Understanding Elision in English Phonetics

Elision is the linguistic process by which a phoneme is dropped from a word during speech.

Elision of T and D

This kind of elision can be found in a good number of cluster combinations, but is particularly common in ft, st, ld, and nd. Examples include:

• Postcard
• Left shoe
• Old man
• Stand here

However, elision is not possible in the following cases:

• Left ear: because the 't' is followed by a vowel.
• First hand: because the 't' is followed by 'h'.
• Paintbox: because the 't' is preceded by a voiced consonant.

In the conjunction "and," the final 'd' may be elided. For example: black and white. Contractions ending in n't (such as don't, doesn't, didn't, and can't) may drop the 't', with the exceptions of wasn't and weren'

Outlet: A store selling goods of a company, usually at a lower price.

Outcome: The result or effect of an action, situation, or event.

Outlook: The likely future situation.

Outing: A short journey made by a group of people.

Onset: A start; a beginning.

Outrage: A strong feeling of shock.

Outbreak: A sudden appearance of a disease.

Outlay: An amount spent at the beginning of a business.

Idioms and Expressions

Break the mould: To be new and different.

Blind someone with science: To confuse somebody by using difficult or technical words.

Move with the times: To change and become more modern because attitudes and fashion are changing.

Be someone's guinea pig: To be the subject of an experiment.

Turn the clock back: To want to return to a past situation because... Continue reading "Essential Vocabulary: Definitions for Modern Concepts" »

Learning and Teaching Concepts

Understanding Learning Styles

Visual Learners: Characteristics and Benefits

• Will have very good visual memory and be able to visualize remembered scenes, objects, or faces years later.
• Will enjoy and benefit from visually presented information such as graphs, posters, maps, and more.
• Will utilize a visual spelling strategy and thus "see" words and their constituent shapes as they spell them.
• Will look upwards when accessing remembered information.
• Will use visual predicates: "I see what you mean," "just imagine," and similar phrases.

The Role of Motivation in Learning

Defining Motivation

Motivation has traditionally been used to describe and explain differences in the intensity and direction of behavior. It is the state... Continue reading "Effective Learning: Styles, Motivation, and CLIL in Education" »

Defining the Teaching Approach

An approach is, by definition, dynamic and therefore subject to tinkering as a result of one’s observation and experience.

Research in second language acquisition and pedagogy almost always yields findings that are not conclusive but are subject to interpretation.

Communicative Language Teaching (CLT)

Historical Development

• 1940s & 1950s: The foundational period.
• 1960s: Chomsky’s generative grammar was considered for language classrooms, focusing on how to inject the "cognitive code" of a language into the process of absorption.
• 1970s & 1980s: The beginnings of what we now recognize as a communicative approach emerged.
• 1980s & 1990s: This era saw the development of approaches that highlighted the communicative

Keeping Fit

A single-phase transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction. It consists of two coils, known as the primary and secondary coils, wound around a common magnetic core. The primary coil is connected to the input voltage source, while the secondary coil is connected to the load.

Basic Principles of Single-Phase Transformer Operation

Faraday's Law of Electromagnetic Induction

When the primary coil is energized with an alternating current (AC), it creates a changing magnetic field around the coil. According to Faraday's Law of Electromagnetic Induction, this changing magnetic field induces an electromotive force (EMF) in the secondary coil. The induced voltage in the secondary...

Understanding the Learning Cycle

The learning cycle is the process of acquiring information. It begins at birth and continues throughout life.

How We Learn

We learn from others or by ourselves. We learn through trial and error. Thus, we learn from our outside environment. For example:

• Watching parents doing things.
• Listening to teachers at school and college.
• Watching television.
• Listening to religious scholars.
• Reading books and newspapers.

Interpreting Words

Language is a powerful means of communication, conveyed through words. For example:

• A word can have several meanings, such as ‘ways’.
• Words have different meanings in different parts of the world, like ‘Dalla’ or ‘Calendar’.
• Meanings change over time, for instance, ‘sandwich’ or ‘diesel’.

Alternating Current and RMS Values

• RMS value means: Peak value divided by 1.41.
• The effective RMS is: Smaller than the peak value.
• An effective RMS value circuit of 10: Results in 14.14.
• Measuring voltage with AC voltmeters: Displays the effective value.
• The AC curve can be present: It decreases from 1 to 0.
• Instant value of AC power: The value at a specific time of the cycle.

AC Motors and Alternators

• Single phase alternator: Stator windings connect in series.
• Types of AC motors: Synchronous and induction motors.
• AC motors speed is relative to: The number of poles and frequency.
• Shaded poles: These facilitate starting.
• Three-phase synchro has: 3 stator and 1 rotor windings.

Circuit Components and Filters

• Electronic circuit designed as a Band pass filter:
