Published: June 2022

En 1963 se inició un programa de investigación destinado a determinar las posibilidades de establecer una explotación pecuaria, utilizando como base el más importante recurso vegetal de la zona desértica del país, el tamarugo (Prosopis tamarugo).

En los años siguientes se realizó investigación relativa a aspectos de producción animal, buscando las razas ovinas y caprinas de mejor adaptación a esas condiciones y se iniciaron estudios tendientes a determinar las prácticas más adecuadas para la producción de plantas y forestación.

Junto a investigaciones sobre la fisiología de la especie, también se realizaron estudios con el propósito de conocer el potencial productivo de este nuevo recurso.

El presente trabajo sirve como balance de la labor realizada en la Pampa del Tamarugal, buscando reunir y analizar las actividades llevadas a cabo en materia de investigación, sobre aquellos temas que tengan relación directa con las especies del género Prosopis que crecen en la zona.

Es así como se ha reunido información sobre aspectos generales tales como el clima, el suelo y la vegetación y temas más específicos relacionados con la fisiología, la productividad, el mejoramiento y el manejo del recurso.

Además una parte importante de este trabajo ha sido la evaluación del recurso forestal, mediante la determinación de la superficie cubierta y la clasificación de los bosques de acuerdo a su estado.
Regulatory approaches to preventing organised crime among outlaw motorcycle gangs
Authors: Dowling Christopher , Morgan Anthony
Published: June 2022

Regulatory approaches to organised crime aim to minimise exploitation of the legitimate economy by offenders. Unlike criminal justice approaches, regulatory approaches prioritise prevention over enforcement. This study explores the impact of a regulatory approach to organised crime in Queensland which restricted outlaw motorcycle gang (OMCG) members from working in certain industries. We exploit a delay in the implementation of these occupational restrictions after a wider suite of measures commenced, using interrupted time series analysis to analyse changes in organised crime related harm by OMCG members. Results suggest that the introduction of occupational restrictions was followed by a gradual reduction in organised crime related harm by OMCG members (3% to 4% per month). While the reduction is small, it supports the view that regulatory measures are a promising strategy for reducing organised crime.
Eltérő itemműködés vizsgálata az országos kompetenciamérésben halmozottan hátrányos helyzetű diákok körében többdimenziós IRT modellek segítségével
Authors: Kispál Sára , Gergely Bence
Published: June 2022

Kutatásunk célja, a halmozottan hátrányos helyzetű diákok Országos kompetenciamérésen nyújtott teljesítményének feltérképezése, melynek alapját Kispál, Gergely, T. Kárász és Takács (2020, kézirat) kutatásának eredményei adták. A halmozottan hátrányos helyzetű diákok minden évben részt vesznek az Országos kompetenciamérésen, ám teljesítményük elmarad az átlagtól. Fő célkitűzéseink közé tartozik megvizsgálni, hogy itemek szintjén megjelenik-e különbség a halmozottan hátrányos helyzetű diákok feladatmegoldásában, vannak-e olyan feladatok melyek kifejezetten nehezebbek vagy könnyebbek a számukra, illetve tudják-e kompenzálni az egyik kompetenciaterületen való hiányosságaikat a másikkal? Két statisztikai modell vizsgálata során(továbbiakban M2, M4 modell) megállapíthattuk, hogy mindkét esetben fennáll differenciált itemműködés, ugyanakkor az M4-es modell mutatja láthatóan, hogy a teszt információs görbéje a szövegértés dimenzióról sokkal több információt szolgáltat, mint a matematika dimenzióról. Ugyanakkor jelentősen elmarad az információ-tartalom maximuma a nem halmozottan hátrányos helyzetű csoporttól. Item-jellemzők és tartalmi kódolás vizsgálata esetén csak a tényismeret és egyszerű műveletek területen figyelhető meg szignifikánsan nagyobb esély a differenciált itemműködés megjelenésére. Összegezve elmondható, hogy a halmozottan hátrányos helyzetű diákok a matematika feladatok megoldásánál sokkal inkább a szövegértési kompetenciájukat veszik igénybe. Abban az esetben, ha a feladat nem kíván több matematika tudást, mint szövegértést, nem okoz differenciált itemműködést, míg ellenkező esetben igen. A szerzők a tanulmány alapjául szolgáló kutatást az Országos kompetenciamérés kutatócsoport 20642B800 témaszámú, a Károli Gáspár Református Egyetem Bölcsészet-és Társadalomtudományi Kara által finanszírozott pályázat keretében végezték.

Az országos kompetenciamérés eredményeinek statisztika feldolgozása a szövegértés és az idegen nyelv kedveltségének összefüggésében
Authors: Guld Andrea Mária , Csanádi Katalin
Published: June 2022

Ebben a tanulmányban azt vizsgáljuk, hogy vajon az anyanyelv tanulása után az idegen nyelv tanulása, az idegen nyelvtantárgy szeretete és az iskola tanterve milyen befolyást gyakorolhat az anyanyelvi szövegértésre. A szakirodalom-kutatásunk limitált eredménnyel járt, az általunk vizsgált témakörben három kisebb kutatást találtunk és foglaltunk össze, amelyek a matematika szövegértés fejlesztését vizsgálták a matematika tantárgy révénilletve az idegen nyelv tanulásának kapcsolatát (tanterv) a szövegértéssel. Az idegen nyelv tanulása általi agyi változásokról egy rövid összefoglalót írtunk. A statisztikai elemzéshez két reprezentatív, nagymintás adatállományt, a 2017-es Országos Kompetenciamérésben résztvevő 6. és 8. osztályos tanulók eredményeit használtuk fel: 6. osztályos tanulók száma 91.599, illetve a 8. osztályos tanulók száma 87.990. Mivel idegen nyelvi osztályzat nem szerepel az OKM-ben, ezért azadottiskolahelyitantervét vettük figyelembe, tekintettel arra, hogy abban a normál tanterv mellett szerepel nemzetiségi és kéttannyelvű általános iskola, ami az idegen nyelv magasabb szintű (például emelt óraszám, vagy adott tantárgyak idegen nyelven való oktatása) tanítását feltételezi., De az iskolai tanterv-adatállományban szereplő emelt szintű („tagozatos”)tantervű iskolák adatait is tartalmazza az elemzés(ennél pontosabb specifikációt az adatbekérés nem tartalmaz), mivel ez –habár azt nem tudjuk mely tantárgyattanuljáka diákok emelt szinten-finomhangolhatja az analízist a szövegértés tekintetében. Emellett az idegen nyelv tantárgy szeretetét is a vizsgálat tárgyává tettük, szintén az idegen nyelv hiányzó osztályzata miatt, feltételezve, hogy az idegen nyelv tantárgyat szeretők jobb osztályzattal rendelkezhetnek. Az elemzésben a 2017-es Országos Kompetenciaelemzés 6., illetve 8. osztályos tanulóinak standard szövegértés pontszámát (O zpsc), az iskola helyi tantervét [normál, nemzetiségi, kéttannyelvű, emelt színtű (TA01002)], illetve az idegen nyelv tantárgy szeretetét (TA05511), mindezek kapcsolatát vizsgáltuk a megadott adatállomány alapján. A 6. osztályos tanulók száma az adatbázis alapján: 91.599 fő. A tanuló neme a központi adatbázis alapján: 44.546 lány (48, 63 %) és 47.053 fiú (51,37 %). Tanterv alapján érvényes adat 75.950 főnél volt, hiányzó adat 15.649. Az idegen nyelv szeretetének érvényes adata 75.887, hiányzó adat 15.712. A 8. osztályos tanulók száma az adatbázis alapján: 87.990 fő. A tanuló neme a központi adatbázis alapján: 43.470 lány (49, 4 %) és 44.520 fiú (50,6 %). Tanterv alapján érvényes adat 69.671 főnél volt, hiányzó adat 18.319. Az idegen nyelv tantárgy szeretetének érvényes adata 69.255, hiányzó adat18.735. Az eredmények: az elemzés eredménye azt mutatja, hogy mind az iskola tanterve és a szövegértés, mind az idegennyelv tantárgyának szereteteés a szövegértés között kimutatható kapcsolat.
A tanulmányi eredményességgel összefüggésbe hozható tényezők az országos kompetenciamérés adatai alapján

A cikkben a 2017-es Országos Kompetenciamérésben résztvevő 6., 8. és 10.évfolyamos tanulók adatai alapján vizsgálom a teljesítményt a családiháttér, a motiváció és az óvodában töltött évek számának tükrében. A családi háttéren belül a családiháttér-indexet, a testvérek számát, valamint a szülői bevonódottságot emelem ki. Modellemet az IBM SPSS 25 statisztikai program lineáris regressziós eljárásával teszteltem. Az eredmények értelmében elmondható, hogy a fentnevezettváltozók közül a családi háttérnek van a legnagyobb jelentősége a tanuló teljesítményének tekintetében. Emellett az eredmények alapján elmondható, hogy a testvérek számának növekedése negatívösszefüggésben vana tanulmányi eredménnyel. A szülői bevonódottság tekintetében a három vizsgált kérdés eltérő összefüggésben van a tanuló tanulmányi eredményével. A gyermekkel történtek otthoni megbeszélése pozitív, míg a házifeladatban való segédkezés, valamint a gyermek olvásmányélményeinek való megbeszélése negatív összefüggést mutat a tanulmányi eredménnyel. Az óvodában töltött évek száma változó esetében elmondható, hogy a változó egységnyi növekedése pozitív összefüggést mutat a tanulmányi eredményre, ám ez azösszefüggéskisebb mértékű, mint a családiháttér esetében. A családi háttér változón belül a családi-háttérindex a legmeghatározóbb. A motivációnak egészena10.véfolyamig nem látjuk kiemelkedését, ám 10. évfolyam esetén a motiváció jelentősége standardizált esetben elsődlegessé válik.

A colonização do mundo rural e a emergência de novos atores
Authors: Brandenburg Alfio
Published: June 2022

Este texto tem por objetivo problematizar a noção de mundo rural e analisar as condições de emergência de novos atores. A partir da ideia de colonização do rural, os personagens que reagem ao processo de racionalização unilateral da vida social e biológica são definidos como novos atores, na medida em que reconstroem relações com o ambiente social e natural. A ação de novos atores inscreve-se no contexto de um campo de disputa de linguagens ecossociais e de distintas ruralidades, construindo-se uma racionalidade que se contrapõe ao domínio da racionalidade instrumental: a racionalidade ambiental ou ecológica.

Gear analysis of freshwater Macrobrachium species catch at Igbedi Creek for regulation recommendation in Bayelsa State, Nigeria
Authors: BINAEBI EDUBAMO DAVIDSON  , DEEKAE SUANU N
Published: June 2022

Gears are tools for fishing without which the fisher cannot gain access to the fisheries resource in Nigeria. The gears at riparian communities of Ogoubiri, Toru-Ebeni, Amassoma and Otuan along Igbedi Creek, Bayelsa, Nigeria were analyzed to evaluate the effect on the shrimp catch at the Creek, for regulation recommendation, by measuring the gears utilized and the length of the shrimps caught from each gear. This research revealed that there were three species of Palaemonidae: Macrobrachium vollenhovenii, M. macrobrachion and M. felicinum which were harvested with Hand-push nets, Non-return valve traps and Non-return net traps. The traps were generally small in size and few. A total of 156 gears, with catch ranging from 0 to 1309. The mean length and width for each gear range from 36.75±4.16cm and 25.64±2.88 cm to 38.73±3.73 cm and 26.99±2.67 cm for G1, 131.58±6.73 cm and 19.17±2.15 cm to 127.54±4.06 cm and 18.39±1.55 cm for G2, 107.58±1.70 cm and 20.27±0.58 cm to 108.01±1.65 cm and 20.35±0.03 cm for G3 and 91.44±0.00 cm and 60.96±0.00 cm to 91.64±0.52 cm and 61.21±0.98 cm for G4. The entrance hole ranging from 2.49±0.38 cm to 61.40±0.78 cm in all four locations and species catch ranging from 2.2 cm to 9.8 cm for M. macrobrachion, 2.0 cm to 12.8 cm for M. vollenhovenii and 2,5 cm to 8.4 cm for M. felicinum at the stations. The gears allow the escape of shrimps less than 1.9 cm. This implies that growth overfishing can be averted but recruitment overfishing is inevitable if the fishers continue in the free access conditions and increase catch capacity therefore, this study recommend gear size and seasonal catch regulation.

Authors: Yulia Dewi Zwista , Artilia Ira , Padilah Silvia , Farras Muhammad
Published: June 2022

Alginate is widely used in dentistry as an impression material. Manipulation of commercial alginate impression materials with the addition of Trisodium Phosphate (TSP). It is known to prolong the setting time of alginate by reacting it first with calcium sulfate. Dental students in their first grade sometimes have difficulty manipulating alginate so they need a longer manipulation time. There is no alginate product with a longer setting time in the market. From this study, we added 2% TSP to add setting time for dental education. The purpose of this study to characterize was to determine the compressive strength of alginate molding materials that have been added with TSP to commercial alginate products with factory standards. Setting time, compressive strength, EDS, and SEM was used as a characterization. This research was true experimental research. It was conducted using normal type printed materials with one of the brands available in the market. The results of this study were then analyzed using paired T-test, the compressive strength of alginate without and without TSP 2% was a significant difference. The addition of 2% TSP affected the compressive strength of the alginate impression material.

Authors: Ayukarningsih Yoke , Amalia Jihan , Nurfahfah Gita
Published: June 2022

Thalassemia is an autosomal recessive single gene disorder due to an imbalance in the production of globin chains, namely α-globin and β-globin chains, which until now the case is increasing with manifestations of severe anemia and can have an impact on nutritional status. Malnutrition is one of the effects of thalassemia due to rapid erythrocyte turnover. The purpose of this paper is to discuss and provide information regarding the definition, epidemiology, classification, pathogenesis, diagnosis, complications, management, and nutritional status to minimize growth disorders in thalassemia patients. This research is a literature study, which is a type of research that collects, manages, uses, and reviews research data sourced from scientific research journals, previous research manuscripts, and textbooks. The results of the literature review are a factor of good nutritional status in thalassemia patients can be affected by various factors, one of which is increased energy expenditure which can offset good intake and consumption patterns. One of the assessments of nutritional status in thalassemia patients is the Upper Arm Circumference (UAC) because it can be used in organomegaly patients. Many factors can affect the nutritional status of children, especially in children with thalassemia.
EFFECTIVENESS OF CHEWING GUM AND TOOTHPASTE OF XYLITOL ON THE PLAQUE INDEX IN ADOLESCENT GROUP.

Published: June 2022

Periodontal disease and caries are part of dental and oral health problems. The main cause of periodontal disease and caries is plaque. Dental plaque can be controlled with a combination of chemicals and mechanics treatment. The growth of dental plaque can be inhibited by using chemicals, namely xylitol which can be used in the form of chewing gum or toothpaste. Xylitol is a natural carbohydrate sweetener that cannot be fermented by bacteria in the oral cavity. Xylitol can accumulate Streptococcus mutans intracellularly and make Streptococcus mutans expends energy to break down accumulated xylitol without producing unfavorable energy. This research was conducted as literature study and analyzed the findings obtained. This literature review used six pieces of literature about xylitol chewing gum and two pieces of literature about xylitol toothpaste. Data analysis used Paired Samples T-Test of plaque index. The results showed that there was a statistically significant result (p<0,05) of the plaque index before and after using xylitol chewing gum. On the other hand, there was no significant result (p>0,05) on the plaque index before and after using xylitol toothpaste. The decreased plaque index was established in both of the xylitol types, but not meaningful when used in toothpaste.

Signs and symptoms of temporomandibular disorders/TMD often occur in edentulous patients. Etiology and clinical symptoms are different so the diagnosis is different. The diagnosis of TMD can be determined using Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) Axis I (clinical examination) and Axis 2 (psychological examination). The purpose of this study was to obtain a description of temporomandibular joint disorders in edentulous patients at the Dental Hospital of Padjadjaran University based on DC/TMD Axis I. This research was a descriptive study with a survey technique. The sample size was 32 patients that were collected by consecutive sampling. Temporomandibular disorders in edentulous patients were obtained by filling out symptom questionnaires and clinical examination based on DC/TMD Axis I, then grouped using the DC/TMD Axis I algorithm. The results showed that from 32 edentulous patients who visited the Dental Hospital of Padjadjaran University, there were 23 subjects diagnosed with temporomandibular disorders, with disc displacement with reduction (40.63%) as a major diagnosis, followed by local myalgia and myofascial pain in 2 subjects (6.25%) each, and arthralgia in 1 subject (3.12%). Subjects who had more than one diagnosis as many as 5 people (15.62%). According to the result of the study, most of the edentulous patients visiting the Dental Hospital of Padjadjaran University were diagnosed with temporomandibular disorders, and disc displacement with reduction was the most common diagnosis.
A Priori Justification in Nietzsche
Authors: Remhof Justin
Published: June 2022

This paper argues there are crucial points in Nietzsche's texts where he offers a priori epistemic justification for views he believes are correct, contrasting with the dominant view that Nietzsche's philosophical naturalism is incompatible with a priori justification. My aim is to develop Nietzsche's brand of a priori justification, show that he employs this account of justification in the texts, and suggest how it might be compatible with naturalism.
Il vicus di Bedriacum: note di archeologia del paesaggio
Authors: Bursich Daniele
Published: June 2022

Bedriacum era adagiato nell’intersezione tra vie d'acqua e terrestri, su un dosso che permetteva un guado sicuro sul fiume Ollius. Durante il corso delle indagini archeologiche effettuate nell’ultimo secolo, sono state condotte parallelamente anche analisi non invasive del territorio, che hanno portato a una definizione geologica di dettaglio, una visione d’insieme data dalle fotografie aeree, dall’analisi del sottosuolo tramite prospezioni geofisiche e il costante raffronto con le fonti storiografiche. In vista della nuova stagione d’indagini che si sta prospettando per il vicus, si propone una rapida revisione dell’edito e dei dati d’archivio relativi alle indagini non invasive condotte a più riprese, per una prima lettura del paesaggio archeologico di Calvatone-Bedriacum.
Le raffigurazioni di felini in ambra nella Penisola italiana
Authors: Negroni Catacchio Nuccia , Gallo Veronica
Published: June 2022

Si prendono qui in esame le ambre figurate preromane che rappresentano felini. Tra i rinvenimenti della Penisola italiana si contano ad oggi 33 esemplari, ma molti altri sono conservati in musei stranieri, senza indicazione del luogo di ritrovamento; coprono un arco cronologico compreso tra la metà del VII e il IV secolo a.C. e provengono da Etruria padana, Piceno, regioni meridionali (attuali Puglia, Basilicata e Campania) e area etrusco-laziale. Al di fuori della Penisola, alcune ambre sono state portate alla luce in Serbia, Israele e Siria. I manufatti italici fungevano per lo più da pendagli e, talvolta, rivestivano un arco di fibula. Dal punto di vista iconografico, si tratta soprattutto di protomi, di felini in posizione accovacciata, di scene con più animali e di altri unica. Lo studio stilistico delle ambre figurate in forma di felini ci permette di ricostruire infine parte delle vie di scambio attive durante l’età del ferro, delineando, ad esempio, la circolazione dei medesimi modelli lungo la sponda adriatica italiana nei secoli VI e V a.C.

The purpose of this study is to determine the leadership style of school principals in dealing with the modern world from the perspective of the sociology of education, the benefits of this research are beneficial as a reference for principal school leadership to prepare agents of educational change in the face of today's modern world. Modern times all definitely need challenges in the world of education, education must be able to adapt and carry out transformations to keep up with the times, the research used is qualitative research with a descriptive approach, researchers explore data through interviews, with school principals and teachers as well as community members who live in the environment. State Elementary School 007 Sangatta Utara, East Kutai Regency, and from the documentation, the researcher then analyzed the data following the miles style, then by reducing the data after the interview so that less relevant information could be filtered out to near perfection after data reduction then drew conclusions. The findings from the researchers show that there is still a lack of principals in following technological developments, plus the facilities are still inadequate, ideally in schools having 25 computers or laptops and schools do not yet have a computer lab to support school programs so that the program does not run optimally. The principal is very important and must master technology to make it easier for education personnel to control.
Differences of Search Engine Digital Footprints Between Podiatrists and Foot and Ankle Orthopaedic Surgeons: A Need to Join the Digital Era
Authors: Chiang Benjamin J. , Malik Zeeshan , Laubach Logan , Minchu Prem , Gu Alex , Chodos Marc D.
Published: June 2022

Background:

Search engines generate lists of the most relevant websites using a keyword or phrase query and are integral in guiding consumer preferences. Digital information is important in the field of medicine, influencing what patients learn about their conditions and who they choose as providers. When two types of healthcare providers, such as podiatry and foot and ankle orthopaedic surgeons (FAOSs), share an overlapping consumer market, whichever group has a larger digital footprint receives increased digital engagement.

Methods:

The Google search engine was used to query nine common foot and ankle–associated terms using a “search term + zip code” format for 150 zip codes divided into urban, suburban, and rural population densities. The first 10 results of each search were classified into one of five categories. Site content was classified as podiatry-oriented, other MD/DO-oriented, or FAOS-oriented. Separately, a ratio between podiatrists and FAOSs was calculated for each population density group. Data were then normalized using this ratio and reanalyzed with the Wilcoxon signed-rank test with significance at P < 0.05.

Results:

Of 13,500 total search results, 4,992 (36.9%) were podiatry-oriented, 2,109 (15.6%) were other MD/DO-oriented, and 436 (3.2%) were FAOS-oriented. All geographic areas featured a higher number of podiatry than FAOS-oriented sites. FAOSs have more results per provider in urban areas (P < 0.001), although podiatrists had more in suburban and rural areas (P < 0.001, P < 0.001). Podiatrists have greater digital engagement in descriptive search terms. “Ankle replacement” has greater FAOS engagement in all three geographic areas.

Discussion:

Foot and ankle–related Internet search terms results are overwhelmingly composed of podiatry-oriented sites. Per provider, regional differences are demonstrated, with FAOS having more sites in urban areas only. FAOS scope-of-practice terms such as “ankle replacement” still retain greater engagement by FAOSs. Search engine optimization and saturation strategies should be considered.

Level of evidence:

Level 3 (observational study).

Teknolojinin gelişmesi sonucunda hayatın her alanına kaynaklık eden sosyal medya karşılıklı bilgi paylaşımının olduğu, eş zamanlı bir iletişim aracıdır. Gelişen internet teknolojileri, kullanıcıların teknik bilgiye gerek duymadan içerik oluşturmalarına ve oluşturdukları içerikleri paylaşmalarına olanak sağlamıştır. Sosyal medya; zaman ve fiziki mekân kavramını ortadan kaldıran, kullanıcısının kendi ürettiği içeriği yayınladığı ve paylaştığı çevrimiçi bir ağ olması nedeniyle etik sorunları da beraberinde getirmektedir. Özel yaşamın gizliliği, kişisel verilerin güvenliğinin sağlanamaması, telif/patent hakları, yoğun reklam içeriği, yanıltıcı etiketleme ve gizli reklam uygulamaları gibi birçok problem sosyal medyanın etik sorunları olarak tartışılmaktadır.

Araştırmada, sosyal medya kullanıcılarının söz konusu etik ihlallerin ne derece farkında olduğu ve etik değerlere yatkınlığının belirlenmesi amaçlanmaktadır. Bununla birlikte hızlı bir şekilde büyüyen ve sektör haline gelen sosyal medya paylaşımlarındaki reklamların etik olup olmaması ve bu paylaşımların tüketicilerin satın alma niyetlerini ne derecede etkilediği tartışılmaktadır. Nicel araştırma yöntemi olarak anket tekniği, veri toplama aracı olarak anket formu kullanılmıştır. Anketler internet yolu ile dağıtılmış olup 653 adet anket değerlendirmeye alınmıştır. Veriler SPSS istatistik programına kaydedilerek analiz edilmiştir. Yapılan analizler sonrasında etik değerlere yatkınlık ile reklama yönelik değerlendirmeler ve tüketici satın alma niyeti arasında anlamlı bir ilişki bulunmamıştır. Buna karşılık reklama yönelik değerlendirmeler ile tüketici satın alma niyeti arasında anlamlı ilişki olduğu görülmüştür.

Bồi dưỡng thường xuyên là nhiệm vụ bắt buộc đối với giáo viên nói chung và giáo viên phổ thông dạy tiếng Pháp nói riêng. Bài viết này tổng hợp kết quả nghiên cứu từ một khảo sát định lượng trên những giáo viên tiếng Pháp bậc phổ thông ở miền Nam nhằm tìm hiểu đánh giá của giáo viên về các đợt bồi dưỡng đã tham dự cũng như nhu cầu bồi dưỡng thường xuyên của bản thân. Kết quả nghiên cứu cho thấy đây là một nhu cầu thực sự đối với giáo viên, và các đợt bồi dưỡng thường xuyên đã đáp ứng phần nào nhu cầu của phần đông giáo viên. Tuy nhiên, bên cạnh đó vẫn có những điểm khác biệt (tầm quan trọng đối với những nội dung bồi dưỡng, nhu cầu bồi dưỡng, các vấn đề tổ chức…) cần được nghiên cứu và làm rõ.
Analysis of Native English Speakers’ Perceptions on English Conversation Class at the College Level
Authors:   Liberal Arts Innovation Center, Kim Sook Hyun
Published: June 2022

The purpose of the study is to analyze the perceptions of native English speakers conducting English conversation classes as part of general English education at a local university. A total of 21 native English speakers participated in the survey after completing the semester. The survey was categorized into four different groups, namely inquiries about the students’ purpose of taking the class, satisfaction of the curriculum, expectation for the students after taking the class, and the suggestion to improve the curriculum of English conversation class. The survey had open-ended questions to derive opinions and suggestions for the class. The results showed native English speakers were mostly satisfied with the current curriculum and expected that the students can lower the anxiety and raise the interest and motivation in learning English after taking the English conversation class. Native English speakers suggested that it is necessary to have differentiated classes based on students’ English speaking level. Classes including both high and lower level students at the same time are difficult for professors to manage and also make it difficult for students to participate with motivation and interest. The curriculum of the English conversation should adopt opinions and suggestions of the native English speakers who conduct the actual classes.
