#### Abstract

The purpose of this study was to identify problem posed by prospective teachers about addition fractions based on meaning structure. This study is a quantitative descriptive to identify errors of fraction problem posed by prospective teachers based on the meaning.  46 prospective primary teachers in 8th semester in universities at Surabaya were involved in this research. Instrument in this study is a problem posing worksheet consisting two operations on fractions. Problems posed by prospective teachers were analyzed through three stages, grouping problems based on categories, structure of meaning, and analyze the error of the problem posed. The results of data analysis indicated that: (1) on the category of questions about fractions of 93.48% for 1stoperations and 97.83% for 2ndoperation, (2) on the Non-question category about operations fraction is 6.52% for 1st operations and 1.17% for 2nd operation. Grouping problems posed by prospective teachers based on structure meaning combined category is 62.79% for 1st operations and 75.56% for 2nd operation. For category of part relationships overall is 27.91% for 1st operations and 20% for 2ndoperation, while those which not belonging to the second category are 9.3% for 1st operations and 4.44% for 2nd operation. The errors of problem posed by prospective teacher based on meaning structure are (1) not related to daily life situation, (2) illogical problem, (3) unit is not appropriate, (4) fractions incompatible with the sum operation (5) gives whole number to give meaning fraction, (6) lost information, and (7) the added result exceeds the overall concept of the fraction.

#### Abstract

Abstract: The activity of finding answers to mathematics problems is not easy. Most of MTs Attaraqqie Malangâs students have difficulties when solve PtLSV problems. Students canât transform narrative texts to mathematics sentence so that they are hard to find the right answer. Therefore, the researchers do a study that aims to describe the form of student difficulties in solving PtLSV problems and the implementation of scaffolding. This research is a qualitative-descriptive research. The research was conducted in MTs Attaraqqie Malang which was attended by 28 students of class VII. The PtLSV problem is given as many as three items. Three research subjects were selected from diagnostic tests, interviews, and mathematics teacher suggestions. The results showed that students: (1) difficulty of understanding the problem (canât write down the information that was known and asked the question correctly) so assisted by scaffolding level 2 explaining and reviewing; (2) difficulty of devising a plan (can not determine the initial step and the right concept in solving the problem) and assisted by scaffolding level 1 environmental provision and level 2 reviewing; (3) difficulty of carrying out the plan (unable writing mathematical model according to the problem, not using the correct concept, and can not do systematic calculation so that the final result obtained is wrong) and assisted by scaffolding level 2 that is reviewing and restructuring and level 3 is developing conceptual thinking; (4) difficulty of looking back (not checking the truth of answers and difficult to interpreting answers) and assisted by scaffolding level 2 reviewing and level 3 developing conceptual thinking.Abstrak: Kegiatan menemukan jawaban dari permasalahan matematika tidaklah mudah. Sebagian besar siswa MTs Attaraqqie Malang kesulitan ketika menyelesaikan masalah PtLSV. Siswa tidak dapat mengubah teks naratif ke bentuk kalimat matematika sehingga mereka kesulitan untuk menemukan jawaban benar. Oleh sebab itu, peneliti melakukan penelitian yang bertujuan untuk mendeskripsikan bentuk kesulitan siswa dalam menyelesaikan masalah PtLSV dan pelaksanaan scaffoldingnya. Penelitian ini adalah penelitian kualitatif-deskriptif. Penelitian dilaksanakan di MTs Attaraqqie Malang yang diikuti oleh 28 siswa kelas VII. Masalah PtLSV diberikan sebanyak tiga item.

#### Abstract

Evidence is an absolute feature of mathematics and a key component in mathematics education. Although the evidence is very important, the fact is that the evidence is something that is difficult to teach or learn. One of the difficulty factors is the inadequacy of conceptual concepts and the inability to use definitions to structure evidentiary structures. This paper will describe the thinking process of students in proving a geometric proposition. Four concept of image conceptualization framework is used as a tool to explore students' thinking processes in proving a geometric proposition. One student's work and vignette, FMZ, was analyzed to provide a visualization of the image-conceptualization process used by FMZ in identifying a proposition. The results of the analysis confirm that the ability to construct evidence is related to the ability to conceptualize images, find local-local conceptualizations (traits / conclusions related to one part of the image) and global conceptualization and link relational relationships between local conceptualizations and global conceptualization into a series of statements supporting propositions / conclusion which will be proven to be a series of logical statements.
