This study evaluated the ovicidal and larvicidal effects of a hydroalcoholic extract (HAE) and two fractions—one aqueous (Aq-F) and the other organic (EtOAc-F)—from dehydrated Cyrtocarpa procera leaves on Haemonchus contortus. In addition, the primary compounds in the HAE and the fractions were identified. The egg hatching inhibition (% EHI) and L3 larval mortality (% Mortality) tests were performed. The treatments used in the EHI test were HAE (12.5–200 mg mL-1), Aq-F (5 and 10 mg mL-1), and EtOAc-F (0.62–10 mg mL-1); for larval mortality, HAE (50–200 mg mL-1), Aq-F (20–40 mg mL-1), and EtOAc-F (2.5–40 mg mL-1). Thiabendazole (0.1 mg mL-1) and ivermectin (5 mg mL-1) were used as positive controls, while methanol (3 %) and distilled water were negative controls. The results were analyzed using a completely randomized design and an ANOVA. The main compounds in the extract and fractions were identified using high-performance liquid chromatography. The HAE had a 100 % ovicidal effect at the highest concentration tested, while EtOAc-F had a nearly 100 % ovicidal effect at 1.25 mg mL-1, and Aq-F displayed the lowest ovicidal effect. Regarding larval mortality, the HAE exerted a larvicidal effect close to 80 % at 100 mg mL-1, while EtOAc-F displayed a larval mortality of 71.47 % at 20 mg mL-1. The chemical analysis indicated the presence of gallic acid, derivatives of gallic acid (gallates), kaempferol rutinoside, quercetin glycoside, and luteolin glycoside. This study shows evidence of the ovicidal and larvicidal properties of C. procera, which could make it useful as a natural anthelmintic in the control of H. contortus.

The non availability or shortage of river sand in some areas affects the concrete construction industry negatively. Hence there is need to find alternatives to river sand and one of the major materials locally available is lateritic soil commonly called laterite. It has been successfully used partially or wholly to replace sharp sand in concrete. This study investigated the relationship between the cube compressive strength and cylinder compressive strengths of laterized concretes made with various combinations of laterite and river sand. Laterized concretes of 1:1½:3 mix proportions were prepared with sand partially replaced with laterite at 0%, 20%, 40%, 50%, 60%, 80% and 100% at a water/cement ratio of 0.55. Granite of 20mm maximum size was the coarse aggregate used; batching was done by weight. A total of 84 cubes and 84 cylindrical specimens were prepared for testing after 3, 7, 21 and 28 days respectively. At each replacement level, the cube crushing strength as well as the cylinder crushing strength of the specimens was determined for proper comparison. At 7 days, the cylinder crushing strength was found to be 72% of the cube strength while for 14, 21 and 28 days they were 77%, 80% and 80% respectively.

Antidepressant Role in Modulating Neurotransmitter Imbalance to Improve Cognitive Impairment in Patient with Alzheimer’s Disease
Authors:   Lebanese University Faculty of Medical Sciences Beirut Hadath Campus, Lebanon, Nasrallah Jamil
Published: February 2024

The present article delves into the complex correlation among neurotransmitter dysregulation, antidepressant therapy, and Alzheimer’s disease (AD). Progressive cognitive decline and neuropsychiatric symptoms are the outcome of AD, the predominant type of dementia, which is characterized by pathological manifestations of β-amyloid plaques and hyperphosphorylated tau tangles. Amyloid plaque formation, tau protein phosphorylation, oxidative stress, and other pathophysiological processes are all aided by dysfunctional neurotransmitters such as acetylcholine, histamine, gamma-aminobutyric acid, and serotonin. On the other hand, medications that treat depression and AD patients turn out to be very important. These include selective noradrenaline reuptake inhibitors (SNRIs), selective serotonin reuptake inhibitors (SSRIs) and atypical antidepressants. Depression and neurologic disorders are correlated in both directions, supporting this treatment approach. The effects of antidepressants include reducing the production of amyloid plaque, improving cognitive function, stimulating neurogenesis, and increasing the levels of monoamine and brain-derived neurotrophic factor (BDNF) in synapses.
Port city states theory of GAYA based on archaeological data
Authors:   The Korean Archaeological Society, Jeong Seonwoon
Published: February 2024

This passage examines the operation and trade patterns of port cities by analyzing the area in the Gaya where foreign elements are concentrated, through the 'Port City States Theory'. To approach the ‘Port City States Theory’ archaeologically, we first defined the concept and attempted to schematize the structure of port cities. Based on this, we were able to establish the developmental stages of ports as 'port of call, trading post, port city, port citystate.‘ As can be confirmed from historical documents and archaeological evidence, the ancient Gimhae Bay area is a region where foreign elements are concentrated. Multiple port cities, not only in the central area but also in the hinterlands, are considered to be organically combined and operated as a port city-state. In the Changnyeong and Geoje regions, a distinct way of life is observed, which can be traced back to related trading posts found in the southern Honam region and the northern part of Kyushu in Japan. It can be observed that Changwon region formed a port city based on iron production, and it appears to have continued its operation even through changes in the dominant groups. In the eastern part of Honam, there is a pattern where foreign elements are concentrated within the indigenous community, indicating that this region was likely used as a trading post due to its location along the coastal routes. After examining the changing patterns of port cities in each region over different periods, it is evident that in the 1st period (from the mid-3rd century to the early 4th century), the port cities in the Gaya region, particularly in the ancient Gimhae Bay area, were developed. In the 2nd period (from the mid-4th century to later), there was an organic combination and operation of the permanent networks in the ancient Gimhae Bay area, and port cities expanded to areas like Changnyeong, Geoje, and Changwon. In the 3rd period (from before the 5th century to the middle of the 5th century), the permanent networks in the ancient Gimhae Bay area began to shrink but continued to operate, and each region also saw a reduction in its size. In the 4th period (after the 5th century), it appears that the port city-like characteristics gradually disappeared in various regions.

Authors: NOYAN Ebru , AŞIK Asuman
Published: February 2024

Foreign language learning has been found effective in helping older people improve cognitive functioning and provide opportunities at psychological and social levels. This study examines the difficulties older adult English as a Foreign Language (EFL) learners and their instructors encounter within the online learning and instruction framework. To achieve this objective, seven EFL learners over 60 and two English teachers were included as participants in the study. The collection of qualitative data occurred over six weeks during an English course. The objective was achieved by submitting participants' weekly self-reflection reports, interviews with learners and instructors, and the researchers' observations. A content analysis was conducted to examine the qualitative data. The study's findings indicate that learners aged 60 and over have several cognitive and physical obstacles when participating in online English courses. Additionally, they rely on their previous learning habits, potentially impacting their overall learning experience. This study provides insights into the pedagogical implications of teaching English to older adults and recommendations for traditional face-to-face classroom instruction and online learning modalities.

Published: February 2024

Sighted and blind individuals live alongside each other in different parts of the world. In the basic principle of being human, sighted and blind individuals are not different from each other. Visually impaired individuals differ from sighted individuals only in terms of their special needs arising from their visual impairment. Meeting these special needs is important for visually impaired individuals to have equal opportunities with sighted individuals in various fields. As a basic human right, both parties need to access to quality and meaningful education. This situation is not different in foreign language education. Hence, this study aimed to explore what visually impaired students have been through in the process of learning English as a foreign language. The participants of the study, which was designed as a narrative research, were 5 visually impaired university students who studied English as a foreign language. In the study, which was designed as a qualitative research, data were collected through semi-structured interviews. The results of the research revealed that visually impaired students have had both positive and negative experiences during their English education.

Introduction: COVID-19 has placed enormous strain on healthcare providers (HCPs). This study aimed to determine the quality of sleep (QoS), and associated factors, of HCPs in primary care clinics during the COVID-19 pandemic. Methods: This was a web-based cross-sectional study of HCPs from 30 primary care clinics in Malaysia. QoS was assessed using a validated single-item scale, and the response ranged from 0 (poor) to 10 (excellent). SPSS version 26 was used for the analysis. Results: Our study included 1280 respondents. The mean QoS score was 6.725 = 1.961. One demographic factor that was positively associated with QoS was age. Having one workplace, nurse, medical assistant, medical laboratory technician (or healthcare assistant compared to being a driver, were also significantly positively associated with QoS. Personality factors that were significantly positively associated with QoS were HCPs’ abilities to cope with work stress and be altruistic. There were negative correlations between QoS and being a male HCP, concern about COVID-19 mortality and perceived risk of exposure to COVID-19. Conclusion: HCPs with clinical roles who were older, had a single workplace, were altruistic and could cope with work stress had better QoS. To maintain the QoS of HCPs, healthcare organisations should promote regular activities supporting the staffs’ mental health and encourage compassion for the organisation and an altruistic work culture, especially among younger employees.

Authors: Ishak Noor Liza , Tan Sui Teng , Hassan Nor Eyzawiah , Alias Azila
Published: February 2024

Langerhans cell histiocytosis (LCH) is a spectrum of disease characterised by proliferation of Langerhans cells causing local or systemic manifestations. We report a two-year old boy who presented with a two-month history of progressive painless swelling over the right zygomatic region with ipsilateral otorrhea. Radiological investigation revealed an expansile hypodense lesion within the temporal bone with erosion of surrounding structures and meningeal enhancement. An ultrasound-guided biopsy of the lesion confirmed the diagnosis of LCH. LCH of the temporal bone may masquerade as otitis media with intra-temporal complications. A high index of suspicion is essential to avoid delay in diagnosis and management.

Published: February 2024

Chronic oral ulcer in patients with rheumatoid arthritis is a diagnostic challenge in primary health care. The possible causes include the disease itself, side effect of treatment, malignancy and infections. This is a case of a 63-year-old woman with underlying rheumatoid arthritis presented with chronic solitary oral ulcer. She was on oral methotrexate (MTX) and high dose folic acid for five years with good compliance. Tissue biopsy showed marked inflammatory cells infiltration and nuclear hyperchromatism with no evidence of malignancy nor infection. The ulcer was resolved after completing antifungal treatment for six weeks following failure of improvement after empirical antibiotic, elimination of possible trauma and discontinuation of MTX. The fungal staining was negative. There are possibilities of false negative results, thus broadened diagnosis with repeated and further investigations are recommended in cases who did not respond to conventional treatment.

Authors: Suddin Leny Suzan , Jamil Ahmad Taufik
Published: February 2024

Introduction: Home injury among the elderly was among the recognized public health issues that could become more prevalent in any nation that would approach an ageing society. However, the community’s perception and preparedness toward the nature of this condition still needed to be improved. This study aimed to determine the community’s profile on unintentional home injury risks among the elderly. Methods: A cross-sectional study was conducted among the community of low-income urban areas in Selangor, using non-probability sampling and a validated self-administered questionnaire covering three domains of risk for unintentional home injuries. Results: 246 respondents participated in this study, with a mean age of 40. The proportion of reported unintentional home injuries among the elderly was 7.3%. Fall was the most common type of injury (72.7%). Of the three domains for risks of unintentional home injuries, only two domains for risks of unintentional home injuries, were significantly associated with the community’s gender (with home safety domain: difficulties in moving things [p=0.027] and difficulties with a staircase [p=0.034]); self-manage domain: concerned when missing medications [p=0.029]), educational level (with self-manage domain: self-care ability [p=0.012] and ability to take balanced diet [p=0.008]), and occupational status (with self-manage domain: concerned when losing weight [p=0.028]) which were home safety and ability to self-manage. Conclusion: The gender and educational level of the community members might reflect different community profiles regarding the risk of unintentional home injuries among the elderly. Thus, to overcome the dangers of elderly unintentional home injuries in the future, policymakers should advocate targeted health education programs for both the elderly population and the community at large.

Published: February 2024

Introduction: Suckermouth catfish are invasive alien species in Malaysia with rapid population propagation, causing negative impacts on the local ecology and economy. Presently, there are no available methods to sufficiently control their populations. The aim of this study is to explore the potential of suckermouth catfish as a source of ingredients for the pharmaceutical industry, which could encourage their utilisation and indirectly control their population. Methods: In this study, acid-soluble collagen extraction was carried out, followed by identification tests, yield calculations, and some basic physical characteristic tests. Results: The extracted collagen was described as off-white and had a strong acetic acid odour. The mean yield of collagen on a wet basis was 10±2.3%, with a hydroxyproline content of 1.6%, while the viscosity and pH of a 20% collagen solution were 0.6±0.25 mPa.s and 5.51±0.1, respectively, comparable to previous studies using various species of fish. Heavy metal contents of the extracted collagen were also found to be within the acceptable limits for use in pharmaceutical and cosmetic applications. Conclusion: This study concludes that the skin of suckermouth catfish is a promising source of collagen for potential industrial applications. However, further studies are needed to improve the yield and purity and establish the physicochemical characteristics, safety, and applications of the extracted collagen.

Da hermenêutica da facticidade:
Authors: Kahlmeyer-Mertens Roberto Saraiva
Published: February 2024

O artigo se ocupa da Hermenêutica da facticidade, do filósofo alemão contemporâneo Martin Heidegger (1889-1976). Nosso propósito inicial é apresentar, sumariamente, os termos do referido projeto filosófico e como este pretende uma abordagem do fenômeno humano enfocado como “vida fática” (faktische Leben). Neste modo de visar, importa para Heidegger a determinação dessa vida, a qual ele denomina de “facticidade” (Faktizität), conceito que, ao longo de sua investigação, vai, progressivamente, ganhando importância e centralidade. Tratado no seio de Ontologia: Hermenêutica da Facticidade (preleção do semestre de verão ministrada na Universidade de Friburgo em 1923), o conceito de facticidade tem lugar no tentame de elaboração de um modo de tornar nosso ser mais claro a nossa própria compreensão. Justamente por isso, uma tal hermenêutica de nós mesmos não constitui uma metodologia de interpretação de um objeto que pretensamente seríamos. Assim, hermenêutica diria, antes, do procedimento que, contando com a compreensão que temos de nosso próprio ser, pode tomar o sentido de nosso factum, de nosso fato de ser. Intentamos evidenciar o quanto a hermenêutica da facticidade é tão hermenêutica quanto também fenomenológica e que, a ideia de “tomar o nosso próprio ser nas mãos”. O artigo ainda se empenhará por deixar claro o quanto a facticidade não é um traço natural, substancial ou essencial do ente que somos; em sua caracterização fenomenológica, tal figura constitui, para Heidegger, uma dinâmica de “fazer-se”, o que nos leva a pensar no caráter em aberto e continuamente criador da vida em seu “dar-se”. Ao fim, ensaiamos, como nosso título anuncia, uma indicação do quanto a hermenêutica da facticidade teria a contribuir para o modo de compreender e comportar-se de uma psicologia fenomenológico-existencial.
Nazewnictwo miejskie jako problem tłumaczeniowy. Analiza wybranych przykładów z oficjalnego portalu turystycznego miasta stołecznego Warszawy
Authors: Szczęsny Anna Małgorzata
Published: February 2024

This paper focuses on urbanonyms as a translation problem. Analyzing the urban names selected from the official tourist portal of Warsaw in the source language (Polish), and their equivalents in the two target languages (English and Spanish), the author indicates the diversity of translation techniques and considers the possibilities of their unification with regard to specific types of naming, taking into account the functional aspect of the text, the needs of the recipient and the purpose of inter-lingual communication. The translation solutions presented, be it unique or repetitive, are illustrative of the difficulties requiring a systemic approach. The author emphasizes the influence of historical tradition on the formation of recognized equivalents, standing in some sense in opposition to the currently most desirable simple and unambiguous localizing equivalents.

Authors: Mounika D , Rao B Eswara , Babji Y , Ambedkar Y R , Rao T Srinivasa
Published: February 2024

The investigation examined the impact of varying concentrations of Cinnamon Essential Oil (CEO) on the preservation of pork sausages. The sausages were divided into different groups: a control group,0.2 µl/g CEO (T1) 0.4 µl/g CEO (T2) and 0.6% µl/g (T3). All these samples were stored at 4°C for 15 days. Notably, the sausages treated with 0.4 µl/g CEO exhibited superior preservation qualities, as evidenced by lower levels of TBARS, free fatty acids, pH, water activity, microbial count (Total Plate Count, coliform count and staphylococcal count) and sensory properties (colour, flavour and overall acceptability) compared to all other treatments (p<0.05). So it can be concluded that the addition of 0.4 µl/g CEO had the most effective preservative impact on pork sausages during the refrigerated storage for a period of 15 days.

Published: February 2024

This paper reports on the effects of two Text-To-Speech (TTS) synthesized speech models, one based on English utterances by a native English speaker and the other based on English utterances by a Japanese non-native speaker of English, on presentation anxiety and self-efficacy of Japanese English as a Foreign Language learners. We hypothesized that learners’ presentation anxiety would decrease and their self-efficacy would increase when using the Japanese non-native English speaker model compared with the native English speaker model. 55 first-year university students (upper level: 33; lower level: 22) voluntarily participated in the study and were divided into experimental and control groups. To measure the participants’ presentation anxiety and self-efficacy, the scale developed by Ishikawa et al. (2021) was used. A mixed-design three-factor ANOVA with the group, class level, and period as independent variables showed an interaction between class level and period. A simple main effect test indicated a significant increase in self-efficacy in the upper-level students. These results reveal that, regardless of the model used, the use of TTS-synthesized speech significantly increases the self-efficacy of the upper-level students. The paper concluded that further research on technology use and learner affect needs to be conducted.
Machine translation in language education: Perspectives from advanced language learners
Authors: Alm Antonie , Watanabe Yuki
Published: February 2024

This paper explores the experiences and perspectives of advanced language learners on the use of Machine Translation Tools (MTTs). The study focuses on how learners navigate their use of tools like Google Translate, DeepL, and Reverso, and how their usage is influenced by instructional recommendations. Nine learners, studying different languages at an advanced level, were interviewed in focus groups. Thematic analysis of the interview transcripts revealed key themes related to the use of Online Language Learning Tools (OLLTs) and MTTs, students' uncertainty about MTT functionalities, policies regarding MTT use, and suggestions for MTT training. The findings highlight the significant impact of initial encounters with MTTs on learners' long-term perceptions and use of these tools. Participants demonstrated strategic use of MTTs to support their reading, writing, listening, and speaking skills, while being aware of their limitations. Although learners found MTTs helpful, they also emphasised the importance of authentic communication in language learning. The study concludes with recommendation for a collaborative approach between teachers and learners to effectively integrate MTTs into the language learning curriculum.
Exercise parameters influencing exercise difficulty
Authors: Heck Tanja , Meurers Detmar
Published: February 2024

Macro-adaptive systems aim to assign practice exercises to language learners that match their proficiency levels. While learner-dependent parameters of exercise difficulty need to be considered online, learner-independent parameters can inform an exercise’s difficulty level in a resource-efficient offline procedure. We present an evaluation of learners’ responses to form-based grammar exercises that aims to identify learner-independent exercise parameters affecting exercise complexity. The results indicate that the exercise type can yield coarse-grained complexity estimates, whereas exercise type specific features can inform more fine-grained estimates. For fine-grained estimates, we show that syntactic variants significantly impact exercise difficulty. Since there is strong variation between learning targets and learners with respect to the impact of different exercise parameters on a learner’s performance, exercise difficulty can only be reliably determined if the exercises are created in a systematic way and by also considering characteristics of the learner.
Attitudes of part-time Japanese university teachers on technology use after emergency remote teaching
Authors: Shiobara Frances Jane , Jolley Kym , Donnellan Mark
Published: February 2024

With the onset of the COVID-19 pandemic in 2020, many Japanese universities made the decision to stop on-campus classes. This generally meant teaching remotely, either synchronously or asynchronously. Online courses are usually planned in advance with a curriculum and materials designed for that mode of teaching. The situation in 2020 was different, most teachers had only a few weeks to adapt their teaching materials and methods for Emergency Remote Teaching (ERT). The aim of this research was to investigate the experiences of university teachers during and after the period of ERT and to investigate how we can learn from this experience to avoid what Vegas (2022) refers to as a ‘missed opportunity’. This was achieved through an initial pilot survey and five semi-structured follow-up interviews conducted in 2023. The results indicated that despite some reporting high levels of initial anxiety, most teachers adapted, learning new skills and developing their technical expertise, which is now being used in face-to-face classes. As most teachers reported support in the period of ERT as having been uncoordinated – being provided by colleagues rather than through official workshops organized by institutions - this is an area that could be developed in the future.
A process-based perspective on the effects of machine translation on L2 writing
Authors: Fonteyne Margot , Daems Joke , Montero Perez Maribel , Macken Lieve
Published: February 2024

Most existing empirical work on the effects of Machine Translation (MT) use on second language (L2) writing has concentrated on its impact on writing products, with much less research addressing its effects on L2 learners’ behaviours during writing. We therefore investigate whether the L2 writing process varies depending on whether learners are provided access to MT or to an online bilingual dictionary. Twenty-seven L1 Dutch learners of Swedish were assigned four writing tasks, with two tasks completed in each condition (MT or dictionary). While writing, participants’ keystrokes were registered. Descriptive measures were used to summarize and compare participants’ writing speed, tool engagement, and pausing behaviour across the two conditions. Results indicated that participants wrote more in less time, consulted the tool more frequently but for shorter periods of time, and paused longer between higher textual units when provided access to MT.

This study explores how students perceive the construction of cultural identity in online intercultural encounters and the impact these perceptions may have on their relationship with English as a Lingua Franca (ELF). This paper presents findings from a mixed-methods study conducted with university students in Germany, France, Israel, and Spain, focusing on English language learning experiences within the context of a Virtual Exchange (VE) project. Results from qualitative data of (n=356) participants indicate considerable differences in how students perceive their roles in intercultural interactions, along with the benefits associated with ELF participation. The results moreover emphasise the importance of reflective practices and open discussions concerning identity construction and language use. The value of initiating dialogues and reflecting identity in the ELF classroom is discussed.
Are digital learning paths sufficient for learning/practising English grammar? Views of secondary school pupils
Authors: Busack Eirini
Published: February 2024

This study aims to investigate 80 grade 6–10 secondary school English as a Foreign Language (EFL) learners’ opinions in Germany about the extent to which they consider Digital Learning Paths (DLPs) sufficient for acquiring or refreshing their English grammar knowledge. The learners were given one to two grammar-focused DLPs, depending on their grade and language level, to complete during their English classes. Upon completion, learners participated in an online survey. Research data were collected in October 2022 using an online survey. Interestingly, results from 80 learners showed that for half of the respondents, the DLPs were sufficient to learn or practise English grammar, but the second half of the respondents indicated that they would prefer DLPs to be integrated into grammar lessons at school. This is because these learners prefer to have additional explanations from the teacher. This case study shows that it can help promote DLPs as an alternative teaching method and encourage EFL teachers to deliver their English grammar lessons in a more engaging and sustainable format.
Investigation of PoodLL ReadAloud in Moodle to reduce the foreign language learning anxiety in English and Japanese language classes
Authors: Ho Maki Terauchi
Published: February 2024

The advantages of learning a foreign language are widely acknowledged, and it is commonly understood that practice is essential for acquiring proficiency. However, learning another language has various obstacles, such as language learning anxiety which hinders students’ learning capabilities. There are many studies to attempt to identify the anxiety provoking factors (Cheng et al., 1999; Khattak et al., 2011; Onwuegbuzie et al., 2000; Sellers, 2000; Zheng, 2008). Recent technological advancement offers many potential methods to empower student learning without anxiety. This study aimed to investigate one such tool, PoodLL ReadAloud activity in Moodle to enhance speaking practice. This study compared the anxiety levels experienced while speaking in foreign language classrooms with those experienced when using PoodLL on a computer, employing questionnaires (Short Foreign Language Classroom Anxiety Scale and PoodLL Anxiety Scale). The anxiety level associated with using PoodLL was lower in first-year and second-year university classrooms, but not among graduate students. Additionally, feedback from the students using PoodLL revealed a positive practice experience, technical difficulties, and scepticism of AI grading. In conclusion, PoodLL shows promise as a tool for practicing speaking skills, however, further research is needed to assess its impact on skill improvement.
Assessing 21st century digital literacies in Japanese higher education
Authors: Healy Sandra , Kennedy Olivia
Published: February 2024

This study examines how the seven digital learner profiles included in the International Society for Technology in Education (ISTE) standards for students apply to 193 participants in Japan, utilizing a questionnaire developed by Mills and White (2023). These profiles explore a broad range of 21st century digital skills, competencies, and literacies essential for learners to be successful in this digital age, and include both creativity and communication. The results revealed positive identification with the learner profiles (M=3.874). While Japanese learners are often found to lack digital skills, the highest mean values were associated with the profiles of Digital Citizen, Knowledge Constructor, and Computational Thinker. In contrast, the profiles of Empowered Learner, Innovative Designer, Creative Communicator, and Global Collaborator demonstrated lower mean values, particularly in more creative and communicative aspects. To ensure students are well-prepared for the digital era, therefore, fostering creativity and communication skills is crucial. There have been a lack of studies that measure the various aspects of 21st century digital skills (van Laar et al., 2020), and this study aims to add to the literature.
Learner corpora and the design of data-driven learning activities
Authors: Forti Luciana
Published: February 2024

This paper seeks to continue the conversation on an underused resource in Data-Driven Learning (DDL), namely learner corpora. It first explores the potential of learner corpora in data-driven learning activity design, focusing on the advantages claimed by a number of scholars throughout the years and mainly associated with the field of Learner Corpus Research (LCR). It then illustrates the status that learner corpus use has in DDL activity design, on the basis of data drawn from the most recent and comprehensive review of DDL research, covering a timespan of 30 years. After describing the main qualitative and quantitative design features of a learner corpus of Italian (i.e. the CELI corpus), the paper shows how learner corpora containing texts produced at different proficiency levels can be used as graded corpora for both target-oriented and error-oriented activities. The sample illustrated activities can thus cater to learners at different proficiency levels, including lower-intermediate and intermediate levels, which are still under-represented in DDL research. Some of the main pedagogical and scientific advantages of using level-specific DDL materials in a paper-based format are also presented and briefly discussed.
Developing LEMI: A new corpus based literacy support tool for schoolchildren
Authors: Rogobete Roxana , Oravițan Alexandru , Chitez Madalina , Csürös Karla
Published: February 2024

This study centres on the developing and testing stages of a literacy support tool dedicated to young schoolchildren. The LEMI tool is currently in development (since January 2023) at the CODHUS research centre (Centre for Corpus Related Digital Approaches to Humanities) from the West University of Timișoara, Romania. LEMI aims to stimulate interest in reading during the first individual and collective reading activities (ages 7-11). This aim will be achieved by creating a digital reading repository with a user-friendly interface that verifies reading text complexity and delivers automatic reading-level reports to users. We use corpus linguistics methods to create a text complexity formula adapted to the Romanian language, which can be integrated into the automated complexity evaluation interface in LEMI. The necessity of such an instrument is motivated by the fact that, in Romania, there are increased rates of functional illiteracy and school dropout. We hypothesise that texts must be level-adapted (according to grade or readability) for schoolchildren to relate positively to reading activities. In the Romanian context, LEMI is the first digital tool wholly tailored to children’s literature, which complements national curricula and didactic materials provided to young children. Distinctively, LEMI responds to the need for easy-to-use tools to adapt reading individually, according to the reader’s profile. LEMI is a unique tool, not only for Romanian but also for children’s literature in other languages. The functionalities of the LEMI pilot version will be tested with the partners involved in the project (three schools from Timiș county and an educational NGO).
Language teacher training in CALL: fostering engagement in an online learning environment
Authors: Carloni Giovanna
Published: February 2024

The present study aims to investigate how effective pre-service language teachers perceived the engagement fostered in an online language pedagogy course. The course was targeted at developing pre-service language teachers’ content-specific knowledge and digital skills through CALL within a language teacher training program implemented at an Italian university. The instructor used various learning environments and teaching methodologies to foster engagement. The data for the study were collected through an online semi-structured questionnaire administered to 33 pre-service language teachers at the end of the course. Findings show that pre-service language teachers deeply valued the high degree of engagement fostered in the course, although some challenges emerged at the beginning.
An investigation of the efficacy of a ChatGPT-powered chatbot
Authors: Donnellan Mark , Wilkins Michael , Linton Kane
Published: February 2024

One of the newest tools for language learning is AI-powered chatbots which allow students to engage in interactive conversations with a chatbot. English Central is a digital language learning platform that allows students to watch videos, study vocabulary, and produce spoken language through short interactive videos. In addition to these three core components, English Central has recently added a chatbot powered by ChatGPT. This paper shares the results of a pilot study that analysed data from Japanese university students who engaged in interactions with this chatbot. The authors introduce quantitative data showing the quantity and quality of the interactions and discuss the strategies they implemented to encourage longer interactions. A student feedback survey was conducted and the results of this are also shared. The results suggested that although many students reported benefits to using a chatbot, the strategies implemented did not lead to significantly longer interactions, and that many students felt frustrated when the chatbot did not understand their utterances.
Using Pimsleur for the self-regulated learning of spoken phrases in Brazilian Portuguese: a case study
Authors: Will Francis , Cardoso Walcir
Published: February 2024

This case study examines the self-regulated use of Pimsleur, a Language Learning Platform (LLP), as a tool to aid in the acquisition of spoken phrases in Brazilian Portuguese (BP) and their related pronunciation. Like many LLPs, research on Pimsleur is scant, as is the number of studies done on BP compared to other major languages. This study aims to address this gap in research. The participant-researcher completed the Pimsleur program through daily study over a 10-week period, after which quantitative data were collected through a post-test and delayed post-test. The results showed that Pimsleur contributed to the learning of the target phrases in the short term and that the participant produced speech that was highly intelligible, moderately comprehensible, but heavily accented. This shows that Pimsleur can be an effective tool for developing spoken BP and can offer a unique learning experience with its methodology and mobile capability that mitigates some of the issues around mobile-assisted language learning (e.g. app attrition).
