Abstract

Today's world has graduated engineers in large number with good knowledge of fundamental engineering science but engineers lacks ability to apply that in practice with real time problems. One major reason for this may be that our students are exam oriented. Our emphasis must be on "what is learnt" rather than "what is taught" in class. Faculty should transform themselves from teacher to facilitator. Conventional transform focuses much on engineering science and technical courses without providing sufficient integration between these two. As observed, students study different courses as black box without interconnection between them. This paper presents a learning method that effectively integrates Circuit analysis with Signals and Systems Course. Integrated learning motivates the students to put together the knowledge of the different courses studied previously or in the same semester and apply them in real time problems through integrated tutorials. This learning method facilitates 100% involvement of students in group; help them changing their approach towards learning the course and enabling them to understand the importance and application of what they are learning catering to large class room. Findings shows that there was a significant positive difference in students academic achievement and attitude towards learning the subject through this pedagogical activity.

Abstract

Teaching large classroom is always a very challenging task for educators. This is due to many difficulties imposed on the teaching-learning process. Digital signal processing (DSP) is now pervasive as it is used in everything from digital photo cameras, MP3 players to automobiles. However many students see DSP as abstract mathematics. This is because of the gap between understanding the mathematical formalism of each concept and being able to make sense of them in practice. Getting students actively participate in learning process and motivating them to fill these gaps is a difficult task [3]. To address this difficulty a "recipe" is suggested i.e. "visualizing" the DSP theory with practical applications like speech processing, image processing and so on will help the students in learning better. Sensory stimulation theory of learning says that majority of knowledge held by adults is through seeing (75%) while hearing is the next (13%) and if multi-senses are stimulated; greater learning because of synergy takes place. This theory encouraged us to develop undergraduate level course activity with the applications of audio processing. In this way students are able to see the results of audio processing in MATLAB plots and analyze the results by varying few design parameters. Thus DSP related theoretical concepts will be studied not just as mathematical abstracts but as a useful tools having sense in real world.

Abstract

Electronic Measurements and Instrumentation involves with the measurement of various parameters related to the operation and use of electronic instruments. Measurements play a very important role in all engineering field. As a facilitator we have to strengthen the theoretical concepts by providing a platform for the students to analyze and design various instruments used for measurements. To improve the knowledge of measurements, analyzing and designing is the greatest challenge at the undergraduate level. This paper discusses implementation assignment as an activity introduced in this course to enhance the interest of the students. The purpose of introducing this activity was to correlate the theoretical concepts taught in the class with the hands-on experience. The details of the Implementation Assignment are also presented. The outcomes of the activity facilitates in terms of academic performance along with exploratory learning approach and presentation skills.

Abstract

The real time experience of Signals and Systems has been embedded in the form of mathematical expressions. The learners fi nd diffi culty in applying these mathematical concepts in a real time scenario. This paper presents the details of effective learning technique attempted for the Signals and Systems course at the under graduate engineering program using mind mapping. Mind mapping as a technique tests the student's ability for interactive learning to improve retention and reduce revision time. This paper discusses about the effects of digital/ paper-based mind mapping over conventional teaching method to shift an teaching centric to learning centric. This learning not only focuses on retention of concepts but also caters to the generation of ideas required for solving an engineering problem, which in turn improves the writing skills of the students. Findings showed that there was a signifi cant positive difference in student's academic achievement and attitude towards learning the subject through the paper/digital based mind mapping.
