Looking From a Window: A Critical Analysis of the T'boli's Worldview Through their Oral Traditions
Authors: Casinto Carlo Domingo
Published: March 2022

This study analyses a collective worldview through the values embodied in the oral traditions of the T'boli, an indigenous tribe in Lake Sebu, the Philippines. Utilising ethnographic method, data collection is made primarily through informants' in-depth interview and literary criticism of the oral traditions. The study records, transcribes, translates, codes and classifies the T'boli's oral traditions according to their genre. Framed under Carl Jung's Archetypal Criticism's perspective, it identifies T'boli's religious,  human, and cultural values in the mythical characters and in the recurring motifs and themes of their oral traditions. The prominent motifs in T'boli's oral traditions are the controlling imageries of a deity and a body of water. The recurring didactic teachings in the themes are devotion, altruism, and deference. The embodied values are faithfulness, generosity and respect and obedience to authority. These values shape the T'boli's worldview in terms of their cultural and religious practices and traditions.
Comparison of mechanical and chemical weed control in sugar beet – Impact on pest insects and epigaeic predatory arthropods
Authors: Weller Jessica , Lehmhus Jörn
Published: March 2022

In 2019 to 2021, effects of different weed control strategies in sugar beet on pests and beneficial insects were examined at seven locations in Lower Saxony. The different strategies included conventional spraying, band spraying in the row together with mechanical hoeing between the rows and mechanical hoeing between the rows along with hand hoeing in the row. The various beneficial and pest insects were caught using different trapping methods. For the majority of arthropod populations, either no differences or hardly any significant differences were reported between the three different weed control strategies. Significant effects could only be found on single dates, but these were also not directed in the same direction. According to the results from the photoeclector catches and visual assessments, hoeing three times and chemical weed control had comparable effects to the on the arthropod populations evaluated in this study.

The Sukajaya Sub-District Office, several staff who helps in the finance department also has an educational background of high school graduates. This study aims to analyze the influence of human resources on the quality of financial reports at the Sukajaya Village Office, Palembang City. This study uses secondary data in the form of observations (observations). The results showed that the Sukajaya Village Office already had human resources in accordance with the field assigned, namely the financial sector, although not all parties had an undergraduate education background, namely a minimum of high school. Human Resource Competence is the ability of an employee related to knowledge, skills, and attitudes in completing their performance so that they can achieve the desired goals. The Sukajaya Sub-District Office, Palembang City should provide training to staff related to the financial sector so that later they are able to carry out functions related to the financial sector.Â Keywords: Human Resources, Quality of Financial Reports
Creating Audio Books for Children with Visual Impairment: The Collaborative Approach Leading to Virtual Learning
Authors: Guha Smita
Published: March 2022

Collaborative learning encourages active learning opportunities. The concept of virtual learning was established to enable students to learn across international boundaries. Audio books can be an invaluable learning medium for children with visual impairment. The specific aim of this project was to help the children with visual impairment in India to learn spoken English in an interesting and engaging manner. The purpose of the study was to create collaborative learning opportunity for six graduate students enrolled in an early childhood course at a university on a digital platform to promote virtual learning to make audio books for children with visual impairment in India. Audio books were developed collaboratively by the students and then were sent electronically to the School for the Blind. During the collaborative project, not only did the students receive feedback from the instructor but also received constructive comments from each other throughout the process. Data was analyzed qualitatively. The important conclusion of this case study approach was the learning outcome of the students who felt it was a time-consuming effort, but a rewarding experience.
Implementation of SDGs in higher education institutions as a key stage in the development of modern education
Authors: Yakovleva Olena , Kushnir Olha
Published: March 2022

Modern education requires its stakeholders to understand the present and the immediate future needs. After all, the training of specialists takes place according to the needs of employers and society as a whole. Education has always carried a value basis formed the worldview of those who studied. Since 1992, education has been included in the main directions of global development, and in 2015 it was formulated as goal 4. In addition to declaring equal access to quality learning, it also includes learning other sustainable development goals, and it has a value component. We analyzed approaches to education, on the one hand, in international organizations, on the other hand, in a private educational institution. Here we will show how the design of sustainable development goals at the international level has influenced the awareness of its educational mission in a particular institution of higher education. Education gradually transforms from a classical one, which distances itself from the social situation to an integrated one in social life. Modern education involves business and industry representatives, politicians, and government officials, adapts curricula to business needs, and introduces valuable educational components. All students acquire the knowledge and skills necessary for sustainable development, including through education for sustainable development: appropriate lifestyles, protection of human rights, gender equality, promoting a culture of peace and non-violence through global civic education, and recognition of cultural diversity and cultural contribution to sustainable development.
Exploring Student Perceptions of Self-Access Learning for Active Learning: A Case Study
Authors: Warrington Stuart D.
Published: March 2022

Despite much being written about self-access learning and active learning, both still remain definitionally evasive concepts. How both are conceptualised is very often dependent upon how they are interpreted within the context they are implemented in. Hence, making sense of the relationship between self-access learning and active learning poses a problem, especially considering the dearth of literature available. With these points in mind, this study explored unknown, unexpressed, and unascertained student understandings of self-access learning to gauge what these suggest for enacting active learning at one private Japanese university. This was done via a qualitative case study using an open-ended survey with 53 Japanese university students majoring in English. The findings showed that learners have a vague conception of self-access learning, seeing it as an environmentally-situated behaviour where they are free to do what they want despite often being unclear about how to use their time and having no clear learning plans. These behaviours, taken together, suggest active learning is unlikely to emerge without initial learner comprehension and acceptance of self-access learning. Moreover, it is likely these cannot be enacted if the right kind of administrative support is not provided.
Launching a Tutoring System Within a Restructured Self-Access Language Learning Center in Japan Amidst a Pandemic
Authors: Ristea Viorel
Published: March 2022

This paper examines the inaugural year of a rebranded and restructured self-access learning center (SALC), launched at a provincial university in Japan towards the beginning of the COVID-19 pandemic, with a focus on implementing, promoting, and managing a tutoring system, both online and face-to-face, while facing the challenges and limitations imposed by the pandemic. Even though the pandemic has forced most traditional face-to-face classes and on-campus activities online, there is still little research concerning online self-access services in Japan, as also noted by Davies et al. (2020). Existing research on SALL in the pandemic tends to focus on well-established SALCs. This paper aims to fill this gap in the literature by also discussing the challenges of online tutoring and revealing the solutions to overcome those challenges over the course of a whole academic year in a new SALC. Finally, it hopes to provide an insight into the management process, together with the administrative challenges faced by the researcher, acting as the sole tutor and coordinator of the SALC.

Published: March 2022

This study aimed at determining the drivers of access to credit among smallholder farmers in Uganda. Using a cross-sectional survey, data were collected from 374 farmers in Jinja district, followed by data analysis using descriptive statistics and Binary logistic regression model. Additionally, we used Chi-square and t-test to compare farmers with and without access to credit. The results showed that 62.83% of the farmers had access to credit. Additionally, farmers with access to credit were generally better off than those without access to credit. Having a mobile phone (p<0.01), group membership (p<0.01), access to extension (p<0.05), farm size (p<0.01) and distance to the market (p<0.05) had a positive and significant effect on credit access while non-farm income (p<0.05) showed an inverse relationship with credit access. To increase credit access among the smallholder farmers, farmers should be encouraged to purchase mobile phones and join groups where they would disseminate information on the various source of agricultural credit. Extension workers should also make effects of reaching all the farmers and training them on ways of accessing agricultural credit.
Gender Prejudices in Ekegusii Language: A Case of Proverbs/Wise Sayings
Authors: Mose Edinah Gesare
Published: March 2022

The advent of the twentieth and the twenty first century has seen languages embrace gender neutrality consciously and these changes in languages have contributed to gender equality. In this regard, the power of languages cannot be ignored in shaping people’s social constructions and their roles in societies. Studies have indicated that languages have the power to create and enforce gender determinism and the marginalisation of the feminine gender. Currently, both English and French have embraced inclusivity, whereby there is a deliberate attempt to move away from the use of the masculine as the default form for nouns, to the use of gender-neutral words. This may not be the case for many other languages of the world. That is why this article investigated the use of prejudiced language in Ekegusii paying particular attention to proverbs or wise sayings. Specifically, the article investigated the gender inferences, the roles and the stereotypical constructions in the proverbs or the wise sayings. It also investigated the effect of these gender inferences on the users’ perceptions in constructing their identities as men or women. The Social Constructionism Theory guided the analysis while a descriptive field linguistic design was used. Judgemental sampling was then used to sample proverbs from the Ekegusii dictionary and thereafter analysed them to determine the gender inferences, the roles, and the perceived gender constructions. The findings revealed that the figurative language used in these proverbs had underlying gendered prejudiced language that perpetuates historical patriarchal hierarchy that denotes men as norm. Further, the gendered prejudiced language outlines roles that influence members of the society to conform to specific societal expectations in line with their gender therefore forming stereotypes. Proverbs or wise sayings mirror essentially, a culture of a given people. Their continued use indicates one’s prowess in a given language and it is deemed prestigious. Therefore, it is hoped that the findings herein will awaken the users on the gendered ideologies in some of the proverbs so that even as they use them, they may conform to the modern trends of gender-neutral language.
EU-NATO and the Eastern Partnership Countries Against Hybrid Threats (2016-2021)
Authors: Ratsiborynska Vira
Published: March 2022

The EU, NATO and the Eastern Partnership countries
are facing a range of security challenges and risks. Hybrid threats are a
permanent feature of today’s security environment and a part of the current EU,
NATO, and the Eastern Partnership countries security landscape. In a period of
rapid changes in the security environment and external pressures, it is
important to intensify cooperation between the EU, NATO, and the Eastern
Partnership countries and to make further progress on common collaborative
approaches against hybrid threats. The paper focuses on different areas of the
EU-NATO cooperation against hybrid threats and argues that shared resilience
against shared threats can lead to a better synchronization of efforts in
countering hybrid threats. A case study on the Eastern Partnership countries is
introduced in this research and is examined in the paper.
The War in Ukraine Through the Prism of Presidential Decision-Making Processes, vis-a-vis Media & Cyber Warfare
Authors: Bouks Barak
Published: March 2022

The war in Ukraine is characterized by personal
decision-making processes: President Putin who was born and raised in the
Soviet-Union while witnessing its collapse, hence his prism is of reviving his
country's status versus the west. President Zelensky of Ukraine is an actor who
played the "role of his life" on a TV series, only to be elected
genuinely for this position. The war catapulted his status as he visited his
troops in the front waring uniform. Some key characteristics of the war are media
(disinformation) and Cyber warfare (aimed at security, economic and national
infrastructure). The solution for this catastrophic calamity, should not be
based solely on imposing economic sanctions on Russia, but through using the
services of an effective mediator as the Israeli PM Naftali Bennett, who
visited Russia on March 6, 2022. His initiative can assist arriving at a common
denominator of preserving the safety of Ukraine through imposing an immediate
ceasefire on the one hand, while acknowledging Russia's red lines of not
allowing Ukraine to be aligned with the west, on the other. Meanwhile, until
the war will be halted, it is an imperative to define a humanitarian
governorate under western control which will serve as a safe haven for the
refugees.
The Strategic Relevance Of The Mediterranean
Authors: Cinciripini Luca
Published: March 2022

The Mediterranean is
usually observed as a gateway to Europe, mainly in terms of migratory
processes. Over the last few years, the progressive shift of interest to Asia
by the United States has led to new opportunities for competing regional
players, which affect the local security framework. In this new scenario, the
Mediterranean takes on relevance no longer only as a gateway to Europe, but as
a crucial strategic area for the penetration of the African continent. The
latter has long been known as the incubator of the new jihadist threat, which
is finding new life and increasingly assuming the characteristics of a hybrid
threat. In such a crisis scenario, the security of the Mediterranean is no
longer limited to the coastal countries of North Africa but inevitably includes
the Sahel area. Here, for years now, the progressive formation of a united
front of instability has been observed, crossing Africa from the east to the
west coast (here called the "Black Belt Road"), through the bridging of different crises. Considering the
European and Italian military presence through operations Barkhane and Takuba,
the security of the Mediterranean directly affects the future scenarios of
Western military involvement in the African continent.

Authors: Naito Yuki , Shida Naoki , Atobe Mahito
Published: March 2022

We have successfully synthesized piperidine and pyrrolidine derivatives by electroreductive cyclization using readily available imine and terminal dihaloalkanes in a flow microreactor. Reduction of the substrate imine on the cathode proceeded efficiently due to the large specific surface area of the microreactor. This method provided target compounds in good yields compared to a conventional batch-type reaction. Furthermore, piperidine and pyrrolidine derivatives could be obtained on preparative scale by continuous electrolysis for approximately 1 hour.

Published: March 2022

This study aimed at investigating the perceptions of tertiary students about online learning strategies in the Remote Learning Environment during the Covid-19 pandemic era. The method used in this research was a descriptive qualitative method by using a survey to collect the data from 20 tertiary students’ perceptions of their online learning strategies in rural areas during this pandemic era. The results indicated that students agreed with online learning strategies with digital platforms but they are still confused about how to learn and access them. Virtual meetings declined students’ motivation to learn because of bad access to the internet in their areas. Using Video Conferences is more flexible because it can be used wherever whenever. Online learning still becomes the best learning strategy in this pandemic, but access to the internet in rural areas must be improved. Tertiary students need access to the internet and infrastructure and instructional materials design especially applied in this pandemic era. In conclusion, online learning strategies by using digital platforms still become the best solution to be applied in the remote learning environments during this Covid-19 outbreak, even there are some obstacles still existed.

Published: March 2022

Main objective of this study assess and evaluate energy literacy cognitive in difference system schools in Indonesia, namely are general public school, general private school, islamic public school and islamic private school based on scope of study and gender. A questionnaire was designed to check the cognitive to 64 students from four different senior high school. This study used frequency distibution and independent t-test as analysis and use SPSS software for helping calculating the questionnaires. The overall energy literacy cognitive level is dominant in very poor level (59.4%). One of the reason energy literacy in very poor level cause most of the parents' educational backgrounds are high school graduates (44%), also 41% their parents' educational backgroud are elementry and junior high school and there are only 13% in university. Students in general school study about energy three times in a week than in islamic school is just twice in a week. Therefore, it seems normal when energy literacy in general school is higher (mean value 34) than in islamic school (mean value 32) and it also happened between public school and private school, which public school has 35 and private school has 30. In science class, energy literacy is higher than social class that is caused students in science class study about energy on physics subject and chemistry subject, whereas in social class students study energy on geography, but it is not much as in physics and chemistry subject.

Authors: TÜRKMEN SARIYILDIZ Gülçin , ÇİÇEK Canan , ARSLAN Aykut İlker , DEMİR Mehmet Emin
Published: March 2022

Aim: It has been indicated that COVID-19 is related to many endocrinological abnormalities. The aim of this study is to demonstrate whether there is an impact of COVID-19 and COVID-19 vaccines on development of subacute thyroiditis (SAT).

Material and Method: This retrospective single-center study includes individuals with SAT who were diagnosed between March 2020 and August 2021. Patients were evaluated for a recent Covid-19 history and SARS-CoV-2 vaccination. SAT was diagnosed based on the clinical presentation and laboratory tests; including thyroid function tests, sedimentation rate, C-reactive protein, and thyroid ultrasound. SARS-CoV-2 PCR results of patients with past COVID-19 were obtained from the Ministry of Health electronic patient data system. Type, number, and dates of vaccine doses were recorded for each participant.

Results: A total of 31 patients were included in the study. Six patients (19.4%) were diagnosed with SAT following a COVID-19 vaccination schedule. Four patients with SAT had received two inactive (CoronaVac) + one dose of mRNA vaccines (Pfizer-BioNTech). The other 2 patients had received either two doses of inactive vaccine or two doses of mRNA vaccine. Five patients were diagnosed with SAT after the second dose of the vaccine. The median interval between last vaccination dose and diagnosis of SAT was 25.8 days. In one patient, SAT developed 28 days after the mRNA vaccine. Seven patients (22.6%) were diagnosed with SAT after COVID-19 disease. The median interval from the diagnosis of COVID-19 disease to SAT was 27.3 days. All cases of post-COVID-19 and post-vaccination SAT patients exhibited similar clinical presentation and findings to idiopathic SAT.

Conclusion: Covid-19 itself and Covid-19 vaccines might let a tendency to development of subacute thyroiditis. This study has to be supported by further studies.
Physical and Chemical Properties of the Molecular Gas Associated with the Mid-infrared Bubble S156
Authors: Yu Nai-Ping , Xu Jin-Long , Zhang Chuan-Peng , Jiang Peng , Liu Xiao-Lan , Wang Jun-Jie
Published: March 2022

Using archival infrared data of GLIMPSE, Hi-GAL, and molecular line data of SEDIGISM, MSGPCOS, and MALT90, we investigate the physical and chemical properties of the molecular gas associated with the mid-infrared bubble S156. By the method of spectral energy distribution, we made H2 column density and dust temperature maps of this region. We find two clouds with masses of 5.4 ± 1.1 × 104
M
⊙ and 2.2 ± 0.5 × 104
M
⊙, respectively. In both of the two clouds, the 13CO (2–1/1–0) and 13CO (2–1)/N2H+ (1–0) intensity ratios are enhanced on the boundary. Cloud A has a clear dust temperature gradient decreasing from the boundary to the outside region. Our analysis indicates cloud A is mainly influenced by the feedback from S156, while cloud B is affected both by S156 and the G305 complex. We also find the 13CO and C2H emissions tend to be brighter in photon dominated regions (PDRs), while N2H+ is brighter in the regions of cold gas that is far away. Furthermore, we make the abundance maps of C2H and N2H+ of cloud A. We find the abundance of C2H is enhanced in the region facing ionizing stars and it decreases steadily moving away from them. On the other hand, the abundance of N2H+ increases from the ionized boundary to the cold gas outward. These phenomena indicate C2H prefers to be produced in hot gas such as PDRs, while N2H+ could be destroyed by it. Our study also suggests the abundance ratio of C2H to N2H+ could trace PDRs in the late stages of massive star formation.

Multiband optical photometry data of blazar S5 0716+714 obtained from 2002 to 2019 reveal stable color index change with flux variability. We analyzed this trend under variability caused by the Doppler factor change in the presence of a curved photon energy spectrum. A break in the energy spectrum of emitting electrons, caused by radiative losses, or log-parabolic electron energy distribution, or the synchrotron self-absorption acting in a compact jet part forms such the photon spectrum. We explained the observed color index change with variability by geometric effects only under the assumption that the radiating region is the synchrotron self-absorbed core and the bright optically thin jet. In this framework, we estimated the magnetic field strength in the optically thick part of the radiating region. These values correspond to other independent estimates of the magnetic field near the black hole, further supporting our assumption.

are typically not individually detected, particularly at higher redshifts (z ∼ 1–2) where galaxy clusters are undergoing rapid transitions from hosting mostly active, dust-obscured star-forming galaxies to hosting quiescent, passive galaxies. To account for these undetected galaxies, we measure the total light emerging from GALEX/near-UV stacks of galaxy clusters at z = 0.5–1.6. Combined with existing measurements from Spitzer, WISE, and Herschel, we study the average UV through far-IR spectral energy distribution (SED) of clusters. From the SEDs, we measure the total stellar mass and amount of dust-obscured and unobscured star formation arising from all cluster-member galaxies, including the low-mass population. The relative fraction of unobscured star formation we observe in the UV is consistent with what is observed in field galaxies. There is tentative evidence for lower than expected unobscured star formation at z ∼ 0.5, which may arise from rapid redshift evolution in the low-mass quenching efficiency in clusters reported by other studies. Finally, the GALEX data place strong constraints on derived stellar-to-halo mass ratios at z < 1, which anticorrelate with the total halo mass, consistent with trends found from local X-ray observations of clusters. The data exhibit steeper slopes than implementations of the cluster star formation efficiency in semianalytical models.

Fast radio bursts (FRBs) are mysterious transient phenomena. The study of repeating FRBs may provide useful information about their nature due to their redetectability. The two most famous repeating sources are FRBs 121102 and 180916, with a period of 157 days and 16.35 days, respectively. Previous studies suggest that the periodicity of FRBs is likely associated with neutron star (NS) binary systems. Here we introduce a new model which proposes that periodic repeating FRBs are due to the interaction of a NS with its planet in a highly elliptical orbit. The periastron of the planet is very close to the NS so that it would be partially disrupted by tidal force every time it passes through the periastron. Fragments generated in the process could interact with the compact star through the Alfvén wing mechanism and produce FRBs. The model can naturally explain the repeatability of FRBs, with a period ranging from a few days to several hundred days, but it generally requires that the eccentricity of the planet’s orbit should be large enough. Taking FRBs 121102 and 180916 as examples, it is shown that the main features of the observed repeating behaviors can be satisfactorily accounted for.
An intelligent recognition framework of access control system with anti-spoofing function
Authors: Wang Dongzhihan , Ma Guijin , Liu Xiaorui
Published: March 2022

Under the background that Covid-19 is spreading across the world, the lifestyle of people has to confront a series of changes and challenges. This also presents new problems and requirements to automation facilities. For example, nowadays masks have almost become necessities for people in public places. However, most access control systems (ACS) cannot recognize people wearing masks and authenticate their identities to deal with increasingly serious epidemic pressure. Consequently, many public entries have turned to an attendant mode that brings low efficiency, infection potential, and high possibility of negligence. In this paper, a new security classification framework based on face recognition is proposed. This framework uses mask detection algorithm and face authentication algorithm with anti-spoofing function. In order to evaluate the performance of the framework, this paper employs the Chinese Academy of Science Institute of Automation-Face Anti-spoofing Datasets (CASIA-FASD) and Reply-Attack datasets as benchmarks. Performance evaluation indicates that the Half Total Error Rate (HTER) is 9.7%, the Equal Error Rate (EER) is 5.5%. The average process time of a single frame is 0.12 seconds. The results demonstrate that this framework has a high anti-spoofing capability and can be employed on the embedded system to complete the mask detection and face authentication task in real-time.

This article addresses the problem of estimating the finite population mean using two auxiliary variables under two-stage sampling scheme. Further the proposed improved class of estimators are provided their genralized form. Mathematical properties of the existing and proposed improved generalized class of estimators are derived up to first order of approximation. We identified 11 members of the improved generalized class of estimators which are more efficient than existing estimators in terms of the percentage relative efficiency. We use two real data sets under two-stage sampling to compare the performances of all of considered estimators.
Selection of Audio Learning Resources Based on Big Data
Authors: Wang Peng , Wang Xia , Liu Xia
Published: March 2022

Currently, audio learning resources account for a large proportion of the total online learning resources. Designing and implementing a method for optimizing and selecting audio learning resources based on big data of education will be of great significance to the recommendation of learning resources. Therefore, this paper studies a method for selecting audio learning resources based on the big data of education, with music learning as an example. First, the audio signals were converted into mel spectrograms, and accordingly, the mel-frequency cepstral coefficient features of audio learning resources were obtained. Then, on the basis of the conventional content-based audio recommendation algorithm, the established interest degree vector of target students with respect to music learning was expanded, and a collaborative filtering hybrid algorithm for audio learning resources that incorporates the interest degrees of neighbouring students was proposed, which effectively improved the accuracy and stability in the prediction of students’ interest in music learning. Finally, the experimental results verified the feasibility and prediction accuracy of the proposed algorithm.
The production of social school democratic spaces for agency transformation
Authors: Liberali Fernanda , Tanzi Neto Adolfo
Published: March 2022

This article discusses the production of social school democratic spaces for teachers’ and students’ agency transformation in a Latin American globalized context – Brazil, through their participation in an engaged multiliteracy project (Digitmed Program/Brazil), where some social, political, economic, and cultural issues are at the basis. In this program, there are all types of social exclusion such as age, gender, class, race, hearing differences; oppressions lived by educators and students; children and teenagers who work on streets as opposed by others who have a very limited perception of the surrounding reality; students involved with drugs, both as users and as dealers, students who consider suicide as an option, and other similar dramatic circumstances. The project involves a critical-collaborative intervention research (Magalhães, 2011) with private and public (municipal and state) schools, focusing on a university-school-community partnership for the joint construction of a school democratic social space for agency transformation. In this project, the concept of agency offers us basis to investigate the development of individuals in the critical transformation process of their social realities through engaged multiliteracy.

O uso de um instrumento de autorreflexão em um contexto de formação inicial de professores de línguas com vistas ao desenvolvimento do letramento crítico e à transformação social – a autonomia sociocultural, as tecnologias e suas inter-relações

Neste estudo, utilizamos um instrumento de autorreflexão para a implementação de uma prática pedagógica direcionada à reflexão crítica. Com isso, buscamos compreender o desenvolvimento do letramento crítico na formação inicial de estudantes de Letras a fim de fomentar reflexões sobre a educação linguística relacionadas à autonomia sociocultural e ao uso da tecnologia e suas interrelações. Para isso, construímos e aplicamos um instrumento autorreflexivo para 30 alunos de Letras. Utilizamos o software Atlas.ti para atribuir categorias de análise. Os resultados, obtidos a partir das discussões sobre letramento crítico, apontam que instrumentos autorreflexivos podem fomentar a reflexão crítica e promover oportunidades para a problematização de conceitos e concepções. Quanto à concepção de autonomia, as reflexões dos participantes demonstram uma tendência de se perceber a autonomia no sentido individual, embora, no sentido coletivo, o conceito de autonomia sociocultural possa ser novo para esses professores. As reflexões sobre tecnologias digitais, por sua vez, apontam que, ainda que as tecnologias possam ampliar as oportunidades de aprendizagem, o acesso a elas somente por uma camada social privilegiada tende a aumentar a desigualdade social.  Como consequência, apenas um grupo restrito tem sua voz ouvida, o que acaba coibindo possíveis processos emancipatórios de classes menos privilegiadas, dificultando a transformação social da sociedade. Concluímos, assim, que há um desejo por parte de professores de línguas em formação que a educação linguística tome rumos que levem à formação de cidadãos(ãs) críticos(as), empenhados em construir uma sociedade com menos desigualdades sociais e mais oportunidades para todas, todos e todes.
