The Impact

The study aims to describe and identify aspects during the thesis writing process. This study uses a qualitative approach with the type of case study research on alumni of the Library and Information Science Study Program Universitas Brawijaya. Then the selection of alumni as informants considers the impact after writing the thesis is completed. The results showed that the reflection of alumni there is a learning process in each stage of thesis writing. The learning process that occurs is quite complex because it is not only done independently but also involves other parties. Independent learning focuses on the process of applying information literacy skills possessed by alumni. Where there is an information management process which is the most important part, because the process affects the decision making for each action. Meanwhile, the involvement of other parties is another role of the thesis as a forum for collaborative learning. Not only that, the whole process forms a new understanding that can be useful across generations.Keywords: Thesis, Reflection, Information Literacy, Knowledge Sharing Practice, Collaborative LearningABSTRAKRefleksi pengalaman alumni merupakan kajian yang bertujuan untuk mendeskripsikan dan mengidentifikasi aspek-aspek selama proses penulisan skripsi.

In this study we examined the problem-solving characteristics, strategy selection and use, and verification actions of 24 African American 8th-grade students. Students participated in individual, talk-aloud problem-solving sessions and were interviewed about their problem solutions and attitudes about learning mathematics. Students displayed approaches attributed to African American learners in the literature, regularly using holistic rather than analytic reasoning; their display of confidence and high self-esteem did not appear to be related to success. Students' problem-solving actions matched previously reported characteristics of good mathematical problem solvers: successful use of strategies, flexibility in approach, use of verification actions, and ability to deal with irrelevant detail. Success was highly correlated with strategy selection and use and moderately correlated with verification actions.

Computational Processes

In an elementary school classroom, as in real life, the lines between the content areas should be blurred, particularly between mathematical problem solving and mathematical situations contextualized in good literature. For that reason, I always look for interesting books about mathematical situations. Why use children's literature to teach mathematics? A good story often places mathematical problems in the context of familiar situations and is similar to, yet a much more elaborate version of, mathematical word problems. Assertions that children's inability to solve word problems results from their inability to read or to compute effectively simply are not true. The problem is that children do not know how to choose the correct operation or sequence of operations to solve the problem. To solve a problem situation presented in words, children need to be able to connect computational processes with appropriate calculations. Their difficulties lie in the fact that children simply do not understand the mathematics well enough conceptually to make the connection with the problem- solving situation. Using books with authentic problem situations may help children see that learning computation serves a real-life purpose.

The article discusses the integrated process of learning mathematics at secondary school. The content of teaching mathematics must be arranged in such a way that the student develops an overall understanding of the world. The aim of the article is to emphasize the depth of comprehension of the content of the subject of the student’s interest, because based on the understanding of the content of the subject, new knowledge will be integrated and new skills will be developed that the student will be able to transfer to other subjects by solving problem situations. The topicality of the article is related to the integration approach, that the main focus is not to focus on the content of the subjects of mathematics and physics, but on the scientific processes that unite the contents of these subjects. Theoretical basis of the research is the system theory, which is based on the approach of learning cognition and constructivism. In the research, students' complex tests and questionnaires with open questions were used for data acquisition. The article uses a case study design to analyse data.

This article reports on the result of a study aiming to describe what difficulties experienced by Batak English learner in consonant sound production and the factors which cause him difficult to produce those sounds. The study was conducted to Batak English learner who is still taking pronunciation course in the first semester in the English study program at one of private universities in East Java, Indonesia. The study used a qualitative case study research design with the data collected from the analysis of students’ English consonants production and interview. The findings showed that all sounds of voiceless dental frecative consonant [θ] in initial position were pronounced into voiceless alveolar stop consonant [t] while the research participant was pronouncing the sound of voiced dental frecative consonant [ð], he mispronounced the sound into voiced alveolar stop consonant [d] in both initial and medial position. The sound of voiced alveolar affricate consonants [dʒ] was pronounced appropriately while voiceless alveolar affricate consonant was pronounced into voiceless alveolar fricative consonant [s]. The factors which cause the participant find it difficult to learn pronunciation were afraid of making mistakes, limited time to repeat it at home, and habit.

Mathematics has an important role in the cognitive development of deaf students. Through learning mathematics in schools, deaf students will explore and build knowledge, because literally mathematics is the parent of knowledge and human activities. One important aspect in learning mathematics is the ability to solve problems. Problem solving means engaging in a task for which the solution method is not known in advance. In order to find a solution, students must draw on their knowledge, and through this process, they will often develop new mathematical understandings.This study aims to analyze the mental act of deaf students in solving mathematical problems in fraction material. Respondents of 20 students were randomly selected from 3 special schools. This type of research is qualitative with a case study design. Data was collected through the instrument of problem solving abilities, interviews, and observations. Data were analyzed using grouded theory. The results of this study indicate that the mental act used by deaf students in solving mathematical problems is interpreting, explaining, inferring, and problem solving.

Background. Student reasoning in learning mathematics contributes significantly to the achievement of student mathematics learning outcomes. The main objective of this study is to investigate the process of reversible reasoning in students for inverse problems, in the case of Adjie (Ad). The research method used to reveal the reversible reasoning in Adjie's case using descriptive qualitative research methods. Sampling was carried out using purposive sampling technique where the research sample was selected based on reversible reasoning criteria. Retrieval research data uses the results of students' mathematical work, think aloud, interviews, and the components that cause reversible reasoning. The results of our study found that the process begins with an obstacle that causes Ad to be unable to continue the resolution process, resulting in a metacognition process by analyzing the problem again analytically and developing other heuristic strategies. Ad shows a change in perspective where he initially interpreted inverse as the act of swapping independent and dependent variables and switched to interpreting inverse as the opposite of a function process involving analogy and image representation. The contribution of this research provides knowledge that reversible reasoning can occur in understanding and solving mathematical problems in inverse material.
