Getting to the Nitty-Gritty of Grit: A Descriptive Characterization of Gritty L2 Learners from Thailand, Malaysia, Taiwan and Japan
Authors: Freiermuth Mark R. , Patanasorn Chomraj , Ravindran Latha , Huang Hsin-chou
Published: December 2021

Understanding the make-up of gritty L2 students has garnered quite a lot of attention recently. In this descriptive narrative-based study, we looked at the interview data of eight English language learners who recorded high scores on a nine-item grit questionnaire. Specifically, two female university students each from Taiwan, Malaysia, Thailand and Japan were interviewed and their interview scripts were transcribed and then coded looking for common threads to emerge from the data by applying the tenets of Charmaz’s (2006) Grounded Theory. The data show that beyond perseverance, gritty L2 students enjoy learning the L2, are consistently curious about the L2, are generally not bored by the L2, are confident using the L2 (not letting anxiety dissuade them), are extraverted—encompassing a strong willingness to communicate, have focused L2 vision and have had experiences and/or encounters that bolstered their L2 grittiness. As for encouraging L2 grit development, we suggest that good L2 classroom practice include frequent communicative activities so that students can see the practical side of learning a L2 with the hopes of strengthening their L2 vision.

Authors: Golab Amir , Gooya Ehsan Sedgh , Falou Ayman Al , Cabon Mikael
Published: December 2021

This paper is concerned with an overview of the Resource-Constrained Project Scheduling Problem (RCPSP) and the conventional meta-heuristic solution techniques that have attracted the attention of many researchers in the field. Therefore, researchers have developed algorithms and methods to solve the problem. This paper addresses the single-mode RCPSP where the objective is to optimize and minimize the project duration while the quantities of resources are constrained during the project execution. In this problem, resource constraints and precedence relationships between activities are known to be the most important constraints for project scheduling. In this context, the standard RCPSP is presented. Then, the classifications of the collected papers according to the year of publication and the different meta-heuristic approaches applied are presented. Five weighted articles and their meta-heuristic techniques developed for RCPSP are described in detail and their results are summarized in the corresponding tables. In addition, researchers have developed various conventional meta-heuristic algorithms such as genetic algorithms, particle swarm optimization, ant colony optimization, bee colony optimization, simulated annealing, evolutionary algorithms, and so on. It is stated that genetic algorithms are more popular among researchers than other meta-heuristics. For this reason, the various conventional meta-heuristics and their corresponding articles are also presented to give an overview of the conventional meta-heuristic optimizing techniques. Finally, the challenges of the conventional meta-heuristics are explored, which may be helpful for future studies to apply new suitable techniques to solve the Resource-Constrained Project Scheduling Problem (RCPSP).

Published: December 2021

The worldwide use of nanotechnology in most industries, such as in oil and gas industries, the world now has been directed towards introducing this modern technology in drilling fluids for the purpose of reaching and extracting hydrocarbons that exist at high depth where high temperatures and high pressure present using this technology to achieve the required mud properties with lowest cost.

In this research, the particles of Nano hematite were prepared in laboratory using two methods, the first method by chemical reaction between iron nitrate (Fe (NO3)3• 9H2O) and ammonium hydroxide (NH4OH), after that, prepared Nano-materials were subjected to AFM, XRD testing in order to investigate the size and type of particles, the investigations showed that the formed particles were Fe2O3 (<100nm). The second method is similar to the first method except adding (CTAB) material in order to reduce the interfacial tension leading to 4.5nm Nano-material. Three samples of drilling mud were prepared, the first sample was prepared from water and bentonite only, the second sample was prepared from water, bentonite and nano (prepared from first method), the third samples was prepared from water, bentonite and nano (prepared from second method), rheological properties, filtration, density, lubricity, sagging and magnetism properties were measured by analyzing and comparing the results. The results were obtained showed that the small effect of nano material filtration, density, lubricity, and sagging properties, except the viscosity increase when the second sample of Nano hematite was added to the mud prepared from water and bentonite. Also, the magnetism increase when the second sample of nano hematite was added to the mud prepared from water and bentonite, due to the difference in the molecular arrangement caused by the presence of CTAB.

Authors: Alhammod Wessam Abdul Abbas , Aljizani Ban Talib
Published: December 2021

This research focused on using seismic data to review the structure of the (X) Oil Field, located 40 km SW of Basrah, Southern Iraq. The study utilises a 3D seismic survey conducted during 2011-2012, covering the (Y) Oil Field 2 km to the west, and with partial coverage across (X), to map the Top Zubair reflector. Seismic rock properties analysis was conducted on key (X) Oil Field wells and used to tie the Top Zubair reflector on (X) Oil Field. The reflector was mapped within the time domain using DecisionSpace Software, and then converted to depth using a velocity model. The depth structure map was then compared to the original oil water contact (OOWC) across the fields to understand the potential structural closure of the Top Zubair reservoir in both fields.

The main aim of the study was to distinguish clinical, radiological and morphological features of bone cysts of long tubular bones in children. Methods.156 cases of bone cysts were enrolled in the study: 39 cases of aneurysmal bone cysts (ABC) and 117 – solitary bone cysts (SBC). Specific clinical and radiological findings of bone cysts make it possible to establish the correct diagnosis in most cases. Results. Most of the patients with bone cysts - 118 (81.4%) complained of an aching nature of low-intensity pain in the affected area, arising during or after physical exertion. Solitary bone cysts were a centrally located intramedullary unicameral cystic cavity. Aneurysmal bone cysts were benign, multicameral, blood-containing cystic lesions. Conclusions. Typical clinical and radiological manifestations of bone cysts in most cases make it possible to establish the correct diagnosis. If there is any doubt about the correctness of the diagnosis, open biopsy is performed with excision of the pathological focus within unchanged tissues. Further treatment tactics in such cases is determined after morphological verification of the diagnosis.

In children, the restoration of anatomical structures and functions of the hip joints occurs with early diagnosis and timely initiation of complex treatment. However, in children with hip dysplasia rehabilitation should be early, comprehensive and systematic. At the stages of conservative treatment rehabilitation includes: massage, physiotherapy, therapeutic exercises and most importantly the wearing of functional tires. With the right choice of rehabilitation tactics, the progression of the disease is prevented, as well as early and late complications do not develop, and most importantly, it does not delay the verticalization and does not violate the static-dynamic function of the hip joint.

Published: December 2021

Objective: to study the results of total knee arthroplasty in the presence of tibial bone defect plateau using an original technique of bone autoplasty. Methods. The analysis of the results of treatment of 12 patients (7 women, 5 men). In 7 patients, primary gonarthrosis was diagnosed, in 2 – post-traumatic, in 3 – secondary arthrosis on the background of rheumatoid arthritis (RA). All patients, due to the presence of tibial condyle defects, underwent bone autoplasty using an original technique. The average defect depth was 13.1±5.2 mm (from 7 to 20 mm), width – 14.2±4.3 mm (from 10 to 22 mm). The observation period was 40±24 months (from 28 to 60 months). The average duration of the operation was 115.7±13.2 minutes (from 90 to 127 minutes). Results. Functional assessment according to the Knee Society Scores (KSS) questionnaire: 6 patients obtained excellent results, 4 – good, 2 – satisfactory (patients with RA). No infectious and thromboembolic complications were recorded. According to X-ray data, there were no signs of instability of the endoprosthesis components. No infectious and thromboembolic complications were recorded. According to the X-ray data, no signs of instability of the components of the endoprosthesis were revealed. Conclusions. Bone autoplasty with resected tibial condyles makes it possible to restore defects up to 20 mm deep. The use of autologous bone reduces the likelihood of allergic reactions, increases the chances of a complete restructuring of the graft and restoration of the supporting surface. The original technique of bone autoplasty provides stable fixation of the graft until its consolidation without additional fixation with metal structures.

Untreated injuries to the Achilles tendon can lead to proximal retraction of the muscle-tendon fragment, increasing the likelihood of unsatisfactory results. The use of the long flexor tendon of the first toe is a well-proven method of treatment of this pathology, traditionally performed openly, by dissecting and exposing the soft tissues. We presented a clinical case of a patient with an Achilles tendon injury. In this article, we decided to share with the possibility of performing endoscopic transposition of the long flexor of the first toe in patients at risk of skin complications.

This article presents a clinical case of combined injury of three ligaments (anterior and posterior cruciate and medial lateral ligaments) in a 46-year-old overweight woman (BMI = 38). The late diagnosed damage to the ligaments and the lack of conditions for their normal recovery led to combined instability of the knee joint and the appearance of indications for their reconstruction. At the moment, 6 weeks after the operation, the patient began to step independently on the operated limb, the range of permissible movements in the knee joint was flexion up to 90 degrees. The planned period of full recovery is 24 weeks. Key words: combined knee joint instability, posterior cruciate ligament, medial lateral ligament, anterior cruciate ligament, knee injury, clinical case.
EMR: A new metric to assess the resilience of directional mmWave channels to blockages
Authors: Fatih Erden  , Ozgur Ozdemir  , Ismail Guvenc  , David W. Matolak
Published: December 2021

Millimeter-wave (mmWave) communication systems require narrow beams to compensate for high path loss and to increase the communication range. If an obstacle blocks the dominant communication direction, alternative paths (directions) should be quickly identified to maintain reliable connectivity. In this paper, we introduce a new metric to quantify the Effective Multipath Richness (EMR) of a directional communication channel in the angular domain. In particular, the proposed metric takes into account the strength and spatial diversity of the resolved Multipath Components (MPCs), while also considering the beamwidth of the communication link and the blockage characteristics. The metric is defined as a weighted sum of the number of distinct MPC clusters in the angular domain, where the clustering of the MPCs is performed based on the cosine-distance between the dominant MPCs.

For a given transmitter (TX) and receiver (RX) pair, the EMR is a single scalar value that characterizes the robustness of the communication link against blockages, as it captures the number of unique communication directions that can be utilized. It is also possible to characterize the blockage robustness for the whole environment by evaluating the spatial distribution of the EMR metric considering various different TX/RX locations. Using our proposed metric, one can assess the scattering richness of different environments to achieve a particular service quality. We evaluate the proposed metric using our 28 GHz channel measurements in a library environment for Line-of-Sight (LOS) and NLOS scenarios, and compare it with some other commonly used propagation metrics. We argue that EMR is especially informative at higher frequencies, e.g., mmWave and terahertz (THz), where the propagation attenuation is high, and directional Non-Light-of-Sight (NLOS) communication is critical for the success of the network.
Infrastructure sharing model to connect the unconnected in rural areas
Authors: Ida S�m�vo Tognisse  , Ahmed Dooguy Kora  , Jules Degila
Published: December 2021

One of the major problems the telecommunication industry faces in providing connectivity to the unconnected, particularly in rural and remote areas, is the lack of infrastructure in these areas. Indeed, deploying a network in an isolated area can be more expensive for an operator than in an urban area, while the return on investment is not possible. This is the primary cause of the coverage divide. To remedy this, in this work, we propose a techno-economic analysis of infrastructure sharing. First, we develop a mathematical model of the overall cost of extending a mobile network in rural areas. Different scenarios involving infrastructure sharing at varying levels of deployment are then presented. Then, using the models proposed in each scenario, we make a case study to deduce the most economically advantageous scenario for operators to extend their networks to remote areas. This case involves the sharing of passive infrastructure and also the sharing of active resources in a cloud-RAN. Based on the proposed model, our simulation results show that while passive sharing is beneficial, active sharing using cloud-RAN as technology increases this benefit. This work also indicates and highlights the technical constraints to be respected in the sharing for this scenario.
Doors in the sky: Detection, localization and classification of aerial vehicles using laser mesh
Authors: Wahab Khawaja  , Ender Ozturk  , Ismail Guvenc
Published: December 2021

Stealth technology and Unmanned Aerial Vehicles (UAVs) are expected to dominate current and future aerial warfare. The radar systems at their maximum operating ranges, however, are not always able to detect stealth and small UAVs mainly due to their small radar cross sections and/or low altitudes. In this paper, a novel technique as an alternative to radar technology is proposed. The proposed approach is based on creating a mesh structure of laser beams initiated from aerial platforms towards the ground. The laser mesh acts as a virtual net in the sky. Any aerial vehicle disrupting the path of the laser beams are detected and subsequently localized and tracked. As an additional feature, steering of the beams can be used for increased coverage and improved localization and classification performance. A database of different types of aerial vehicles is created artificially based on Gaussian distributions. The database is used to develop several Machine Learning (ML) models using different algorithms to classify a target. Overall, we demonstrated through simulations that our proposed model achieves simultaneous detection, classification, localization, and tracking of a target.
Game Theory and Dealing with Water Conflict

Published: December 2021

Abstract In the last century, water conflicts have increased in many parts of the world for reasons such as a strong desire for rapid development and poor governance. The impact of these conflicts on various sectors of society such as economic, political and legal subsystems has led researchers to focus on providing solutions and practical methods to deal with water conflicts. Game theory is one of the most common methods used by researchers to manage water conflicts and water allocation in shared and transboundary river basins. Despite the special place of game theory in reductionist sciences, the application of this theory to dealing with conflicts in complex water systems faces challenges. Whereas, the critique of the effectiveness of the game theory method in water conflict management has been neglected. Accordingly, the purpose of this study is to investigate and analyze the capacity to apply the game theory to deal with water conflicts. In order to achieve this purpose, while using library resources, the basics of game theory and the capacity to apply it in the management of water conflicts are analyzed. The results reveal that following the theory of rational choice and rationalism in the game theory method has led to ignore many dimensions and factors affecting the water conflict formation and the way to deal with complex water conflicts. Keywords: Water Conflicts, Game Theory, Peacebuilding, Shared and Transboundary River Basins
Clinical and Epidemiological Description of Headache Attributed to Stroke
Authors: Batista. Laura , Suzart Gabriel
Published: December 2021

Background: The post-stroke persistent headache syndrome is poorly characterized in the literature and recognized in clinical practice. The objective of this study is to describe the clinical and epidemiological profile of patients with persistent post-stroke headache and its pattern. Design and setting: Cross-sectional study at a reference stroke outpatient clinic from Federal University of Bahia. Methods: Patients were actively approached during the usual consultation. Results: From a total of 52 stroke patients, 11 (21.2%) were diagnosed with persistent post-stroke headache, 19 (36.5%) with acute post-stroke headache and 22 (42.3%) without headache. Systemic arterial hypertension was more frequent in the group without headache (95.5%) than in the group with persistent headache (63.6%). On the other hand, the second group presented a greater proportion of sedentary lifestyle (90.9% vs 54.5%) and smoking (45.5% vs 27.3%) than the first group. In patients with persistent headache, the median frequency of pain in the last 3 months was 40.5 days (IIQ 14.25 - 90.0) and the most frequent locations were strictly unilateral (45.5%) and holocranial (36 , 4%), with no individual reporting an alternating unilateral pattern. Conclusions: Corroborating the results of previous studies, our data demonstrated a relevant prevalence of persistent post-stroke headache, and it is possible that previously hypertensive patients are more protected for the development of persistent headache than individuals without hypertension.

Published: December 2021

Background: The literature is scarce in descriptions of post-stroke outcomes related to socioeconomic status. Our objective is to describe the association between stroke outcomes and Human Development Index and to evaluate this relation’s geographical distribution in the city of Salvador, Brazil. Design and Settings: Cross-sectional study at Hospital Geral Roberto Santos. Methods: Georeferencing was made using the 2010 Brazil Census. Mortality, post discharge improvement and functional independence at 90 days after stroke were the outcomes obtained with the modified Rankin Scale. Results: From 382 patients with ischemic stroke, 193 were included because they lived in Salvador and had available address information. Only 01 patient was from a low HDI, 74 (38,3%) medium HDI, 90 (46,6%) high HDI and 28 (14,5%) very high HDI region. These groups had, respectively, 4,3%, 12,1% and 10,8% mortality rate, 56,5%, 53% and 56,9% functional independence rate and 45,4%, 40,3% and 35,7% post discharge improvement rate. Only 87 patients had complete address information to be included in the geographical distribution of these results. The results were proportional to the number of individuals in each HDI region. Conclusion: The only outcome that had a direct relation with HDI is post discharge improvement. Likely, it is the outcome that better reflects the recovery assistance available to the patient with stroke. *Authors contributed equally.

Context: Dermatomyositis is an inflammatory myopathy, which results from loss of tolerance to a select group of autoantigens, with an incidence of approximately 0.8 to 1.2 per 100,000, of bimodal distribution, more frequent in women, with important relationship with paraneoplasia, usually responsive to treatment. Case report: female, 65 years old, black, rural worker, with history of increased skin pigmentation in early 2019. After two months, she was bedridden, with dysphagia. Physical examination revealed paresis, poikiloderma on the face, alopecia, remnants of uper back shawl sign, Heliotrope and Gotron sign. Complementary investigation showed: aldolase 20.4 / 31; CPK: 521/220/207. Anatomopathological examination of skin biopsy reveald superficial and discrete lymphocytic dermatitis with focal pigmentary incontinence; electroneuromyography presented myopathic pattern in the four limbs. Paraneoplastic investigation was negative. There was a response to corticosteroids and metotrexato. Conclusions: The case shows a rapid progression from cutaneous symptoms to chronic symptoms and highlights the importance of recognizing skin lesions in view of the possible differential diagnoses in the neurology specialty, prior to the onset of the classic clinical picture and the appearance of chronic symptoms.
Primary central nervous system angeitis (APSNC) is a vasculitis
Authors: Mantovani Gabriel Paulo , Rodrigues Rodrigo Fellipe , Borelli Wyllians Vendramini
Published: December 2021

Context: Primary central nervous system angeitis (APSNC) is a vasculitis confined to the central nervous system (CNS). Its incidence rate is 2.4 cases per 1,000,000 person-years. It affects predominantly small and medium sized arteries of the cerebral parenchyma, spinal cord and leptomeninges. The most common manifestations are headache, cognitive impairment, stroke and transient ischemic attack. The fact that it results in multifocal inflammation of the arteries and veins can lead to ischemic or hemorrhagic infarctions in multiple vascular territories, more common in the subcortical white matter. Case report: A woman with a past of epilepsy and headache present to us with acute intraparenchymal hemorrhagic stroke, after extensive investigation, arrived at the presumed diagnosis of APSNC. Conclusion:Tests such as MRI and arteriography have low sensitivity and specificity for APSNC and brain biopsy is still the gold standard method for diagnosis, but in practice it is performed in less than half of the cases in clinical practice, this is due to several factors. Next, it is important to note that the biopsy efficiency is around 53-74% in unselected areas, reaching 80% if the site is selected affected by non-invasive exams. The literature specifies brain biopsy as a procedure with relatively low morbidity and mortality, however, it was not performed in more than a half of cases.

Background: Polyneuropathy is the simultaneous dysfunction of several peripheral nerves that normally occurs as a result of diabetes. Objectives: To analyze the current panorama of treatment of polyneuropathies performed in the State of São Paulo and to correlate with the epidemiology. Methods: literature review and observational, descriptive and transversal data collect on treatment of polyneuropathies, available at DATASUS from January 2008 to December 2020, assessing the number of hospitalizations, the amount of public spending, complexity, mortality rate, deaths, permanence and character of service, and articles available in Scielo, Lilacs and PubMed. Results: There were 19,099 hospitalizations for polyneuropathy treatment procedures with a total expense of R$ 21,870,767.84, with 2014 being the year with the highest number of hospitalizations (1,740) and with the highest amount spent (R$ 2,034,880.25) . Of the total procedures, 3,732 were carried out on an elective basis and 15,362 in urgency, with 5,774 in the public sector and 6,396 in the private sector. All 19,099 considered to be of medium complexity. The total mortality rate was 1.63, corresponding to 312 deaths, with 2020 being the year with the highest mortality rate, 2.42, while 2014 had the lowest rate, 1.26. The mortality rate for elective procedures was 0.38 compared to 1.94 for urgent procedures, whereas in the public sector it was 1.25 compared to 1.77 for the private sector. The average total hospital stay was 9.3 days, with an average cost of R$ 1,145.13. Conclusion: Polyneuropathy is a disease that has a low mortality rate.

Background: Chronic subdural hematoma is a common type of intracranial hemorrhage with a greater predominance in the elderly. Objectives: To analyze the current panorama of surgical treatment procedures for chronic subdural hematoma performed in the State of São Paulo and to correlate the current epidemiology with the results obtained. Methods: A literature review and an observational, descriptive and transversal data collect on surgical treatment was carried out, available from January 2008 to December 2020 and articles available in Scielo, Lilacs and PubMed. Results: There were 15,148 hospitalizations for surgical procedures for the treatment of chronic subdural hematoma, representing a total expenditure of R$ 45,365,258.21, with 2018 being the year with the highest number of hospitalizations (1,418) and with the highest amount spent during the period (R$ 4,570,334.28). 678 of them were elective while 11,671 were urgent. 3,820 were carried out in public care and 4,317 in private one. All of them were considered medium complexity. Mortality rate was 9.20, corresponding to 1,393 deaths, with 2020 the year with the greatest mortality, 10.24, and 2013 with the lowest, 8.00. The mortality rate for elective procedures was 10.18 compared to 9.63 for urgent procedures, whereas in the public sector it was 8.09 compared to 9.73 for the private sector. The average total hospital stay was 8.7 days, with an average cost of R$ 2,994.80. Conclusion: There is a greater number of hospitalizations in the urgency and private sector and a higher mortality rate in elective procedures and in the private sector.

Chronic Pain (CP) affects one in five people in developing countries, and is the most frequent reason motivating medical visits. Some CP types rank as the most common symptomatic diseases affecting humans worldwide (eg, tension-type headache), and the most common cause of years lived with disability (eg, low back pain). Despite the high costs related to the diagnosis and management of CP, up to 40% of patients remain symptomatic despite best medical therapy. The relative inefficiency of CP management stems from several causes, lack of good predictors of response to treatment being one of them. Inefficient prognostication leads to low response to treatment, high odds of side-effect and iatrogeny, especially in CP syndromes where lesion to somatic or neural tissues are not the driving mechanisms leading to pain (primary headaches, low-back pain, fibromyalgia). We have developed an electronic medical record system specific for pain management and used it in 611 prospective patients addressed to our Institution. We then used structured and unstructured data from the first visit and used as an end-point of good outcome the two higher strata of the patients’ Global Impression of Change score (very much and much improved) systematically collected at the last visit, which took place within 12 months from the first. By using state of art AI algorithms in an interpretable approach, we obtained a list of 12 highly predictable variables, which included pain in specific pain areas of the body, sex, pain pattern and temporal profile. Using these variables, and their complex relationship, we developed a machine learning model that predicted a good long-term outcome at the moment of the first visit, yielding a sensitivity and specificity of 0.69 and 0.73, respectively, with an area under the curve of 0.71. When imputed with variables from the second visit, AUC numbers reached 0.85. Business Model: given the challenges that health systems around the world are facing, the main target today is to make the shift from a payper-use mode to a value-based approach. This will bring the patient to the center of medical decisions. Chronic pain is an ideal scenario to test new strategies directed to these goals. In fact, our strategy allowed the identification of patients who would not respond to traditional therapeutic approaches before they were implemented, potentially saving time, resources and mitigating suffering. Public health systems and integrated health operators can be greatly benefited using this tool by increasing treatment effectiveness and reducing losses. Lower costs for all enables more people to access good health faster. Market share: large health conglomerates with closed loops of care including diagnostic and health-care provider facilities using electronic data record systems.

Pendidikan merupakan salah satu bentuk perwujudan kebudayaan manusia yang dinamis. Pendidikan hendaknya mempersiapkan siswa di masa yang akan datang sehingga siswa dapat menyelesaikan masalah- masalah yang dihadapi dalam kehidupan sehari-hari. Dengan demikian, siswa dapat melangsungkan kehidupannya dalam hidup bermasyarakat. sekolah merupakan salah satu tempat siswa mendapatkan pendidikan. Kegiatan-kegiatan yang dilaksanakan di sekolah sebagian besar bertujuan untuk mendidik siswa. Belajar dan mengajar merupakan salah satu kegiatan yang dilakukan di sekolah. Menurut Winkel (1983), belajar merupakan suatu aktivitas mental/psikis, yang berlangsung dalam interaksi aktif dengan lingkungan, yang menghasilkan perubahan-perubahan dalam pengetahuan-pemahaman, keterampilan dan nilai-sikap. Perubahan itu bersifat secara relatif konstan dan berbekas. Dengan demikian, peserta didik dikatakan belajar apabila peserta didik melakukan kegiatan interaksi aktif dengan lingkungan sehingga memperoleh pengetahuan, keterampilan, serta nilai sikap. Mengajar adalah untuk melihat bagaimana proses belajar berjalan. Tidak hanya sekedar mengatakan dan memberikan instruksi atau tidak hanya membiarkan siswa belajar sendiri.

Subjek penelitian adalah siswa kelas X SMAN 17 Makassar yang terdiri dari 2 orang pada masing-masing tingkat kemampuan siswa. 2 siswa prestasi belajar tinggi (PBT), 2 orang siswa prestasi belajar sedang (PBS), dan 2 orang siswa prestasi belajar rendah (PBR). Kemampuan memecahkan masalah merupakan salah satu tujuan dari pembelajaran matematika yang meliputi kemampuan memahami masalah, membuat rencana, melaksanakan  rencana, dan memeriksa kembali. Dalam memecahkan suatu masalah perlu di perhatikan tahapan dan proses penyelesaiannya dengan baik. Pengumpulan data dilakukan dengan cara analisis tugas dan wawancara. Hasil penelitian menunjukkan dalam 3 kelompok tersebut terdapat warna berbeda yang bisa diperoleh dari keragaman komunikasi dalam pemecahan masalah matematika dengan memperhatikan kemampuan komunikasi dengan simbol visual-verbal matematis. Siswa dengan prestasi belajar tinggi cenderung memiliki  kemampuan komunikasi visual dan verbal matematis yang lebih kompleks dibanding siswa dengan prestasi belajar sedang dalam memecahkan masalah matematika. Sedangkan, siswa dengan prestasi belajar rendah cenderung memecahkan masalah dengan komunikasi simbol verbal matematis.
