Development And Validation Of An Astronomy Self-Efficacy Instrument For Understanding And Doing, Rachel Freed, David Mckinnon, Michael Fitzgerald, Christina M. Norris
Development And Validation Of An Astronomy Self-Efficacy Instrument For Understanding And Doing, Rachel Freed, David Mckinnon, Michael Fitzgerald, Christina M. Norris
Research outputs 2022 to 2026
This paper presents a new astronomy self-efficacy instrument, composed of two factors; one relating to learning astronomy content, which we call astronomy personal self-efficacy, and the other relating to the use of astronomical instrumentation, specifically the use of remote robotic telescopes for data collection. The latter is referred to as the astronomy instrumental self-efficacy factor. The instrument has been tested for reliability and construct validity. Reliability testing showed that factor 1 had a Cronbach's α of 0.901 and factor 2 had a Cronbach's α of 0.937. Construct validity was established by computing one-way analyses of variances, with the p value …

Engaging Adolescent Kyrgyzstani Efl Students In Digital Storytelling Projects About Astronomy, Nadezhda Chubko, Julia E. Morris, David H. Mckinnon, Eileen V. Slater, Geoffrey W. Lummis
Research outputs 2014 to 2021
This research is based on the Journey through Space and Time (JTST) educational astronomy project for primary and junior high school science curricula in Australia, which seeks to improve students' astronomy content knowledge through science inquiry. The focus of the current project is on the learning needs of students for whom the language of instruction is a foreign or second language (EFL/ESL). This article reports the results of a pilot case study conducted in Bishkek, Kyrgyzstan in December 2017. The research employed a Type II Case Study design. Data were collected through video and audio recordings of classroom interactions. The …
Ruo2 Ph Sensor With Super-Glue-Inspired Reference Electrode, Wade Lonsdale, Magdalena Wajrak, Kamal Alameh
Ruo2 Ph Sensor With Super-Glue-Inspired Reference Electrode, Wade Lonsdale, Magdalena Wajrak, Kamal Alameh
Research outputs 2014 to 2021
A pH-sensitive RuO2 electrode coated in a commercial cyanoacrylate adhesive typically exhibits very low pH sensitivity, and could be paired with a RuO2 working electrode as a differential type pH sensor. However, such sensors display poor performance in real sample matrices. A pH sensor employing a RuO2 pH-sensitive working electrode and a SiO2-PVB junction-modified RuO2 reference electrode is developed as an alternative high-performance solution. This sensor exhibits a performance similar to that of a commercial glass pH sensor in some common sample matrices, particularly, an excellent pH sensitivity of 55.7 mV/pH, a hysteresis as low as 2.7 mV, and a …
