Abstract

This research was motivated by the low level of students' scientific literacy which is one of the educationalproblems in Indonesia with the average achievement of scintific literacy scores being still low. The aim of the research is to determine the scientific literacy abilities in the competency aspect, knowledge aspect, context aspec and attitude aspect of high school students in Batangtoru District. This assesment is based on the Program for International Student Assessment (PISA) standars. The method used is a quantitative approach. The subjects of this research consisted of 92 students in Batangtoru sub-district. The instrument used is a written test in the form of a description to determine scientific literacy abilities based on threeaspects (competence, knowledge and context). An average percentage of 27.45% was obtained in the verypoor category. Then, to assess aspects of attitude, the instrument, used is a non-test, namely in the form of a questionnaire. Obtained an average percentage of 73.49% in the good category.

Abstract

The research carried out is related to assessing the use of learning models. The learning model used is the Instructional Design development model on Static Fluid material in Class XI SMA Negeri 1 Batangtoru. This model requires students to be more active in class. The use of this model will be combined with the use of modules as a learning resource, so that it can become an alternative for implementing learning. The aims of this research are 1) to describe learning using modules as an effective learning resource, 2) to describe student activities while using the Instructional Design Development Model in Static Fluid material in Class XI SMA Negeri 1 Batangtoru with modules as a learning resource, 3) to describe the results student learning while using the Instructional Design development model in Static Fluid material in Class Learning Resources.This research is action research which is developmental and pre-eliminary in nature, so it only uses one class. The research design uses Kemmis MC Taggart's cycle model with a One Group Pretest-Posttest Design learning pattern. This research was carried out at SMA Negeri 1 Batangtoru class XI MIPA1, with 34 students. This learning consists of three cycles. The implementation of learning in each cycle uses different syntax, so that you can find out which cycle is most effective. Student learning activities are divided into three stages, Instruction stage, Doing stage, and Evaluating stage. Student learning activities increase in each cycle. Student activities are in the active to very active category. The highest student activity is in cycle 3 with the very active category. Student scores increase from pretest to posttest in each cycle. The highest posttest average score was in cycle 2. The highest n-gain was also in cycle 2 with the medium category. Student learning retention is included in the very strong category. The most effective learning uses the Instructional Design development model in Static Fluid material in Class XI SMA Negeri 1 Batangtoru with modules as learning resources located in cycle 2. Based on the analysis of research data results, it can be concluded that the Instructional Design development model for Static Fluid material in Class XI SMA Negeri 1 Batangtoru with modules as learning resources is suitable for use in Static Fluid material in Class This model can be an alternative learning model implemented by teachers. This research requires thorough preparation, so that further research can be better prepared

Abstract

Development is an effort to improve technical, theoretical, conceptual and moral abilities according to needs through education and training. So development is more realistic, not just idealistic. Education is difficult to apply in life, development is an effort to improve quality both in terms of material and its substitutes. The research aims to produce an assessment instrument to measure scientific process skills in optical materials, pressure and wave vibrations. The research instrument is a question feasibility test questionnaire addressed to validators and a student response questionnaire. The research subjects were 30 students of class XI IPA1 SMA Negeri 1 Batangtoru in Batangtoru Dis. The test developed is in the form of reasoned multiple choice and essay. The research results show that: (1) The validity or feasibility of the PPP instrument developed based on experts is valid and suitable for use; (2) Validity of the PPP assessment instrument items developed with valid criteria; (3) The reliability of the questions from the KPS instrument is very strong for multiple choice questions on optics and wave vibrations; strong reliability for pressure material questions; and moderate reliability for essay questions on elasticity, fluids, Newton's laws and wave vibrations; and (4) The questions  questions with a medium level of difficulty

Abstract

Physical environment plays a strategic role in supporting sustainable development. Increasingenvironmental damage, such as climate change, pollution, and exploitation of natural resources, shows that development that does not consider environmental aspects will have a serious impact on human life. Therefore, Physical environment is an important instrument for shaping public awareness, knowledge, attitudes, and behavior to be more responsible towards the environment. This study aims to examine the concept of Physical environment and its relationship with sustainable development through a literature review approach. Data were obtained from various sources, including books, national and international scientific journals, and official documents from relevant institutions. The results of the study show that Physical environment plays a role in instilling values of sustainability, increasing environmental literacy, and encouraging community participation in maintaining a balance between social, economic, and environmental factors. Therefore, a key step towards achieving sustainable development is to integrate Physical environmentinto formal and informal physics institutions.
