Abstract

Animal behavior is a response to external environmental conditions through detection by certain senses. Changes in physical factors in the environment before the earthquake (magnetic field anomaly) also influence the expression of specific behavioral changes in birds, namely the flight activity. However, scientific explanation of changes in orientation or direction of flight before the earthquake was not yet available. This article aims to describe the mechanism of bird's biological response to changes in the magnetic field before the earthquake. This study is a literature review. The results of theoretical synthesis explain that birds use magnetic receptors and light receptors that recognize changes in the magnetic field before the earthquake followed by an increase in the amount of intracellular calcium ions. Abnormal amounts of calcium stimulate the formation of more ATP which activates the function of actin and myosin, therefore muscle cells experience a bathmotrope effect expressed in the form of changes in flight direction.

Abstract

One of the subjects that must be taken by distance education students of Physics of Universitas Terbuka (UT) is PEFI4201 Physics Learning Strategy. The average score obtained by students in PEFI4201 courses is low. To master the concept of this course students are given learning assistance services in the form of online tutorial (tuton) in addition to studying the module as the main teaching material. However, the students' activity in the tuton is less encouraging. Thus the social media WhatsApp (WA) is required to enable students to follow the tutons. The purpose of this research is to describe WA communication process in support of tutons implementation. The method used in this research is descriptive qualitative and quantitative to analyze WA communication process in support of tutons implementation. The results of this study obtained that WA strongly supports student activeness in tutons. Communication occurring from 28 August to 29 October 2017 consists of academic administration 6.67%; reminder 22.42%; explanation of material 62,42%; and technical explanation elearning 8.48%.Two-way communication can work well through WA, because WA is more familiar to be accessed anywhere, anytime. If the student is late to access every step of the weekly learning activity on the tutons, be reminded through WA. Progress of individual progress in completing discussions and tuton assignments informed through WA with the intent to motivate students to immediately follow the discussion and complete the tuton task. Thus it can be concluded that social media WA can support tuton activities.

Abstract

The study of “Pedagogical Content Knowledge Development of Science Prospective Teachers in Professional Practice Program” was conducted in one junior high school located in Bandung. The purpose of the study was to analyze the level and pattern of science prospective teachers’ PCK development as measured by CoRe. The study involved students who enrolled professionals practice program. Mixed methods, quantitative and qualitative research was utilized as a method in the study. Data collected by the coding and scoring of the CoRe instruments were analyzed  quantitatively; and data gained from observation, documentation, and interviews were analyzed qualitatively. The results showed that the PCK of prospective teachers are in the maturing PCK (level 3) and growing PCK (level 2). There are two patterns of PCK development showed by prospective teachers i.e. rising and fluctuative. The prospective teachers who are in the mature PCK show the pattern of rising, whereas prospective teachers who are in the growing PCK show fluctuative pattern. The study reveals that external and internal factors influenced the development of PCK. The pattern of guidance, lesson study activities, and intensity guidance are external factors that influenced the pattern of prospective students’ PCK development. Psychological effect that exists between teachers and students, the motivation of self to expand the horizons of knowledge, communication skills, and teaching experiences are the internal factors that influenced the development of prospective teacher PCK. The study suggests that the development of prospective teachers PCK in the program can be improved when supervisor and prospective teachers put consideration to those internal and external factors that influence the development of PCK.

Abstract

Learning media is a tool to convey messages or information aimed at instructional or contain learning purposes that can be manipulated, seen, heard, and read. Learning achievement is the result achieved after conducting learning activities. Both learning are done formally and non-formally which includes three aspects of student change cognitive, affective and psychomotor. The use of technology contributes greatly to the improvement of student achievement in English subjects, therefore students who use technology-based learning media in the teaching and learning process in the classroom will get good learning achievements. This research was conducted at SMK Nurul Muhtadin Kibin Serang, with a sample size of 32 students, from a population of 160 students, the researcher took 20% of the sample students from the total population of research. The method used in this research is quantitative descriptive method with research instruments: tests, questionnaires and literature studies. The conclusion obtained from this study is the effectiveness of the use of technology-based learning media in Nurul Muhtadin Vocational High School obtained mean value = 54 Median = 53.68 and Mode = 53.04 and SD = 5.16 While English Learning Achievement obtained mean = 79.53 Median = 77.5 Mode = 70 and Sd = 13.01 whereas from the results of the normality test L = 0.886 is thus Lo (0.2047)> of L (0.886). So that the null hypothesis (Ho) is rejected and the alternative hypothesis (Ha) is accepted, meaning that the sample is normally distributed. While the effect of the effectiveness of the use of technology-based learning media in SMK Nurul Muhtadin Kibin Serang, quantitatively it has a relationship that is sufficient or moderate, this is evidenced by the correlation coefficient ("r") of 0.60, the value is at intertval 0.60-0.80.

Abstract

Traditional Biotechnology Content as a Media in Engaging Students with System Thinking Skills. A study about how to engage students with System Thinking Skills as part of 21st century skills into Traditional Biotechnology content was conducted using Science-Technology-Religion-Engineering-Arts-Mathematics approach through one group pretest-posttest design. The study involved 43 students from 5th semester in one University determined purposively. Data were collected through system thinking test and interview format. After being collected through instruments mentioned before, data were then processed using percentage criterion n-gain on test and analyzed the result of student’s interview. Research results show 60.47% of n-gain (moderate) with the best achievement is in the ability to explain the function of each component, while the weakest achievement is in the ability to analyze the energy cycle. The result of the interview shows that the students are able to follow the lecture stages due to the repetitive and continuous assignment. The constraints found are in managing assignments within lecture time and less explored on religion aspects. Thus, Traditional Biotechnology content can facilitate students on system thinking skills.
