Notes, summaries, assignments, exams, and exercises for Electronics for Secondary education

• Automation: A set of elements that performs actions based on information from their sensors, without the intervention of a human.

• Robot: A programmable machine that can perform various tasks with mobile elements that follow trajectories previously drawn or decided by the robot based on data provided by onboard sensors.

• Control System: The component responsible for controlling and directing the actions of the robot. The electronic systems are complex and include one or more computers. By introducing computer programs, the actions of the robot are controlled.

WinLogo Technology Manual

Introduction

This unit aims to introduce faculty members to the use of computer technology and teach content and sequence control activities within the classroom.

Educational Objectives

This unit is intended to help teachers achieve the following objectives:

• 1. Analyze and decompose a complex problem into simpler components so that the initial problem is solved after addressing each part.
• 2. Use the appropriate methodology to implement the objectives set out in the preceding paragraph with students.
• 3. Use the LOGO programming language for the development of robotics and control algorithms.
• 4. Understand and utilize the controller as a connecting element between the machine and the computer.
• 5. Understand and utilize the interface

Unity and Variety in the Galician Language

Not everyone who speaks the same language does so in the same way. In Galician, there are differences in how people from one region speak compared to another. For instance, someone from Ourense (an 'auriense') might say a few words differently than someone from Fisterra (a 'fisterrán'), but this does not prevent them from understanding each other, because they speak the same language: Galician. These different ways of speaking a language throughout a territory are called geographic varieties or dialects. This variation exists because Galician is not yet fully standardized across the community of speakers and lacks a single, uniform standard. Linguistic variations can be represented on a map using isoglosses,...

Narrative Spaces and Their Characteristics

Spaces are the environments where the action takes place in a story; they are the frame where incidents occur involving certain characters. There are several types of spaces.

Classification by Extension

• Macro-space: The general setting where the story unfolds.
• Micro-space: Individual sites where an action occurs.

Classification by Reality

• Real: Specific, recognizable places or cities.
• Evoked: Created from an existing model.
• Imagined: When you reference models that do not exist.

Descriptive Viewpoints and Styles

We can take an objective or subjective viewpoint, or a general or detailed description. Descriptions can be written or formal, informal and oral. They can be found in informative and argumentative texts...

Narrative and Argumentative Text Types

Narrative: This is the representation of events that develop over time, presenting a logical and chronological order. Occasionally, that order is altered for aesthetic purposes.

Argumentation: This refers to texts that utilize evidence to convince a reader of a specific viewpoint or to affirm the validity of an opinion.

Properties of Textual Coherence

The statements forming a text are not an arbitrary list; they function based on intended meaning. A statement can provide information, zoom in, edit, or contrast previous points to achieve textual coherence. Key mechanisms include:

• Topic: The subject being discussed or written about must subordinate every sentence within the text.
• Presuppositions: Information the

Understanding Sound Waves

Sound is produced by the vibration of an object moving through an elastic medium. For humans, audible vibrations range from 20 Hz to 20,000 Hz.

Key Characteristics of Sound

• Amplitude: Determines the intensity or volume of a sound. Larger waves result in louder sounds, while smaller waves are softer.
• Pitch (Tone): Allows us to perceive sounds as acute (high) or serious (low).
• Timbre: Helps us distinguish between different voices or musical instruments.
• Infrasound: Frequencies below 20 Hz.
• Ultrasound: Frequencies above 20,000 Hz.

Wave Physics

• Period (T): The time taken to produce one complete cycle.
• Wavelength (λ): Calculated as λ = v / f, representing the distance a sound travels in one complete cycle.
• Frequency (f): The number

Teachers' Role in Classroom Technology

As computers are used more and more in education, there will soon be no role for teachers in the classroom.

Computers Improve Access and Engagement

There is no doubt that education and the learning process have changed since the introduction of computers: the search for information has become easier and more engaging, and connectivity has expedited data availability. Though expert systems have made computers more intelligent, they have not yet become a substitute for human interaction in the learning process. In my opinion, what can be expected is a change in the teachers' role, but not their disappearance from the classroom.

Nobody can argue with the fact that the acquisition of knowledge is more fun and...

Felicity Conditions in Communication

Let's analyze some examples:

• "Hi Joe, how are you?" - S wants to know A. H knows A.
• "Can you open the window?" - S wants H to do A. H is capable of doing A. S believes that H is willing to do A.
• "Mom, I am home." - S wants H to know A. H wants to know A.

Discourse and Language in Context

Discourse is language in context. It is given in a social context and involves interaction. Key factors include:

• Channel (S, W)
• Agent (mono, di, multi)
• Register (Formal, informal)
• Social context
• Purpose (transactional, interactional)
• Context (embedded, reduced)
• Genre (instructive, narrative, descriptive, persuasive, informative, expository)

Text form is the representation of text types.

Communicative Competences (M&S)

• Grammatical: Lexical

European Language Portfolio (ELP)

The European Language Portfolio (ELP) is a document designed for foreign language learners to record their learning journey and cultural experiences.

ELP Structure and Components

The ELP consists of three main parts:

• Language Passport: This section details an individual's foreign language proficiency level. It includes a table outlining skills (speaking, listening, reading, and writing), along with space for comments and certificates.
• Language Biography: A comprehensive record of an individual's language learning experiences, including certificates, diplomas, and courses.
• Dossier: Contains examples of personal work to illustrate achievements and experiences documented in the Language Biography and Passport.

Key Objectives

2 - the linguistic sign.-Linguistic signs are a type of signals used in the formation of messages in a language.

2.1. COMPONENTS OF SIGN LANGUAGE.-The signifier is specified in two dimensions. * Physical: the sounds we utter and transmitted through the air. * Psychic: the acoustic image we have of such sounds in our minds and allows us to recognize each of the sounds of the word. -The particular meaning in two dimensions: * Physics: The reality to which we apply the term. * Psychic: the concept, the mental image we have in the brain. Sounds and reality are material or physical components of the linguistic sign, while the acoustic image and concept are mental or psychological components. The linguistic sign is of a psychological nature.
