REDEFINING CRITERIA AND STANDARDS FOR COMPOSITION CLASSES

Abstract: Applying criteria in essay writing classes has been acknowledged as an important teaching and learning reference of evaluation; however, many students at lower level classes are experiencing difficulty in internalizing the conventional writing criteria and standards fully. As the result, many students produced insufficient pieces of composition and they continue depending on instructors to assess their work. In an attempt to address the situation, several criteria that students commonly encountered difficulties were redefined as supplementary writing criteria applied in planning and developing their essay compositions. Two projects writing of Argumentative essay in Writing 3 class were assigned, observed and evaluated throughout process writing approach, steps and activities. A survey of students’ attitudes was conducted and administered after completion of the second writing project. The results of study show an increase in student’s writing performance demonstrated after the course. Students' products of writing (N=20) were developed particularly on the organizational aspects. Students’ perceptions about the learning system were reported to be high. Some positive feedback and constructive comments were given for better future writing instructions.

Maximized The Young Language Learners’ Motivation Via Songs and Increasing Their Speaking Skill Ability

This article is aimed to describe the advantages of why songs are important to support the English language learning process. This article also explains the position where English is learned as the foreign language in Indonesia. Songs are learning resources with many advantages, including linguistics resources, affective/psychological resources, and cognitive resources. Songs can be good learning sources as teaching media for English language classes. As the world of children goes with songs and like to sing it. They love saying chants in rhythm and enjoy repeating phrases that rhyme. Moreover, they enjoy moving to the rhythm, clapping hands, tapping the feet, and dancing. Therefore, music and movement naturally connect to children's hearts, minds, and bodies. Teaching young learners has to be enjoyable for the classroom as young learners often use songs and movement to engage children in the class. Using songs and movement is one of the best ways to teach young learners. Making the learning process interesting for children is important, especially for young learners who learn English as a foreign language. Songs can also support the four skills for the learners such as speaking, reading, writing, and listening. Another language advantages are that pronunciation, vocabulary, and grammar are provided in learning through songs. It is such a duty for teachers to create a fun and enjoyable atmosphere in teaching. Using the textbook is no longer efficient for teaching young learners nowadays. The teacher tends to be more creative and tend to find more variation in delivering teaching materials, whether using songs from the internet, CD or tape recorder, or television. There are several benefits for language learning using songs for young English learners' classes. Music and songs can do the following: provided authentic, meaningful context, introduce children to the target culture, emotional and social effects, provide opportunities to practice oral language, Aid in retention and comprehension

Trial of Efficient Protein Expression Using Thermophilic Archaea as a Host

Thermostable enzymes of (hyper)thermophiles which exhibit optimal growth at temperatures above 55℃ have considerable potential for enzyme-based technologies as robust catalyst alternatives because most of them hardly unfold under various denaturing conditions. However, some thermostable proteins from hyperthermophiles often aggregate and form inclusion complex when they are expressed in mesophilic hosts such as Escherichia coli. A hyperthermophilic archaeon, Thermococcus kodakarensis grows fast and shows high cell density in nutrient medium and genetic technics including gene knockout and complementation by plasmid. T. kodakarensis contains a transcription repressor, SurR, which binds to the SurR-binding consensus sequence (SBS, GTTn3AAC) by causing conformational change in the absence of element sulfur (S0). S0 was expected as an inducer for the expression of interest of gene in an expression system in T. kodakarensis. The aim of this research is to construct an efficient protein expression system in T. kodakarensis cells as a host. To screen the suitable promoter in T. kodakarensis expression system, four promoters Tk0560, Tk1694, Tk2289 and Tk0895, have been chosen based on reported transcriptome analysis. Each DNA fragment containing the promoter region of these genes was cloned into Escherichia coli-T. kodakarensis shuttle plasmid pTKDR-His, yielding the plasmids pTKDR-pTk0560, pTKDR-pTk1694, pTKDR-pTk2289, and pTKDR-pTk0895 (designated as pCSG-His). Next, the T. kodakarensis DAD (∆pyrF, ∆pdaD) cell harboring each plasmid was separately cultivated anaerobically at 85˚C in nutrient-rich ASW-YT medium in the presence of S0. The cell extracts were applied to western blot analysis, performed by using antibody raised against Pc-Kat (Pyrobaculum calidifontis catalase gene as a reporter gene). The four candidate promoters contain a highly conserved 8-bp sequence element (TWTWTAWR, where W is A/T and R is A/C) and the purine-base-rich BRE (B recognition element), those of which are important for promoter strength. Among them, Tk0895 promoter led to the highest expression of Pc-Kat. To develop the switching system of expression in T. kodakarensis, SBS was tried to be inserted between TATA-Box and TSS in pCSG-His, but expected plasmid was not obtained. It is speculated that the high copy number SBS inserted in the plasmid has some toxic effect on E. coli cell growth. Each DNA fragment containing Tk0306 and Tk0460, which encodes RNA helicase, was cloned into the plasmid pCSG-His, yielding the plasmids pCSG-His-Tk0306 and pCSG-His-Tk0460, respectively. T. kodakarensis transformant harboring pCSG-His-Tk0306 or pCSG-His-Tk0460 were cultivated in ASW-YT media. Purification of the recombinant Tk0306 and Tk0460 proteins from cell extracts was performed using Ni-chelate affinity chromatography. The recombinant Tk0306 and Tk0460 were successfully obtained from T. kodakarensis extracts while Tk0460 showed smaller molecular mass than speculated size in SDS-PAGE, suggesting the recombinant Tk0460 was not fully denatured for SDS-PAGE in the present experimental conditions.

Morphology and polymorphism of TiO2 nanoparticles prepared in premixed stagnation flames

This thesis investigates the morphology and polymorphism of TiO$_2$ nanoparticles prepared in premixed stagnation flames in order to understand the factors controlling the formation of the particles. Computational models are developed and experimental measurements are performed to characterise the effect of varying process conditions on the particle properties. The model predictions and the experimental results are critically assessed to gain insights into the fundamental processes involved in particle formation. A univariate particle model is implemented in a flame solver to simulate TiO$_2$ particle formation from titanium tetraisopropoxide (TTIP) in a stagnation flame reactor. The particle model is solved using the method of moments with interpolative closure (MoMIC) and is fully coupled with the gas-phase chemistry and flow models. The model predictions are compared against literature data which reveals a good agreement for particle size but some discrepancy in particle geometric standard deviation (GSD). This suggests that the particle morphology is more complex that is assumed by the univariate particle model. The morphology of TiO$_2$ particles is characterised experimentally using transmission electron microscopy (TEM) image analysis and mobility measurements. The analysis allows a quantification of the particle sphericity. The detailed particle morphology is simulated using a post-processing method with a stochastic population balance solver. The model predictions show an excellent agreement with measurements for both particle size and GSD. The model is subsequently used to quantify the uncertainties in the measured particle morphology. The phase composition of the experimentally produced TiO$_2$ particles is analysed. The results demonstrate a high sensitivity of the phase composition to the premixed gas equivalence ratio, especially for near-stoichiometric mixtures. Metastable phases TiO$_2$-B and TiO$_2$-II are identified which provide new insights into the phase formation mechanism. It is suggested that TiO$_2$-II is a pre-rutile phase and it is formed through sub-oxide intermediates, TiO$_{2-x}$. The sensitivity of phase composition to the flame dilution is investigated experimentally for stoichiometric flames. The results demonstrate a strong influence of the flame dilution on anatase-rutile stability. Different hypotheses to explain the origin of this sensitivity are evaluated using the stochastic population balance solver with a size-dependent transformation model. The analysis suggests that the nascent particle composition may play a more important role in the anatase-rutile stability than the particle size.- Cambridge CARES studentship, Singapore National Research Foundation (NRF) - Departmental studentship (sponsored by CMCL Innovation) - Trinity-Henry Barlow Scholarship - CMEDT/MCSC Cambridge Bursar
