Abstract
Visual communication has become an important technique for the 21st century’s education. Images and videos are essential tools for better understanding in science and technology subjects. The science and technology subjects can be better understood through a combination of visual communication and application of the theory can be practiced. 40 students from quantitative analysis and instrumentation course were given an assignment using the separation concept. Only two students were unable to perform the task well and these students were also among the students who failed to answer the examination questions involving the application of separation techniques. Correlation tests between assignment and examination scores (involving separation concept questions) showed a positive correlation (r= 61.1). Despite the small number of respondents, the results showed a relatively strong correlation. To address this issue, students were encouraged to share their video among them, so that they can understand the separation techniques excellently.

The rapid changes of the modern world have caused the higher education system to face a lot of challenges
The Z generation students are less focused in the classroom when teaching and learning techniques are incorporated into one-way communication which is in lecture form
There are two obstacles to science communication using appropriate visuals; (1) visual materials are often treated as supplements not as a major part of teaching techniques and (2) there is a lack of recognizing Z generation characteristics as target listeners so that visual materials can be tailored to them (Fadzilah et al, 2010)
Summary
The rapid changes of the modern world have caused the higher education system to face a lot of challenges. The Z generation students are less focused in the classroom when teaching and learning techniques are incorporated into one-way communication which is in lecture form Other approaches such as visual communication need to be emphasized more broadly in order to make the learning and teaching process more effective. Emphasis at university level is usually given to the quality of teaching and learning, as well as research works, studies showed that more attention is focused on research than to the quality of university education (Shirani et al, 2016). This resulted in the graduates being less competitive to meet their job requirements. The best teaching and learning is a combination of teacher-centered and student-centered methods by effectively communicating knowledge while helping students to question their prejudices, and motivating them to learn (Shirani et al, 2016; Elen et al, 2007)
