Augmented reality (AR) technology provides context-aware experiences by overlaying digital information onto the real world to enhance learning effectiveness and reduce cognitive load. This study aimed to develop an AR Mobile Learning System (ARMLS) to address the limitations of traditional teaching materials and help elementary-school students learn geometric concepts. The ARMLS was designed based on the fifth-grade mathematics curriculum, covering topics such as definitions, geometric properties, different views of prisms and pyramids, and their relationships. A teaching experiment was conducted to compare students' learning achievement, motivation, and cognitive load when using the ARMLS versus traditional teaching materials. This study adopted a quasi-experimental design, where four fifth-grade classes were selected from an elementary school in northern Taiwan as experimental subjects. A total of 66 students participated in the experiment, divided into two groups: 32 students from two classes as the experimental group (using the ARMLS) and 34 students from the other two classes as the control group (using traditional teaching materials). In the teaching experiment, data were collected through pre-tests, post-tests, and questionnaires. Achievement tests assessed learning effectiveness, while learning motivation and cognitive load were measured with standardized scales. System satisfaction was evaluated using a questionnaire. The Johnson–Neyman method determined the regions of significance in the analysis of covariance. Independent-sample t-tests evaluated differences in learning motivation and cognitive load between the groups, and descriptive statistics summarized system satisfaction responses. The results indicated that (1) the ARMLS enhanced the learning achievement among low- and moderate-achieving students, (2) there was no significant difference in learning motivation between the two groups, (3) the ARMLS helped reduce students' cognitive load, and (4) most students expressed satisfaction with the ARMLS according to the questionnaire results. The ARMLS enhances engagement and deepens understanding by making abstract geometry topics more accessible. It effectively overcomes the limitations of traditional teaching materials, providing elementary students with an interactive, hands-on approach to learning geometric concepts.

Beginning learners of English frequently use flashcards as a tool for learning vocabulary. However, because of the consciousness difference between the picture-readers and picture-drawers on vocabularies, errors may be involved in the learners' comprehension of the vocabulary terms on the flashcards. This article develops and evaluates an English vocabulary learning strategy for tablet devices on which learners' viewing and drawing corresponding to vocabularies on the mobile devices. Fifty-two elementary school students were recruited and divided into two groups: The first group read the printed flashcards from electronic files, the second group read the flashcards drawn by students themselves. The results indicated that the drawing learning strategy was beneficial for increasing both their learning motivation and memory retention. The learners could create their own learning content by drawing pictures in such a manner that the pictures were highly relevant to the meaning of the target word, thus transforming their learning pattern from passive to active.

The goal of this study is to develop a virtual farm for educational applications. Users can play the role of a farmer by planting vegetables and raising poultry on the virtual farm to observe their growth through online learning activities. The virtual farm possesses educational and entertaining functions, and it is designed by simulating the real situations of being a farmer to enhance users' interest and motivation in learning agricultural knowledge. It also provides an alternative way for city people to experience interesting farm life. The virtual farm is highly interactive with 3D visual effects and the attractive features of distance learning, and thus it can be used as an assistant tool in elementary science education. A teaching experiment was conducted and the results showed that the virtual farm could enhance students' learning effectiveness and motivation. (Contains 8 figures and 2 tables.)
