Conceptual Structures

The importance of well elaborated cognitive structures in a science knowledge domain has been noted in many studies. Therefore, the main aim of this particular study was to employ a new diagrammatic assessment approach, students’ generated systemic synthesis questions (SSynQs), to evaluate and compare the quality of high school students’ and pre-service chemistry teachers’ cognitive structures in the organic chemistry domain. We used a mixed research sample (N= 83), and SSynQs were constructed following the high school chemical curriculum in the Republic of Serbia. Besides the overall quality of the cognitive structures, the size (extent) and strength (complexity) of the conceptual structures, as external representations of cognitive structures, were also analysed. It was found that both high school students and pre-service chemistry teachers had a substantial size of the conceptual structures, showing relatively good knowledge about IUPAC naming and structures of organic compounds, except for ethers. However, the strength of the conceptual structures, or inter-correlations between organic chemistry concepts, was evaluated as weak within high school students, and medium within pre-service chemistry teachers. This resulted in the identification of three main learning difficulties (LDs), accompanied by a lack of understanding (LU) about the chemical properties and relations of organic compounds. It was surprising to find that all identified LDs and LUs within high school students also appeared within pre-service chemistry teachers. What is more, the most desired and expected cognitive structures (distinguished multidimensional cognitive structures) without LDs and LUs appeared within high school students.

The Relationship

Although digital multimodal composing (DMC) is receiving increasing attention in language classrooms, the extent to which it contributes to students’ writing practices is controversial. In order to understand the affordances of DMC compared to traditional monomodal writing in school contexts, it is pertinent to compare DMC and traditional writing using academic integrated-skills tasks. The current study aims to investigate the relationship between the quality of Korean high school students’ multimodal composing and that of the same students’ traditional monomodal writing, as well as content and language alignment. Thirty-one Korean high school students carried out a summary-reflection task through DMC and traditional monomodal writing. After reading a short fable by Aesop, students summarized and reflected on the text. While students used only one mode in traditional writing (i.e. English text), they utilized multiple modes in DMC (e.g. pictures, movies). Students’ task outcomes were scored using analytic rubrics, and texts were coded in terms of the content and linguistic features students retrieved from the text (i.e. alignment) and their degree of reflection. The results showed that there were no statistically significant differences in the quality, content and language alignment, or amount of reflection in writing outcomes between students’ DMC and traditional monomodal writing.

The Relationship

The aim of this research is to determine the correlation between perceived class climate, motivation for achievement and school success among elementary and high school students. The research was conducted on a sample of 400 subjects. The instrument used for class climate survey is an Attitude scale, created as the combination of two instruments for measuring class climate. The MOP/D scale was used to survey motivation for achievement. The obtained results show that the quality of the overall class climate is not high, while the scores on the three dimensions of the class climate indicate that the students perceive Class Cohesion as the most favourable one, then the Teachers? Support and finally the Order and the Organisation. Significant differences in perceptions of class climate were found concerning age. Significant differences in perceptions of climate (both in the overall and in the Teachers? Support dimension) were also found with respect to the gender of the students. The findings indicate low positive correlations between perceived class climate and the motivation for achievement, and also between school success and the motivation for achievement. No correlation was found between the perceived class climate and school success. More detailed research shows that the climate dimensions Teachers? Support and Order and Organisation are significant predictors of the overall motivation for achievement and the Learning dimension, and that they are positively correlated. Learning and Persistence, the dimensions of the motivation for achievement, were found to be significant predictors of school success. A perceived class climate did not prove to be a significant predictor of school success, except for the Class Cohesion dimension, only on the subsample of high school students.

Teachers Perceptions

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.
