Throughout the study period the instructors used the same course materials and metregularly to ensure that course content and delivery were aligned.The traditional method relied on in-class lectures to deliver new content to the students and classperiods utilized active-learning practices to enhance this delivery. Lectures typically took the form ofpower point slides that the instructor would talk through. The slides frequently included examples andactivities that the students would be asked to work through with a partner before moving on. Therewere no pre-class activities required and homework and projects were regularly assigned to be

The camp is advertised tostudents who registered for the fall offering of the MEB course at a minimal cost to the student(~$25). The camp was designed to occur after campus move-in, but just before the start of fallclasses. The workshop includes team-building exercises, hands-on projects, a lab tour,presentations from faculty and upper-level students about upcoming classes, the curriculum

education helps with parents’ perceptions about their ability to support their children.Blacks are overrepresented in many sports, and consequently sports and entertainment aregenerally seen as pathways to success. As a result, parents usually place more emphasis ongetting their children involved in afterschool and weekend sports activities versus educationalprograms [4], [5], [6]. When parents do pursue educational programs for their children, theyencounter additional obstacles. Many families have difficulty supporting their children’sparticipation in educational programs due to changing work schedules and constraints such aspublic transportation and the cost to participate.This project will inform our understanding of how parents from

Aliyu7 noted thathydropower plants could not be relied upon. He stated that the oscillatory nature of energy outputfrom hydropower plants (mainly due to seasonal changes) and the negative impacts experienceddue to climate change are decreasing the water levels required to run the hydropower plants. Thedilapidated state of the hydropower infrastructure also reduces significantly their energy outputwhen compared to their projected capacity. The thermal plants utilize mostly natural gas as feedfuel and the lack of adequate natural gas
