Published: March 2023

International accreditation norms like Washington Accord or the national norms like NBA have defined program outcomes for undergraduate professional engineering courses. These norms aim at the holistic development of students. This paper presents project-based learning as a strong pedagogy tool for the overall development of students. The undergraduate project course is considered a case study for this pedagogy technique and the attainment of Program outcomes is illustrated in the results. The major desired outcomes for project work like communication, collaboration, knowledge application, documentation, work ethics, teamwork and independent learning are the parameters included in the Program Outcomes. The three point Likert scale is used for the assessment of the program outcomes. The results show that most of the program outcomes for these courses are satisfactorily achieved. Thus, it can be established that project based learning techniques help inculcate specific knowledge, skills and attributes into the students thereby assisting their holistic development and growth.

To engage the students actively in large classes is a challenging task. It became tougher especially in the online mode of conduction of lectures, due to the pandemic situation. In the absence of physical classroom interaction, students tend to lose focus and disconnect with the course content. It is observed that implementation of active learning techniques, helps in enhancing students’ engagement. It also appears to be beneficial in improving attainment levels of the course outcomes which is a very important aspect of the outcome based education. This paper discusses Peer Review as an active learning strategy, implemented for the course of Basic Electrical and Electronics Engineering for the first year engineering students. The students were divided into small groups, were asked to solve problems (were given a task based on a course outcome) and were asked to Peer Review the work with the help of assessment rubric provided. Course outcome where Peer Review Technique was implemented is compared with the other course outcomes where this technique was not implemented.

The young (millennial) learners are not particularly motivated only by traditional classroom-based, one-way presentation/ lecture-based approaches as they are exposed to digital lives. Furthermore, in an outcome-based education system, all features of teaching focus on course outcomes. Therefore, the teachers face the challenge of student engagement. The work in this paper is regarding the active learning method for the final year students of the ‘Information and Cyber Security' course. In this activity, the students design (in a group of 2) and build the game using the software platform of their choice. The game is built around the CIA triad (privacy, integrity. and availability), network security concepts and protocols. After designing and building the prototype of the game, the students for assessment and feedback play the game with their class mates and the faculty members. Then classmates and teachers give scores for each core drive on the Octalysis tool. This helps student game designers to improve the weak core. Octalysis is a gamification framework designed as an octagon shaped with 8 core drivers representing each side. The entire exercise is stimulating and motivates the students as indicated in their feedback of the students (68% of students rated excellent). Gamification by students proved to enhance student learning by promoting critical thinking and problem-solving skills, as evident from the assessment. Finally, course coordinator evaluates the game using rubrics that were shared with students beforehand. The evaluation rubric focuses on the title of the game, content, creativity, rules, instructions of the game, and cooperative efforts. Game design and implementation by students activity proves that the greatest benefit is that the maximum learning happens in the design process (for game designers) compared to players. Further, the students also learn to work in groups and solve problems. Furthermore, the most significant of the entire activity is learning of cyber security concepts and protocols in a fun way.

Increased levels of communication and automation process indicates the onset of fourth Industrial Revolution. Production of industry ready professionals especially for the dynamic Civil Engineering domain will be an outcome of continuous implementation of interactive teaching-learning methods. Incorporation of industry-based experiential learning to supplement the classroom sessions have been attempted for two undergraduate courses in Civil Engineering programme namely Surveying and Computer Aided Building Drawing for first year learners. Simultaneously, conventional and standalone classroom teaching was implemented for the second year learners with respect to these two courses. This study attempts to compare and analyse the learner perceptions and measure the learning outcome attainment of the Industry based Experiential learning and conventional teaching method. The selected courses provided ample space and scope for the working of industrial methodologies such as use of modern laboratory equipment (Total Station) and software (AutoCAD) for real-time problems. The assessment patterns varied extensively between the two teaching methods as the first year learners had experimental assessments for solving critical scenarios in the construction site. The results and analysis of learners’ perception obtained through the internal assessments provided an insight that Industry based Experiential Learning was well ahead in the development of Industry ready professionals. However, the challenges in this novel method are also accounted for future adaption for other courses. Hence, this study provided a unique opportunity to compare and contrast the learning environments and identify specific benefits for both the teaching methods.

This paper presents an experimental study conducted on employing Active Learning strategies towards enhancing the attainment of learning outcomes of a course "Linear Control Systems" in the undergraduate (UG) Electrical and Electronics Engineering (EEE) programme. The existing UG programme curriculum is retrofitted into outcome-based curriculum. The Programme Outcomes (POs) for this programme are derived from the Graduate Attributes of Washington Accord (WA). In order to meet the POs, Course Learning Outcomes (CLOs) are written predominantly in the Cognitive (Revised Bloom's taxonomy) and Psychomotor (Dave's taxonomy) domains for lecture-based courses and laboratory courses, respectively and very few are written in Affective (Bloom's taxonomy) domain. In this paper, four CLOs (i) Discuss the various classification of control systems (K2), (ii) Define the time and frequency response of the system (K2), (iii) Derive the overall transfer function of the given Block diagram of a system (K3) and (iv) Derive the overall transfer function of a Signal Flow Graph (SFG) of a system (K3) are considered to measure the effectiveness of active learning methods in attaining the outcome. Active learning methods such as Jigsaw, Think-pair-share and Peer instruction, and traditional lecture-based methods were employed. In addition, ClassComm software with student interactive devices was used to measure the students' learning in the classroom and subsequently the attainment of CLOs. This study compares the effectiveness of active learning methods with the traditional lecture-based instruction method in relation to the attainment of CLOs. The overall analysis results reveal that both instructors and students received the active learning methods very well, and they are very effective in enhancing the attainment of learning outcomes. However, instructors are of the view that the duration of the contact period should be at least two hours. Keywords— active learning, Bloom's taxonomy, concept map, control systems, learning outcomes

Peer-supported Independent Study (psis) - an Effective Model for Enhancing Student Engagement and Optimizing Class Time in Engineering Courses – A Case Study From India
Authors:   Director, IUCEE International Engineering Educator Certification Program (IIEECP) IUCEE Foundation, Kumar Dr. Veena
Published: March 2023

Abstract : Two well-recognized constraints faced by engineering educators in India are sustaining student engagement and completing the prescribed course work within the semester. This paper explores the potential of using a new concept - Peer-supported Independent Study (PSIS) developed by the author to address both these constraints. The concept of PSIS is very different from the traditional independent study as it remains an integral part of the regular course delivery and assessment. Based on a solid theoretical framework of social constructivist theory and peer-instruction theory, PSIS requires the instructor to identify sections of the regular coursework that students can manage by themselves. The instructor then creates tasks from the identified course content that are completed independently by peer groups of 3 to 5 students. The entire PSIS activity is conducted online which helps to save class sessions. The topics identified for PSIS are included in the regular summative assessment. A survey of over 300 instructors across disciplines confirmed that 15% to 18% of the course content regularly taught in classes can be comfortably managed by students themselves and is hence suitable for PSIS. This study was initiated with 106 engineering educators across disciplines from 12 engineering institutions in India though only 63 completed the experiment. A preparatory workshop was conducted to train the instructors for designing and implementing PSIS. Two specially designed instruments were used to collect feedback from 63 instructors and 2865 students (from 63 classes). Results showed increased student engagement at all three - cognitive, behavioral & emotional, levels. 83% instructors reported improvement in class attendance and participation while 58.6% instructors confirmed having saved class time. 92% of participating students found PSIS interesting and rewarding. The study brought out the need for developing more structured guidelines for i) designing PSIS tasks and ii) using the saved time more efficiently.

Abstract : This research article primarily focuses on how speaking competence can be enhanced by Socratic Questioning Approach. There are several methods and approaches formulated and applied at different levels to enhance speaking skills, but critical thinking and questioning attitude is still lacking at undergraduate levels. 32 heterogeneous professional undergraduate students (Creswell, 2018, p.157) have participated in a five months twenty-one days intervention study (Yin,2009 & Stake,1995, p.123) to know the desired outcomes. The pre and post-tests results have considerably and possibly been recorded during the study. CEFR (Common European Framework of References) CAN DO descriptors (Council of Europe, 2018 p.171), are adopted to assess the speaking competence. The pre and post-tests have been assessed based on CAN DO Descriptors. After employing Qualitative Research Methodology (Creswell, 2018) to analyze the data obtained through both succeeding and preceding tests, significant results have possibly been founded and observed that professiona l unde rgradua te student s have considerably enhanced their speaking abilities and competences. CEFR levels of individual performance and variations have scrupulously been observed. This research article ontologically asserts that professional undergraduate engineering students can enhance speaking skills by thinking critically and applying Socratics Questioning Approach (Paul,2006) implicitly and explicitly.

Abstract :Students in higher education, learn many courses in their curriculum, especially in various engineering streams. Not all the courses in the curriculum are accompanied by physical laboratories to have practical exposure. Some of the courses are restricted only to theory content. In this context, simulation-based teaching and learning make such courses more interesting and enhance student learning and interaction in classrooms even in online or offline teaching. For the courses that are supported by simulation software, the facilitator or instructor can apply the simulation-based training techniques, tools, and strategies in designing well-defined learning capabilities. As a part of the study, simulation-based teaching and learning was tested in delivering two courses online. One of them is a third-year course “Antennas and Propagation” wherein the “Antenna Designer” application in Matrix Laboratory (MATLAB) environment was used to ensure the students learn the performance of an antenna, based on various design parameters and the other one is a second-year course “Electronic Circuit Analysis” wherein “Multisim Live online simulator” was used for designing and analyzing the circuits. The participation and engagement of around 65 learners each year were examined by the way they performed the complete design and analysis in the respective courses. The student's performance was assessed based on the clear demonstration of design and analysis they performed. This experiment found that about 80% of students benefitted from the experiment in terms of what they learned and how well they could do analysis, in both courses. This method of simulation-based learning embedded with the instructional design helped the students enhance their exploration skills and hence supported learning new concepts.

El estrés psiquiátrico o síndrome de burnout.- Este concepto de "burning out" es de origen inglés, y en español se traduce como "quemar". A mediados de la década de 1970, el psiquiatra Herbert Freudenberger concibió al síndrome de burnout como una enfermedad mental que experimentan ciertos profesionales que trabajan en todo tipo de organizaciones cuyo trabajo es con humanos. Este síndrome se caracteriza por la debilidad física y psíquica del sujeto que le hace perder todo deseo de realizar óptimamente su trabajo. La obesidad es una enfermedad compleja que consiste en tener abundante grasa corporal. La obesidad trasciende lo estético, es un problema médico que aumenta los problemas de salud, como enfermedades cardíacas, diabetes, presión arterial alta, determinados tipos de cáncer, entre otras. Otro tema de actualidad constante es la salud bucal, siendo la afección más recurrente la caries, que consiste en la destrucción de los tejidos de los dientes causada por la presencia de ácidos producidos por la placa bacteriana depositada en las superficies dentales. Este deterioro de la dentadura está muy influenciado por el estilo de vida, la alimentación, los hábitos de higiene. La herencia también juega un papel importante en la tendencia de los dientes a las caries, entre otros factores. La caries suele ser más común en niños, sin embargo, también puede aparecer en los adultos.

Introduction. Due to a significant number of factors affecting the change in the properties of a dynamic system, excessively conservative processing conditions are chosen to ensure the high quality of the resulting product. This limits the efficiency of the process and leads to an increase in the cost of production. Accordingly, modern approaches are needed that will allow diagnosing the current state of processing and making timely decisions to replace the tool, correct or change the control program. The significance of the ongoing research is to propose a real-time monitoring approach to milling control to identify emerging processing errors, predict potential problems and improve uptime. Subject. The paper discusses the features of the real-time monitoring system during mechanical processing with a single- and double-edge cutting tool, taking into account acoustic wave filtering, minimizing surface roughness. The purpose of the work is to determine the effect of the inclination orientation of the ball-end tool on the surface roughness value using real-time monitoring during milling on CNC process equipment. Methods. The study provides methods of correlation and regression analysis. The calculated data were obtained by means of vibroacoustic diagnostics and measured in the range of values of the variable angle of inclination of the surface for single- and double-edge cutting tool based on the provisions of the theory of oscillations and vibroacoustic diagnostics, cutting theory, digital processing and digital filtering of signals. Results and discussions. Experimental data obtained during machining made it possible to determine that an increase in the angle of inclination of a single-edge cutting tool has practically no effect on the change in the amplitude parameters of roughness. The values of vibroacoustic diagnostics and roughness, when using a double-edge ball-end tool, show a consistent picture with the effects created by the angles of inclination and advance. The obtained solutions to the problems of monitoring and analyzing the roughness parameters can significantly reduce the amount of experimental research and clarify the idea of the practical implementation of the method of acoustic monitoring of the cutting process.

In real production conditions, the technological modes recommended in the scientific literature do not reflect the declared qualities, due to the fact that it does not take into account many factors inherent in the process of finishing grinding, for example, its stochastic nature, changes in its dynamic properties, an increase in mutual vibrations of the tool and the workpiece that appear due to changes in the state of the technological system, for example, an increase in vibrations machine tool due to uneven tool wear, etc. All previously developed models have a limited scope of application, it does not take into account the fact that the appearance of vibrations leads to fluctuations in the depth of grinding, with accidental contact of grains with the material being processed, where one group of grains cuts off the material, the other gets into the trace of scratches left by previous grains, etc. This leads to changes in the values of material removal, surface roughness and other parameters of the technological system, which directly affects the accuracy of processing and the quality of the machined surfaces. The purpose of the work is to develop mathematical models that establish the relationship between the processing modes and the current parameters of the contact zone during the fine grinding of pinholes, taking into account the mutual vibrations of the tool and the workpiece. The research methods are mathematical simulation using the basic provisions of the theory of abrasive-diamond processing. Results and discussion. The interrelations between the cutting modes and the current input parameters of the contact zone when grinding pinholes are established, taking into account the mutual vibrations of the tool and the workpiece, which make it possible to determine the parameters of the system at the output to avoid cost losses, including reducing the number of defective products and time costs. Non-stationary mathematical dependences are constructed that allow determining the cutting modes during the implementation of the grinding cycle, taking into account the magnitude of relative vibrations and the initial phase. It is established that instead of a steady process, harmonic oscillations are observed caused by deviations in the shape of the circle, the intensity of tool wear and other factors, all of the above has a significant impact on the quality of the machined surface. The obtained models are universal for various characteristics of the tool, however, for a more adequate description of the process, mathematical dependencies are needed that take into account the wear of the tool on various binders, which is the task of further research.

Introduction. Existing mixing devices operate at a constant angular velocity of the working body. During this process, there are zones in which there may be no movement of material, which leads to a decrease in the quality of the finished product. When the working body moves with a variable angular rate, the inertia forces, when changing its sign, contribute to the creation of conditions under which the mixture will lose contact with the blade and move to new levels of movement, and this helps to improve the quality and intensity of the mixing process. The purpose of the work is to improve the quality of the processed mixture on horizontal blade (kneading) machine. Methods. Theoretical studies are carried out using the basic provisions of the theory of machines and mechanisms, structural and parametric synthesis, kinematic analysis, mathematical and computer simulation. Results and discussion. In accordance with the proposed method, the synthesis of the cam-rocker mechanism is carried out, which made it possible to select the main dimensions for the cam mechanism: the minimum radius and center distance. For the synthesis of the rocker group, the parameters of the synthesized cam mechanism are used and, using the main parameters for the rocker group (the size of the input link, the angle of the second arm initial position and rocker centre line, equal to 90°). The rocker arm span angle is obtained equal to 103°. As a result of the kinematic calculation, it is found that the dwell time of the working shafts is within 80°. The quality of the mixture can be assessed by the angle of the stagnation zone, which is formed during the movement of granular material. Under static conditions, it is equal to 0.846°, and at variable angular rate — 0.550°. It is theoretically confirmed that inertial forces that change sign four times in one cycle will provide shaking and rebound of the mixed mass from the blades, which, in turn, will significantly improve the quality of the mixture.

Introduction. The main methods of increasing the efficiency of products made from structural steels are considered. A description of diffusion saturation from liquid metal media solutions (DSLMMS) is given. Also, complex diffusion saturation technology (CDS), including DSLMMS and carburization is shown. The purpose of the work is to reveal the effect of steel composition on the process of formation and elemental composition of diffusion-saturated surface layers (coatings) based on chromium, as well as to establish differences and regularities in the processes of formation of diffusion-saturated coatings after DSLMMS and CDS. The methods of investigation. Cylindrical specimens 20 mm in diameter and 30 mm long were subjected to DSLMMS. The specimens were made of carbon and alloyed steels: St3, 20-Cr13, 40-Cr, 40-Cr13, 12-Cr18-Ni10-Ti. At the same time, some of the specimens were previously subjected to vacuum cementation. An eutectic Pb-Bi with the specified content of Cr was used as a transport medium when executing DSLMMS. Metallographic studies were carried out on microsection prepared according to the standard method. Studies to determine the thickness of coatings and its structure were carried out on the Dura Scan Falcon 500 Microhardness Tester. The elemental composition of the coatings was determined by the method of electron microprobe analysis on a Tescan Lyra 3 scanning electron microscope with the Oxford Ultim MAX PCMA system. Results and discussion. As a result of the research, it was revealed that the formation of saturated coatings occurs with DSLMMS and CDS. At the same time, the thickness of the coatings and its elemental composition depend on the steel grade and the technology used. After DSLMMS concentration of Cr varies from 96.9% to 91.1%. At the same time, the maximum concentration of 96.9% is observed on steel St3. After CDS, on the surfaces of all steel samples, the concentration of Cr decreases in comparison with the coatings obtained by the DSLMMS technology on steels: St3 from 96.9% to 66.8%; 40-Cr from 91.1% to 63.18%; 20-Cr13 from 93.18% to 62.54%; 12-Cr18-Ni10-Ti from 92.92% to 64.77%. The total thickness of diffusion-saturated coatings formed on all the alloys studied ranges from 17 to 17.5 µm.
