The electrochemistry designette incorporates design thinking with the objective of reinforcing electrochemistry concepts, introduce prototyping ideas, encourage student class participation, and foster creativity.  The designette uses a mixed methods approach and lies at the interface of design and electrochemistry, allowing students to experience design thinking as a creative tool through the application of electrochemical principles.  The designette permits the students to design and prototype, from an available design prototyping kit, a 6-cell electrochemical device capable of turning on 4 light emitting diodes (LEDs).  The electrochemical device consists of electrode pairs comprised of Cu, Zn, Al, and Sn electrodes, along with rice wine and CuSO<sub>4</sub> solution as electrolytes, connected via staples, wires, and eyelets or combination.  The designette allows for the direct and objective evaluation of students’ performance via three critical parameters:  number of prototypes created, the power harnessed by the voltaic device, and the total number of LEDs powered on by the device.  The effectiveness of the designette as a pedagogical tool for design-based learning (DBL) was evaluated through pre- and post-designette electrochemistry tests.  Results show that the designette improves the student’s ability to recall information, therefore enhancing the learning experience of the students.  Furthermore, we found some evidence between performance in the designette and post-designette creativity, however, no correlations were found between performance in theoretical quizzes, designette performance, or the pre-designette creativity metrics.
