Patterns of Teaching-Learning Interaction in the EFL Classroom

The successfullness of teaching-learning process is highly influenced by the patterns of interactions appeared in the classroom activities. Through this case study, the purpose of this paper is to explore the patterns of interaction during teaching and learning proccess. Two accellerated classes were observed and recorded to gain the data. The findings revealed that the patterns of interaction emerged in the first class were group work, choral responses, closed-ended teacher questioning (IRF), individual work, student initiates-teacher answers, open-ended teacher questioning, and collaboration. Meanwhile, the patterns of interaction in the second class showed closed-ended teacher questioning (IRF), open-ended teacher questioning, choral responses, student initiates-teacher answers, group work, and individual work pattern. The patterns of interaction were produced from teacher and student(s) and/or student(s) and student(s) in relation to the teacher talk and the students talk categories used during learning activities. These patterns were produced constantly. They are to show that the teaching-learning process was not always dominated by the teacher. Most students actively participate as well in any classroom activity. Thus, these patterns absolutely increase the students talk and students' participation in the class. It is necessary for teachers to reorganize the active activities which might foster more interaction in the classroom

Protoplanet Dynamics in a Shear-Dominated Disk

The velocity dispersion, or eccentricity distribution, of protoplanets interacting with planetesimals is set by a balance between dynamical friction and viscous stirring. We calculate analytically the eccentricity distribution function of protoplanets embedded in a cold, shear-dominated planetesimal swarm. We find a distinctly non-Rayleigh distribution with a simple analytical form. The peak of the distribution lies much lower than the root-mean-squared value, indicating that while most of the bodies have similarly small eccentricities, a small subset of the population contains most of the thermal energy. We also measure the shear-dominated eccentricity distribution using numerical simulations. The numerical code treats each protoplanet explicitly and adds an additional force term to each body to represent the dynamical friction of the planetesimals. Without fitting any parameters, the eccentricity distribution of protoplanets in the N-body simulation agrees with the analytical results. This distribution function provides a useful tool for testing hybrid numerical simulations of late-stage planet formation.Comment: 8 pages, 2 figure

Blended-Learning: the Responses From Non-English Students in the Indonesian Tertiary Context

The process of language teaching and learning has undergone major changes due to the developments of technology. The use of technology in education field has paved the way for higher education institution to innovatively shape their modern media in a language teaching and learning. Subsequently, the implementation of blended-learning has aroused at the Universitas Teknokrat Indonesia for approximately one and a half year ago to maximize the use of technology. Most lecturers in all study programs have increasingly utilized the social network sites such as Instagram, Facebook, WhatsApp, etc. for the successfulness of blended-learning. This present study aims at exploring the students' responses on how blended-learning might be used to develop their language learning and discovering their attitudes towards the implementation of blended-learning as an interactional teaching and learning tool in English for Business course. Employing a qualitative in form of a case study, eighty-two undergraduate students from study program of Informatics Engineering were observed, interviewed, and distributed questionnaires. The data were performed to collect the students' responses and students' attitudes toward the implementation of blended-learning in the process of their language learning. The findings were found out that most students from Informatics Engineering major showed their positive responses and positive attitudes using blended learning for the language teaching and learning. They also gained some educational benefits for their English language development. Thus, this blended learning brings us to the new trend for language teaching and learning media in order to motivate the students in enhancing their language acquisition

The Self-Similarity of Shear-Dominated Viscous Stirring

We examine the growth of eccentricities of a population of particles with initially circular orbits around a central massive body. Successive encounters between pairs of particles increase the eccentricities in the disk on average. As long as the epicyclic motions of the particles are small compared to the shearing motion between Keplerian orbits, there is no preferred scale for the eccentricities. The simplification due to this self-similarity allows us to find an analytic form for the distribution function; full numerical integrations of a disk with 200 planetesimals verify our analytical self-similar distribution. The shape of this non-equilibrium profile is identical to the equilibrium profile of a shear-dominated population whose mutual excitations are balanced by dynamical friction or Epstein gas drag.Comment: 8 pages, 2 figure

An Exploration of Indonesian EFL Trainee Teachers’ Beliefs and Their Teaching Practice about Facilitating Learners’ Willingness to Communicate (WTC)

Abstract The main purpose of this research is to investigate the beliefs of trainee teachers regarding generating English language learners’ Willingness to Communicate (WTC), the relationship between their beliefs and practice and the influence of teaching practicum to their beliefs. This study took place in the Indonesian context in which EFL trainee teachers’ belief-practice relationships regarding learners’ WTC is still an understudied domain. Thus, this study was designed to fill this gap in current research. Three Indonesian EFL trainee teachers participated in this study during their teaching practicum. The study is within an Interpretive paradigm and utilizes a case study approach. Methods of data collection included classroom observation and semi-structured interviews. The findings showed that trainee teachers’ learning experience significantly influenced their beliefs and governed their teaching. Some of the trainee teachers’ beliefs were clearly manifested in their actual teaching (e.g. using explicit approaches particularly in teaching grammar). Other beliefs (e.g. creating interactive classroom activities) were not demonstrated. Several intrinsic factors such as trainee teachers’ English proficiency level and confidence, and extrinsic factors such as large class size and students’ responses were found to affect the relationship between trainee teachers’ beliefs and practice. Most of their beliefs (e.g. learners’ language knowledge as the key factor to communicate in English) remained unchanged after the practicum. Other beliefs, such as the need to use English and BI proportionally were not enacted in their teaching practice during the classroom observations. This study provides important implications for initial English language teacher education programmes, teacher professional development and for the field of teacher cognition and WTC

Photosynthesis is one of the physiological process that influence the bean weight and this process related with the efectiveness of the stomata character and chlorophyll content in the leaves. The research was conducted at Kaliwining Research Station, Indonesian Coffee and Cocoa Research Institute. Design of experiment was randomized complete block design (RCBD) consisted of six clones as treatment were Sulawesi 1, Sulawesi 2, Sca 6, ICS 60, TSH 858, ICCRI 03, PA 300. Each treatment was replicated three times. Stomata resistance diffusion, tranpiration,the content of chlorophyll a, chlorophyll b, chlorophyll total (a+b), bean number and bean weight were observed. The resuts of experiment showed that difference in chlorophyll a, chlorophyll b, chlorophyll total (a+b), stomata resistance diffusion, bean number and bean weight existed within six clones tested. Transpiration rate did not show the significantly different between six clones tested. Sulawesi 1 showed the highest content of chlorophyll a and ICS 60 and ICCRI 03 showed higher content of chlorophyll b than the other clones. Chlorophyll a, b and total (a+b) showed positively influence on bean number and bean weight. Transpiration rate had negatively influence to bean number per pod, on the otherhand it showed positively influence to bean weight. Chlorophyll total (a+b) showed high genetic variance (σg2), high phenotypic variance (σf2) and high estimated value of heritability (H). The chlorophyll a,b had moderate genetic variance, moderate phenotypic variance and high of estimated value of heritability. Chlorophyll total (a+b) could be used a selection criteria based on the value of correlation, genetic variance, phenotypic variance and estimated value of heritability would give high opportunity in selection process
