Aim: The aim of this study is to use storytelling as a technique to develop entrepreneurial intention in Islamic boarding school graduates. Background: Most of the pesantren graduates in Indonesia do not proceed on to university studies after completing their schooling due to financial problems and so lack the skills to work on jobs that could support their livelihood. Therefore, pesantren wanted to develop a strategy to help its alumni find employment after completing their education. Increasing the entrepreneurial intention of graduates in various sectors is one way in which pesantren expect to support graduates in finding their livelihood. Objective: The objective of this study is to test the effectiveness of storytelling in increasing entrepreneurial intentions in students. Methods: Sixty Islamic boarding school students participated in this study. The Solomon three-group design was used to test the effectiveness of storytelling in increasing the entrepreneurial intentions of students. Participants were divided into three groups: the experimental group, control group 1, and control group 2, each consisting of 20 students. The entrepreneurial-intention scale was used to measure the level of entrepreneurial intention among each group of students. Results First, there was a significant difference between the post-test score of entrepreneurial intention in the experimental group (with treatment) and the post-test score of entrepreneurial intention in control group 1 (without treatment). Second, the post-test score of entrepreneurial intention in the experimental group (with treatment) was not different from the post-test score of entrepreneurial intention in control group 2 (with treatment). Thus, the results were consistent in the sense that the group that received treatment had an increased level of entrepreneurial intention when compared with the group that did not receive any treatment. Conclusion: The results showed that storytelling was effective in increasing the entrepreneurial intention of students. In this study, the treatment of storytelling was integrated with a focus group discussion. Developing treatment with other techniques can have a greater effect on increasing the entrepreneurial intention of students.

Pictures use in an educational setting fits the idiom: old but gold. There have been plenty of studies revealing how good the use of pictures in the classrooms is. Pictures have been long known to have the ability to help motivate, demonstrate, and instruct the students during a learning process. This study is a sort of complement to the phenomenon as it focuses on researching the use of pictures in a classroom. Specifically, it aims at finding out the effectiveness of the use of picture cues in teaching writing.The study belongs to experimental research involving two groups of experiment and control. The eighth-grade students of a private junior high school in Central Java Indonesia are chosen as the subject of the research during 2017/2018 academic year. Employing a sample population technique, the study involves a total number of 56 students who are equally divided into 28 students as the experimental group and 28 students as the control group. The experimental group is taught using picture cues while the control group is taught without picture cues. Pre-test and post-test are used as techniques to collect the data. As for the data analysis technique, it’s done quantitatively applying both descriptive and inferential statistics.The result of the research shows that there is a significant difference in the students’ writing ability between those taught using picture cues and those who are not. This can be seen from the difference in the mean score between them. The result of the pre-test shows that at the beginning, both experimental and control groups have slightly different ability in writing with the mean scores 51.32 and 47.86 respectively. Meanwhile, the result of the post-test indicates an obvious difference between them in which the experimental group gains 65.75 as its mean score and the control group gets 59.14. Furthermore, the application of Independent t-test calculation results in a score of 0.000, which is lower than 0.05. This means that the use of picture cues is effective. Based on these results, it can be concluded that the use of picture cues is effective to teach writing to students.

Mastery Approach

Mathematics is a compulsory subject to all students. It is regarded as a career subject since anything students do after high school revolves around mathematics. Teachers of mathematics always strive to improve students’ performance in mathematics. They always make sure that they complete the syllabus to give students a chance to do better in mathematics. Despite the importance of mathematics, most students in many schools still fail mathematics Examinations. The performance over the years has been persistently very poor. The purpose of this study was to find out which of the strategies of learning mathematics improves students achievement in mathematics; individualization for Mastery approach (IMA) or completing the syllabus (CSA).This entailed the use of the two approaches in the learning of Vectors 11; a form three mathematics topic. This study investigated the relationship between the achievement of students where teachers of mathematics used Individualization for Mastery approach (IMA) and those ones where the teachers worked hard to complete the syllabus. The theoretical framework which guided this study was social constructivism theory. The study adopted a pre-test post-test non-equivalent group design. The target population for this study was all the form three students in 39 secondary schools in Mumias sub-county. Stratified random sampling was used to select schools that took part in the study. The strata were Boys’ schools, Girls’ schools and co-educational schools. From girls’ and co- education schools, the researcher randomly selected three schools from each out of 10 and 26 schools respectively, while from boys’ schools; two schools were selected using saturation sampling giving a total of eight (8) schools that participated in the study. One stream selected randomly from each sampled school took party in the study. Experimental group had a total of 126 students while the Control group had 130 students. The Control group used completing the syllabus approach (CSA) while the Experimental group used Individualization for Mastery (IMA) approach. Each group (CSA and IMA) comprised of four schools selected randomly from the eight schools. The students’ Achievement test was used to collect data. The instrument was developed basing on the objectives and given to the experts in Mathematics Education to validate. To determine the reliability of the instrument, Split half technique was employed since it involves only one testing session and it eliminates chance error. Data was analyzed using both descriptive and inferential statistics. Results indicate that there is a significant difference in achievement between students who used Individualization for Mastery (IMA) approach and those who used completing the syllabus (CSA) strategy in favor of the (IMA) group.

Background: Evaluation of feasibility, safety and effectiveness of percutaneous nephrolithotomy (PCNL) in different age groups.Methods: Between July 1997-October 2012, 233 patients who were 65 years old and older were included in this study. These patients were divided into two age subgroups used in gerontology research. Group 1 was defined as patients 65-74 years old, Group 2 was older than 74 years old. Data from patient records, including demographic characteristics, preoperative evaluation, operative details, and complications were retrospectively analyzed and compared with control group data.Results: The mean age of 233 patients was 69.7±4.6 years. The mean operative times for Group 1, group 2 and the control group were 76.2±47.3mins, 92.9±47.6mins, 77±44mins, respectively and there was no statistically significant difference between groups 1 and 2 and the control group (p>0.05). Twenty-eight of the 233 patients (12%) needed blood transfusion due to perioperative bleeding. The transfusion rates of groups 1 and 2 were 11.3% and 16.7%, respectively. There was no statistically significant difference between the study groups and control group for blood transfusion rates (p>0.05). There was no statistically significant difference in complications between the study and control groups (p>0.05).Conclusions: In geriatric patients, stone-free rates, transfusion rates and other operation parameters are similar to younger populations when experienced surgeons perform PCNL. Despite comorbidities and decreased body reserve, PCNL can be performed without a significant increase in complications in different ages.

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.

This research was intended to investigate the effect of a culture-based approach in improving students’ reading comprehension on spoof text. For that purpose, a true experimental study was applied to the eleventh-grade students of SMAN 1 Soreang. The sample of this study was 88 students from that school. These students were divided equally into the control and experimental group. The experimental group was given the Culture-Based Approach (CBA) as the treatment in comprehending the text.  The students’ scores of pre-test and post-test from both groups were statistically analyzed and compared by the T-test. The findings could be summarized that generally, students from the experimental group gained better achievement than from the control group on their post-test scores. The data analysis also showed that there was a significant difference between the mean score of the pre-test (53.45) and the post-test (58.39.). Furthermore, the result of the t-test (5.707) was relatively higher than the t- table (2.018) for a 0.5 percent level of significance. It indicated that the students’ achievement was significantly improved after the treatment of using a Culture-Based Approach. Thus, it is recommended that a Culture-Based Approach should be considered as an alternative choice for English teachers in teaching spoof text.
