The aim of this study is to examine the problem-solving processes and problem-posing skills of pre-service mathematics teachers, which consists of four stages (understanding the problem, preparing a plan for the solution, applying the plan, evaluating) defined by Polya (1997) with the progressive scoring scale based on the alternative assessment approach. Qualitative research approach has been adopted in the study. Participants of the study consist of 71 pre-service teachers studying at the department of primary education mathematics teaching at the education faculty of a state university in the Southeastern Anatolia region of Turkey. Since the problem solving and problem posing behaviors of the participants were examined separately in the study, the gradual scoring scale developed by Baki (2008) was used. As a result of the analysis, it was determined that the participants showed the highest performance in the category of understanding the problem, and the lowest performance in the category of evaluation and problem posing. It was determined that participants who failed in the problem posing phase either wrote the same problem or could not write a problem. Another result reached in the study is that the participants had difficulties in expressing the operations in mathematical language.

[English]: The purpose of this study is to explore the mathematization underpinnings of prospective mathematics teacher’s on mathematics problem solving. This study used explorative research with a qualitative approach. The instruments used in this study were mathematical ability test, contextual problems, and interview guidelines. A prospective mathematics teacher who has high mathematics ability involved in this study.The subject was selected from 56 prospective mathematics teachers through a test. After the subject solved contextual problems, an interview was conducted. The result revealed that the prospective mathematics teacher did mathematization when  solving the contextual problem by simplifying, solving in a structural way, and fitting to the context of the problem. This finding implies that mathematizationc ould reveal the way prospective mathematics teacher formulates contextual problems into mathematical problems.

<em>This research is meant to explain the problem solving efford which is found in academic supervision toward teachers of Mathematics in some guided schools, explains the problem solving steps by the supervisor in guided schools, and shows the teaching quality improvement by the Mathematics teachers in those guded schools. This research was done to some guded schools where ten Mathematics teachers of Senior High Schools or Vocational High School in Kulon Progo District are the subject. The strategy for improving the quality of Mathematics teaching application is through treatment of companion teaching in active sharing knowledge for instance through planning, the step of treatment in the teaching, teaching procedures and class management. The result of acompaniying the teachers of Mathematics shows that Mathematics teachers in Kulon Progo Distric still need some guidance from the supervisors especially in term of innovative teaching process, where most teachers lack of motivation, the Active Sharing Knowledge method can improve the activism of the teachers through out the whole teaching activities, improve the quality of teaching process, students’ activism, concept mastery and teacher’s skills in teaching process as can be seen as followed: the teaching quality of Mathematics teachers using Active Sharing Knowledge is 5%, student’s participations is 46%, while teachers’ mastery of the concept is 14%, and positive reflection as a result of Mathematics Teachers guided teaching implementation using Active Sharing Knowledge where 84% stated agree and totally agree.</em>

Module Development

In the early semester, every study program at faculty of economy required the student to take the introduction of accounting lectures. After taking the lecture the students are expected to be able to comprehend the basic concepts of accounting well. The financial reports material became one of the difficult material in the accounting lecture. Generally, the difficulty could be seen when the students were asked to shift the data from the worksheet to financial reports. It was because the students came from the different high school background. Therefore, it could be affect toward their comprehension of accounting.  Because. Of that reason it was important to develop the material in form of module based problem solving, which can be used to help the students learn how to solve the problem that appears in their experience. This research was aimed to produce the valid module based problem solving.It used 4D module (four-D models). The development of four D consists of 4 phases. They are: 1) Define; 2) Design; 3) Develop; 4) Dessiminate. This development was only untill development phase while dessiminate phasewas not done. The subject of module based problem solving at introduction of accounting lectureswas the first year student of faculty of economy Medan state university. The criterion of the subject eksperimental was the condition of the student which was suitable with the researchers'need. The students haven't used the module based problem solving at the introduction of accounting lecture which is valid, practical, and effective. The module was valid to use because the result of the module validity development achieved 82.29% achievement level, and the module practicality achievement was 81.57%, and it could be categorized practical in learning process. The level of students activity achievement from four categories that was researched in learning process was 63.95%. It could be categorized as active students and module was categorized as an effective module. Therefore, the introductory accounting module based problem solving can be applied in learning process.

Bovine respiratory diseases cause serious economic loses and present diagnostic difficulties due to the variety of etiologic agents, predisposing conditions, parasites, viruses, bacteria and mycoplasma, and may be multiple or complicated. Several agents which have been isolated from the abnormal lungs are still the subject of controversy and uncertainty. These include adenoviruses, rhinoviruses, syncytial viruses, herpesviruses, picornaviruses, mycoplasma, chlamydiae and Haemophilus somnus.Previously, we have studied four typical cases of bovine pneumonia obtained from the Michigan State University Veterinary Diagnostic Laboratory to elucidate this complex syndrome by electron microscopy. More recently, additional cases examined reveal electron opaque immune deposits which were demonstrable on the alveolar capillary walls, laminae of alveolar capillaries, subenthothelium and interstitium in four out of 10 cases. In other tissue collected, unlike other previous studies, bacterial organisms have been found in association with acute suppurative bronchopneumonia.

Patients withdiabetes mellitus (DM) continues to grow because prosperity and people's lifestyles.Treatment of diabetes often usei njections of insulin and oral antidiabetic drugs. Thetreatment has no side effects. Therefore, it is necessary to find effective drugs using plants thatred betel leaf (Piper crocatum Ruiz & Pav.). Red betel leaf contains flavonoids which are antioxidants. This study aims to determine the effect and dose of extract of red betel leaf (Piper crocatum Ruiz & Pav.) The most effective agains blood glucose in mice(Mus musculusL.) male induced sucrose.This study was an experimental study. The research was conducted in October 2015 in the Division of Laboratory Animal and Zoology Department of Biology, State University of Padang. The subject of research in the form of mice (Mus musculus L.) males totaled 24 tails. The design used was completely randomized design (CRD) with 6 treatments and 4 repetitions. The treatment is given as follows: treatment I: the diabetes control without any treatment given, treatment II: as a negative control (sucrose 3 g/kg bw), treatment III: sucrose+suspension of red betel leaf extract (dosage 0,7 g/kg bw), treatment IV: sucrose+suspension of red betel leaf extract (dosage 1,4 g/kg bw), treatment V: sucrose+suspension of red betel leaf extract (dosage of 2,1 g/kg bw) and treatment VI: sucrose+suspension extracts red betel leaf (dosage 2,8 g/kg bw).The results showed that the extract of red betel leaf (Piper crocatum Ruiz & Pav.) at a dose of 0,8 g/kg bw 1,4 g/kg bw 2,1 g/kg bw and 2,8 g/kg bw can lowers blood glucose in mice. However, the most appropriate dose in lowering blood glucose in mice (Mus musculus L.) at 2,8 g/kg bw in mice.
