What Is an Educational Program?

An educational program is an official, national, or regional document that outlines the set of objectives, content, and other elements to be developed for a specific educational level.

In that sense, according to Zabalza (1997), the program is the set of official teaching requirements issued by a central authority.

The program collects what is defined at any given cultural and social moment as the common and shared knowledge, skills, values, and experiences of a people. As it is presented in prescriptive terms, we refer to it as the set of learning experiences that all children in a school system must undergo.

The program includes the common minimums for the entire society, representing the shared structure of a... Continue reading "The Role and Functions of an Educational Program" »

In the study of linguistics, we often encounter assumptions about language validity. These assumptions are not sustained merely through arguments, but must be rigorously tested and proven or disproven through empirical research.

Arbitrariness

Language maintains only a conventional relationship with the reality to which it refers. The link between the signifier (sound/form) and the signified (meaning) is not natural or necessary. This concept has three main aspects:

• Signifier-Signified Relationship: There is no inherent link between the word chair and the object it represents.
• Phonological Distinction: The fact that Spanish may have lost the distinction between long and short vowels (unlike some other languages) does not alter the core meaning of

Understanding Prescriptive Language

Prescriptive language is a type of discourse that aims to guide or regulate the behavior of the recipient in the development of an activity or task.

Types of Prescriptive Texts

• Regulatory Texts: These collect orders or rules by which the issuer intends to govern behavior. Examples include laws, regulations, and codes of conduct.
• Instructional Texts: These provide tips or instructions for the receiver to perform a task. Examples include recipes, manuals, and how-to guides.

Structure of Prescriptive Language

The structure of prescriptive language typically includes:

• Goal

  This serves as the title and sometimes includes an initial explanation in the first paragraph, outlining the objective of the prescriptive text.

• Program

Instructional Texts: Guiding Future Actions

Instructional texts aim to teach the receiver how to regulate their conduct in the future, effectively directing, teaching, arranging, or advising them on performing actions.

Structure of Instructional Texts

• Objective: The purpose of the text, often brief and summarized in the title.
• Instructions: Steps presented in a logical (cause-effect) or chronological order, detailing orders, advice, or actions. Ideas are typically organized into paragraphs, each addressing a single topic or subtopic. Instructions may also be grouped into sections or subsections.

Linguistic Characteristics of Instructional Texts

• Verbal Forms: Frequent use of conative verbal forms or appeals (e.g., must do, has to do).
• Person: Use of

Mastering Textual Properties for Effective Communication

Communicative Adaptation: Linguistic Diversity and Registers

Communicative adaptation requires the knowledge and mastery of linguistic diversity. Language is neither uniform nor homogeneous. Speakers and writers must choose the appropriate dialect form and register for their context.

Criteria for Text Suitability

To check whether a text is suitable, the following criteria must be met:

• Achieves its intended goal.
• Appropriate personal treatment (tone).
• Level of formality maintained consistently throughout the text.
• Maintenance of the required degree of specificity.

Consistency (Coherence): Processing and Structuring Information

Coherence is the domain of information processing. It dictates what information... Continue reading "Mastering Textual Properties: Cohesion, Coherence, and Adaptation" »

Linguistic Registers and Stylistic Varieties

Stylistic varieties, or registers, refer to the way a speaker uses a language depending on the communicative situation. This is influenced by the relationship between the sender and receiver, the channel, the topic, the purpose, the time, and the place. There are two main types of registers:

• Formal Register: Used when the relationship between participants is distant. It is characterized by respect for established grammatical rules and a sophisticated use of language.
• Informal Register: Used in familiar and friendly settings. It typically occurs in spontaneous, everyday situations and is a practical language, aiming for concrete and immediate communication.

Scientific and Journalistic Texts: A Comparison

Scientific Texts

Scientific texts encompass research reports, studies, and scientific expertise. The primary objectives are to present accurate, clear, and demonstrable statements of fact.

General Characteristics:

• Clear and logical management of information
• Objectivity
• True and verifiable conclusions
• Brief paragraphs
• Support from graphics and artificial languages

Linguistic Features:

• Denotative lexicon
• Monosemic words
• Use of jargon
• Concrete nouns
• Use of the present indicative tense
• Specified adjectives
• Reflexive passives
• Impersonal sentences
• Declarative sentences

Structure:

Scientific texts employ exposition and description. Exposition explains and clarifies concepts, while description presents the characteristics... Continue reading "Understanding Scientific and Journalistic Texts: Key Features" »

Adjectival Subordinate Clauses

Adjectival subordinate clauses are propositions whose function is equivalent to that of adjectives in simple sentences, usually serving as a nominal complement to which they refer.

Types of Adjectival Clauses

• Specify: These form a single phonetic group with the noun they relate to and limit its field of application.
• Explanatory: Framed between two pauses, these express a characteristic or provide clarification.

Key Characteristics of Adjectival Clauses

1. The relative pronoun "which" can be confused with the conjunction "that". To distinguish them, try replacing "which" with "that" (or vice versa). If the change is grammatically acceptable, it is likely a subordinate adjective clause.
2. An adjectival clause almost always

Elements of Communication

The elements involved in an act of communication are:

• Sender: Produces the message and sends it.
• Receiver: Receives the message and interprets it.
• Code: A set of signs and rules that the sender and the receiver know and use to encode and decode the message.
• Message: The statement sent by the sender and received by the receiver.
• Channel: The physical environment or medium through which the message travels.
• Context: The circumstances (psychological, social, emotional, etc.) surrounding the sender and receiver, which influence the message's transmission and reception.
• Referent: The real-world element or situation to which the sender's message refers.
• Noise: Any interference affecting any of the other elements, which causes the
