CORRELATION BETWEEN PROCEDURAL AND CONCEPTUAL TEST IN A STATICS COURSE
(IEEE, 2018-01-01) Restrepo Garcia, Carlos Andres; Barbosa Perez, Jaime Leonardo; Restrepo Ochoa, Jorge Luis; Restrepo Garcia, Carlos Andres; Barbosa Perez, Jaime Leonardo; Restrepo Ochoa, Jorge Luis; Universidad EAFIT. Departamento de Ingeniería Mecánica; Mecatrónica y Diseño de Máquinas
Due to poor performance in Statics at Eafit University, since 2012 the Mechanical Engineering department implemented a virtual tool for the training and assessment of Statics course. Although the implementation led to better performance in the Statics course, students were still showing lack of comprehension of the basic concepts underlying the subject. The department applied a Concept Inventory test to 195 students from the second semester of 2017 in order to check if there was a correlation between the grades obtained in the class examinations and the performance in a conceptual test of Statics. The Concept Inventory was applied one week before the final examination and it was held inside the University facilities. The students were monitored all the time. For the course examinations were taken only three out of the four partial exams, they were computed and then compared to the results of the concept inventory. The results show that almost all the students with the highest grades in the class performed above the mean in the Concept Inventory. The overall mean for the conceptual test was 9.27 and the standard deviation was 5.28. The course grades were discriminated by career and an Analysis of Variance was conducted to determine if there were significant differences among the groups. A correlation analysis suggests that there is not a strong correlation between the course grades and the concept inventory results. One possible explanation for this can be due to the fact that the regular teaching method for these kind of basic courses in engineering in the University is merely procedural and problem-solving oriented, conceptual approaches are often neglected in both teaching and assessment.

Creativity and job tension in experiential learning
(IEEE, 2018-01-01) Pablo Roman-Calderon, Juan; Esteban Acevedo-Jaramillo, Manuel; Esteban Escalante, Juan; Arias, Alejandro; Aguilar-Barrientos, Sara; Barbosa, Jaime; Universidad EAFIT. Departamento de Administración; Estudios en Mantenimiento (GEMI)
This work-in-progress research paper presents a study on employability skills. Employability or soft skills refer to personality traits, attitudes and behavior that are complementary to professional knowledge. These skills are part of a series of competencies that are intertwined with the engineer's technical work [1]. A high percentage of job success depends on employability skills [2]. A gap exists between the attributes of engineering graduates and company requirements [3]. Experiential learning can develop a myriad of skills required by the workplace. Universidad EAFIT, located in Medellin (Colombia), has developed an experiential learning program called KRATOS. KRATOS was sent an invitation to participate in an international competition that implied designing and building a solar/ electric powered vehicle. Think creatively is a competency that is important for engineering practice across areas, disciplines and countries [1]. Although student competitions that include design activities may enhance a passion for engineering, they can also have negative emotional consequences [4] (i.e. job tension). Using the structural equation modeling technique, the authors of this study analyzed the responses of 334 undergraduate students. The results of the study indicate that job tension significantly decreased over time, whereas no significant change was detected in terms of creativity.

DEVELOPMENT OF AN AUTOMATIC PLOTTER FOR GENERATING EXERCISES FOR STATICS COURSE IN ENGINEERING

Departamento de Ingeniería Mecánica; Mecatrónica y Diseño de Máquinas
In the virtual platform for Statics course of Engineering School at EAFIT University it was implemented an automatic plotter for generating exercises to study truss type structures and beams in civil, mechanical and production engineering. Through graphics changes, range of variables and requested questions, the student is provided with different exercises each time that they log in to the platform, achieving the personalization in the learning and evaluation process. The plotters for the structures are developed in JAVA language, and the questions generated are converted into a compatible format with the management learning system MOODLE. Since 2012, the engineering students' population who have enrolled the Statics course is 1909 and all of them have solved exercises generated with automatic plotters. From the design of an automatic generator an unlimited questions bank is obtained to implement in the virtual platform, it allows to get security when applying evaluation tests due to the fact that each person solves a different question. The present study shows the design and programming methodology used to make plotters so it can be extended to others virtual environments in basic sciences. Future works consists in making automatic generators that allow to define difficulty levels to guide the students in a progressive study in the course topics.

RELIABILITY OF A CONCEPT INVENTORY TO DETERMINE THE LEVEL OF STUDENTS IN STATICS

Basic core courses in engineering are often taught and assessed only through procedural approaches, neglecting the conceptual grounds of the subject. In an effort to change that, a Concept Inventory test was applied to 195 students at Eafit University enrolled in Statics. All of the students took the test inside in the campus facilities and were monitored during the whole session to make sure they did not share information. The students took a Computer-Based Test of the Concept Inventory. Three new items were added to the original test of 27 questions, in order to improve the reliability of two specific groups of concepts. For the test was found a mean of 9.7 and a standard deviation of 5.28. For the overall test, the Cronbach's alpha coefficient was 0.81. The psychometric analyses show that all of the items in the test, except one, present an appropriate fit for discrimination and difficulty parameters of the test. Item 26 was deleted when performing the analysis of sub-scales reliability because presented abnormal value for difficulty. For the cluster of Equilibrium, it was seen that deleting this item resulted in an increase of the alpha from 0.2 to 0.36. For the sub-scale of Free-Body Diagram was seen a decrease in the reliability when two new items were added to it. All of the other sub-scales presented good reliability, most of them, above 0.5. The item-person map shows that the overall latent trait of students is lower than the overall test difficulty, meaning that most of the students found the test difficult. One of the conclusion to be drawn from the results is that the students subjected mainly to procedural approaches in teaching, do not perform well in conceptual tests. The results support the claim that Statics can be seen as a collection of concepts that can be clustered in independent groups for teaching.
