Effect of Module use with Scientific Approach on Archaebacteria and Eubacteria Material applied in Discovery Learning Model on Student Biology Learning Competence

The learning process of biology at SMAN 1 Batusangkar has used modules but has not used a scientific approach, so that it fully complies with the demands of the 2013 curriculum. While the models used in the learning process are not fully in accordance with the demands of the 2013 curriculum. 2013, the module can be used with a scientific approach in the Discovery learning learning model in the learning process. The aims of this study is to see the effect of the use of modules with a scientific approach to the material of Archaebacteria and Eubacteria in the Discovery learning learning model on biology learning competencies of students of class X MIPA SMAN 1 Batusangkar on Archaebacteria and Eubacteria. This research is an experimental study with the research design of The Static Group Comparison Design. The results showed that the use of modules with a scientific approach to the material of Archaebacteria and Eubacteria in the Discovery learning learning model did not have a positive effect on the competency of biological knowledge and had a positive effect on the competency of attitudes and biology skills of students.

The Analysis Scientific Attitudes in the Implementation of Science-Biology Learning Practicum for Class VIII Students in SMPN 34 Padang

Scientific attitude is a collection of several important aspects that describe the interaction of each student. This study aims to study the quality of scientific attitudes carried out by students when carrying out practical learning in Natural Sciences-Biology Class VIII SMPN 34 Padang. The aspects of scientific thought discussed include: 1) curiosity, 2) respect for data, 3) critical thinking, 4) discovery and creativity, 5) open thinking and working together, 6) perseverance, and 7) sensitive to Surrounding environment. This type of research is a descriptive study, with a total of 280 students and a sample of 108 students consisting of 9 classes. Sampling using Proportional Cluster Random Sampling technique by taking ± 40% of the total population. Data collection using questionnaires and observation sheets. Data analysis was performed quantitatively with the percentage analysis method. From this study obtained research on scientific quality assessment on every aspect of the aspect curiosity has good criteria, aspects of respect for data that have adequate criteria, critical aspects of thinking have sufficient criteria, aspects of discovery and considerations that have good quality, aspects of open thinking and working together have good criteria, perseverance aspects have good criteria, and aspects that are sensitive to the environment have criteria. So, the quality of scientific thinking of students in the implementation of science-biology learners.

The Influence of Problem Solving Model Toward Students’ Critical Thinking Skills

The aims of this study was to find whether there was an influence of the Problem Solving Model towards critical thinking skills of students of grade XI in SMAN 9 Padang. A Quasi Experiment method with The Post-test Control Group Only Design was used in this study. Students were grouped in an experimental group (Problem Solving model) and a control group (Direct intruction). The data from a test were analyzed using t-test with a=0,05.

The Validity and Reliability of The Instrument Assessment of Higher Order Thinking Skill on The Biological Scope Materials

High Order Thinking Skill (HOTS) requires students to connect, analyze, and also transform their knowledges and experiences. To determine students' high-level thinking skills, we can use assessment instruments. A good instrument should be valid and reliable so it is feasible to measure and assess what it wants to be measured and assessed. Therefore it is necessary to know the level of validity and reliability of the higher order thinking assessment instruments. The instrument used in this study in the scope of biology material. This type of research is descriptive research. The subjects of this study were students of grade X MIPA 5 SMA 5 Padang. Based on the results of data analysis, the assessment instrument of high order thinking skill on biological scope material is logically valid, empirical valid and reliable.

Student’s Science Literacy Skills with Problem Based Learning in Senior High School in Tanjungpinang

The average national exam score of biology subject in high school in Tanjungpinang tends to be the lowest among other subjects. It is assumed that the ability of student science literacy also tends to be weak. The role of teacher is very important to improve student’s science literacy ability. Applying various learning strategies to create meaningful learning processes is one of the teacher's role. The strategy is Problem-based Learning (PBL) model. This research was conducted to determine science literacy ability of high school students in Tanjungpinang using PBL learning strategy. Research was conducted in SMA 4 and SMA 6 in Tanjungpinang. It is a quantitative approach with Quasi Experiment. PBL is free variable and science literacy skills as bound variable. Researcher uses tests, observation sheets and interviews as research instruments. Based on the results of this research can be concluded that implementation of PBL gives significant difference for student’s science literacy in tenth grade in SMA 4 and SMA 6.

Improving Student Biology Learning Outcomes through STAD Type Cooperative Learning on Plant Material

The learning process carried out at school is expected to be able to increase the learning activities and learning outcomes of students. Student biology learning outcomes and activities at SMAN 1 Koto XI Tarusan are still not satisfactory. The methods and strategies used so far have not been able to improve students' learning activities and outcomes. One of the efforts to increase the activities and learning outcomes of students is through STAD type cooperative learning and the internet as a source of teaching materials. This research was conducted in the even semester of Academic Year 2011/2012 in Class X.7 of SMAN 1 Koto XI Tarusan. This research was conducted in two cycles, each cycle consisting of four stages: planning, implementing, observing, and reflecting. The research data were obtained through observation sheets and learning outcomes tests given at the end of the cycle. The results of the analysis of the data cycle I and cycle II showed an increase in student learning activities and learning outcomes. Student learning activities have increased by 8%, and student learning outcomes have increased by 10%. It can be concluded that the use of STAD cooperative learning types and the internet as a source of teaching materials can increase the activity and learning outcomes of students in class X.7 of SMAN 1 Koto XI Tarusan.
