted of a survey and field experiment to observe the impact of behavioural nudges on an individual’s attitudes and accuracy on waste sorting. The survey conducted on 203 students of the University of Peradeniya, and then the field experiment within the university premises. The responses to the survey revealed that the participants having a negative attitude toward the usual waste disposal and sorting practices. Also, the majority of the respondents preferred non-monetary incentives as an effective strategy to motivate individuals to improve the accuracy of waste sorting. Then the participants are given nine strategies as separate behavioural nudges to improve the waste sorting behavior. The responses are highly varied and the majority prefer to use a combination of different colours and detailed labels as a motivational strategy. Thus, the preferred strategy was examined at the faculty premises throughout three stages and tested three hypotheses. Findings revealed that the strategy improves the accuracy, and supports the university community for proper waste sorting practices. Further, it exposed that the detail labels and stickers are impactful than the color sensitivity of respondents.
A structural decomposition analysis for traffic demand assessment on a freight transport corridor
Authors: Pompigna Andrea , Mauro Raffaele
Published: January 2021

This paper deals with a Structural Decomposition (SDA) applied to the analysis of the freight traffic demand in an Input Output (IO) modelling context. After reviewing the basic definitions of IO models and some methodological refer-ences for their application in the freight transport field, the paper proposes the application of the SDA in the perspec-tive of a freight corridor. This application takes place downstream of an IO model that directly relates the quantities of goods transported along the corridor with the functioning of the reference economic system. Considering the evolution of tons annually transported in a certain time interval, the SDA model allows to isolate the specific effects related to: intensity of freight traffic typical of the corridor; technological structure of the production sectors; characteristics of the final demand in relation to its overall level, sectoral structure and allocation between components. The SDA model is applied to a case study considering the total volumes of goods annually in transit at the Brenner pass between 2000 and 2014. The evaluation of the polar forms of the multiplicative decomposition and their geometric mean allow to quantify the effects of each factor on the variation of the tonnage in terms of indexed value, absolute variation and percentage contribution compared to the base year (2000). The relative influences on freight traffic at the Brenner pass are therefore highlighted, both in terms of total volumes transited and impacts attributable to each of the decomposi-tion factors introduced, with particular evidence also in the event of periods of economic and financial crisis. The SDA specified in the paper and the related case study provide useful elements for studying the traffic demand of goods through a freight corridor, helping in outlining the effects of the different driving forces related to the economic system and affecting freight transport demand trends.
TRADUZIR É UM ATO POLÍTICO? ALGUMAS CONSIDERAÇÕES A PARTIR DE WALTER BENJAMIN
Authors: Pinho Isabela
Published: January 2021

O presente artigo tem em vista a reformulação da língua pura no ensaio “A tarefa do tradutor” de Walter Benjamin, com o objetivo de indicar, como apontamento a ser desdobrado, a relação entre tradução, linguagem e política. A tradução concebida não como mera transcrição de uma língua para outra, nem como comunicação do sentido da obra original, mas como afinidade supra-histórica (überhistorischer Verwandtschaft) entre as línguas históricas implica outra experiência da linguagem. É a experiência da comunicabilidade da linguagem para além de seu caráter comunicativo e para além das línguas históricas que ensejará, como apontamento, um questionamento sobre a dimensão política da tradução. Dividido em duas seções “tradução: encontro amoroso entre línguas” e “tradução: para além das barreiras históricas das línguas” este artigo trabalha tanto uma metafórica feminina como uma metafórica política encontradas no ensaio benjaminiano.

WALTAR BENJAMIN, TEÓRICO DO TRANSUMANISMO?
Authors: Rodrigues Victor César Fernandes
Published: January 2021

O presente artigo tem a pretensão de oferecer uma interpretação possível acerca de alguns postulados de Benjamin acerca do capitalismo como religião, tentando vincular o tema do transumanismo da singularidade como uma de suas contrapartes ilustrativas, mas de modo algum única. Mapearemos parte por parte do fragmento de O capitalismo como religião, tentando sondar as aberturas que suscitem essa determinada articulação. Em seguida, faremos um apanhado extremamente pontual acerca da filosofia do movimento transumanista, dando especial ênfase ao transumanismo da singularidade, como uma das versões do movimento segundo a qual mais nos parece afim com o caráter antecipatório na visão de Benjamin acerca da “religião do capital”, demonstrando haver certos nexos reflexivos com a “religião da máquina” propagandeada por essa vertente e, essencialmente, da versão com que a fusão entre humanos e máquinas encampa seus discursos.
É POSSÍVEL UMA REFORMULAÇÃO DO IMORALISMO COGNITIVO DE KIERAN?
Authors: Pozza Gustavo Luiz
Published: January 2021

Dada a tendência de que se avalie moralmente a experiência estética, a filosofia contemporânea tem desenvolvido linhas de avaliação ético-estéticas que propõem soluções divergentes para o equilíbrio desses valores. Matthew Kieran propõe uma corrente que defende o imoralismo como uma associação entre falhas morais e méritos estéticos, bem como um imoralismo cognitivo, no qual o espectador, pela vivência da imoralidade no universo ficcional da obra, pode questionar seus valores morais. Entretanto, a proposta de Kieran não nega o eticismo, passo necessário para que se suprima um relativismo moral derivado da moralização, e acaba por retornar ao problema da bifuração forma-conteúdo do esteticismo. Diante desses problemas resultantes dessa formulação do imoralismo, propõe-se uma nova formulação do imoralismo cognitivo que negue o moralismo sem resultar na proposta amoral do esteticismo e que, ainda afirme o cognitivismo.
AS INTERSEÇÕES ENTRE O RACISMO ESTRUTURAL E A NECROPOLÍTICA
Authors: Santos Thiago Teixeira
Published: January 2021

Ao atravessarmos as discussões sobre o Racismo Estrutural e a Necropolítica nos aproximamos de uma reflexão acerca das constituições da cena política que demarca espaços de vida e de morte. A problematização do biopoder, aos moldes de Mbembe, demarca a construção do sujeito alinhada às insígnias de subjetividade que se distanciam, como ventilação de uma concepção colonizada de mundo, dos corpos negros. A constatação de uma soberania que se alinha ao interesse perverso de matar aqueles que são constituídos como exceção se liga ao processo permanente de criação de um inimigo comum. Esse inimigo é mantido através de um interesse hegemônico e ideológico que desliza se enraíza nas realidades sociais. A formação de um processo simbólico e valorativo que forja as nossas consciências, faz com que sejamos capazes de reproduzir discursos, práticas e valores de exclusão da população negra ventilando, assim, as determinações de um estado colonizador e genocida.
A NEGAÇÃO DA ALTERIDADE E A NECROPOLÍTICA
Authors: Souza Lourival Robty Santos de , Barreto Lauro Barros
Published: January 2021

Esta pesquisa surge diante do filosofar e da intuição investigativa que percebe as estruturas políticas em estado de corrosão perante a alteridade, desde a perspectiva do filósofo Emmanuel Levinas, e o cenário da necropolítica denunciado por Achille Mbembe diante de sua crítica à sociedade democrática e escravagista. Serão retratadas realidades contemporâneas de vida humana, como o paradigma da violação da integridade física, moral e da própria vida em si diante do cenário da população carcerária negra. O mecanismo da necropolítica oferece relações em estado de ruína, com sua política de morte, a sua assistência para fortalecer as desigualdades, exemplificado na população carcerária, e a violência institucionalizada. Ao adentrar nas experiências contemporâneas de destruição humana, faz-se necessário, identificar os envolvidos na contenda como sujeitos de negação ou afirmação da alteridade. O objetivo desta investigação será analisar a negação da alteridade e os mecanismos da necropolítica que violam e ceifam a vida.

Published: January 2021

Public concern about the environmental impact of economic activities has significantly increased around the globe in recent years. Within the scope of unlawful acts, environmental delicts are among the most serious ones in terms of environmental impact, the consequences of which directly affect the quality and development of agriculture as the main branch of economic activity. The issue of environmental protection and liability can be approached from different perspectives, and the focus of the present research will be on the analysis of environmental delicts committed by legal entities, taking into consideration the importance and role of these entities in agriculture. In addition to general assumptions on legal regulation of the liability of legal entities, the authors also presented the results of research on legal entities reported, charged, and convicted for environmental delicts in the Republic of Serbia in the period from 2010 to 2017, with a special emphasis on the analysis of results obtained in the abovementioned research areas for the territory of AP Vojvodina.
1951-1952 competition for the Monument to the fallen Jewish soldiers and victims of fascism in the Sephardi cemetery in Belgrade
Authors: Stipić Davor
Published: January 2021

In their wish to preserve the memory to the compatriots who lost their lives in the Holocaust, the Jewish community in Yugoslavia started erecting monuments to Jewish civil victims and fallen soldiers as early as the first few post-WWII years. The Monument to the Fallen Jewish Soldiers and Victims of Fascism put up in the Sephardi cemetery in Belgrade in 1952, potent with artistic and political significance, stood out from the rest of the monuments of the period. It was dedicated to all the Jews from the Socialist Republic of Serbia who lost their lives in the World War II. The purpose of this article is to analyse the competition for the design of the monument by examining the documents from the Archives of the Jewish Historical Museum in Belgrade, thus making a contribution to the research of the culture of Holocaust remembrance in the Yugoslav Socialism, but also to show artistic, social and ideological aspirations of the time when, after the Cominform schism, Yugoslavia was at political crossroads. By exploring the symbolism and aesthetic values of this work, the research presented in this paper attempts to enhance the understanding of architect Bogdan Bogdanović's early creative efforts.

Published: January 2021

Objective. The aim of this study is to determine the quality of accredited education on the topic of gender-based violence to health care professionals, health and professional associates in the Republic of Serbia. Methods. A search of a database of accredited continuing education programs published on the website of the Health Council of the Republic of Serbia for the period between January 2010 and July 2019. identified programs using the keywords "violence", "family" "gender-based". The ch2 test was used to examine the differences between the independent variables versus the dependent variable. Results. This study showed that two thirds of the training was intended for health care professionals, only while health care workers, health and professional associates were allocated for every seventh education. If the type of institution is observed, it can be noticed that twice as many programs are accredited by civil society organizations in relation to the number of programs accredited by health institutions. Considering the time period in which the programs are accredited, a trend of increasing number of programs can be observed. Among the accredited programs, national courses accounted for 42.6% of the accredited programs while every other program was free. There is a statistically significant difference between educations organized by different types of institutions in relation to the type and cost of education. Conclusion. Although in the observed period there is an increasing trend in the number of accredited programs dealing with gender-based violence, there is still room to improve the quality of continuing education in terms of increasing the number of trainings with an interactive method of work, trainings aimed at different profiles of health professionals and health and professional associates, as well as free on line trainings.

Objective. Coxsackievirus B (1-6) infections are the common infections of children and adults. Clinical manifestations include fever, aseptic meningitis, pleurodinia, myocarditis, gastroenterocolitis, maculous exanthem. The clinical course of the infection is influenced by the characteristics of the host, as well as the virus serotype. The pathogenesis of the diseases is explained by the immune mediated mechanism and the direct cytotoxic effect of the virus. Methods. Retrospectively analyzed virus serotype, clinical and biochemical data in patients with coxsackievirus B (1-6) infection. Patients who had an unclear febrile condition for more than six months were tested for autoantibodies. Results. We examined a total of 378 patients with coxsackievirus B (1-6) infection (302 women, 76 men), age 19 to 79 years. The dominant symptoms were weakness, elevated body temperature, fatigue and muscle aches. In 55% the clinical course was fever of unknown origin, in 13% myalgia/pleurodinia, 9% acute gastroenterocolitis and acute myocarditis/ pericarditis, 2% aseptic meningitis, 2.4% respiratory disease, 3% acute pancreatitis and 1% diabetes mellitus. Autoantibodies were detected in 69% of patients with fever of unknown origin. Antinuclear antibodies were most common, in 67%. Serotype B2 had 36% of these patients. Serotype B2 had 36% of these patients and serotype B4 had 14%. Conclusion. The most common clinical form of coxsackievirus B (1-6) infection is an fever of unknown origin caused by a B2 serotype of the virus. In most of these patients, an elevated titre of antinuclear antibodies can be detected.
Alligation

Published: January 2021

In consideration of the almost absolute assurance with which the authors of arithmetics have omitted the topic of alligation from their texts for the past generation or two, I will confess that it is with some timidity that I am undertaking to show that this old-fashioned, illogical process greatly simplifies many of the calculations of a special but a rapidly increasing class of men, namely the industrial chemists.

Language Development in Mathematics through Vocabularies
Authors: Alexander Burton F.
Published: January 2021

The responsibility of developing and improving the general and technical vocabularies that are associated with elementary mathematics lies in the hand of the subject teacher. Moreover, in connection with these two principal types of vocabularies, four integral components of each should be considered, viz.: the writing, the reading, the speaking, and the potential or marginal vocabularies. A learning situation can be easily influenced by a pupil's knowledge of basic English.
The Geometry of the Pentagon and the Golden Section
Authors: Baravalle H. v.
Published: January 2021

The Geometry of the Pentagon has become almost a foster-child besides other chapters of geometry, as for instance the geometry of the triangles or of the quadrilaterials. Considering terminologies, we find the whole field of trigometry deriving its name from the geometry of triangles and the “quadrature of areas” (quadratum = square) from the regular representative of the quadrilaterals, all units for measuring areas being also squares.
Curriculum Trends in High School Mathematics
Authors: Breslich E. R.
Published: January 2021

The problem of selecting and organizing instructional materials for high school pupils is as old as the high schools. When these schools came into existence the courses in algebra and geometry then offered in the colleges were moved downward into the lower schools. Unfortunately these subjects had been organized by college instructors for college students and were in no sense planned to meet the needs and abilities of high school pupils. It was to be expected, therefore, that they would need to undergo considerable reconstruction. To the solution of this problem the mathematics teachers of the nineteenth century have devoted a great deal of time and effort.
Is General Mathematics in the College on Its Way Out?

A Technique for Giving Meaning to Elementary Mathematical Operations
Authors: Lazar Nathan
Published: January 2021

Very few words in the English language have been used so frequently and so loosely in the recent literature on the teaching of mathematics, as the words “meaning,” “significance,” “insight,” and “understanding.” It would, of course, be a distinct service to clear thinking in general and to that of mathematical pedagogy in particular to analyze the various penumbra of meanings associated with each of the above words. The purpose of this article is, however, much more modest and far more restricted: It aims to show how the full meaning of mathematical operations can be made clearer to the immature student by the simple device of asking him to answer a set of three questions to be described below.
A Comparison of Traditional Teaching and Personalized Teaching in Ninth Grade Algebra
Authors: Schultz Margaret , Ohlsen M. M.
Published: January 2021

It is an accepted fact that the whole individual functions as he learns. The pupil's feelings as well as his intellectual analysis of the mathematical problems come into play in the learning process. Emotional blocks, feelings of insecurity, conflict at home, and all other personal problems affect the pupil's ability to perform in the classroom. Evidently there is something in the learning process that penetrates deeper than mere memorization of facts.
The Blight of Mathematical Slang
Authors: Stewart Lurline
Published: January 2021

As a background for my remarks, let me say that my teaching career includes the teaching of mathematics in a saw mill town where one half the people owned the town and the other half worked for the first half; in an agricultural high school where the majority of the children came from farm homes; in a smaller rural community in perhaps the poorest county in the state; in a town of around 1200 where culture and civic pride are the order of the day; in one of the largest state universities in the south; and finally in one of the best junior colleges in Mississippi. Students in each of these schools use mathematical slang, and I cannot say that I have found it any more prevalent in one place than another.

Installment buying is again beginning to go on a rampage as it, did in the 1920's. A recent news release estimates an increase of $170,000,000 per month. A glance at a daily newspaper or a few hours spent in shops where radio phonographs, automatic washers and cars are sold, will reveal the amazing and alarming trend.

Meaningful Division
Authors: Smith Rolland R.
Published: January 2021

Readiness for number concepts and number relationships is not so much a matter of chronological age as it is of experience. Of course, the pupil of the fourth or fifth grade can be taught division when it would be impossible to do this with the average first grade pupil. But it is not his age that makes this possible so much as it is the fact that having lived longer he has had time to gain greater experience with numbers. If we could blot out all the number experiences of a ten or eleven year old child, the chances are that he would not be more ready for division than his younger brother.
The Content of a Course in General Mathematics—Teachers’ Opinions
Authors: Brown Kenneth E.
Published: January 2021

My interest in general mathematics was stimulated several years ago when I attempted to teach general mathematics to seventy girls who, expecting to be primary teachers, saw no need for mathematics. Since that time I have given special attention to the attempts of other teachers to fill the mathematical needs of that large academic group who are not specializing in mathematics or its applied fields.

Observations on Attitudes of Young Children Toward Mathematics
Authors: Plank Emma N.
Published: January 2021

A study of the development of concepts of number was undertaken to throw light on the learning processes involved. The materials used were mainly those devised by Montessori. The twenty children who served as subjects ranged from kindergarten to the sixth grade. In order to study the factors contributing to failure in arithmetic and to find out whether they are specific and different from causes of failures in other fields, children were chosen who were successful in all other school subjects. It was also hoped to see whether different teaching methods might resolve the difficulty.
