Interlanguage: A Unique Linguistic System

Interlanguage recognizes that L2 learners construct a linguistic system that draws, in part, on the learner’s L1 but is also different from it and also from the target language. It is a unique linguistic system and involves different premises.

Premises of the Interlanguage System

1. Mental Grammar: The learner constructs a system of abstract linguistic rules which underlies comprehension and production of the L2. This system is viewed as a mental grammar.
2. Permeability: The learner’s grammar is permeable. It is open to influence from the outside (e.g., through the input) and also from the inside (omission, overgeneralization, and transfer errors).
3. Transitional Nature: The grammar is transitional. Learners

!!PHY 2!! VARIABLES: P_r = Receiving power (W/mW) P_T = Sending power (W/ mW) G_T = Sending antenna gain G_R = Receiving Antenna Gain H_T = Sending antenna height (m) H_R = Receiving Antenna height (m) d = transmission distance (m) λ = c/f = wavelength (m) f = frequency (Hz) c = Speed of light = 3 * 10^8 (m/s) d_break = break point distance (m) N_T = number of transmitting antennas N_R = number of receiving antennas v = velocity (m/s)
Free space Path Loss (Friis Equation): P_R = P_T * G_T * G_R * (λ / (4πd))^2 unit antenna gain is 1. (IF isotropic antenna (theory) P_R = P_T * (c / (4πdf))^2 )

English Language Levels and Learning Activities

When planning activities, we must consider the students' English level, with the help of the course materials and their textbooks.

First and Second Year Students

• Encourage the use of adjectives, nouns, and general vocabulary in phrases and longer sentences.
• Writing is very limited at this stage.
• Activities: Circle, draw, match, associate.

Third and Fourth Grade Students

• Encourage greater independence.
• Activities: Complete sentences, fill in the blanks, answer questions, short writing tasks.

Fifth and Sixth Grade Students

• Expect them to develop critical thinking and use a variety of adjectives, nouns, and verbs.
• Activities: Write paragraphs, descriptive writing, opinion pieces, compare and contrast, summarize

Explicit: the direct

Implicit: the hidden

Key Elements to Analyze:

Purpose: main goal (principal idea) of the text or speech

Tone: formal, informal, persuasive, neutral (how it makes you feel)

Audience: people who listen/read.

Cultural Context: where the action happens.

Oral Discourse: verbal communication, such as conversation, presentation, or debate.

Written Discourse: communication through texts, such as articles, emails, or books.

Interculturality: the interaction and exchange between people of different cultures, recognizing and respecting their differences.

Cultural Sensitivity: the ability to understand and appreciate cultural differences, avoiding judgments based on one's culture and showing respect for others.

Key Linguistic Tools:

Opinion Expressions:

Essential Vocabulary for Early Childhood Learning

Understanding key terminology is crucial for discussing educational methods and child development.

Glossary of Educational Terms

Awareness

Knowledge that the human being has of his own existence, of his states, and of his acts.

Blank

Not knowing how to react; a state of mental emptiness.

Board

A long rectangular piece of slate or material used for drawing or explaining concepts.

Communication

Transmission of signals by means of a code common to the transmitter and the receiver.

Dice

A small object, typically cubical, used in games like Parcheesi, marked with one to six dots on each face.

Elicit

To get or draw out something that is wanted, requested, or deserved.

Fine Motor

The coordination of small muscles

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...

History

18th and 19th centuries: faculty psychology approach.
Mental discipline was considered essential for strengthening the powers of the mind.

In the nineteenth century the classical method came to be known as the grammar–translation method.

In Western schools, learning a foreign language meant learning Latin or Greek.

Main objective: Help students to read and appreciate foreign-language literature, gaining reading proficiency.

Understanding Spooling in Operating Systems

Spooling (Simultaneous Peripheral Operations Online) is a technique used in operating systems to manage I/O operations efficiently. It involves buffering data for various I/O devices, such as printers, in a temporary storage area (usually disk).

• Input Spooling: This technique involves reading jobs (for example, from cards) onto the disk. This ensures that when currently executing processes are finished, work will be waiting for the CPU, maximizing CPU utilization.
• Output Spooling: This consists of first copying printable files to disk before printing them, rather than printing directly as the output is generated. This frees up the CPU and application to perform other tasks while printing occurs in the

Oral Communication

In oral communication, the most important element is the channel (the spoken word). It involves two interlocutors: the sender and the receiver.

Types of Oral Communication

• Face-to-face: Non-verbal aspects are crucial.
• Distance communication: Active listening and empathy are important.

Requirements: Analyze the situation and prevent barriers.

Features of Oral Communication

1. Sender: Transmits credibility and capability; uses a rich vocabulary and resources.
2. Receiver: Listens properly and provides feedback.
3. Message: Clear, neat, accurate, objective, and relevant.
4. Context: The message must be adapted to the receiver.

Advantages

• Speed.
• Supported by non-verbal elements.
• Provides immediate feedback.

Disadvantages

• The message must be understood immediately.

Present Simple

Describes habitual actions, facts, and general truths.

Formulas:

• (+) Affirmative: Subject + Base Verb (+s/es for he/she/it) + Complement
  • Example: I play tennis. She cooks dinner.
• (-) Negative: Subject + do/does + not + Base Verb + Complement
  • Example: I don't play tennis. She doesn't cook dinner.
  • Note: The 's' is not added to the verb when 'does' is used.
• (?) Interrogative: Do/Does + Subject + Base Verb + Complement?
  • Example: Do I play tennis? Does she cook dinner?

Present Continuous

Describes actions happening now or around the present moment.

Formulas:

• (+) Affirmative: Subject + Verb to be (is/are/am) + Gerund (-ing) + Complement
  • Example: We are writing in English class.
• (-) Negative: Subject + Verb to be (is/are/am) + not + Gerund (-ing)
