Tecnologia 9: Aula-Taller by Cristina Bonardi

Tecnologia 9: Aula-Taller is a book by Cristina Bonardi, a teacher and author of several textbooks on technology and science. The book is intended for students of the third year of secondary education in Argentina, and covers topics such as systems, processes, products, materials, energy, information and communication technologies, and environmental issues.

The book aims to provide a comprehensive and interdisciplinary approach to technology, using the systemic perspective as a guiding principle. The book also encourages students to develop critical thinking, creativity, problem-solving, and collaborative skills through various activities and projects.

The book is divided into six units, each with a central theme and several subtopics. The units are:

  • Unit 1: Systems and processes. This unit introduces the concept of system and its components, types, characteristics, and complexity. It also explains the different types of processes (physical, chemical, biological, social) and their phases (input, transformation, output).
  • Unit 2: Products and materials. This unit explores the concept of product and its functions, attributes, quality, and life cycle. It also analyzes the properties and classification of materials (natural and artificial), and their selection criteria for different products.
  • Unit 3: Energy and machines. This unit examines the concept of energy and its forms, sources, transformations, conservation, and efficiency. It also studies the concept of machine and its types (simple and complex), components (fixed and mobile), mechanisms (transmission and transformation), and functions.
  • Unit 4: Information and communication technologies. This unit investigates the concept of information and its characteristics, representation, transmission, processing, storage, and security. It also explores the concept of communication and its elements, types (verbal and non-verbal), modes (oral, written, graphic), media (analogical and digital), and devices.
  • Unit 5: Technology and society. This unit discusses the concept of technology and its historical evolution, social context, cultural diversity, ethical implications, and future challenges. It also evaluates the impact of technology on human development, quality of life, environment, economy, politics, education, health, and culture.
  • Unit 6: Technology and environment. This unit addresses the concept of environment and its components (biotic and abiotic), interactions (ecosystems), problems (pollution, degradation, depletion), and solutions (conservation, restoration, sustainability). It also proposes strategies for responsible consumption, waste management, renewable energy use, ecological design, and environmental education.

The book is available in PDF format for free download from Scribd. It has 40 pages and includes illustrations, diagrams, tables, charts, maps, photographs,
