ABSTRACT This study intended to investigation the impovement of students mathematical communication by using Google SketchUp and direct Instruction, the interaction between students' learning ability and learning method in term of mathematical communication skills, and also students' attitudes toward Google SketchUp. The study used quasi experimental design and employed control group with pretest  and control final test. The population of study was eight grade students at of one a public Junior High schools in Lembang and two classes was choosen as a sample. Experimental group was used Google SketchUp and control group was used direct Instruction learning. The data were collected though students understanding of mathematical communication test, Likert scales, and student journal. The data were analyzed using quantitative and qualitative. The quantitative data were analyzed using pretest and posttest and the normalized gain of mathematical communication, and also conducted test both of groups which are performed the mean difference test between two populations and two-ways ANOVA. The qualitative data were analyzed using students' attitudes toward Google SketchUp learning. The finding of this study suggested that Google SketchUp learning was effective in improving students' of mathematical communication . More over, result showed that there is interaction between students' learning ability (high, medium, and low) in terms of students' mathematical communication and also positive students' attitude toward Google SketchUp learning. Key words:  Google SketchUp program and mathematical communication   ABSTRAK Penelitian ini bertujuan untuk menelaah peningkatan kemampuan komunikasi matematis siswa yang mendapatkan pembelajaran dengan Program Google SketchUp dan pembelajaran langsung, interaksi antara pembelajaran  yang digunakan dengan kategori kemampuan siswa dalam hal kemampuan komunikasi matematis siswa, serta sikap siswa terhadap pembelajaran dengan Program Google SketchUp. Desain penelitian ini adalah kuasi eksperimen dengan kelompok kontrol tes awal dan tes akhir. Populasi penelitian ini adalah seluruh siswa di salah satu SMP Negeri di Lembang dengan sampel penelitian siswa  kelas VIII sebanyak dua kelas yang dipilih secara purposif.

The main goal of this study is to present the effectiveness improvement of student’s creative thinking skills using CBL implemented in STEM education and CBL combined with worksheet PSL. The STEM education perspective used in this study is a separate science discipline (Physics) that incorporates other disciplines. The research method used in this study is a quantitative method with a quasi-experimental research design. The research includes a pre-test-post test control group design. The subjects of the research consist of forty-five students in 10th grade of one of the vocational schools. The instrument used in this study is an essay test consisting of four questions with indicators of fluency, flexibility, and originality. The enhancement of students’ creative thinking skills is known by analyzing normalized gain (g) on the experimental group and control group. A non-parametric test and Cohen’s Kappa test were used to examine differences improvement of student’s creative thinking skills with the IBM Statistics SPSS 20.00 program at .05 significant levels. As a result of the research, it was found that CBL implemented in STEM education has a higher improvement for students of creative thinking skills than CBL combined with worksheet PSL. CBL implemented in STEM education also has a major impact on improvement of students’ creative thinking skills.

The objective of this study is to measure whether there is or not significant effect of teaching reading by utilizing Hot Potatoes software toward students’ reading comprehension of descriptive text. The variables used were the teaching treatment of Hot Potatoes Software as the independent variable and the students’ reading comprehension of Descriptive Text as dependent variable. Then, the research designed was Quasi-experimental design and the presentation of data used was quantitative. The data were obtained from the eleventh grade, of which 28 students were taken as sample. The students are divided into two groups; experiment group consisted of 12 students and control group consists of 16 students. To get the data, the pre-test and post-test were applied and then analyzed using t-test formula. The researcher had concluded that there is Significant effect of Hot Potatoes Software toward the students’ reading comprehension achievement. The result showed that mean of students’ post-test was increased. It is proved by the t-test (8.54) which is higher than t-table (2.05) at level of significance 5%. It means that the alternative hypothesis was accepted and it proved that Hot Potatoes Software had significant effect toward students’ reading comprehension of Descriptive Text

The problem of this study is “Does Concept Oriented Reading Instruction (CORI) enhance students’ reading achievement?” The design of this study was quasi-experimental. The sample of this study was taken from the population by using purposive sampling. The experimental group consisted of 39 students while the control group consisted of 35 students. The data were collected by using two instruments; test and questionnaire. The test was given twice to each group in order to see whether or not there was significance difference of pretest and posttest either in experimental or control group and whether or not there was significance difference of experimental and control group in terms of their posttest score. To prove the hypothesis, the data from pretest and posttest of experimental and control group were analyzed by applying paired sample t-test and independent sample t-test. The calculation was run by using SPSS computer program. The result of the study shows there was significance difference of students’ reading achievement between experimental and control group. Besides, the use of CORI as reading strategies was proved as effective reading strategies to enhance students’ reading achievement.
