The Importance of Teaching Reading: Improving Students' Reading Comprehension in Efl Context Emphasized on Reading Fluency and Accuracy
Current methods for teaching reading comprehension tend to emphasize the products of comprehension and neglect the processes of comprehension. Teachers often provide insufficient opportunities for learners to practice English in teaching reading. During teaching reading in a class teachers may confuse to give exercises relate to fluency or accuracy. The correlation between fluency and reading comprehension showed a significant positive relationship between oral reading fluency and reading comprehension performance. Therefore, automaticity of decoding fluency is essential for high levels of reading achievement. Assessing reading fluency, teachers need to listen to students read aloud to make judgments about their progress in reading fluency. In other side, teaching reading in accuracy exercises encourage a thoughtful use of language and the information is intended to help students understand how English works

Control and single-shot readout of an ion embedded in a nanophotonic cavity
Distributing entanglement over long distances using optical networks is an intriguing macroscopic quantum phenomenon with applications in quantum systems for advanced computing and secure communication. Building quantum networks requires scalable quantum light–matter interfaces based on atoms, ions or other optically addressable qubits. Solid-state emitters5, such as quantum dots and defects in diamond or silicon carbide , have emerged as promising candidates for such interfaces. So far, it has not been possible to scale up these systems, motivating the development of alternative platforms. A central challenge is identifying emitters that exhibit coherent optical and spin transitions while coupled to photonic cavities that enhance the light–matter interaction and channel emission into optical fibres. Rare-earth ions in crystals are known to have highly coherent 4f–4f optical and spin transitions suited to quantum storage and transduction, but only recently have single rare-earth ions been isolated and coupled to nanocavities. The crucial next steps towards using single rare-earth ions for quantum networks are realizing long spin coherence and single-shot readout in photonic resonators. Here we demonstrate spin initialization, coherent optical and spin manipulation, and high-fidelity single-shot optical readout of the hyperfine spin state of single ¹⁷¹Yb³⁺ ions coupled to a nanophotonic cavity fabricated in an yttrium orthovanadate host crystal. These ions have optical and spin transitions that are first-order insensitive to magnetic field fluctuations, enabling optical linewidths of less than one megahertz and spin coherence times exceeding thirty milliseconds for cavity-coupled ions, even at temperatures greater than one kelvin. The cavity-enhanced optical emission rate facilitates efficient spin initialization and single-shot readout with conditional fidelity greater than 95 per cent. These results showcase a solid-state platform based on single coherent rare-earth ions for the future quantum internet
CLASSIFICATION OF THE QUALITY OF HONEY USING THE SPECTROFOTOMETER AND MACHINE LEARNING SYSTEM BASED ON SINGLE BOARD COMPUTER
Honey is a natural sweet substance produced by bees with nectar flower ingredients containing various nutrients such as carbohydrates, proteins, amino acids, vitamins, minerals, plant pigments and aromatic components. Honey consists of water (17%), fructose (38.2%), glucose (31.3%), other disaccharides (5%), melezitose (<0.1%), erlose (0.8%) , other oligasakarida (3.6%), minerals (0.2%), amino acids (0.3%). It also contains anti-microbial substances, which can prevent some disease on human. Because it has a high economic value and contains unique substances, honey is often falsified. Honey can be faked in various ways by mixing natural artificial sweetener components or by giving the sugar (sucrose) into the honey, so it is dangerous if given to infants or people suffering from diabetes mellitus. The design of this research used spectrofotometer methode and pattern recognition algorithm (machine learning) system for classifying honey quality. It is based on honey having a chromophore group responsible for absorbance, electronic transition and color giver. We can also knowing the type of honey by using pattern recognition algorithm support vector machine.In this research is used three types of honey to using a spectrophotometer at a wavelength of 500 nm, the absorbance obtained in randu honey type of 0.523-0.654, coffee honey for 0.735-0.824, and rubber honey by 0.947-1.043

Arabic language education is very important starting from childhood because it is closely related to practicing religious law from an early age. The assumption is that Arabic is difficult because parents also do not master it. Because of this, it is necessary to develop a learning strategy by designing appropriate interactive illustrated books to help parents introduce Arabic vocabulary to children aged 6-8 years. The creative design objective is to introduce Arabic vocabulary by creating interactive illustrated books so that it is easier for parents to teach and attract children's interest in learning it. Interactivity in the book is in the form of pop-ups, lift a flap, and participation. The interactive illustration book was created based on the results of data analysis using the 5W+1H method obtained through questionnaires, literature studies, and interviews to answer the problem formulation. The results of the design are two books containing four stories with 44 nouns in Arabic. Pastel colors and cartoon illustration style are used in the design. The scriptwriting style uses narrative and descriptive styles. Meanwhile, the sans serif typeface is applied to the script based on the child's assessment that the typeface is easy to read.Keywords : Illustration, Illustrattion Book, Interactive, Vocabulary Arabic, Childre
