<![CDATA[Teachers are still considered the only centers of learning in mathematics, in the sense that only teachers in the delivery of materials that play an active role in the classroom, so that the learning process becomes ineffective. It can be to affect the low studentsâ result. Efforts are being made to overcome this is to involve students actively and creatively in the process of formation of knowledge. The Piagetâs theory of constructivism assimilation and accommodation is a learning that allows students to be active and critical in the process of learning and allow students to construct their own knowledge based on experience and knowledge they have. The population was all of the students in eight grade of SMP 25 Bandar Lampung in the academic year of 2013-2014. The samples of the research were taken by using the cluster random sampling technique. To obtain data through the studentsâ result in the form of an essay test consists of 5 items, then the data were analyzed using t-test. Based on hypothesis test, it can be included that, there is influence the Piagetâs theory of constructivism assimilation and accommodation to the improvement of knowledge formation about circle.Keywords: The Learning Assimilation and Accomodation, The Piagetâs Theory of Constructivism, The Knowledge Formation About Circle]]>

<![CDATA[Learning Mathematics in SMP Muhammadiyah Pringsewu tends to be teacher-centered learning process. Teacher as the main source of learning, students is less involved in discovering the science of Mathematics, the result of studentsâ achievement is low. From that condition it is very crucial to apply the alternative learning using cooperative model type problem solving. The aims of research are to know the differences of average score between students in control and experimental class and to know which one is higher of mathematicsâ score between students in control and experiment class. The population of research is the students at eighth grade in even semester in SMP Muhammadiyah Pringsewu in the academic year of 2012/2013. The sample of research used cluster random sampling technique. The result of learning process is from test with 5 items of essay. The analysis of data using test of normality, test of homogeneity, those are as pre-requisite test before conducting t-test. From the result of data analysis, the average score of Mathematics in experiment class is 67.74 and control class is 58.21. The conclusions are; there is a significant difference between the average scores of Mathematics in experiment and control class.

<![CDATA[Abstract The blind students have limitations in receiving information, they are only a hold of the senses of hearing and touch, so understanding of abstract mathematical objects understood through verbal description of teacher with concrete objects directly fingered. This can result in a lack of ability of students to accept the concepts being. The acceptance of blind students in understanding the concept of geometry, include: 1) the students attention to the teachers explanation; 2) the pattern of asking; and 3) the pattern of answers. Reception pattern blind students in understanding the concepts learned can be viewed through direct observation during the learning activities with the help of a data recording device handycame. The data has been analyzed through the stages of data reduction, data presentation and conclusion and validity of the data obtained by using triangulation time. The result showed that blind students have a pattern of acceptance in understanding the concept of geometry, as follows: 1) the students attention to the explanation of the teacher in the learning merely listened without linking with the previous concept; 2) the pattern command asks merely asking the teacher is less clear, which is not directly related to the concept studied; 3) the pattern of students in answering questions of teachers, obtained from the statements that have been previously informed. Keywords:reception pattern, blind students, mathematics learning]]>
