Developing knowledge application competency for 12th grade high school students
through an organic chemistry exercise system that has some practical content

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.

This research, which was conducted in order to reveal the cognitive structures of high school students regarding the concept of energy through the word association test, was designed in a survey model. Word association test was used as a data collection tool. After the necessary information was given to the students, they were given three minutes and they were asked to write the first words that came to mind about the key concept. The study group of the research consists of 202 students studying in a high school in the province of Malatya in the 2019-2020 academic year. 58 of these students are 9th grade, 46 are 10th grade, 45 are 11th grade and 53 are 12th grade. While choosing the study group of the research, one of the purposeful sampling types was chosen based on easily accessible situation sampling. The words obtained related to the concept of energy are tabulated using Microsoft office excel program. The cut-off points of the tables, which were examined in detail and repeated words were taken into account, were determined. Concept networks were created in line with the determined cut-off points. In the research, 189 different words were produced for the concept of energy by high school students. While 114 of these words were not included in the analysis because they had 4 or less frequencies, 75 words were included in the analysis. Among the words included in the analysis, the most repeated word in the 9th grade was “petrol” (f = 30), the most repeated word in the 10th grade was “fossil fuel” (24), the most repeated word in the 11th grade “electricity” (19), the most repeated word in the 12th grade was found to be “potential” (28). In the comparison between the classes, a difference in quantity and quality is observed. It has been observed that as the grade level increases, the quality of the answers given increases.

Reading Comprehension Ability

The pedagogical usability is an important characteristic of applications that support learning as it relates to the added value students perceive while using it for learning. A good pedagogical usability means that an application has more chances to be accepted and used by the students thus raising the possibilities that students actually will learn with it. However important, this concept tends to be neglected by many authors. In this work we show how this concept can be applied to evaluate an application by presenting a real example of an application that has been re-designed to improve its usability, thus showing how pedagogical usability can be operationalized to be applied in general. The application shown in this work is called RedCoMulApp (Reading Collaborative Multiple-option Application) and its goal is to raise the reading comprehension ability of 12th grade high school students. In order to capture the pedagogical usability, we used 12 metrics to design a questionnaire with 26 questions to be answered with a 5-point Likert-scale, plus two open-ended questions to capture aspects that were positively valued, and those that should be improved. The results for the pedagogical usability allow us to validate that the design of the application was perceived by the students as pedagogically useful to learning about reading comprehension.

<em>The Innovate to Mitigate project designed and conducted a competition for students aged 13-18 to propose and test strategies for mitigating rising levels of greenhouse gases. This paper explores the scientific inquiry and interdisciplinary learning of a 12th grade high school team over 6 months of participation. We used an activity-theoretic approach as a framework for capturing and analyzing the structure of the learning system in the team, situated within a science competition. This approach provided a lens both for finding and analyzing team learning at several levels—conceptual, procedural, metacognitive—and for revealing the processes by which learning was mediated by the activity system.</em>

Citizenship and civic participation are spatially and temporally changing concepts, therefore, their research remains constantly relevant. The question of how 17–18-year-old pupils see their “place” in society and their role in political processes, is of high importance, as they are the future voters. The main objective of the paper is to find out the kinds of categories that can be distinguished in terms of civic participation among the youth on the threshold of adulthood and what are the specificities of these categories. Furthermore, I try to identify the dimensions along which young people interpret the concept of “citizen” and what are the qualities that they consider important to acknowledge someone as a “good citizen”. In this section, my aim is to highlight the influencing factors and their strengths. The results show that four types of pupils are distinguished in terms of participation: those who “accumulate” activities, the “traditionals”, the protesters, and the passive ones. At the same time, based on the responses, one can see that the characteristics of an ideal citizen are organized into three factors: orientation and activity, social, and responsibility. Their activities and ideas are greatly influenced by the environment and the behavioral patterns they encounter and follow. The study presents the results of a survey based on questionnaire, which is representative of the Hungarian 11th and 12th grade pupils of eight large cities in Transylvania.

The Cost

The purpose of this study was to explore the reasons 162 rural area high school students participate in the dual enrollment program. Dual enrollment programs allow high school students to enroll in college courses for credit prior to high school graduation with local school districts covering the cost of tuition. Participants in this study were recruited from two rural agricultural counties from Washington State attending a local college. Exploratory factor analysis revealed that dual enrollment participation was related to academics, financial, social, and choice reasons. Results showed no significant differences between 11th and 12th grade participants regarding financial and choice reasons to participate. However, statistically significant differences were found regarding academic and social reasons for participation. Implications for rural educators and recommendations for future research regarding dual enrollment programs are discussed.
