En gran parte de las empresas de galvanoplastia debido a la demanda y el tiempo de los procesos, es muy complicado realizar un estudio a nivel piloto para controlar las variables que determinan la cantidad y calidad de los depósitos. Por lo tanto, en este trabajo se presenta un estudio para determinar las condiciones de corriente y potencial, así como evaluar algunos tipos de agitación para controlar la calidad de los depósitos, utilizando soluciones electrolíticas de la industria. Se utilizó una celda electrolítica típica con capacidad de 72 L conectada a una fuente de poder, como ánodos se usaron placas de latón y como cátodo se utilizó una lámina de acero inoxidable 304, utilizando un multímetro para registrar la corriente y el potencial durante el electrodepósito. La agitación de la solución electrolítica se controló de tres formas: flujo de aire, propela y utilizando propela con un equipo sonotrodo. Los resultados mostraron que el codepósito de Cu-Zn (latonado) ocurre en un intervalo de corriente entre 0.35 a 0.37 A y un voltaje de -0.35 0 -0.42 V, para evitar la evolución de hidrógeno o que únicamente se deposite cobre. También se determinó que el tipo de agitación donde se controla mejor el depósito fue con la propela y el equipo sonotrodo juntos. Mientras que, de las tres formas diferentes de agitación, la que mejor dio resultado fue la agitación con el sonotrodo junto con la propela, que evita una pasivación de la superficie de los ánodos por la posible formación de óxidos, obteniendo además un flujo más controlado de los iones del ánodo hacia el cátodo.

En la localidad de Huajomulco en el municipio de Tulancingo en el estado de Hidalgo se encuentra una cavidad en el subsuelo denominada “El Quebracho”, la cual geológicamente tiene rasgos de tubo de lava o también llamada tubo-lava, generadas debido a derrames de lava viscosa de tipo basálticas. La Tomografía de Resistividad Eléctrica (TRE) es una herramienta mediante la cual se logra caracterizar el subsuelo a través de varias mediciones de potencial eléctrico a lo largo del terreno, teniendo como respuesta los diferentes valores de resistividad respectivos de cada uno de los materiales, en este caso se utilizó para detectar y caracterizar la estructura. Se obtuvieron 5 perfiles de resistividad 2D a lo largo de los cuales se logró identificar el tubo-lava, así como unidades geoeléctricas, morfología, litología y los diversos materiales del subsuelo.

De acuerdo con los resultados de resistividad obtenidos con las TRE se logró obtener resultados favorables para la caracterización 2D del tubo-lava, comprobando la versatilidad que tiene el método al momento de aplicarse. Esta metodología puede ser empleada en posteriores estudios para determinar el contexto geológico del subsuelo y evaluar los riesgos geológicos en la localidad debido a la existencia de un posible sistema de Tubo-lavas

Authors: ŞIK Emre , DEMİRTAŞ Hasan
Published: October 2022

Okul yöneticilerinin ders denetimine ilişkin öğretmen görüşlerinin tespit edilmesi amacıyla yapılan araştırma, 2020 yılı Kasım ayında Malatya ilinde bulunan Milli Eğitim Bakanlığına bağlı okullarda görev yapmakta olan 20 öğretmen ile yüz yüze görüşme tekniği ile yürütülmüştür. Araştırmada veri toplamak için yarı yapılandırılmış görüşme formu kullanılmıştır. Görüşme formunda araştırmaya katılan öğretmenlerin kişisel bilgilerinin tespit edilmesi amacıyla hazırlanmış 7 soru ve öğretmenlerin okul müdürlerinin ders denetimi ile ilgili görüşlerini tespit etmek amacıyla sorulmuş 7 açık uçlu soru bulunmaktadır. Araştırmadan elde edilen veriler üzerinde betimsel ve içerik analizleri yapılmış, veriler kodlara ve kodlar da temalara ayrılmıştır.
Araştırmada okul müdürlerinin ders içeriği konusunda tam bilgili olmamaları, denetim konusunda yeterli eğitimi almamış olmaları, ders denetiminin formalite olarak kalması ve taraflı denetim gibi durumların denetimin verimsiz hale gelmesine sebep olacağı bulunmuştur. Araştırma sonucunda, ders denetimi yapan okul müdürlerinin yaptıkları denetimin şeklinin ve niteliğinin, denetimin olumlu katkısının olması bakımından önemli olduğu, ders denetiminin okul müdürleri tarafından yapılmasının aslında verimli olmadığı fakat denetimsizliktense ders denetiminin okul müdürleri tarafından yapılmasının olumlu olacağı, ders denetiminin önceden belirlenmiş çerçevede yapılması gerektiği sonuçlarına ulaşılmıştır. Araştırmada ayrıca, okul müdürlerinin ders denetimi yapmalarının okuldaki mesleki yozlaşmanın önüne geçeceği, denetim sırasında okul müdürlerinin tarafsız olmaları gerektiği, denetim yapılmamasındansa okul müdürlerinin ders denetimi yapmalarının uygun olabileceği belirlenmiştir.
Bifidobacterium animalis subsp. lactis A12 prevents obesityassociated dyslipidemia by modulating gut microbiota-derived short-chain fatty acid production and energy metabolism in high-fat diet-fed mice

Published: October 2022

Background: Bifidobacterium lactis A12 (B. lactis A12) has been shown to have the potential to prevent obesity. However, the mechanisms by which it affects the control of energy metabolism have not been fully elucidated.

Objective: The present work aimed to clarify the mechanisms by that B. lactis A12 has an effect on the management of energy metabolism.

Design: Three- to five-week-old male C57BL/6J mice were randomly divided into five groups, 15 mice for each group. Low-fat diet (LFD) group and high-fat diet (HFD) group were fed with phosphate-buffered saline (PBS) on a daily basis. Cell-free supernatant (CFS), A12, and B. lactis BB12 (BB12) groups were fed with daily probiotics for 10 weeks (1 × 109 CFU of every strain).

Results: The results showed that A12 effectively alleviated relieved weight gain and dyslipidemia, inhibited liver adipose accumulation, and improved leptin resistance in HFD-fed mice (p < 0.05). The anti-obesity effects of B. lactis A12 were closely related to the assembly of short-chain fatty acids (SCFAs), SCFA-downstream receptors, and glucagon-like peptide-1 (GLP-1) secretion. Additionally, high-throughput sequencing of the 16S rRNA showed that B. lactis A12 supplementation reversed HFD-induced gut microbiota dysbiosis, which was possible related to the augmented abundance of SCFA-producing bacterium and a minimized ratio of Bacteroidetes to Firmicutes in mice.

Conclusions: B. lactis A12 prevents obesity in some pathways, including the downregulation of sterol regulatory element binding protein-1 mRNA levels in the liver, modulation of the structure of gut microbiota in a gut microbiota-dependent manner, and the upregulation of the SCFA-producing bacteria-related G protein-coupled receptor 43 pathway.

THE SMART SPECIALIZATION APPROACH THROUGH THE PRISM OF THE KEY PROVISIONS OF THE THEORY OF FREE TRADE: CONCLUSIONS FOR UKRAINE
Authors: Pidorycheva Iryna , Omelyanenko Vitaliy
Published: October 2022

The purpose of the article is to analyze the approach of smart specialization through the prism of key provisions of D. Ricardo's theory of comparative advantage, to identify its limitations for industrial weak countries and on this basis to identify key guidelines for the development of smart specialization strategies in Ukraine in view of the challenges of the postwar era. Materials and methods. The study is based on theoretical works of Ukrainian and foreign scientists on the problems of implementing the approach of smart-specialization in the practice of regional development. The work was carried out using the methods of systematization and generalization, analysis and synthesis, comparative analysis, and systematic approach. Results. The theoretical basis of the approach of "smart specialization" is revealed, the synthesis of economic schools, theories and concepts underlying this approach is defined. The insufficient theoretical development of its main provisions, which is negatively reflected in practice, especially in less economically developed countries and regions, was substantiated. It is concluded that the reasons for this lie, in particular, in the limitations of the Ricardian theory, on the provisions of which the smart specialization approach is based. It is emphasized that the Ricardian theory does not take into account the technological factor, which considers the technological base of the country as a constant, which does not give industrial weak countries an opportunity to change the raw material nature of their economy to a fundamentally new - innovative one. The historical retrospective traces the strategy of development of economically powerful countries in achieving their international competitive advantages, which is diametrically opposed to Ricardian theory. On the basis of this the key guidelines for the development of strategies of reasonable specialization in Ukraine in the post-war period of its reconstruction in order to prevent the preservation of the raw material nature of the national economy and its secondary position in the world are outlined. Conclusion. It is proved that post-war reconstruction of Ukraine should be aimed at radical changes in the structure of the economy, the transition from the agrarian-raw type to industrial-innovative type on the basis of creating a modern high-tech industry in the conditions of unfolding in the world of a new technological revolution.

Este artigo discute a leitura numa turma de 2º ano de uma escola pública analisando dois eventos de alfabetização: um observado numa aula de Língua Portuguesa e outro numa aula de Ciências Humanas e da Natureza. A perspectiva teórico-metodológica busca uma convergência entre “certa compreensão ético-crítico-política da educação” elaborada por Paulo Freire e uma perspectiva antropológica da escrita, com base nos Novos Estudos do Letramento (NEL), além de se assentar numa concepção de linguagem da Teoria da Enunciação de Bakhtin e seu Círculo. Na produção dos dados foram mobilizados diferentes instrumentos, tais como a observação participante, com notas em caderno de campo e entrevistas. As análises dos eventos indicaram que na aula de português, o texto era tratado superficialmente,  por meio da leitura silenciosa e interpretação escrita individual, com ênfase na decifração, distanciando-se da produção de sentidos; nas aulas de Ciências Humanas e da Natureza foi  possível observar uma perspectiva mais dialógica, com leitura coletiva e discussão de ideias. Nós argumentamos que o trabalho com os textos e a leitura no processo de alfabetização, sobretudo nas aulas de língua materna, pode ser mais fecundo quando se presta ao diálogo e à construção e ampliação de sentidos pelas crianças.
Corpo como Representação

Published: October 2022

Este artigo investigou valores e representações do corpo da mulher na cidade de Bragança (PA) e vilas por ela administradas entre 1916 e 1940. O seu eixo central consistiu em entender a relevância do corpo outorgada pelas vítimas, réus, juízes, peritos, promotores, delegados e testemunhas no lugar e no tempo em questão. À vista disso, de forma mais específica, as preocupações a seguir concentraram-se na concepção de que o corpo era apresentado e representado à sociedade de forma diversificada e ampla, por exemplo, aquando dos crimes sexuais, ele foi fundamentado por meio de certos significados (o da desonra, o da imoralidade), porém, aquando do exame pericial, o sentido concentra-se no de vê-lo “restaurado” à ofendida, à sua família e à coletividade. Assim sendo, as pilastras a sustentar essas reflexões foram 13 exames de corpo de delito (presentes em autos de defloramento, estupro e rapto-defloramento), legislação e obras coevas.
Enhanced Technology for Logistics Courier Delivery Using RFID Label to Minimize Processing Time
Authors: Novitasari Nia , Anwar Nashirudin
Published: October 2022

Courier services have become a sector that has experienced a growth spurt during the Covid-19 pandemic. The soaring growth of courier services is due to e-commerce in Indonesia. Increased people's digital activities show this during the pandemic, including online or online shopping. Data from the Indonesian Ministry of Finance shows that purchase transactions via e-commerce increased 18.1 percent to 98.3 million, with a total transaction value of 9.9 percent to Rp20.7 trillion. Fast and efficient delivery and pick-up of goods is the core operation of courier services. The biggest challenge for courier service providers is how to compete with other companies that offer the same type of service. Service users are increasingly demanding the security and reliability of delivery services so that they can meet the expectations of service users. The expectations of service users used as targets for company achievement are (1) reliability (on time, accuracy, integrity), (2) convenience (collecting units, delivery coverage, operating hours), (3) services, and (4) cost. Based on the activities in courier services, the potential for errors or inefficiencies in processing time is in the pre-delivery activities. In the pre-delivery activity is also the initial activity used to input the data base, collect goods, distribute goods and so on. This research proposes that RFID Label technology can overcome errors and increase process time efficiency in shipping goods on courier services, especially in pre-delivery and delivery activities.

Published: October 2022

One of the problems of SME is the low motivation to collaborate; the lack of research on exploring the motivation to collaborate is an issue that needs to be focused on solving.Â Objectives. This research aims to explore the level and type of motivation that influences SME's interest in collaborating to provide new insights for SME managers to apply appropriate treatment in developing collaborative activities. This study analyses six octalysis core drives that affect user interest in the use of SME collaboration gamification applications involving 293 SME respondents in the East Java Province. The research method is descriptive and quantitative, using Smart PLS, with a path analysis and analysis model. This study formulates six hypotheses to determine the effect of six core drives on using the collaborative gamification system. The results showed that the four constructs had aÂ p-value less than 0.05 and aÂ T-Statistic value greater than 1.96, while the other two constructs produced the opposite value. This finding reveals that four core drives (Epic Meaning, Development, Social Influence, and Avoidance) affect user interest in using collaborative gamification applications. In contrast, two core drives (Ownership and Unpredictable) do not affect it. The implication of this study is a recommendation for developers of collaboration-gamification systems to consider the results of this hypothesis, especially the role of core-drive catalysis as a reference in revising or developing collaborative gamification systems. Future work could apply the TAM model to analyze the technology acceptance rate of this system.
Exploration of The Impact of Kernel Size for YOLOv5-based Object Detection on Quadcopter
Authors: Rahmania Rissa , Corputty Felix , Wibowo Suryo Adhi , Saputra Dany Eka , Istiqomah Annisa
Published: October 2022

Drones or quadcopters have been widely used in various fields based on deep learning, especially object detection. However, drone vision characteristics such as occlusion and small objects are still being explored for performance in terms of accuracy and speed detection. The YOLO architecture is very commonly used for cases requiring high-speed detection. To overcome the limitations of drone vision, in this paper, we explore the size of the YOLOv5s backbone kernel in the shallowest convolutional layer to achieve better performance. The kernel is a filter that has a main role in the feature map, and it defines the size of the convolution matrix, and the resulting features in the shallowest convolutional layer are more representative of the case of object detection and recognition. The techniques can be divided into three major categories: (1) data preprocessing, which involves augmentation and normalization of the data, (2) kernel size exploration in the shallowest convolutional layer of the YOLOv5s, and (3) model implementation in the real environment using the quadcopter. The dataset consisted of four classes representing dragon fruit, snake fruit, banana, and pineapple, with a total of 8000 data. Exploration results with kernel size give promising results. Kernel sizes 5 and 7 give an mAP of 0.988. Through these results, modification of the kernel size provides an opportunity for more in-depth investigations, such as with the epoch parameter, padding scheme, and other optimization techniques.

Surabaya is the second largest city in Indonesia with very fast population growth. Currently, 30 percent of the people in Surabaya are low-income people. In the context of accelerating poverty alleviation, the Surabaya City Government stipulates Surabaya Mayor Regulation Number 58 of 2019, concerning procedures for collecting, processing, utilizing, and reporting data for low-income communities. The theory used is policy implementation according to George Edward III. The factors consist of communication, resources, disposition, and the structure of the bureaucracy. This research is qualitative research with a descriptive approach. The results of this study are limited to the process of collecting and processing MBR data that were found not to be right on target for underprivileged communities in Surabaya. There are obstacles in its implementation, namely in the process of clarity of information and also staff in data collection for MBR. With recommendations 1) The government should often evaluate MBR data every month so that it knows if there are residents whose economic status has improved, 2) Provide clear information to the public, 3) Increase the number of staff for surveys to MBR locations and must have integrity in order to be able to dispel data on residents who are not categorized as MBR.

The aim of this study was to examine the relationship between participation and academic emphasis in schools based on the views of school principals. The research group consisted of 828 Turkish school principals who participated in the 2018 Teaching and Learning International Survey. Within the scope of the research, the School Leadership Scale was used to determine the approaches of school principals to the participation of teachers, the Participation Among Stakeholders Scale was utilized to determine their views of stakeholder participation, and the Academic Pressure Scale was applied to determine the academic emphasis of the schools. In order to determine the participation level, the School Leadership Scale and Participation Among Stakeholders Scale were combined in path analysis. In the analysis of the data, t-tests, ANOVA, and LSD tests were used as post hoc tests, and Pearson correlation analysis and path analysis were performed. As a result of the research, it was determined that school principals’ views were close to high levels regarding teacher and stakeholder participation and they were at high levels regarding academic emphasis. Significant positive correlations were observed between teacher participation, stakeholder participation, and academic emphasis, and school principals’ views on participation were found to be significant predictors of academic emphasis.
Un modelo de análisis medial y multimodal de musicales traducidos: el caso de Notre Dame de París (2001)
Authors: Soto Bueno Daniel Ricardo
Published: October 2022

En este trabajo se pretende contribuir al desarrollo de los estudios descriptivos de traducción en el ámbito de la traducción de musicales escénicos en España a través de un estudio exploratorio. Desde un enfoque medial y multimodal, se propone un modelo de análisis de musicales traducidos que se ilustra con un estudio del contexto y del paratexto de Notre Dame de París (2001), así como del medio y de la multimodalidad en una de sus canciones («La canción de la zíngara», cotejada con su texto origen). El análisis del contexto, del paratexto y del texto seleccionado viene a reforzar dos ideas recurrentes en la literatura: la fidelidad contextual‑funcional del texto meta con respecto al texto origen y la tendencia a importar producciones atractivas para el gran público y accesibles desde el punto de vista del contexto interpretativo meta.
Hibridación de géneros y traducción: La alumna de Alessia Gazzola
Authors: Morillas Esther
Published: October 2022

El presente artículo tiene como objetivo analizar la traducción al castellano de la novela de Alessia Gazzola L’allieva (La alumna, traducción de Patricia Orts). La característica principal de esta obra es la hibridación de géneros, concretamente el policíaco-detectivesco y la chick lit. Partiendo de la idea de que cada género literario crea una serie de expectativas en el público lector, y de que quien traduce deberá dominar los recursos y mecanismos que permiten identificar a un género como tal, en las páginas que siguen se dará cuenta de los puntos de unión y divergencia en L’allieva entre la chick lit y la novela detectivesco-policíaca, y de cómo se ha abordado la traducción de sus particularidades dando prioridad a los elementos propios de esta última.
Traducción y apropiación literaria: sobre la labor traductora de Anna Gavalda
Authors: Marín Hernández David
Published: October 2022

Cuando el escritor estadounidense John Williams publicó Stoner en 1965, la novela pasó prácticamente desapercibida. Sin embargo, en la actualidad tanto la crítica como el gran público coinciden en valorarla como un clásico de la narrativa norteamericana. En este trabajo se estudiarán las razones de la mala recepción inicial que Stoner sufrió en su país, así como el papel decisivo para su recuperación que desempeñó la traducción francesa de la novela, realizada por la novelista Anna Gavalda en 2011. Una comparación entre el relato de Williams y la versión de Gavalda demuestra que la autora francesa modificó profundamente el estilo de la obra original y la reescribió como si fuera uno de sus best sellers románticos. Esta traducción nos permitirá reflexionar sobre el concepto de apropiación como modalidad de reescritura.
Traducción de elementos eucarísticos al náhuatl: activación modernizadora e intercultural
Authors: Villegas Salas Lilia Irlanda , Figueroa Saavedra Miguel
Published: October 2022

El objetivo del estudio es analizar la dimensión intercultural y sociolingüística del proceso de traducción español-náhuatl litúrgico del Masewalxochitlasohkamatilis - Ordinario de la Misa Náhuatl realizado por el Equipo Nacional de Traductores Nahuas de la Conferencia del Episcopado Mexicano y consensuado con la comunidad nahuahablante. A través de una perspectiva teológica intercultural y un análisis procesual, contextual, documental y contrastivo-retrotraductor, se evidencia esta traducción especializada como inculturadora, optando preferentemente por estrategias cognitivas y compensatorias con el uso de la paráfrasis, del equivalente acuñado y la creación discursiva. Sociolingüísticamente, este acto de traducción constituye, por una parte, un fenómeno de activación y modernización lingüística y, por la otra, un ejercicio de esencialismo estratégico e identidad teológica intercultural que desembocan en una acción lingüística emancipatoria descolonial.
Un marcador conversacional alemán y su traducción: posición y funciones de also en el diálogo ficticio
Authors: Robles Sabater Ferran
Published: October 2022

Este trabajo analiza el uso de also en los diálogos de la novela Kleiner Mann – was nun?, de Hans Fallada, y su traducción al español. Mediante la aplicación de criterios estructurales y funcionales, se explica el modo en que esta partícula aparece representada en la obra y cómo su empleo ayuda a generar la ilusión de autenticidad que define la oralidad ficticia, pues su habitual posición periférica y sus funciones —vinculadas a la interactividad, el mantenimiento de la coherencia discursiva y la estructuración de la conversación— contrastan con sus usos prototípicos en la escritura. Por otra parte, se muestra cómo la elección de un equivalente de traducción en un momento concreto del diálogo se puede explicar en gran medida en consideración de las distintas maneras en que also contribuye a la construcción del discurso.
Control of Organic Impurities in Semisynthetic Antibiotics

Published: October 2022

In 2012, the European Medicines Agency (EMA) adopted a guideline, which divided all antibiotics into groups according to the manufacturing process and established acceptance criteria for organic impurities for each of the groups.

The aim of the study was to justify the requirements and methodological approaches to setting the limits for organic impurities in semisynthetic antibiotics.

Materials and methods: the authors analysed the requirements established by the leading world pharmacopoeias and the State Pharmacopoeia of the Russian Federation regarding the control of organic impurities in semisynthetic antibiotics, using the example of four semisynthetic antibiotics: doxycyline hyclate, clarithromycin, meropenem, and ceftriaxone. The study used the methods of comparative analysis and content analysis.

Results: the study demonstrated that the organic impurity profiles of the analysed active substances and the corresponding finished medicinal products often differ significantly across the leading pharmacopoeias, either qualitatively or quantitatively. The Russian, European, and United States pharmacopoeias provide for the use of impurity reference standards in the test procedures for the determination of impurities in active substances of the semisynthetic antibiotics in question, whereas the Japanese Pharmacopoeia allows the use of non-compendial reference substances in the assessment of the chromatographic system separation power.

Conclusions: the ability of a pharmacopoeial text to cover a variety of medicinal products coming to the Russian market from different countries has become a vital issue. This includes covering the impurity determination procedures, reference standards, and limits used, because general-purpose methods and limits do not always allow for correct assessment of impurity profiles in substances produced by different manufacturing processes. The current USP practice is to include various impurity control procedures in monographs on medicinal products, and the limits may also vary. This approach may be applied in the State Pharmacopoeia of the Russian Federation as well.
Assessment of cold resistance in Momordica charantia l. accessions according to pollen germination at low temperatures in vitro
Authors: Fotev Yu. V.
Published: October 2022

Background. Bitter melon (Momordica charantia L.) is a vegetable and medicinal crop new for Russia. Its high heat demand is the main factor limiting the possibilities of its cultivation in a temperate continental climate. Evaluation and selection of more cold-resistant accessions is required for breeding new cultivars and expanding production. Previously obtained data attest to a possibility of assessing cold hardiness in the mature male gametophyte phase in vitro.

Materials and methods. Eight bitter melon accessions, including parent forms, F  hybrids and cv. ‘Gosha’, were grown in the unheated film greenhouse of the Central Siberian Botanical Garden, Novosibirsk (54°49’ N, 83°06’ E) for evaluation and selection for cold resistance. The ratio of pollen germination in vitro on a 15% polyethylene glycol solution with a molecular weight of 6000 (PEG 6000) with the addition of boric acid (0.006%) at a temperature of 10°C for 24 h to the same indicator at 25°C / 3 h (in %) was used as a criterion of cold resistance.

Results. The cultivar ‘Gosha’, the accession Okinawa green from Japan, and the F1 hybrid (Feng Guang × Okinawa green) had the highest cold resistance, with the values of 59.7; 53.8 and 48.2%, respectively. The inheritance of cold resistance in F , assessed by the pollen germination index, depending on the crossing combination, changed from intermediate in two hybrids [F1 Feng Guang × Gosha) and F1 Feng Guang × Okinawa green)] to overdominant (positive heterosis) in the hybrid F1 (Feng Guang × Okinawa white).

Published: October 2022

Общая анестезия (наркоз) — состояние, характеризующееся обратимым угнетением ЦНС, которое проявляется выключением сознания, подавлением чувствительности (в первую очередь болевой) и вегетативных рефлексов, снижением тонуса скелетных мышц. С момента внедрения в клиническую практику были достигнуты значительные успехи как в применении общих анестетиков, так и в изучении механизмов их действия. В представленной лекции рассмотрены как первые абстрактные теории общей анестезии, так и идентифицированные молекулярные мишени препаратов, а также и их роль в реализации основных эффектов общих анестетиков.
Reflections on technology, teaching, learning, and professional development: Findings from a teacher survey in Tanzania
Authors:   EdTech Hub, UK, Koomar Saalim
Published: October 2022

This paper presents findings from a survey of 774 government school teachers across Tanzania over the period 2020–2021. The aims were to capture teachers’ recent experiences concerning (1) access and use of technology; (2) any student learning losses observed, and teachers’ recommendations to address lost learning; and (3) experiences and needs concerning teacher professional development (TPD). Key findings were (1) forty percent of teachers reported that their school lacked access to any form of technological device, with almost half stating they never used digital technologies for teaching and learning purposes. (2) Almost half of the teachers perceived that girls’ learning suffered more than boys, and more than 60% of teachers believed learners from the financially poorest households suffered the greatest learning losses. (3) Teachers in Tanzania engaged in very little TPD and wanted increased support. The key differences across teacher groups were further examined by demographic factors, with notable differences apparent between urban and rural teachers, teachers with different levels of experience and different qualification levels. Recommendations are presented to stakeholders across the education ecosystem, including policymakers, school leaders, TPD designers, teachers, and researchers. The findings inform a national technology-mediated TPD programme in Tanzania.
