Small private online courses (SPOCs) have influenced teaching and learning in China's higher education. Learning management systems (LMSs) are important components in SPOCs. They can collect various data related to student behavior and support pedagogical interventions. This research used feature engineering and nearest neighbor smoothing models to predict the performance of students. Five learning behavior features were selected based on Spearman's rank correlation coefficients with students' final grades. Through testing with data from the fall semester of 2020, the model attained the highest ROC-AUC value of 0.9390. Based on these models, the researchers conducted an engagement intervention that displayed learning behavior dashboards to students in the fall of 2021. During the intervention, the course platform updated the dashboards and notified students weekly. This intervention was further investigated through a randomized controlled trial. The experimental results suggested that the intervention could improve students' learning behavior in terms of total study time, tutorial reading, and video viewing. In addition, this study used a modified dynamic key-value memory network model to depict a student's knowledge state and to calculate the probability of solving an exercise by mining numerous exercise records. Based on the predicted probability, instructors could recommend personalized exercises for each student. In the fall of 2021, the researchers also conducted a randomized controlled trial on this intervention, demonstrating that this personalized exercise recommendation could increase students' concept mastery. Experiments revealed that the proposed models and interventions had a positive effect on students' learning of course content.

Background: Training parents to implement language and communication intervention strategies is an effective approach to promote language development for children with language delay. Aims: This study introduces an online parent training program conducted in Hubei province, China, which was designed to help parents of language‐delayed children with a diagnosis of autism spectrum disorder (ASD), developmental language disorder (DLD) or global developmental delay (GDD) apply language intervention strategies into daily interactions and promote their children's language development at home. Methods & Procedures: The Bethel Hearing and Speaking Training Center Family Training for Early Communication & Language Development (Bethel Family Training Program, BFT) (Bethel HSTC, 2020) was designed to improve the language and communication skills for children with language delay in a naturalistic way. The caregivers (including parents, grandparents and other main caregivers) participated in an 8‐h online program, including lectures on milestones in child language development, common misunderstandings of child language development, and three basic family language intervention strategies ('Looking together, playing together, and talking together') incorporating active learning through video analysis and discussion. Tongji Hospital in Hubei then continued with 3 months of online home intervention monitoring to all the caregivers via weekly online Q&As led by BFT certified speech therapists' team. The Gesell Developmental Schedules (GDS) was carried out before the online parent training program and after the 3‐month online home intervention monitoring. Outcomes & Results: 146 families whose children aged 12–68 months with language delay participated in the online training program. The results of the GDS assessments conducted before and after the program showed that not only did the developmental quotient (DQ) of language improve, but so did the DQ of social behaviour and adaptive behaviour (p < 0.001). There is no between‐group difference in the application of three strategies between the ASD group and the DLD or GDD group (p > 0.05). Furthermore, both caregivers' ability to apply 'looking together, playing together, talking together' strategies and the effective interaction time played important roles in improving the child's language abilities. Conclusion & Implications: The online parent training focusing on improving daily interaction with children through speech–language stimulation strategies promoted the development of language skills. It is an economic and practical approach for children with language delay who have limited access to local language intervention programs. WHAT THIS PAPER ADDS: What is already known on the subject: Parent‐implemented language intervention is an effective approach at improving children's language development. Telepractice is an appropriate model of service delivery for audiologists and speech–language therapists and may be the primary mode of service delivery or may supplement in‐person services. What this paper adds to the existing knowledge: This paper explores the effectiveness of an online parent training program and provides new evidence that online training on language support strategies (looking together, playing together, talking together) followed by home intervention monitoring works for Mandarin‐speaking children and it is equally effective for children with ASD and non‐ASD diagnosis. What are the potential or actual clinical implications of this work?: Developmental behavioural paediatricians and speech–language therapists in countries and areas that lack sufficient training resource for every child will have the option to deliver parent training and home intervention monitoring online, which will save time and cost considerably while offering convenience.
