This research is conducted to identify the scientific conceptual cognition of ecosystem and the corresponding alternative conceptions by lower-secondary school students in Taiwan. Concept mapping, interviewing, and two-tier diagnostic test cannot make explicit reasoning pathways that students may use. Therefore, its purpose is to develop,…

The present study describes the design of a simple teaching module for each student to fabricate a dye-sensitized solar cell (DSSC) that could power a small fan motor. The significance of this laboratory exercise is to stimulate students' motivation by visualizing the light being converted into electricity, which is then switched over to kinetic…

The cultivation of computational thinking and programing education have gained prominence in K-12 education worldwide. Primary school teachers should be proficient in visual programing and using microcontrollers to teach programing courses. To cope with these trends, a learning activity was developed and implemented in Taiwan's primary teacher…

This study developed a computer-simulated science inquiry environment, called the Science Detective Squad, to engage students in investigating an electricity problem that may happen in daily life. The environment combined the simulation of scientific instruments and a virtual environment, including gamified elements, such as points and a story for…

Effective energy education depends on continuing research designed to identify instructional strategies that will proof effective in particular learning contexts. The aim of this study was to help Taiwanese students learn about energy-saving related concepts through idea-centered, collaborative knowledge-building activities carried out in an…

This study aimed to explore the gender differences of participants' learning results, perceptions and gaming behaviors related to an energy quiz game with both single-player and multiplayer game modes simultaneously provided for participants. Seventy-four ninth-grade students played the game in six classes over three weeks. The pretest-posttest on…

This study proposes a home-assembled, low-cost blue light-emitting diode (LED) photometer that uses simple and low-cost hardware and software, costing about US $150. This 425-nm wavelength photometer is controlled by an 89C51 microcontroller chip. Glucose concentration detection experiments involving enzyme coupling reactions were carried out to…

This paper presents a wind power system laboratory activity and an outline for evaluating student performance in this activity. The work described here was to design and implement the laboratory to assist teachers in achieving the teaching objective of this activity. The laboratory teaching activities introduce energy sources, wind energy…
