Online learning has been rapidly developing in the last decade. However, there is very little literature available about the actual adoption of online synchronous assessment approaches and any guidelines for effective assessment design and implementation. This paper aims at designing and evaluating the possibility of applying online synchronous assessments in a formal credit course. Relying on the four dimensions of knowledge taxonomy, this paper describes four different online synchronous assessments for conducting a formal mid‐term exam, including synchronous quiz, synchronous practicum, synchronous essay and synchronous oral assessments. The designs were implemented and evaluated in a synchronous cyber classroom for an online credit course. This study identified the challenges and potential issues while conducting the online synchronous assessments, including (1) the extent of monitoring and cheating; (2) the lack of suitable software tools specifically for supporting online synchronous assessments; and (3) the need for a variety of online synchronous assessment methods for different subject matter. This paper concludes with some possible solutions, such as a short time limit for answering questions and a well analysed need of a software tool, to address all the issues.

Although many researchers have pointed out that educational robots can stimulate learners' learning motivation, the learning motivation will be hardly sustained and rapidly decreased over time if the amusement and interaction merely come from the new technology itself without incorporating instructional strategies. Many researchers have identified that the sustainability of the learning motivation is closely related to the instructional strategies. Accordingly, learners must be well guided by suitable instructional strategies to enhance and sustain their learning motivation. In other words, suitable instructional strategies are required even if introducing educational robots to learners can stimulate learning motivation at the beginning of learning activities. Literature also suggests that systematic instructional strategies can be designed with the use of the Attention, Relevance, Confidence, and Satisfaction (ARCS) model. As the rapid development of robotics, it has become feasible to apply the educational robot for enhancing learning. A robot teaching assistant (RTA) was designed to enhance and sustain learning motivation for the learning of English reading skills. A quasiexperimental design and the Instructional Material Motivational Survey questionnaire were used for data collection and evaluation. The findings showed that the design of the RTA-based learning activities guided by the ARCS model for learning English reading skills can significantly improve learners' learning motivation, learning performance, and continuance intention.
