Comprehensive Dune Study Unit Aligned with Next Generation Science Standards
This project presents curriculum designed for a high school unit focused on Michigan sand dunes. The centerpiece of the curriculum is a field research project that is planned, deployed, and conducted by high school students and teachers so that they can examine changes in local open sand environments. The curriculum is aligned with Next Generation Science Standards and incorporates experimental design, analytical interpretation of data, and real world application of research. This curriculum model begins with the exploration of content, including such background information as the origin of Michigan’s sand dunes, processes that affect sand movement, and seasonal weather patterns in the region. The curriculum includes several modules that prepare students for field exercises along the West Michigan shoreline, including field data sheets and recognition of both dangerous and endangered plants. The fieldwork relies on digital images to capture data at the site. Once students have acquired photos of the field area, they perform data collection and interpretation in the lab. They build as many as several hundred digital images of the site into a panorama that is hosted online, and then analyze changes revealed by comparing panoramas taken at different times during the year using on-screen measurement software and a spreadsheet for data collection and analysis. The real time data the students collect along West Michigan shorelines can be used by public and private institutions to aid in research and restorative practices in order to better understand and protect Michigan’s fragile fresh water dunes and dune ecosystems
Navigating Gender in the Chinese Mission Field, 1920-1949
Immediately after Holland native Tena Holkeboer graduated from Hope College in 1920, she prepared to leave for her first term of service in the mission field at the Reformed Church of America’s [RCA] main mission station in Amoy (now known as Xiamen), China. She was eager to answer the call God had placed upon her heart by pursuing a career in direct evangelistic work, or relational ministry. However, when she arrived in China, her earnest desire to pursue a career in what she believed was her vocation caused her an immense amount of personal turmoil. The career opportunities available to missionaries were determined by their gender and marital status. Thus, while she was certain God was calling her to witness directly to the Chinese people, the RCA’s Mission Board unanimously agreed that as a single female she would best serve God and the people of Amoy as a teacher and a principal in the field of indirect evangelism. At first she struggled to fill these roles, but over her five terms of service in China she came to realize that God was calling her to have a far greater role in His kingdom than she had ever anticipated
Road to Recovery: A Case Study on Lower Back Pain
A significant percentage of the United States population experience or will experience lower back pain within their life. Symptoms can originate from several different pathologies and/or circumstances resulting in a debilitated lifestyle. Many of the people living with pain associated with the lower back are not found within youthful Americans. In this case study, we trace the journey of a 21-year-old collegiate non-athlete across a variety of medical consultations in pursuit of answers to her severe lower back pain. Over a 15-month span, the patient investigated multiple different treatment options and medical opinions in an attempt to decrease the pain she was experiencing in order to return to activities of daily living. Unfortunately no conservative treatment plan produced a resolution in her symptoms and the patient entertained surgical options. Through much consideration, our patient decided to proceed with an Anterior Lumbar Interbody Fusion (ALIF) procedure. This presentation will provide an explanation of the anatomy associated with various common lumbar spine pathologies, as well as an in-depth description of the ALIF procedure
Effects of a Six-Week Static Stretching Program on 40-yard Dash Time, Power, and Flexibility in Collegiate Level Lacrosse Players
Static stretching routines may have the potential to increase power, flexibility, and speed. Therefore the purpose of this study is to determine whether or not performing static stretching over a six-week period will improve 40-yard dash time, vertical jump height, and range of motion in lower extremities for collegiate men’s lacrosse players. To test for this relationship, this study implemented a six-week static stretching routine for male collegiate lacrosse players. Participants in the experimental group were instructed to perform a lower-leg stretching protocol three times a week while the control group did not participate in any stretching. Speed was assessed via a 40-yard dash, power was assessed via a vertical-jump test, and flexibility assessed via a sit and reach test and joint flexibility via goniometer measurements. It was hypothesized that improved power, flexibility, and speed would be seen in the experimental group (six-week static stretching routine) compared to the control group (no stretch). Following the six-week experimental condition treatment, no significant results were found between the two groups. Main effects were found in the vertical jump (p=0.052, pre: 25.5±2.7, post: 24.6±2.9) and the 40-yard dash (p=0.000, pre:5.20±.29, post:5.31±.26). Sit-and-reach showed marginally significant results with an increase in flexibility for the experimental group and a decrease in flexibility in the control group. These results demonstrated the benefit to flexibility a longitudinal static stretching routine has as well as demonstrated that longitudinal static stretching does not improve performance on high power activities
The Effect of Music Tempo on Cycling Performance in Female College Students
Studies have demonstrated that fast tempo music improves performance on the treadmill, however there is a lack of research on this topic using cycle ergometers. This study was designed to determine the effects of music tempo on cycling performance. Participants (n=12) were recruited through word of mouth and completed a maximal oxygen consumption test (VO2 max) on a cycle ergometer. VO2 max results were used to determine resistance for the following trials using 65% of the power output, which was converted to kiloponds. Subjects then completed a familiarization trial that was eighteen minutes including a three-minute warm up. Subjects were told to cover as much distance as possible in the allotted time. The participants completed one trial each week for three weeks, each trial was eighteen minutes including a three-minute warm up, with either fast music (FM), slow music (SM) or no music (NM) playing. Every three minutes throughout the trials heart rate (HR), distance covered, and rate of perceived exertion (RPE) were measured. It was hypothesized that the FM would yield the best performance (the most distance covered). There was no significant difference in distance covered (p=0.431) or HR (p=0.180) at the end of the trials, however SM yielded a significantly lower RPE than FM or NM (p=0.015). The average distance covered in NM was 8.01km±1.43, SM 8.28km±1.54, FM 8.33km±1.38. The average HR in NM was 172.5bpm±19.45, SM 169.58bpm±19.08, FM 159.75bpm±21.77. The average RPE at the end of the trial in NM was 15.33±1.68, SM 14.67±1.61, FM 16±1.68. It was concluded that slow music resulted in a lower perception of effort when covering a similar distance compared to no music or fast music
The Value of Problem Posing in Developing Creatively Gifted Mathematicians
The task of problem posing is often overlooked as a means to develop creatively gifted mathematicians. Silver (1997) suggested that problem posing was an instructional tactic used worldwide to develop creativity in mathematicians. More specifically, Silver advocated that deliberate instructional tactics had to be employed to precipitate creative solutions. Problem posing is often correlated with the aesthetic nature of mathematics.
In this cutting-edge session, participants’ objective is to learn about the value of problem posing through a brief presentation and have an opportunity to generate their own mathematical problem solving tasks given a mathematical concept. The intent is to encourage teachers to consider problem posing as an instructional tactic through having them engage in the experience at this session prior to trying it in their classroom(s). In short, teachers will have a miniature professional development session on what it means to engage students in problem posing
