Some pristine habitat in the region of west Sumatera is less-explored due to low number of herpetologists in the area. However, many species were described as new to science based on morphological or molecular approaches. We conducted preliminary study to uncover the diversity of amphibians and reptiles in mount Sago, Sumatera Barat. In this study, we surveyed the amphibian and reptiles in the dry season. We performed a visual encounter survey along the hiking trails to the mount peak. A group of 3 persons searched systematically in the potential habitat. We stop at two points where these were located close to the stream to focus the searching at the potential habitat. A small collection was made comprised 25 individuals of 7 families and 15 species. At lower altitude (1000 meter above sea level/m.a.s.l), we found Chalcorana calconota, Fejervarya cancrivora, Odorrana hossii, Phrynoidis aspera, Microhyla heymonsi, Polypedates leucomystax, Megophrys nasuta, Limnonectes kuhlii, L. macrodon. At higher altitude (2567) masl), we collected Philautus polymorphus, Leptophryne borbonica, Leptobrachium hasseltii, and the juvenile of Broncochela hayeki. The limited finding to amphibians and reptiles were caused by the time of survey which was conducted in the dry season. Amphibians and reptiles less-active during dry season to prevent the loss of excessive water.
The learning process has a benchmark that refers to the achievements experienced by students, namely learning outcomes. Learning outcomes achieved by students have two influencing factors namely internal and external factors. These two factors that influence learning outcomes are interest and learning difficulties. The results of observations on the learning outcomes of students of SMPN 11 Padang in science are still low. Students say that science learning are numerous and difficult. The existence of students who score below the average and the lack of student interest shows the student's interest in learning in science is less and it can be assumed that students have difficulty learning science. Research is a descriptive study. Research uses a correlational study approach. Research subjects consisted of 30 people in class VIII G of SMP 11 Padang. To find out the relationship between variables expressed by the correlation coefficient, data analysis techniques are used using the Sperman Rank correlation. The correlation between student interest and learning outcomes is weak, that is -0.32, the contribution of 10.24% does not have a significant relationship. There is a significant relationship between learning difficulties and learning outcomes, medium criteria w ith a value of 0.59, contribution value is 34.81%. Correlation criteria for interests and difficulties with strong learning outcomes with a value of 0.66 and a contribution of 43.56%, as well as a significant relationship between variables. The results of the relationship between learning interest and learning difficulties with learning outcomes are strong and each variable has a significantly relationship.
This study aims to determine student’s perceptions of SMAN 2 Painan, because it has not been examined how students think about practicum. The type of research is descriptive and used quantitative approachment. The population of this study was class XI sain of SMA 2 Painan with propotional random sampling technique. The sample was 60 students.Thedatacollection techniqethrough representatives, observation and, questionnaires. The results showed that the practicum preparation of students was good74.80%, the implementation of students was very good 83.00% and the practical closing stage of students was good 79.00%.
Implementation of the 2013 curriculum is able to create students who have the ability to think at a higher level as the demands of the age to come. Students are expected to be able to think critically, creatively, and innovatively. One effort to improve students higher order thinking skills is to get students used to working on high level thinking skills. This research was conducted in October 2019 at SMAN 1 Kec. Kapur IX. The subjects in this study are the assessment instruments commonly used by teachers in school and the higher order thinking assessment instruments developed by the authors. The assessment instruments were tested on 24 students of Class XI MIPA 1 SMAN 1 Kec. Kapur IX. This type of research is a descriptive study that aims to analyze students higher-order thinking skills on the material excretion system using assessment instruments. The results of the analysis revealed that students high-level thinking skills were relatively low, This was evidenced by the results of the test of the questions obtained in the form of an average grade of 48. 17. The low cognitive level on the assessment instruments made by the teacher is one of the reasons for the low level of thinking ability of students. This causes students not accustomed to working on high-level thinking skills.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
