This study aims to determine the influence of learning models (Contextual Teaching and Learning and Quantum Learning) and the ability to think creatively about the learning outcomes of science education in junior high school students in SMPN 226 Jakarta. This research uses treatment design by level with sample number of 48 students at State Junior Secondary School (SMPN) 226 Jakarta. The data analysis was done by Analysis of Variance (ANAVA) two lane. The results showed that (1) Contextual Teaching and Learning model (CTL) was more effective in improving learning outcomes of IPA SMP Inclusion than Quantum Learning model (QL); (2) there was interaction effect between learning model and student's creative thinking ability toward science learning outcomes 3) for junior high school students in inclusion schools with high creative thinking skills more appropriately using Contextual Teaching and Learning models (CTL), (4) and for students with low creative thinking skills more appropriately using Quantum Learning models (QL).

This study aims to determine the effect of open ended learning approaches and thinking patterns on student learning outcomes in Mathematics. The research method used in this study is an experimental method involving two variables, namely the independent variable (treatment variable) and divergent thinking patterns as the independent variable (moderator variable) using a 3 x 2 factorial design. Further measured variables include two main variables, namely the independent variable and the dependent variable. The results show that: 1) there is a significant influence between the open-ended learning approach and the direct learning approach to student learning outcomes in Mathematics. 2) There is a significant influence of thinking patterns on student learning outcomes in Mathematics. The results indicate that learning outcomes of students in Mathematics who have divergent thinking patterns are higher than the learning outcomes of students who have convergent thinking patterns; 3) There is an interaction effect between the learning approach and thinking patterns on student learning outcomes in Mathematics; 4) Learning outcomes of students in Mathematics who have convergent thinking patterns taught with the open-ended learning approach are significantly greater than learning outcomes of students in Mathematics of students who have convergent thinking patterns and are taught with the direct learning approach.

Politeness is an important aspect of human interaction. In daily communication, misunderstandings often occur due to inappropriate use of language. This aspect must be taught in teaching and learning so that students are trained to apply it in daily communication. In fact, the teaching and learning process is often more focused on mastering vocabulary and grammar to support language skills rather than politeness. This study aims to obtain a picture of the level of politeness of students communicating in the context of German language and culture. How do they use the strategy to keep the face of their speech partner? When commenting, for example, do they deliver using direct speech acts or are they more likely to choose indirect forms. The results of the study illustrate that the knowledge of students' politeness in speaking needs to be improved. Although they have learned German, including its communication culture, students still use Indonesian patterns in communication. In asking their friends to do an action or by giving some comment, for example they are more likely to use indirect forms, lthough according to the context of communication actually considered polite if delivered with a direct pattern. That happened because they lacked in training how to use language in the context of German culture. For this reason, it is necessary to adjust the curriculum of the German department to accommodate politeness training process in speaking skills. Linguistics skills that are taught for certain communication contests such as asking for help, borrowing something, inviting, answering questions, making comments, rejecting, conveying information, giving opinions etc.must be complemented with an exercise in how that context authentically used in German culture.

This study aims to produce storyboard video guidelines in the Taiwanese Bread processing practicum and determine the feasibility of storyboard video guidelines in the Taiwanese Bread processing practicum. The study method used Research and Development (RnD) by Dick and Carey's model development. The study sites included the processing laboratory, and the pastry and bakery laboratory. Data collection techniques involved interviews, documentation, and questionnaires. Data analysis techniques used documentation, qualitative, and quantitative data analysis. The procedures of designing storyboard video guidelines in Taiwanese Bread processing practicum were conducted by preparing material, making a script, and preparing a storyboard. To assess the feasibility of storyboard video guidelines, content validation was assessed by a material expert, media expert, and learning expert. The study result revealed that the storyboard video guidelines were feasible to be developed in the Taiwanese Bread processing practicum. The average level of feasibility obtained was 79.57% for the feasible category of material experts' judgment, 77.54% for the feasible category of media experts' judgment, and 86.12% for the very feasible category of learning experts' judgment. It concluded that the storyboard video has a valid, practical, and potential effect in the Taiwanese Bread processing practicum.

This research is aimed at producing a character education based Social Studies comic media (comic media), for effective teaching and learning for students in primary schools. Its ISBN number is 978-602-8768-35-1 and its intellectual property rights "HKI" number and date are EC00201814589, 4 June 2018. In addition, such media will able to improve their reading interests, to eventually improve their Social Studies results. The method of Research and Development was drawn from Dick et al. (2009). Fifth graders in the sub-district area of Jatisari, Indonesia were surveyed. The t-test was calculated to be t-count (11.67) > t-table (2.05). That means a significant improvement in Social Studies results, by using comic media, to teach Social Studies. In other words, a combination of text and visual aid (comic book) tend to support better learning than a mere text.

The results of the interviews with teachers obtained very good results. In conclusion, the module of the response to intervention model can be said to be good, but still needs to be improved in accordance with expert advice, as well as teachers as users.

This study aims to obtain empirical data, analyse, assess and recommend key and important things about input in the form of contributions from university leaders to obtaining university resources. These include: organisational structure, planning, SOP, facilities, human resources, and a budget that directly or indirectly contributes to the realisation of a learning organisation. This research uses a qualitative approach. Qualitative research emphasises in-depth data collection from several individuals or in a restricted environment (Cozby & Bates, 2012) where findings are not obtained through statistical procedures or other forms of calculation (Corbin & Strauss, 2008). This study uses the CIPP evaluation model, which is fully carried out with a qualitative approach. In certain aspects, a qualitative approach cannot always portray all phenomena of a leadership style in realising the learning organisation of UBP Karawang. The results showed that the leadership, in obtaining university resources, included organisational structure, planning, SOP, facilities, human resources, and a very large budget. All resources are mostly allocated for learning activities so that they directly or indirectly contribute to the realisation of learning organisations.

The research is to determined the effect of instructional strategies and metacognition on mathematics learning outcomes with initial mathematics knowledge as covariat variable. This research conducted at state vocational high school 7 Bekasi during March to May 2018 an used a quasi experimental method with treatment by level 2×2. A sample of 64 students was randomly chosen. Analysis Covariat (ANCOVA) and Tukey tes applied to analyzed the data. The result show that: (1) Mathematics learning outcomes between groups of students were given an inquiry learning strategy was higher than the group of students who were given conventional strategy controlled by initial mathematics knowledge; (2) There is an interaction effect between learning strategies and metacognition on mathematics learning outcomes with initial mathematics knowledge; (3) For a group of students who have a tendency to metacognition high, mathematics learning outcomes between groups of students taught inquiry learning strategies higher than those students who are taught by an expository strategy controlled by initial mathematics knowledge; (4) For a group of students have a tendency metacognition low, the result of studying mathematics between groups of students taught using inquiry learning strategy is not different with group of students taught by an expository learning strategy controlled by initial mathematics knowledge.
