The main purpose of this study is to develop and validate context-based laboratory activities and low-cost kits for chemistry to improve the practical and laboratory skills of Grade-10 students in a junior public high school. The efficacy of these teaching materials were assessed and quantified by teacher and student respondents using descriptive and quasi-experimental methods. Both laboratory activities and kits were designed to support the use of low-cost chemicals and reagents; and promote the improvisation of equipment and materials. These materials were assessed by 12 teachers and field-tested by 30 Grade 10 students. A standardized multiple-choice pre-test and post-test consisting of 65 items each were used to measure students’ mean gain performances. Prior to using the materials, a pre-test was conducted and have identified students’ least mastered topics, the chemical reaction, Boyle’s and Charles’ Laws respectively. A post-test was administered to measure the mean gain performance after using the materials. Data show that both the teacher and student respondents evaluated the context-based activities and low-cost kits effective and highly acceptable (4.79 on a scale of 5 weighted mean). Mean gain performance in chemistry increased significantly in the experimental group compared to the control group, with Hake’s mean gain scores of 0.63 and 0.25 respectively. The mean scores and levels of mastery of students in the experimental group who used these materials were also significantly higher than those in the control group.

The current study determines the effectiveness of using task-based language instructions in teaching writing at a high school in Thai Nguyen province. The participants consist of 92 grade 10 students from Bing Yen high school, Dinh Hoa district. The study employs a mix method research design (MMR) as the plan for the research. The results of the study reveals that the results of writing performance were reported at a low level (M=3.72). The results also confirmed that the intervention worked well for the experimental group. The mean score of the pre-test (the baseline for both groups) was M=3.72. The intervention focused on TBLT instructions. After first five weeks, the means of post-test1 were M=4.96 and M=3.83 for experimental group and control group respectively. There was a significant difference between the mean of pre-test and post-test1 for the experimental group (M=3.72 compared to M=4.96), while the control group showed a little improvement (M=3.72 compared to M=3.83) the difference was not significant. After another five weeks, the difference in the mean scores of the experimental group were far more than the mean scores of the control group, M=5.56 and M=4.45 respectively. By the end of the fifteenth week of the intervention, the mean of post-test 3 of the experimental group reached M=6.41, the mean for control group was M=5.54. The difference of the mean scores in the pre-test and post-test revealed a significant improvement in both groups. However, the experimental group showed a greater improvement, M=6.41 and M=5.54 respectively. It can infer that the uses of TBLT writing instruction improved writing achievement greatly.

Writing is a complex activity that requires the automation of graphomotor skills. Unfortunately, 10 to 30% of primary school students have difficulty at this level, which impairs the development of writing skills. It therefore seems judicious to intervene in kindergarten to support motor precision as well as visuomotor capacities, considered as prerequisites for writing by many researchers. The purpose of this study was to investigate the effect of motor training on visuomotor integration, motor precision and handwriting performance (speed and readability) in 5-year-old children. According to a quasi-experimental design (pretest, post-test with control group), 34 children participated in an intervention in subgroups, twice a week for 6 weeks. The mean and standard deviation were calculated for each of the tasks performed. Statistical tests (t test) were then carried out. The results show that the children in the experimental group improved their motor precision as well as their graphomotor skills compared to those in the control group. This project provides new insights into the benefits of working on basic skills in preparation for learning to write and will equip teachers on how to guide and support graphomotor skills before entering first grade.
