The course ‘Introduction to Engineering Design’ is aimed at freshmen students entering Mechanical and Aerospace engineering. The course was restructured from its previous 3-credit lecture format to a 2 credit lecture coupled with a new 1 credit design laboratory. The laboratory project aims at giving the students experience in professional design, engineering practice, and teamwork. While the lecture presents an overview of the engineering profession and its practices, small student teams conduct a structured hands-on design project in the lab. The team assignment is the design, programming, and testing of autonomous mobile ‘Sumo’ robots. Each team develops and builds an autonomous robot, which will compete against the other teams’ robots at the end of the semester. Students find the robot project highly motivating and spend voluntarily several afternoons weekly working in the lab. Student enrollment has increased more than five-fold since course inception six years ago. The course is also being taught regularly to seniors at local high schools through distance education, further broadening the pool of future engineering students. The paper describes the lab course structure, organization, and student learning outcomes.

The problem in this study is that students are less interested in learning and seen from the daily results obtained from SMAW subject teachers that the learning outcomes of SMAW subjects in the Welding Engineering department are still low. The purpose of this study is to determine whether there is a relationship between interest in learning and learning outcomes in SMAW subjects. This type of research is descriptive correlational research. The sample stated in this study were all students of class XI of the Welding Engineering Department who participated in the 48 Solid Metal Arc Welding subjects. The results of the study revealed a contribution of a positive relationship between interest in learning with student learning outcomes in the field of study SMAW Class XI Welding Engineering students of SMK Negeri 1 West Sumatra 2018/2019 learning year. This gives the meaning of the higher interest in learning, the higher learning outcomes of SMAW learning outcomes.

Empirical studies suggest that practical intelligence acquired in engineering laboratories is valuable in engineering practice and could also be a useful learning outcome that is a result from a laboratory experience. To prove this, the author started a project to understand further about the practical learning outcomes from traditional laboratory classes. When tools used by psychologists were applied to measure practical intelligence in an electronics laboratory class, not only could a significant gain in hands-on practical intelligence be measured, but students’ ability to diagnose equipment faults could also be predicted. For the first time, therefore, the author can demonstrate that there are real advantages inherent in hands-on laboratory classes, and supported by Outcome Based Education (OBE) method, it is possible to measure this advantage. It is possible that measurements of practical intelligence may reveal new and more powerful ways for students to acquire practical knowledge. The results firstly demonstrate the ability to devise effective ways to assess the outcomes of practical intelligence acquired by engineering students from their laboratory experiences. The results from the study show that the score on practical intelligence outcomes is proportional with the outcomes of the ability in diagnosing equipment faults. Therefore, the novel results suggest that practical intelligence scores predict the ability to diagnose experiment faults for similar laboratory equipment.

This learning innovation article’s purpose is to provide educators with a course assessment tool that can be used to improve student outcomes in an undergraduate, production innovation, and development course, comprised of cross-functional teams (business and engineering students). We demonstrate how over a period of three years, we used the assessment tool to help make course changes that would influence student learning outcomes. In addition, we illustrate how the tool helped us to focus on particular student skills, make specific changes targeted at selected skills, and measure if these course changes were effective with engineering student outcomes.

The purpose of this study was to determine the differences in students' mathematics learning outcomes who were taught using the STAD learning model and the TGT learning model on triangles and quadrilaterals (In Grade VII Even Semester 2014-2015 Academic Year at SMP Muhammadiyah 31 East Jakarta). The method used is the experimental method. The material tested is about triangles and quadrilaterals. Before being used to collect respondent data, a test test was carried out first and the validity was calculated using the Biserial Point Correlation (rpbis). Calculation of the validity of the instrument on triangle and quadrilateral material obtained 26 valid questions and 14 invalid questions, while the reliability was calculated with KR-20 which was 0.948. It means that the reliability is high. Based on the calculations obtained data that the average student learning outcomes through the STAD learning model has an average of 61.70 standard deviations, 11.06 medians, 64.6 and the mode is 61. Furthermore, the TGT learning model has an average of 71.84 standard deviations of 12, 01 median 78 and mode 64. Hypothesis testing using t-test is obtained t = 2.98 at a significant level of 0.05 and dk = 46 t = 1.67 because t t is 2.98 1.67 so it can be concluded that there are differences in the mathematics learning outcomes of students who are taught using the STAD learning model and the TGT learning model in solving problems on triangle and quadrilateral material. ABSTRAKTujuan dari penelitian ini adalah untuk mengetahui adanya Perbedaan hasil belajar matematika peserta didik yang diajarkan menggunakan model pembelajaran STAD dan model pembelajaran TGT pada materi segitiga dan segiempat (Di kelas VII Semester Genap Tahun Pelajaran 2014-2015 Di SMP Muhammadiyah 31 Jakarta Timur).

Online homework systems are being increasingly used for auto-graded, instant feedback homework and practice for students in math, science and engineering. Students may use these systems, which often allow multiple or unlimited tries, in ways that are different from completing traditional paper-based homework, however research relating online homework system patterns of usage and learning outcomes is limited. This study explores online homework submission patterns and their links to student learning outcomes (weighted individual grades) by analyzing the submission patterns of two second-year engineering courses (~130 students each) from our institution over the 2017-2018 academic year using WeBWorK, an open online homework platform. Students in each of the two courses were clustered into three groups using a K-means algorithm based on when during the homework period they tended to submit attempts. Clusters were used to approximately represent a submission pattern, meaning groups of students that submit attempts mostly early, mostly late, or more evenly over the period. Conducting one-way ANOVAs for each course, we found that there is a significant difference between clusters (submission patterns) in terms of mean individual weighted grades on tests and exams (p < 1.07e-08, p < 2.68e-5). Post-hoc analyses revealed that the best performing cluster (students who submit attempts mostly early) had a mean tests/exams grades that were about 10% higher than worst performing cluster (students who submit attempts mostly late) (p < 2.6e-06, p < 9.9e-05).
