{"title":"The The perceptions of Senior High School students and teachers about organic chemistry: A Ghanaian perspective","authors":"Esther Nartey, R. Hanson","doi":"10.33828/sei.v32.i4.8","DOIUrl":"https://doi.org/10.33828/sei.v32.i4.8","url":null,"abstract":"The purpose of the study was to determine the perceptions that senior high school (SHS) chemistry students and teachers have about organic chemistry as well as to compare organic chemistry topics that are difficult for students and teachers. Simple random sampling (lottery) and purposive sampling methods were used to select a sample of one hundred (100) SHS students who studied elective chemistry and ten (10) chemistry teachers. The research instruments used to collect data for this study were the ‘organic chemistry perceptions questionnaire for students’ (OCPQS) and ‘organic chemistry perceptions questionnaire for teachers’ (OCPQT). Descriptive statistics (frequencies and percentages) were used to analyze the data collected. The findings revealed that these SHS students have a fairly positive perception of organic chemistry while their teachers had a highly positive perception of organic chemistry. Preparation and chemical reactions of alkenes, preparation and chemical reactions of alkynes, structure and stability of benzene, reactions of benzene, comparison of reactions of benzene and alkenes, petroleum, polymers and naming of alkanes and structural isomerism were perceived by students as difficult to understand. The rest of the Ghanaian SHS organic chemistry topics (26 out of 34 topics) were perceived as easy to understand by students. Also, the teachers perceived all the SHS organic chemistry topics as easy to teach with the exception of reactions of benzene. The insights gained about teachers’ and students’ perceived difficult organic chemistry topics in this study imply that teachers’ perceptions and how these are communicated to students can have significant effects on learning. The authors believe that both teachers and learners could benefit from this increased awareness of perceptions about difficulties in teaching and learning organic chemistry. They therefore suggest that further studies into how teachers’ perceptions influence their teaching and consequently their students’ experiences be carried out. In addition, in future research, a diagnostic test based on the topics in the SHS organic chemistry syllabus could be added to ascertain whether the perceived difficult topics are actually difficult for students to answer questions on. This would help teachers to separate perceived difficulties from the actual difficulties (realities) and be able to address them in their lessons.","PeriodicalId":156311,"journal":{"name":"Science Education International","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126018694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 48 teachers (26 males and 22 females) teaching the chemistry component of science subject to 14- to 16-year-old students, in 48 schools affiliated to one district, were randomly selected for the study by taking one teacher from each school. One session was devoted for administering the questionnaire among the teachers and second session (with a gap of one day) was for addressing the teacher’s misconceptions. From the analysis of the responses, it was found that the two terms although they have the same meaning were misconceived as having different meanings. Due to this a misleading relationship between the two terms was discovered. Even the highest numerical value of valence was misconceived. The possible reasons for these misconceptions were identified. A simple, brief, and precise description of the concepts was presented to remove the misconceptions of the teachers.","PeriodicalId":156311,"journal":{"name":"Science Education International","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128212137","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A validated 40-item multiple-choice Ecological Knowledge Test (Cronbach's α = 0.759) was administered to 66 pre-service science teachers selected through convenience sampling. The results were analyzed through descriptive statistics, one-sample t-test, analysis of variance, path analysis, and non-parametric correlation tested at a 95% confidence level. The study results revealed that the pre-service teachers had ‘Above Average’ knowledge of ecology and its major, related, and other concepts. These concepts did not have significant differences among them but showed a significant effect on ecological knowledge. SHS strand did not show significant association with the said knowledge. Therefore, the pre-service science teachers were ecologically and environmentally literate. To increase ecological knowledge continually, they should be exposed to ecological and environmental immersion to gain awareness and knowledge and develop an in-depth appreciation for the ecosystems.","PeriodicalId":156311,"journal":{"name":"Science Education International","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126473902","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the correlational survey model was used. The sample of the research was composed of 193 (165 females, 28 males) prospective pre-school teachers studying in their first, second, third, and fourth year in a faculty of education of a state university located in the Black Sea in Turkey. Data were collected using the ‘Science Education Self-Efficacy Belief Scale’ developed by Riggs and Enochs (1990) and adapted into Turkish by Özkan et al. (2002) and ‘Kolb Learning Style Inventory’ developed by Kolb (1984) and adapted into Turkish by Evin Gencel (2007) in the spring semester of the 2019-2020 academic year. Descriptive and inferential statistics were used in the statistical calculations of the data in the study. As a result of the study, it was determined that these prospective pre-school teachers’ self-efficacy beliefs in science education were very high while their personal self-efficacy beliefs and result expectation sub-dimensions were at a high level. In addition, there is no statistically significant difference between prospective teachers' self-efficacy beliefs in science education, personal self-efficacy perception, and result expectation according to their learning styles. Based on the results obtained, to increase the success of prospective teachers in science and achieve desired goals in education, learning environments should be designed according to learning styles, and studies should be conducted to increase the quality of science education by making use of self-efficacy beliefs.","PeriodicalId":156311,"journal":{"name":"Science Education International","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131145913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Schools should be an environment propitious to the promotion of Education for Ethnic-Racial Relations, the teacher being an indispensable agent in this process. The present study is characterized as documentary research with a qualitative approach that sought to analyze, in a comparative perspective, evidence of a proposal for Education for Ethnic-Racial Relations present and/or absent in the Curriculum Guidelines and in the Common National Base for Initial Teacher Training (Resolution 2/2019), as well as the possible implications for the teaching of anti-racist Science and Biology in Brazil. The study leads us to conclude that the new Curricular Guidelines and the Common National Base for the Initial Teacher Training do not bring concrete evidence of an effective proposal for Education for Ethnic-Racial Relations as proposed by Resolution 2/2015, which was hastily revoked by Resolution 2/2019. The absence of these indications tends to result in negative implications for the teaching of anti-racist Science and Biology, since it was previously supported, we had found in the guidelines for teacher training an alternative to insert the study of ethnic-racial relations in undergraduate courses in the area. We hope that this study will collaborate for research in the area of ​​teacher training and ethnic-racial relations in the teaching of Science and Biology, especially for educational policies aimed at training teachers.","PeriodicalId":156311,"journal":{"name":"Science Education International","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125451711","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study analysed the data using the OECD’s three domain-specific competencies of scientific literacy, namely: i) explain phenomena scientifically, ii) evaluate and design scientific enquiry, and iii) interpret data and evidence scientifically. To assess the level of secondary students’ scientific literacy in these contexts, the study applied the scientific literacy assessment instrument called the ‘Nature of Scientific Literacy Test’ (NOSLiT), first developed by Wenning (2006). The results indicated that the level of scientific literacy of English students was higher than that of Malaysian students across all three domain-specific competencies. Despite the fact that NOSLiT is a systematic and reliable instrument for assessing the level of students’ scientific literacy, the study found that OECD’s three domain-specific competencies of scientific literacy provided better insights into the level of secondary students’ scientific literacy in Malaysian and English suburban schools. It is suggested that future studies should use a qualitative approach to both data collection and analysis to understand the level of students’ scientific literacy in more detail.","PeriodicalId":156311,"journal":{"name":"Science Education International","volume":"IA-20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126561143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study employed a descriptive correlation research design. Adapted instruments namely ‘Sources of Self-Efficacy in Science Course – Physics’ (SSSCP) and ‘Engagement in Physics Scale’ (EPS) were used to collect the data from the students. SSSCP was correlated with the scores of ‘Self-Efficacy for Academic Milestone-Strength’ scale for its validity. Reliability and validity of EPS was examined through Cronbach alpha and confirmatory factor analysis with acceptable results. Mean and standard deviation were used to answer the research questions while independent samples t-test, Cohen’s d, and Pearson r correlation were used to test the hypotheses. It was revealed that both male and female students have a high level of self-efficacy in the following: overall, vicarious experience, verbal persuasion, and performance accomplishment with an average level for the emotional arousal. Furthermore, a significant difference across gender was found only on the emotional arousal sub-level with a small effect size of 0.32. Moreover, positive correlation was found between overall self-efficacy and overall engagement as well as on cognitive engagement. On the other hand, a negative correlation was revealed between overall self-efficacy and emotional engagement. Focusing on increasing the self-efficacy of students in an online physics class should be practiced by teachers in order to increase engagement.","PeriodicalId":156311,"journal":{"name":"Science Education International","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114220175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The quasi-experimental design, specifically, the pre-test post-test control group type was used in this research to address the research questions. The research was carried out with 60 Biology teacher candidates. Achievement test and diagnostic test were used as data collection tools throughout the research. SPSS version 20 software was used to analyze the obtained quantitative data. Independent samples t-test was used to determine whether there was a significant difference between the control and experimental group students’ level of prior knowledge regarding the subject of protein synthesis. The findings revealed no statistically significant difference between the groups in pre-test (ρ > .05). However, the findings revealed a statistically significant difference between the groups, in the post-test, in favor of the concept map method used for the experiment group (ρ < .05). The increase in the post-test scores of the experiment group students indicated that the teaching method based on concept maps positively affected the students' academic achievement and elimination of misconceptions. Research indicated that students could not establish a correct relationship between the concepts of DNA, RNA, mRNA, tRNA, rRNA, nucleus, chromosome, gene, genetic code, codon, anti-codon, translation, transcription, ribosome, protein, and amino acid terms taught in protein synthesis subject. It was concluded that the areas of use for concept maps should not be limited as a teaching tool, but should be further extended to for determining misconceptions, eliminating misconceptions, and evaluating the instruction.","PeriodicalId":156311,"journal":{"name":"Science Education International","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124699363","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data was gathered from the freshman students (N = 68) who studied at the Department of Primary Education. Four measures were used in this case study: interviews, multiple intelligence inventory (MII), ecological intelligence scale (EIS), and students' 5-min notes. Correlation analysis was used to find the relationship between the students’ ecological intelligence and the types of MI. The responses to interview questions were coded into discrete themes. Findings indicated that the intelligence type which had the most correlation with the sub-dimensions of EIS was InterP. Moreover, moderate relations were determined between the sub-dimensions of EIS and the types of MI which were Bodily/Kinesthetic (BK) and Visual/Spatial (VS). Although the students had difficulties in activities such as drama and role-playing for BK intelligence, they enjoyed, and had better motivation to learn collaboratively during the activities through visual tools. Ecological intelligence relates to various types of MI. Based on this assertion the activities of MI should be integrated in-class environmental activities for students to acquire ecological awareness and sensitivity.","PeriodicalId":156311,"journal":{"name":"Science Education International","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127389743","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
