Education in 21st century is very relevant to the purpose of education in Indonesia. Global era and the integration of technology in education, helped accelerate the synergy of knowledge across disciplines, thus giving birth to a new field. Learning aimed at creating an atmosphere of active, critical, analytical, and creative in solving problems through the development of thinking skills. Science (biology) essentially contains four elements are scientific processes, the product (scientific knowledge), attitudes (scientific attitudes), and technology. Processes in science implies manner or scientific activity for natural phenomena to describe the product obtained in the form of science facts, principles, laws, or theories. Science (biology) containing six elements are active learning, discovery / inquiry activity approach, scientific literacy, constructivism, science, technology, and society, and the existence of truth.There are two things that can be done by LPTK in optimizing the implementation of Curriculum 2013 are: 1) Strengthening understanding of the biology teacher candidates about the nature and characteristics of biology teaching; 2) Creating an academic situation so that prospective biology teachers have insight and knowledge about the importance of the role of science (biology) and as well as the direction of learning in the future. Learning aimed at creating an atmosphere of active, critical, analytical, and creative in solving problems using science process skills

<p>Purpose of this research is to know the influence of of Problem Based Learning based on localities models toward scientific literacy of students of grade X. The research was a quasy experimental research used posttest only non-equvalent control groups. Population of the reserach was the students of grade X in the second semester of SMA N 1 Cepogo in the academic year 2013/2014.  Sampling technique was cluster sampling method. Collected data was connucted by test and non test method. The test for measuring scientific literacy was a five essay test, which consist of three aspects, namely: to identify scientific issues, to explain phenomena scientifically, and to use scientific evidence. The non test method were observation, and documentation. Hypothesis test were analysed by t-test using SPSS version 16. The results of the research were received H1 and rejected H0. It means there was a difference of scientific literacy between control class (conventional models) and experiment class using Problem Based Learning based on localities. The average score of scientific literacy in experimental class was 48,47 and score of control class was 26,95. It was also found that the highetst average of scintific literacy in the experimental class was aspect to use scientific evidence, while the lowest one was to identify scientific issues. The conclusion of the research was Problem Based Learning based on localities models significantly influenced  the scientific literacy of grade X students SMA N 1 Cepogo.</p><p align="center"> </p><p>Key Words: Problem Based Learning, scientific literacy, based on localities</p>

The purposes of this research were: 1) development of students worksheet Problem Based Learning (PBL) based on Local Potential; 2) test feasibility of the PBL model; 3) determine the effectiveness of PBL model. Analysis of the data used for research and development are qualitative and quantitative descriptive analysis, as well as the percentage techniques. Research and development of PBL models based on local potential uses 4-D model. The results of research and development showed: 1) product of PBL-based models are developed based on the stages of the Local Potential PBL syntax that uses indicators of critical thinking skills, 2) feasibility of the model PBL-based Local Potential according to experts is very well qualified with average of 92,1 %, qualified by education practition is very well with average of 94,5 %, whereas according to qualified students an excellent with average of 88,2 %; 3) student's worksheet PBL-based Local Potential effectively improve critical thinking skills and learning results with gain value 9 and N-gain value 0.28 at low category. Based on result of t scores obtainable gain value 9.06 and N-gain value 0.420 at medium category. Keywords:Research and development, PBL model, local potential, biotechnology, critical thinking skills, learning outcomes LATAR BELAKANGMahasiswa seringkali kesulitan dalam mencari literatur perkuliahan khususnya untuk mata kuliah Bioteknologi. Sumber belajar yang digunakan masih terbatas pada print out dari materi kuliah (Power Point) yang dibuat oleh dosen serta hanya sebagian kecil yang aktif mencari sumber belajar melalui internet. Mahasiswa kurang memiliki kemampuan memecahkan masalah, yang terindikasi dari kurang aktifnya mahasiswa dalam berdiskusi sehingga diskusi tidak berjalan efektif. Selain itu dalam menyelesaikan tugas-tugas yang diberikan oleh dosen, mahasiswa belum memiliki rasa tanggung jawab, serta belum dapat mengerjakan tugas-tugas secara mandiri. Perkuliahan Bioteknologi masih bersifat teoritis dan bersifat ceramah serta kurang memaksimalkan kemampuan mahasiswa dalam melakukan pemikiran secara kritis. Perkuliahan Bioteknologi yang sudah dilaksanakan menggunakan instrumenberupa LKM, namun LKM yang digunakan selama ini kurang memberdayakan kemampuan berpikir kritis mahasiswa karena hanya melakukan kegiatan sesuai petunjuk tanpa memberikan kesempatan pada mahasiswa untuk menemukan konsep sendiri dalam perkuliahan.Melalui perkuliahan Bioteknologi diharapkan mahasiswa mampu berpikir kritis menemukan solusi terhadap permasalahan dalam kehidupan nyata. LKM yang mampu mendorong mahasiswa berpikir kritis melalui pemecahan masalah dalam kehidupan nyata sangat perlu dikembangkan guna menyelesaikan permasalahan tersebut.Model PBL (Problem Based Learning) merupakan suatu pola atau suatu rencana yang digunakan sebagai pedoman dalam merencanakan pembelajaran dengan memunculkan suatu permasalahanautentik dari lingkungan sekitar secara nyata yang harus diselesaikan. Sintaks dari model Problem Based Learning adalah diawali darimengorientasikan masala...

<p class="5abstrak">The research and the development of the modules aims to know: 1) The characteristic of environmental pollution module based on problem posing with spider concept map; 2) The procedure of developing environmental pollution module based on problem posing with spider concept map; 3) The feasibility of environmental pollution module based on problem posing with spider concept map to empower students’ science process skills and students’ analyze abilities; and 4) Effectiveness of environmental pollution module based on problem posing with spider concept map to to empower students’ science process skills and students’ analyze abilities. The method used in the research is Research and Development (R&amp;D) modification of Borg &amp; Gall (Tim Puslitjaknov, 2008: 10-11). The subject used in preliminary field test consisting of 10 students’, the main field subject consisting of 10 students’ and opeational field subject consisting of 32 students’ SMAN 1 Sumberlawang. The instruments used in the research, mainly: questionaire, observation, interview and test. The operational field was conducted using one group pretest-postest design. Students’ science process skills and students’ analyze abilities were tested by paired sample t-test and counted by normalized gain score. The results of the research can be concluded that: 1) The characteristic of vironmental pollution module based on problem posing with spider concept map, mainly: aspect of students’ science process skills and students’ analyze abilities, science literate abilities (be able to understand, read, write and think in terms of science); 2) The development of environmental pollution module based on problem posing with spider concept map used modification Borg &amp; Gall, mainly: preliminary research, planning, developing the initial products, preliminary field test, major product revision, main field test, the operational product revision, operational field, revision of the final product, the dissemination and the implementation of the product; 3) The feasibility of environmental pollution module based on problem posing with spider concept map average obtained is 3,51 that’s “very good” categories; and 4) The environmental pollution module based on problem posing with spider concept map is effective to empowering students’ science process skills with 0,60 N-gain score that’s “middle” categories and empowering students’ analyze abilities with 0,57 N-gain score that’s “middle” categories.</p>
