Engineering Students’ Human Values as Rhizomatic Lines of Sustainability

Environmental Problems: An Analysis of Students' Perceptions Towards Selective Waste Collection

The reduction, reuse, collection and recovery of recyclable materials are sustainable behaviors and people's awareness of them plays an important role in implementing strategies and policies in this field. The quantitative analysis performed on a group of 816 students of Politehnica University of Timisoara, aimed at finding answers to important environmental concerns and observing the students' behaviors of reuse and selective collection of the waste resulted from plastic containers, paper, aluminum, batteries, iron packaging waste, electronic equipment, used cooking oil and printer toner. The research has shown that 'increased amounts of waste' (63.5%) is among the first three concerns Romania has to deal with, besides 'air pollution' (67.9%) and 'deforestation' (63.7%). Moreover, the study highlights the existence of the behavior toward the selective waste collection among students (plastic - 60.3%, paper - 57.8%, and glass - 55.3%). although there are some areas (e.g., selectively collecting used cooking oil or printer toner, their level of knowledge regarding the color code for the recycling bins, etc.) that students still need to be familiarized with through different campaigns, trainings, courses, etc. The results can be used in the development of institutional strategies or of strategic documents targeting environmental protection and sustainable development.

Analysing Students’ Reasons for Keeping Their Webcams on or off during Online Classes

Since, in some higher education institutions, it is not mandatory for students to turn their webcams on during online classes, teachers have complained that their students have adopted this behaviour once the educational activities moved online due to the COVID-19 pandemic. Considering this, the present research aimed to identify the reasons behind students’ choice to hide their faces during online classes and find possible solutions to remedy the situation to enhance the educational process’s sustainability. Thus, this article presents the results obtained by applying an online questionnaire between December 2020 and January 2021 among the students pursuing an academic degree, recording 407 responses. The results highlighted the fact that more than half of the students participating in the study reported that they do not agree to keep their webcams on during online classes, the main reasons being anxiety/fear of being exposed/shame/shyness, desire to ensure privacy of the home/personal space, and chances that other people might walk into the background. The relevance of the research, besides the scarcity of studies on the topic, is also given by the fact that finding and understanding the reasons for this behaviour are, in fact, the first steps in undertaking regulatory interventions on it.
