Effective Way of Studying and Learning in Medical School

ABSTRACT Medical knowledge is growing. We struggle a lot to retain most of the studied information, but we forget it. Most of us are unaware of how to study effectively and improve memory. Understanding the neurobiology of learning and knowing some of the productive study techniques backed up by the researches can help us to study as well as learn effectively. This article may help medical students to study productively and motivate them to search for effective ways of studying actively.

The meaning of studying is to read and memorize facts to learn about a subject. Likewise the meaning of learning means to gain knowledge or skill by studying, practising, being taught or experiencing something. We are born with a very premature brain-probably the result of an evolutionary compromise. As our brain starts to develop, we start to learn every waking moment.
In medical schools, being able to study effectively is essential to cope with the vast amount of information and skills needed to be acquired as medical knowledge is growing. Despite an increase in depth and complexity of medical knowledge in the past decades, the time for medical education remains constant. Most of us are unaware of how to learn effectively and improve memory. We struggle a lot to retain most of the studied information, but we forget it. Understanding the neurobiology of learning and knowing some of the study techniques backed up by the researches can help us to study as well as learn effectively.

NEUROBIOLOGY OF LEARNING
Neuroscientists have defined the various molecular signalling pathways within and between neurons that play a role in learning. 1 The learning experience is stored as a persistent representation, moving from a transient working memory stage that has a relatively limited capacity and time frame to a more long-lasting and stable form of memory with larger capacity that is stored for future access. 2 Learning leads to functional and structural changes in the interconnected cellular networks between neurons (synapses) at a variety of sites throughout the central nervous system. 3 Recent studies have shown that these changes involve a variety of posttranslational modifications of proteins located in proximity to synaptic contacts that can enhance the strength of subsequent signals produced by a presynaptic nerve impulse (action potential) at the postsynaptic neuron. 4 This type of experimental work provides a direct link between the spaced repetition of the information to be learned and the persistence of the changes in the nervous system that accompany such learning. 1

STUDY TECHNIQUES BASED ON RESEARCHES
According to Dunlosky et al, 5

IMPORTANCE OF PRACTICE TESTING AND DISTRIBUTED PRACTISE (SPACED REPETITION)
We have given numerous exams but most of us do not know the essence of the exams. Taking exams is an active and effective way of learning than studying the same thing repeatedly. It also helps in the retention of the information. Also, in case, we cannot answer a test question the retrieval attempts to enhance our future learning. 7 Likewise, frequent classroom testing stimulates practise and review which gives students more opportunities for feedback on their work and has a positive influence on student study time. 8 But, when the students study on their own, most of them repeatedly read their notes or textbook despite the limited benefits of this strategy. Only a few engage themselves in self-testing or retrieval practise while studying. 9

LEARNING IN MEDICAL SCHOOL
Learning in medical school comprises of two types of knowledge: 1. Factual or theoretical knowledge 2. Procedural or practical knowledge Factual or conceptual knowledge covers "what" information, whereas procedural knowledge covers "how" and "why" information. 10 We can become proficient in gaining factual knowledge by practise testing, spaced repetition or distributed practise and interleaved practise. Likewise, we can become proficient in gaining procedural knowledge by problem-based learning and self-regulated learning.
Problem-based learning is not only about problemsolving, but rather it uses appropriate problems to increase knowledge and understanding by going through the triggers and discussing the cases among colleagues and supervisor in a focused group. 11 There is diversity in the use of self-regulated learning strategies by medical students, which is linked to an individual (goal setting), contextual (time pressure, patient care and supervision) and social (supervisors and peers) factors. 12

WAYS FORWARD
Since early childhood, the majority of us were taught to study but we were barely taught about how to study effectively. Medical knowledge is vast, it is evolving now and then. Most of us find medical school to be very difficult because we are unaware of the ways of studying effectively. A lot of researches are being done in studying and learning techniques. We should update ourselves and actively search for new ways to study productively.
