  <abstract>Today, learner grouping has an important role in the sagacity of E-learning systems. In recent researches in this
field, researchers have tried to improve basic grouping methods by combining them with optimization approaches. This
complicates learner grouping methods and one dimensionality looking toward clustering, causes the quality of the produced
groups decreases. This paper proposes a new method based on feedback from basic clustering method such as fuzzy c-means
and k-means which it is called Hybrid Clustering Method (HCM). To judge of the best cluster, in HCM, based on clusterâ€™s
center proximity, a correspondence is made between similar clusters and then the best cluster is selected among similar
clusters based on an index relating to the clusterâ€™s density concept. In the next stage, repetitive and eliminated elements are
modified. This method looks at clustering problem as perspective of several different methods while maintaining the simplicity
of basic cluster algorithms. The proposed method is evaluated and compared with other methods by using Purity and
Gathering (P&amp;G) index. The experimental results show that the proposed method has the best results when compared to the
other methods such as fuzzy c-means, k-means and Evolutionary Fuzzy C-means (EFC) in perceptual dimension of learners
grouping.</abstract>
