Videos and other audio-visual aids are referred to as postsecondary instruction. They help to support students’ learning and build on their knowledge through step-by-step explanations. Problem-solving videos (PSVs) are Internet-based resources that are used to assist learners in revising their knowledge of general chemistry. They can be utilized to replace out-of-lecture review meetings and other activities that prepare students for their chemistry exams.
One of the most crucial benefits that this method can bring is that learners can brush on their knowledge at the time that is convenient for them. In addition, they can watch PSVs repeatedly to dwell upon the assignments or tasks that are more difficult for them. Therefore, such learning experience becomes more valuable since students receive an opportunity to tailor it based on their needs.
PSVs are helpful to boost students’ understanding of algorithms during the second semester. The curriculum of general chemistry classes becomes more intense and requires multiple postsecondary instructions. Since it includes mathematical equilibrium problems, many students become confused with the growing body of the theoretical construct. Therefore, PSVs assist in avoiding the confusion since students can make allusions to their previous knowledge and by solidifying their comprehension of multiple themes. It is assumed that watching PVSs can be equated with having a private tutor.
Many students re-watch videos to further their knowledge before the examination and gain control over their understanding since such instructional tools enable the provision of systematic explanations. Apart from that, educators benefit from PSVs as well since they can allocate more time to other activities during classroom sessions. For instance, they can have more time for teamwork and active learning. The effectiveness of PVSs lies in the fact that they activate two channels of perception. In particular, students use audio and visual receptors to comprehend the information. In addition, they can analyze the information from verbal and pictorial patterns. It has been evidenced that the use of two channels simultaneously results in better memorization compared to the use of only one channel.
