ABSTRACTIn the case of General Chemistry, many engineering students only take a one semester class with important topics such as kinetics and equilibrium being given limited coverage. Considerable time is spent covering materials already covered in other courses such as General Physics and Introduction to Engineering. Moreover, most GChem courses are oriented toward health science majors and lack a materials focus relevant to engineering. Taking an atoms first approach, we developed and now run a one-semester course in general chemistry for engineers emphasizing relevant materials topics. Laboratory exercises integrate practical examples of materials science enriching the course for engineering students. First-semester calculus and a calculus-based introduction to engineering course are prerequisites, which enables teaching almost all the topics from a traditional two semester GChem course in this new course with advance topics as well. To support this course, an open access textbook in LibreText, formerly ChemWiki was developed entitled General Chemistry for Engineering. Many of the topics were supported using Chemical Excelets and Materials Science Excelets, which are interactive Excel/Calc spreadsheets. The laboratory includes data analysis and interpretation, calibration, error analysis, reactions, kinetics, electrochemistry, and spectrophotometry. To acquaint the students with online collaboration typical of today’s technical workplace Google Drive was used for data analysis and report preparation in the laboratory.

This study was conducted to examine how first-year engineering students conceptualize the Entrepreneurial Mindset (EM) and how that conceptualization changes over the course of their first semester of college, using the Kern Entrepreneurial Engineering Network (KEEN)’s 3Cs as a starting point. Students enrolled in an introductory, multidisciplinary design course responded to biweekly reflection prompts on their educational experiences (either in high school or as a first-year college student) and related this experience to one of the 3Cs of EM: Curiosity, Connections, or Creating Value. Results indicate that students’ conceptualization of the 3Cs often align with definitions of EM from KEEN, as well as foundational works in the entrepreneurship field, and that their interpretation of each of the 3Cs does change during their first semester in college. For instance, students were less likely to write about curiosity and more likely to write about creating value at the end of the semester compared to the beginning.

The undergraduate degree in Industrial Engineering at the Faculty of Technology (FT) of the Federal University of Amazonas (UFAM) completed 15 years in the first semester of 2019. During this period, enrolled 837 students, of which 238 (28%) have already graduated, 335 (40 %) continue to study and 263 (32%) have left the course. Given this percentage of dropout and the need to research more about the topic, this article aims to investigate the main causes of abandonment in this course in order to propose strategies to minimize the problem. The method used was the Survey, which applied a five-part electronic questionnaire sent to 203 dropout students who had e-mail. After analyzing the answers of 39 (19.21%), it was concluded that most students did not receive vocational orientation before joining the University and the main reasons that influenced the students to quit the course were the didactic-pedagogical deficiency of the teachers, the difficulty in conciliating study and work, and the course did not satisfy their expectations.

The added value in education refers to the contribution that the educational institution effectively makes to student learning, expressed as the growth in knowledge, skills and abilities, in a period of time, as a result of their educational experience. The objective of the research is to determine the added value of the academic work of the Universidad Francisco de Paula Santander in the development of physical- mathematical thinking in engineering students and the estimation of a mathematical model that allows its valuation. In model allows analyzing the trajectory of the group of engineering students who entered in the first semester of 2018 and involves endogenous and exogenous variables associated with the process. The research is framed in the quantitative paradigm, descriptive, multivariate and correlational. We work with two types of data, the secondary data are constituted by the students’ grades in 2018 and 2019, this information may present biases because they are different courses with different teachers, however, it allows to see the evolution of students in calculus, statistics and physics courses. Primary data were obtained from a test applied in 2018 and a similar test applied in 2019, graded using item response theory. Results were compared and differences were evaluated to estimate the contribution effectively made by the university.

This study focused on the behavior of road user (biker/rider), especially around the Gendengan Intersection in Surakarta. This study aims to determine the types of violations, the causes, and effects that occur around the intersection. The primary data used are observation data of violations and questionnaires of 400 respondents. This study also uses data of traffic accidents and violations from the SATLANTAS of Surakarta Police and the IRSMS of KORLANTAS POLRI. The analysis refers to Law No.22 of 2009. Based on the Police data analysis, there are 87.98% of violations in Surakarta related to driver behavior, while using the primary data it was found around 48.32%. Lack of awareness of orderly traffic causes the driver to ignore his safety. This can be seen from the percentage of respondents who answered YES greater than NO happening in almost all violation types. Traffic violations can be a major factor in traffic accidents. Therefore, the implementation of strict rules needs to be done for those who violate, either in the form of fines or imprisonment. Penelitian ini difokuskan pada perilaku berlalu lintas pengendara di jalan, khususnya di sekitar Simpang Gendengan Surakarta. Penelitian ini bertujuan untuk mengetahui tipe-tipe pelanggaran, penyebab dan dampak pelanggaran yang terjadi di sekitar simpang tersebut. Data primer yang digunakan adalah data pengamatan lapangan dan kuesioner dari 400 responden. Penelitian ini juga menggunakan data kecelakaan dan pelanggaran lalu lintas dari Satlantas Polresta Surakarta dan IRSMS KORLANTAS POLRI. Analisis mengacu pada Undang-Undang No.22 Tahun 2009. Berdasarkan hasil analisis data Kepolisian diperoleh 87,98% tipe pelanggaran di Surakarta berkaitan dengan perilaku pengemudi, sedangkan dari data primer diperoleh sebesar 48,32%. Kurangnya kesadaran akan tertib berlalu lintas menyebabkan pengemudi pengabaikan keselamatannya. Hal ini terlihat dari prosentase responden yang menjawab Ya lebih besar dari Tidak terjadi hampir pada semua tipe pelanggaran. Pelanggaran lalu lintas dapat menjadi faktor utama kecelakaan lalu lintas. Oleh karena itu, penerapan aturan yang ketat perlu dilakukan bagi yang melanggar, baik berupa hukuman denda atau penjara.

How can we merge interactive design processes and the development of interactive prototypes for first-semester students without prior programming experience? The authors provide a selection of relevant contructionism-inspired programming tools and provide indications on how one of them can enrich a user-centred design project for first-semester software and IT engineering students. They do this by describing the experiences from two runs of a HCI course and the concurrent semester projects. The students developed interactive touch-based learning apps for children in the fourth to sixth grade using App Inventor. Most of the project groups managed to do three iterations of specifying requirements, doing conceptual design, physical and interactive prototyping, and user evaluation. The groups implemented quite complex programs with multiple-screen switching, multiple interfaces, media such as pictures, animations and sound, database connection, Web-server connection, and integrated sensors, such as camera, accelerometer, etc. The students did a lot more project iterations and spent more time on the creative designs in real-life situations than the authors expected. This also allowed for the students' professional reflections on their prototypes, usability, interaction, and the design processes. All in all, this gave them a more profound real-life experience in the user-centred design process. The authors compare the two runs and suggest how to introduce contructionist prototype programming in a HCI course curriculum and conclude that contructionist programming tools can be a valuable addition to the teaching of HCI, and they suggest that further research should be conducted to explore how to best integrate these tools in order to optimize the students' learning capabilities.
