By combining the means of the center manifold theorem and Planar branching theory, this paper studies the sufficient conditions for general three-dimensional systems to branch out into spatial periodic solutions under mixed perturbations, and obtains two theorems for judging the periodic solutions of general three-dimensional systems branching out from closed orbits, which generalize the results of existing planar systems.

This exploratory study attempted to examine the relationship between the level of performance of Bachelor of Science in Computer Science (BSCS) students in their on-the-job (OJT) course and their academic performance in selected programming courses. It also aimed to identify key predictors of OJT performance. The data used in the study included academic and background records of 185 senior BSCS students from the University of the EAST (UE) who were enrolled in their OJT training course during the summers of AY 2014-2018. Data was analyzed in several levels using descriptive and correlational methods using SPSS software. Results indicate a significant and positive but weak relationship between the students' academic performance and their OJT performance. Scholarship status was found to be a more important predictor of OJT performance than academic performance in programming courses. The study, although preliminary, provides valuable insights in the quest to continuously improve the curriculum of the BSCS program in order to provide graduates with the core competencies expected of them in the computing industry.

In this paper, we analyzed the growth and development of international education programs in secondary schools in China, within which MSL (Mathematics, Science and Technology) education in a bilingual environment (mainly English and Mandarin) is an essential section. One of the barriers for their further expansion is the unbalanced regional distribution and the resulting shortage in qualified educators. Blended learning is adopted in teachers' professional development to optimize the allocation of resources with the help of online modules designed based on subjects and stages, followed by regular offline workshops.

This research investigates the impact of experiential learning methods in teaching system modelling in a higher education ICT classroom. We hypothesize that the integration of visualization and gamification by incorporating 3d printed objects and a virtual video 3600 case scenario can improve learning motivation, engagement and enhance learning outcomes. The data was gathered through a usability test using a Likert scale from students (n=24) of two conditions (control group n=12 and experimental group n=12), using a design-based research methodology. Significant results were found for 11 of the 14 usability questions asked of the participants during the study. Preliminary results show that the experiential learning activities promoted engagement and motivation and had a positive effect on learning. Using 3d printed objects provides an added layer of facilitated interaction for individuals and between learners on the usability measures of manipulability, memorability, navigability and communication. However, measures of creativity, visibility and efficiency were not significant due to the delivery and novelty of the approach. Based on the positive results of the usability test, further work is required to refine the intervention. This includes unpacking the effects of visualization and gamification on motivation, engagement and learning in system modelling.
