Development of academic achievements using inquiry-based learning together with educational games

<p>The objectives of this action research were: i) To develop learning achievement in basic science subjects of grade VII students who received an inquiry-based learning (IBL) management system combined with an educational game on the topic of solutions to pass the requirement of 70%; and ii) To study the satisfaction of grade VII students toward the use of IBL together with an educational game. This was a classroom action research study with a target group consisting of 14 grade VII students in the first semester of the 2022 academic year in a public school located in Northeast Thailand. The research tools were eight learning management plans, an IBL questionnaire, an educational game about the solution, a learning achievement test, an interview form, and a satisfaction questionnaire. The statistics used were mean, standard deviation, and percentage. The result showed that the mean was 14.93, and the standard deviation was 1.44, which passed the criteria of 70%, which is in the level of satisfaction. </p&gt

Creativity Development of Secondary School Students Using Four Thinking Activities Blended Inquiry-Based Learning

Creative thinking is more than just thinking; it is a practical ability based on knowledge and experience that allows a person to accomplish things better. The objectives of this research were to design science learning activities and promote the creativity of eighth-grade students who received four thinking activities with inquiry-based learning to pass the 70% requirement and to examine the satisfaction of grade 8 students toward blended learning management of four thinking activities with inquiry-based learning. A total of 31 eighth-grade secondary school students at a public school in Northeast Thailand were selected using purposive sampling in the first semester of 2022. The research tools were seven learning management plans using four thinking activities combined with inquiry-based learning on the topic of the human body, a creativity test, and a satisfaction questionnaire. The statistics used were mean, standard deviation, and percentage. The findings revealed that combining learning management with inquiry-based learning resulted in the development of learning activities. The average score for creativity was 16 (80%), from a total of 20 points. The standard deviation was 1.54, which passed the requirement of 70%. Students were satisfied with the four thinking activities and inquiry-based learning, with a mean value of 4.39, representing a high level of satisfaction

Synthesis of alkaloid-like compounds via the bridging Ritter reaction

Alkaloid-like compounds containing a benzo[c]azepine core structure were successfully prepared in three steps from 5H-dibenzo[a,d]cyclohepten-5-ol via the bridging Ritter reaction. Biological studies of these compounds revealed that some of them are AChE inhibitors and antimalarial agents. © Springer-Verlag 2012
