Published: July 2021

В статье рассматривается проблема усиления внимания педагогической общественности к культуре как феномену человеческого бытия. Формирование поликультурной компетенции у педагогов и студентов способствует умению работать и обучаться в условиях инокультуры. Поликультурная компетенция рассматривается как интегративное свойство личности, которое отражает его способность решать профессиональные и повседневные проблемы и задачи на основе культуроцентрированной системы ценностей. Дефиниция «поликультурность» наиболее емко передает взаимодействие принципов диалога и взаимодействия разнообразных культур. Поликультурная личность является одной из составных частей «базовой культуры личности». Формированию «человека культуры», поликультурной личности способствует, прежде всего, определенная культурно-образовательная среда.

THEORETICAL FOUNDATIONS OF HUMAN RESOURCE MANAGEMENT IN TERMS OF INNOVATIVE DEVELOPMENT
Authors: MUNASSIPOVA M , YDYRYS S
Published: July 2021

The problems of managing the labor market and the employment of the population are given considerable attention by scientists, economists, philosophers, and sociologists. Despite the versatility of research, the problems of human resource management and improving organizational and economic management mechanisms remain insufficiently developed. Only at the regional level of management can we find effective ways to solve the most acute problems of building highquality labor potential and rational use of labor resources by developing various programs and coordinating the activities of the relevant services.

The main discrepancy between the education system and the labor market comes from the lack of forecasting methods in the workforce and imperfections of the mechanisms of social partnership. This is due to the insufficient funding of educational institutions and lack of job security for graduates. In addition, the low level of education of the economically active population of the region, the insufficiently developed training system for innovative industries, the undeveloped employment system for graduates contributing to the imbalance in the labor market, i.e. with a general quantitative prevalence of labor supply over demand, the most important sectors of the economy were not provided with the required amount of qualified specialists.

The purpose of this study is to substantiate the theoretical and methodological aspects of human resources management and labor potential, to develop proposals and recommendations for improving its organizational and economic mechanism.

An experimental study on production of high strength non-shrink grout containing fly ash
Authors: Dang Thuy Chi
Published: July 2021

Cement-based grouts are widely used thanks to its outstanding features such as high workability, non-separation, non-bleeding, easy to fulfill small gaps with complex shapes. This paper descrcibes the first phase of a series of laboratory experiments that examined the ability of production of self - levelling mortar at the University of Transport and Communications. The Portland cement-based grout incorporated superplasticizer, fly ash, fine aggregate, water along with expansion agent to match as closed as possible the given high strength non-shrink grout. The experimental study focused on the performance of non-shrink grouts regarding the flowability, expansion and bleeding, strengths and drying shrinkage of the test grout mixtures. The high range water reducer (HRWR) at dosage of 1% by weight of cement was used as a flowability modifying chemical admixture to prevent water segregation and leads to an increase in compressive strength. The parameter tests consist of water-cement ratios, and fixed dosages of superplasticizer and expansive agent. To examine the flowability of grout mortars, the flow cone test was applied. The flow cone test result indicated that there were three proportional of grouts that can meet the requirement of fluidity. The compressive strength of specimens was tested according to ASTM C349-14. It was concluded that the compositions of grouts at a water-cement ratio of from 0.29 to 0.33 have compressive strengths greater than 60 MPa. The tested specimens using the expansive agent with the dosage recommended by the manufacturer meet the non-shrinkage requirement of a grout. The experimental results have demonstrated the ability of production of high strength non-shrink grouts.

Thu hồi năng lượng dư thừa trên lưới tiếp xúc trả về lưới trung áp là một trong các biện pháp hiệu quả thu hồi năng lượng tái sinh trong quá trình hãm, xuống dốc của các đoàn tàu trong quá trình vận hành. Để đạt được hiệu quả thu hồi lớn nhất, bên cạnh chế độ điều khiển thì vị trí và dung lượng các bộ nghịch lưu đóng vai trò rất quan trọng. Bài báo này trình bày một phương pháp xác định vị trí tối ưu và dung lượng của các bộ nghịch lưu trong hệ thống cung cấp điện kéo cho các tuyến đường sắt đô thị. Mục tiêu là tìm được phương án bố trí nghịch lưu để tối thiểu hóa tổng chi phí tiêu thụ điện năng và chi phí đầu tư các bộ nghịch lưu, từ đó mang lại lợi ích kinh tế lớn nhất. Phương pháp đề xuất được thực hiện trong hai giai đoạn. Giai đoạn thứ nhất áp dụng thuật toán trào lưu công suất để xác định mức năng lượng tiêu thụ và năng lượng thu hồi tại mỗi trạm điện kéo tương ứng với các trường hợp bố trí nghịch lưu trong các chế độ vận hành. Giai đoạn hai tìm kiếm vị trí và dung lượng các bộ nghịch lưu để tổng chi phí là tối thiểu. Thuật toán đề xuất được kiểm nghiệm trên một mô hình hệ thống cung cấp điện xây dựng theo số liệu tham khảo từ tuyến đường sắt Cát Linh – Hà Đông. Kết quả mô phỏng cho trường hợp vận hành 11 đoàn tàu, thời gian từ 5h đến 22h hàng ngày trong 10 năm thì chi phí khi có trang bị nghịch lưu là 252,98 tỷ so với 340,6 tỷ khi không dùng nghịch lưu. Kết quả mô phỏng cho thấy hệ thống ví dụ được tối ưu hóa và khả năng tiết kiệm năng lượng của nó là đáng chú ý.

Introduction: changes in eating habits in childhood during the COVID-19 pandemic could create predisposition to future diseases. Objectives: to explore eating habits and physical exercise in childhood during the pandemic; to estimate body satisfaction, overweight and obesity; to describe habits that influence nutritional status. Materials and methods: a survey was carried out with Google Form, available for a period of four months in 2020 and disseminated in the media. 306 surveys of girls and boys, between 6 and 12 years old, from the province of La Pampa were obtained. Results: a reduction in physical activity during the pandemic was observed in 27% of the sample group. Low consumption of fish, nuts, legumes and seeds was evident. Only 15% of those surveyed stated that they eat vegetables daily and 50% fruits and dairy products. 40% consumed juices, sodas and sugary drinks 3 to 4 times a week and 32% added salt to their meals as a daily habit. 19% of the sample group said that their diet was worsened during the pandemia. An increase in both, the hours of sleep and the hours in front of the screens, was demonstrated. The increase in participation in the preparation of home-cooked meals and family dining was highlighted as positive. In relation to the anthropometric data, the Body Mass Index indicated: 15% were overweight and 7% obese. 70% were satisfied with their weight, 26% would like to lose weight and 4% would like to increase it. Conclusions: the low frequency of consumption of fruits and vegetables could cause nutritional deficiencies. In general, the situation of confinement imposed by the health emergency, resulted in a deterioration of food quality and increasing sedentarism. The anthropometric results agree with the Argentine studies of the prevalence of overweight and obesity and in turn alarm about the situation of body discomfort.
Competencia política y desempeño de los gobiernos municipales
Authors: Velázquez Guadarrama César
Published: July 2021

Este artículo estudia la relación entre la competencia política y el desempeño de los gobiernos municipales en México con datos de 1990 a 2015. Los resultados sugieren que a mayor competencia política se observa una mayor cobertura de agua potable y de drenaje por parte de la población y un mayor ingreso per cápita. Un posible mecanismo por el cual se observan estos resultados es que también se advierte que a mayor competencia política se presenta un mayor gasto en inversión pública y un menor gasto corriente como proporción del gasto total. Sin embargo, este último resultado no se encontró para municipios con población mayor a 15 mil habitantes. En las estimaciones se controló por la posible endogeneidad entre las variables de desempeño y finanzas públicas y la competencia política. Es necesario continuar investigando el papel de los gobiernos estatales y municipales en el desarrollo del país.
Genetic diversity in Coffea canephora genotypes for leaf nutrient concentration
Authors: Alves da Silva Cleidson , Azevedo Santos Eileen , Pio Viana Alexandre , Machado Dias Jairo Rafael , Partelli Fábio Luiz
Published: July 2021

This study analyzed the genetic diversity in Coffea canephora genotypes by univariate and multivariate statistical analysis, based on concentrations of macro- and micronutrients in coffee leaves in the stages of pre-flowering and grain filling. The experiment was arranged in randomized blocks with three replications, in a 42x2 factorial design, in which factor one represented the evaluated genotypes and factor two the periods of leaf sampling, i.e., pre-flowering and grain filling. The data of leaf nutrient concentrations were subjected to analysis of variance by the F test (p <0.01), and genetic parameters were estimated. For the study of genetic diversity, the genotypes were grouped by the hierarchical unweighted pair-group method using arithmetic averages (UPGMA). The relative importance of a trait to predict genetic diversity was also studied. There is genetic divergence for leaf nutrient concentration in C. canephora genotypes. With a maximum limit of 60% of dissimilarity between genotypes, four groups were also formed by UPGMA. For the 42 evaluated genotypes, leaf S concentration was the most important trait for genetic diversity; this genotypic variability should be investigated to enhance the efficiency of nutritional diagnosis.

Highlights

There is genetic variability for leaf nutrient concentration in Coffea canephora

The leaf concentration of nutrients in the phenological stage of pre-anthesis is different from the leaf concentration of nutrients in the coffee bean filling period.

Leaf concentration of sulfur was the characteristic that contributed most to the genetic diversity among the 42 genotypes, followed by the concentration of copper, boron and magnesium.

Genotypic variability for leaf nutrient concentration should be considered for better nutritional management.
Forage production and leaf proportion of lucerne in subtropical environments: cultivar, cutting frequency and canopy effects
Authors: Berone Germán , Bertrám Nicolás , Di Nucci Elena
Published: July 2021

In subtropical and humid environments the ‘winter-active’ cultivars of lucerne usually produce more forage with lower leaf proportion (i.e. leaf to stem ratio) than the ‘winter-dormant’ ones. Present research analyze (i) if differences in forage production changes with cutting frequency, and (ii) if differences in leaf proportion are intrinsic (i.e. ‘cultivar differences’) or are due to variations in plant morphology (i.e. ‘aerial biomass and canopy height’). In two subtropical locations a factorial experiment including three alfalfa cultivars (FD4= ‘winter-dormant’, FD6=‘semi-dormant’, FD9=‘winter-active’) and three cutting frequencies (‘high’, ‘intermediate’ and ‘low’) was established. As the cutting frequency decrease (i.e. from ‘high’ to ‘low’) the more winter-active cultivars were more productive than the more winter-dormant ones (FD9>FD6>FD4) due mainly to a higher stem production. However, differences between cultivars disappear (FD9=FD6=FD4) as the cutting frequency increases (i.e. from ‘low’ to ‘high’ cutting frequency). Compared at similar canopy height, differences between cultivars in leaf proportion were practically irrelevant. We confirm that (i) in subtropical and humid environments, the differences in forage production between cultivars contrasting in their winter activity depend of the cutting frequency, and that (ii) the leaf proportion depends mainly of plant morphology, especially canopy height’, being irrelevant the cultivar and the environment.

Highlights

This paper shows that (i) differences in forage production between cultivars of lucerne depend on the cutting frequency, and that (ii) leaf proportion is governed by plant morphology, especially canopy height.

Forage production was similar between cultivars at high cutting frequency but at low cutting frequency winter-active and semi-dormant cultivars (FD6 and FD9) produce more forage than winter dormant (FD4) ones.

Lucerne cultivars showing the same leaf proportion when they were compared at similar canopy height suggesting that leaf proportion is not an intrinsic trait

Changes in leaf proportion were better explained by changes in canopy height than by changes in thermal time.
Environmental factors affecting germination of Mimosa ephedroides (Fabaceae), an endemic shrub from Monte Desert, Argentina
Authors: Dágata Sofia Leonor , Fernández María Emilia , Passera Carlos Bernardo
Published: July 2021

Mimosa ephedroides is an endemic shrub from western Argentina. The knowledge of the germination response of this species to different environmental factors contribute to its efficient use in ecological restoration projects. This study aimed to examine aspects of seed quality, seed dormancy, and the effect of temperature, water and saline stress on the germination of this species. Also, the effect of seed storage time on the viability and the percentage of germinated seeds were evaluated. Experiments were carried out in controlled growth chambers. Germination percentage and mean germination time were calculated. It was found that this species has non-dormant seeds. Concerning abiotic factors, the optimum temperature for germination ranged from 20 to 30 ºC, it presented high germination percentages even at moderate and severe water stress (-1.12 MPa), and the germination percentages decreased with increasing salinity levels from 300 mM NaCl. In short periods (up to 36 months), seed storage at room temperature (18ºC) was adequate, not affecting the viability and the germination power of the seeds. These results constitute a contribution to the knowledge of the autecological aspects of this endemic species, support its incorporation for restoration projects, and aid to an efficient use of native seeds for direct seeding or seedling production.

Highlights

Mimosa ephedroides seeds are non- dormant, show high viability and rapid germination (>24 h).

This shrub is able to germinate in a wide range of temperatures and under moderate and severe water stress.

High salinity levels (<300 Mm NaCl) negatively affected seed germination.

Seed storage for short periods (<5 years) at room temperature (18ºC) did not affect seed viability and germination.
Preliminary use of a fulvic acid, as a strategy to improve water use in saline soils
Authors: Kremer Cristián , Díaz José , Seguel Oscar , Tapia Yasna
Published: July 2021

An evaluation of a fulvic acid (FA) was made in a Loam soil, by selecting the best dose to achieve salt displacement under a drip emitter. In trial 1, PVC columns were filled with a loam soil and irrigated with a KCl solution of electrical conductivity (EC) of 12.5 dS m-1. Once the soil solution EC reached the value of the KCl solution, FA doses of 0, 2.1, 5.3 and 10.5 kg ha-1 were applied. The bulk electric conductivity and soil chemical properties were evaluated after 6 irrigation cycles. In trial 2, the same soil salinized with the KCl solution was placed in 0.8 m3 containers. Two irrigations treatments were performed: a control and the best FA dose from trial 1. The displacement of the salt bulb created from irrigation with a dropper in the soil profile was characterized. In trial 1, the dose of 5.3 kg ha-1 reached the lowest EC after the third irrigation. In trial 2, the selected dose reduced EC until 3.75 dS m-1 at 0.3 m depth at the third irrigation, saving 246 L of water compared to control. Additionally, the salinity bulbs were more horizontally extended in the FA treatment.
Highlights:

Application of FA (5.3 kg ha -1) reduced the water use by 50% compared to leaching carried out exclusively with water.
The use of Fulvic acid showed to be an alternative to consider in the recovery of saline soils under drip irrigation when irrigation water is scarce.
Little or not residual effect was found after the use of Fulvic acid.

This study aimed to evaluate the reuse of treated domestic sewage in biquinho pepper (Capsicum chinense L.) cultivation under different irrigation regimes. The experiment was carried out in a greenhouse, in a randomised block design with a 3 x 4 factorial scheme, with four replications. Forty-eight pepper plants were subjected to three treated domestic sewage concentrations (0, 50, and 100%) and four irrigation depths (75, 100, 125, and 150% of the crop evapotranspiration - ETc). Data for ETc estimation were obtained from an automatic meteorological station, which was installed in the greenhouse. The results showed that irrigation depths corresponding to 125 and 150% of the ETc at a concentration of 100% treated domestic sewage resulted in higher plants. Moreover, longer fruits were obtained when plants were subjected to 100% ETc at 100% treated domestic sewage. The studied irrigation depths influenced pepper fruit total weight and yield. No treated domestic sewage concentrations significantly influenced the variables analysed. Treated domestic sewage reuse can constitute an alternative for quality water saving and for chemical fertilisation of biquinho pepper crop.
Highlights:

The growing of beak pepper with domestic sewage treated can bring benefits in terms of providing nutrients to the crops;
Adequate levels of water replacement with domestic sewage treated may promote good crop development.
The use of treated domestic sewage can be an alternative to reduce the use of better quality water and chemical fertilization in the growing of beak pepper.
Reduction of environmental impact may be possible with the replacement of chemical fertilizer by domestic sewage treated in the growing of beak pepper.
Arthropods of the Limarí River basin (Coquimbo Region, Chile): taxonomic composition in agricultural ecosystems
Authors: Pizarro-Araya Jaime , Alfaro Fermín M. , Muñoz-Rivera Rodrigo A. , Barriga-Tuñon Juan E. , Letelier Luis
Published: July 2021

The Limarí valley, located in the Coquimbo Region of Chile, is an important agricultural area that is immersed in the transverse valleys of the Norte Chico. In recent decades, the continuous expansion of agriculture towards dry land zones has favored the migration and establishment of potential pests, such as arthropods, that may affect crops or be zoonotic agents. Based on the limited knowledge we have about the arthropod group present in the Limarí basin, our objective is to describe the taxonomic composition of the assemblage of economically important arthropods inhabiting this basin of the semiarid region of Chile. After reviewing historical data, specimen collections, and the specialized literature, a total of 414 arthropod species were recorded. Of the total number of species recorded, 92.5% were insects, the most diverse taxon, with 11 orders. Arachnids, in turn, were represented only by Acari with 31 species. The most widely represented orders of insects were Coleoptera, Hemiptera, and Lepidoptera. Within Coleoptera the most species-rich families were, in decreasing order of importance, Curculionidae, Coccinellidae, Cerambycidae, Scarabaeidae, Chrysomelidae (Bruchinae), Ptinidae, and Bostrichidae; within Hemiptera these were Aphididae, Diaspididae, Coccidae, Pseudococcidae, Pentatomidae and Rhopalidae; and within Lepidoptera they were Noctuidae and Tortricidae. We hope this study serves as a starting point for identifying the most diverse arthropod groups and developing pest monitoring and control programs.
Highlights:

A large percentage of phytophagous species, mainly belonging to Acari, Lepidoptera, Hemiptera and Coleoptera, were registered in the Limarí basin.
Some families of agricultural importance (Aleyrodidae, Aphididae, Coccidae, Diaspididae, Margarodidae, Pseudococcidae), were observed in large agricultural crops in the basin (e.g., vines, oranges, mandarins, lemon trees, avocado trees, walnuts, olive trees, vegetable crops).
A smaller fraction corresponded to the group of predators and parasitoids, mainly represented by Coleoptera (Coccinellidae), Neuroptera (Chrysopidae) and Hymenoptera (Braconidae, Encyrtidae, Ichneumonidae, Platygastridae, Signiphoridae).
The richness and spatial records of arthropods were mostly concentrated between the city of Ovalle and the estuary of Punitaqui - the areas with most intense agricultural activity in the Limarí basin.

Published: July 2021

We evaluated the effects of urea addition on gas and effluent losses, fermentation profile, microbial populations, aerobic stability and chemical composition of corn silages. A completely randomised design with five levels of urea (0, 0.5, 1.0, 1.5, and 2.0% based on dry matter) and five replicates was used. A decreasing linear effect of urea levels on effluent losses in corn silages was observed. In parallel, an increasing linear effect of urea levels on pH, increasing from 3.49 to 4.12 in silages without urea in relation to silages with the maximum urea level, was also observed. Urea addition improved the aerobic stability of the silages, with 62 h for the silages without urea and from 90 to >96 h for the silages with urea. Based on the results of the principal components, two groups (I and II) could be distinguished. The most discriminating variables in group I were dry matter (-0.9), pH (-1.2) and lactic acid bacteria (-0.9), while in group II, effluent losses (1.0), ethanol (1.0), acetic acid (0.8) and gas losses (0.8) were most important. The use of urea at inclusion levels of around 2% in corn silage reduced gas losses, improved the nutritive value and promote the aerobic stability of silages.

Highlights:

The addition of urea in the corn silages increased the pH values from 3.49 (control) to 4.12 (2% of urea DM).

The use of urea improved chemical composition of corn silages.

Published: July 2021

Today the digital data that world produces is unseen and spectacular. The data from social media, e-commerce and Internet of things generate approximately 2.5 quintillion of bytes per day. This amount is equals 100 million Blu-ray discs or almost 30,000 GB per second. Till today data is growing and will continue to grow in future. In the field of Health care industry, big data has opened new ways to acquire intelligence and data analysis. Collected records from patient, hospital, doctors, medical treatment is known as health care big data. Big data by machine learning are assembled and evaluates the large amount of data in health care. Analytic process and business intelligence (BI) is growing up day by day, as it acquires knowledge and makes right decision. As it is vast and complex growing data, it is very difficult to store. The tradition method of handling big data is incapable to manage and process big data. Hence to resolve this difficulty, some machine learning tools are applied on large amount of data using big data analytics framework. Researchers have proposed some machine learning approaches to improve the accuracy of analytics. Each technique is applied, and their results are compared. And this concluded that we get accurate result from one machine learning approach are called as Ensemble Learning. The final result observed that ensemble learning can obtain high accuracy. In this paper we shall study about various methods to process big data for machine learning and its statistic approaches. Further we study various tools for storing of big data, its advantages, and disadvantages in the field of health care industry.

Motivational dispositions behind how learners approach, interpret, and respond to challenging goals can serve as beneficial foundations to conflict management training and implementation. There is a dearth of research connecting the constructs of goal orientation and conflict management and this study does so, for the first time in an agricultural leadership context. Using The Conflict Management Scale and The Work Domain Goal Orientation Instrument, 80 members of a LEAD21 agricultural leadership development cohort exhibited a 15.2% increase in conflict management capacity. Learning goal orientation was predictive of conflict management capacity prior to the start of LEAD21. Both learning goal orientation and performance goal orientation-prove were found to have predictive qualities after LEAD21 conflict management training. In addition to a discussion on future research directions, educators, as well as learners, are encouraged to incorporate goal orientation into curriculum development and planning for the enhancement of learning environments.

Published: July 2021

Experiential learning is a foundational element to agriscience education. The purpose of this study was to examine the effects of reflection type and abstraction order on students’ scientific reasoning skills when teaching experientially. Three major conclusions can be drawn from this study: (a) reflection type and abstraction order are independent of one another; (b) reflection-on-action, regardless of abstraction order, is more effective when developing students’ scientific reasoning skills; and (c) preabstraction is more effective when developing students’ scientific reasoning skills regardless of reflection type. It is recommended that future studies be replicated with a larger sample population, provide a longer duration of treatment, and consider individual learning styles as they pertain to reflection, abstraction, and other dependent variables not examined in this study. Regarding recommendations for practice, it is recommended that professional development opportunities exist for in-service teachers. The developers of professional development opportunities should focus on how to better develop students’ scientific reasoning skills through experiential learning, reflection as a teaching strategy, and designing learning experiences. Finally, the results of this study should be shared with pre-service teachers in teaching methods and curriculum design courses to allow preservice teachers to make informed decisions when designing learning experiences.

Published: July 2021

Sustaining human capital in the agricultural industry is critical to the United States’ ability to maintain preeminence in the global economy. This goal has become a greater challenge due to declining participation in agricultural academic programs, particularly at 1890 institutions. Although the anticipated outcome of the 1965 “merger” of the New Farmers of America (NFA) and the Future Farmers of America (FFA) was to achieve synergy in this effort, the outcome was counterproductive in terms of the participation by people of color. This qualitative study utilized interviews, guided by 7 questions, to examine 22 African American teachers’ perceptions of the impact of the merger. Participants taught agriculture in public schools in one southern state and/or were members and/or advisors in the NFA. Participants perceived that the merger was a “takeover” that led to a critical absence of participation and leadership development among African American youths. Participants agreed that the merger had a drastic, negative impact on the number of African American agriculture teachers produced and the number of individuals in the pipeline for agriculture-related careers, thus, a negative impact on building the industry’s human capital. Findings from this study should induce innovative strategies to overcome the shortage of African Americans pursuing agriculture-related careers.
The Masks We Wear: A Quantitative Analysis of Motivational Factors of School Based Agriculture Education Teachers During a Pandemic
Authors: Clemmons Chrisopher A. , McKibben Jason , Lindner James
Published: July 2021

Prior to the COVID-19 pandemic, school-based agriculture education (SBAE) was framed within a traditional approach to teaching and learning; teachers and students shared classrooms, met learning objectives, and promoted their local FFA programs. This study address the degrees of personal and professional motivation experienced by secondary agriscience teachers transition to remote/distance education instruction during the COVID-19 global pandemic. The theoretical framework for this study was structured within expectancy value theory (Atkinson, 1957) and bound by Weiner’s attribution theory (1972). Atkinson (1957) postulated that individual decisions dictate a person’s role in behaviors associated with a defined task. Three research objectives guided this investigation to more clearly understand teachers’ perceptions of personal and professional motivation: identify the characteristics of Alabama SBAE teachers during the pandemic, articulate how COVID-19 affected SBAE teacher’s personal dispositions toward teaching agriscience education, and understand SBAE teachers’ professional motivation during COVID-19. The questionnaire invitation was sent to 115 (n = 115) middle/secondary school agriscience education teachers in Alabama with 64 (n = 64) respondents attempting the questionnaire. Respondents indicated positive motivation in addressing their professional duties as a classroom teacher even as they lack the traditional classroom or lab. Teachers were motivated to make positive changes in their program with regards to FFA and SAE but are less than positive about their ability to make those changes in the online learning modality. This is consistent with existing understandings of online learning and the embrace of novel experiences.

Authors: Thiel Brooke L. , Marx Adam A.
Published: July 2021

The purpose of this study was to identify the factors, attitudes, and beliefs that led secondary schoolbased agricultural education (SBAE) teachers to adopt agriscience research Supervised Agricultural Experiences (SAEs) into their programs. Nine current SBAE teachers from North Dakota participated in semi-structured interviews regarding their experiences with agriscience research SAEs. The interviews were subjected to two rounds of coding and were collapsed into themes during a third round of analysis. A myriad of experiences, beliefs, and factors contributed to teachers’ decisions to adopt agriscience research SAEs into their programs. However, the most salient reasons were compatibility with the overall goals of the school district, a commitment to whole student development, teacher ability and support, multitasking behavior, extensive teacher planning and student support, and positive student buy-in. Though the unique experiences of the participants are not generalizable beyond the present study, we offer recommendations for teacher educators, state staff, and teacher leaders regarding the further adoption and integration of agriscience research SAEs into SBAE programs nationwide.

Published: July 2021

A priority of agricultural teacher education programs is to develop technically competent, prepared school-based agricultural education (SBAE) teachers. SBAE teachers should be knowledgeable in various agricultural subject matter, such as agricultural mechanics. Using Roberts and Ball’s (2009) Content-based Model for Teaching Agriculture as the conceptual framework for our study, we used a three-round Delphi technique to identify the agricultural mechanics knowledge and skills SBAE teachers in Arkansas, Louisiana, Oklahoma, and Texas need to successfully teach agricultural mechanics courses. Spread across all four states, a panel of 47 SBAE teachers with expertise in agricultural mechanics contributed data for our study. Thirty-five teachers participated in all three rounds. After all three rounds were completed, 71 technical agricultural mechanics knowledge and skill items (e.g., circular saw use, computer numerical control [CNC] systems use, etc.) and 49 agricultural mechanics “teacher skill” / laboratory management knowledge and skill items (e.g., budget management, developing a student traffic control system, etc.) were identified. We recommend various efforts to help expand teachers’ competence in these items should be undertaken within these states, including: (1) establishing and expanding partnerships with agricultural industry stakeholders to provide professional development opportunities for SBAE teachers, (2) realigning agricultural teacher education courses and experiences to better reflect teachers’ agricultural mechanics knowledge and skill needs, and (3) facilitating opportunities for teachers to develop competence in agricultural mechanics through SBAE teacher-led training. To help provide systematic, consistent examination of teacher competence needs in agricultural mechanics, replication of our study should occur at regular intervals.

Published: July 2021

Many universities and professional associations recognize excellence in teaching with awards; however, research findings on the impact of an award on teaching identity are mixed. The objective of this study was to qualify the impact of receiving a National or Regional United States Department of Agriculture Teaching, Extension, and Research Award (TERA) on teaching identity. Secondarily, this study explored how well award-winning teachers’ self-identities and behaviors corresponded with recognized characteristics of excellent teaching. A phenomenological approach utilizing semistructured interviews and researcher reflexivity was used to gather information from 12 TERA recipients. Findings indicate that faculty members recognized for excellence in teaching demonstrate known characteristics of effective teachers, seek guidance from the Scholarship of Teaching and Learning, and feel that teaching continues to be less valued than research in their institutional cultures. Results suggest that departmental and college level administrators can foster subcultures that promote teaching excellence through access to professional development opportunities, support for peer mentoring and evaluation, and revised promotion and tenure policies that recognize teaching effectiveness as a productivity metric.
