In the era of digital learning, multimedia-based classroom has been commonly used in higher education including Malaysian higher education institutions. A case study has been performed to evaluate web-based learning using Level 1 to 3 of Kirkpatrick's model in a multi-disciplinary course at Multimedia University, Malaysia. In this study, mixed method research was employed in which triangulation was performed from multiple sources of data collection to give deeper understanding. Students perceived that learning with multimedia was enjoyable. They were also motivated in learning and engaged through the use of web module as multimedia was perceived to motivate them and make learning fun. Students showed significant improvements in their knowledge based on the pre-test and post-test results on learning evaluation. Students were perceived to transfer the learning from web-based learning into the learning outcome. The systematic evaluation can provide the feedback that educators and institution as a whole need to improve the learning environment and programme quality. This study contributes to the research field by adding another perspective in evaluations of web-based learning. It also provides empirical evidence on student perspectives, learning and behaviour in a private university. It demonstrated that the Kirkpatrick's model is useful as an evaluation tool to be used in higher education.

This paper explores the fate and transport of microbial contamination in a cold climate and coarse aquifers. A confirmed norovirus outbreak in a small rural water supply in the late summer of 2004, which is estimated to have infected over 100 people, is used as a case study. A septic system, 80 m upstream of the water intake, is considered to have contaminated drinking water. Water samples tested were negative for coliform and strongly positive for norovirus. Modelling predicts that a 4.8-log10 removal was possible in the 8 m thick vadose zone, while only a 0.7-log10 and 2.7-log10 removal in the aquifer for viruses and Escherichia coli, respectively. The model results support that the 80 m setback distance was inadequate and roughly 900 m aquifer transport distance was needed to achieve 9-log10 viral removal. Sensitivity analysis showed that the most influential parameters on model transport removal rate are grain size diameter and groundwater velocity, temperature and acidity. The results demonstrate a need for systematic evaluation of septic systems in rural areas in lesser studied coarse strata at low temperatures, thereby strengthening data used for regulatory requirements for more confident determination on safe setback distances.

Abstract The aspiration of Malaysian education system as mentioned in the Malaysia Education Blueprint 2013-2025 is to produce students who are highly critical and creative.  Since teaching for higher order thinking was made explicit since 1989, a systematic evaluation of the adequacy and pitfalls of teaching for thinking programs was not done extensively.  If examination result is the yard stick to measure the impact of teaching for thinking, then it can be concluded that 2016 UPSR result painted a dismal picture of failure in teaching for thinking.  Studies showed that there is a positive correlation between language teacher used to communicate in the classroom and the development of thinking dispositions among students.  Using the framework of language of thinking put forward by Costa and Marzano (2001), this study was conducted to explore language of thinking used by teachers during teaching and learning sessions in several primary school classrooms.  This preliminary study attempted to gain in-depth understanding of the phenomenon in the actual setting so that the insight can illustrate a wider picture of the issue.  This exploratory case study employed structured observations to collect data in the classroom of nine primary school teachers.  The data was analysed based on theoretical proposition by Costa and Marzano.  Findings revealed that teachers needed to improve their language of thinking.    Keywords: Thinking skills, language of thinking, teaching for thinking, higher order thinking.   Abstrak Aspirasi pendidikan Malaysia sebagaimana yang disebut dalam Pelan Pembangunan Pendidikan Malaysia 2013-2025 adalah untuk melahirkan pelajar yang berupaya berfikir secara kritis dan kreatif.  Semenjak kemahiran berfikir pada aras tinggi disebut secara eksplisit dalam kurikulum sekolah menengah dan rendah dari tahun 1989 lagi, satu penilaian yang sistematik terhadap kejayaan dan kelemahan pengajaran untuk kemahiran berfikir tidak dibuat secara meluas dan menyeluruh.  Jika keputusan peperiksaan dijadikan kayu ukur untuk mengukur keberkesanan pengajaran untuk berfikir, keputusan peperiksaan UPSR 2016 melukis gambaran kegagalan projek mengajar untuk kemahiran berfikir aras tinggi yang menyedihkan.  Kajian menunjukkan ada perkaitan positif antara Bahasa yang digunakan oleh guru ketika berkomunikasi dalam bilik darjah dengan perkembangan disposisi berfikir dikalangan pelajar.   Disposisi berfikir pula berkait langsung dengan tabiat berfikir dan kemahiran berfikir aras tinggi.  Kajian ini bertujuan untuk meneroka Bahasa berfikir yang digunakan oleh guru dalam proses pengajaran dan pembelajaran di sekolah rendah.  Bahasa berfikir yang diterangkan oleh Costa dan Marzano (2001) digunakan sebagai kerangka teori kajian ini.  Kajian ini cuba untuk meneroka amalan berbahasa guru untuk memahami fenomena ini dalam situasi sebenar supaya hasilnya dapat memberi gambaran luas terhadap isu ini.  Kajian kes eksplorasi ini menggunakan pemerhatian secara berstruktur untuk mengumpul data.  Sembilan orang guru sekolah rendah terlibat dalam kajian ini.  Data telah dianalisis menggunakan toeri Bahasa berfikir Costa dan Marzano.  Dapatan kajian ini menunjukkan guru perlu menambahbaik Bahasa berfikir yang mereka gunakan semasa berkomunikasi dalam bilik darjah supaya aspirasi melahirkan pelajar berkemahiran berfikir aras tinggi dapat dicapai.    Kata Kunci: Kemahiran berfikir, bahasa berfikir, mengajar untuk berfikir, berfikir aras tinggi.
