Design principles for the blend in blended learning: a collective case study

This paper reports on a collective case study of three blended courses taught by different instructors in a higher education institution, with the purpose of identifying the different types of blend and how the blend supports student learning. Based on the instructors’ and students’ interviews, and document analysis of course outlines, two major principles, consolidation and extension, differentiating the design of the three courses, are identified. The consolidation principle emphasises designing different types of activities for students to think again, so that their knowledge can be consolidated. The extension principle emphasises the extension of the space of learning and catering the diverse needs of students. There are also design principles commonly found, with the emphases on student autonomy, interaction and feedback, and the awareness of student diversity. The findings contribute to the design of blended learning, especially on how the face-to-face and online components can be combined.     

Posthumanism as research methodology: inquiry in the Anthropocene

The posthuman turn has radically–and rapidly–shifted what is possible in research methodology. In response, my aim in this conceptual paper is to suggest entry points into posthuman educational research methodology. I outline aspects of posthumanism while recognizing its multiplicity: there are many posthumanisms and each offers different twists, turns, and ways of thinking about methodology. In unfolding the potentials thereof, I locate posthumanism within our current epoch, which some scholars have suggested be renamed the Anthropocene to account for the impact of humanity on the planet. Then, I describe how posthumanism situates, processes, and affirms knowledge in interconnected and material contexts. Next, I consider how non-representational research imagines and animates methodologies that think differently. I conclude by discussing a postdisciplinary future for more-than-critical inquiries. Significantly, this article addresses recent advancements in posthuman research and engages with ongoing theoretical, methodological, and ethical debates.     

Expanding the Disciplinary Expertise of a Middle School Mathematics Classroom: Re-Contextualizing Student Models in Conversations With Visiting Specialists

This article examines how conversations during design reviews in which 8th-grade mathematics students shared population models with visiting specialists expanded the disciplinary expertise of the classroom. Re-contextualizing is a conversational exchange that visiting specialists initiated to invite groups to consider their models in novel contexts. Analysis of 14 design reviews in 2 classrooms showed that re-contextualizing resulted in both the elaboration of ideas students already understood and new contributions to students' understandings of mathematical aspects of population modeling. This article presents case studies of 2 groups that differed in terms of their interest in the curricular task and the level of conceptual integrity of their population models. Despite these differences, the re-contextualizing exchanges that emerged in their design reviews led to new insights for both groups and provided them with opportunities to try on ways of thinking and acting like population biologists.

This article reports the results of the first systematic, though only exploratory, study that assesses the effectiveness of the Philosophy for Children (commonly known as P4C) programme in promoting children's critical thinking in Hong Kong. Forty-two Secondary 1 students volunteered for this study, from whom 28 students were randomly selected and randomly assigned to 2 groups of 14 each: one receiving P4C lessons and the other receiving English lessons. The students who were taught P4C were found to show a greater improvement in the reasoning test performance than those who were not, to be capable of doing philosophy, and to have a positive attitude towards doing philosophy in the classroom. It was also found that P4C played a major role in developing the students' critical thinking, and that 10 crucial factors contributed to the success of the P4C programme.     

Consensus of multi-agent systems with Luenberger observers

This paper studies the consensus problem of the multi-agent systems with parallel Luenberger observers. First, the structure of the cooperative system is established, where the output of the built-in Luenberger observer for each agent is used as its local control input and the cooperative control input combining with the cooperative measurement output is utilized as the input of the observers. Based on the structure of the closed-loop system, the consensus problem is then analyzed. In addition, two methods for designing the controller gains are provided. By virtue of the proposed structure, it is pointed out that the design of the controller gains and the observer parameters can be carried out separately. Finally, by resorting to the gradient flow method, an optimization algorithm is proposed to reduce the influence of the environmental noises. The effectiveness of the obtained results is shown through a numerical example.     

Probing the allocation of attention in implicit (motor) learning

Abstract

We investigated the attention demands associated with implicit and explicit (motor) learning and performance using a probe reaction time paradigm. Two groups of participants learned a golf putting task over eight blocks of 50 trials performed from different distances. One group (errorless learning) began putting from the shortest distance (25 cm) and moved progressively back to the furthest distance (200 cm). A second group (errorful learning) began putting from the furthest distance (200 cm) and moved progressively closer (25 cm). Retention tests were used to assess learning in the two conditions, followed by transfer tests in which participants used either an unusual putter or a very unusual putter. Transfer to the unusual putters had an equivalent effect on the performance of both errorless and errorful learners, but probe reaction times were unaffected in the errorless learners, suggesting that execution of their movements was associated with reduced attention demands. Reducing errors during initial learning trials may encourage an implicit mode of learning and lower the demand for cognitive resources in subsequent performance.     

The dilemma of case‐based teaching and learning in science in Hong Kong: Students need it,want it,but may not value it

The paper reports a study for determining a suitable process for converting traditional surface science courses into case‐based learning ones in two universities in Hong Kong. In this preparative study, a set of baseline data was collected on the current level of students’ conceptual understanding and also students’ perceptions about the traditional courses. The student data (from 38 students) came from examination results, the Study Process Questionnaire, a course‐end survey and a focus group meeting; teachers also kept reflective journals. This set of baseline data revealed factors that both support and inhibit case‐based learning. On the one hand, students demonstrate a motivation to be able to solve practical problems in this field; on the other hand, they show an unwillingness to take up a personal responsibility for learning. This finding strengthens our resolve to take into account students’ expectations and beliefs in the implementation of case‐based teaching and learning.     

Involving parents in paired reading with preschoolers: Results from a randomized controlled trial

A paired reading program was implemented for 195 Hong Kong preschoolers (mean age = 4.7 years) and their parents from families with a wide range of family income. The preschoolers were randomly assigned to experimental or waitlist control groups. The parents in the experimental group received 12 sessions of school-based training on paired reading in 7 weeks. They were required to do paired reading with their children for at least four times in each of these 7 weeks. At the end of the program, the preschoolers in the experimental group had better performance in word recognition and reading fluency than their counterparts in the control group. They were also reported as more competent and motivated in reading by their parents. More importantly, the program had many favorable effects on parents. Parents in the experimental group had higher self-efficacy in helping their children to be better readers and learners. They also reported that they had better relationships with their children. Their changes in relationships and self-efficacy were found to mediate the program impact on some of the child outcomes. However, family income did not moderate the effectiveness of the program. Families with high and low income both benefited from the program alike.
