The purpose of this research was to analyze students’ scientific explanation on the human digestive systems topic using explanation-oriented lesson-design model. This research was conducted with a descriptive research design, a total of 29 eighth grade students from a junior high school in Tasikmalaya were involved in this research. Samples were taken using a convenience sampling technique. The scientific explanation observed was written causal explanation. This research data was collected using test, observation and interview method. The result of this research indicates that the number of students who have scientific explanation ability in intermediate category was 66% (n = 19), basic category was 31% (n = 9), and the advanced category was 3% (n = 1). Therefore, it can be concluded that most of the abilitiy of eighth grade students’ scientific explanation were intermediate category. Overall, students could make the components of scientific explanataion referred to this research. However, the components explaining a phenomenon, most students can only explain a phenomenon using patterns that are commonly observed. In addition, the components explain the patterns in the data and processes that support the occurence of a phenomenon, most students explain the patterns and processes that support the occurence of the phenomenon with spesific, but not detailed. In addition, the components connect data patterns and processes using principles, theories, or disciplinary core ideas, most student connect data patterns and processes using principles by including relevant concepts that are logically, specific, but not detailed.

This research is motivated by the lack of mathematics teaching materials that can make students learn on their own. The teaching material can be created by teachers as they are the ones who possess the knowledge about their students’ characteristics. Further, learning materials are a set of materials (information, tools, or texts) that can aid teachers and students to carry out the learning process. The two-variable linear equation system (SPLDV) is one of the mathematics materials taught to eighth-grade students of junior high school; it contains problems related to daily life. However, it is found that this material is still difficult to master by most students. Therefore, it is necessary to develop the SPLDV teaching materials that can help students learn and solve problems as well as be used as examples by teachers in developing other materials. This research aimed to make problem-based SPLDV teaching materials. The research method refers to the Four-D Model by Thiagarajan, Semmel, and Semmel (1974). It consisted of defining, designing, developing, and disseminating. The results showed that problem-based SPLDV teaching materials could be used in learning activities as the students and the teachers had shown their positive responses after going through expert assessments. This study also suggested that the teachers use this teaching material and adopt teaching materials for other similar materials.

Abstract This paper uses data collected for an MA Thesis on the challenges facing the Directorate of Criminal Investigation Department on management of criminal gang activities, in Nairobi County, Kenya. This study has been necessitated by continued concern among policymakers, security pundits and citizens about the rising criminal gang activities in the country, more pertinently in Nairobi County. Although there are few studies that tried to scratch this area, there has never been a detailed and systematic inquiry and analysis of this problem. The study was guided by several specific objectives; the first objective examined the tactical challenges that the police face in policing gang related activities in Nairobi County, Kenya; assessed the effect of corruption in undermining the war against gang related activities in Nairobi County, Kenya; and finally explored other technological challenges that the police face in policing gang related activities in Nairobi County, Kenya. The study adopted descriptive research design and purposive sampling technique to collect data. Interview schedules and key informants (K.I) guide were the main tools used to collect data using the interview method of data collection. 60 officers of the Special Crime Prevention Unit were the main respondents. Major challenges faced by the DCI officers when dealing with criminal gang activities especially within Nairobi County include; poor relationship between police and the general public as reported by 89.1% of the respondents, increased involvement of women in gang activities which is exacerbated by low ratio of female-male officers for undercover operations and 90.9%. of respondents indicated due to woman innocence will create a greater challenge. Others include; gang related activities with networks and markets especially for stolen vehicles across the borders as a result of corruption along the borders by both police, custom and military officers. Further, 85.5% indicated that cross border gang activities were worsened by lack of harmonized law for the regulation and prevention of these activities that led to enhanced proliferation of weapons as well as drugs to and from the neighboring countries. Major recommendations for policy considerations included; increased recruitment and deployment of female officers to beef up their ratio in undercover operations. Harmonized laws for the neighboring East African community countries and increased cooperation between the security organs of these countries in order to have a coordinated approach of tracking and apprehending criminals who escape to neighboring countries. The study also recommends mandatory training for DCI officers in computer/ technological skills to be able to intercept, interpret and or decode gang related communication and cybercrime related activities.

The aim of this study is to analyze students’ mathematical connection ability on the topic of Phytagoras theorem which reviewed on using CORE learning model at the eighth grade students of SMP Negeri 8 Padangsidimpuan. The research was conducted by applying experimental method (intact group comparison design) with 54 students as the sample and they were taken by using Cluster random sampling technique. Sample was divided into two groups, 27 students as control class (using lecture) and 27 students as experimental class (using CORE).  Based on descriptive analysis, it was found: (a) the average of students’ mathematical connection ability before using lecture learning model was 50.82 (fair category) and after using lecture learning model was 73.66 (enough category) and (b) the average of students’ mathematical connection ability before using CORE learning model was 50.72 (fair category) and after using CORE learning model was 85.25 (good category). Furthermore, based on inferential statistic by using N-Gain, the result showed g= 0.369 (low category) for control class and g=0.706 (high category) for experimental class. It ‘s concluded that using CORE more effective than lecture learning model on the topic of Phytagoras  theorem at the eighth grade students of SMP Negeri 8 Padangsidimpuan.
