“…Second, students' performance in our previous study could have been negatively impacted by a lack of sufficient mastery of one or more basic skills [11,12] such as identifying the direction of angular momentum using the right hand rule. Students who are not fluent in those skills may have to devote too many cognitive resources while executing those procedures, leaving insufficient cognitive capacity to process the deeper structure of the problem.…”

An earlier study using sequences of online learning modules found that a significant fraction of undergraduate students were unable to solve similar new problems after learning from an online problem solving tutorial. The current study examines the effectiveness of two methods to improve students' subsequent problem solving performance. First, an "on-ramp" module designed to help students develop proficiency in relevant basic skills was added prior to the tutorial. We found that students' performance on subsequent modules improved significantly over the previous year, and in one of the two sequences we found evidence to support that the improvement was due to the addition of the on-ramp module rather than other irrelevant factors. Second, a new "transfer" module was added after the tutorial and before the final quiz module in which half of the students were given a comparecontrast task and the other half were asked to answer tutorial-style scaffolding questions. On the subsequent quiz module, we did not find significant performance differences between the two conditions, nor did students' performance significantly improve over the previous year. The study demonstrated that mastery-style online homework can serve as an efficient and flexible method for evaluating the effectiveness of new instructional designs.

Oscillations, sound and waves are integral parts of undergraduate physics courses and even high school curricula in many countries. However, they are not always given a lot of attention. It is not uncommon for topics such as kinematics, forces, thermodynamics and electricity to use up most of the curriculum. Yet, understanding of oscillatory and wave phenomena is crucial for understanding resonance and propagation of disturbances in continuous media such as tsunamis and earthquakes. These concepts can then be extended to electromagnetic waves, like 5G networks, microwaves and Bluetooth, and further into quantum mechanics. One of the reasons for the relatively low attention given to oscillations and waves is their perceived difficulty for students. So in this overview, we analyze the research literature on students' reasoning about oscillations, sound and waves to try and find the reasons why the topics results difficult and what can be done about it.

In the Natural Science subject for elementary school, one learns about the waves topic which is derived material from sound energy. Students have been taught that waves have periods and frequencies, including the theoretical application of its application in real life. However, the teacher requires a high effort to explain it because it is quite complicated with a short teaching duration. With the help of information computer technology such as an EDA-based software tool, elementary school students can more quickly understand the sine wave material. This paper reveals on how to teach a sine wave material for children with the following topics, i.e., 1) fundamental concept; 2) the introduction of the instrumental tool; 3) introduction of the used Simulator, periods and frequencies measurement using Oscilloscope instruments; 4) Measurement example; and 5) Practicum. These topics are packaged in a new course outside formal schools. The Circuit Wizard simulator was chosen as a teaching tool; we hope to make abstract contents (ex. sine waves) more exact for children and serve many benefits to improve the teaching quality. This paper focuses on the output frequency measurement using Frequency Generator (FG) & analog Oscilloscope pair under the Circuit Wizard simulation. This course can be taken by 4th – 6th grade (10 – 12 years old children).
