Teaching Philosophy: Three Core Tenets
Teaching Philosophy:
Building Relationships With Students
I aim to catalyze students' growth and self-discovery by endeavoring to meet students where they are in their educational journey, acknowledging the diversity of their backgrounds and experiences. I operate from the belief that student-centered learning, inclusivity, and mutual understanding are paramount in building relationships with my students. I actively seek feedback from throughout the academic term to ensure that my teaching methods are responsive to students’ needs and learning styles. I prioritize fostering an environment where students feel empowered to share their thoughts and insights, enabling me to continually enhance my instructional practices to better serve them. Demonstrating a commitment to lifelong learning, I model humility in acknowledging what I do not know and engage in active problem-solving alongside my students. I emphasize the value of diverse perspectives, encouraging respectful challenges to students' own beliefs and those of their peers.
Teaching Philosophy:
Discussion & Collaboration Guidelines
I emphasize the value of diverse perspectives, encouraging respectful challenges to students' own beliefs and those of their peers. To scaffold class discussions and discourse, and to uphold the values of justice, responsibility, equality, respect, and integrity, I integrate the Ubuntu principles into my syllabi:
These serve as the foundation for the cultivation of an inclusive class culture that promotes knowledge attainment and engagement in collaborative critical thinking, and fosters curiosity in the complexity of the shared human experience.

Importance
•Skin cancer is the most prevalent cancer in the
United States 1
•
In 2016, 82,476 new cases reported and
8,188 people died of Melanomas of the
skin1
Why Sunburn, Why Alcohol?
• •
•
Lifetime sunburn occurrence is the primary risk factor for melanoma 2 An individual’s history of alcohol use has been strongly and
consistently associated with their history of sunburn, and
significantly, to a lesser degree with Melanoma
In contrast to existing literature, this study looks at how
contemporaneous alcohol consumption is directly linked to
sunburn
Research Question What is the relative frequency of sunburn and
contemporaneous use of alcohol in a national sample
of US adults?
Hypothesis 1: Sunburn occurrence will be significantly associated with contemporaneous drinking.
Hypothesis 2: Adults reporting one instance of alcohol-
involved sunburn in the last 12 months will report a higher
number of sunburns.
Adults who reported a history of alcohol-involved sunburn were sunburned 50% more frequently than those who did not.
Alcohol-involved sunburn is more common amongst men.

Results
•Alcohol-involved sunburn in the last 12
months was significantly greater than 0 (6.9%), but not significantly more likely than expected in comparison to other
contexts. (i.e. 10% occurrence by
chance)
•Men (9.5%) were significantly more likely
to report alcohol-involved sunburn in the
last 12 months than women (4.4%)
(p<0.001)
•Young adults (18-34) (8.4%) were more
likely to report an alcohol-involved
sunburn in the last 12 months than older
adults (35+) (5.9%) p = 0.06
•Adults reporting an alcohol-involved
sunburn in the last 12 months averaged
significantly more sunburns (3.07, +/-.48)
than adults without (1.96, +/- .06), F (1,
1457) = 8.96, p < .001
•Men with a history of alcohol-involved
sunburn in the last 12 months had a
much higher average number of
sunburns (3.29) over 12 months versus
not (1.86) whereas mean number of
sunburns was not significantly different
among women (2.17, 2.03 respectively)

Conclusions
Overall, alcohol-involved sunburn does occur among a small, but not insignificant portion of adults sampled.
Adults reporting at least 1 alcohol-involved
sunburn in the last 12 months were sunburned
50% more frequently than those who did not.
•Sunburn and contemporaneous drinking was
•
•
more common amongst men
•Sunburn and contemporaneous drinking was
more common amongst young adults
•Common cooccurring events to alcohol-involved
sunburn include: Swimming, Travelling, Relaxing,
Physical activity, and Trying to get a tan
Other contexts among those reporting a history of sunburn & alcohol use

Environment Influence
•
Engaging with components of nature has been shown to prompt restorative responses, even in urban settings
•
Decr. stress, anxiety, frustration; Incr. positive engagement, cognition, likelihood of PA engagement/achievement 4-6 Responses may be enhanced when PA is performed in the presence of
•
7
restorative spaces
•Previous research has shown that subtle changes in
components of urban design can influence an individual’s
perception and neurological response to their surrounding
environment and PA engagement 8,9
•
E.g. the more restorative components (green space, natural shade, water features, green walls, etc.) the better the outcomes
Theories Considered:
•
: Natural environments can
Attention Restoration Theory
engage involuntary attention allowing for recovery from mental/attention fatigue 6 Stress Reduction Theory: Natural environments can reduce physiological stress and aversive emotion 9
•
Purpose
•
We aim to add to the evidence-base concerning the efficacy of including restorative spaces in urban design to passively enhance population health outcomes—reduced stress and adverse mental health outcomes and improved PA engagement
•
•Arrow 1 shows a park in North Chattanooga—
•
**High-volume open space within view of major urban characteristics versus green space with canopy cover (escape from the city)
The three bridges (A, B, C). The pedestrian-only bridge (A) has the same general view as the other bridges (B, C), but induces more positive mental states (meditation) and less negative responses (anxiety).
despite being mostly green and open, which one would expect to be restorative, anxiety was the dominant mental state.
In contrast, arrow 2, which shows a park that is
close in proximity, participants mental state(s) were meditative dominant, indicating that subtle changes in an individual’s external environment can impact perception and mental state.










Preliminary Analysis
•
Data was Z-scored to account for measurement error and eliminate outliers ArcGIS used to provide visual representation of dominant mental states in response to location
•
Conclusions
•
•
Preliminary Results
•
•
•
•
See the bridge example above to understand/observe how subtle differences in the environment can influence how one perceives relative restoration
Components of the external environment had an observable impact on an individual’s (and the group’s) dominant mental state throughout the respective routes Objectively restorative spaces (water features, green space, etc.) induced positive mental state (Inward Attention, Motivation) Objectively urban characteristics (high traffic, oppressive design, noise) induced negative mental state (Focus, Anxiety)
•
Next Steps
•
Quantify the results using ArcGIS Spatial Analysis
Background
•
•
•
•

individuals
Regular PA (walking) has been shown to mitigate stress and
resulting psychophysiological outcomes 3
•
However, components of an individual’s external environment may influence the net outcome of PA benefit on health

•
•
•
•
Focus: a general measure of mental engagement evidenced by Beta activity in frontal lobe10 Approach Motivation: absence of Alpha Activity in left frontal lobe (frontal asymmetry)—related to high levels of arousal which may indicate + emotion (e.g. happiness, excitement) but could also indicate aggression or anger11 Arousal/Anxiety: high-Beta and Gamma waves in temporal and parietal lobes—commonly associated with tunnel vision and lower long-term performance11 Inward Attention/Meditative State: indicated by Theta waves in frontal and temporal lobes coupled with Alpha waves in the posterior –associated with daydreaming or meditative experiences12
Methods
•
Convenience sample (n=33) of students at the University of Tennessee at Chattanooga in health science courses that encourage active research participation Students were randomly assigned to an approximately 30-minute walking route (daily PA recommendation) in downtown Chattanooga, TN while wearing mobile EEG and activity band (GPS) An iPhone with a custom application used to merge data was carried by all participants
•
•
•
To control for variables, collection occurred at the same time of day, under similar weather conditions
•
Urban social & structural characteristics subdue inhabitants to low-grade stressors requiring directed attention (poverty, traffic noise, oppressive design) resulting in ego-depletion (limiting cognitive capacity) 1
Cumulative effects of persistent low-grade stressors may have a greater influence on overall health status than acute, intense health events 2 As a result, urban-dwellers experience higher levels of stress and are 20-40% more likely to experience anxiety and/or mood disorders than non-urban
Mapping of Dominant Mental States: Chattanooga, TN






Dominant Mental
State
Meditative (Positive)
Anxiety (Negative)
Individual differences in mental state were accounted for by establishing baseline (EEG, HR, HRI) prior to beginning walking route (2018 political ads) and normalizing the data during analysis
Measures and Interpretation
•
EMOTIV Insight EEG: Mental State
•
•
•
•
•
Microsoft Band: GPS location and HR, HRI collection in real time
•
Data collected is displayed alongside brainwave measures to illustrate affect and/or association between location and measures
iPhone: Compiles all data with time points
•
Custom app created to allow compilation of data
into csv file for conversion into an illustrated data
set (seen above)
•
Allows for visual mapping and analysis of
external environment impact on outputs
Implications for urban planning and mental health are evident. Areas with low traffic, better views, more green space, and more canopy cover induce a more positive mental
state (meditative state), whereas construction, traffic, and
distraction induce negative mental states (anxiety). Subtle changes in urban deign (inclusion of restorative spaces/features) can mitigate negative responses
Delta (.5-3Hz) and Theta Waves (4-7Hz): Associated with less intense brain functions (sleep, meditation, daydreaming) Alpha Waves (8-15Hz): Relaxed brain ready for action (walking/running induced relaxed states of mind Beta (16-31Hz) and Gamma Waves (32-100Hz): Associated with greater mental loads (concentration, stress, anxiety)
