Kind of Questions in Reading ComprehensionAccording to Loughed and TOEFL Information Bulletin in Djiwandono (2002:97), usually the questions in reading comprehension tests are about:. Main idea. Supporting details. Inferring meaning. Passage structure. Author’s aim. Knowledge about certain vocabulary.
Defining vocabulary based on the contextIn this study, the writer only concerns on main ideas and supporting details, because two kinds of reading comprehension test above are most important specific comprehension skills.a. Main IdeasThe question about main idea asks the reader to determine the main idea or topic from a reading text, and commonly it is signed by words such as: main point; mainly discussed; main idea; best title; main purpose; mainly concerned; main topic.Here are some examples of questions to ask about main idea:– What is the main idea of the passage?– With which of the following is the passage mainly concerned?– What is the main part of the passage?– Which of the following would be the best title?(Djiwandono, 2002: 98)b. Supporting DetailsThe question about supporting details asks the reader to find detail information that is printed explicitly in the text.
It is commonly signed by words such as: according to the author; according to the passage; who, what, when, where, why, how, which.Here are some examples of questions to ask about supporting details:– Which of the following question does the passage answer?– According to the passage, which statement is true?– When did ‘something’ happen?– Who did ‘something’?(Djiwandono, 2002:99)Filed under:,. Based on Brown’s (2001) explanation of display questions, schema theory and students’ background knowledge explanation. According to Harris and Sipay (1980:251) there are several cognitive factors in reading such as perception, attention, memory, and cognitive style.2.4.1 PerceptionPerception starts with the stimulation of sense organs such as the eyes and ears, but it is far more than simple sensing. In perceiving, the brain selects, groups, organizes, and sequences the sensory data so that people perceive meaningful experiences that can lead to appropriate responses.
Among the important characteristics of perception, several seem to have particular relevance for reading, such as follows:1. Figure and GroundNormally, one major unit or group of units is perceived clearly against a background that is more vaguely perceived.2. ClosureThe abilities to get the correct meaning of a sentence in which not all the words are recognized, and to pronounce a word correctly when some letters are blotted out, are examples of closure.1. SequenceIn reading, all the stimuli are on the page and sequence is imposed by the reader.2.
LearningPerception becomes meaningful units as they become associated with learned concepts and their verbal labels.3. SetOne’s immediate mind set provides an anticipation of what is likely to come that is helpful when the anticipation is correct, but leads to errors when the anticipation is incorrect.4. DiscriminationThe abilities to analyze a whole perception into its parts, and to synthesize the parts correctly are basic to success in visual and auditory discrimination of words.2.4.2 MemoryPsychologists distinguish between iconic memory, the fraction of a second that a sensory impression lasts before it fades out. Short term memory, which lasts a view second and long term memory. Reading ComprehensionIt is necessary for the students of Senior High School to master reading comprehension.
Cooper (1986:11) stated that Comprehension is a process in which the reader may construct meaning by interacting with the text. In reading comprehension, a reader should have knowledge about understanding the reading passage.
The common questions on the passages are primarily about the main ideas, details, and an inference that can be drawn from the passages.According to Singer (1985) reading comprehension has been defined as an interpretation of written symbols, the apprehending of meaning, the assimilation of ideas presented by the written, and the process of thinking while deciphering symbols. Further, reading comprehension is related closely to the cognitive competence of the readers, because this will produce comprehension. This idea also supported by Parera in Kahayanto (2005:9), he states as follows:“Memahami adalah memperhatikan naskah tertulis dengan maksud memahami isinya.
Proses ini dilakukan dengan mata diam atau membaca dalam hati. Hasil pemahaman disebut pemahaman bacaan.
Cara membaca yang demikian disebut cara membaca pemahaman”.In comprehending a topic, the readers interacts with the text relates to the pre-questioning of the text to prior experiences of construct meaning which can be found in the text. Skimming and scanning are two very useful techniques that will help the reader become a better reader. 1. SkimmingSkimming is a technique used to look for the “gist” of what the author is saying without a lot of detail (Kustaryo, 1988:5).
This reading technique is used if one wants to get a general impression of a book, essay, article and determine whether or not to read it more carefully. Moreover, Yorkey (134) defines that there are two purposes of skimming: to locate a specific word, fact, or idea quickly, and to get a rapid general impression of the material.
Azies & Alwasilah (1996:114) said “Aktifitas skimming melibatkan proses membaca, sekalipun dengan kecepatan melebihi kecepatan membaca pada umumnya”.Thus, in skimming the text, a reader needs to practice in order he or she can learn the key words and phrases which can cover all the material he or she is reading. To do the skimming, the reader should go through a passage quickly, jumping over parts of it, in order to get a general idea of what it is about.

2. ScanningScanning is quickly reading to find the specific information Brown (2001:308) stated that, scanning is quickly searching for some particular piece or pieces of information in a text.By scanning, a reader mean glancing rapidly through a text either a text either to search a specific piece of information (e.g. Name, date) or to get an initial impression of whether the text is suitable for a given purpose”, Nuttall in Kahayanto (2005:11). When scanning the reader lets his or her eyes wander over the text until he or she is looking for, whether it is a place, a kind of food, a kind of verb, or a specific information. To enable the student to scan effectively, he or she should know what kinds of information he or she needs, also, he or she should have the strong belief where he or she will find such information needed from the text.Filed under:.
There are four skills in English which should be mastered, they are: reading, speaking, listening and writing and it cannot be denied that reading is one of the most important. According to Harmer in The Practice of English Language Testing (1985:153) “Reading is an exercise dominated by the eyes and the brain”. Specifically, Nunan (1989:17) in his book also said that “Reading is a process of decoding written symbols, working from smaller units (individual letters) to larges ones (words, clauses and sentences)”.Based on explanation above, the writer concludes that reading is a process to convey the message or information.
By reading, the reader will know what they read and challenged to response the ideas of the author. In order to make the messages or information that comes from the author can be understood and comprehended easily by the reader.Filed under:. 9Sebagai ilustrasi untuk persamaan non-linear berderajat lebih dari dua dapat dikatakan mempunyai penyelesaian yang tidak mudah bahkan dan tidak mungkin diselesaikan secara analitik. Tetapi bukan berarti persamaan tersebut tidak mempunyai penyelesaian, hanya saja menyelesaikan persamaan semacam itu sangat sulit dan kalaupun bisa memerlukan pengetahuan matematis yang tinggi dan waktu yang cukup lama. Dengan dasar inilah dapat dikatakan bahwa diperlukan suatu metode tertentu yang dapat digunakan untuk menghitung persamaan tersebut.
Meskipun metode tersebut tidak dapat menghasilkan nilai yang exact (tepat), setidak-tidaknya sudah mendekati nilai yang diharapkan. (Amang, 2006: 1)Penyelesaian persamaan non-linear adalah penentuan akar-akar persamaan non-linear.
Dimana akar sebuah persamaan f(x) = 0 adalah nilai-nilai x yang menyebabkan nilai f(x) sama dengan nol. Dengan kata lain akar persamaan f(x) adalah titik potong antara kurva f(x) dengan garis y = 0.Filed under:.
Latar BelakangPersoalan yang melibatkan model matematika banyak muncul dalam berbagai disiplin ilmu pengetahuan, seperti dalam bidang fisika, kimia, ekonomi, atau pada persoalan rekayasa (engineering), seperti Teknik Sipil, Teknik Mesin, Elektro dan sebagainya. Seringkali model matematika tersebut muncul dalam bentuk yang tidak ideal atau sulit untuk dikerjakan secara analitik untuk mendapatkan solusi sejatinya ( exact solution). Yang dimaksud dengan metode analitik adalah metode penyelesaian model matematika dengan rumus-rumus aljabar yang sudah baku atau lazim digunakan.Sebagai ilustrasi, diberikan beberapa contoh berikut ini:. Penyelesaian akar-akar persamaan polinom:23,4x 7 – 1,25x 6 + 120x 4 + 15x 3 – 120x 2 – x + 100 = 0. Pencarian harga x yang memenuhi persamaan:. Penyelesaian sistem persamaaan linear:1,2a – 3b – 12c + 12d + 4,8e – 5,5f + 100g = 180,9a + 3b – c + 16d + 8e – 5f – 10g = 174,6a + 3b – 6c – 2d + 4e + 6,5f – 13g = 19.
