This study examines the subjects and concepts in biology perceived to be difficult to learn and teach by 759 pre-service biology teachers registered in the pedagogical formation program at Uludag University Faculty of Education in the academic year of 2005-2016, as well as the associations that word “biology” first calls to their mind. The study was designed as a survey model, and a questionnaire of three scaled questions was used as a data collection tool. The data were classified into 10 different categories based on different branches of biology: Anatomy-Morphology, Biotechnology, Ecology, Evolution, Physiology, Genetics, Histology, Cytology, Systematics and Reproduction and Development. Following the classification, the data were analyzed using frequency and percentages. The subjects and concepts perceived to be difficult to learn by the pre-service teachers are respectively as follows: photosynthesis and its stages, genetics, circulatory system, aerobic respiration, respiratory system, anaerobic respiration, protein synthesis, phanerogams, DNA structure and function, cryptogams, mitosis, plant systematics, endocrine system, meiosis, ETC, urinary system, plant physiology, taxonomy, evolution and digestive system. The subjects and concepts perceived to be difficult to teach by the pre-service teachers are respectively as follows: photosynthesis and its stages, protein synthesis, circulatory system, endocrine system, meiosis, plant systematics, evolution, mitosis, reproduction, genetic crossing over problems, Latinization of names, urinary system, genetics, ecology, aerobic respiration, DNA structure and function, plant tissues, glycolysis and anaerobic respiration. These findings confirm the need for developing undergraduate programs in biology and promoting the research culture at the secondary education level.

The Impact of an Interactive Approach on the Evolution of Moroccan University Students’ Conceptions of Neurotransmission
initial conceptions neurotransmission interactive approach conceptual change evolution...
Currently, it is taken for granted that teachers have to take into account the conceptions in order to achieve some efficient learning, the latter are generally resistant and may hinder the learning. Studies have shown that learning amounts to make conceptions evolve which play a determining role in the appropriation of scientific concepts such as neurotransmission, which is the subject of our study. This concept is present in the Life Science syllabus as early as high school. The aim of this study is to assess the impact of an interactive approach on the evolution of students' conceptions of neurotransmission. For this purpose, a questionnaire was administered to the first two years’ students (second year) in the Life Sciences stream at Dhar El Mahraz Faculty of Science in Fez during the academic year 2016-2017. This questionnaire was in the form of a pre-test and a post-test on learning/teaching of neurotransmission. The results of the study showed that the approach which was adopted had a positive effect on the evolution of the students' conceptions of neurotransmission in that it apparently contributed to a conceptual change for them.
Turkish Preschool Teachers’ Opinions on Aggression: Uncertainty of Relational Aggression
preschool teachers preschool children physical aggression relational aggression aggressive behaviors...
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.
The Effect of Metacognitive-Based Contextual Learning Model on Fifth-Grade Students’ Problem-Solving and Mathematical Communication Skills
contextual-based learning mathematical communication skills metacognition problem-solving skills...
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.
Enhancing Pre-Service Elementary Teachers’ Self-Efficacy and Critical Thinking using Problem-Based Learning
critical thinking pre-service elementary teachers problem-based learning self-efficacy...
Self-efficacy and critical thinking represent two vital components for university graduates in the 21st century learning. However, several studies reported that these two important outcome predictors were unsatisfactory. This study aimed at investigating the effects of problem-based learning (PBL) on pre-service teachers’ self-efficacy and critical thinking. A quasi-experimental nonequivalent pretest-posttest control group design was utilized. A total of 44 pre-service elementary school teachers (aged 19-22) at a private university in Indonesia were assigned as experimental (n = 22) and control (n = 22) groups. The experimental group learning received PBL, while the control group learning with traditional college instruction. The Self-Efficacy Scale (SES) and the Critical Thinking Questionnaire (CTQ) were administered before and after the intervention in both groups. Independent and paired samples t-tests were employed to analyze the pretests and posttests data. The results indicated that PBL was more effective in increasing self-efficacy and critical thinking of pre-service elementary teachers than traditional teaching. It is suggested that PBL should be used more frequently in science learning to further enhance students’ self-efficacy and critical thinking skills in higher education.
Construction of Students' Mathematical Knowledge in the Zone of Proximal Development and Zone of Potential Construction
construction of knowledge zone of proximal development zone of potential construction scaffolding...
This article highlights the main ideas that underlie the differences in potential pragmatic knowledge constructs students experience when solving problems, between the zone of proximal development (ZPD) and the zone of potential construction (ZPC). This qualitative research is based on a phenomenological approach to finding the meaning of things that are fundamental and essential from the ZPD and ZPC phenomena. Researchers observed mathematics learning by a teacher on 24 fourth-grade students who were divided into groups A (high IQ) and B (low IQ). Data collection through tests, observation, and interviews. While the validity of the data is done through triangulation of methods and triangulation of sources. The results showed that students of the Upper (A) group had high IQ but small ZPD and ZPC. In contrast, students in the Lower (B) group have low IQ but large ZPD and ZPC. This result means that intelligence (IQ) is measured not only logically-mathematically but also in the verbal-linguistic and spatial-visual fields. The conclusion is that there are differences in the construction of students' knowledge in the learning zone. This difference occurs because the knowledge constructs that the students have previously had an effect on the accommodation process of the schemes that students have built while in the proximal development zone (ZPD) where scaffolding works. Meanwhile, the potential construction zone (ZPC) is not sufficient to describe the real development of students. However, it only reflects what students have accomplished.
Exploring Biological Literacy: A Systematic Literature Review of Biological Literacy
biology education biological literacy theoretical concept systematic literature review...
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.
Building STEM Inquiry-Based Teaching Proposal Through Collaborations Between Schools and Research Centres: Students’ and Teachers’ Perceptions
genetic problems inquiry-based learning stem education students-teachers-scientists collaboration...
This study presents an inquiry-based teaching approach using a rich methodology involving STEM (science-technology-engineering and mathematics) projects, developed using a cooperative way to work between schools and research centres. We describe the teaching pattern scenario with students, teachers, and scientists. We also illustrate the learning process, conducted through two inquiry-based problems in Biochemistry, the mutagenesis process and the transgenesis effects caused by inoculation of bacteria. The teaching sequence, as well as the scientific knowledge and students’ competencies involved, are shown. We then analyse the students' and teachers' perceptions in this scenario regarding the development of students' STEM learning through their inquiry skills promoted and concerning predictors to vocational careers involved (students’ identities as potential scientists, scientific attitudes, social implications towards science or students´ agency). Finally, we add some conclusions and contributions to teaching STEM education, related to factors of the design teaching scenario that bring connections with the interests and motivations of students, such as the relevance of the projects to evoke understanding of processes or causal relationships of content or the teacher's professionalisation supported by a proper allocation between scientists and teachers.
The Relationship Among Problem-Solving, Coping Styles and Stress Levels of Parents of Children with Autism Spectrum Disorder, Attention Deficit Hyperactivity Disorder and Typical Development
parents problem-solving skills special-needs stress...
This research investigated the correlations among problem-solving, coping styles, and stress levels of parents of children with autism spectrum disorder, attention deficit hyperactivity disorder, and typical development. We used a correlational survey model design and collected the data with the Problem-Solving Inventory (PSI), the Ways of Coping Questionnaire (WCQ), and the Parent Stress Scale (PSS). The study group consisted of 350 parents. The research findings revealed that stress levels were negatively correlated with functional coping strategies and problem-solving. We found no significant difference between parents of children with Autism Spectrum Disorder (ASD), Attention Deficit Hyperactivity Disorder (ADHD) and typical development in terms of problem-solving approaches. Considering the relationships between the parents in terms of WCQ scores, there was no statistically significant difference in the subscales of self-confidence approach, submissiveness, optimistic approach, and seeking social support. Only the subscale of helplessness differed statistically based on the disability. Regarding the correlations between the groups in terms of stress levels, we found that the typical developmental group had lower PSS scores than the Attention Deficit Hyperactivity Disorder and Autism Spectrum Disorder groups. We believe that preventive support programs for stress management can make significant contributions to efficient coping methods and problem-solving.
Attachment Styles and Interpersonal Problems in University Students Living in Hostels: Mediating Role of Emotional Reactivity and Cutoff
attachment style emotional reactivity emotional cutoff interpersonal problem...
The current study investigated the mediation effect of emotional reactivity and cutoff between attachment styles and interpersonal problems. The gender differences were also determined. A sample of (N = 200) students living in hostels of two universities of Lahore was used. There were (N = 100) female in the sample. The average age of the participants was 22.3 (SD = 1.46). The results of the study showed a significant relationship between close attachment style, emotional reactivity and cut-off, and with subscales of interpersonal problems like too much aggressive, too much caring, too much dependent, socially inhibited, hard to be involved, and hard to be supportive. Similarly, anxious and dependent attachment style showed significant relationship with emotional reactivity and cut-off and with subscales of interpersonal problems of hard to be sociable, hard to be assertive, hard to be supportive, hard to be involved, too aggressive, much caring, too open and too much dependent. The mediation analysis using Structural Equation Modeling (SEM) revealed that emotional reactivity and cut-off showed partially significant mediation between attachment styles and interpersonal problems. Women showed more interpersonal problems as too open and too much caring compared to men living in hostels. The findings of the study have significant implications in the social structure of relationships in hostels, particularly in South Asian cultural context.
The Code of Conduct for Research Integrity, Governance, and Ethics in Education in the USA, Europe, and Ukraine: Comparative Analysis
comparative analysis research ethics research governance research integrity...
The purpose of the study is to identify how the coverage of topics of the Code of Conduct for Research in Education in Ukraine is consistent with the ones from the United States of America (USA) and Europe. Furthermore, the study attempts to explore coherences in the documents so that these could be reviewed and addressed. The study used the methodology for mixed-methods systematic reviews to respond to the first research question and the survey research methodology to respond to the second one. It was identified that the research integrity and ethics terms were not sufficiently covered by the Codes of education and research organisations from Ukraine compared to the Codes from the USA and European Union (EU). It was found that there was a shift from emphasising the role of the researcher (contributor) in the Codes from the USA and EU to drawing the importance of regulatory and legal instruments for the maintenance of research integrity and ethics in Ukraine. The prescriptive wording in the Codes of professional organisations in the USA and EU was given much greater attention than in the Codes of educational and research institutions in Ukraine. The Codes of the educational and research institutions from Ukraine were considered to be tentatively consistent with the relevant ones from the database from the USA, and Europe.

Metacognitive, critical thinking and opinion expression are in high demand. This study aimed to investigate the effects of the blended project- based literacy that integrates school literacy movement strengthening character education (literasi berbasis proyek terintegrasi GLS dan PPK: Li-Pro-GP) learning model on students' metacognitive skills, critical thinking, and opinion expression. A post-test experimental design was used to answer the research question. The study was conducted from August to October 2021 at Government Junior High School 23 Malang. Seventh-grade students were selected as research participants. The participants included 30 students from class VII-2. The research instrument was five essay questions to measure critical thinking skills. Material and assessment experts validated the essay questions developed by the researcher. The items that were declared valid were tested for validity. The result showed five valid items with high reliability of .670. Metacognitive skills were measured using the Metacognition Awareness Instrument (MAI), which consists of 40 items. The questions declared valid were tested for validity with a very high reliability of .953 for 37 items, and only three items were invalid. The ability to express an opinion was measured with an observation questionnaire validated by experts with a valid instrument score. Data analysis was performed by path analysis using the SmartPLS software. The results showed that the Li-Pro-GP blended learning model significantly strengthened students' metacognitive skills, critical thinking, and opinion formation.
Guiding Principles for the Use of Feedback in Educational and Psychosocial Interventions
design feedback framework intervention strategies...
Psychosocial and educational intervention approaches employ diverse treatment frameworks, most of which involve delivering some form of feedback to participants about their behavior. General conceptions of feedback are well-known to underlie mainstream therapeutic and educational approaches. Recently emerging ‘smart’ approaches also rely on feedback principles. However, little scholarship is available to stitch together evolving strands of feedback principles and no literature characterizes explicitly the diverse landscape of feedback practices employed in education or intervention science. This paper reviews intrinsic conceptions of feedback along with diverse cases of its use in intervention and education. Based on our consideration, we present a typology of feedback modalities that we hope will enrich the efforts of interventionists and educators to design treatment and educational frameworks incorporating feedback.
