Investigating learning outcomes in engineering education with data mining

Abstract

Higher education institutions are catching up on their high competition and challenges are in their analysis productivity. The major challenge is to monitor and analyze student progress through learning outcomes in the curriculum. One of the approaches is the outcome-based education (OBE) model to deal with learning outcomes. OBE is an integral part of higher education institutions. The OBE system is a key step for accreditation in engineering education. OBE focuses on a student-centered approach. The OBE is not restricted to welldefined teaching strategies or direct evaluations but also encompasses indirect evaluations to help students achieve the intended outcomes. In this investigation, engineering students' data have been analyzed forming three distinct clusters to group students according to best, average, and worst achievement of learning outcomes in two different computer engineering courses generally taught in the early semesters in higher education institutions. A data mining clustering approach is used to segment students using k-means and k-medoids techniques. Clustering can be regarded as a data modeling technique that provides summary data that interact with multiple disciplines and plays an important role in a wide range of computer applications. The investigation comprises of two parts for analysis: one part of the analysis is the mid-term and final exam scores, the quiz and assignment results, the laboratory results, and the evaluation, together with the learning outcomes achieved, and the other part is the comparative analysis of learning outcomes achieved in both engineering courses clustering with the best, average, and worst attainments, respectively. In this investigation, the results obtained from clustering data points show that the same group of clusters with the best, average, and worst learning outcomes achievements formed using both k-means and k-medoid clustering for one course. On the other hand, a diverse group of clusters with the best, average, and worst learning outcomes achievements formed using both k-means and k-medoids clustering for another course.

An Ensemble Approach to Predict Early-Stage Diabetes Risk Using Machine Learning: An Empirical Study

“…Data preprocessing is a crucial stage in data mining when dealing with incomplete, noisy, or inconsistent data that transforms the data into a usable and optimal form [ 17 , 20 , 32 ]. To continually formulate data in a coherent and correct form, data preparation covers different activities such as data cleaning, data discretization, data integration, data reduction, data transformation, and so on [ 32 ]. For this case study, diabetes data with 17 attributes were collected from the UCI repository which contains different datasets.…”

“…Discrete attributes, often known as nominal attributes, are those that characterize a category. Ordinal characteristics are those qualities that characterize a category and have significance in the order of the categories [ 32 ]. Discretization is the process of turning a real-valued attribute into an ordinal attribute or bin.…”

The Design and Application of College English-Aided Teaching System Based on Web

“…To realize the information sharing of English-assisted instruction systems under the web environment, a model of information detection and resource distributed fusion of English-assisted instruction systems under the web environment is established based on the data mining and feature fusion method of the English-assisted instruction system. e statistical data mining [15] and fuzzy feature detection method [16] are adopted to carry out the decision-making scheduling and adaptive optimization of the information process of English-assisted instruction system.…”

Categorizing Well-Written Course Learning Outcomes Using Machine Learning

“…A set of experiments were conducted to select a combination of classifier to achieve an accuracy of 97%. Mahboob et al (2020) collected data engineering students to form three different clusters to group students according to the worst, average, and best accomplishment of CLOs/PLOs in two distinct engineering courses regularly taught in the first semesters. A data mining technique is used to determine Euclidean distances for measuring the similarities through two clustering techniques: k-means and k-medoids algorithms.…”
