Penelitian ini merupakan penelitian deskriptif yang bertujuan untuk mengetahui hasil belajar siswa pada materi peluang setelah diterapkan model pembelajaran Connected Mathematics Project (CMP) di kelas VIII. Subjek penelitian adalah siswa kelas VIII.1 SMPN 1 Palembang yang terdiri dari 29 orang. Teknik pengumpulan data yang digunakan, yaitu tes tertulis yang terdiri dari tiga soal uraian dan wawancara sebagai pendukung data tes. Hasil penelitian menunjukkan bahwa hasil belajar siswa pada materi peluang secara keseluruhan dikategorikan baik dengan rata - rata adalah 76,09, dengan rincian siswa terkategori sangat baik sebanyak 20,69%, terkategori baik sebanyak 44,83%, terkategori cukup sebanyak 24,14%, dan terkategori kurang sebanyak 10,34%. Siswa yang terkategori sangat baik dan baik secara keseluruhan mampu menentukan peluang kejadian dengan mencari banyak ruang sampel dan kejadian suatu percobaan dengan baik. Sedangkan siswa yang terkategori cukup dan kurang masih belum mampu menentukan peluang kejadian yang disebabkan oleh kesalahan dalam menentukan banyak ruang sampel dan kejadian suatu percobaan. Kata kunci: hasil belajar; CMP; peluang This research is a descriptive research that aims to find out student learning outcomes in material of probability after applying model of learning namely Connected Mathematics Project (CMP) in class VIII. The subjects of this research were students of class VIII.1 from SMPN 1 Palembang which consists of 29 students. Technique of collecting data that used on this research were written test which consist of three essay question and interview as a supporter of test data. The research results shows that student learning outcomes in the material of probability overall are categorized good with the average is 76.09, with categorized of excellent students as much as 20.69%, good categorized as much as 44.83%, enough categorized as much as 24.14% , and the low categorized as much as 10.34%. Students who are categorized excellent and good, overall are able to determine the probability of the event by finding sample space and events of an experiment well. While students who are categorized enough and low still have not been able to determine the probability of events caused by errors in determining the sample space and the event of an experiment. Keywords: learning outcomes; CMP; probability

Penerapan Model Connected Mathematic Project untuk Meningkatan Kemampuan Berpikir Kreatif Matematis Siswa Madrasah Aliyah

This study aims to find out (1) whether or not there is an increase in mathematical creative thinking skills of Madrasah Aliyah students; (2) Student activities during mathematics learning with the connected mathematics project Learning model. This research was conducted at the Aliyah Mathla'ul Anwar Madrasah Menes Center in the first semester of the 2017/2018 school year. The research method used is the quasi-experimental method. The population in the study was class XI Madrasah Aliyah Mathla'ul Anwar Pusat Menes Pandeglang District, while the sample was taken randomly from two classes from six classes in the school. Class XI Religion is an experimental class, namely a class that has learned to apply the connected mathematics project and class XI IPS as a control class, namely a class whose learning applies conventional learning. Question test data were analyzed by descriptive and inferential statistics using the average difference test. The results of the study show: (1) There is an increase in mathematical creative thinking skills using the connected mathematics project learning model; (2) Positive student activities during mathematics learning with the connected mathematics project learning model.

Pengaruh Model Pembelajaran Connected Mathematic Project terhadap Kemampuan Pemecahan Masalah Matematika

<pre><em><span lang="EN-US">The purpose of the research is to determine the Impacts of Connected Mathematics project Learning Method on Student’s Mathematics Problem solving Skills at SMP Putra Bangsa. The research method is experiment. Sample of the research is taken from affordable population by using cluster random sampling technique. Size of population is 40 students that divided into two class. The instrument used is essay test as much as 6 items. Analysis technique in this research is t test. Testing requirements of data analysis is Liliefors test for normality and fisher test for homogeneity test. In experiment class L test = 0.1143 and L table = 0.190. in control class L test = 0.0868 and L table=0.190, because L test ? L table, so Ho is received and it can be concluded that the data of the population in normal distribution. F test for homogeneity , F test=1.826 and F table=2.17, because F test? F table, so both of class has same varians or homogen. The result of data analyze t test=3.16 and t table=2.03 at significance level ?=0.05 and freedom degrees=38, so there are impacts of connected mathematics project learning model on mathematics problem solving skills.</span></em></pre>

Enacting Proof-Related Tasks in Middle School Mathematics: Challenges and Opportunities

Discussions about school mathematics often address the importance of reasoning and proving for building students' understanding of mathematics. However, there is little research examining how teachers enact tasks designed to engage students in justifying and proving in the classroom. This article presents results of a study investigating the processes and outcomes of implementing proof-related tasks in the classroom. Data collection consisted of observations of 7 middle school classrooms during implementation of proof-related tasks—tasks providing opportunities for students to produce generalizations, conjectures, or proofs—in the Connected Mathematics Project (CMP) curriculum by teachers experienced in using the materials. The findings suggest that students' experiences with such tasks are insufficient for developing an understanding of what constitutes valid mathematical justification.

Readers Write: March 2009

Beauty is in the eyes of the beholder. I have been a long-time user of the Connected Mathematics Project materials and have literally worked every problem offered for all three grade levels so as to anticipate how the problem might play out in the classroom. My knowledge of mathematics and teaching has grown by leaps and bounds from solving each problem; from studying the teacher editions, in themselves a wealth of support; and by working with colleagues and students. I enter my classroom believing anything can happen if I let it. I have seen students at work on worthwhile mathematical tasks in my own classroom, as well as the classrooms of many others. My stories are many, my enthusiasm abounds, and my belief that every child can learn is steadfast.

Innovation in Curriculum: Algebraic Concepts: What's Really New in New Curricula?

New mathematics curricula serve middle grades students well when they provide students with richer and more accessible introductions to a wide range of mathematical content. New curricula also serve teachers well when they lead us to examine and reflect on what and how we teach. When these curricula enter our working lives and conversations, we are often forced to question exactly what is “new” about them and how this “newness” may affect our students' learning. To address this issue and, we hope, to support further reflection and discussion, we take a closer and more careful look at what is new in one middle school curriculum's approach to algebra. The curriculum we examine is the Connected Mathematics Project (CMP) (Lappan et al. 1998), particularly the eighth-grade units, but the issue of what is new in algebra is relevant to many other innovative middle school curricula, as well.

Innovation in Curriculum: Reflections on Developing Formal Mathematics and the Connected Mathematics Project

Sound conceptual understanding is crucial to the development of students' formal mathematical knowledge. However, this conceptual understanding rarely develops from a single lesson, but rather from related experiences over time. For example, to use and apply formulas for area in a powerful way, students need to understand that the conventional measure of area is based on counting squares that cover a surface, and further, they need to understand the ways in which the concept of area as covering-with-square-units is related to the formulas for area.
