Fascism originated in Italy after World War I and later spread to other countries of Europe. There are three key characteristics:

Authoritarianism

This is the supremacy of the state, which means the state comes before individual rights. Propaganda was used to gain people's loyalty.

Ultra-Nationalism, Imperialism, and Militarism

This was an aggressive foreign policy of territorial expansions that sought to provide the state with more living space. It had a lot of racism and xenophobia because the nation was defined by race.

Economic Control

Capitalism is allowed, but the main goal is to achieve national self-sufficiency through extreme protectionism. The state establishes corporations of business owners and workers, cooperation is encouraged, and... Continue reading "The Origins and Characteristics of Fascism in Europe" »

Programming Fundamentals

What is a Constant?

Three Programming Constructs

The three fundamental programming constructs are: selection, iteration, and sequence.

Logical Operators

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... Continue reading "Teachers' Role in Classroom Technology and Learning" »

The Impact of Reading vs. Television on the Mind

Some people subscribe to the belief that reading helps enhance language skills and creativity, whereas watching television does very little for these abilities. Personally, I support this opinion for several reasons, which will be detailed in this essay.

How Books Stimulate the Imagination

As we all know, books use text to convey ideas, and quite often there are no images or illustrations to picture the scenes described. Therefore, we must use our own imagination while reading. For example, when reading a fantasy novel containing mythical creatures, one typically visualizes the appearance of those characters in their mind while following the plot. In contrast, movie heroes on a TV screen are usually... Continue reading "Why Reading Beats Television for Language Learning" »

Human Nutrition and Body Systems

The digestive, respiratory, excretory, and circulatory systems all play a role in nutrition.

• Digestive system: Introduces foods into the body, and prepares and transforms it to enable its use by cells.
• Respiratory system: Obtains the oxygen cells need and eliminates carbon dioxide produced during cell metabolism.
• Circulatory system: Transports nutrients and oxygen to cells and releases waste substances.
• Excretory system: Releases waste substances outside the organism.

The Digestive System: Function and Structure

The digestive system breaks nutrients into parts small enough for your body to absorb and use for energy, growth, and cell repair. It is made up of the gastrointestinal (GI) tract and the accessory glands:... Continue reading "Human Digestive System: Organs, Functions, and Processes" »
