The identification of students’ mental models is crucial in understanding their knowledge of scientific concepts. This research aimed to develop a Mental Models Representation Instrument on Newton's Laws (MeMoRI-NL). The ADDIE (Analyzing, Designing, Developing, Implementing and Evaluating) model was used as a research method. The sample consisted of 30 students of 15-16 years-old at one of senior high school in Tatar Pasundan. The data was examined using Rasch analysis on validity, reliability, level of difficulty, and distributions of students’ mental models. Students’ mental models were classified as Scientific (SC), Synthetic (SY), Synthetic almost Misconception (SYM), and Initial (IN) model. Based on the evaluating stage, students’ mental models are mostly in the SYM and IN model. Consequently, it can be concluded that the Mental Models Representation Instrument on Newton's Laws (MeMoRI-NL) can be developed using the ADDIE model and most of the students' mental model has not been following scientific knowledge. Based on this research, teachers or educators should enhance students' mental models, especially for female students.

Mathematics is one of the most challenging subjects for many students. A similar problem is faced by special needs students, such as students with Autism Spectrum Disorder (ASD). Various instructional strategies are implemented by specialists to help ASD students understand mathematics in schools. To explore the impacts of an instructional strategy of mathematics on ASD students, the authors conducted a review of literature from 2011 to 2017 using various databases including ProQuest Digital Dissertations and Theses Full Text, Google Scholar, and Science Direct. A total of 39 articles were found. Most of the instructional strategy aimed to assist ASD students in solving mathematics problems. The implications of the study are also discussed in this literature review, which indicates that teachers need to use the appropriate instructional strategy to meet the needs of students with ASD and maximize their mathematics learning outcomes in schools.

Problem-solving and mathematical communication are essential skills needed by students in learning mathematics. However, empirical evidence reports that students’ skills are less satisfying. Thus, this study aims to improve students’ problem-solving and mathematical communication skills using a Metacognitive-Based Contextual Learning (MBCL) model. A quasi-experimental non-equivalent control group design was used in this study. The participants were 204 fifth-grade students; consisting of experimental (n = 102) and control (n = 102) groups selected using convenience sampling. This study was conducted in four Indonesian elementary schools in the first semester of the academic year 2019/2020. The Problem-Solving Skills Test (PSST) and Mathematical Communication Skills Test (MCST) were used as pre- and post-tests. In order to analyze the data, one-way ANOVA was used at the 0.05 significance level. The results showed that students in the experimental group had higher post-test scores than the control group in terms of problem-solving and mathematical communication skills. It can be concluded that the MBCL effectively promotes fifth-grade students’ problem-solving and mathematical communication skills. Therefore, it is suggested that MBCL should be used more frequently in primary school mathematics to further improve students’ problem-solving and mathematical communication skills.

Social media (SM) use is a rapidly growing phenomenon among Millennials. Thus, a growing body of studies have explored the beneficial applications and negative consequences of their use in an increasingly virtual world. The current study aimed to develop and validate a scale that measures university students’ motives for using SM from a psychological and social perspective. In Study 1 (N = 316), the psychometric properties of SM motives were examined. The estimated factorial structure was validated in Study 2 (N = 200). The Study 1 results showed two active personal motives scales (i.e., self-actualization and purposive motives), one passive motive scale (i.e., enjoyment), one active contextual motive scale (i.e., self-enhancement), and a contextual (neither active nor passive) motive scale (i.e., a factor of convenience). Study 2 findings confirmed this factorial structure. Construct validity was supported with significant differences between three types of users (i.e., productive, consuming, and disinterested) on their motives (151 words).

Research on critical thinking skills has been frequently carried out, but it has not shown maximum results. This problem is exacerbated by the differences in pre-service teachers’ academic abilities. A new learning model that can improve pre-service teachers’ critical thinking skills and reduce the gap in critical thinking skills among the upper, middle, and lower academic ability pre-service teachers is needed. This research aims at exploring the potential of the QASEE learning model on the critical thinking skills of different academic ability. This quasi-experimental research involved 107 pre-service teachers of Universitas Islam Negeri Raden Fatah, Indonesia. The research classes were divided into three classes, namely the QASEE class (experimental class), the RQA class (positive control class), and the conventional class (negative control class). Each class was further divided into upper, middle, and lower academic categories. The data were collected using an essay test supported by a critical thinking skill rubric. The data were analyzed by using ANCOVA and followed by LSD test. The research results show that the QASEE (Questioning, Answering, Sharing, Extending, and Evaluating) learning model can improve and equalize the critical thinking skills of pre-service teachers with various academic levels. Thus, the QASEE learning model can be used as a new reference to improve pre-service teachers’ critical thinking skills, especially the lower academic ability.

Learning models that can improve critical thinking, skills collaborate, communicate, and creative thinking are needed in the 21st-century education era. Critical and creative thinking are the two essential competencies of the four skills required in the 21st century. However, both are still difficult to achieve well by students due to a lack of thinking skills during mathematics learning. This study was conducted to determine the model of learning that is appropriate to develop students' critical and creative thinking skills. The study used three-class samples from eighth grade. The first class is given the problem-posing lesson; the second class is given contextual learning and third class as a control class. The results of the study indicate that improving students' critical and creative thinking skills are included in the moderate category for types using contextual learning and problem-posing. Also, it is found that contextual learning is more effective for improving critical thinking skills when compared with learning problem posing and expository learning. Meanwhile, learning problem posing is more useful to enhance creative thinking skills compared with contextual and expository learning.

Investigating critical incidents is one way to assist prospective teachers in expressing any developmental stage when accomplishing the teaching practice program. It is a significant component of reflective teaching in an educational framework related to continuing professional development (CPD), particularly self-directed learning. This study aims at exploring EFL prospective teachers’ field experience in cultivating their teaching competence through a critical incident analysis. A qualitative approach was applied. Three participants with different levels of English proficiency took part in this study by sharing their experiences through participating in and answering an interview and an opinionnaire. To analyze the data from the instruments, this study used descriptive analysis and coding techniques respectively. Results indicate that both negative and positive critical incidents contribute to the participants’ teaching development. The incidents support the learning process towards becoming a teacher and assist shaping their awareness of teacher identity. Further, the result of this study reveals that English proficiency level seems to take part in the strategy used for identifying critical incidents. This study implies that critical incidents provide a chance for prospective teachers to be more reflective. Thus, teacher education program stakeholders need to support critical incident analysis by giving relevant assignments while they are doing teaching practice, which in turn builds professional development in the context of prospective teachers.

The present study aims at investigating some English speaking problems found by the students of English language education department at State Islamic Institute of Kudus and exploring some implications for speaking curriculum development of English language education department. This study used a descriptive qualitative approach and the data were taken from semi-structured interviews, observation and focus group discussion (FGD). The results of the analysis reveal that the problems encountered by the students in English language education department in speaking English cover the lack of appropriate vocabulary, the lack of grammar mastery, the lack of correct pronunciation, the lack of input of English outside the class, the lack of confidence and the lack of English speaking curriculum development. There have been some implications for developing English speaking curriculum. First, the curriculum of speaking should be well designed. Second, lecturers should design English speaking curriculum integrated by technology and social media that makes students to enrich some culture, knowledge and experience around the world. Third, lecturers should facilitate the English speaking curriculum with the English speaking community so that the students will have more chance to speak English inside and outside the class.

The findings prove that (1) PP model with Indonesian realistic mathematical education approach is more effective than the PP and direct instruction models, (2) field-independent cognitive style is better than field dependent, (3) PP with Indonesian realistic mathematical education is as effective as the PP model, but more effective than the direct instruction model, and the PP model is more effective than the direct instruction model in each cognitive style, and (4) in the PP learning model with Indonesian realistic mathematical education approach, field-independent cognitive style is same skill as with field-dependent, but field-independent is better than field-dependent cognitive style in the PP and direct instruction learning models.

Using unplugged coding activities to promote computational thinking (CT) among secondary learners has become increasing popular. Benefits of using unplugged coding activities involve the cost-effective implementation, the ability to promote computer science concepts and self-efficacy in learning computer programming, and the engaging nature of active learning through collaboration. However, there is insufficient information regarding qualitative investigation on how learners develop their CT skills while working on unplugged coding tasks. This study therefore developed unplugged coding activities using flowcharts for high school students to learn computer science concepts, and to promote their CT skills. The activities consisted of five missions encompassing the concepts of sequence, repetition, input & variable, condition, and loop with condition. The data collection was carried out with 120 high students whose participation was video recorded and observed. A thematic analysis revealed that patterns of CT development started from initially developed, to partially developed and fully developed stages, respectively. The various stages were derived from different abilities to apply the computer science concepts to complete the missions with different expressions of CT skills. In addition, the study proposed a 3S self-directed learning approach for fostering the CT development, composing of self-check (in pairs), self-debug (in pairs), and scaffolding. It is therefore suggested to use the 3S model integrated with the unplugged coding activities for developing CT among high school learners.

The study aims to investigate the evaluation model of professional leadership and the characteristics of successful principals at an Indonesian secondary school. It is to further realize the effective learning and to produce instruments that meet the validity and reliability tests. It also aims to discover the correlation and the significance of the independent variables on the dependent variables, and the percentage of influence on the indicators in shaping the model of principals’ leadership. Quantitative data were obtained by distributing questionnaires to 100 students. The number of respondents was determined using a simple random sampling technique. The research findings showed that there was a significant correlation among the principals’ leadership, characters, and effective learning. It indicated that leadership evaluation influenced the school leadership and the principals’ characters on effective learning. The results of the measurement on formative relationships showed that the indicators of behaviour and actions of school principals who manage the teachers to conduct learning activity seriously in the classroom became a determining factor in shaping the effective learning paradigm in secondary schools.

This study was intended to display the role of eco-school program (Adiwiyata) towards environtmental literacy (EL) of high school students by analyzing, (a) EL of students in Adiwiyata and non-Adiwiyata high schools, and (b) EL of students in Grade X and XI, Adiwiya and non-Adiwiyata high schools in Malang-East Java, Indonesia. The survey involved 275 students. The respondents were from four state high school i.e. SMAN 1, SMAN 3, SMAN 4, and SMAN 7. Data were taken via MSELS questionnaire that was modified and filled online. Aspects of EL include ecological knowledge, environmental affect, cognitive skills, and behavior. The results of multivariate analysis showed that the level of students’ EL was significantly influenced by school type and grade. However, the interaction both of them had no significant effect on their EL. Univariate results on school type factor informed that significant differences occured in all aspects of EL, where the lower identified level of students in Adiwiyata schools compared to Non-Adiwiyata was only in the environmental affect. On the other hand, the significant influence of grade level only occurred in cognitive skills aspect. Broadly speaking, all data analyzes concluded that the application of the Adiwiyata program was able to bring a positive impact on the level of students’ EL. There was also a tendency that the higher the student's grade, the better their EL level.

The purposes of the current study were to develop students' spatial orientation skills using Virtual Mathematics Kits (VMK) and to evaluate VMK as a form of digital media in terms of spatial orientation. This study involved 42 lower-class and 47 higher-class elementary school students as the intervention group and 36 lower-class and 41 higher-class students as the control group. The intervention group was administered spatial orientation activities for 10 weeks. These activities were performed using a VMK to facilitate solving spatial problems. In the end of activities, spatial orientation instruments administered to compare spatial orientation ability on each group. The findings of this study, spatial orientation activities using a VMK improved students' spatial orientation skills. More specific, VMK provides more significant effect on higher-class students. Finally, VMK allows students to explore many ideas and perspectives to solve various spatial problems. VMK can be used as a digital media that helps students to develop spatial reasoning.

The ability to think critically and creatively is essential for students to be able to face the challenges of the industrial revolution 4.0.

The research data was taken by observation and interview methods. The data analysis method used is descriptive quantitative and qualitative methods. The results showed that two class action research cycles were well implemented. The application of the problem-based learning method can improve students’ critical and creative thinking skills. Students are able to solve a given case by doing the right analysis and being able to provide alternative solutions. Students consider the learning process to be more exciting and challenging. Students can express their opinions well in front of the class. The implication of this research is that lecturers can apply PBL with various combinations of learning strategies to improve students' critical and creative thinking skills.

Previous research suggests that non-cognitive factors play an important role in promoting success at school and beyond, aligning with the multifaceted goals of education. Enhancing students’ attitudes to learning in school is expected to have positive impacts on various schooling outcomes. To date, very few studies have focused on measuring and understanding students’ attitude to the arts. This study aims to address a gap in current research in this area by introducing instruments designed to measure attitude to dance, drama, music and visual arts. Confirmatory factor analysis and measurement invariance analyses are employed to examine the factorial validity and measurement equivalence of the scales of attitude to the arts disciplines for different ethnic groups in New Zealand. Findings support the utility of the scales as valid measures of attitude to dance, drama, music and visual arts. Noticeable differences are reported among New Zealand European, Maori, Pasifika and Asian students regarding their attitudes to dance, drama, music and visual arts.

Nowadays, teaching and learning activity employing the flipped classroom model has an important position in the process of providing education. This research aimed at identifying and analyzing articles examining the flipped classroom model that has been published in several reputable international journals issued in the 2010-2019 timeframe, which was conducted using bibliometric studies. The research was conducted using a 4-stages systematic mapping method: (1) searching for articles using the Publish or Perish application in the Scopus database, (2) classifying the articles for the bibliometric analysis, (3) checking and completing the metadata of those articles, and (4) conducting bibliometric analysis using VOSviewer application. The bibliometric analysis produced seven findings, as follows: (1) the trend of flipped classroom publications continued to increase from 2013-2019; (2) the ten most contributive journals has published 88 articles by 2019; (3) the ten most cited articles has produced 1,155 citations; (4) the three highest order of author keywords most widely used in flipped classroom articles were flipped classroom, active learning, and blended learning; (5) author collaboration with strong links only occurred in 21 authors through one document; (6) institutional collaboration with strong links formed through 28 collaborating institutions; and (7) state statistics were formed into three clusters and spread across various countries through contributions from authors who were in charge of 456 institutions. The flipped classroom model can be concluded as an educational model that is currently popular among researchers.

The implementation of Lesson Study (LS) varies considerably across countries and institutions and is still in a phase of adaptation and experimentation. This article explains the result and the process of a school-based initiative endeavor to implement LS at a suburban elementary in Padang, Indonesia. The study involved 13 teachers, the principal and 6 classes of students. The data were collected through observation and interview. They were classified on the basis of three noticeable emerging themes- teacher collaboration, scaffolding, and reflection. The data were analyzed qualitatively. The results of data analysis reveal a promising improvement in these aspects. Implementing school- support LS increased by weaving the concept into practice helped teachers develop their professionalism gradually. It was obvious that the teachers felt more at ease to work collaboratively when they designed the lesson. This also affected their design which showed more meaningful learning activities and challenging tasks. Then, the teachers improved the way they scaffolded the pupils. The content of reflection and the way the results of reflection were conveyed became better. The principal’s support and the teachers’ strong willingness to elevate their quality apparently took an important role. In spite of that, there were some challenges in carrying out collaboration, providing appropriate scaffolding, and doing reflection. Changing the teachers’ common practice to LS apparently needs some adjustment and time.
