Understanding Needs Assessment in Curriculum Development

The assessment of needs is a critical and complex issue, which comprises the most significant component of the curriculum development process. Teachers should play a pivotal role in this process if effective learning is ever going to take place.

These assessments of needs should be done with reference to the four P’s: Problem, People, Place, and Performance.

Roger Kaufman is known as the “Father of Needs Assessment”.

Five Basic Assumptions of This Model

  1. Curriculum and instruction (instructional design)

Understanding Communication: Elements, Codes, and Functions

Elements of Communication

  • Referent: The factual or conceptual material on which the message is based.

RAM Technology: DRAM vs. SRAM

RAM technology is divided into two primary types:

  • Dynamic RAM (DRAM)
  • Static RAM (SRAM)

DRAM

  • Made with cells that store data as a charge on capacitors.
  • The presence or absence of charge in a capacitor is interpreted as a binary 1 or 0.
  • Requires periodic charge refreshing to maintain data storage.
  • The term *dynamic* refers to the tendency of the stored charge to leak away, even with power continuously applied.

DRAM vs. SRAM: Key Differences

  • Both are volatile, meaning power must

802.11 WLAN Topologies, Antennas, and Protocols

WLAN Topologies

802.11 LAN Topologies:

  • Ad hoc: Direct device-to-device communication.
  • Infrastructure: Uses an Access Point (AP).

Key Terms:

  • BSS: Basic Service Set.
  • IBSS: Independent Basic Service Set (no AP).

Network Setup:

  • Devices communicate without an AP by defining a group name.
  • In infrastructure mode, an AP acts as a bridge connecting wireless clients to a wired network.
  • Wireless clients are also known as stations.
  • An AP is an infrastructure device.
  • The coverage area of a single AP is called a BSA.
  • Multiple

Oral vs Written Communication: Key Differences & Analysis

Linguistic Skills: Oral vs. Written Communication

ITEM 5. (Listening). LINGUISTIC SKILLS: The use of language can only be done in 4 different ways that the user must master to communicate.

Differences between oral and written communication: oral and ear canal.

The differences between oral and written language have been much studied. On one hand, there is the question of the relationship of the two linguistic codes: whether oral came before written, if they depend on each other, or if these are two
