ABTRACTThe development of the 21st century skills requires educators to prepare students for global economic competition by having special skills, one of which is problem solving. Achievement of the 21st skills century is done by improving the teaching profession, one of which is through lesson study for learning community. The purpose of this study is to determine whether there is an influence on the application of the auditory intellectually repetition (AIR) learning model through lesson study for learning community on the problem solving abilities of students. This study uses a quasi experimental design method through the randomized posttest-only control group design using matched subjects. The study was conducted at Semarang 11 Public High School in the 2018/2019 school year. Based on the research, the results of statistical tests on the problem solving ability variable have a significance value (2-tailed) of 0.000 <0.05 so that it can be concluded that there are significant differences in students' problem solving abilities between the experimental class and the control class. The experimental class scored better than the control class, with the acquisition of the experimental class number of 76.96 and the control class of 65.94. Based on these results it can be concluded that the application of auditory intellectually repetition (AIR) learning models through lesson study for learning community can improve students' problem solving abilitiesKeywords: Auditory Intellectually Repetition (AIR) Learning Model, Lesson Study for Learning Community, Problem Solving

Purpose Problem solving is a skill in mathematics which although always relevant has heightened priority due to the changes in the new mathematics GCSE (Department for Education, 2013). It has previously been a skill which is deemed underdeveloped within mathematics and therefore is a theme which teachers are seeking to improve and nurture in order to align with the new changes. The GCSE is the formal qualification that students take at the end of Key Stage 4 (KS4) in the UK. The paper aims to discuss these issues. Design/methodology/approach The focus of the enquiry was to explore, using lesson studies, the differences in students’ approaches to problem solving. Consequently, key themes relating to the mediation of gender, ability, and academic motivation surfaced. Considering these themes, the paper subsequently reflects upon pedagogical practices which might effectively develop students’ ability to problem solve. The study took part in a mixed gender comprehensive secondary school with students taking part in the observation lesson ranging in age from 11 to 12 years old. The authors are the teachers who took part in the lesson study. The teachers implemented observation techniques in the form of video and peer observation with the accompanying teacher. In addition, students provided feedback on how they approached the problem-solving tasks through a form of semi-structured interviews, conducted via the use of video diaries where no teachers were present to prevent power bias. Following this, a thematic analysis of both the observations and student video diaries generated conclusions regarding how said key themes shaped the students’ approaches to problem solving. Findings Students’ frustration and competitive need to find a specific answer inhibited their ability to thoroughly explore the problem posed thus overseeing vital aspects needed to solve the problem set. Many students expressed a passion for problem solving due to its freedom and un-rigid nature, which is something teachers should nurture. Originality/value Generally, teachers are led by a culture in which attainment is the key. However, an atmosphere should be developed where the answer is not the key and students can explore the vibrant diversity mathematics and problem solving can offer.

Contextual Teaching

Differential equations is a branch of mathematics which is closely related to mathematical modeling that arises in real-world problems. Problem solving ability is an essential component to solve contextual problem of differential equations properly. The purposes of this study are to describe contextual teaching and learning (CTL) model in differential equations course, to improve lecturers’ abilities in implementing CTL, and to improve students’ problem solving ability in differential equations. The study was conducted in the fifth semester of 2015/2016 academic year with 34 students of mathematics education Universitas Muhammadiyah Surakarta as participants. The CTL model was applied by lesson study approach which involved three stages namely plan, do, and see in each cycle. This research was conducted in four cycles. The study results found that discovery-based CTL could be applied in differential equations course. The lecturer abilities to design discovery-based contextual learning plan, to present real-world problem in learning process, to design learning strategy and assessment instruments of problem solving improved significantly. Problem solving ability of students also improved during teaching and learning process.

Descriptive Method

The aim of this research is to improve the quality process, to develop creative thinking, and to create a good result of lesson study by implementing a problem solving method. This research is a class action research which involved 19 physcics students who enroll in matrik and vector space subject at even semester of 2017-2018. The data was collected by employing test and interview. It is analyzed by descriptive method. The result of this problem solving reseach are (1) giving the positive impact towards the ability of creative thinking (2) increasing the result of learning process (3) improving the ability of students to better understand the learning process and the ability to apply this problem solving  method in any types of problems, and (4) increasing students' learning activity. Based on the result of this research, it is recommended to implementing the problem solving method in any types of learning. The problem solving method is expected to be the answer of any problems in physics.

Purpose The purpose of this paper is to examine how teachers improve core instructional practices in teaching mathematics for problem solving through lesson study (LS). The core practices included launching a task, implementing a task, and orchestrating students’ solutions. Design/methodology/approach This study adopted multiple case study and survey methodologies. Each of three LS groups developed a research lesson on problem solving in algebra through Chinese LS, which includes collaborative planning and repeated teachings/debriefings of the research lesson with support from experts. The data collected included lesson plans, videotaped research lessons and debriefing meetings, and an end-of-project survey. Case studies supported by survey data were utilized to describe how research lessons were improved and what teachers learned from LS. Findings A fine-grained analysis of the data revealed that the participants improved their strategies for teaching for problem solving, which included effectively launching tasks, strategically implementing tasks, and productively orchestrating students’ solutions to the tasks. Further, analyses revealed that the feedback from experts during debriefing meetings played crucial roles in making these changes. Moreover, participants learned how to implement these core instructional practices and changed their views about students’ learning. Originality/value The study uncovers the mechanisms about how teachers improve teaching and their expertise in teaching through Chinese LS. The importance of the dynamic between repeated teaching and immediate feedback from knowledgeable others is highlighted.
