IDS 100 is the course where most SNHU students first encounter the "four lenses" framework, and it follows them for the rest of their degree. The students who do well in IDS 100 are not the ones who write the most — they are the ones who understand that the assignment is testing whether they can think across disciplines, not whether they can summarize them.
If you are taking Perspectives in the Liberal Arts at Southern New Hampshire University, you have likely already realized this course is unlike the others on your schedule. The reflection papers, the lenses, the milestone projects — IDS 100 is structured to teach a specific way of thinking that the rest of your SNHU degree assumes you have absorbed. This guide unpacks exactly what each milestone asks for, what the four lenses framework actually means, and how to score well on the reflection paper that ties it all together.
What IDS 100 Actually Teaches
IDS 100: Perspectives in the Liberal Arts is the foundational interdisciplinary course in SNHU's general education curriculum. The course teaches you to analyze contemporary issues through four academic lenses: history, humanities, social sciences, and natural sciences. Each lens represents a different way of asking questions and producing knowledge. The point of the course is not to master each discipline — it is to learn that no single discipline produces a complete understanding of any complex issue.
The four lenses framework reappears across your SNHU degree, including IDS 105 (Critical Thinking and Problem Solving), IDS 400 (Diversity), and the IDS capstone. Getting comfortable with it in IDS 100 saves you significant work later.
The Four Lenses, Plainly Explained
The History Lens
The history lens asks: how did this issue come to be? What events, decisions, and shifts over time produced the situation we see today? Historical analysis traces causation across decades or centuries, identifies turning points, and explains how the past shapes present conditions. A history-lens analysis of healthcare access in the US might trace the development of employer-based insurance from World War II wage controls through the Affordable Care Act, identifying how each step constrained the options available today.
The Humanities Lens
The humanities lens asks: how do people make meaning of this issue? What does literature, art, philosophy, religion, or media tell us about how humans understand and express this experience? Humanities analysis examines values, beliefs, narratives, and symbolic meaning. A humanities-lens analysis of healthcare access might examine how illness and care are portrayed in literature, what religious traditions teach about the ethics of care, and how media narratives shape public understanding of healthcare disparities.
The Social Sciences Lens
The social sciences lens asks: how do groups of people behave around this issue, and what patterns can we measure? Social science analysis uses data, surveys, statistics, and behavioral observation to identify trends, correlations, and group dynamics. A social-sciences-lens analysis of healthcare access might examine insurance coverage rates by income, race, geography, and occupation, identifying which populations face the largest barriers and what policy interventions have measurably reduced disparities.
The Natural Sciences Lens
The natural sciences lens asks: what does empirical investigation of the physical world tell us about this issue? Natural science analysis uses experimental methods, biological and physical mechanisms, and replicable evidence. A natural-sciences-lens analysis of healthcare access might examine how delayed care affects disease progression at the cellular and organ-system level, what biological mechanisms underlie health disparities, and what biomedical research demonstrates about treatment effectiveness.
The "Different Questions" Rule: The four lenses are not four different opinions about the same question. They are four fundamentally different types of questions. A history lens asks "how did this happen?" A humanities lens asks "what does this mean?" A social sciences lens asks "what patterns exist?" A natural sciences lens asks "what does the evidence show?" Confusing the question types is the most common reason IDS 100 reflection papers score poorly.
The IDS 100 Milestones
IDS 100 is structured around three milestones that build into the final reflection paper. Each milestone targets a specific skill that the reflection paper requires you to integrate.
Milestone One: Issue Selection
You choose a contemporary issue from a list provided by your instructor or propose one with approval. Strong choices have visible dimensions in all four lenses — issues like climate change, mental health stigma, food insecurity, criminal justice reform, or healthcare access work well. Issues that are narrow or primarily one-dimensional (a single technical question, a purely personal decision) struggle in this course.
Milestone Two: Source Analysis
You identify scholarly and credible sources that approach your issue from each of the four lenses. The milestone is graded on whether you correctly classify each source's disciplinary lens and explain why. This is where many students slip — they classify a source by topic (anything about history goes in "history lens") rather than by the type of question the source asks. A biographical study of a historical figure is humanities, not history, if it focuses on meaning-making rather than causation.
Milestone Three: Reflection on Lens Application
You write a structured reflection on what each lens revealed about your issue and how the lenses together produced a fuller understanding than any single lens could. This milestone is essentially a draft of your final reflection paper.
The Final Reflection Paper Structure
The final reflection paper is typically 2-3 pages, double-spaced, in APA 7 format. The expected structure follows the rubric:
Introduction: Brief identification of your issue and why it matters. One paragraph. Avoid lengthy framing — the rubric rewards content, not preamble.
History Lens Analysis: One paragraph explaining what the history lens revealed about your issue. Include at least one specific source. Focus on causation and change over time.
Humanities Lens Analysis: One paragraph explaining what the humanities lens revealed about meaning, values, and human expression around your issue. Include at least one specific source.
Social Sciences Lens Analysis: One paragraph explaining what the social sciences lens revealed about patterns, group behavior, and measurable trends. Include at least one specific source with concrete data.
Natural Sciences Lens Analysis: One paragraph explaining what the natural sciences lens revealed about physical mechanisms, biological factors, or empirical evidence. Include at least one specific source.
Integration and Reflection: One to two paragraphs reflecting on what the four lenses together produced. This is the highest-weighted section in most IDS 100 rubrics. Explain how the lenses informed each other, where they conflicted or converged, and what understanding you arrived at that no single lens could have produced.
Conclusion: Brief restatement of the key insight from interdisciplinary analysis. Avoid summarizing each lens again — that wastes word count.
References: APA 7 reference list with all sources cited. At minimum, one source per lens.

The Mistakes That Cost Points in IDS 100
Mistake 1: Classifying sources by topic, not by lens. A book about the history of vaccines is not automatically a history-lens source. If the book is primarily about the cultural and ethical meaning of vaccine resistance, it is humanities. If it presents statistical analyses of vaccination rates by demographic, it is social sciences. If it explains the immunological mechanisms, it is natural sciences. The lens is determined by the question the source is asking, not the subject matter.
Mistake 2: Writing four separate mini-papers. The integration section is the most heavily weighted part of the rubric, but many students treat it as an afterthought. Strong reflection papers spend nearly as much space on integration as on the lens analyses combined.
Mistake 3: Generic sources. Wikipedia articles, general news websites, and basic encyclopedia entries do not satisfy the scholarly source requirement. Use the SNHU Shapiro Library to find peer-reviewed articles, books from academic publishers, and credible primary sources.
Mistake 4: Weak integration. "All four lenses are important for understanding this issue" is not integration — it is a statement of fact. Integration means specifically explaining how the lenses informed each other. For example: "The history lens revealed that current healthcare access patterns developed from twentieth-century policy choices; the social sciences lens revealed that those patterns persist with measurable racial disparities; together, they suggested that the disparities are not natural but constructed and therefore changeable."
Mistake 5: Missing APA 7 citations. Every claim that comes from a source needs an in-text citation. References at the end without in-text citations throughout the body is one of the most common rubric deductions.
A Strong Integration Example
Here is what a strong integration paragraph looks like for an IDS 100 reflection paper on mental health stigma in the United States:
Examining mental health stigma through all four lenses produced an understanding that no single lens could have provided. The history lens showed how mid-twentieth century deinstitutionalization without adequate community resources created a public association between mental illness and homelessness or violence (Goffman, 1961). The humanities lens revealed how decades of literature and film reinforced these associations through stigmatizing portrayals, embedding the stereotypes in popular culture (Wahl, 2003). The social sciences lens then documented the measurable consequences: lower rates of help-seeking, employment discrimination, and worse health outcomes among people with diagnosed mental illness (Corrigan et al., 2014). Finally, the natural sciences lens demonstrated that mental illness involves identifiable neurobiological mechanisms — undermining the cultural narrative that treats psychiatric conditions as moral failings rather than medical conditions (Insel, 2010). Taken together, the lenses showed that stigma is neither natural nor inevitable but a product of historical decisions, cultural narratives, social patterns, and a lag in public understanding of the biological evidence. Reducing stigma therefore requires intervention at all four levels — policy reform, narrative change, anti-discrimination measures, and public health education — rather than any single approach.
Notice how each sentence does specific integration work — connecting one lens to the next, naming specific findings, and building toward a synthesis that no single lens could produce. That is what graders are looking for.
"I thought IDS 100 was busywork until I hit IDS 105 and realized everything I had learned about the lenses came back. Then it kept coming back in IDS 400 and again in my capstone. The students in my cohort who took IDS 100 seriously breezed through every interdisciplinary paper after that. The ones who phoned it in were stuck redoing the same skills three years later."

How IDS 100 Connects to Later Courses
The four lenses framework is reused throughout SNHU's general education and capstone sequence. IDS 105 builds critical thinking skills on top of the lens framework. IDS 400 applies the lenses specifically to diversity and inclusion topics. The IDS capstone synthesizes the lenses across a major final project. The students who internalize the framework in IDS 100 spend significantly less time relearning it in later courses.

Final Thoughts
IDS 100 is one of the few courses in your SNHU degree where the skills you build matter more than the grade you receive. The four lenses framework will appear again — in critical thinking, in diversity studies, in your capstone, and in your professional life whenever you encounter a complex problem that resists single-discipline analysis. Treating IDS 100 as a course to coast through is a false economy. The students who engage with the framework save themselves significant rework in every interdisciplinary course that follows.
If your reflection paper grades are not where you want them, the fix is usually one of two things: better source classification (asking what question each source is actually asking, not what topic it covers) or stronger integration (explaining how the lenses inform each other rather than just summarizing what each lens said).
