Learning musical instruments has been rapidly popular during the past decades. However, it is faced with COVID-19 pandemic restrictions and lockdowns, which limit face-to-face music lectures. This research aims to design and develop an online instructional system named Nuance for learning musical instruments. The system performance is tested and analyzed to study the impact of the proposed system on cognitive and practical learning skills for a Persian musical instrument named Setar. This study uses a "quasi-experimental research" method for a population of 900 Setar elementary students in Sanandaj city during the 2021-2022 academic year. A convenience sampling method is used to form two homogenous groups, including control and experimental, each with 15 learners. The experimental group uses the Nuance system, while the control group receives online videos. The Shapiro-Wilk test is used to test the data normality, while one-way ANOVA and Tukey post hoc tests are used to analyze data and study the performance of the proposed system. The results show a significant difference between both the groups and support that the proposed system has a better performance for cognitive and practical music learning skills than the standard online system (P <0.05).

This study is investigated the effectiveness of science education with STEM approach, in a combined (face-to-face and virtual) method, on problem solving skill of the students of the middle school in the topic of energy. This research is a semi-experimental and pre-test-post-test type with the control group. The statistical population is all the 7th-grade male students from middle school in Tabadakan region, Mashhad 2021-2022. From this statistical population, 70 students were selected by the convenience sampling who were in two classes. One of the classes was randomly selected as the experimental group and the other as the control group. The control group received training through the traditional approach, whereas the experimental group underwent training using the STEM method. The research tool was Hepner and Patterson's (1988) standard problem solving skill questionnaire. In order to develop lesson plan with STEM approach, the proposed standard framework (STE(A)M IN INTEGRATED LEARNING SCENARIO) was used. Data from questionnaires was analyzed using SPSS, with statistical indicators calculated and normality. Also, hypotheses investigated using Kolmogorov-Smirnov tests and covariance analysis. The significant values obtained for problem-solving skill (0.033) and its subscales, including Confidence (0.022), Approach-Avoidance style (0.046) and Personal Control (0.025), indicated that the STEM approach was helpful in improving learners' learning and strengthening their problem-solving skill. Also, this study showed that students generally have difficulty learning scientific concepts and problem solving skills, but hybrid approaches such as STEM can improve educational processes and learner performance in developing countries such as Iran. Therefore, the role of STEM approach in education becomes highlighted.

Open Soft Software brings about a powerful learning environment, and it transforms the learning and teaching process in which students deal with knowledge in an active and self-directed way. However, over-reliance on conventional methods, lack of awareness, skills, knowledge, among others, are factors militating against the adoption of OSS for learning. This study examines the self-efficacy in the use of open-source software for instruction among undergraduate pre-service teachers in Lagos State. The population for this study were pre-service teachers in all universities in Lagos State. Purposive sampling technique was used to select the universities from where the student samples were drawn based on public universities that are on campus. The instrument for data collection was an adapted questionnaire. Descriptive and Inferential statistics were used to answer the research question and test the stated hypothesis with the aid of stastistical product and service solution (SPSS) version 20.0 at 0.05 level of significant . The findings indicated that undergraduates have low self-efficacy in the use of open-source software for instruction. Also, significant difference exists between male and female pre-service teachers’ self-efficacy on OSS for instruction in Lagos State. This study concluded that most pre-service teachers in Lagos State did not have the skills necessary to use OSS for learning. Therefore, the study recommended that government should organise training for pre-service teachers on the use of OSS for learning.
