Intelligence plus character — that is the goal of true education

Martin Luther King Jr.

Case studies are a useful tool in teaching various subjects. Case study method is a group, student-centered and results-oriented exercise that includes each learner’s input, provides opportunities for meaningful conversations and holds them accountable for their learning.

In general, researchers put forward the following advantages of case-study method, it promotes:

-        in-depth study of a phenomenon within its real-life context;

-        critical thinking and analytical abilities;

-        communication skills;

-        abilities to defend one’s point of view;

-        tolerance to different views;

-        research skills [2, 4, 5].

In the meantime, case study method is criticized for its disadvantages:

-        inappropriate for elementary level;

-        difficulties of time management;

-        difficulties of the validation of the solutions [3].

Despite these drawbacks, this method is rather productive and its advantages far outweigh its disadvantages. The use of case study includes the following stages:

-        familiarization with the task;

-        analysis of the theoretical material;

-        planning;

-        conducting a research;

-        discussion;

-        summarizing and presentation of the research results;

-        analyses of the findings based on the assessment criteria [6].

Choosing a task for a case study, a teacher should take into account the following crucial requirements:

-        presence of a practical problem with multiple decisions;

-        terminology and style of the problem description correspond to those used in reference and professional literature;

-        theoretical data must be given to learners in a generalized form;

-        self-dependent and creative activity of learners [1].

Using this method, a teacher should plan ahead and think about possible needs and challenges of his learners. He should act as a facilitator who is willing to listen, ask open-ended questions and encourage a further discussion.

There exists a diversity of worthy case study topics for discussion during which learners exchange their experience and thoughts. For example, teaching chemistry, a teacher can use the following cases:

-        Why automobile companies produce cars working on hydrogen fuel? What are the properties of hydrogen fuel?

-        What is oceans’ contribution to the fight with global warming?

-        What are the pros and cons of soy-based foods?

-        What is the contribution of organic chemistry to global food production?

-        What are antibiotic-resistant bacteria? And why are they a challenge of modern medicine?

-        What is the influence of chlorine on a human body while swimming in swimming pools? How can the influence of chlorine be minimized?

-        What are the main sources of water pollution? What are the methods of water purification? Why is there no clean water in nature?

-        What are the possible threats of methanol production to the environment? Can you offer methods to prevent them?

To sum up, it may be said that case-study method is a creative complement to traditional teaching approaches. It establishes opportunities to put theory into practice, builds critical thinking and problem-solving skills, develops learner’s communication skills, creative potential, promotes collaboration and tolerance.
