The amount of empirical research conducted in the area of differentiated instruction (DI) is overwhelming, necessitating this bibliometric analysis in order to produce an overview of literature on the topic. The objective of this study is to identify the characteristics of the most-cited educational research published on the topic of DI using science mapping and multi-dimensional bibliometric analysis methods. To answer the research questions which were related to: i) publication, ii) authorship, iii) authors’ keywords, and iv) journals, a total of 100 articles published between 1990 and 2018, generated from SCOPUS, were analysed. The results showed that the most-cited articles and the number of publications were highest between 1995 and 2011. With a total of 545 citations “A Time for Telling”, published in the Journal of Cognition and Instruction (1998), was the most cited. The most significant keywords were: a) differentiated instruction, b) differentiation, c) curriculum, d) mathematics, and e) reading. The analysis showed that there were 283 authors who contributed to the 100 articles, and amongst them Carol McDonald Connor was the greatest contributor. It was also revealed that the great majority of the most-cited publications were from Q1-ranked journals. These findings inform scholarly efforts adopted in developing a diverse knowledge base in the field. The findings are important to scholars as they provide an overview of the progress of research on the topic of DI.

The development of the revolution era 4.0 which increasingly rapidly demands the wider community to have the ability to think creatively mathematically. One effort to improve the ability to think creatively is through quality education. Quality education can be improved through to train thinking using the right learning model. This study aims to see which results are more effective in improving students' thinking skills between the two learning models applied. The two models are Problem Based Learning (PBL) and Aptitude Treatment Interaction (ATI) models. This research method uses quasi experimental method with a posttest only control test design not control group. This study uses two group subjects with two experimental classes. The analysis of the data used the hypothesis testing of the non-correlated 2-sample t-test. Based on the research results obtained Aptitude Treatment Interaction (ATI) models have a better effect on students' creative thinking abilities compared to Problem Based Learning (PBL) models.

The syntactic complexities of English sentence structures induced the Indonesian students’ sentence-level accuracies blurred. Reciprocally, the meanings conveyed are left hanging. The readers are increasingly at sixes and sevens. The Sentence Crimes were, therefore, the major essences of diagnosing the students’ sentence-level inaccuracies in this study. This study aimed at diagnosing the 2nd-year PNP ED students’ SCs as the writers of English Paragraph Writing at the Writing II course. Qualitatively, both observation and documentation were the instruments of collecting the data while the 1984 Miles & Huberman’s Model and the 1973 Corder’s Clinical Elicitation were employed to analyse the data as regards the SCs produced by the students. The findings designated that the major sources of the students’ SCs were the subordinating/dependent clauses (noun, adverb, and relative clauses), that-clauses, participle phrases, infinitive phrases, lonely verb phrases, an afterthought, appositive fragments, fused sentences, and comma splices. As a result, the SCs/fragments flopped to communicate complete thoughts because they were grammatically incorrect; lacked a subject, a verb; the independent clauses ran together without properly using punctuation marks, conjunctions or transitions; and two or more independent clauses were purely joined by commas but failed to consider using conjunctions. In conclusion, the success of the Indonesian and or other EFL students constructs sentences rests upon the knowledge, sensitivity and the mastery of complex syntactic structures through transformational/structural grammar.

This research aims to develop open ended-based worksheet in improving students' high-level thinking skills on static fluid materials. The method used in this research is Research and Development (R&D) with 3 steps namely, the initial stage, then the design and development of the product, and finally the product testing. The data analysis technique for product effectiveness is with the main field trials, namely (1) N-gain analysis, (2) paired t-test, (3) ANCOVA, and finally (4) effect size test. From the test results obtained information that conducted 10 students showed the results of the development worksheets obtained the average worth of development products by 90% this value is included in the very high category, while the student response of the average of 88% and also the readability response of 89% in the very high category. In the results of the n-gain analysis also show the value is0.70, that mean medium category. From the results of this study, it can be concluded that worksheets based on open ended can improve students' higher-order thinking skills. So, in further development we suggest that open ended-based on worksheet is not only applied to static fluid material, but also in other materials.

Summative assessment of students' writing predicts not only the extent to which the course learning objectives have been achieved but also reveals the relevance of the assessment design with the construct of writing being assessed. Any dichotomy between the assessment criteria and the construct of writing or between the assessment criteria and test scoring procedures can produce unreliable and invalid interpretations of the students' writing proficiency. Assuming cohesion as a measure of writing quality, the present study chose samples of academic writing which did not specify cohesion as a descriptor in the assessment scale. A cohesion index was, therefore, developed to investigate how cohesive devices created texture in the sample texts and correlated with the test scores. Descriptive statistics and non-parametric correlation analysis revealed that cohesive devices were positively associated with appropriate use to create texture; however, they only weakly correlated with the test scores. The findings imply that there is the need for developing assessment criteria which consistently measures the text-forming resources to reliably ascertain the writing proficiency of the students. The study recommends a research initiative based on an analytical assessment criteria to ensure a more accurate analysis of the role of cohesion in text-formation and writing quality.

This study aims to investigate the impact of using a LEGO Education program, specifically the “MoreToMath” kit, on the achievement of Deferent Levels of Elementary Students. The quantitative research design was used in this research study, and the participants were comprised of 120 elementary school students in the 2nd grade, in Amman, Jordan. A quasi-experimental research method and the MANCOVA were used, and a study tool to measure achievement was developed by the researcher for which the validity and reliability of achievement were verified. The results of the study show that there was a statistically significant improvement (α ≤0.05) in the achievement of the experimental study group, that studied using LEGO education, over the control group. There is also a statistically significant difference (α ≤ 0.05) between the arithmetic means of the three sub-groups of students’ previous achievement levels— high, middle, and low— and by using the Least Significant Differences (LSD) test we notice that there are significant differences between the high and low sub-groups, as well as between the middle and low. However, that there are no significant differences between the high and middle level sub-groups; and there is also no statistically significant interaction between the groups (experimental, control) and the levels of pre-achievement seen in the post-achievement levels. The study results indicate that the use of new technological tools, like the “MoreToMath” kit, may be beneficial in teaching mathematics as they tend to motivate students, and can lead to higher achievement for elementary students of different mathematics aptitude levels.

The objectives of this study were to analyze the validity, practicality, and effectiveness of South Kalimantan local wisdom-based biology learning and its effect on student learning outcomes. The research method used is research and development. This research was in a Develop stage of Thiagarajan’s Model. This development has produced learning models (lesson plans, student’s worksheet, learning achievement test questions, teacher activity sheets, student activity sheets, and student response sheets). The local wisdom-based learning model were designed with seven stages using Banjar language (regional language of South Kalimantan). Model that have been developed were tested for the level of validity, practicality, effectiveness, and its effect in learning. The level of validity is determined based on the assessment and review of the four validators. To find out the effectiveness and the effect of the learning model, quasi-experimental design was applied by involving two classes at SMAN 7 Banjarmasin-Indonesia. Data were collected using a variety of instruments, namely the validity assessment sheet, the student’s worksheet and lesson plan sheets, student achievement test questions, and student response sheets. Data analysis was implemented to measure the effectiveness and the effect of learning by calculating n-Gain and ANCOVA, respectively. The results, the learning tools met the "valid" criteria so that it can be implemented. Learning also concluded having good practicality criteria. Moreover, it can be seen that the application of local wisdom-based learning model and tools was quite effective in improving student learning outcomes, in contrast to learning in the control class. Furthermore, ANCOVA test concluded that there were significant differences in learning outcomes between students in the experimental and the control class.

This study aims at exploring the problem of the readiness and competence of new teachers to teach in primary schools. This study specifically focuses on identifying the readiness of new teachers to conduct teaching professionally, and analyzing their competence in conducting teaching. This study employs a mixed-method research design with data collected from two different approaches: a qualitative approach by conducting interviews and observation, and a quantitative approach by conducting a survey. The data were collected from lecturers, graduate teachers working as teachers, graduate teachers working not as teachers, and users of graduate teachers. The results of data collection and analysis were made into several themes. The results showed that the majority of graduates were ready to join the workforce as professional teachers with the risk that they had to accept the lack of welfare and legitimacy as unprofessional teachers because they had to attend further professional education programs. The education provided by the lecturers during their study in their institution in the aspects of knowledge and skills in the field of study and pedagogy became the foundation for new teachers in starting their careers as professional teachers in schools. A good educational process had produced teachers who have competencies with good categories in various aspects.

Teacher education has been innovated in Brunei to support the ongoing inclusive education and curriculum reforms. This survey investigated the development of essential instructional skills in initial Brunei trainee teachers. The sample consisted of 109 student teachers (71 females and 38 males). Significant mean scores (Mean ≥ 4, p< .05) and 95% confidence intervals were used to identify the levels of proficiency and enablers of success in teaching. Participants were proficient on 15 of the 28 skills measured by the Teacher Behaviors Checklist (Approachable; Confident; Effective communicator; Encourages; Enthusiastic; Flexible; Good listener; Humble; Prepared; Professional; Rapport; Respectful; Sensitive; Striving to be a better teacher; Understanding). From independent groups, T-tests and One-Way ANOVA analyses, other significant trends in participants’ performance emerged at p< .05 level of evaluation. Females scored highest on Humble and Realistic expectations while males scored highest on Understanding. Trainee teachers aged 31-35 scored highest on: Promoting critical thinking; and Providing constructive feedback, than counterparts. Participants with higher degrees (e.g. Master of Arts) scored higher on Authoritative skills than those with lower degrees (e.g. Bachelor of Arts). Trainees with teaching experience scored significantly higher on: Accessible; Knowledge about the subject matter; and Technological competence, than those with no experience. The findings suggest the need to help pre-service teachers to gain proficiency in all teacher skills to improve the quality of education in the country. Further research was recommended.

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.

The purpose of this research is to experimentally evaluate how the “flipped classroom” model used to deliver Business English, which is commonly an integral part to the ESP course at tertiary schools of Economics in Ukraine, to the students majoring in Economics fosters students’ critical thinking skills and improved their academic performances and what students’ perceptions of this model are. The learning environment used a multimedia-based textbook entitled “Business skills through English”. This was experimental research which used a mixed-methods approach. Students’ critical thinking skills and academic performance (learning outcomes) were the variables for this study. Placement tests, needs analysis questionnaires, Course Satisfaction Questionnaire, a test to assess the students’ critical thinking skills were used to collect the statistical data. Cronbach Alpha coefficient was applied to interpret the test on critical thinking data and SPSS AMOS statistical package programme was used to analyse the consolidated data. The study found that the “flipped classroom” model used to deliver ESP and Business English to the students majoring in Economics has the potential to provide a better learning experience for the students and teaching experience for the teachers. This model fosters students’ critical thinking skills by involving them in problem-solving-based learning and improves their academic performances by increasing their responsibility for learning results and stimulating them to use different learning styles. Overall, the above model substitutes a teacher-centered with a student-centered approach that engages learners in the true-to-life business world and language environment. In this way, learning Business English and ESP at higher educational institutions in Ukraine is a move from just training memory (memorizing professionalism-related English vocabulary and doing grammar drills) to applying language as a learning medium in the specifically designed vocational contexts.

This study aims to determine the effect of the application of the Search, Solve, Create, and Share (SSCS) learning model to the mathematical reflective thinking skills and the students' mathematical problem-solving abilities. This research is a type of Quasi-Experimental Design research with a 2x2 factorial research design. Data collection techniques in this study in the form of documentation and tests at Private school in Bandar Lampung with 28 students of experiment classes and 28 students of control classes. Data analysis techniques used are the normality test and homogeneity test. Testing the hypothesis in this study using the Multivariate Analysis of Variance (MANOVA) test. Based on the results of the study, The calculation of the MANOVA test, it was concluded that there was an influence on the application of the SSCS learning model to students' mathematical reflective thinking skills. The application of the SSCS learning model to the mathematical reflective thinking ability has an influence percentage of 91.9%. The application of the SSCS learning model to mathematical reflective thinking skills and mathematical problem solving abilities has a relatively high level of effectiveness.

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.

This research aims to reveal the pattern of the multiculturalism-based civics education at higher education institutions in Surakarta, Indonesia. It applied the descriptive qualitative method with the dual case study approach, conducted at State University of Sebelas Maret and Slamet Riyadi University in Surakarta. The data were collected through observation and interviews to find the answers to the research questions in the field. The data were analysed using the interactive technique, consisting of data collection, data reduction, data display, and conclusion drawing. The result shows that the teaching of multiculturalism-based civics education at State University of Sebelas Maret and Slamet Riyadi University has almost the same pattern, that is media-assisted teaching pattern and is always conducted by considering the material integration dimension, knowledge construction dimension, prejudice minimization dimension, equal rights to education dimension, and the dimension of school culture empowerment and social structure from the planning stage to teaching implementation and evaluation stages. The research findings suggest that the students of universities in Surakarta should be able to implement the goal of the teaching of civics education in universities, and the lecturers should always improve the materials, content, method, and strategies of the teaching of multiculturalism-based civics education.

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.

This study aims to design mathematical literacy instruments that have evidence of content and construct validity and are reliable for use as an Assessment for Learning. The research involved eight experts as instrument validators and 273 eighth-grade students of junior high school in Yogyakarta Province. The results showed that the ten mathematical literacy items developed had the V Aiken coefficient index calculated from 0.781 to 0.906 (> 0.75). The results of adequacy testing of samples with KMO and Bartlett show Chi-Square in the Bartlett test of 608,608, the p-value <0.05 and KMO value of 0.781 (> 0.5). The results of testing of the measurement model with Confirmatory Factor Analysis (CFA) produce a Root Mean Square Error of Approach (RMSEA) value of 0.049 (≤ 0.08), chi-s Square of 33.92 (<2df), the p-value of 0.05004 (≥ 0.05). Nine out of the ten items developed had t-value> 1.96, Standardized Loading Factor (SLF) was greater than the critical limit (> 0.3), and Construct Reliability (CR) of 0.78 (> 0.7). It can be concluded that the developed mathematical literacy instrument can measure what must be measured and nine items significantly reflect the construct or latent variable, as well as the level of consistency of a good score.

In the last decade, learning from computer-supported collaborative technologies has been combined with social media (SM) and this has gotten a lot of attention. Also, there is a growing body of literature that suggests that SM is gaining a lot of attention because it has the perceived pedagogical affordances that could be used as a potential tool for teaching and learning. These perceived pedagogical affordances allow people to interact, communicate, collaborate and share resources among others. Most of the studies published on SM in education have focused on higher education (colleges and universities) with a relatively small body of literature on secondary education. Despite the wide use of SM in education, its benefits are still not clear across studies. We conducted a systematic literature review using the EBSCOhost database. Screening of abstracts and full texts resulted in the selection of 10 papers for the review. Seven approaches to using SM in learning in high schools have been identified: (1) interaction, (2) information dissemination, (3) communication, (4) collaboration, (5) teaching, learning, and resource sharing, (6) socialization, and (7) entertainment. Most of the articles claimed that the educational use of SM has a strong positive effect on social skills, but the evidence presented was rather weak. Subject-specific outcomes were not in focus in using SM in education. All studies followed a constructivist philosophical perspective. Based on this we provide a theory-based scenario for using SM in learning social skills and subject-specific outcomes.

The aim of the study focused on assessing the relationship between student's financial knowledge and their relationship with the use and application of financial instruments. The test designed by Garcia-Santillan, Contreras-Rodriguez and Moreno-Garcia which integrates topics on money management, savings and investment, spending, credit and budgets, was used. 333 high school students were surveyed face to face and only 305 were validated. The internal consistency Cronbach’s Alpha of the scale was of α=.860 (34 items) and α=.855 (7 dimensions). For the hypothesis test, exploratory factor analysis and canonical correlational analysis were used. The main findings show the existence of three factors that explain the structure that underlies the phenomenon of financial knowledge and the use of financial techniques, and a significant relationship was found between the constructs of financial knowledge and the use and application of financial products.

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.

This research aims to test (1) the effectiveness between problem posing learning model with Indonesian realistic mathematical education approach and problem posing learning model on written mathematical communication skills, (2) the effectiveness between field-independent and field-dependent cognitive styles on written mathematical communication skills, (3) the effectiveness between problem posing learning model with Indonesian realistic mathematical education approach and problem posing learning model on the written mathematical communication skills from each cognitive style, and (4) the effectiveness between field-independent and field-dependent cognitive styles on written mathematical communication skills from each learning model. This quantitative research employed a quasi-experimental method. The research sample consisted of 240 fifth-grade elementary school students in Jebres District, Surakarta, Indonesia. Data collection techniques included tests of written mathematical communication skills and cognitive styles. The data were analyzed using prerequisite (normality, homogeneity, and balance), hypothesis, and multiple-comparison tests. 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.
