Empirical learning is based on observation whereby either an experiment is carried out and observations made on the results or something happened without the influence of the observer and the results observed. Empirical normally implies that there is no way the results are made to fit into a theory and if there is a trial to do so then there can be no any success. Generally the theory is supposed to predict the outcome of an experiment, mistakes should be discovered in the experiment and resolved and mistakes should be observed in the theory and resolved. However the theoretical knowledge may not be enough to elucidate the results. Theoretical learning is mainly concerned with hypotheses or theories rather than practical or sensible consideration. It usually deals with theories other than how they are applied practically or on theoretical analysis instead of practical analysis. No experiment is carried out and results observed so as to prove the hypotheses. Formation of leading activity in middle childhood During middle childhood, kids face challenges of developmental changes and events which lead to rise in responsibilities and maturity. The major problem is acquisition of productivity logic and not a sense of inadequacy. They is also an expectation of achieving extra developmental tasks at this stage which makes a child to have a sense of identity and the achieved skills enables the children to have a sense of self esteem in the later age. Work and play are seen as the major activities that help children to develop new motives and abilities which outgrow their current activities and this marks a transition to a new stage of development. The children are supposed to acquire a positive attitude towards work and responsibilities. When children develop a positive attitude towards responsibilities and work, the learning children are able to complete their assignments without being regularly reminded by teachers and parents. They are also able to handle their work to the required standards.

Play is unstructured activity that children involve themselves at their own leisure time, not directly connected to school and may be indoor or outdoor games.( Brunstein 2005) When children are playing they are not directed or monitored by the adults and this gives the children a chance to work as and cooperate as a team. They are able to come up with new ideas, direct themselves and resolve conflicts. Play enables the children to improve on how they relate with each other and with the adults. Play mostly involve physical activities and the time and the time spent in playing enables the children to discover new activities which means that the invented activity has come from the previous activity and therefore a change is important and they are able to cope with changes in teen and adult life. Play and work are important since children learn best by doing Consequences of lack of formation of leading activities During middle childhood, children work hard so as to be responsible, to be good and to do things the right w
