In research, experimental designs are essential for establishing cause-and-effect relationships. However, conducting true experiments is not always feasible due to ethical, logistical, or financial constraints. This is where quasi-experimental design plays a crucial role. Quasi-experimental designs allow researchers to study causal relationships without randomly assigning participants to groups. These designs are commonly used in social sciences, healthcare, education, and public policy when randomization is impractical or unethical. This guide explores: What is a Quasi-Experimental Design? 🔹 Definition A quasi-experimental design is a research approach that examines cause-and-effect relationships but lacks random assignment of participants. Unlike true experiments, where subjects are…

Bronfenbrenner’s ecological model, also known as the ecological systems theory, explains how different environmental systems influence human development. Developed by psychologist Urie Bronfenbrenner, this model emphasizes the interconnected relationships between individuals and their surrounding environments. The model consists of five key levels: the microsystem, mesosystem, exosystem, macrosystem, and chronosystem. Each level plays a role in shaping an individual’s behavior, growth, and development. This article explores the components of the ecological model, real-world examples, and its significance in psychology and education. The Five Levels of Bronfenbrenner’s Ecological Model Detailed Explanation of the Five Levels Curious about Bronfenbrenner’s Ecological Model? Eureka Technical…
Adsorption and absorption are two distinct processes that involve the interaction of substances, particularly in chemistry, physics, and industrial applications. While adsorption refers to the adhesion of molecules onto a surface, absorption involves the uptake of one substance into the bulk of another. This article explores the fundamental differences between adsorption vs. absorption, their mechanisms, examples, and real-world applications. What is Adsorption? Adsorption is the process in which molecules, atoms, or ions adhere to the surface of a solid or liquid without penetrating its internal structure. This phenomenon is widely used in industrial filtration, catalysis, and material science. How Adsorption…
