Authors: Soma Salim S
Published: November 2019

Reasoning-and-proving is believed by mathematics educators worldwide as an essential part of teaching and learning mathematics. In addition, relating a mathematics problem to real-world situation can help student making sense of a mathematics concept. One of the main sources used in Indonesia is mathematics textbook of Kurikulum 2013 which is provided by the government for free. Therefore, this study aims to look at students’ opportunities to solve rela- world related problems that involves reasoning-and-proving activities in the mathematics textbook focusing on the grade 7 textbook, chapter 1 about Number. The methodological approach and analytical framework used is a combination between framework of reasoning-and- proving activities and the use of real-world related problems. The results show that mathematical problems involving reasoning-and-proving activities provided by the textbook are still limited, counting for just around 20% while 80% of the problems cannot be identified as reasoning-and- proving. Slightly higher, real-world related problems in the textbook count for approximately 30% while 70% of them are not related to real-world situations. The results suggest that grade 7 students who use the textbook of Kurikulum 2013 have inadequate opportunities to learn real- world related problems and reasoning-and-proving activities from the book.

It can be seen that the average score of the students’ Science Process Skills in the experimental class is 70.34% and the control class is 63.30%. From hypothesis test thit = 7,536 and ttable value = 1,664, this means thit>ttable so hypothesis accepted. Average scientific knowledge of experimental class students 64,78 and control class 55,23. From hypothesis test for thit = 3.075 and ttable value = 1.664, this means thit>ttable so hypothesis accepted. From the results of this study can be concluded that the application of guided inquiry model influences the students scientific process skills and students scientific knowledge on the material of human excretion system of class XI MIPA Senior High School 8 Jambi City. The skills of students scientific processes and scientific knowledge can be well channeled with the help of guided inquiry learning models that involve active students during the learning activities. From the results of this study suggested that teachers can apply guided inquiry learning model in learning activities, especially practical activities that make students become enthusiastic in learning. This model makes students like a scientist so that raises the spirit in students to perform the whole procedure of practice to be implemented.

The present study aimed to determine the effectiveness of the problem solving model for science learning. The model effectiveness was determined by student’s activities, science process skill, and knowledge aspect. The data was obtained through experimental research with a randomized control-group pretest-posttest design. This study was conducted at three different school, namely state junior high school 1 Padang, state junior high school 12 Padang and national junior high school Padang. Two classes of each school were choosen as simple random sampling. The instrument were observation sheets to collect student activities and multiple choice questions to collect students SPS and knowledge aspect. Student activity data were analyzed using the Cohen’s Kappa formula and percentage. The data of improving SPS and knowledge aspect were analyzed by U Mann-Whitney test using SPSS 19. The results revealed that the PS models proved effective which was based on the students’ activities in which they were categorized as a very active category, as well as to improve students’ SPS and knowledge aspect. Therefore, reflected from the findings of the present study, it is recommended for the teachers to implement the use of PS models in science learning at junior high school.

Genetic learning elaborates on several learning models and is applied in accordance with the characteristics taught in RQA learning, trained to read the material specified, make questions according to the material with levels and answer themselves and be discussed in groups to be presented in class. The purpose of this paper is to reveal useful information about nano biology education with the RQA strategy the concept of genetics based on metacognitive. So genetics is known as one of the key areas of Nano Biology, and compared to genetics there is no other field that has the role to shape our knowledge of things in life. Metacognitive skills are a person’s awareness of what is actually known, regulated in order to be able to effectively manage metacognitive activities, this is urgent as early as must be known and contains declarative, procedural, and conditional knowledge while regulations include activities in planning, monitoring, testing, repairing and evaluating students. The conclusion is that biological nano education with metacognitive-based RQA strategies is urgently needed to comprehensively master the biology concept.
Biodiversity and ecological phenomena in pranatamongso calendar: basic knowledge and goal for optimizing of crop production in javanese farmers

Published: November 2019

Human living dynamic is a complex of technology and society system in which science, technology, and also cultural beliefs are developed and have been growing together toward a life sustainability. Hence, cultural beliefs and practices hold by a distinct tribes or society in Indonesia represent their values which could be influenced by their environmental factors. Geophysical characteristics, climatology dynamics and the presence of living organisms mainly plants and animals are some essential sources of their cultural-based scientific knowledge and may represent as an ethno-ecology view. For Javanese farmers, as an example, this cultural-based science knowledge and practice have been developed and well-known implemented for their agriculture system by which the season cyclic (dry and rain) as well as animals ecological dynamics may determine the way of farming they have been carried out. This ethno-ecology view known as Pranotomongso which considers the traditional knowledge based on a careful observation on climate dynamics and its factors, such as sun and moon positions, or wind intensity, also their impact on plants and animal interactions in ecosystem. A deep-understanding of Pranotomongso leads an effort to optimizing and sustaining the crop production by maintaining and controlling both plants and animal diversity. As a cultural-based calendar, could Pranotomongso be utilised for examining the biodiversity information as well as crop sustainability? Regarded to this basic question, this paper provides an insight discourse based on the way Pranotomongso is developed in term of scientific perspectives, such as rainy and dry season calculations, and both the plants and animal diversity existence.

Students need science process skills (SPS) to they investigate in learning. Teachers at senior high schools in Manokwari have measured student skills, but are not specific to science process skills. The contribution of SPS towards student cognitive achievement became the focus in this research. 88 participant research was taken from XMIA class of SMA Negeri 01 Manokwari. Measurement of SPS and cognitive achievement of students used the test. The results of the data analyzed used a simple regression found that P < 0.05, it means that there was a contribution of SPS towards student cognitive achievement. The contribution of SPS towards student cognitive achievement was 55.7%. It can be concluded that the SPS has a contributed towards cognitive achievement of students when the teacher applies guided inquiry-based learning in his class.
