Abstract Novel coronavirus widespread has impacted on lots of areas in an around the world. Among that Educational Sector comes under the picture where students are the elements which has been effected with higher rate .In this study the students problems has considered for research to find out the desire solution to reduce the depression of the students during covid-19.model has developed in this study to predict and analysis of students bottom line problems during COVID-19 finding the solution using students dataset of their various difficulties duringCOVID-19 of Bangalore. The random forest(RF), decision tree(DT), support vector machine(SVM), logistic regression(LR), K-nearest neighbor(KNN), and naive Bayes(NB) data set id tested by different Data Mining(DM) algorithms using weka data science tool to develop the models. The result model predicted the Major Problem faced by students during COVID-19 pandemic. Students data set has been examined with decision tree is more accurate to identify the students problem. The accuracy of this algorithm has been noted 95.85% which can be considered the best developed model among the different models which is being developed by other algorithms including K-nearest neighbor, support vector machine, logistic regression, random forest, and. naive Bayes

  1. INTRODUCTION

    COVID-19 has impacted on globally, due to this situation colleges and universities have closed in many countries this is short-term but many people are affected by this in all over the world: there is a big challenge for students and teachers in the education sector teaching and learning process. These nationwide closures are impacting over 60% of the worlds student population. In this study different data models are developed with students data of major problem faced by the students during COVID-19 survey. These models can be used in the Educational organizations and government to identify the solution and solidity of the problem. The models are evolved with the data which has been collected from survey questioner method and dataset instances of the students problem were considered. Different data mining algorithms were examined on weka tool to design the models.

  2. LITERATURE SURVEY

    2013, the author Sharma and Mamta, are implemented the DT model which compared with Naïve Bayes algorithm which has Comparison of different models to predict the result of students in the form of efficiency [12]. In 2009, Siraj,

    Fadzilah, and Mansour Ali Abdoulha are used different algorithm with weka tool to better understanding, analysis and clustering of Graduates data [13]. 2009, Hoo Yann Seong are used Neural Network and DT with that they have predicted model by comparing with classifying and clustering of students performance in their organization[14]. 2008, Espejo, and César Hervás used different algorithm to develop the data mining model and concluded with his research that DT is the best model for educational sectors in terms decision making[15]. 2007, Janecek, and Peter Haddawy DT and NB have considered consistently 3-12% more accurate when comparing with other models in predicting the performance of academic [16]

  3. METHODOLOGY

    The dataset was obtained from questioner survey which has been collected from different college students in Bangalore. Which contain 734 instances with 7 attributes which are: are you Anxious about your Education during COVID-19 then what is the Scale of your Anxiety? What is your lack of concentration Scale on online sessions? (Under which Scale you find lack of concentration issue) Are you under Uncertainty or Dilemma about University and UGC Decisions? What is the Scale on Lack of Clarity and Communication about topic delivered on online sessions? Impact Scale on Lack of Physical Presence in understanding Class Are you facing Network issue during online class? Scale of Difficult to understand the online class without facial expression and body language Test mode: evaluate on training data these dataset are collected and analyzed with proper parameters for data analysis we have different types open source software and algorithms are available like KNIME, Sisense.,Rapid Miner, , Oracle Data Mining, Orange, SSDT (SQL Server Data Tools), Weka, Apache Mahout etc. these Software are useful to analyze the data more efficiently and predict the error and models using different algorithms. Among these tools weka has been selected to analysis and prediction of model based on dataset. When considering the function of data mining includes tracking patterns. One of the most basic techniques in data mining is learning to recognize patterns in data sets which contains the different faces like as shown in fig1

    Fig 1 Method of Data Processing

    In the fig a shows the process in data analysis and prediction methodology in the research using data mining to predict the model which is helpful to identify the major problems faced by the students during the covid-19 pandemic situation

  4. VISUVALIZATION OF OUTPUT

    Fig 2a.Lack of Concentration

    The fig 2a contains the graphical presentation of online sessions where the students comes under lack of concentration. Which contains the session time duration with three scales first scale is 0 to 30 minute, second scale 30-60 minute and last scale is more than 60 minutes among these scale 51.4% students are facing the lack of concentration. And considered as students problem in online session during COVID-19.

    Fig2b Anxiety level

    The Fig 2b represents the graph of anxiety level among the students about education in the pandemic situation.it has been noted 60.7% students are higher in scale and which is considered as the problem faces by students.

    Fig2c. Uncertainty

    From fig2c shows the maximum 80.3% of students are under uncertainty about university decision.

    Fig2d Lack of clarity and Communication

    The fig2d indicates the issues of lack of clarity and communication about topic delivery during online session 30.6% students are considered as height scale of issue but when considered with other scale it has not been considered as the major problem of students.

    Fig2e Lack of physical presence and understanding

    In the Fig2e indicates the impact scale on lack of physical presence in understanding the session and which is recorded as 52.5% students are in higher risk.

    Fig 2f Network issues

    In this graph Fig2b has been observed that 92.2% of students are facing the network issues during the online sessions and this scale is considered as another problem faced by the students during COVID-19

    Fig 2g Facial Expression and Body language

    This Fig2c is the Scale presentation difficulties to understand online session without facial expression and body language. 53.6% students are considered as major problem and 37.7 % of students as massive.by the analysis it is also be considered problem among one of them.

    Fig2h: Data mining Method applied on data set

    Data set has been applied on the data mining methodology to predict the model. Data set is applied the preprocess method to generate Preprocessed Data. This is further applied for different types ofvalidation by the model design. After this face data set is passed to model building face by applying different data mining algorithm for examining the data set which deployment for evaluation process by applying the logic which contains if anxiety level of the student is yes, uncertainty problem facing is yes, Clarity and lack of physical presence is yes, network issue and facial expression issue is yes then the prediction level is considered as major issue or problem. The organizations of educational institutes can take decision and can find out the solution for the problems.

  5. FINDINGS AND DISCUSSIONS

    The different Data Mining algorithm such as K-nearest neighbor logistic regression, random forest, decision tree, naive Bayes and support vector machine were examined on the data using WEKA tool. The model evolved with decision tree algorithm was examined with height accuracy of 94.85% and this model is considered as best model among others data models.
