Emerging cad and bim trends in the aec education: An analysis from students\u27 perspective

As the construction industry is moving towards collaborative design and construction practices globally, training the architecture, engineering, and construction (AEC) students professionally related to CAD and BIM became a necessity rather than an option. The advancement in the industry has led to collaborative modelling environments, such as building information modelling (BIM), as an alternative to computer-aided design (CAD) drafting. Educators have shown interest in integrating BIM into the AEC curriculum, where teaching CAD and BIM simultaneously became a challenge due to the differences of two systems. One of the major challenges was to find the appropriate teaching techniques, as educators were unaware of the AEC students’ learning path in CAD and BIM. In order to make sure students learn and benefit from both CAD and BIM, the learning path should be revealed from students’ perspective. This paper summarizes the background and differences of CAD and BIM education, and how the transition from CAD to BIM can be achieved for collaborative working practices. The analysis was performed on freshman and junior level courses to learn the perception of students about CAD and BIM education. A dual-track survey was used to collect responses from AEC students in four consecutive years. The results showed that students prefer BIM to CAD in terms of the friendliness of the user-interface, help functions, and self-detection of mistakes. The survey also revealed that most of the students believed in the need for a BIM specialty course with Construction Management (CM), Structure, and Mechanical-Electrical-Plumbing (MEP) areas. The benefits and challenges of both CAD and BIM-based software from students’ perspectives helps to improve the learning outcomes of CAD/BIM courses to better help students in their learning process, and works as a guideline for educators on how to design and teach CAD/BIM courses simultaneously by considering the learning process and perspectives of students. © 2018 The autho

Improvement or selection? A longitudinal analysis of students' views about experimental physics in their lab courses

Laboratory courses represent a unique and potentially important component of the undergraduate physics curriculum, which can be designed to allow students to authentically engage with the process of experimental physics. Among other possible benefits, participation in these courses throughout the undergraduate physics curriculum presents an opportunity to develop students' understanding of the nature and importance of experimental physics within the discipline as a whole. Here, we present and compare both a longitudinal and pseudo-longitudinal analysis of students' responses to a research-based assessment targeting students' views about experimental physics -- the Colorado Learning Attitudes about Science Survey for Experimental Physics (E-CLASS) -- across multiple, required lab courses at a single institution. We find that, while pseudo-longitudinal averages showed increases in students' E-CLASS scores in each consecutive course, analysis of longitudinal data indicates that this increase was not driven by a cumulative impact of laboratory instruction. Rather, the increase was driven by a selection effect in which students who persisted into higher-level lab courses already had more expert-like beliefs, attitudes, and expectations than their peers when they started the lower-level courses.Comment: 6 pages, 1 figure, submitted as a short paper to Phys.

From Gatekeeping to Engagement: A Multicontextual, Mixed Method Study of Student Academic Engagement in Introductory STEM Courses.

The lack of academic engagement in introductory science courses is considered by some to be a primary reason why students switch out of science majors. This study employed a sequential, explanatory mixed methods approach to provide a richer understanding of the relationship between student engagement and introductory science instruction. Quantitative survey data were drawn from 2,873 students within 73 introductory science, technology, engineering, and mathematics (STEM) courses across 15 colleges and universities, and qualitative data were collected from 41 student focus groups at eight of these institutions. The findings indicate that students tended to be more engaged in courses where the instructor consistently signaled an openness to student questions and recognizes her/his role in helping students succeed. Likewise, students who reported feeling comfortable asking questions in class, seeking out tutoring, attending supplemental instruction sessions, and collaborating with other students in the course were also more likely to be engaged. Instructional implications for improving students' levels of academic engagement are discussed

Does choice of programming language affect student understanding of programming concepts in a first year engineering course?

Most undergraduate engineering curricula include computer programming to some degree,introducing a structured language such as C, or a computational system such as MATLAB, or both. Many of these curricula include programming in first year engineering courses, integrating the solution of simple engineering problems with an introduction to programming concepts. In line with this practice, Roger Williams University has included an introduction to programming as a part of the first year engineering curriculum for many years. However, recent industry and pedagogical trends have motivated the switch from a structured language (VBA) to a computational system (MATLAB). As a part of the pilot run of this change,the course instructors felt that it would be worthwhile to verify that changing the programming language did not negatively affect students’ ability to understand key programming concepts. In particular it was appropriate to explore students’ ability to translate word problems into computer programs containing inputs, decision statements, computational processes, and outputs. To test the hypothesis that programming language does not affect students’ ability to understand programming concepts, students from consecutive years were given the same homework assignment, with the first cohort using VBA and the second using MATLAB to solve the assignment. A rubric was developed which allowed the investigators to rate assignments independent of programming language. Results from this study indicate that there is not a significant impact of the change in programming language. These results suggest that the choice of programming language likely does not matter for student understanding of programming concepts. Course instructors should feel free to select programming language based on other factors, such as market demand, cost, or the availability of pedagogical resources

Improving Underrepresented Minority Student Persistence in STEM.

Members of the Joint Working Group on Improving Underrepresented Minorities (URMs) Persistence in Science, Technology, Engineering, and Mathematics (STEM)-convened by the National Institute of General Medical Sciences and the Howard Hughes Medical Institute-review current data and propose deliberation about why the academic "pathways" leak more for URM than white or Asian STEM students. They suggest expanding to include a stronger focus on the institutional barriers that need to be removed and the types of interventions that "lift" students' interests, commitment, and ability to persist in STEM fields. Using Kurt Lewin's planned approach to change, the committee describes five recommendations to increase URM persistence in STEM at the undergraduate level. These recommendations capitalize on known successes, recognize the need for accountability, and are framed to facilitate greater progress in the future. The impact of these recommendations rests upon enacting the first recommendation: to track successes and failures at the institutional level and collect data that help explain the existing trends

STEMteach: Preparing the Next Generation of Mathematics and Science Teachers

With an increasing demand for individuals prepared in Science, Technology, Engineering, and Mathematics (STEM), one university responded to this call by changing its teacher preparation program. Better-prepared mathematics and science teachers have the opportunity to engage and excite students, thereby preparing and promoting more of them to enter the STEM professions. The described program is a replication of the national UTeach model that recruits content majors in mathematics and science to explore the teaching profession during a first-semester course that includes an early field experience in the elementary grades. This field experience is designed to be engaging for both the teacher education candidates and the elementary students in an effort to demonstrate the joy of teaching and to retain the candidates in the program. The ultimate goal of the program is to increase the production of quality secondary mathematics and science teachers who can transfer their own deep understanding of their content to students so that these students will be career and college ready in the STEM disciplines

The Current Generation of Integrated Engineering Curriculum

In September of 2004 our university adopted the Multidisciplinary Engineering Foundation Spiral Curriculum as the basis for disciplinary engineering programs in Chemical, Civil, Electrical, Mechanical and General Engineering. The curriculum includes a sequence of first and second year engineering courses, matched closely with the development of students’ mathematical sophistication and analytical capabilities and integrated with course work in the sciences. Students develop a conceptual understanding of engineering basics in this series of courses which stress practical applications of these principles. The new curriculum was designed to provide students with a multidisciplinary perspective while developing basic engineering skills and fostering an understanding of basic engineering concepts. Each of the ten courses in the program were developed and are taught by faculty from several disciplines. Course materials are intended to make students keenly aware of the highly integrated nature of the current practice of engineering. It was also expected that the novel program would prove to be attractive to a broader range of students than those drawn to traditional disciplinary programs. Finally, student retention was expected to be enhanced by the new courses. Students who entered as freshmen in 2004 are currently juniors, taking courses in their disciplinary major. This study attempts to provide early data on the success of the program through the following measures: • Impact of the new curriculum on student recruiting through a survey of newly matriculated students • Impact on student retention from first to second and second to third years • Comparison of student performance in early disciplinary courses with that of students in previous years • Impact of program implementation on faculty attitude

A Systematic Review of Mechatronic-based Projects in Introductory Engineering and Technology Courses

For well over two decades, engineering and technology educators have been deploying hands-on project-based learning activities in freshmen courses, in the hopes of inspiring students,increasing retention, and creating better educated graduates. Some of these educators have also been reporting the results of their efforts through papers published and/or presented in a widevariety of settings. In an attempt to understand the broad results of these efforts, this paper discusses the effects of mechatronic-based projects on the retention of engineering and technology students. To facilitate this discussion, we conducted a systematic review of well over 120 related sources of literature spanning the years from 1990 to 2014. This effort constituted a configurative review and allowed us to construct a methodically mapped landscape of the topicby applying a code or codes to each source. We will present the results of this effort, including abulations of the works that allow identification of the trends and gaps in the literature specific to the categories of Course Level, Content Delivery Method, Retention, Investment Level/Duration, Improvement Process, and Pedagogy. We will discuss our categorization strategies, and present conclusions about the efficacy of these approaches and the areas that appear most fruitful for additional research. In so doing, we hope to lay a strong foundation for future efforts towards improving the education of freshman technology students at a large land-grand, research-based university in the United States

Opportunity to Learn Audit: High School Science

It is widely acknowledged that today's students will need to compete in a global economy that requires proficiency in science and technology. In an attempt to ensure that all Massachusetts students reach a minimal level of proficiency in these subjects, the class of 2010 high school students will have to earn a passing score on one MCAS science exam (biology, chemistry, physics, or technology/engineering) in order to receive a diploma. Results of national assessments show that while Massachusetts students score better in science than their peers in other states, there are disturbing gaps in the performance of certain sub-groups of students -- black and Hispanic students, students from low-income homes, English language learners -- who fail to meet proficiency standards at satisfactory rates. Indeed for all students, undeniable gaps exist in students' achievement, knowledge, expectations and comprehension of the needs of the future economy. Given that the state is now holding all students accountable for their performance in science, it is necessary to examine whether or not all students are receiving equitable opportunities to learn and succeed in science. This report seeks to identify concretely what top-performing schools do to support science instruction and to draw out considerations for policymakers at the district and state levels.Themes across the SchoolsThe following is a description of greater opportunities to learn science that are present in top-performing schools, compared to low-performing schools:More science teachers.Well-prepared teachers.More teacher preparation time.Financial resources.Material resources.Options for placement in science courses.Real-world application.Enrichment opportunities in science.Science related partnerships with universities.Peer tutoring.Policy ConsiderationsFor school and district leaders:Encourage and support science-related professional development.Provide incentives for highly qualified science teachers to teach in your schools.Structure the school day to enable more teacher preparation time.Develop partnerships with neighboring universities.Institute peer tutoring programs.Institute formal remediation and academic support programs for students struggling in science.Look outside the school for people to lead extracurricular activities.Make well-equipped science classrooms a priority.For state policymakers:Providing additional resources and ensuring that all high school students in Massachusetts have opportunities to learn science and to achieve at high levels will require coordinated efforts by both state legislators and the Department of Elementary and Secondary Education. The following are recommendations for consideration by both state legislators and the Department.Provide incentives for highly qualified science teachers to teach in low-performing schools.Provide incentives for science professionals to enter the teaching profession.Continue to support expanded learning time initiatives.Support enrichment opportunities for low-performing schools.Broaden current state-level science initiatives to encompass all grades from kindergarten through higher education.Provide a supplementary materials budget to under-resourced schools.Provide support for formal remediation and academic support programs for students struggling in science
