    Robust as they are, the existing instructional design prescriptions (Reigeluth, 1983; 1999) which are content-based, expository- and individual-oriented, and generally technology-free are of little use when the task is to design inquiry-based computer-simulated lessons for teaching scientific thinking skills in cooperative learning environments. Thus, the aims of this study were to design a computer-based simulation lesson employing currently available PC and internet software and investigate its effectiveness in various learning situations. The heart of the lesson was the utilitarian Gas Law Simulation program developed by Abraham, Gelder, and Haines (2002) that was incorporated into a hypertext interface display with active links to related notes and worksheets and a superimposed Microsoft Excel table and chart-plotting facility. This package allowed students to review the concepts involved and see relationships between the variables in graphical forms when a selected independent variable was manipulated and all the corresponding values were keyed into the Excel table. A science process skill and HD thinking worksheet was drawn following Lawson’s (1995) prescriptions and the questions and activities were further modified to fit the local syllabus and physics texts. A pilot study was conducted to evaluate and refine the lesson and field testing was conducted using a 3 x 2 factorial design. The first factor was the inquiry-based computer simulation lesson with three modes of cooperative learning, namely, heterogeneous-ability cooperative learning (HACL) group, friendship-based cooperative learning (FCL) group, and traditional group work (TGW) group. The HACL and FCL group were trained following the Kagan (1994) Cooperative Learning Structure while the TGW group which was essentially another friendship-based learning group was not instructed on the Kagan (1994) Cooperative Learning Structure. The second factor was student reasoning ability, namely, empirical-inductive (EI) and hypothetical-deductive (HD) abilities. The sample consisted of 301 Form Four (16-year-old) science students. The results showed that students in the HACL group significantly outperformed their counterparts in the FCL group who, in turn, significantly outperformed their counterparts in the TGW group in scientific thinking and conceptual understanding. The study found that the inquiry-based computer simulation program was effective in enhancing scientific reasoning and conceptual understanding of students of all reasoning abilities but for maximum effectiveness cooperative learning groups should be composed of students of heterogeneous abilities

    The methods of teaching English in Indonesia promote the use of code-switching strategies and have resulted in the widespread practice of pronouncing English words following the structures of the Indonesian language. This study investigated at the effects of the immersive multimedia learning technique with peer support on performance in English in terms of oral production skills in reading and speaking that involved six measures, namely, pausing, phrasing, stress, intonation, rate, and integration without the mediation of the students\u27 first language. It also investigated were the effects on performance by students\u27 achievement. The quasi-experimental 2 X 2 factorial design with pre-test and post-test was employed for the study. The first factor was the strategy of learning, namely the use of immersive multimedia learning with and without peer support, while the second factors comprised achievement in English. 80 first-year university students enrolled in English as a foreign language course were selected for this study and the treatment lasted for eight weeks. Data were analysed using one-way ANOVA. The findings showed that the immersive multimedia learning with peer support group reported significantly better performance in all measures of oral production for reading and speaking. Analyses by achievement showed that the high achievement students in the immersive multimedia learning with peer support group reported significantly better performance in all measures of oral production only for speaking while the low achievement students in the immersive multimedia learning with peer supported group reported significantly better performance in all measures of oral production for reading and speaking. These findings showed that the immersive multimedia technique with peer support reduced the use of code-switching strategies among the students and enabled them to develop oral production skills in English approaching the patterns of native speakers especially among low achievement students

    SECI model is commonly used in explaining the process of interaction and transaction of tacit and explicit knowledge between the experts and novices.The model involves Socialization, Externalization, Combination, and Internalization process derived from organizational practice. As its applicability in the educational context is inconclusive, an investigation was conducted to see if the model could explain the knowledge creation processes for the expository (high hierarchical structure) teaching method in a set of online courses.This paper reports the findings based on a survey conducted on a sample comprised of 371 students enrolled in LMS-supported courses at a university in Malaysia.The instrument has been developed based on the SECI model to measure the interaction and transaction processes for content-based and content-free skills.The data was collected in stages over a semester and analyzed using the latent variable method in Structural Equation Modeling (SEM).The latent variable method requires the extraction of the factors investigated through a measurement model followed by the construction of the structural model employing the extracted factors.For content-free skills, the measurement model reported a good fit for the data, with all factors having significant direct effects hence follows the complete SECI model.However, the structural model analysis for content-based skills reported an acceptable fit for the data with one insignificant hypothesized direct effect, thus produced an incomplete SECI model.The overall findings demonstrates that SECI model is applicable to educational settings and worked well in situations or contexts where students were already proficient

    Objective: This study aimed to evaluate the impact of self-care management on glycemic control in type 2 diabetes patients within primary care facilities in the Kingdom of Bahrain. Materials and methods: It was a cross-sectional study that enrolled a cohort of 400 individuals diagnosed with type 2 diabetes. Data collection included the administration of the Diabetes Mellitus Self-Management Questionnaire (DSMQ). Statistical analysis was conducted using SPSS software version 24.0. The Chi-square test was employed to compare optimal scores in relation to diabetes self-care, while the Kruskal-Wallis test was utilized to assess the impact of patients’ activities, as indicated by DSMQ items, on parameters reflecting HbA1c levels. Additionally, the Spearman rank correlation test was applied to examine the association between knowledge of DSMQ items and HbA1c levels. A statistical significance threshold was set at p < 0.05. Results: The study involved participants with a mean age of 55.6 ± 9.3 years (mean ± standard deviation). Notably, there was a significant negative correlation between DSMQ-16 scores and HbA1c levels (p = 0.026). Similarly, a significant negative correlation was observed between dietary control and HbA1c levels (p = 0.017). Among the various socio-demographic variables examined, only the duration of diabetes exhibited a significant association with the overall self-care score for diabetes (p = 0.045). Conclusions: The study underscores the paramount importance of dietary control in attaining favorable glycemic outcomes in individuals with diabetes. It emphasizes the crucial role of healthcare providers in delivering precise and comprehensive dietary guidanceto all diabetes patients
