The purpose of the study is generalization of data on the manifestations of hydrogeological earthquake precursors and volcanic activations based on long-term observations in the wells of the eastern part of the Kamchatka Peninsula. The main problem under consideration is the connection between the manifestations of hydrogeological precursors in several wells with the values of the magnitude Mw and epicentral distance of earthquakes to the wells de as well as with the parameters of seismic action in the observation area including specific density of seismic wave energy e and macroseismic intensity of shaking IMSK-64. The study results revealed that hydrogeological precursors in two-four wells had been manifesting for the period from 1 to 9 months before the strongest earthquakes with Mw = 6.6–7.8 at the epicentral distances de = 90–300 km. Such earthquakes were accompanied by the shakings of the intensity of IMSK-64 = 4–6 points. The specific density of seismic energy under such earthquakes was minimum 0.1 J/m3. The hydrogeological precursors were confined to the area for which the ratios of the earthquake epicentral distance de to the maximum linear size of the earthquake source L, km ranged from 1 to 3.7. Using the established relationships between the manifestations of hydrogeological precursors and earthquake parameters, weekly prognostic conclusions were made for expert earthquake prediction councils based on the data of current observations in wells. The well located at the distance of 15 and 20 km from the Koryaksky and Avacha active volcanoes featured the anomalous rise of groundwater pressure before the eruptions in 1991 and 2008– 2009. Therefore, a conclusion can be drawn that observation equipment operating in wells, the study results of hydrogeological precursors of earthquakes and volcanic eruptions as well as their application experience in the work of expert councils can form the scientific and technical basis for the development of geoinformation prediction technology for natural disasters in the Kamchatka Krai.

Socially Shared Regulation

Abstract. Socially shared regulation of learning (SSRL) has been recognized as a new and growing field in the framework of self-regulated learning theory in the past decade. In the present review, we examine the empirical evidence to support such a phenomenon. A total of 17 articles addressing SSRL were identified, 13 of which presented empirical evidence. Through a narrative review it could be concluded that there is enough data to maintain the existence of SSRL in comparison to other social regulation (e.g., co-regulation). It was found that most of the SSRL research has focused on characterizing phenomena through the use of mixed methods through qualitative data, mostly video-recorded observation data. Also, SSRL seems to contribute to students’ performance. Finally, the article discusses the need for the field to move forward, exploring the best conditions to promote SSRL, clarifying whether SSRL is always the optimal form of collaboration, and identifying more aspects of groups’ characteristics.

he purpose of this study was to improve science learning outcomes on the structure and function of plant networks in class VIII students of MTsN 2 Aceh Besar in the 2017/2018 academic year. The learning model used in this study is the Mind Mapping Learning Model. The subjects of this study were students of class VIII MTsN 2 Aceh Besar with a total of 33 students consisting of 13 male students and 20 fe-male students. This research was conducted in the 2017/2018 Academic Year within a period of 3 months, namely from August 2017 to October 2017 in Odd Semester. The research methodology is Classroom Action Research (CAR) consisting of two cycles and each cycle consisting of two meetings. Each cycle consists of planning, implementing, observing and reflecting. The research procedure con-sisted of pre-research, planning cycle one, implementing action cycle one, observing cycle one, reflect-ing cycle one, planning cycle two, implementing action cycle two, observing cycle two and reflecting cycle two. The data collection technique is to collect test scores that are carried out at the end of each lesson in each cycle using a question instrument (written test). Observation data was carried out by look-ing at the activeness of teachers and students during the learning process. The learning outcome data were analyzed by means of percentage statistics, while the observation data were analyzed by means of a Likert scale. The results showed that there was an increase in the completeness of student learning outcomes from 39.39% in the pre-cycle increased to 60.60% in Cycle I and increased to 87.87% in Cy-cle II. Observation of teacher activity during PBM has increased from a total score of 88 good categories in Cycle I, increasing to a total score of 93 good categories in Cycle II. The application of the Mind Mapping learning model can improve science learning outcomes on the structure and function of plant tissue for class VIII students of MTsN 2 Aceh Besar for the 2017/2018 academic year.

he purpose of this study was to increase the activities and results of Indonesian language learning in the exposition text material of class X IS 3 SMAN 4 Banda Aceh. The learning model used in this study is the CTL learning model. The subjects of this study were students of class X IS 3 SMAN 4 Banda Aceh. The number of students is 35 students with 16 male students and 19 female students. This research was conducted in the 2019/2020 school year for a period of 3 months, from August 2019 to October 2019 in the odd semester. The research methodology is Classroom Action Research (PTK) consisting of two cy-cles and each cycle consisting of two meetings. Each cycle consists of planning, implementing, observ-ing and reflecting. The data collection technique is to collect test scores that are carried out at the end of each lesson in each cycle using a question instrument (written test). Observation data was carried out by looking at the activeness of students in the learning process. Data were analyzed by means of percentage statistics. The results showed that there was an increase in student learning activities in both cycles, from good enough to good categories and to very good categories. Completeness of student learning outcomes has increased from 48.57% in the pre cycle increased to 68.57% in cycle I and increased to 88.57% in cycle II. The use of the CTL learning model can increase the activities and results of Indone-sian language learning in the exposition text material of class X IS 3 SMAN 4 Banda Aceh Academic Year 2019/2020
