Critical Reflection

My goals for general communication modules have generally remained unchanged throughout my polytechnic and university life. The goals are to maintain an open mind for the module, learn as much as possible, and apply them in my studies as required. I am glad to be able to say that I was able to achieve these goals and learnt new things such as how to produce a technical report and how to critically analyse an article with the reader response assignment. I was also able to make use of what I was taught on the American Psychological Association (APA) style citations in this module for my reference list in another module, and I expect the other skills learnt in this module to be applicable in the near future. Through the various group assignments and the oral presentation, I was able to hone and refine my communication skills. As the class consists of students from varying educational backgrounds and specialisations, it forces me to abstain from using jargon and challenges me to develop creative ways to bring my points across. My individual assignments have also pointed out my weaknesses in grammar and sentence structure, which have become increasingly tougher to crack down on. Nevertheless, I still strive towards perfecting my mastery over the English language by continually using it.

Of all the assignments in the module, I feel that the technical report was the most notable. At first, I thought that being able to decide the problem to be addressed by my team would be a blessing as we would be able to suggest solutions which would be easy to push for adoption. However, it turned out to be a curse as we were unable to find satisfactory solutions to the problems we identified, leading to us running around in circles in an attempt to find a problem and solution that we feel are able to satisfy the criteria of the assignment. The production of the technical report challenged me to think critically about how the solution can be feasibly implemented in Singapore, how to successfully bring my point across to my members, and also how to identify the point being brought forward by my team members who may have difficulty in doing so. The oral presentation associated with the report also showed me the difference that proper and adequate preparations make towards an engaging and effective presentation. While I was fully satisfied with how my presentation went, I could not say the same for the written report. This is due to my difficulty in describing the information in the scholarly journals in the same concise and neutral way it was presented. While it may be difficult now, I do not doubt that this will become easier to do so over time as I get to expose myself to more scholarly journals as references for my future projects.

Overall, this module has helped me to identify my weaknesses and refine my techniques in communication. It has also boosted my confidence in my communication skills and equipped me with better skills to prepare reports and presentations in the future. Naturally, all of these would not be possible with the help of Professor Blackstone and my classmates, to whom I am thankful for providing a conducive and enjoyable learning environment to learn in.

Annotated Summary Final Draft

Mujah, D., Mohamed, S., & Liang, C. (2016). State-of-the-art review of biocementation by microbially induced calcite precipitation (MICP) for soil stabilization. Geomicrobiology, 34. 524-537. Retrieved from www.doi.org/10.1080/01490451.2016.1225866.

This article by Mujah, D., Mohamed, S., and Liang, C., focuses on reviewing the use of biocementation by Microbially Induced Calcite Precipitation (MICP) for soil stabilisation. Evaluation of biocemented soil was made, and it was found to be highly effective for enhancing the engineering, mechanical and physical properties of the soil, which is important to combating settlement, erosion and liquefaction in soils. Utilising MICP for soil stabilisation over chemical grouting methods is not only cheaper, but also "promote sustainability in tandem with future needs". The authors highlighted that while MICP could relieve "present day concerns in soil improvement", there is still a need to address several issues such as treatment homogeneity and up-scaling for MICP to be feasible.

The article serves to provide insightful information on the opportunities and obstacles of soil stabilisation using biocementation by MICP. This information provided in the article is exceptionally useful for my team's research topic on using biocementation by MICP to counter settlement caused by nearby underground works. It also helped to guide our research towards finding solutions to the problems stated in order to make biocementation feasible for soil improvement.

Summary + Reader Response Final Draft

In the web article "I-5 and the Physics of Bridge Collapses", Hartsfield (2013) claimed that the concept behind a functional bridge design is what leads to its failure as well. The article examined the various types of bridges and found that different types of bridges have weaknesses specific to themselves. One such example stated by Hartsfield (2013) is truss bridges, which use geometric shapes as a basis for their strength and stability. As such, Hartsfield (2013) remarked that deformations on the shape will cause the bridge to fail. Suspension bridges fail due to their inability to withstand huge external forces. It is observed by Hartsfield (2013) that "when an external force causes the bridge to vibrate at its resonant frequency, it causes the vibration to grow stronger and stronger". Another example of such phenomenon is cantilever bridges. Hartsfield (2013) alleged that cantilever bridges are designed to be able to withstand the torque that the lever arm takes, yet failures are found to be due to construction oversight and overestimation of the torque it can take. Hartsfield (2013) concluded that understanding a bridge's inherent weaknesses is indispensable to uncovering the reason behind an unforeseen failure. While Hartsfield (2013) did a great job in informing his readers about the various inherent weaknesses in bridge design, he could have mentioned the other factors which can have an impact on said weaknesses.

Despite the flaws in bridge design, it is unlikely that the flaw itself is the only reason leading to the collapse of the bridge. Bridges are designed with the assumption that there will be a certain degree of servicing. Negligence in providing said degree of servicing tends to lead to premature bridge failures. This is supported by Grabianowski (n.d.), who implied that that regular maintenance could avert bridge collapses. While it is important to know the reasons behind the collapse of a bridge, attention should also be brought to the factors which can contribute to a collapse, with a major role being played by maintenance. While it may not be a contributing factor to the collapse of the I-5 bridge, raising awareness on the importance of maintenance can help towards preventing a similar tragedy from happening again. This is especially important as Horgan (2019) observed that there was an increasing trend in bridge collapses due to inadequate maintenance.

It is also likely that the designers and lawmakers are aware of the flaws in bridge design, and that measures are taken to safeguard the flaw. For instance, road barriers could be erected near the crucial supports to reduce the impact of collisions on the crucial supports. Guidelines implemented based on research can also be the deciding factor for when a bridge collapses. For example, it was found that circular column took lesser "blast pressure" than its square or rectangular counterparts (The University of Texas at Austin Civil, Architectural and Environmental Engineering, n.d.). Having the results of such research implemented in guidelines would ensure that future bridges would be more resistant to blast from terrorist attacks.

Although Hartsfield (2013) did well to inform his readers on how the inherent design flaws in bridges can cause their collapses, he failed to mention other factors which can impact the bridge, potentially leading to an unfortunate misunderstanding by his readers. He should include other factors apart from the inherent design flaws so that his readers can get an objective view on the reasons behind bridge collapses.

Letter of Introduction Final Draft

Dear Professor Blackstone

I am writing this letter to introduce myself due to the lack of opportunity to do so in class. My name is Neo Cen Wei, but addressing me as Cen Wei will do. I am a first year civil engineering student attending your communication module, CVE 1281 Effective Communication.

Prior to my university studies, I graduated from Singapore Polytechnic with a diploma in civil engineering with business in 2017. My time in the course has reignited a childhood interest in me for civil engineering, and said interest currently serves as a motivating factor for me throughout my gruelling days of study in university.

What does not serve as a motivating factor for me however is my lack of communication skills daily. I have trouble keeping a conversation going or even starting one, for during times like that my mind just draws a blank. It has always been my weakness since young, and despite having seen improvements over the years, I feel that there is still much room for improvement.

On the other hand, I am quite confident in my ability to articulate and bring points or ideas across to other people. Naturally, it was not all smooth sailing, as I have failed to articulate ideas effectively before. Nevertheless, I am learning from my mistakes and improving myself as I go.

However, I believe that learning and improvement need not be only through mistakes. With this communication module, I hope to hone my communication skills and become a confident communicator in both spoken and written forms. As such, I look forward to the upcoming classes.

Best regards

Cen Wei
