Exploration of Student Thinking Process in Proving Mathematical Statements

A mathematical statement is not a theorem until it has been carefully derived from previously proven axioms, definitions and theorems. The proof of a theorem is a logical argument that is given deductively and is often interpreted as a justification for statements as well as a fundamental part of the mathematical thinking process. Studying the proof can help decide if and why our answers are logical, develop the habit of arguing, and make investigating an integral part of any problem solving. However, not a few students have difficulty learning it. So it is necessary to explore the student's thought process in proving a statement through questions, answer sheets, and interviews. The ability to prove is explored through 4 (four) proof schemes, namely Scheme of Complete Proof, Scheme of Incomplete Proof, Scheme of unrelated proof, and Scheme of Proof is immature. The results obtained indicate that the ability to prove is influenced by understanding and the ability to see that new theorems are built on previous definitions, properties and theorems; and how to present proof and how students engage with proof. Suggestions in this research are to change the way proof is presented, and to change the way students are involved in proof; improve understanding through routine proving new mathematical statements; and developing course designs that can turn proving activities into routine activities.

Exam Answer Detection using Proposed Nested Loop Pixel Checking Based on Image Processing

Tracking object is one of the most discussed problems in digital images processing. The objectives of tracking objects include the counting, correction, classification and so on. This study discusses how tracking objects, in this case the multiple choice chosen by students, is carried out on the exam answer sheet using the proposed nested loop pixel checking method. The answer sheet used here is the answer sheet for the exam from SMK Khoiriyah Hasyim Tebuireng Jombang because each school has a different exam answer sheet format so that the coordinate parameters of each answer sheet between schools must be different. Before the nested loop pixel checking method, preprocessing was carried out first after taking the image, namely cropping the Region of Interest (ROI), conversion to grayscale, filtering, and edge detection using the adaptive Canny edge detection method. The process of nested loop pixel checking is done by iterating successively with steps per answer option, per number of answers, and per column (10 numbers). In addition, a special case is given to find out whether this proposed method works as desired. The results show that this method can track answers for both normal and special cases.

Impact of Virtual Reality in Arterial Anatomy Detection and Surgical Planning in Patients with Unruptured Anterior Communicating Artery Aneurysms.

Anterior-communicating artery (ACoA) aneurysms have diverse configurations and anatomical variations. The evaluation and operative treatment of these aneurysms necessitates a perfect surgical strategy based on review of three-dimensional (3D) angioarchitecture using several radiologic imaging methods. We analyzed the influence of 3D virtual reality (VR) reconstructions versus conventional computed tomography angiography (CTA) scans on the identification of vascular anatomy and on surgical planning in patients with unruptured ACoA aneurysms. Medical files were retrospectively analyzed regarding patient- and disease-related data. Preoperative CTA scans were retrospectively reconstructed to 3D-VR images and visualized via VR software to detect the characteristics of unruptured ACoA aneurysms. A questionnaire was used to evaluate the influence of VR on the identification of aneurysm morphology and relevant arterial anatomy and on surgical strategy. Twenty-six patients were included and 520 answer sheets were evaluated. The 3D-VR modality significantly influenced detection of the aneurysm-related vascular structure (p = 0.0001), the recommended head positioning (p = 0.005), and the surgical approach (p = 0.001) in the planning of microsurgical clipping. Thus, reconstruction of conventional preoperative CTA scans into 3D images and the spatial presentation in VR models enabled greater understanding of the anatomy and pathology, provided realistic haptic feedback for aneurysm surgery, and influenced operation planning and strategy.

Abilities of Physics Education Students in Constructing Graphics Based on Practicum Results and in Interpreting It

The skills to construct and interpret graphs are a form of science skills and are an important component in learning physics.

HERO WITH ZEROES?: Tensions of Using an Anti-Discrimination Framework and an Impact Case Approach for Disability Rights Advocacy in China

In 2014, a blind massage therapist named Li Jinsheng took the National College Entrance Examination (NCEE) in Braille, the first to do so in China. To everyone's surprise, he turned in blank answer sheets for two of the four subjects, which generated strong criticisms from the general public and blind communities. This article examines the conditions, process, and aftermaths of this event to consider what it means to use an anti-discrimination framework and an impact case approach for disability rights advocacy. Data comes from observation of media representations and discussions, interviews with key actors and stakeholders, and a focus group with blind college students.Our analysis of Li's case shows that in China, anti-discrimination actions often take the form of using individual cases to attack single, identifiable policy barriers, and they are typically carried out by people who are not directly impacted by the state's paternalistic biobureaucracy or the vulnerabilities it generates. As such, these cases might not sufficiently represent the desires and struggles of most people with disabilities, and the individualistic approach might further alienate the disabled communities. While effective in dismantling the particular policy barrier, such anti-discrimination actions may fall short of addressing more systemic, structural issues. This article ends with reflections on the tensions in using anti-discrimination impact cases in China and beyond, and on how to work on deeper struggles and build broader alliances in disability rights advocacy.

INVESTIGATING THE INDONESIAN EFL STUDENTS’ ARGUMENT IN ARGUMENTATIVE ESSAY

This study investigates the written test results of the Indonesian undergraduate students’ argumentative essay. For that reason, three research questions are made. 1). what is the level of achievement of the students in the argumentative essay quantitatively? 2). what aspects of an essay appear in respect to the argumentative essay generic structure as formulated? 3). how well did they use the rhetoric reputation and argument in their essay?. 27 handwriting' answer sheets of undergraduate English Department students enrolled at semester four of a state university in Indonesia were taken purposively. The data analysis uses a quantitative and qualitative approach. The results show that the students quantitatively achieved average score 76,74 which means good. All parts of generic structures were expressed in different quality. However; the organization of the essay is the lowest part compared to the other four parts respectively content, vocabulary, and language use seen from their segmented scores. This study is confirmed to be inline the previous study in that the majority of the students did not present the refutation section in both their English essays. This implies that teachers should be more aware of promoting this absent aspect as this refutation or rebuttal is a distinguishing marker in argumentative and discussion essays.

Students’ thinking: arithmetic in solving a mathematical problem

The students in secondary school have difficulties making the transition from arithmetic to algebra. In order to obtain the students approach while solving the problem, the students are given a mathematical problem that can be solved by using arithmetic or algebraic. This study is implemented in class grade 7, and they have learnt the introduction of algebra. This research was using a qualitative method with description design. Six students who are a participant in this study have excellent communication and give different strategies while solving the problems. The students are given a mathematical test problem, and then the students are interviewed based on their answer sheet in the test in order to get in-depth information from their strategies. From the result of students are given, we acquire that the arithmetical approach is dominated in their strategy to solve the problem. Many of the students do not realize the using of the quantities of the unknown in that problem. Arithmetic is the approach that accomplished to coverage the students to solve the problem and the students just do numbers and operation, and focus in numeric answer. Most of the student in a secondary school in seventh grade is direct think arithmetically than algebraically.
