The unique aspect of our study was teaching the very fundamentalsof programming simultaneously with the principles and mechanics of refactoring and automatedrefactoring support required to remove code duplication. In particular, the study participants wentthrough a learning experience, guided by an online interactive tutorial that taught them E XTRACTC USTOM B LOCK1 , the refactoring transformation that replaces duplicate code snippets with calls toa
-letter grade scale into the plus-minus system as follows: the minus part of thegrade for the lower 3 points, the whole letter for the middle 3 points, and the plus part for the upper4 points. For example, a B- would be given for scores of 80 to 82.9, a B for scores of 83 to 85.9,and a B+ for scores of 86 to 89.9. However, grades of A+, F+, or F- were not awarded at WSUProceedings of the 2019 Midwest Section Conference of the American Society for Engineering Education 3under the new system. The university has had a grade replacement policy since the mid 1990’s whereby a student canretake a course up to three times, and the most recent grade

process as attending class, taking exams, or reading textbooks.However, the formal exercise of assigning grades only started in the late 18th century.Considering the extensive history of higher education, it is remarkable that the formal markers oflearning assessment have only played their role for a comparatively short period of time. Durm(1993) explains that the first college grades were not of the letter (i.e., A, B, C, D, F) variety.Instead, schools typically used descriptive labels such as Yale College’s optimi, second optimi,inferiores, and pejores system from 1785. Durm attributes the first letter grade system, asroutinely employed today, to Mount Holyoke College in 1897 where an A (95-100), B (85-94), C(76-84), D (75), and E (below 75

To evaluate this hypothesis, a few visualization methodswere implemented in the flipped classroom including:a) Instructor built simple foam models to show design details and potential loadings and stresses.Figure 1 shows sample foam models used in Mechanics of Materials course. The instructordisplays and interacts with the foam models during lectures to visually show deformation andfailure modes. More than 80% of students reflected in SET data that these foam models veryhelpful in their learning. However, they suggested that letting them to interact with the modelswill be more beneficial.

To better observe what is happening at lower altitudes, we can lookat the thrust vs wing loading plane, and the altitude vs thrust loading plane. Changing slope patternscan be interpreted better by looking at 2-D graphs. References1. Petropoulos, B., “Physical parameters of the atmosphere of Venus.

Education, 2020 Assessment of experiential learning in online introductory physics labs during COVID-19 CUNY Queensborough Community College Physics DepartmentAbstractThe sudden COVID lockdown has been a challenge for community college faculty in terms ofpreparation time, restricted mobility and limited resources. On the one hand, the standard face-to-face lab learning outcomes that are used to assess a student’s understanding of the uncertainty,the difference between a “y = ax” versus “y = ax + b” data model, the use of graphical interceptto show systematic error, etc. can be adapted to an online setting when given adequatepreparation time. On the other hand, the essence of online lab teaching must

Our study addressesthis question by measuring motivational constructs in a cohort of mechanical engineering studentsmultiple times across several different course contexts.MethodsData was collected from students in three concurrent Mechanical Engineering courses during theFall 2019 semester (“Course A”: Introductory Fluid Mechanics, “Course B”: Mechanics ofMaterials, and “Course C”: Mechatronics). These three courses have been targeted by ourlearning initiative because they reach every student enrolled in the mechanical engineeringprogram (courses A and B are required while course C is taken by almost all students to satisfy amajor requirement), and because we have
