Methods to the madness – Activities for the teaching of research methods in AP Research using environmental science

Author: John P. Danihel

School/Organization:

Northeast High School, Philadelphia PA

Year: 2023

Seminar: Children’s Environmental Health

Grade Level: 9-12

Keywords: air quality, atmospheric science, publicly available environmental data sets, research methods

School Subject(s): AP Research

This unit plan was developed for the Advanced Placement (AP) Research teacher to utilize during the teaching of a research methods unit. It contains background information about the current science and technology of environmental air quality followed by teaching activities that can be deployed in the classroom. The intent is to anchor the teaching of research methods within the single theme of the state of the environment and its effects on children’s health. Air quality was chosen specifically due to the poor air quality typically found in urban areas. Four activities are included that allow students to practice various research methods. These activities make use of student generated data as well as publicly available data sets.

Rationale

Environmental science is a subject that has the potential for students to apply what they learned to their everyday surroundings – their homes, schools and workplaces. If we as teachers instill a knowledge of the environment and how it can be impacted by humans, then students will be better able to protect themselves and their families from possible impacts to their health. For example, many schools in Philadelphia have peeling paint which leaves pile of paint chips that accumulate on the floor. When the paint peels off all the way back to the original wall, there is a high likelihood that inner layers contain lead-based paint. Where do these paint chips go? Is the lead in the chips transported back to students’ homes? If we educate students about the dangers of lead in their environment, then they can take steps to protect their health.

Childhood asthma is a major contributor to school absences (Hsu, 2016).  Asthma can be triggered by poor air quality. We can and should educate our students about how humans impact air quality so actions can be taken to improve it. What is the state of the air quality in their schools and homes? What is the air quality in the U.S.? How has it changed? How can it be improved? The activities in this unit plan begin with a local focus in the school and extend to a nationwide focus. It is the intention that educating students about their immediate environment and giving them the tools to investigate it via a research method can make them more informed members of society.

The AP Capstone program

The AP Capstone program was launched by the College Board in 2014 and consists of two yearlong classes – AP Seminar followed by AP Research. The College Board offers an AP Capstone Certificate to students who pass these two classes with college eligible scores. An AP Capstone Diploma is awarded to students who pass both capstone classes in addition to receiving a college eligible score on four other AP exams. The AP Capstone program was developed in response to the need for high school students to design and conduct authentic, big “R” research rather than the little “r” research of summarizing previous studies. Instead of being a subject-specific class, AP Research is an interdisciplinary class in which students develop research questions, read peer-reviewed academic papers, employ research methods, collect and analyze data. The class culminates with the students writing a 5000-word, peer-reviewed academic paper and defending their theses in a presentation, similar to a master’s thesis or PhD dissertation. The research methods unit gives the students a number of tools with which to conduct their research. The idea is to teach the research methods unit early in the year so that students develop their research questions from a method rather than choosing a method based on a research question. Due to the integral nature of this unit, it has become the focus of this unit plan.

Value and timeliness

Although air quality in the U.S. has improved significantly since the passage of the Clean Air Act of 1970, there are continuing factors that impact air quality. High school students should be educated about threats to environmental quality so that they can protect themselves and their families. For example, Philadelphia was home to a Sunoco oil refinery that exploded in 2019 due to a pipe elbow that had corroded from the transmission of hydrofluoric acid. The explosion released 676,000 pounds of hydrocarbons into the environment with 608,000 pounds combusted into the atmosphere (U.S. Chemical Safety and Hazard Investigation Board, 2022). Nearby residents were alarmed at the clouds of “black smoke” that were released from the refinery. Surprisingly, the plume of airborne contaminants was not detected by the air monitoring system because there were no detection devices placed downwind of the oil refinery (Union of Concerned Scientists, 2023). This led city officials to claim that there was no cause for concern.

Another recent impact to air quality in the Philadelphia area came from wildfires originating in Canada. In June 2023, the air quality index (AQI) in Philadelphia reached “hazardous” levels which were the highest levels ever reported since the installation of the air monitoring network in 1999 (Philadelphia Inquirer). The wildfire smoke created a visible haze over the city making breathing difficult and prompting the city to suspend trash collection and move outdoor activities indoors.

According to researchers at the Philadelphia Regional Center for Children’s Environmental Health, 21% of Philadelphia’s children have asthma (Bryant-Stephens, 2012). This is more than triple the national average of 6.5% reported by the Centers for Disease Control in 2021 (CDC, 2023). Furthermore, rates of hospitalization are more than 4 times higher for Black and Hispanic children compared to their white and Asian counterparts (Health of the City, 2021). This often translates to missed days of school. The CDC reports that despite recent nationwide improvements in asthma outcomes, socioeconomic, demographic and geographic disparities persist (CDC, 2023).

These examples serve to place value on the teaching of environmental issues within the secondary curriculum due to their relevancy to the residents of Philadelphia. In addition, PA state education standard – 10.2.12.E – “Analyze the interrelationship between environmental factors and community health,” moves beyond requiring students to merely describe a process but to use higher order thinking skills like analyzing data and evaluating evidence. Hence, these topics can be incorporated into an AP Research methods unit.

Scientific Background
Atmospheric composition

The Earth’s current atmosphere is a mixture of gasses. If water vapor is excluded then air consists of roughly 78% nitrogen, 20% oxygen, 1% argon and 1% “other” gasses that include carbon dioxide, noble gasses, nitrogen oxides and ozone (see table 1). The amount of water vapor is variable in the atmosphere and is biome dependent with deserts nearing 0% water vapor and tropical regions approaching 4% water vapor (NOAA atmosphere, 2023). Environmental scientists are most interested in this 1% “other” because it includes the human-produced greenhouse gasses of CO2, Methane and other pollutants such as ozone and nitrous oxides.

Table 1 – composition of the atmosphere (from NOAA/atmosphere)

Major air pollutants that impact human health

The Environmental Protection Agency (EPA) has identified 6 common air pollutants that negatively impact human health. These are lead, ground-level ozone, particulate matter, nitrogen dioxide, sulfur dioxide and carbon monoxide. The sources of these pollutants come mainly from emissions from the industrial and transportation sectors. Children are especially susceptible to the health effects of these pollutants because their lungs are still developing and they may breathe in a higher volume of air while playing outside. (America’s children and the environment, 2019). Table 2 summarizes these pollutants and their sources.

Table 2 – Common air pollutants (adapted from America’s children and the environment, 2019)

Pollutant Anthropogenic Source(s) Health effect(s)
lead lead smelters, aviation, marine and farm equipment fuel adversely affects the central nervous system development in young children leading to lower IQ and behavior problems
ground-level ozone produced by a photochemical reaction involving sunlight and tailpipe emissions irritates lung tissue, aggravates respiratory illnesses like asthma and bronchitis, has been linked to causing asthma (Kajekar, R. 2007)
particulate matter occurs as tiny particles of dust from industrial processes and soot from fossil fuel combustion decreased lung function, exasperation of allergic reactions, aggravates asthma
nitrogen dioxide fossil fuel combustion aggravates asthma
sulfur dioxide fossil fuel combustion aggravates asthma
carbon monoxide incomplete fossil fuel combustion inhibits red blood cell’s ability to carry oxygen
The Clean Air Act of 1970

The EPA and the Clean Air Act were both created in 1970 in response to the presence of thick smog in U.S. cities that was injurious to public health. The EPA was given the power to monitor and enforce air quality standards. Since the inception of the Clean Air Act, air quality has improved in the U.S. See figure 1 from the EPA below.

Figure 1 – Declining national air pollutant emissions from “Our nation’s air trends”, 2021

Distribution of pollutants that impact human health

According to the 2023 “State of the Air” report from the American Lung Association, approximately one third of U.S. citizens live in counties that received failing grades for ozone and particulate matter pollution. On the positive side, fewer counties received a failing grade than in previous reports. On the negative side, people of color are almost four times more likely to live in a failing county than white people (State of the air, 2023).

Asthma

Asthma is a chronic respiratory disease in which breathing is difficult due to the inflammation of lung tissue (American Lung Association). There is no cure for asthma but it can be managed so that asthmatics can lead a normal life. Asthma can be triggered by the pollutants mentioned above (see table 2) in addition to cigarette smoke, pet dander, dust mites, mold, physical activity, even perfumes and cleaning solutions (Burbank, 2018). Individuals who grow up in urban areas have a higher chance of developing asthma because of proximity to sources of air pollution.

The CDC reports from an analysis of 2006-2018 health data that despite a decrease in asthma attacks and mortality among U.S. children, the disease disproportionally affects Black and Hispanic children of low income. The report suggests that asthma is exacerbated by lack of access to quality health care (Pate, et al. 2021). Figures 2 and 3 below compare the asthma hospitalization rate among children in Philadelphia and household income. A side-by-side comparison of these maps show that the highest hospitalization rates coincide with the lowest household income.

Research methods background

            This unit plan was developed for the AP Research teacher to implement a research methods unit with an underpinning of environmental science focused on air quality and its impact on humans. In general, research methods are used in studies to collect data. Collecting original data is a core tenant of the AP Research class without which they cannot earn a college eligible score. While any valid research method can be used by the student, a few of the more student-friendly and accessible methods are used in this unit plan.

A research project begins with an approach. The two approaches exemplified here are experimental and non-experimental (or descriptive) approaches. Experimental approaches involve the manipulation of an independent variable to measure the change in a dependent variable. The researcher maintains control over the manipulation and attempts to keep other factors from affecting the independent variable so that valid conclusions can be drawn about the dependent variable. Experimental approaches aim to describe cause and effect. Non-experimental approaches often analyze the relationship between events that have already happened. Here, the researcher has no control over the independent variable.  Because the researcher cannot control the independent variable, a correlation can be drawn between the variables but causation cannot.

Research methods fall into two broad categories – quantitative and qualitative. Quantitative research collects numerical data, or quantities. Qualitative research typically collects non-numerical data like words or images. A research question may also be answered by using a mixed methods approach that utilizes both quantitative and qualitative data. This unit plan focuses mainly on the research methods with minimal attention paid to the analysis of data since that is the topic of a whole separate unit. It is suggested that the AP Research teacher utilize some of the data collected in this unit for future lessons on data analysis and reporting.

Survey research

Survey research is used to measure people’s attitudes, opinions and beliefs, An example is the Gallup poll that is used to ask the opinions of voters’ political views.  Both experimental and non-experimental (descriptive) research make use of surveys to collect data. Survey research includes questionnaires, interviews or a mix of the two. Surveys are the most popular type of research method used by the AP Research student due to their ease of creation, distribution and analysis. Google forms and Survey Monkey are two examples of questionnaire software that allow students to write different question types, send it out to survey participants, and see data visualizations. Questionnaires may contain both closed-ended (quantitative) and open-ended (qualitative) question types. A survey needs to be written so that it can be completed without the researcher being present (Christensen). Finally, surveys require informed consent of the participants and the AP Research teacher may use this opportunity to have the students practice writing informed consent forms.

Christensen, et al summarizes these principles of questionnaire construction in “Research methods, design and analysis:”

Interviews are conducted in one-on-one and/or focus group format. The researcher writes a series of questions for an interview protocol and writes down or makes an audio recording of the responses. The interview may be structured or semi-structured, depending on the level of formality that the researcher wishes to create. During interviews, the researcher has more control of the data collection and can make use of follow up responses to elaborate on some topic (Christensen).

The qualitative data that comes from open-ended questions and interviews allow for a richer description from the research participants than answering an opinion question on a scale of 1-5 as in a questionnaire. Two more research methods – thematic analysis and content analysis – can then be employed to categorize and connect the data. During thematic analysis, the data is first coded for theme type and frequency. After the initial codes are generated, the researcher recodes the data to search for explanations of the themes (Braun and Clarke, 2006). Content analysis takes this process one step further and allows for hypothesis testing or theory generation.

The use of survey research allows students to be introduced to the concept of limitations in research a few of which are mentioned here. If students are distributing their surveys electronically, then they will notice the response rate will not be 100%. This will affect their sample size. If survey questions ask participants to remember an event then those responses will be subject to recall bias which may or may not reflect that event accurately. Social desirability bias seeps into to survey research when the participant responds with an answer that bolsters their status rather than admitting fault. Lastly, researchers need to be aware of researcher bias where the researcher is only asking questions to support some hypothesis rather than going about research in the most objective way possible.

Pretest posttest design

The pretest posttest design can be used to extend survey research from a non-experimental (descriptive) to an experimental design. The process involves measuring the extent of a variable with a pretest, interjecting a treatment of some kind, followed by measuring the effect of the treatment with a post-test (Bell, 2022). If a control group is used, then this is an experimental design. If no control group is used, then this becomes a quasi-experimental design. Limitations to this design include threats to internal validity which are weakness to how the research method is implemented. Threats to internal validity include testing saturation bias and attrition (Matthay and Glymour, 2020). When administering the post-test, participants may gloss over some of their responses the second time and not answer accurately. Attrition bias occurs when participants drop out of a study. These “practice runs” with using research methods prepare the AP Research student to look out for and overcome obstacles when they arise in their own research project.

Correlation research

            Correlation research seeks to identify an association between two dependent variables. Association is not to be confused with causation. Cause and effect relationships can only be determined through experimental designs that utilize random selection and a control group (Sheskin, 2022). Correlation research lacks the use of a control group. With correlation research, two data sets are plotted against one another in regression analysis that yields an equation. This equation is descriptive and is only used to predict the value of one variable from the other rather than claiming causation. Regression analysis allows the researcher to identify a direct or indirect relationship between the two variables. In direct relationship, an increase in one variable leads to an increase in the other. In an indirect relationship, an increase in one variable leads to a decrease in the other. This relationship is represented by the correlation coefficient, r, which ranges from +1 to -1. The closer the r-value is to ±1 signifies the strength of the correlation. Weaker correlations have an r-value closer to zero.

Causal comparative research

            Causal comparative research seeks to find a relationship between an independent and dependent variable after an event has already occurred (Brewer and Kuhn, 2022). It is also called “ex post facto” research meaning “after the fact” because the researcher cannot manipulate the independent variable. It is similar to correlational research in that it can be used to identify relationships where it may be unethical to conduct experiments such as the impacts of air quality on children’s health. Both causal comparative and correlation research lack random assignment which limits their generalizability to a larger population. Causal comparative research, however, makes use of a control group which allows the researcher to test the possible effects of a treatment on an independent variable. While causal comparative designs are not true experimental research, they do allow the researcher to isolate the effects on an independent variable with more certainty.

Teaching Strategies

Teaching strategies vary in this unit but utilize both teacher-centered and student-centered instruction. There are advantages and disadvantages to each. Many teachers use a mix of methods to reach the many different learning styles in the average classroom. Ultimately, it is the teacher’s responsibility to create an environment that is conducive to learning and has latitude as to which strategy works best for them. This section contains the teaching strategies used in this unit with a short rationale for each.

Whole class instruction

Whole class instruction is the traditional mode of instruction where the teacher stands in the front of the room and delivers instruction using a lecture style with probing questions. It is the fastest way to teach the most content and can be described as teacher-centered instruction. It is used here to deliver environmental science content because AP Research is not a content driven class but a process driven one. Some students, however, have difficulty learning through this method because it is viewed as a passive way of learning rather than an active one. The activities presented here begin with a whole class instruction of 10-20 minutes, followed by classwork that the students can engage in “learn by doing.”

Small group collaboration

Small group collaboration is a student-centered teaching method that allows students to work together on a task. Since the peer review process is an integral component of graduate and professional research, peer review groups are created in the AP Research classroom to emulate that process.  AP Research teachers are not allowed to revise or edit student work so the onus is placed on the students to work with their peers. For example, students review each other’s surveys and informed consent forms for clarity before they are put into operational data collection mode. Students may be put into peer review groups for many of the tasks required in AP Research from revising research questions to editing their final manuscripts before submission to the College Board.

Assigned readings

Homework can help introduce new concepts, allow students to practice something that they have learned, or it can be busy work. Since the latter wastes student’s time and creates a disaffection towards homework, readings are assigned thoughtfully and with purpose. Instead of assigning students to read, for example, the entire chapter 4 in the research methods textbook, readings are shortened to smaller page counts. For example, students are given a 3-page reading assignment about pre and posttest designs and then asked to answer a question about exactly when this method can be used. This allows the teacher to assess whether or not the student did the reading assignment and focuses the students’ attention on the important concepts, rather than just reading to read. Students have provided feedback that this “chunking” of reading sections is preferable to reading an entire chapter.

Independent work

The research methods unit is a trial run of how to conduct different types of research. While small group collaboration is necessary for the peer review process, students need to learn how to conduct these research methods on their own so that they can apply what they have learned to their own research question. The following activities require students to do some steps independently, like calculating the correlation coefficient, r. After the independent work is complete, the peer review process can be employed.

Use of the computer as a tool

Many of the secondary data sets that are used for these activities are found on government websites. Students get practice downloading data and putting it into software that allows for analysis. Google docs, sheets, slides and forms are used in these lessons due to their user-friendliness and availability.

Classroom Activities

Activity 1: Descriptive/evaluative research using surveys – an intro to survey writing (2-3 days)

Objectives: Students will be able to write an informed consent form for a survey. Students will be able to write a survey that describes/evaluates opinions about the perceived indoor air quality of their school.

Motivate: Provide an example of an indoor air quality survey (see Appendix 1). Include an example of informed consent (see Appendix 2).

Instruct:

Day 1 – Teach a lesson about the effects of poor indoor air quality on students with asthma. The lesson should include a definition of particulate matter, its sources and occurrences in an indoor environment. Additionally, the lesson should include the effects of indoor air pollution on asthmatics.

Day 2 – Teach a lesson about the principles of questionnaire construction using the sample provided. Students should see examples of scaled responses (Likert scales), closed ended, open ended, checkboxes and ranking scale type questions.  Show students an example of informed consent and parent approval.

Produce: Students produce a survey in Google forms with an informed consent and parental permission. The survey is geared to gather perceptions of indoor air quality in the school and possibly gather quantitative data from asthmatics about frequency of air irritants. Students pilot/field test their surveys using small group collaboration.

Assess: Students peer review each other’s work for strengths and weaknesses of question wording and quality of data obtained per a grading rubric (See appendix 3). Student assessment is combined with teacher assessment.

Extension: Activity could be adapted to perform action research where students would identify a problem through survey research, attempt to fix the problem and then re-evaluate to assess if the problem has been fixed.

Activity 2 Experimental research using a pretest posttest design (2-3 days)

Objective: Students will apply the pretest posttest design to assess which is the most effective method in educating their peers about air quality.

Motivate: Run the experiment on the students. Since this survey is for demonstration purposes, they do not need to acquire parental consent. Give students a pretest about environmental awareness (See appendix 4). Then, have them read a brochure about one of the environmental issues for example, EPAs particulate matter brochure (See appendix 5). Finally, issue the posttest. By this time, most students have figure out that they are part of an experiment that is the lesson.

Instruct:

Day 1 – Run the experiment on students.

Day 2 – Teach a lesson about particulate matter and outdoor air quality. The lesson should include sources and transport of particulates in the outdoor environment. Then, pose a hypothesis for students that ties back to AP Research. Ask  – what is the most effective way of educating the public about an environmental issue like air quality? Students can brainstorm in small groups and can share out their ideas in a class discussion. Answers should include brochures, public service announcements, social media, YouTube videos, etc.

Day 3 – Teach a lesson about experimental research using the pretest posttest control group design. Assign students into groups to write a pretest about the average person’s knowledge of the occurrences and effects of outdoor particulate matter. Each group will then test which form of media is the most effective in raising awareness about outdoor air quality. Students can find videos, social media postings or brochures and test the educational impact on their peers in other classes. There needs to be a control group that does not receive the treatment. The posttest is then administered.

Produce: Students are tasked with writing and administering a pretest and posttest (with informed consent) in Google forms. Students need to research educational media about particulate matter as part of the treatment.

Assess: Students will assess themselves according to a grading rubric (see appendix 3). Student assessment is combined with teacher assessment.

Extension: Students can brainstorm about other uses for this experimental design as it might apply to their AP Research project. This assignment may be altered so that only a post-test design is used.

Activity 3: Correlational research – Pearson’s correlation coefficient with current asthma prevalence vs tons of air pollution per year in the U.S. (2-3 days)

Objective: Students will be able to determine the association between two dependent variables to determine the Pearson correlation coefficient from real world data.

Motivate: Ask students – is there an association between the amount of air pollution in the U.S. and prevalence of childhood asthma?

Instruct:

Day 1 – Teach a lesson about the prevalence of childhood asthma in the U.S. using whole class instruction. The lesson should include the demographics of the children with the highest asthma prevalence. Introduce students to National Health Interview Survey Data from the Centers for Disease control website (see sample in appendix 6). This data set shows population estimates and asthma prevalence back to 2001. Instruct students how to make a Google sheet that lists the population estimate (in thousands) by year.

Day 2 – Teach a lesson about correlational research. Emphasize that correlation does not equal causation. Direct students to the EPAs “Our Nation’s Air” website that shows the millions of tons of air pollutants per year. Students can download a spreadsheet of the emissions totals per year (see appendix 7). Students input the data for PM 2.5 by year into their spreadsheet of asthma prevalence by year. Instruct students to make a scatterplot of the data and use the available functions in Google sheets to write the equation of the function and calculate the correlation coefficient, r.

Produce: Students will correlate millions of tons of PM 2.5 emissions per year with childhood asthma prevalence to assess strength or weakness of the association.

Assess: Graphs need to have titles, labeled axes, correct units, and should communicate the correlation between the variables

Extension: This activity could be subdivided into ethnicity to see if asthma prevalence is increasing or decreasing among whites, blacks, Hispanics, etc.

Activity 4: Causal Comparative Design of asthma hospitalizations among children and archive data of Philadelphia air quality from the EPAs air monitoring network.

Objective: Students will tabulate archive PM 2.5 data over a 5-10 year time span for selected air monitoring stations in Philadelphia and compare that data with zip codes that have a high number of hospitalizations versus a low number of hospitalizations.

Motivate: Introduce students to the city of Philadelphia’s “Health of the City” report.

Instruct:

Day 1 – Teach a lesson about causal comparative design using whole class instruction. Differentiate causal comparative with correlational design by emphasizing that a control group is needed for causal. Reference the “Health of the City” report and show students the “Asthma hospitalization rate among children by zip code” graphic (Figure 2).  Then, direct students to the “Air now – interactive map of air quality” so that they can see the location of air monitors in Philadelphia (see appendix 8). Pose a hypothesis – is there a causal comparative relationship among poor air quality and childhood asthma hospitalizations? Is there poor air quality in areas of the city with fewer asthma hospitalizations?

Day 2 – Direct students to the EPAs “outdoor air quality data” website. Students should use the “Asthma hospitalization rate” graphic to determine the zip codes with the highest rates. Then, students can locate the air monitor within that zip code and run a multi-year tile plot to create a 5-10 year average PM 2.5 pollutant level (appendix 9). The independent variable is the amount of PM 2.5 pollution and the dependent variable is the hospitalization by zip code. The control group can be a zip code with fewer hospitalizations. Students can choose an air monitor within one of these zip codes and compare the level of PM 2.5 pollution between monitoring stations.

Produce: Students will generate a table of data that averages PM 2.5 over a desired time span for selected monitoring stations. They will need to compare the level of pollution with hospitalizations to assess if a causal comparative relationship exists.

Assess: Students should provide written description of the procedure that they used in the causal comparative method with tables and figures. This is practice for them before they write the research methods of their paper.

Extension: Students can investigate other sources of publicly available data that they can use in their research projects.
