The course is designed to introduce students to the principles and practices of data science, emphasizing both theoretical underpinnings and practical applications. It serves as a prerequisite for advanced electives in data analytics, machine learning, and big data systems, and is a core component of the undergraduate curriculum for majors in computer science, information systems, and applied statistics.
The course is identified by the numeric code 103, reflecting its position as an introductory level offering within the departmental sequence. It typically occupies one semester, with a weekly lecture component supplemented by laboratory sessions and a capstone project. The curriculum is developed in collaboration with faculty from the computer science, statistics, and business analytics departments, ensuring interdisciplinary coverage.
History and Background
Origin of the Course Code
The code DSE103 was assigned during the restructuring of the departmental course catalog in 2010. Prior to this reorganization, data-related courses were scattered across several departments and lacked a unified structure. The introduction of a dedicated data science sequence aimed to consolidate foundational material, streamline credit requirements, and align the curriculum with emerging industry standards.
The decision to number the introductory course 103, following a standard numeric progression (e.g., 101, 102, 103), signified its role as an entry point for students who had completed general education requirements but had not yet engaged in specialized study. The numbering also facilitated cross-registration with partner departments, allowing students from diverse majors to enroll without conflict.
Evolution of Curriculum
Since its inaugural offering in the fall of 2011, the syllabus of DSE103 has undergone several revisions. The first iteration emphasized classical statistical techniques and introductory programming in R. As the field of data science expanded, the curriculum incorporated modern programming languages such as Python, data manipulation libraries (pandas, NumPy), and interactive visualization tools (Matplotlib, Seaborn).
In 2015, a dedicated laboratory module was added to provide hands-on experience with real datasets, reinforcing concepts from lectures. The 2018 revision introduced coverage of cloud-based data services, including Amazon Web Services (S3, Redshift) and Google Cloud Platform (BigQuery). More recently, the curriculum has incorporated modules on ethical considerations in data science, reflecting growing awareness of privacy, bias, and societal impact.
Feedback from industry partners and alumni has continually shaped the course. Regular curriculum reviews ensure that DSE103 remains responsive to technological advancements and workforce needs while maintaining rigorous academic standards.

Each theme is covered through a combination of lectures, case studies, and laboratory exercises. The course begins with an exploration of data sources, including structured databases, semi-structured files, and unstructured streams. Subsequent modules delve into probability theory, descriptive statistics, and inferential techniques, establishing a mathematical foundation for data analysis.
The machine learning segment introduces supervised and unsupervised algorithms, focusing on algorithmic intuition, implementation, and evaluation metrics. The big data module covers distributed computing frameworks such as Hadoop and Spark, emphasizing data partitioning, parallel processing, and scalability considerations.
Finally, the course addresses ethical challenges in data science, covering topics such as data privacy regulations, algorithmic bias, and the responsibility of data scientists in society. This module encourages critical reflection on the broader impact of data-driven decision-making.
Laboratory and Project Work
Laboratory sessions are integral to DSE103, providing experiential learning opportunities. Each lab focuses on a specific dataset and problem statement, requiring students to apply methods learned in lecture. Labs progress from simple data cleaning exercises to complex multi-step analyses involving predictive modeling and data visualization.
The semester culminates in a capstone project, wherein students select a real-world problem, acquire an appropriate dataset, and develop a comprehensive analysis pipeline. Projects are evaluated based on clarity of objectives, methodological soundness, interpretability of results, and presentation quality. This project component is designed to emulate industry workflows and foster collaboration among peers.
Teaching Methodology
Lecture Format
Lectures are delivered in a hybrid format, combining traditional didactic teaching with interactive elements. The instructor introduces concepts using visual aids, example datasets, and step-by-step demonstrations of code. Students are encouraged to ask questions and engage in brief problem-solving exercises during the session, ensuring active participation.
Lecture content is supplemented with assigned readings from selected textbooks and scholarly articles. These readings provide depth and encourage students to explore topics beyond the scope of classroom discussion. The instructor also utilizes supplementary online materials, such as recorded tutorials, to reinforce learning.
Assessment and Evaluation
The assessment framework is designed to promote continuous learning and mastery of key concepts. The evaluation components include:
- Weekly assignments: Short exercises focused on specific techniques, requiring submission through an online portal.
- Laboratory reports: Detailed documentation of lab procedures, results, and interpretations.
- Midterm examination: A written test covering theoretical knowledge and practical problem-solving.
- Final project: An end-to-end data analysis pipeline presented in written and oral formats.
Grading is transparent, with rubrics provided for each assessment. Feedback is delivered promptly, enabling students to adjust their approach and strengthen their skill set before subsequent assignments.
