Communication Technologies

*Before the advent of computers and modern technology, people communicating over long distances used traditional means such as letters and the telephone. Nowadays, we have a vast array of communication tools that can complete this task, ranging from email to instant messaging and video calls. While the present and previous means of communication are similar in their general form, they differ in regard to their speed and the range of tools available.*

Similarities in Communication Forms

One similarity between current and previous methods of communication relates to the form of communication. In the past, both written forms, such as letters, were frequently used, in addition to oral forms, such as telephone calls. Similarly,...

Why Use Songs in Language Learning?

According to Blasi and Foley, children are inherently musical, which is supported by their eagerness to engage in musical play.

Neuman suggests that songs can improve children's memory, vocabulary, and creative uses of language.

Benefits of Using Songs for Language Learning

Fonseca notes that songs for language learning have been considered beneficial for:

• Developing the four language skills (reading, writing, listening, speaking)
• Activating both brain hemispheres
• Enhancing memory
• Increasing motivation
• Fostering cultural sensitivity

Additional benefits include:

• Songs provide a natural context for language use.
• Songs allow children to pick up chunks of language.
• Songs encourage all children to participate and speak in

Information and Communication Technology (ICT/IT)

Information and Communication Technology (ICT/IT) involves using computers to enable learners to improve information-processing skills and explore ideas. Examples include using Skype, surfing the internet, and solving problems.

Input and Output in Learning

• Input: All the material learners are exposed to. This is the knowledge someone acquires from outside by understanding it meaningfully.
• Output: What learners are able to produce using the acquired language or skills.

Input Hypothesis and Comprehensible Input

According to Stephen Krashen, we only acquire a language if we understand the input. The input cannot be beyond our current level of understanding (i+1).

This hypothesis was later modified: apart... Continue reading "Essential Terminology for Language Acquisition and Classroom Technology" »

Unit Commitment in Power Systems

Unit commitment is the process of selecting the generating units that will supply the load of a system over a period of time at minimum cost, as well as provide a specified margin of operating reserve. The total load on the system will generally be higher during the day and lower during the night. It is not economical to run all the available units all the time. The cost of the system can be saved by turning off units when they are not needed.

Need for Unit Commitment

• Enough units will be committed to supply the system load.
• To reduce loss or fuel cost.
• By running the most economic unit, the load can be supplied by the unit operating closer to its best efficiency.

Constraints in Unit Commitment

Constraints that must... Continue reading "Power System Unit Commitment Fundamentals" »

**Enhancing Bilingual Education: Connecting L1 and Target Language**

**The Interconnectedness of Languages**

The assumption that "students' languages should be kept separate" is incorrect because it overlooks the natural connections between a learner's first language (L1) and the target language (TL). It is impossible to completely separate these languages as they are interconnected in the brain. Therefore, teachers should actively promote this connection.

Lambert, Tucker, and Cummins emphasize the importance of extensive communicative interaction and comprehensible input in the TL. While creating separate spaces for each language is beneficial, it is equally crucial to establish a shared space that fosters language awareness and cross-language...
