Get PDFThe purpose of this study is to describe the level of statistical reasoning of male students in statistical problems, and describe the level of statistical reasoning of female students in statistical problems. The method used in this study is descriptive qualitative which describes the level of statistical reasoning of male and female students in statistical problems solving. The results of his research are there are differences in the level of statistical reasoning of male and female students in solving statistical problems. There are differences in the level of statistical reasoning between male and female students in the statistical reasoning process. Differences in the level of statistical reasoning between male and female students in the process of analyzing and interpreting data. Male students at level 4 and female students at level 5, whereas in the process of describing data, organizing data and replicating data on male and female students are at the same level. In describing data on male and female students at level 4, in the organizing process data on male and female students at level 3, in the process of representing data on male and female students at level 5
Guided Discovery Worksheet for Increasing Mathematical Creative Thinking and Self-Efficacy
Get PDFThis research development aimed to develop of worksheet based on guided discovery for increasing mathematical creative thinking and student’s self-efficacy. Development stage in this study is a preliminary study, planning, development of worksheet, worksheet validation, and field testing. The subject of this research is the students of class 10A3 and 10A5 MAN 1 Central Lampung in the Academic of 2017/2018. The data of this research were obtained by observation, interview, mathematicalcreative thinking ability test and self-efficacy scale. The result of the validity by subject matter expert and media expert showed that the worksheet is considered excellent. The Initial field testing results indicate that worksheet is included in either category. The field testing results showed that (1) the student’s mathematical creative thinking aspect was effective because seen from the N-Gain of 0,54 which included in the category of moderate improvement and (2) the student’s self-efficacy was effective because seen from the N-Gain of 0,36 which included in the category of moderate improvement. It can be concluded that worksheet based on guided discovery effective way to improve the mathematical creative thinking ability and student’s self-efficacy
Application of Grey Numbers to Assessment of Mathematical Modeling Capacities
Get PDFMathematical modeling appears today as a dynamic tool for teaching and learning mathematics, because it connects mathematics with real world applications thus increasing the student interest on the subject. In the present paper a method is developed that uses grey numbers for evaluating student mathematical modeling capacities and a classroom application is presented illustrating it. This new assessment method is useful in particular when the student performance is evaluated with linguistic characterizations (grades) and not with numerical scores, which makes non feasible the calculation of the mean value of those grades. Grey numbers are indeterminate numbers which are defined with the help of the real intervals and they have found nowadays many applications in real life, science and engineering for handling approximate data
Design of ARCSI Learning Model with Scientific Approach for Teaching Mathematics in School
Get PDFThe study was aimed to obtain information regarding the design instructional of ARCSI learning model with the scientific approach for teaching mathematics in school. This learning model developed based on the learning conditions at Junior High School (SMP/MTs) in Bukittinggi City and Agam Districts of West Sumatera requiring a model of learning based on Islamic values, strategy in the motivation of ARCSI, and a scientific approach mandated in the curriculum of 2013. This learning model is designed for forming the character of learners in an Islamic way the learning process of mathematics that pleasant, and train students to think critically and comprehensively through a scientific approach. Synonymous ARCSI Learning Model with scientific approach, namely: (1) Attract the attention of learners by inviting praying/pleading to Allah Ta’ala, (2) Convey the purpose/benefit of learning and its application in daily activity, (3) The deliberations of the group to establish ukhuwah Islamiyah within the group, (4) a class discussion to establish ukhuwah Islamiyah classically, (5) Giving satisfaction to students with learning will make only because of Allah Ta’ala and the tradition of Prophet Muhammad SAW (6) Evaluate processes and the results of solving problems, and (7) Closing the learning by reading Hamdallah and greetings
Advocating Mathematics Teacher Research Prowess for Improved Professionalism
Get PDFWhile serving in the field of practice, teachers have continued to hold to the view that research is an activity carried out by professional researchers based outside the basic schools. This is because traditionally, class teachers have never been expected to comment on the theory and practice of their work. However, recent push by the Teacher Research movement across the globe has emphasized teacher research as a process in which educators note problems in the context of their own schools and classrooms and propose investigative methods appropriate to address the problems. On this premise, this review first considers the ramification of mathematics teacher research in improving professionalism in the teaching and learning of mathematics. Secondly, teacher professionalism in mathematics education was given a detailed coverage. Thirdly, the task of mathematics teachers as researchers was considered. The role of higher education in nurturing fruitful collaborations with basic schools was discussed along with the implications of mathematics teacher research for classroom practice in Nigeria
Analysis of Student Difficulties in Statistics Courses
Get PDFThe educational implementation is a learning process at all levels, students are required to follow certain lectures, including mathematics courses. Learning difficulties are a barrier to learning where children are not well educated, due to disturbances, both from student factors and external factors. learning, thus students are expected to catch up because of these obstacles. This research is classified into qualitative descriptive research that seeks to describe the analysis of student learning difficulties in statistical subjects. The subjects in this study were the fourth-semester students of 2018/2019 Mulawarman University. Research reveals things that are considered as a barrier factor for students in Statistics. In this study, the researcher collected information through documentation, tests, and interviews with students. The results of the analysis show that the difficulties of students in studying Statistics basically lie in the weakness of the concept. The results of the research conducted by the researcher were the existence of errors in process skills, errors in understanding questions, and errors in using notation. The solution to overcoming these problems is: for the eye teacher of Statistics to be able to develop learning strategies so that students can be more honed in their thinking skills and provide continuous problem training to students
