Aggression in early childhood is considered to a common problem. Identification, reduction and prevention of aggression, especially in early childhood are also considered prevalent. Preschool teachers are known as one of the most important people in children’s lives as they are the first ones to meet the child after parents. Therefore, they hold an important role in identifying, reducing and preventing child aggression observed in early childhood. The purpose of the present study is to examine the knowledge and the awareness levels of preschool teachers about aggression and aggressive behaviours. The study is based on phenomenological approach, as one of the qualitative research designs. A semi-structured interview form, prepared for the study based on expert opinions, was applied to the participants. On the light of the findings from the preliminary findings, the related form was applied to a second group of teachers over the internet. Besides, an additional scale consisting of the items of two different instruments directed to determine the aggressive behaviours of preschool children were formed and applied to the second group of participants. The last scale, which was prepared depending on the findings obtained from the second group of teachers, was applied to a third group of participants because the first two participant groups could not recognize and define relational aggression. The relevant themes and sub-themes were created from the data obtained and the findings were discussed within the scope of the literature. According to the results of the study, it was seen that preschool teachers generally defined aggression as physical and verbal harm, and similarly, aggressive behaviours were categorized under physical aggression and verbal aggression types. It was determined that teachers generally recognized relational aggression when they saw the items related to it in the scale. However, they hardly emphasized it while they were defining aggression. So, it can be said that preschool teachers have limited knowledge and awareness of relational aggression as they recognize it only when they see it but can neither define nor name it. The results are discussed and some suggestions are recommended.

This research aimed to analyze the levels of agreement between kindergarten teachers and principals in identifying the assessment of teachers’ teaching competencies and performance. The study was designed under a quantitative approach using a survey. It implemented a non-probability sampling technique with purposive sampling. The sample of the population comprised of 173 kindergarten teachers and 101 principals in Semarang District, Indonesia, or a total of 274 respondents. The data were collected through a questionnaire and analyzed using Cohen’s Kappa coefficient to measure the levels of agreement between raters and Pearson Chi-Square test was also utilized to determine the differences in perceptions among principals and teachers. The findings showed that the levels of agreement between raters were averagely in the no agreement category, implying the existence of differences in perceptions among teachers and principals. The involvement of a multi-rater strategy in such research is a rare effort, especially for the Early Childhood Education (ECE) level in Indonesia. Researches regarding teaching competencies and performance generally only involve single rater, either teachers or principals who judge themselves on their competencies and performance, thus the results tend to be subjective. In conclusion, the assessment of teaching competencies with the relation of cognitive abilities was conducted through a test that considered subjective questions and case analysis to evaluate the teachers’ skills based on their performance and self-description. Both personal and social assessments utilized self-assessment forms or autobiographies, which were completed with specific themes. Meanwhile, the performance assessment was observed with the assessment rubric and comparison with the learning process performed by an individual educator.

A large number of articles in the field of science education reflect on scientific literacy as the main goal of science education (SE), although often with varying viewpoints. Nevertheless, researchers have begun to highlight subject-specific teaching practices that are expected to specifically enhance science subject teaching, including biology. The main aim of this theoretical article is to come on consensus and to conceptualise the term biological literacy (BL) more clearly and to present a theoretical concept of BL, composed on the basis of systematically analysed articles. This theoretical concept includes two dimensions of BL: (1) cognitive (cognitive skills, conceptual understanding, biological inquiry) and (2) affective dimension, based on systematic literature review (SLR). This theoretical concept also includes in addition four dimensions of BL: (3) sustainability; (4) interdisciplinarity, (5) career awareness and (6) nature of biology (NOB), based on literature review (LR) of recent decades, that was conducted to write theoretical overview of this research.

While previous studies on assessments focused on measurement of principles and constructs, existing attention is given to content validation involving vocational education and skills. The emphasis on content validation has prompted a holistic perspective of teaching and learning to demand alternative research approaches. Using evidence of content validity based on expert judgment and assessment items, this paper argues that vocational knowledge and skills could be determined via constructs and construct functions. Content validity analysis was studied in two major phases, namely, through an assessment of an electrical technology course at a Malaysian higher education institution and expert panels’ examination of items. It was found that to increase confidence in providing reliable instruments for future empirical studies, a careful process in item development and content validity analysis was considered important. Therefore, applying these findings on item analysis and expert panels to reflect content validity can enhance the validity of assessment items.

Research on instructional quality has been of great interest for several decades, leading to an immense and diverse body of literature. However, due to different definitions and operationalisations, the picture of what characteristics are important for instructional quality is not entirely clear. Therefore, in this paper, a scoping review was performed to provide an overview of existing evidence of both generic and subject-didactic characteristics with regard to student performance. More precisely, this paper aims to (a) identify both generic and subject-didactic characteristics affecting student performance in mathematics in secondary school, (b) cluster these characteristics into categories to show areas for quality teaching, and (c) analyse and assess the effects of these characteristics on student performance to rate the scientific evidence in the context of the articles considered. The results reveal that teaching characteristics, and not just the instruments for recording the quality of teaching as described in previous research, can be placed on a continuum ranging from generic to subject-didactic. Moreover, on account of the inconsistent definition of subject-didactic characteristics, the category of ‘subject-didactic specifics’ needs further development to establish it as a separate category in empirical research. Finally, this study represents a further step toward understanding the effects of teaching characteristics on student performance by providing an overview of teaching characteristics and their effects and evidence.

The primary objective of this study is to require the experts’ unanimous agreement on the e-learning antecedents and usage behavior towards e-learning performance. This study used the Fuzzy Delphi Method (FDM) to gather answers and feedback using a 7-point Likert scale. The survey (items) was reviewed and approved by eight panel members or experts. It was analyzed using Fuzzy Delphi Logic (FUDELO 1.0) software. The data were evaluated using triangular fuzzy numbering and the position (ranking) of each variable was established through defuzzification. The findings revealed that all of the items received high levels of expert agreement, significantly greater α-cut defuzzification values >.5, the overall value of the threshold (d) is less than .2 and had to comply with the overall percentage of percent consensus, which must be greater than 75%. All 45 recommended items were retained adequately and acceptable for a large-scale survey in this study. Finally, each item was prioritized (ranked) based on the defuzzification value, and then some additional items were added, as recommended by experts.
