Understanding Signal Polarization

Signal polarization refers to the orientation of the electric and magnetic fields in space as an electromagnetic wave propagates.

Types of Electromagnetic Wave Polarization

Electromagnetic waves can exhibit different types of polarization, primarily categorized as linear or circular.

• Linear Polarizations: In linear polarization, the emitted signal maintains a constant orientation as it propagates. This type can be further differentiated into:
  • Vertical Polarization: The electric field oscillates along a vertical plane.
  • Horizontal Polarization: The electric field oscillates along a horizontal plane.
• Circular Polarizations: In circular polarization, the wave's electric field rotates as it moves through space. This means

Survey on English Studies Degree at University of Alicante

Demographics and Survey Objectives

From April 11th to 17th, 2016, a survey was conducted among 25 students. Of these participants, 72% were female and 28% were male.

Language Acquisition Theories

Imitation Theory

Children hear speech around them and copy it. When a child is raised in an English-speaking environment, they acquire English. Although, mistakes such as over-generalization ("goed" and "bes") are predictable and consistent.

Reinforcement Theory

Adults coach children when using language by praise and by correcting them. Parents may sometimes correct the truth of the statement rather than the form. The children's mistakes are often rule-governed (perhaps by always adding the suffix -ed to form past tense).

Active Construction of a Grammar Theory

Rules are hypothesized by the linguistic inputs recognized by children acquiring language. As children continuously receive language input, their language is... Continue reading "Language Acquisition: Theories and Stages of Development" »

Understanding ESP Course Design

Designing appropriate courses for diverse learner groups is a crucial teaching skill. While course design may be a minor part of a General English teacher's role, it is a substantial and vital component of the workload for an English for Specific Purposes (ESP) teacher. The process consists of asking critical questions to establish a reasoned basis for the subsequent processes of syllabus design. Key questions to address include:

• Why do the students need to learn?
• What do the students need to learn?
• Where will the learning take place?
• When will the learning take place?

It is important to approach terminology carefully. For instance, the term 'communicative' has become so emotive and open to multiple interpretations... Continue reading "Effective ESP Course Design Principles" »

**Listening: "Listen and Do"**

Listen and do activities require an action as a response. This allows you to immediately check if children understand or if they do not.

**1. Giving Instructions**

Some instructions that teachers can give to children in class are: "Okay, sit down, please," "Okay, everybody, stop talking now and listen carefully."

**2. Listening and Identifying**

When children do "listening and identifying" activities, they are practicing a basic language skill: listening, making sense of English words and phrases, and acquiring meaning and sound together.

For these activities, you can use the classroom and all the things the children can see, such as wall charts, pictures, or objects that children create.
