Educational Technology (ET) research encompasses a wide range of areas, including the development of technology tools for learning and teaching, pedagogies for technology enhanced learning, and use of ICT-based materials or tools for learning. The interdisciplinary nature of ET leads to a wide variation in the focus and quality of research articles. Hence there is a need for guidelines for planning, conducting and reporting ET research studies. Such guidelines are also useful to instructors, as they are often well-positioned to carry out applied ET research studies. This article is a mini-tutorial that provides guidelines and templates to conduct ET research studies. The emphasis of this tutorial is on criteria that reviewers use to evaluate research papers and how the criteria can be met. This tutorial is designed to be used with an accompanying set of templates that we have created. The templates offer scaffolds to the researcher during various stages of research, so that reviewers. criteria are effectively addressed.

Engineering is basically the application of the laws of nature for the benefit of the human kind. In the curriculum of majority of engineering branches there are certain abstract concepts. The students find it difficult to understand these concepts. There are many methods which are being followed to make the students under stand concepts. One such method is the use of CAD tools When computers came into class rooms, the need for CAD tools also arose [1]. They help the students to visualize many basic concepts which, they otherwise cannot see in the physical world. In this 21st century, dominated by social networking, the tools required to educate them have also come to be available in free of cost. Such tools are called open source software or FOSS tools. We have proposed a teaching methodology that involves the usage of open source software tools along with traditional teaching which enable the communication engineering students to understand complex concepts pertaining to the subject of Antenna and wave propagation. We carried out an experiment with forty students from fifth semester Electronics and Communication Engineering department. The students used a FOSS tool and gave a test based on designing of various antennas with desired radiation patterns by selecting different parameters before and after using the tool. The scores of the two tests show that there was an increase in the marks obtained by students in the test after using the tool. Thus the use of FOSS tool helped students perform better in the test. This may be because the tool has visualizations which help student understand the abstract concepts such as antenna radiation pattern and wave propagation.

Venkatesh Choppella, V. Kasturi, Manjula Pidaparty
We revive an old but little explored idea about how to think about algorithms and problem solving. Algorithms are discrete dynamical systems, also called iterative systems. Pursuing this point of view pays rich dividends. Important concepts like state space, next-state function, termination, fixed points, invariants, traces etc., can be mapped from dynamical systems to elements of algorithm design. Many of these concepts can be visualised through plots that trace the dynamic behaviour of the algorithm.

This paper describes the current work of designing a website for learning robotics. It supports the post graduate and senior undergraduate students. It is a drive to cater the requirement of laboratory learning. Both theory and virtual experimental resources are made available. The experiments are in the form of simulation. At this stage of web development, the concepts of mechanisms and kinematics have been focussed. The experiment result is shown through web images and text. The website provides ample amount of resource material on the theoretical background of mechanisms and robot kinematics. A step by step fashion has been adopted to impart knowledge in the preliminaries of the subject and gradually guides the client to get a grip over the fundamentals as well as application of kinematics in this domain. Numerical computation along with simulation provides detailed illustration of a concept. The web page integrates MATLAB generated images for clear understanding. The simulation experiments give a real-time feel. This enhances learning, promotes visualization of the problem computation and hence, interpretation of results. Accomplishing this project brings benefit in the form of minimization of cost, time, labor, number of experts. A larger number of students can avail the laboratory and learn on their own pace as the website can be accessed through the internet from any geographical location at any time.

Use of Low Cost Access Devices (LCADs)based on Android platform is on the rise for educational purposes. There is a growing need for open source educational content in order to tap the advantages of this platform.2D/3D animation is preferred to explain complex visalization concepts. Most of the 3D animation content available for desktops has high-poly models. To use these models on LCADs is challenging, because of their low hardware configuration. Methodologies to port 3D content to LCADs (used in gaming industry) are unsuitable for educational visualizations, as they hamper functionality and mesh topology of the objects. It is desirable to remodel 3D content with an objective to use them for LCADs. In this paper we present one such methodology to create low-poly 3D models using open source 3D tool, Blender. The models created using this methodology show reduction in file sizes, mesh-density and loading time on LCADs.

Learning styles theories suggest that people learn differently, an important consideration for adaptive hypermedia learning platforms. Since on such platforms, mode of delivery of course material - visual, verbal or multimedia - plays an important role, this study considers learning styles in the context of adaptive hypermedia with the aim to identify if providing material according to one's learning style enhances performance. While some studies report positive results, others find no correlation between the two. Here, we examine the efficacy of learning styles, especially the visual-verbal dimension of Felder-Silverman model, in a controlled e-learning environment by testing the effectiveness of visual, verbal as well as multimedia modules for history and engineering on 268 engineering undergraduates identified on the basis of visual, verbal and mixed orientations. Contrary to expectations, results indicated no relation between learning styles and performance in modules based on different sensory preferences. However, students did show discipline-based better performance in multimedia and visual modes than in verbal mode. They also preferred multimedia and visual modes over verbal. This corroborates earlier findings - the efficacy of learning styles remains unconfirmed.

The purpose of the paper is to consider the change in the learning approaches of a learner and encourage them to the deep approach of learning. In this study, SOLO taxonomy developed by Biggs and Collis was applied. To determine this, learners used Computer Aided Learning and Printed Text Material where the content made use of proper instructional design which helps to promote deep learning. All students were asked to complete the LPQ before and after the course and the learning approaches were compared after using the three different learning tools - Intelligent Tutoring System (ITS), CD based system and Printed Text Material (PTM) where the contents for all the three tools followed the SOLO taxonomy.

In case of currently evolving choice based credit education system, a student can choose different combination of subjects for completion of the degree. As a consequence, it becomes difficult for the student to identify the correct combination of subjects. Students always look for a knowledge tool which recommends them a package of subjects to be taken. In our research we have proposed a course recommendation tool which strives for satisfying the requirements of the student in the boundary of constraints placed by the university. We have developed ontology for modeling of requirements of students and constraints of the university. We have developed a prototype which communicates with the students to know their area of interest, financial capacity, last degree obtained and past performance to recommend a degree course. It also recommends cross disciplinary subjects based on area of interest, under the constraints of university. Experiments prove the correctness of recommendations.

Professors at VNR VJIET have found engineering students to be less interested in their chemistry courses than in their engineering ones. To motivate these students and enhance their educational experience in chemistry, we implemented changes to our curriculum with the support of a number of technological tools. One of these tools is MediaWiki which facilitated collaboration among instructors on lesson plans and learning outcomes. Other tools such as videos and animations allowed students to visualize the fabrication and working processes at various industries and laboratories. The changes made were successful in fostering student engagement and increased learning.

Educational researchers use observations to collect information about classroom activities as they occur. Currently the most prevalent methods of logging classroom observations are pen-and-paper or video recording. The former is inefficient, especially in large classes while the latter requires expensive infrastructure. In this paper we propose the design framework for the development of a software application for protocol-based multi-observer data logging and analysis called PULSE. Following design-based research we developed the four aspects of this framework. They were iteratively improved over the research cycles based on the feedback of the previous cycles. In this work-in progress paper, we present an ongoing design prototype of the application.
