Abstract

This study aims to investigate the enhancement of students cognitive learning outcomes through the integration of Nearpod-assisted Problem-Based Learning (PBL) in carboxylic acid material, as well as to describe students activities, their ability to complete worksheets, and their responses to the use of this media. This study employed a pre-experimental method with a one-group pretest-posttest design and involved 48 fourth-semester students in the Organic Chemistry II course. The results indicate that learning activities were carried out very well (88.76%), students ability to complete worksheets was also high (average score: 88), and cognitive learning outcomes improved moderately (N-Gain: 0.63), with the highest achievement at the analysis level (C4). A total of 98.3% of students responded positively to the use of Nearpod in learning. These findings indicate that integrating the PBL model and Nearpod is an innovative and effective approach to enhancing cognitive learning outcomes, active participation, conceptual understanding, and higher-order thinking skills while highlighting its potential to improve the quality of chemistry education, particularly on abstract topics.

Abstract

Low student learning outcomes are often caused by limited student participation and the use of teacher-centered learning approaches. This study aims to determine the effectiveness of the Think Pair Square (TPSq) cooperative learning model assisted by stick media in improving student learning outcomes, particularly in the topic of chemical compound nomenclature. The research used a pre-experimental one-group pretest-posttest design with participants from class X-10 students at a senior high school (N=32). Learning outcomes were measured using tests given before and after the implementation of the model. Data were analyzed using a non-parametric Wilcoxon test. The results indicated a significant improvement in student learning outcomes, with an N-Gain score of 0.71 (high category) and an effect size of 3.85 (very strong category). The TPSq model, supported by stick media, encouraged students to think, discuss, and share ideas actively, leading to a deeper understanding of the material. In conclusion, the stick media-assisted TPSq learning model is effective in enhancing student learning outcomes in chemical compound nomenclature.

Abstract

The development of virtual laboratory(VL) has been widely used in secondary school teaching, notably science education. However, the development of VLspecifically for university-level education remains quite limited. In addition, in some practical disciplines, such as membrane-based separation chemistry, both lecturers and students face restrictions in equipment and resources. As a result, the goal of this study is to develop a VL for membrane synthesis practicum utilizing the phase inversion approach that can also be utilized in separation chemical practicum. In addition, the researchers assessed the amount of legitimacy and user response to VL media, specifically among students. This work follows research and development based on ADDIE (Analysis, Design, Development, Implementation, and Evaluation) framework. The first phase is begun with an analysis (via interviews) to investigate the lecturers issues and needs. Consequently, the analysis confirmed that the development of VL in separation chemistry is very essential. The researchers used feedback from the lecturer during the design stage, namely while gathering the material and presentation of VL to create the storyboard. Then, three experts confirmed the draft created during the development stage, declaring it highly validwith a proportion more than 85%. Face validity and construct validity took major revision to achieve 100% of highly valid. Following the revision steps of draft I (initial version) based on the validation results, draft II (revised version) was created for restricted testing with users (students), and the results revealed a very good response, with more than 90% of students providing feedback ranging from agree to highly agree. Their responses represent the impact received from VL, particularly in digital literacy, building critical and creative thinking, and learning flexibility. Some suggestions for enhancement, particularly the usage of foreign languages in VL, will be considered in the final stage. Thus, the VL can be recommended for use in membrane synthesis experiments in the separation chemistry course.

Abstract

This study was conducted to delve into the nuanced perceptions surrounding specific sachet water brands Tex, Daramy Pure Water, Blue Diamond Water, Arjorkoh Pure Water, and Nice Pure Water within the dynamic landscape of Bo City in Southern Sierra Leone. Bo City, a vibrant hub, witnesses local suppliers' consumption and sale of numerous sachet water brands. A meticulously crafted checklist of questionnaires was administered to comprehensively capture the multifaceted perspectives of residents. The survey encompassed a spectrum of aspects, including participant profiles related to sachet drinking water, knowledge about various brands, preferred consumption times, motivations behind choosing sachet water, consumption rates across different brands, taste preferences, confidence levels in producers, and the underlying rationale for brand selection. This multifaceted approach aims to provide a holistic understanding of the diverse factors influencing sachet water preferences and consumption patterns among the local populace. Analyses of the results revealed that most respondents chose Tex 82(41%), followed by Blue Diamond 42 (21%), Arjorkoh Pure Water 40 (20%), Daramy Pure Water 23 (12%), and Nice Pure Water 13 (7%) being the least. The study also revealed that most people's choices were based on the following parameters: Safety 82(41%), availability 47(23.5%), and good taste 34 (17%), among other parameters. A recent Canadian study of more than 1,000 citizens found that satisfaction with water quality is linked to taste, odor, and color. The research also revealed that few sachet water brands have no outlets in strategic locations within the city, and the taste of the water was a key factor, the consumption was high during the dry season of the year, and this is reflected in the annual sales record by the suppliers. From the data available at the time of writing, we concluded that Tex is the first preference of the customers, followed by Blue Diamond, Arjorkoh, and Nice Pure Water, being the least due to their taste, color, and availability.

Abstract

Literature review is the process of collecting, analyzing, and synthesizing information from various sources that are relevant to a particular research topic. These sources can be scientific journals, books, articles, research reports, or other credible sources. In college, the task of evaluating literature is very common. Students are often asked to conduct literature reviews as part of their coursework. This study aims to find out how students understand and carry out literature review tasks. For this reason, the researcher directly observed 4th semester students of Chemistry Education UNM who were working on literature review assignments. The researcher collected data from their assignments and also the results of the surveys they filled out. By analyzing this data, the researcher wanted to find out to what extent students understood this assignment, what difficulties they faced, and what they thought about the literature review assignment. The results of the study showed that students generally showed a very good category in using language according to writing rules. Meanwhile, for the level of understanding of the topic, completeness of literary sources, and analysis of literary content, they had shown a good category. However, in writing references to the results of the literature review, students only showed a sufficient category. The survey showed that the literature review assignment helped most students in analyzing information and finding relevant sources. However, many students have difficulty in grouping information, making in-depth conclusions, analyzing information, reading many articles, and understanding unfamiliar language. These difficulties make it difficult for test takers to focus on completing literature reviews. This indicates that lecturers need to improve the way they give literature review assignments and apply more effective teaching strategies to help students understand how to review literature well, so that students are more trained in critical and systematic thinking.
