Summary of Finding and Managing Scientific Sources
Importance of Skills: Finding scientific sources and managing them are essential skills acquired during university studies, enabling the navigation of vast digital academic landscapes.
Support Provided: Students at Indiana University (IU) are supported by the Library and Information Services (LIS) team through workshops and individual consultations.
Evaluation of Sources:
Sources must be carefully evaluated to determine their appropriateness for citation in academic work.
Systematic management of sources, utilizing suitable software (e.g., Zotero, Mendeley, or Citavi), aids in creating references and bibliographies in correct formats (APA, MLA, etc.).
Effective Reading Techniques: Includes strategies like SQ3R (Survey, Question, Read, Recite, Review) to quickly extract important information.
Citation Guidelines: Citing scientific sources must adhere to IU’s General Citation Guidelines to avoid plagiarism, which is the act of presenting someone else's work as your own.
Literature Discussion: Discussing literature on a topic helps form the foundation for independent arguments by highlighting gaps in current research.
Research Designs: Study Goals
Completion Outcomes: Upon completion, students will be able to:
Discuss differences between fundamental research designs such as cross-sectional, longitudinal, and experimental studies.
Identify key properties of basic scientific formats like monographs vs. journal articles.
Discuss advantages (generalizability) and disadvantages (lack of depth) of quantitative research, and vice versa for qualitative designs.
Name specific methods for data collection (e.g., Likert scales, semi-structured interviews).
Research Designs: Introduction
Role of Research Design: It serves as a blueprint or logical structure of the inquiry, ensuring the evidence obtained enables the researcher to answer the initial questions as unambiguously as possible.
Key Considerations:
Identify relevant academic formats in IT, such as technical reports or conference papers.
Determine approach: Qualitative (exploratory) vs. Quantitative (confirmatory).
Quantitative Research: Focuses on numerical measurements to either:
Deductively test established theories (Theory -> Hypothesis -> Observation -> Confirmation).
Inductively test falsifiability (e.g., recording sensor data from nodes to find patterns).
Qualitative Research: Aims for a deep, holistic understanding of social phenomena. In IT, this includes UX research and Human-Computer Interaction (HCI).
Research Method Selection factors:
Research Goal: Whether to Explain (causal), Understand (meaning), Predict (forecasting), or Criticize (emancipatory).
Pragmatic constraints: Time limits (- months for a thesis) and budget constraints for data acquisition.
Key Formats of Written Work
4.1 Types of Research Formats
Empirical Research:
Collects original primary data to answer a specific research question.
Systematic cycle: Problem definition -> Research design -> Data collection -> Data analysis -> Interpretation.
Literature and Review Work:
A secondary research format providing a meta-level summary.
Systematic Reviews: Follow a strict protocol to find all relevant studies on a topic.
Design Science Research (DSR):
Predominant in Information Systems; focuses on solving problems via artifacts (e.g., algorithms, interfaces).
The 7 Principles of DSR:
Artifact Design: Must be a construct, model, method, or instantiation.
Problem Relevance: Must solve an identified business or technical problem.
Design Evaluation: Requires rigorous utility, quality, and efficacy tests.
Research Contributions: Must provide clear contributions to the knowledge base.
Research Rigor: Requires rigorous methods in both construction and evaluation.
Design Optimization: Iterative search process to reach a solution.
Communication: Results must be presented to technology-oriented and management-oriented audiences.
Correlations
Definition: A statistical measure (expressed by a coefficient between and ) that describes the size and direction of a relationship between two variables.
Caution: Correlation ( and move together) does not imply causation ( causes ).
4.2 Methods: Quantitative or Qualitative?
Qualitative Methods
Smaller, non-representative samples (n < 20) prioritized for depth.
Techniques include Grounded Theory or Ethnomethodology.
Quantitative Methods
Large samples (n > 100) prioritized for statistical power.
Big Data: Involves the Vs: Volume, Velocity, and Variety, requiring specialized processing beyond standard databases.
Method Triangulation
Purpose: To overcome the intrinsic biases and problems of a single method.
Types:
Data Triangulation: Using different data sources (e.g., at different times or from different people).
Investigator Triangulation: Using multiple observers or interviewers to reduce subjective bias.
Theory Triangulation: Using multiple theoretical schemes to interpret the results.
Methodological Triangulation: Using multiple methods, such as a survey followed by an interview.
Data Collection Methods
Qualitative Methods
Data Saturation: The point in data collection when no new information or themes are observed in the data.
Quality Criteria:
Credibility: Internal consistency.
Transferability: Contextual applicability.
Dependability: Traceability of the process.
Quantitative Methods
Experiments: Manipulate an independent variable () to see the effect on a dependent variable () while controlling for extraneous variables.
Quality Criteria:
Objectivity: Result is independent of the researcher ().
Reliability: Consistency of the measurement instrument ().
Validity: The instrument measures what it is intended to measure ().
Data Evaluation Methods
Qualitative Methods
Coding: Labeling and organizing data to identify themes. Software like MAXQDA or NVivo automates the organization of codes.
Quantitative Methods
Data Cleansing: Identifying and correcting (or removing) corrupt or inaccurate records (e.g., outliers or missing values).
Analysis levels:
Univariate: Analysis of variable (e.g., mean, median).
Bivariate: Analysis of the relationship between variables (e.g., Scatter plots).
Multivariate: Analysis of or more variables simultaneously (e.g., Multiple Regression).
