Abstract

Abstract Regression model of bi-respond nonparametric is a regression model which is illustrating of the connection pattern between respond variable and one or more predictor variables, where between first respond and second respond have correlation each other. In this paper, we discuss the estimating functions of regression in regression model of bi-respond nonparametric by using different two estimation techniques, namely, smoothing spline and kernel. This study showed that for using smoothing spline and kernel, the estimator function of regression which has been obtained in observation is a regression linier. In addition, both estimators that are obtained from those two techniques are systematically only different on smoothing matrices. Keywords: kernel estimator, smoothing spline estimator, regression function, bi-respond nonparametric regression model. AbstrakModel regresi nonparametrik birespon adalah suatu model regresi yang menggambarkan pola hubungan antara dua variabel respon dan satu atau beberapa variabel prediktor dimana antara respon pertama dan respon kedua berkorelasi. Dalam makalah ini dibahas estimasi fungsi regresi dalam  model regresi nonparametrik birespon menggunakan dua teknik estimasi yang berbeda, yaitu smoothing spline dan kernel. Hasil studi ini menunjukkan bahwa, baik menggunakan smoothing spline maupun menggunakan kernel, estimator fungsi regresi yang didapatkan merupakan fungsi linier dalam observasi. Selain itu, kedua estimator fungsi regresi yang didapatkan dari kedua teknik estimasi tersebut secara matematis hanya dibedakan oleh matriks penghalusnya.Kata Kunci : Estimator Kernel, Estimator Smoothing Spline, Fungsi Regresi, Model Regresi Nonparametrik Birespon.

Abstract

Applied learning by teachers greatly affect the success of students in learning.  The low learning and activity  outcomes are not indication yet optimal learning. This research is   the PTK aimed to improve learning and activity  outcomes math class VIII / 4 SMP Kosgoro 1 Bandar Sri Bhawono East Lampung semester Academic Year 2012/2013, through Mathematic Realistic Approach. Action is  conducted in three cycles, each cycle including: planning, implementation, observation and reflection. Data were collected through observation of student activity at each meeting and learning outcomes gained through the end of each test cycle. Based on data analysis results of this research note that an increase in the percentage of students active and learning outcomes in each cycle. Percentage of students active continuted in Cycle I, II, III was 51.35%, 69.44% and 81.08%. Percentage of students who pass the learning continuted cycle I, II, III was 51.35%, 66.66% and 78.37%. From these results it can be concluded that the application of PMR in learning can increase student, activity and the result of mathematic learning class VII1 / 4 SMP Kosgoro 1 Bandar Sri Bhawono Odd Semester Academic Year 2012/2013.Keywords: Mathematics Realistic Approach, Activities, Learning Outcomes

Abstract

This paper presents how the model is Problem Based Learning (PBL)applied to the material (IPA) in grade IV Elementary School. PBL is a learning approach that uses real-world problems as a context for students to optimize students' thinking skills through a systematic group or team work process, so that students can empower, hone, test, and develop their thinking skills on an ongoing basis. The PBL learning model also provides opportunities for students to stimulate higher-order thinking. The steps of the learning model have 5 stages, namely the learning model. the PBL lesson implementation phase in the process has five phases, the first 1) The student orientation phase on the problems contained in the PBL, 2) The stage of organizing students to learn, 3) The stage of guiding individual and group investigations, 4) The stage of developing and presenting the results, and 5) The stage of analyzing and evaluating the problem solving process.

Abstract

Effective teaching methods are essential to facilitate students' cognitive, social, and emotional development. One of the approaches proposed in the Merdeka Curriculum is Project Based Learning (P5), which invites students to be directly involved in the learning process through real projects. The research method used is a causal quantitative method with a population of 5th grade students at SDN Karangesuki 4 with a sample size of 54 students. The data analysis technique uses a t-test with a significance level of 5%. The T-test used is a separated variant or polled variant with a calculation tool in the form of SPSS. Based on the results of the research and discussion, several conclusions can be put forward. The conclusions that will be put forward in this research are as follows. 1) There is an increase in collaboration skills between students who learn using project-based learning and students who learn using LKPD (Learner Worksheets) on the theme "Use of Used Goods" class 5 at SDN 4 Karangbesuki, Malang City. It can be seen that the post-test average for the experimental group using project-based learning was 19.058, while the post-test average for the control group was 14.117. Based on the average increase in students' collaborative learning skills, it can be concluded that the increase in students' collaborative learning skills is higher in children who use project-based learning. 2) The results of the analysis of student responses on collaborative learning skills showed that the final percentage of student responses was 81.18% which was classified as very positive. Keywords: Project Based Learning (P5); Student Learning Collaboration Skills.
