When you experience stress, your Hypothalamic Pituitary Axis stimulates the pituitary gland to secrete adrenocorticotropic hormones ACTH. ACTH then stimulates the adrenal glands to produce the hormone cortisol helping the body to maintain steady supplies of blood sugar to help you cope with prolonged stress and then helps the body to return to normal.
While your stress response system helps you perform under pressure, it was not designed for prolonged time periods. Constant stress at work keeps your cortisol levels high, which leads to several physical issues that kill your productivity, including sleep disorders, constant fatigue, anxiety and lower immunity. A global work survey found that stressed employees took double the sick days of less-stressed employees. In , a group of Korean scientists studied the effects of stress on the musculoskeletal system of hospital workers.
Those that were more stressed were more likely to suffer from minute damage to their muscles and skeletons that accumulate over time, leading to them needing more time off work to recover. Here are a few ways you can counter those stressful moments at work:.

Dopamine-Producing Diet. The instructors were dissatisfied about the wide breadth of topics in the course and wished to move toward teaching fewer topics in greater depth. We also rearranged the material. So they [the lectures] used to be in a taxonomic orientation, I would give a whole lecture titled the biology of fungi, and the students complained that this taxonomic focus seemed to resemble the structure of BSCI [the prerequisite course]. I decided to explode those taxonomic lectures, and take the bits of content that I still thought were valuable, and spread them into other parts.
So for example the stuff on mating types, which is wacky and interesting to me, and I hope to the students, is now in a lecture on sex. Alex noted,. All these attributes of their biology have to function simultaneously on several different spatial and temporal scales … if we think they do, then we continually miss things that otherwise would fall out naturally if we were a little less wedded to our disciplines. Relatedly, the instructors noted that most students enrolled in BSCI without having taken introductory physics or chemistry, which they thought was preventing students from drawing upon highly relevant concepts e.
Underrepresented groups do poorly in traditional classes. The instructors quantitatively examined student performance for specific student subgroups i. Coupled with the science education literature documenting the ability of active learning to help underrepresented groups Preszler, ; Haak et al. In Fall , the instructors went through the process of course revision that follows the adapted model by Rogers and Andrews and Lemons ; see Figure 1.
In the following sections, we discuss their progression through the innovation-decision model. Table 1 shows a summary of the change process for the Fall semester. Before the Fall semester, the instructors engaged in several efforts to increase knowledge about evidence-based teaching approaches to modify the course. The knowledge sources were as follows:. Consultation with discipline-based education research experts and FLCs. For example, Julie participated in a physics education FLC to learn about how students learn and to learn strategies to incorporate physics into biology i.

I will go ask [physics education professional] questions. Reading the science education literature. As a new instructor, Julie participated in the college workshop for new instructors. The workshop was led by the director of the teaching and learning center, who provided several resources for using evidence-based teaching approaches, including an article giving an overview of learning styles Felder, , a book on teaching tips McKeachie and Svinicki, , and the book Scientific Teaching Handelsman et al. Observing other instructors teaching. This pilot implementation was successful, and the instructors were interested in investigating whether the learner-centered teaching model used could be scaled up to a large-enrollment class.
Following the knowledge-generation phase, the instructors felt prepared to change their teaching to a more learner-centered teaching style. They decided to conduct a comparative experiment during the first implementation of the GAEs i. GAE classes; see Marbach-Ad et al. Although the instructors were aware of the literature documenting the effectiveness of learner-centered teaching, they had several reasons to execute the experiment:.
Obtain evidence for overall effectiveness. The instructors were unsure whether their activities were the best way to change the course e. The instructors also wished to explore cost-effectiveness, since they knew that changing the course would require a high instructor time commitment. Convince colleagues to adopt learner-centered teaching approaches.
Respond to grant award requirements. As mentioned earlier, the institution announced a call for proposals for instructors to revise their teaching. The instructions required applicants to propose comparative experiments during course revision to document effectiveness. As proposed in the provost grant application, the instructors executed the comparison study. In the traditional class, instructors delivered a minute lecture three times per week. The GAE consisted of a brief minute introductory lecture a short version of the lecture presented to traditional class students and a minute group activity.
This difference was coincidental and went unnoticed until analysis of study data. Just in numbers alone but not necessarily mass , a. This problem-solving phase provided opportunities for students to explore the affordances and constraints of multiple solutions. The other Kingdoms listed are either not multicellular or not autotrophic. A reason is a motive or cause for something—a Definition: what are critical justification for thoughts, actions, or opinions. These areas are called biomes, and because they include the relationships of many organisms and physical factors, they are also ecosystems.
As scientists, the instructors wished to manipulate the addition of the GAE day only and to keep remaining variables constant across classes. Therefore, homework assignments, examinations, optional computer tutorials, and office hours availability were consistent in both classes see Table 2. In the GAE class, on the day of the GAEs, students were instructed to sit with groups of three to five students of their own choosing and to leave empty rows between groups.
Students were asked to have at least one laptop per group. As discussed previously, the GAEs were designed to be more learner centered relative to traditional lecture classes. They built that relationship in a way that otherwise I would have just told them. Following the Fall semester, the instructors reflected on the various pros and cons of the learner-centered teaching intervention in the interviews. Observers and students also provided feedback that was used by the instructors to reflect on both sections of the course and on the comparative experiment.
Several themes emerged from these data:. Changed role of the instructor. The instructors described how the role of the instructor changes from someone who lectures the students to someone who facilitates and advises the students during their learning process. My role was partly just to control the chaos sometimes, and to control that the TAs had the information they needed so they could provide guidance to the students.
