Blended pedagogy is an important delivery mechanism for open and distance learning. Here, face-to-face meetings in the blended pedagogy model remain as an important platform for teaching and learning. While there are many instructional techniques employed in faceto- face meetings, there is an urgent need to determine how face-to-face interactions in the blended pedagogy can be elevated to boost students' learning. This paper investigates whether productive failure (PF) as an instructional strategy boosts students' understanding of the subject matter in a face-to-face tutorial. PF instructional design advocates the delaying of support for learners during learning. The more they struggle, and even fail, while trying to master new information, the better they are likely to recall and apply that information later. Current research on the impact of PF treatments has shown that effective learning is achieved when learners are presented with a cycle of low structure, high structure and low structure activities. PF instructional design has been used successfully, especially in secondary schools in which learners have regular contact with the instructor. It is unknown whether the use of PF instructional design among adult learners in face-to-face interaction will yield such a positive effect. Can PF instructional design be used in tutorials that cater for adult learners resulting in fruitful learning outcomes? This paper reports an initial study of a quasi-experiment that compares a “productive failure” instructional design with a traditional “lecture and practice” instructional design for a 2-hour tutorial session attended by adult learners. A total of 17 adult learners participated in the study. Learners experienced either a traditional lecture and practice teaching cycle or a PF cycle, where they solved complex problems in small groups without the provision of any support or scaffolds up until a consolidation lecture by their teacher during the last hour of the tutorial. Findings suggest that learners from the PF condition produced a variety of problem models and methods for solving the problems but were unsuccessful in their efforts, be it in groups or individually. They also reported low confidence in their solutions. Despite failing in their group and individual problem-solving efforts, learners from the PF condition performed better than their counterparts from the lecture and practice condition on both knowledge and higherorder application problems based on the post-test. Implications of PF instructional design for adult learners based on these findings are presented.

This paper investigated the effect of productive failure (PF) as an instructional strategy in computer-supported collaborative learning (CSCL) groups using Facebook and a discussion forum. PF is an instructional mode design that advocates the delaying of support for the learners during learning — the more they struggle, and even fail, while trying to master new information, the better they are likely to recall and apply that information later. PF has been used successfully in the classroom. However, it is not known whether the use of a PF instructional modewith adult learners in CSCL groups such as Facebook and discussion forums will produce such a positive effect. A discussion forum is an important platform used to deliver teaching and learning via the Web, while the use of social media, especially Facebook, for teaching and learning has gained prominence lately. This paper reports an initial study that compares a ‘productive failure’ instructional design in CSCL groups through Facebook and a discussion forum. Five Facebook and five discussion forum groups participated in the study. Both groups solved ill-structured complex problems in small groups without the provision of any support or scaffolding from their instructors. The findings suggest that the Facebook groups produced a variety of scope for discussion and deliberation for solving the problems and were more successful in sustaining the discussion compared to the discussion forum groups. Facebook groups also had a higher critical thinking ratio than the discussion forum groups. Based on these findings,the implications of a PF instructional design for adult learners are presented.

Summarizes the policy context, the methodology and the interim findings of a research project intended to produce an indigenous theory of educative leadership in Malaysia. Reports the findings from the first phase of the project. Focuses on the forms of leadership service values in Malaysian school communities as adjudged by exemplary principals and head teachers.

The purpose of this paper is to address the combined effects of thermal radiation and chemical reaction on steady MHD mixed convective heat and mass transfer flow past a vertical surface under the influence of Joule and viscous dissipation.

The governing system of partial differential equations is transformed to dimensionless equations using dimensionless variables. The dimensionless equations are then solved analytically using perturbation technique.

With the help of graphs, the effects of the various important parameters entering into the problem on the dimensionless velocity, dimensionless temperature and dimensionless concentration fields within the boundary layer are discussed. The authors noticed that the velocity increases with an increase in the porosity parameter. An increase in the Prandtl number Pr, decreases the velocity and the temperature field. An increase in the radiation parameter, decreases the velocity and the temperature field. Also the effects of the pertinent parameters on the skin-friction coefficient and rates of heat and mass transfer in terms of the Nusselt and Sherwood numbers are presented numerically in tabular form.
