Analysis of the Effect of Learning Models and Gender on Students’ Critical Thinking Skills

This study analyzes the implementation of the Interactive Lecture Demonstration (ILD) model and the influence of gender on critical thinking skills in momentum and impulse. This study used a quasi-experimental with a pretest-posttest control group design. The research instruments were observation sheets and critical thinking skills tests. The analysis data were calculating the percentage of activity on the observation sheet, N-Gain, and independent-sample t-test. The results showed that percentage of learning in the experimental class (ILD) for teacher activities was 76% and for students were 77% in a good category. The control class (demonstration) for teacher and student activity was 77% in a good category. The average N-Gain of the experimental class was 0.62 and the control class was 0.55 in the medium category. The t-test results showed that there were differences in the improvement of students' critical thinking skills in the experimental class and the control class. Besides, gender has no effect on students' critical thinking skills in the experimental class. Meanwhile, in the control class, gender affects students' critical thinking skills. Thus, the implementation of the ILD model can improve students' critical thinking skills. Gender does not affect students' critical thinking skills in the ILD model.

Interactive Large Group Lecture Demonstrations: Dramatization of Medical Neurobiology Concepts to Improve Student Perception of Understanding Fluid Mechanisms of the Central Nervous System.

With the advent of recorded lectures, face-to-face teaching in medical school large classroom settings is increasingly under pressure to incorporate engaging activities that encourage attendance and can translate to greater attainment and long-term retention for learners, especially of "Generation Z" learning styles. This places a greater onus on lecturers to convey key concepts in a manner that holds value beyond their recorded substitute. The present article details several on-stage Medical Gross Anatomy and Neurobiology demonstrations that involve the teaching of an intuitive understanding of brain fluidic mechanics, such as hematoma formation and the protective functions of an intact cerebral spinal fluid system (addressing concussion and lumbar punctures). These demonstrations can be presented relatively quickly on stage and are suitable for engaging large classroom sizes (n > 100), which can be used in conjunction with traditional lecture formats. Ideally, these in-class demonstrations, together with the continued contributions of other quantitatively assessed demonstrations from other institutions, will help to maintain a growing body of large class face-to-face teaching approaches and strategies to help influence decisions regarding what basic medical knowledge may best be taught in class live versus by recorded substitute or other non-traditional lecture methods.

Development of The Conception of Mechanical Energy Conservation with Interactive Lecture Demonstration Method using Simple Experiments for Grade 7 Students

The purpose of this research is to develop a student's conception of mechanical energy conservation with the Interactive Lecture Demonstration method. The participants consisted of 19 students of class 7E SMP Muhammadiyah 1 Mlati in 2018/2019 academic year. The analysis of the student's sheet prediction showed that most students do not understand the conception of mechanical energy conservation. After learning applied, it is known that all students have understood the influence of the height of the object on potential energy, 18 of them have understood the influence of the mass of the object on potential energy. While students' understanding of changes in mechanical energy when objects fall and the influence of mass on kinetic energy has increased slightly. Through the Wilcoxon signed-rank test, it was concluded that there was an effect of the use of interactive demonstration methods on student learning outcomes in the matter of mechanical energy conservation conceptions.

A perspective on Interactive Lecture Demonstrations as a computer supported collaborative learning (CSCL) activity

Active learning designs that leverage the power of information and computer technologies (ICT) can vary tremendously in how they engage students – individuals, small groups or whole class. Interactive lecture demonstrations (ILDs) are instructor-led activities which engage the whole class and are designed address students’ mental models of core concepts in the discipline. The use of ICT allows for real time experiments conducted using sensors, simulations and even data analysis as the core of the activity. In this perspectives paper, we analyze the features of traditional ILDs through the lens of the field of computer supported collaborative learning (CSCL).

Let’s Repair the Broken Galileo Thermometer

We have developed and verified laboratory work as guided inquiry for upper secondary level students, focusing on conceptual understanding of the physical principle that forms the basis of temperature measurement,and on improvement of selected skills. Conceptual pre-test questions initiate the students’ interest and help identify input misconceptions. Using the method of interactive lecture demonstration, the students are introduced to the measurement principles of the Galileo thermometer. The students are then set the problem of how to repair a broken thermometer when tap water is used instead of ethanol. Since the density of water is greater than that of ethanol, the buoys must be adjusted by the students to achieve correct temperature measurement. The next steps of the activity have a hands-on orientation. The students work in pairs, guided by worksheet instructions. At the end of the activity, they complete self-assessment rubrics focused on skill improvement and final conceptual understanding. The results of the conceptual pretest questions and of the self-assessment rubrics from 461 participants are analysed and recommendations are made for teachers.

Do Active Learning Approaches in Recitation Sections Improve Student Performance? A Case Study from an Introductory Mechanics Course

Abundant research leaves little question that pedagogical approaches involving active student engagement with the material, and opportunities for student-to-student discussions, lead to much better learning outcomes than traditional instructor-led, expository instructional formats, in physics and in many other fields. In introductory college physics classes, some departments have departed radically from conventional lecture-recitation-laboratory course structures, but many, including my own, retain the basic format of large-group classroom sessions (lectures) supplemented by smaller-group meetings focused on problem solving (recitations) and separate laboratory meetings. Active student engagement in the lectures is encouraged through approaches such as Peer Instruction and Interactive Lecture Demonstrations, and these approaches have been demonstrably successful.

Effect of Collaborative Learning in Interactive Lecture Demonstrations (ILD) on Student Conceptual Understanding of Motion Graphs

To assess effectively the influence of peer discussion in understandingconcepts, and to evaluate if the conceptual understanding through Interactive Lecture Demonstrations (ILD) and collaborative learning can be translated to actual situations, ten (10) questions on human and carts in motion were presented to 151 university students comprising mostly of science majors but of different year levels. Individual and group predictions were conducted to assess the students’ pre-conceptual understanding of motion graphs. During the ILD, real-time motion graphs were obtained and analysed after each demonstration and an assessment that integrates the ten situations into two scenarios was given to evaluate the conceptual understanding of the students. Collaborative learning produced a positive effect on the prediction scores of the students and the ILD with real-time measurement allowed the students to validate their prediction. However, when the given situations were incorporated to create a scenario, it posted a challenge to the students. The results of this activity identified the area where additional instruction and emphasis is necessary.
