Phase diagrams may simply be described as alloying maps in material science. However, the required thermodynamic background knowledge is high level and understanding the cooling procedure of metal melts as well as microstructure of metal alloys is challenging. Common teaching material presents results, but not how to get there and leaves frustrated first year engineering students behind. Knowledge on “how to read” phase diagrams is expected from teachers in advanced courses, but requirements are seldomly met by the students. Teaching phase diagrams in “inverted classroom”szenarios is a method to let the students study the science on their own and then take time to discuss their questions and do extended hands on lectures or exercises in class. Implementing the inverted classroom approach has been proven to be successful in terms of learing outcome, problem solving skills related to phase diagrams and in improving grades. Although the time of preparation is raised by a factor of approximately 4 for 2 four-hour classroom sessions, the positive and sustainable learning outcomes make it fun to teach  and worth the effort.

The objective of this paper is to document the experience of developing and implementing a second-year course in an engineering professional spine that was developed in a first-tier research university and relies on project-based core courses. The main objective of this spine is to develop the students’ cognitive and employability skills that will allow them to stand out from the crowd of other engineering graduates.The spine was developed and delivered for the first time in the academic year 2010-2011 for first-year general engineering students. In the year 2011-2012, those students joined different programs, and accordingly the second-year course was tailored to align with the different programs’ learning outcomes. This paper discusses the development and implementation of the course in the Electrical and Computer Engineering (ECE) department.

As the Bologna Process moves forward, changes in European systems of higher education are expected. The introduction of the ECTS focussing on the students’ achievements described in terms of the learning outcomes and competences acquired is one of the innovations. This process, encouraged by Universidad Politécnica de Madrid, signifies a change in teaching focus, from an input model to an output one, which promotes self-assessment in a flexible curriculum, in this case adapted to student’s language profile. To illustrate this new approach in language learning, a pilot experience with Technical English mining engineering students is discussed, with special attention to learner reflection and self-assessment practices. Students’ progress in self-assessment, based on the introduction of learning outcomes in specific language courses, is analysed to conclude that personal engagement and clear purpose -specified in terms of learning outcomes- seem to have become relevant components to student's self-assessment practice.

Studies in the Tallinn University of Technology are based on a modular system, where geodetic surveying comprises a self-contained study module in the curricula of all civil engineering specialities. Due to geodetic surveying being taught to all first year students of civil engineering, it serves as a touchstone to test a student's suitability for an engineering specialism. Future civil engineers are taught basic geodetic measurements and how to use optical theodolite, levelling instrument and laser level. The paper gives an overview of geodetic surveying lectures, laboratory classes and field survey camp. Teaching and assessment are based on learning outcomes. Students who have passed the exam are allowed to participate in the summer field survey camp, the aim of which is consolidating the knowledge acquired throughout the year and practising teamwork.

At HTW Berlin, Germany first year mechanical engineering students are taught material science as one of the fundamental courses with high work load in a blended learning environment with flipped classroom elements. Therefore peer-to-peer lecture films were established as source of theoretical background knowledge provided for self-study periods. Because the teaching method “inverted classroom” and class results directly relate to the quality of the video material one of the columns of lecture video production is the involvement of students in the lecture film production. First year students directly benefit from their fellow student learning experience, needs and perspective on teaching material. From the lecturers perspective students were generally more active and better prepared during class resulting in better grades. Practice examples introduce and evaluate both, the teaching method and videos.

The teaching of electric circuit analysis traditionally involves problem solving to ensure understanding of analysis theorems, complemented by laboratory experience. When taught to first year Engineering students, this approach lacks a motivational component and presents difficulties due to the weaker mathematics and problem solving skills of first year students. This paper presents a laboratory-centered approach to introduce engineering students to electric devices and systems. Using open-ended design projects, students explore and construct different types of electrical systems. Laboratories are selected so as to develop student intuition in electrical concepts, scientific fundamentals, provide a historical background, and demonstrate systems-level design issues. Over the past three years in our Department, using this approach, increased student motivation and engagement has been observed, supported by a significant increase in Electrical and Computer Engineering enrollment.

Unless we intentionally design teamwork practices within engineering courses, there will be inequity in learning outcomes linked to students’ identity (e.g. specific cultures and gender). In this study we aim to address the inequity of learning outcomes for woman engineering students in a first-year project-based course. We provide evidence that supports this goal and describe four literature-driven best practices for improving teamwork practices: 1. Technical and non-technical roles will rotate.2. Groups will be assigned and will be constrained to not have a gender-solo student.3. Low-stakes, technically oriented icebreakers will accelerate trust-building.4. Teams of students will receive formative feedback on team effectiveness, function and inclusivity.   .

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.

In Mechatronics Engineering at the University of Waterloo, a joint project involving small, inexpensive fuel cells cars was introduced to show how courses in the first term relate to one another. Additionally, the project was designed to provide the students with hands on learning, to give the students a taste of what to expect in later years, and to start incorporating many of the CEAB's graduate attributes at an introductory level. The fuel cell car consists of two low-voltage cells, a low power microcontroller and several sensors mounted on a motorised platform. Students employed concepts from chemistry, programming and mechatronics systems throughout the project, submitting reports at key milestones. during the projet, students needed to make decision in a team environment on which strageties to implement to meet the goals of the project. The project culminated in a final competition and report. Students were surveyed at the start, and end, and the term to measure any changes in attitude with regards to the courses as well as their satisfaction with the project. The project was well recieved by students but significant challenges remain to be solved.
