CCJS 101 Introduction to Investigative Forensics is a University of Maryland Global Campus survey of how forensic science is actually used in investigations and courts.
UMGC's description sets the aim of learning to apply the scientific method to forensic evidence and to distinguish between reality and popular misperceptions of forensic science and its practitioners.
Discussion covers the "CSI effect", the scientific method as applied to evidence, ethical practices and legal aspects. Topics include how forensic science is defined and has evolved, its disciplines, ethical codes and case law.
Students often arrive with ideas from television. The course asks you to replace them with an accurate picture: slower, more uncertain and more carefully controlled.

Key Concepts Explained
Locard's Exchange Principle and Chain of Custody
Edmond Locard's principle holds that every contact leaves a trace: a person takes something from a scene and leaves something behind. Evidence only helps if its integrity can be shown, so the chain of custody documents everyone who handled it, when and why.
The Scientific Method Applied to Evidence
Examiners form hypotheses and test them, rather than starting from a suspect and looking for confirmation.
Example: Fibers are found on a victim's coat. Hypothesis: they came from the suspect's car. Test: compare fiber type, color and dye with samples from the car, alongside control samples from other sources. Conclusion: the fibers are consistent with the car's carpet, which is not the same as proving they came from that car, since many cars may share that carpet. Stating this limit honestly is what the course means by reality versus perception.
Admissibility: Frye and Daubert
Courts decide whether scientific evidence can be heard. Under Frye v. United States (1923), a method must be generally accepted in its scientific field. Under Daubert v.
Merrell Dow Pharmaceuticals (1993), federal judges act as gatekeepers, considering factors such as testing, peer review, known error rates and acceptance. States use one standard or the other, or a variation.
The CSI Effect and Reform
The CSI effect refers to the idea that crime dramas make jurors expect quick, conclusive forensic evidence in every case. Television shows results in minutes, certainty without error and one investigator doing every job. Real laboratories have backlogs, specialized roles and results stated with limits.
The 2009 National Academy of Sciences report, Strengthening Forensic Science in the United States: A Path Forward, found that several disciplines lacked strong scientific foundations and called for research, standards and independence. It is a useful source for papers on reliability and reform.
Ethics in Forensic Practice
The course covers ethical codes because forensic results can decide liberty. Core duties include reporting results honestly, including those that help the defense, staying within one's expertise, documenting methods fully and avoiding pressure from investigators.
Cognitive bias is a central concern. When examiners know details of the case, they may unconsciously see what they expect. Safeguards include blind verification by a second examiner and limiting exposure to irrelevant case information.
Typical Assignments and How to Approach Them
| Assignment type | What it tests | How to approach it |
|---|---|---|
| Evidence scenario | Scientific method | Hypothesis, test, result and limits |
| CSI effect paper | Critical thinking | Contrast media portrayal with real practice |
| Discipline profile | Field knowledge | Method, uses, strengths and limitations |
| Ethics or case law discussion | Legal and ethical reasoning | Link the standard to a specific case |
Where Students Get Stuck
- Overstating certainty. Use careful language: "consistent with", not "proves".
- Media examples as evidence. Use television only as a contrast, not a source.
- Mixing up Frye and Daubert. General acceptance versus a judge's reliability assessment.
- Ignoring bias. Discuss confirmation bias and safeguards such as blind verification.
Study Tips for CCJS 101
- Make a table of disciplines with what each analyses and its main limitation.
- Read the National Institute of Justice's plain-language material on forensic disciplines.
- Practice rewriting overconfident statements in careful scientific language.
- Keep the chain of custody in mind for every scenario.

Frequently Asked Questions
Practical forensic science: the scientific method applied to evidence, the CSI effect, forensic disciplines, ethics and case law.
The belief that crime dramas lead jurors and the public to expect fast, conclusive forensic evidence in every case.
Frye requires general acceptance in the scientific field; Daubert makes judges assess reliability using factors such as testing, peer review and error rates.
A documented record of everyone who handled evidence, showing it was not altered or contaminated.
Many forensic comparisons show shared characteristics without proving a single source, so careful wording reflects real limits.
