Online Module for Acid and Base Topic Based on 5E Model

Alternative conception or misconception is one of the problems that often be experienced by the students in science subjects including chemistry due to its abstractness and wide scope to be learned. Previous studies found that students often have misconceptions on strength of acid and base topic such as misconception in determining factor that affect the strength of acid and base, differences between strong and weak acid and base as well as the effect of strength of acid and base on conductivity. To overcome these misconceptions, an online teaching and learning module using 5E instructional model was developed. Analysis, Design, Development, Implementation and Evaluation (ADDIE) model is used for research and development. The module used interactive tools and medias to make students being active and understand chemistry well. This module was validated by five experts in term of module objectives, module content, usability, flexibility, learning activities and language aspects with average is ninety percent. The results prove that the module is very good and has high validity. Therefore, the application of online module for acid and base topic based on 5E (Engage, Explore, Explain, Elaborate, Evaluate) model is suitable to be implemented in online teaching and learning process.

Designing a Coherence- & Concept-Based Modular Course to Facilitate Students’ Understanding of Crosscutting Concepts

Crosscutting concepts (CCCs) are superordinate in the scientific concept system, common across disciplines, and very abstract. These characteristics, with the addition of incoherence in their curricular presentation, can challenge instructors. We designed a modular course based on coherence and conceptual understanding. The course structure was arranged in accordance with intra- and inter-unit coherence of CCCs, and each lesson was prepared according to “concept-based instruction” and the “5E instructional model.” The results of the pretest and posttest and the semi-structured interviews consistently showed that the participating high school students significantly improved their understanding of CCCs, thus supporting the effectiveness of the modular course.

5E INSTRUCTIONAL MODEL: A CONSTRUCTIVIST MODEL FOR TEACHING CHEMISTRY AT HIGHER SECONDARY LEVEL

Concepts of Chemistry are complex in nature and are hard to comprehend. To teach these complex concepts effectively, a modern constructivist instructional model can be a more appropriate choice. This study aimed to compare the academic achievement of students on posttest and retention test, taught through the 5E instructional model at the higher secondary level. The research design was pretest-posttest equivalent groups design. The sample consisted of 60 randomly selected students from the accessible population and was divided into two equivalent groups based on their pre-test score. The experimental group’s students were instructed through the 5E instructional model and the control group students were taught through the traditional lecture method for five weeks. Data was analyzed applying t-test at .05 level of significance. Data analysis showed that the experimental group outscored significantly than control groups on post-test as well as on retention test exhibiting the effectiveness of the 5E instructional model. It was concluded that although the 5E model requires more resources and time especially at the higher secondary level, however, it is recommended that this model must be used to teach Chemistry at the higher secondary level for improving academic achievement and better retention of knowledge.

THE ROLE OF MATH AND SCIENCE EXPOSURE ON THE EFFECT OF 5E INSTRUCTIONAL MODEL IN PHYSICS CONCEPTIONS

5E instructional model is commonly utilized in science teaching to promote conceptual learning. However, the benefit of 5E instructional model cannot be fully attained if the knowledge and skills essential to learning were not properly established from past. Similarly, the development of new concepts cannot be fully attained if the important processes inculcated in the 5E model were not considered in teaching. In this research, the effects of 5E model instruction and previous learning experiences on the conceptual learning of students in Newtonian mechanics were evaluated. Using 2 x 2 factorial research design, the conceptual understanding of 172 undergraduate students was evaluated before and after the experiment. These participants were distributed into four groups with different programs. The result revealed that both 5E instructional model and previous learning experiences contributed to the conceptual learning of students in mechanics. Those students who received 5E instructional model and whose exposure to science and math courses is high, gained the highest increase in the mean score after the experiment. This suggests that the effectiveness of 5E instructional model can be fully achieved if the knowledge and skills essential to learning and conceptual change were properly established from previous learning experiences and activities.

Effect of the 5E Instructional Model on Physics Academic Achievement Based on Gender and Students’ Ability: A Case of Berekum Senior High Schools in Ghana

This study examined the effect of the 5E instructional model on Physics students’ academic achievement based on gender and students’ ability. The study employed a quasi-experimental design using the pre-test, post-test and delayed-post administered instruments to the experimental and control groups. The study involved two instructional strategies (5E instructional model and traditional teaching). Instruments known as Physics Students’ Academic Achievement Test (PSAAT) and Delayed Post Test (DPT) were used to gather data for the study. Mean scores, standard deviations and normalized gains were used to analyses data while ANCOVA and independent-sample t-test were used to test the hypothesis at the 0.05 level of significance. A significant difference was found between Physics students instructed with the 5E instructional model and those taught through the traditional classroom. Similarly, a significant difference was found between Physics high-ability student in the 5E instructional group and those in the traditional group. However, a non-significant difference was found between Physics low-ability students in the experimental and the control groups. Similarly, a non-significant different was found among gender concerning pre-test and post-test means scores. However, a significant difference was found among gender in favor for the male students. The study recommended that Physics teachers wanting to improve their students learning outcomes should adopt the 5E instructional model.

Middle School Mathematics Classrooms Practice Based on 5E Instructional Model

The 5E instructional model is known for increasing student engagement and participation in the learning process. While viewing the video recorded lessons of middle school mathematics teachers, the researchers noticed teachers had a difficult time implementing the 5E model with fidelity. This case study explored the extent to which mathematics teachers used the 5E instructional model in their classrooms through analyzing video recorded lessons. The findings illustrate that the challenges of the teacher varied. They had difficulty finding activities related to the phases and moving away from a teacher-centered approach to a student-centered approach were identified as challenges of the teachers. The findings of this study inform educators about the difficulty’s teachers have in implementing the 5E model with fidelity. Also, the researchers elaborate on what phases need to be addressed specifically when teachers are provided professional development regarding lesson instruction.
