Abstract

Purpose

This study aims to investigate the perceptions, acceptance, usage and access to social media by students and academics in higher education in informatics programs in Malaysia. A conceptual model based on Connectivism and communities of practice (CoPs) learning theory was developed and were used as a basis of mapping the research questions to the design frameworks and the research outcomes. A significant outcome of this study will be the development of a design framework for implementing social media as supporting tools for student engagement and teaching and learning of informatics programs in higher education institutions (HEIs) in Malaysia.

Design/methodology/approach

A mixed-method research methodology with a significant survey research component was employed for this research. This methodology focused on collecting and analyzing quantitative and qualitative data to better understand the research problems. For this study, a mixed-method sequential transformative research strategy based on a QUAN-Qual model was used in the data collection process. Mixed-method research methodology is considered to be most appropriate for this study, as it allows the researcher to gather multiple forms of data from diverse audiences such as educators, administrators and students.

Findings

The findings show the close matched of the ownership, amount of hours spent online, types of social media technologies (SMTs) used and pattern of usage between informatics and non-informatics students. It also shows that many students and instructors have started to explore and accept the use of SMTs as a tool for engaging with their institution and their peers as well as for teaching and learning purposes. Innovative institutions need to understand the critical success factors and the barriers that restrict the implementation of SMTs within the HEI to take advantage of the opportunities offered by SMTs in higher education.

Research limitations/implications

The surveys and interview participant, in part, are self-selecting, so the data collected cannot be claimed to be representative of the population. However, because of the relatively large number of participants, it can be considered that the findings are indicative. Other limitation includes the depth of data that can be collected using this methodology.

Practical implications

There is wide range of social media usage in educational settings now being reported, but many issues are still unexamined. Limited studies have been focusing on the educators’ readiness, acceptance or refusal in integrating social media into their courses, the perceived effectiveness of the tools and student outcomes for their learning. The central outcome of this research will be the development of a design framework that will be used as a guide for Malaysian HEIs and informatics academics to engage students using SMTs in creating effective learning communities for informatics programs.

Social implications

The framework will have implication for the social interaction and engagement of students with their institution.

Originality/value

Very little work has been reported on student and academic engagement, their perspectives and perceived effectiveness of social media usage in higher education, especially in the Malaysia context. Most of the research focused only on the quantitative research with students from universities in the USA and Australia, with an emphasis mainly on student’s perception and acceptance. There are calls for more research to examine how social media is perceived and accepted by students and academics for teaching and learning, especially in Malaysia.

Abstract

Purpose

The paper aims to investigate effectiveness of the strengthening method, the construction process monitoring, fielding-load tests before and after strengthening, and health monitoring after reinforcement were carried out. The results of concrete strain and deflection show that the flexural strength and stiffness of the strengthened beam are improved.

Design/methodology/approach

This paper describes prestressed steel strand as a way to strengthen a 25-year-old continuous rigid frame bridge. High strength, low relaxation steel strand with high tensile strain and good corrosion resistance were used in this reinforcement. The construction process for strengthening with prestressed steel strand and steel plate was described. Ultimate bearing capacity of the bridge after strengthening was discussed based on finite element model.

Findings

The cumulative upward deflection of the second span the third span was 39.7 mm, which is basically consistent with the theoretical value, and the measured value is smaller than the theoretical value. The deflection value of the second span during data acquisition was −20 mm–10 mm, which does not exceed the maximum deflection value of live load, and the deflection of the bridge is in a safe state during normal use. Thus, this strengthened way with prestressed steel wire rope is feasible and effective.

Originality/value

This paper describes prestressed steel strand as a way to strengthen a 25-year-old continuous rigid frame bridge. To investigate effectiveness of the strengthening method, the construction process monitoring, fielding-load tests before and after strengthening and health monitoring after reinforcement were carried out.
