The main objective of this chapter is to present the empirical results of an experimental study carried out with 9th grade students for teaching electrical circuits. The experimental research took place during April and May 2013. In the study, the authors compared two instructional approaches (4C/ID versus conventional). Thus, the results obtained by two groups (experimental and control) on the variables ‘performance', ‘perceived mental effort', and ‘instructional efficiency' were compared. The results revealed that, globally, the experimental group obtained better performances, with less perceived mental effort (i.e., better instructional efficiency). These results were discussed in 4C/ID-model theoretical framework.

Pictures use in an educational setting fits the idiom: old but gold. There have been plenty of studies revealing how good the use of pictures in the classrooms is. Pictures have been long known to have the ability to help motivate, demonstrate, and instruct the students during a learning process. This study is a sort of complement to the phenomenon as it focuses on researching the use of pictures in a classroom. Specifically, it aims at finding out the effectiveness of the use of picture cues in teaching writing.The study belongs to experimental research involving two groups of experiment and control. The eighth-grade students of a private junior high school in Central Java Indonesia are chosen as the subject of the research during 2017/2018 academic year. Employing a sample population technique, the study involves a total number of 56 students who are equally divided into 28 students as the experimental group and 28 students as the control group. The experimental group is taught using picture cues while the control group is taught without picture cues. Pre-test and post-test are used as techniques to collect the data. As for the data analysis technique, it’s done quantitatively applying both descriptive and inferential statistics.The result of the research shows that there is a significant difference in the students’ writing ability between those taught using picture cues and those who are not. This can be seen from the difference in the mean score between them. The result of the pre-test shows that at the beginning, both experimental and control groups have slightly different ability in writing with the mean scores 51.32 and 47.86 respectively. Meanwhile, the result of the post-test indicates an obvious difference between them in which the experimental group gains 65.75 as its mean score and the control group gets 59.14. Furthermore, the application of Independent t-test calculation results in a score of 0.000, which is lower than 0.05. This means that the use of picture cues is effective. Based on these results, it can be concluded that the use of picture cues is effective to teach writing to students.

Experimental study of the influence of crystalline silicium upon the damaged physis of the proximal femoral growth zone was performed in 24 Chinchilla rabbits. Defect of growth zone was created by drilling (2.6 mm in diameter). In first experimental group a metallic screw was inserted into the created defect. In the second group silicium monocrystal 5x5x0.5 mm was placed into the defect next to the metallic screw. In control animals only the defect was created. In animal from 1st and control groups roentgenological picture showed the development of deformity in the operated extremity. No deformity was detected in animals from 2nd experimental group. Positive effect of crystalline silicium upon the damaged growth zone function was noted. Further study of this phenomenon may be perspective for the elaboration of new implantation materials with a view to stimulate regeneration of affected physis, preservation of its function, bones deformity prevention and correction.

Online explanation videos on platforms like YouTube are popular among students and serve as an important resource for both distance learning and regular science education. Despite their immense potential, some of the explainer videos for physics include problematic explanation approaches, possibly fostering misconceptions. However, some of them manage to achieve good ratings on YouTube. A possible reason could be that explainer videos with misconceptions foster an “illusion of understanding”—the mistaken belief that a topic has been understood. In particular, misconceptions close to everyday experiences might elicit greater interest and appear more convincing than scientifically correct explanations. This experimental study was conducted to research this effect. Physics learners (N = 149), with a low prior knowledge enrolled in introductory university courses on primary education, were randomly assigned to experimental and control groups. While the experimental group watched a video introducing the concept of force relying on misconceptions, the control group watched the scientifically correct video. Both videos were comparable in terms of comprehensibility and duration. In the posttest, the experimental group believed that the video was scientifically correct, well-explained, and that they do not require further instruction to understand the concept—indicators of an illusion of understanding. The video including misconceptions was perceived as better understandable than the scientifically correct video (d = 0.62*). The experimental group was significantly more convinced by the misconception after watching the video than the control group (d = 1.86**). They learnt more erroneous knowledge about the misconception than the control group about the scientifically correct concept (Cohen’s q = 0.37*). We argue that this might become problematic (a) in physics instruction because students who have watched a misleading video might regard further teaching in school as irrelevant, and (b) learners might tend to rate videos including misconceptions better on an online platform like YouTube.
