“…Again, for some pre-service mathematics teachers to provide numerical responses to word problems that demanded words or a sentence confirms that trainee's misconceptions in operations on integers is rooted on the problem of language acquisition as Makonye and Fakude (2016), opined that major factor serving as an obstacle for students' poor performance in directed numbers is poor command of students over the English Language. Majority of the pre-service mathematics teachers who could not read, understand and solve the word problems relied on guess as stated (Tiwari & Fatima, 2019). Fadillah and Susiaty (2019) claim that some students made mistakes in interpreting the word problems is confirmed.…”

“…Students' misconceptions were neither inborn nor instantaneous instead, students picked up certain views in the course of their process of learning for unknown reasons. Whatever the source, a way to recognize and resolve the problem should be available (Tiwari & Fatima, 2019).…”

“…Fadillah and Susiaty (2019) asserts that integer operation is an important concept in mathematics learning in lower secondary school yet, many students still have misconceptions in doing integer operations. According to Tiwari and Fatima (2019), some errors are persistent, so that they will occur due to misconceptions which are open to analysis, rather than the random errors that merely occur due to human fallibility. Therefore, examining deep into student thinking and their beliefs is necessary to find reasons for them to make these misconceptions.…”

Purpose: This study investigated common errors and misconceptions made by some pre-service mathematics teachers of the St. Louis College of Education in Ghana about operations on integers. Errors associated with the misconceptions were also explored. Methodology: The study employed mixed-method and sequential explanatory design, Diagnostic test instruments were designed and administered to sixty (60) pre-service mathematics teachers who offer specialized programmes in early grade (EG) and upper primary (UP). Findings: The study identified common errors made by pre-service mathematics teachers as interpretation of the inequality symbols and , addition and subtraction of integers, multiplication and division of integers, problem-solving (word problems). The study also found introduction concept of operations on integers, interpretation of absolute value of integers, problems involving change in the order of operation of integers as common errors made by pre-service mathematics teachers. Furthermore, the study found problems involving more than one operation, over-reliance on calculator usage and rote-learning, and inability to formulate word problems as mathematics problem. Conclusion: The study conclude that deficiency in the language was the course of their inability to solve word problems. Recommendations: The study recommends that when solving word problems involving integers, pre-service mathematics teachers should take read over the problem thoroughly to understand the problem properly. Also, during teaching and learning of mathematics, particularly operations on integers, much attention must be given to helping learners to translate normal language into mathematics language to overcome language deficiency. The study suggest that similar study could be done in other Colleges of Education and institutions to expound the findings.

“…Several studies have been conducted regarding students' understanding and difficulties in algebra (Asquith et al, 2007;Brizuela et al, 2015;Samo, 2009;Tiwari & Fatima, 2019). Algebra as an initial gateway to further learning (Chimoni et al, 2018;Ferrucci, 2004) has provided coherence at all school levels that algebra is an important topic in mathematics.…”

Huruf-huruf aljabar biasanya hanya dikenal sebagai variabel oleh siswa, padahal huruf-huruf aljabar ini memiliki ragam makna pada suatu permasalahan matematis. Pada penelitian ini bertujuan untuk menyelidiki interpretasi siswa terhadap makna dari huruf-huruf aljabar dalam menyelesaikan masalah matematis dengan perspektif siswa dalam masa transisi berpikir aritmetik ke berpikir aljabar. Penelitian yang digunakan pada penelitian kualitatif dengan jenis penelitian pada penelitian fenomenologi. Partisipan penelitian ini merupakan 18 siswa SMP yang diambil dari tiga sekolah yang terdapat di Riau. Teknik pengumpul data pada penelitian ini adalah dokumen lembar kerja siswa, wawancara yang direkam secara audio dan video dan catatan lapangan penelitian. Berdasarkan temuan penelitian pada siswa kelas VII tersebut, ditemukan bahwa siswa menginterpretasikan huruf-huruf aljabar hanya sebagai pengganti dari bilangan tertentu. Siswa menjadikan huruf-huruf aljabar sebatas pengganti bilangan asli dibandingkan sebagai bilangan yang diperumum. Huruf-huruf aljabar yang dikaitkan dengan ekspresi aljabar dan operasi aljabar serta persamaan aljabar memberikan kesulitan bagi siswa dalam menyelesaikan masalah tersebut. Hal ini disebabkan siswa belum mampu melihat bahwa huruf-huruf aljabar tersebut merupakan serangkaian konsep dasar aljabar generalized numbers bahkan pada konsep variabel. Algebraic letters are usually only known as variables by students, even though these algebraic letters have a variety of meanings in a mathematical problem. This study aims to investigate students' interpretation of the meaning of algebraic letters in solving mathematical problems from the perspective of students in the transition period from arithmetic to algebraic thinking. The type of research used in qualitative research is phenomenological research. The participants of this study were 18 junior high school students taken from three schools in Riau. Data collection techniques in this study were student worksheet documents, audio- and video-recorded interviews, and research field notes. Based on the research findings on the seventh-grade students, it was found that students interpret algebraic letters only as a substitute for certain numbers. Students make algebraic letters as a substitute for natural numbers rather than as generalized numbers. Algebraic letters associated with algebraic expressions, algebraic operations, and algebraic equations deliver difficulties for students in solving these problems. This is because students have not been able to see that these algebraic letters are a series of basic concepts of generalized numbers in algebra, even on the concept of variables.

“…Arteriovenous malformations (AVMs) are usually congenital abnormal connec- tions between arteries and veins. AVMs in the mandible and neck region are rare and potentially life-threatening conditions because of possible massive bleeding [1] [2]. Due to its uncertain clinical and radiographic presentations, AVM is first diagnosed usually by a dentist as bleeding.…”

Background: Arteriovenous malformations (AVM) in mandible and neck are potentially life-threatening conditions because of possible massive hemorrhage. They are often first diagnosed by dentists as bleeding. In this case, we report how a tooth extraction turned to a catastrophic condition in a patient with multiple AVMs in the mandibular, submandibular and hyoid region. Case: A 19-year-old male patient diagnosed with AVMs in the mandibular and submandibular regions was admitted to our hospital with the complaint of leaky hemorrhage around the lower left 3 rd molar tooth. Tooth extraction was planned after embolization procedure. The patient was intubated uneventfully using video laryngoscope. However, an acute bleeding of more than 1600 ml occurred in one minute just after the mouth opener was inserted. The patient was transferred to the Interventional Radiology and other branches of the high-flow AVM were embolized. The patient was taken back to the operating room and the tooth was extracted uneventfully. Conclusion: In AVM cases, trauma should be minimized during induction of general anesthesia and intubation should be performed gently with fiberoptic bronchoscopy or video laryngoscopy. We conclude that a multidisciplinary approach as applied to our patient would be valuable in such cases.
