COGNITIVE TRANSFER OUTCOMES FOR A SIMULATION-BASED INTRODUCTORY STATISTICS CURRICULUM
Authors: BECKMAN MATTHEW D. , DELMAS ROBERT C. , GARFIELD JOAN
Published: July 2021

Cognitive transfer is the ability to apply learned skills and knowledge to new applications and contexts. This investigation evaluates cognitive transfer outcomes for a tertiary-level introductory statistics course using the CATALST curriculum, which exclusively used simulation-based methods to develop foundations of statistical inference. A common assessment instrument administered at the end of each course measured learning outcomes for students. CATALST students showed evidence of both near and far transfer outcomes while scoring as high, or higher than, on the assessed learning objectives when compared with peers enrolled in similar courses that emphasized parametric inferential methods (e.g., the t-test).

AN EXPLORATION OF STUDENT ATTITUDES AND SATISFACTION IN A GAISE-INFLUENCED INTRODUCTORY STATISTICS COURSE
Authors: PAUL WARREN
Published: July 2021

We used the Survey of Attitudes Toward Statistics to (1) evaluate using pre-semester data the Students’ Attitudes Toward Statistics Model (SATS-M), and (2) test the effect on attitudes of an introductory statistics course redesigned according to the Guidelines for Assessment and Instruction in Statistics Education (GAISE) by examining the change in attitudes over the semester and, using supplementary data from an annual Student Feedback Survey, testing for a change in overall satisfaction following implementation of the redesigned course. We took an exploratory rather than confirmatory approach in both parts of this study using Bayesian networks and structural equation modelling. These results were triangulated with analysis of focus group discussions and the annual Student Feedback Survey.

SECONDARY MATHEMATICS TEACHERS’ PLANNED APPROACHES FOR TEACHING STANDARD DEVIATION
Authors: HUEY MARYANN E. , CHAMPION JOE , CASEY STEPHANIE , WASSERMAN NICHOLAS H.
Published: July 2021

Research-based guidelines for learning variation exist (e.g., Franklin et al., 2007; Garfield, delMas, & Chance, 2007), but little is known about how teachers plan to teach standard deviation, or how these plans align with recent recommendations. In this article, we survey lesson plans designed by in-service and preservice secondary mathematical teachers. We report on the accuracy, technology usage, and visual representations in the lesson plans. We consider how many elements are used, the level of conceptual development, and the mathematical nature. Findings support differences between preservice and master’s level students in education, as well as a tendency by in-service teachers to teach in alignment with prior learning experiences, despite professional development. Implications for teacher education and curricular development are offered.

COMPARING STUDENT SUCCESS AND UNDERSTANDING IN INTRODUCTORY STATISTICS UNDER CONSENSUS AND SIMULATION-BASED CURRICULA
Authors: HILDRETH LAURA A. , ROBISON-COX JIM , SCHMIDT JADE
Published: July 2021

This study examines the transferability of results from previous studies of simulation-based curriculum in introductory statistics using data from 3,500 students enrolled in an introductory statistics course at Montana State University from fall 2013 through spring 2016. During this time, four different curricula, a traditional curriculum and three simulation-based curricula, were used. Student success rates and understanding of six key statistical concepts are compared among these curricula using mixed logistic regression. Results indicate that after controlling for salient covariates, differences in student success rates are minimal while student understanding under the simulation-based curricula are similar to or better than student understanding under the traditional curriculum suggesting simulation-based curricula may help increase student understanding of several key statistical concepts.

A FRAMEWORK TO CHARACTERIZE STUDENT DIFFICULTIES IN LEARNING INFERENCE FROM A SIMULATION-BASED APPROACH
Authors: CASE CATHERINE , JACOBBE TIM
Published: July 2021

Although hypothesis testing is ubiquitous in data analysis, research suggests it is commonly misunderstood. Simulation-based inference methods have potential to make student thinking visible, thus providing a valuable lens to analyze developing conceptions about inference. This paper identifies difficulties made visible through simulation-based methods and introduces a framework to characterize the conceptions behind those difficulties. Using the framework, difficulties can be described largely in terms of two challenges. First, students struggle to coordinate the multi-level scheme, which includes the population or true underlying relationship, the distribution of a single sample, and the distribution of statistics collected from multiple samples. Second, students struggle to coordinate two perspectives: the real world where the sample data were collected, and the hypothetical perspective where the null hypothesis is assumed to be true.

JAPANESE AND THAI SENIOR HIGH SCHOOL MATHEMATICS TEACHERS’ KNOWLEDGE OF VARIABILITY
Authors: ISODA MASAMI , CHITMUN SOMCHAI , GONZALEZ ORLANDO
Published: July 2021

In this article, the conceptions of variability held by samples of Japanese and Thai senior high school mathematics teachers were identified, based on the framework proposed by Shaughnessy (2007), using a comparative survey study. From contrasting the results of the two groups, relative tendencies of insufficient statistical knowledge for variability were found in both samples, such as a tendency of Japanese teachers to overgeneralize equiprobability, whereas Thai teachers tended to overgeneralize estimation. Based on these findings, the use of well-known tasks from the research literature for this comparative study seems useful to clarify the relative tendencies and insufficiencies in teacher knowledge and  conceptions regarding variability held by both groups.

INTRODUCTORY STATISTICS: PREPARING IN-SERVICE MIDDLE-LEVEL MATHEMATICS TEACHERS FOR CLASSROOM RESEARCH
Authors: GREEN JENNIFER L. , SMITH WENDY M. , KERBY APRIL T. , BLANKENSHIP ERIN E. , SCHMID KENDRA K. , CARLSON MARY ALICE
Published: July 2021

In this study, we examined how in-service middle-level mathematics teachers used statistics in their own classroom research. Using an embedded single-case design, we analyzed a purposefully selected sample of nine teachers’ classroom research papers, identifying several themes within each phase of the statistical problem solving process to summarize how teachers 1) planned studies and collected data, 2) analyzed data, and 3) interpreted results. The results illustrate the varying ways in which teachers used statistics to make data-based decisions about their classrooms, revealing teachers’ early development in their statistical thinking and suggesting that teachers’ required knowledge of statistics is multi-faceted, requiring both a pedagogical component and statistical knowledge for the teaching profession. Such findings have important implications for how we, as teacher educators, can best meet teachers’ professional needs.

La formation doctorale face aux défis du 21e siècle : regard sur le contexte québécois
Authors: Bangali Marcelline , Guillemette Annie
Published: July 2021

La diversification de l’employabilité des diplômés constitue désormais un point crucial de la formation doctorale. Au Québec, si les orientations gouvernementales soutiennent et reconnaissent le potentiel de cette formation dans un contexte d’économie du savoir, force est de constater dans les faits un certain décalage qui questionne l’adéquation des compétences développées au doctorat face aux défis du 21e siècle. Ce questionnement implique les transformations liées à l’économie du savoir et l’émergence du modèle de la triple hélice. C’est dans ce cadre conceptuel que sera analysée la problématique abordée dans cet article à partir des résultats d’une étude réalisée auprès de titulaires de doctorat et de responsables d’organisations. Cette recherche basée sur une enquête par questionnaire souligne un écart de perceptions entre les compétences développées au doctorat et celles recherchées par les organisations sur trois points majeurs : la gestion et l’encadrement, la collaboration et le partenariat et l’adaptabilité.
Using diary writing: a narrative of radical courage
Authors: Phillips Debra , Lindsay Elaine
Published: July 2021

This article considers the use of diary entries as primary source material in autoethnographic research. It examines how the act of diary writing can reveal a trajectory

into, and away from, an experience of depression and how diary entries can provide

grounds for conjecture about possible futures and imagined self-narratives. It describes

how ‘radical courage’, as identified by Phillips, can displace suicidal ideation and

bolster a new self-narrative of an imagined future. The article highlights the value of

diaries. More than a source of raw data for research and creative writing projects, they

offer diarists a safe place to explore and create alternative and productive selfnarratives. In their unedited state, they are a first-person, present-tense record of

emotional states, showing how context and events impact upon an individual’s life.

Diary entries can reveal to the diarist and researcher alike the beginnings of a new selfnarrative that is not yet fully imagined nor articulated. The article includes selected

diary entries and reflections on depression as a lived experience to show the connection

between radical courage and a narrative of the future. This narrative form – a narrative

of the imagined future – is commended for its therapeutic potential as a cognitive

strategy to build resilience. Through writing and speaking, the story develops as it is

lived; by being lived, the story becomes embodied.
An emotional, physical and humanistic response to performed data
Authors: Crimmins Gail
Published: July 2021

How we reach, engage with, and inform/transform our research audience depends on

the medium of communication we employ. This article demonstrates that theatrically

performed narrative data can humanise an audience’s engagement and response to

research data and encourage personal change. In particular, it discusses how verbatim

theatre was used to share the stories of women casual academics in Australia, and

describes an emotional, fully embodied, and humanistic response from the audience.

The reaction of the audience, a professional gathering of scholars (Denzin 2000),

reveals that the dramatic re-presentation of narrative data can act as a voice for Others

‘yet to be voiced’ (Arnot and Reay 2007) and prompt reflection, and the possibility of

personal change. Therefore, if the communication medium we employ is integral to the

reach and impact of our research, it should be central to our research planning and

practice and not consigned to a post-research dissemination phase.

Mathematical Model for Single and Multiple Object Extraction
Authors: Shujahuddin Amna , Khan Muhammad Salim , Ali Haider
Published: July 2021

In the image processing, noise is referred to as the visual distortion. This undesirable by-product may be captured in
an image due to unpreventable assorted reasons. The interference
of natural phenomena and technical problem, such as small sensor
size, long exposure time, low ISO, shadow noise etc., can pollute
image. The presence of noise images affects image processing outputs that include segmentation. Segmentation for noisy images is
the major concern. To tackle this issue, we propose a modernistic
model that is able neutralize the negative effects of outlier using
the characteristic of kernel function by different approaches such
as linear approach and quadratic approach for global segmentation. Moreover the weight function is used for local segmentation
of noisy images. Comparing with classical models, the proposed
technique shows robust performance. In comparison with the wellknown models such as Chan-Vese (CV) model , Yongfei Wu and
Chuanjiang He (Wu-He) model and Chunming Li (Li) model we
conclude that performance of our new model is much better.

Methods.. 4th year medical students were asked to fill out a questionnaire consisting of Likert scale, to assess the training course and SBL in general. Improvement of their knowledge after taking the course was analyzed on the basis of pre- and post-test results.

Results. Eighty-two 4th year medical students responses to the 35 questions in the questionnaire were positive and the average score was 4.57 on a 5-point Likert scale. Pre- and post-test analysis proved that the course was really productive. The average points for pretest was 20 points (SD=5,39) and 29 points for pot-test (SD=4,64).

Conclusions. “Clinical skills” course has caused a high satisfaction and motivation of the students and improved their knowledge. Knowledge enhancement and skills acquisition took place in a comfortable environment.
Approaches to Learning Through Group Work: An Empirical Analysis of Student Perceptions
Authors: Healy Margaret , McCutcheon Maeve , Doran John
Published: July 2021

Group work is used to promote employability and deeper learning in accounting education. Prior research examines outcomes but there is little understanding of actual group work processes. This exploratory study revisits, builds on and expands the work of Tempone and Martin (1999), who focused on approaches to learning in a group setting and their impact on the group work process. This study is distinguished by its emphasis on students’ cumulative experiences of group work over the entirety of a programme of undergraduate study. It reports that those indicating deep approaches to learning in a group work context attach higher value to their experience, appearing more engaged. However, those indicating strategic approaches differ little from those indicating surface approaches but find the experience more challenging, completing the task without underlying belief in either the value or relevance of group work activities. In order to address students’ approach to learning, it is necessary to first address their motivation and then persuade them of the relevance of group work to accounting education. This requires a coordinated and consistent approach, involving dialogue both between lecturers within a programme and moreimportantly between lectures and students.
Relationship Banking Within the Irish SME Sector and Its Implications
Authors: O'Donohoe Sheila , Hanley Aoife , Lyons Clare
Published: July 2021

Access to and the availability of finance for small firms has received considerable attention from policy makers. Somewhat more neglected is the concept of relationship banking, which this paper examines across two Irish regions, using the dimensions of proprietary information and multiple interactions between small firms and their bank(s). Findings from the survey suggest that SMEs maintain long and exclusive banking relationships and that bank over- draft interest margins vary significantly across firm size and duration of the banking relationship and with overdraft size. Smaller firms appear to pay more for their borrowings but it is unclear whether banks are discriminating excessively against them. This ambiguity is underpinned by the different composition of finance to smaller firms, who have smaller average overdrafts.
LIQUID POLYBUTADIENE EXTENDED ESBR/SILICA WET-MASTERBATCH COMPOSITES FOR IMPROVING ABRASION RESISTANCE AND DYNAMIC PROPERTIES OF TIRE TREAD COMPOUNDS
Authors: Kim Woong , Muhammet Iz , Kim Donghyuk , Kim Il Jin , Lee Jong-Yeop , Kim Wonho
Published: July 2021

Silica wet-masterbatch (WMB) is a well-known technique for manufacturing high-content, highly dispersed silica-filled compounds. Emulsion styrene–butadiene rubber (ESBR)/silica WMB offers several advantages, including excellent silica dispersion and reduced hysteresis, as compared with conventional dry masterbatch (DMB) compound. However, because of the residual emulsifiers in ESBR latex, it can exhibit a decrease in the crosslink density and reductions in its mechanical properties. Moreover, the abrasion resistance cannot be significantly enhanced because of the tradeoff between the improvement in silica dispersion and decrease in crosslink density. Accordingly, the objective of this study was to improve the silica dispersion and abrasion resistance of ESBR/silica WMB compounds by using liquid polybutadiene rubber (LqBR) extended WMB. In detail, three types of LqBR were emulsified to LqBR emulsions, and three types of LqBR extended WMBs were produced by co-coagulating ESBR latex, silane-modified silica, and the LqBR emulsion. A thorough characterization was conducted with emphasis on the silica content, cure characteristics, mechanical properties, abrasion resistance, and dynamic viscoelastic properties. Based on the results, silane-terminated LqBR extended WMB vulcanizate showed a 58% improvement in the 300% modulus, 48% reduced DIN abrasion loss, and a 23% improvement in dynamic properties.

THE QUATERNARY CHALCOGENIDE COMPOUND Ag2FeGeSe4: A REVISION OF THEIR CRYSTAL STRUCTURE AND MAGNETIC PROPERTIES
Authors: DELGADO Gerzon E. , DELGADO-NIÑO Pilar , QUINTERO Eugenio
Published: July 2021

Background: Quaternary compounds bellowing to the I2-II-IV-VI4 system are of considerable technological interest due to their possible use in the preparation of solar cell and thermoelectric materials devices. In recent years, considerable attention has been focused on the detailed study of quaternary chalcogenide compounds related to the chalcopyrite compounds, particularly AgInSe2, which has emerged as a leading material for the preparation of photovoltaic devices due to their potential applications in solar cell technology. Aims: This work focuses on synthesis, chemical analysis, thermal study, magnetism measurement, and crystal structural characterization of the quaternary semiconductor Ag2FeGeSe4, an essential member of the family I2-II-IV-VI4. Methods: This material was synthesized by the melt and anneal technique. The chemical analysis was carried out by scanning electron microscopy (SEM) and differential thermal analysis (DTA). Magnetic susceptibility () as a function of temperature and magnetization as a function of the magnetic field were also performed, and crystal structure analysis was made employing the Rietveld method with powder X-ray diffraction data. Results and Discussion: The preparation confirms the formation of the quaternary compound with stoichiometric 2:1:1:4 according to the chemical analysis. This quaternary compound melt at 1015 K, and show an antiferromagnetic behavior with Neel temperature TN of 240 K. The Debye temperature (D) estimated for this compound was 194 K. The quaternary chalcogenide compound Ag2FeGeSe4 crystallizes in the orthorhombic space group Pmn21, Z = 4, with unit cell parameters: a = 7.6478(1) Å, b = 6.5071(1) Å, c = 6.4260(1) Å, and V = 319.79(1) Å3, in a wurtzite-stannite arrangement with a Cu2CdGeS4-type structure, which is characterized by a three-dimensional arrangement of slightly distorted AgSe4, FeSe4, and GeSe4 tetrahedra connected by corners. In this structure, each Se atom is coordinated by four cations located at the corners of a slightly distorted tetrahedron, and each cation is tetrahedrally bonded to four anions. Conclusions: The melt and anneal method remains effective for preparing compounds chalcogenides as the quaternary Ag2FeGeSe4, a new member of I2-II-IV-VI4 family of semiconductors, which crystallizes in the non-centrosymmetric space group Pmn21 with diamond-like structure. The crystal structure information of this compound allows explaining their magnetic properties, which in combination with its semiconductor properties make this material a potential aspirant for different applications, mainly in solar cells.
The Effect of the Covid-19 Pandemic on Stress Learning
Authors: Salsabila Qorri ‘Ainan , Aqinar Zachrina , Effendi Muhamad Ridwan
Published: July 2021

Learning stress or academic stress is a category of distress in which students perceive academic demands as disturbing. It can also be interpreted as pressure related to the ability to master a science. Symptoms of learning stress include physical reactions, behaviour, thought processes, and emotions. Based on various research results, the level of learning stress increases during the COVID-19 pandemic. This is considered related to the change in the face-to-face learning system to online (in the network), which raises new factors as triggers for learning stress. This research was conducted to determine how the COVID-19 pandemic affects stress in learning and find solutions to overcome feelings of stress in learning, especially solutions from an Islamic perspective. The method used by the author in this study is a qualitative method with a literature study approach with analysis of the theory of Robert J. Van Amberg about the stages of stress. The results of the study revealed that learning stress factors during the covid-19 pandemic were in the form of lack of understanding of the material, a lot of assignments, declining grades, a tiring and boring learning system, quota constraints and internet networks, individual internal factors, and social factors other. Islam views stress as a trial that every Muslim must face. Islam also provides solutions for stress, namely patience, tawakkal, and the discipline of worship. Other solutions for learning stress during the COVID-19 pandemic can also be in the form of problem-focused coping and emotional focused coping, web-based Solution-Focused Brief Counseling (SFBC), and spiritual, emotional freedom technique (SEFT).

Los resultados de los ensayos indican que la especie comienza a germinar a los 18 a 20 días y se registran diferencias estadísticamente significativas entre las zonas para el porcentaje de germinación y el período de energía. La zona de Tanumé presentó los mayores valores de germinación y el menor período de energía. Respecto al período de energía no se registró diferencias estadísticamente significativas entre las zonas de colecta. En cuanto a la variable número de semillas por kilo, la zona de Cahuil presentó un valor significativamente más alto. Es importante proseguir los estudios en vivero, en aspectos como fecha de siembra, tamaño de contenedor, efecto de micorrizas y otras variables que permitan obtener plantas de calidad en una temporada de viverización.

El objetivo de este trabajo es determinar la edad de aprovechamiento de un individuo "tipo" de algarrobo blanco (Prosopis alba) que crece en Santiago del Estero, Argentina, bajo condiciones no limitantes más allá de las asociadas a características climáticas propias de la región. Para ello se filtró variaciones debidas al clima regional y otros disturbios y se modeló la señal biológica contenida en las series de anchos de anillos con un modelo logístico de intercepto aleatorio para contemplar y entender mejor variaciones del crecimiento entre individuos de la misma especie bajo las mismas condiciones ambientales. La esperanza marginal del modelo logístico mixto fue usada para construir curvas de incremento corriente anual y medio que, superpuestas en un mismo plano temporal, permitieron identificar la edad a la cual estos crecimientos son equivalentes (edad de culminación biológica).
Trichoderma harzianum, un biocontrol y biopromotor en vivero de especies forestales
Authors: Romero Graciela , Crosara Alicia , Baraibar Lucas Amalia
Published: July 2021

El uso de fungicidas para controlar problemas sanitarios en viveros forestales presenta problemas de manejo tanto por su toxicidad como por los problemas de resistencia de los patógenos. Esto lleva a incrementar la cantidad de productos aplicados o la frecuencia de las aplicaciones sin lograr en ciertos casos el efecto de control deseado. El objetivo de este trabajo es lograr la inclusión de Trichoderma en el sistema sustrato-plantín forestal y los resultados productivos, a través de la selección de sustratos y el ajuste de los esquemas nutricionales empleados en un vivero comercial productor de plantas de pino y eucalipto.

El trabajo tuvo como objetivo determinar mezclas de residuos orgánicos regionales para la producción de plántulas en sistemas de bloques que presenten una buena unión al sistema radicular. Para la elección de las proporciones de cada compuesto orgánico se realizaron 10 mezclas utilizándose como residuos orgánicos la fibra de coco (fibras finas, largas y mixtas), corteza de eucalipto y bagazo (residuo originado en las fábricas azucareras). Los bloques probados fueron confeccionados en una estructura de acero con dimensiones de 11,5 cm de longitud y 2,3 cm de ancho. Después de la confección de los bloques, estos fueron humedecidos y evaluados en cuanto al grado de expansión, siendo, las mezclas que presentasen mayor grado de expansión las utilizadas para producción de plántulas.

Published: July 2021

Actualmente en Tierra del Fuego, Argentina, existe una demanda por abastecimiento de materia prima de productos forestales por parte de los productores en forma constante y creciente. Dicho abastecimiento corre riesgo de no poder satisfacerse, con lo que muchos de los actuales productores deberían dejar de aprovechar el bosque. Esta situación surge de un aprovechamiento desmesurado, y se respalda en el inventario forestal provincial y las estadísticas de la Dirección de Bosques. Teniendo en cuenta esta información se estima que de continuar con la misma tasa de aprovechamiento solo quedarían masas productivas, tal cual las que hoy se aprovechan, para 10 años aproximadamente. El objetivo de este trabajo es dejar asentadas las bases y condiciones, así como la necesidad, del estudio de tratamientos intermedios en masas boscosas de lenga (Nothofagus pumilio) en la Provincia de Tierra del Fuego, Argentina. Los objetivos principales que se plantearon en el ensayo son: (i) determinar la factibilidad silvicultural de realizar tratamientos intermedios en masas juveniles de lenga, y (ii) determinar la alteración de la biodiversidad provocados por el aprovechamiento de masas boscosas juveniles. Los objetivos secundarios que se plantearon son: (i) determinar el volumen de cosecha en un tratamiento de masas juveniles de lenga, y (ii) cuantificar el rendimiento para distintas escuadrías de productos.

Published: July 2021

El presente trabajo corresponde a un modelo estático que analiza el comportamiento de un árbol ante la fuerza ejercida por el viento sobre éste. Para el establecimiento del modelo se asumió una determinada variación de velocidad del viento con respecto a diferentes alturas en el árbol, y en particular para el follaje y el tronco del árbol. De esta manera se estudio la distribución de fuerzas sobre el follaje, el momento flector, y el esfuerzo de corte, estimando de esta manera la zona de más probable fractura en el árbol
