TEST ITEM ANALYSIS OF READING COMPREHENSION EXAMINATION FACULTY OF TEACHERS AND TRAINING EDUCATION
Authors: Lumban Raja Viator 
Published: October 2021

It is not uncommon to put a blame on the students when they fail in the semester examination. The examiner or the one who constructs the test is rarely blamed or questioned why such a thing can happen. There is never a question whether the test is valid or reliable. In other words, the test itself is never evaluated in order to know if it meets the level of difficulty and power of discrimination. Madsen (1983: 180) says that item analysis tells us three things: (1) how difficult each item is, (2)whether or not the question discriminated or tells the difference between high and low students, (3) which distracters are working as they should. Â This reading comprehension examination consists of 44 items, 35 items of reading comprehension and 9 items of vocabulary. The number of test takers are 18 students. The result of the analysis shows that only 5 students (27.7%) can do the test within average, meaning they can answer the test 50% correct of the total test items. This belongs to moderate category, not high nor excellent. Of the 44 test items, 33(75%) are bad items in that they do not fulfill one or both of the requirements concerning the level of difficulty and power of discrimination. And only 11 items (25%) meet the requirements of level of difficulty and power of discrimination. Regarding the distracters, there are 20 items (45.45%) whose distracters are not chosen either one or two. There are two items (4.54%), 25 and 34, the correct answer of which is not chosen by the test takers, including the high and low group. In short, these 20 items needs revising in term of distracters. Revision is made to those items whose distracters are not chosen and those which do not fulfill the requirements of level of difficulty and power of discrimination. Distracters which look too easy are changed, and those which are not totally chosen are revised.Â
THE FRESHMENâ€™S ABILITY ON USING THE GRAMMAR OF ENGLISH IN ACADEMIC YEAR 2019/2020
Authors: Lumban Raja Viator 
Published: October 2021

Grammar is the rules of how words are arranged into sentences. Without the knowledge of grammar one cannot produce sentences grammatically. If one makes a sentence whichÂ is not grammatically arranged, then that sentence cannot be said grammatical though perhaps it is still meaningful. Therefore, a sentenceÂ shouldÂ be grammatically correct and meaningfully acceptable. This study deals with the ability of the freshmen of the English Study Program on using English grammar in academic year 2019/2020. They are first given the pretest, and after studying for one semester they are given the posttest in order to see if there is significant difference from the pretest to posttest. It is expected that the learning-teaching process for one semester will give significant impact on the learning achievement. Based on the result of analysis of the test both in the pretest and posttest, it is found out that there found no difference between the result of the pretest and that of posttest. It is indicated by the mean score of the pretest 9.04 and that of posttest only 9.00. Therefore, it can be concluded that their ability on using English grammar is far below the average as the percentage of correct answer only 30.10% both in the pretest and posttest. Â Of the 17 topics covering the 30 test items both in the pretest and posttest, only 5 (five) items are correctly answered by more than 10 students within the percentage of 44% - 68%. On the whole,. Their ability on using English grammar is far below average.

Published: October 2021

The aims of this study were to figure out the casual factors of ambiguity found in students writing. The subject of this study was the students of Class XI-TKR of SMK Dharma Bakti Medan. The research design was in the form of descriptive qualitative research. The instrument of collecting data was the studentsâ€™ sheet of English writing text. In conclusion, the most dominant ambiguity in lexical meaning found in writing text by Class XI-TKR of SMK Dharma Bakti Medan was polysemy ambiguity. There were 10 casual factors of why ambiguity found in studentsâ€™ writing text based on the analysis of the structure of sentence in studentsâ€™ English writing. The most reasons were: (1) the students did not give the specific details in their writing, usually they preferred the short writing, (2) there were several vocabularies which could be reasonably interpreted more than one way or reasonably interpretedÂ moreÂ thanÂ oneÂ thing,Â (3)Â theÂ studentsÂ feltÂ confusedÂ toÂ findÂ appropriate vocabularies to express the meaning. As a result, they sometimes left the sentence undone or hanged without a clear idea, due to the lack of vocabularies. The analysis of ambiguity in lexicalÂ meaningÂ thatÂ made byÂ studentsÂ of ClassÂ XI-TKRÂ of SMKÂ DharmaÂ BaktiÂ Medan revealedÂ thatÂ studentsÂ shouldÂ learnÂ semanticÂ asÂ theÂ mainÂ subjectÂ inÂ EnglishÂ writingÂ to understand multiplicity of meanings.
Effectiveness of Blended Approach in Teaching and Learning of Language Skills in Saudi Context: A Case Study
Authors: Ahmad Jameel 
Published: October 2021

The blended approach serves as an effective interface between web-based and face-to-face teaching and learning of language skills. It offers the best of both and commoditizes broad-based teaching and learning avenues thereby bringing the whole teaching and learning process to life. An empirical study conducted on EFL/ESP teachers and learners of Saudi universities indicates that adopting a fully online or a fully offline approach is not as effective as a blended approach. The overwhelming majority of the respondents illustrate that a blended approach offers a rich variety of alternatives combining both online and offline platforms. It is also evident from the findings of the current study that even a technophobic teacher of the old generation can enrich his pedagogical effectiveness while navigating and integrating a vast variety of authentic online resources in his face-to-face teaching. Nevertheless, a learner can also learn language skills effectively by interacting with the dynamic instructors in a face-to-face environment and by repeatedly using online audio-video learning resources at his convenient time. In fact, modern learners are becoming more tech-savvy owing to an exponential growth of Internet usage during the current pandemic of COVID-19, and hence willing to embrace digital learning to enhance their learning experiences. So, let both get intertwined and go hand in hand to revitalize both teaching and learning activities. The amalgamation of the interactive dynamic environment of offline and individualized/independent learning online offers a rounded learning experience.

insígnia, escafandro, sátira e locus: análise de processos criativos em comprovisação
Authors: Faraco Arthur 
Published: October 2021

Nosso objeto de análise neste artigo é o conjunto de peças insígnia, escafandro, sátira e locus, criadas pelo autor. Estas são consideradas como experimentos em comprovisação, devido às características de seus processos criativos. Comprovisação, como um termo recente na literatura, não há até o momento um consenso; por isto, reunimos aqui possíveis antecedentes, as noções sobre e práticas que buscam na comprovisação sua caracterização. Distinguimos duas vertentes teóricas sobre o assunto, e realizamos considerações próprias almejando uma compreensão do termo a partir de uma interligação os fluxos de interpretação e improvisação – estes vinculados a noções de processos generativos da performance e da compreensão de Falleiros (2012) sobre o pacto. Por meio de ferramentas tradicionais de análise, e da perspectiva notacional de Bhagwati (2013), acreditamos que a ressignificação dos gestos improvisados existentes nas peças analisadas aponta para a compreensão destas como experimentos em comprovisação.
