Authors: Saputri Wulandari , Priyambodo Panggih , Budi Setia , Armanda Fahmy
Published: May 2022

Retention is the key to the success of a learning program. Several studies have shown that retention can be influenced by metacognitive skills, critical thinking, cognitive learning outcomes, and applied learning models. Meanwhile, testing the relationship between the three factors mentioned above and retention is only done using simple and multiple regression with two factors. This correlational study was conducted to determine the relationship between three factors, namely metacognitive skills, critical thinking, and cognitive learning outcomes on retention in students taught by RQA and QASEE learning models, as well as conventional learning. A total of 107 pre-service teachers of Biology Education students in South Sumatra, Indonesia, were involved in this study. The results showed a relationship between metacognitive skills, critical thinking, and cognitive learning outcomes with retention in students who were taught the RQA learning model. However, in the QASEE learning model and conventional learning, this relationship was not found. Thus, it can be concluded that more than two factors affect retention. Then, applying the appropriate learning model also influences the success of a learning program. Finally, conventional learning that only emphasizes efforts to get students to pass the exam must be abandoned immediately.

Published: May 2022

This study presents Augmented Reality (AR) implementation for learning geometry mathematics with a cultural approach in junior high schools. The research method used was ADDIE (analysis, design, development, implementation, and evaluation) by limiting it to (1) exploration analysis, (2) design, (3) development, and (4) implementation. Applying the AR concept to the mathematics learning method with a cultural approach is hoped to create an interesting and fun mathematics learning atmosphere. This is because the application of AR concepts in mathematics learning can help students towards abstract mathematical concepts with the help of 3D objects and improvisation of appropriate sounds and images. The research results are an AR application prototype for learning geometric mathematics with a cultural approach in junior high schools, which can be used for geometry material in junior high schools for both classroom and online learning.

Authors: Raja Fransiskus Dinang , Suparno Suparno , Ngadiso Ngadiso
Published: May 2022

The multilingual world demands educational stakeholders to adjust by embracing multilingual pedagogies. Translanguaging is deemed a prominent language practice to be implemented in educational settings, especially in the EFL class. However, the practice still obtains criticisms. Many scholars point out challenges in implementing classroom translanguaging. Therefore, studying attitudes, specifically students' attitudes, becomes significant at this point because it helps to reveal how students' feelings and thoughts of translanguaging practice are based on their learning experience. Further, their attitudes can be considered in the classroom decision making whether to translanguage or not to translanguage. The present study will generally continue what previous scholars have done but in a new context and methodology. This study investigated students' attitudes towards student- and teacher-directed translanguaging in Indonesian EFL classrooms. The participants were 40 grade VIII students from two EFL classes of a private boarding school located in East Nusa Tenggara, Indonesia. The data was collected using online questionnaires consisting of close-ended and mainly open-ended questions. The result showed that most students expressed negative feelings toward students-directed translanguaging. Meanwhile, teacher-directed translanguaging was more acceptable indicated by most students who had positive feelings towards their teachers' translanguaging. Students' arguments and comments were also interesting to be noticed. These findings shed light on a multilingual pedagogical practice and further research, which we would like to discuss further within this article.

Authors: Leasa Marleny , Berbakem Obertina
Published: May 2022

The ability of students to ask or answer questions from the teacher is generally not based on reasoning. Therefore, we need a way to help the development of student reasoning by using empowering thinking through questions (PBMP). Therefore, students gain knowledge from the teacher and are actively involved in the science learning process. This study aimed to determine students' science learning outcomes using the PBMP model with the assistance of the Inshot video. This type of research is quasi-experimental. The participants in this study were 70 students, with 35 for the experimental group and 35 students for the control group. The results showed that learning outcomes with the PBMP strategy were higher with an average score of 81.00 compared to conventional ones with 57.05. Meanwhile, the ANCOVA test results showed a significant difference between student learning outcomes using the PBMP and conventional models. Thus, the PBMP model combined with the Inshot video can be recommended for improving student learning outcomes.

Published: May 2022

In learning conservation biology with online learning communities, lecturers usually guide their students through a discussion-based learning process. In theory, mixed learning can increase interaction in the learning environment. Effective learning is promoted through flexibility, enabling the use of various student learning styles. This study aimed to 1) describe students' creative thinking skills about local wisdom on small islands in Maluku; 2) know the differences in creative thinking skills of experimental class students (using problem-based learning and conventional classes on small islands in Maluku; and 3) knowing differences in students' creative thinking skills on the topic of different local wisdom in small islands in Maluku. This research used the development of 4D Model teaching materials, field lectures, and online-based discussions. The data were analyzed descriptively, and the level of development of the 4D model combined with the student's PBL was evaluated using the normalized N-Gain g, while the quantitative data were analyzed through the ANCOVA test. The research findings reveal that competitive and facilitator styles significantly mediated the relationship between technology user acceptance and mixed learning on students' creative thinking skills. One of the weaknesses found in this study was the geographical differences between the islands. The internet facilities owned by students were not evenly distributed, and the needs of media were various. Blended learning was somewhat challenging to be applied in optimal learning. Scaffolding was given to students to concentrate more on education and independent activities. According to students, problem-based learning, creative thinking, finding information, and writing reports were problem-solving features that contributed the most to student learning.

Authors: Hasbullah M Afif
Published: May 2022

The notion of MBKM allows students to choose their learning activities. It takes the willingness of lecturers to respond to this policy to succeed. In the development of the MBKM, there are pros and cons and cons in the community, so a clear legal umbrella is needed to accommodate the policy. This study uses an approach with data collection through library searches sourced from electronic journal articles. After getting a number of articles, the articles that meet the requirements with a data inclusion strategy are selected and then analyzed descriptively. From the selection process, 10 articles were taken as the data and analyzed using content analysis. The results of the study show that the independent campus policy is a government breakthrough in providing autonomy and independence to each university from complicated employees and also giving students the freedom to choose their own study program. In its development, this policy took the form of reaping the pros and cons in the community so that several legal umbrellas were made that could accommodate them, but in the author's view the legal umbrella is still very important because only ministerial regulations need to be made such as laws or higher regulations of government.

The Discovery of the Implicit Pupil-Teacher Social Contract
Authors: Looker Benjamin
Published: May 2022

The study takes a critical realist grounded theory approach to explore the intersection of pupil-teacher relationships and school alienation using experiences of pupils and teachers. Qualitative data were collected through semi-structured interviews with both pupils and teachers. Participants’ perceptions and experiences were explored, both positive and negative, to develop an understanding of the perspectives of both actors in reciprocal relationships. The methodological framework for this grounded theory diverges from the popular constructivist design and is, instead, influenced by the classic approach. It is developed to be situated in a critical realist philosophy, emphasising the importance of the emancipatory goal of critical realism. Analysis of the data identified that alienated pupils frequently have difficult relationships with their teachers and discovered a subgroup of pupils who experienced more extreme forms of alienation. An implicit pupil-teacher social contract is presented, describing the emergence of observable actions though the causative mechanism inherent to critical realism. The social contract rests upon the concepts of mutual respect and power. When a pupil believes the contract to have been breached, through the perceived violation of one of these concepts, pupil-teacher relationships begin to deteriorate.

Aim: To compare the microvascular and metabolic effects of autologous blood and a balanced electrolyte solution (BES) containing acetate and malate in hemorrhagic shock (HS) in rats. Methods. The experiments were carried out on male Wistar rats (n=21) under general anesthesia. Blood (35% of estimated blood volume) was withdrawn for 5 minutes. After 60 minutes of HS the collected blood was retransfused, followed by the infusion of BES in the volume of 50% of the blood loss (HS+AB group); HS+BES group received BES in a triple volume of blood loss; a sham-hemorrhage control. Heart rate (HR), mean arterial pressure (MAP), skin blood flow (M), gases and acid-base state of arterial blood, post-occlusive reactive hyperemia (PORH) in the rat tail, serum levels of biomarkers S100b and NSE were assessed after 24 hours. After euthanasia, a histological examination of the brain, lungs, heart and kidneys was performed. Results. In HS+AB and HS+BES groups, 24-hour mortality did not differ (one animal in each group). MAP in these groups was moderately reduced compared to sham group. There were no significant differences in HR, M, acid-base state, PORH and levels of S100b and NSE between the groups. Histological examination revealed circulatory disorders of varying severity in groups with hemorrhage, with more pronounced damage to the brain and kidneys in HS+BES group. Conclusion. Both autologous blood and BES containing acetate and malate equally restore MAP, skin microcirculation, and acid-base state 24 hours after HS. However, fluid resuscitation with BES alone is associated with brain and kidney damage.

Baclofen is a muscle relaxant. Due to its pronounced psychotropic effect the drug is often a subject of abuse especially among young people. The article deals with the dynamics of respiratory movement rate and lung histopathology in acute baclofen poisoning. The experimental studies were performed on 20 Wistar rats. The animals were divided into 4 groups (the controls and three experimental groups). The controls included 5 intact rats. The experimental groups included 5 animals each. All of them were treated with baclofen at a dosage of 85 mg/kg. The duration of the experiment was 3, 4,5 and 24 hours, respectively. The frequency of respiratory movements after baclofen intoxication decreased by the 3rd hour insignificantly. Then it increased significantly by the 4,5 hour if compared to the controls and the 3rd hour. Then, by the 24th hour, the frequency of respiratory movements decreased significantly if compared to all the other groups. Within histological study we revealed a complex of pathological changes in the lungs of the rats (circulatory disorders in all the elements of the microcirculatory bed (plethora of capillaries, venules), areas of emphysema, atelectasis and dystelectasis, WBC infiltration of intraalveolar septa and thickening of intraalveolar septa due to edema. Understanding the processes that occur in the lungs after baclofen poisoning will help to improve medical care in these cases. The results of histological study along with the results of chemical analysis will be useful in establishing the fact of baclofen intoxication and the exact moment of the intoxication.

Aim: This article is devoted to the study of current information and the identification of the latest methods of treatment for varicose veins of the lower extremities. Materials and methods: the work is based on the results of a comprehensive examination and surgical treatment of 20 patients with primary varicose veins of the lower extremities and a literature survey. Results: The advanced methods of varicose disease treatment are commonly used and demonstrate highly positive results. In our research 10 patients were operated by radiofrequency ablation, while in the other half sclerotherapy was performed. It’s worth mentioning that in the group of patients who underwent sclerotherapy, there was a minimum percentage (5%) of recurrence of disease. In the case of radiofrequency ablation, no recurrence was observed, which allows us to recommend these methods for the treatment of varicose veins of the lower extremities. Conclusion: Recommendations have been developed for performing operations of various volume and complexity depending on the level of varicose transformation. Modern methods of treatment of varicose veins were discussed, which can be carried out in outpatient departments: they are low-traumatic and have a high cosmetic effect.

Goal: This paper aims to identify optimal transplantation methods for correcting soft tissue defects of the face and mandible based on our medical records and study of up-to-date research literature. Materials and methods: The analysis of standard transplantation procedures was carried out, as well as research of patients charts with extensive defects of the lower jaw at the department of maxillofacial surgery of a Moscow oncological hospital. There was a comparative analysis of the following most popular methods of correction of soft tissue defects of the face and lower jaw: Trapezoidal flap Filatov and H.D. Gillies stem grafting Deltopectoral flap Thoracodorsal flap Temporal parietal flap - Lexer and Esser method Results: Plastic surgery with complex grafts on the neurovascular pedicle is used in the surgical treatment of injuries and diseases of the mandible, which are accompanied by deep defects in the soft tissues of the face and bones of the mandible. The most optimal methods for restoring the anatomical integrity of the mandible, which is necessary for adaptation of the patient in society, and restoration of speech and chewing functions have been identified. Conclusion: Nowadays, the most common and effective methods in the world of eliminating mandibular defects by transplantation are considered to be Lexer’s method (temporal parietal flap), transplantation of the delto-pectoral flap, as well as thoracodorsal on feeding pedicle. The clinical researches conducted in the Moscow Oncological Hospital confirmed generally successful outcomes without complications.

The article presents a clinical case of a rare variant of scarring alopecia - Folliculitis decalvans. It is known that pregnancy provokes or worsens the course of many skin diseases. The given clinical case clearly shows that pregnancy has become a trigger for the development of folliculitis decalvans at the site of a former injury. The article describes the characteristic clinical manifestations of Folliculitis decalvans and its trichoscopic criteria, as well as a review of studies dealing with various methods of the treatment. Any methods of systemic treatment of folliculitis decalvans are undesirable or prohibited during pregnancy, so topical treatment with drugs with proven effectiveness is the option of choice for this category of patients.
