Cognitive Conflict Strategy and Simulation Practicum to Overcome Student Misconception on Light Topics

One way to reduce misconceptions can be overcome by cognitive conflict learning strategies with the help of simulation practicum instead of actual practicum. This study aims to determine whether there are differences in students' misconceptions before and after learning with cognitive conflict strategies as an effort to reduce misconceptions on light material. Research sample of 31 students. Data on the degree of misconception before the study was 0, 36 and after doing research was 0.17. The t-paired test results for the mean percentage of students' misconceptions on light material before and after learning differed at a significance level of 0.05. While, the results of N-Gain calculations to student achievement increase in overcoming misconceptions on light material were 0.3, that means the average students' achievement in dealing with misconceptions are in the medium category and cognitive conflict strategies combined with simulation practicum have a strong effect on reducing students' misconceptions on light material with a range of 2.91. Based on the results of the study it can be concluded that cognitive conflict strategies combined with simulation practicum can be used to reduce misconceptions that lead to increased student learning achievement. Further research is needed to explore students' misconceptions on other physics topics and can measure student misconceptions at each meeting so that students are more organized and developed in learning

Monetary misconceptions

The paper identifies a number of misconceptions about the monetary policy process and the monetary transmission mechanism in the UK. Among the misconceptions about the process are the alleged lack of regional and sectoral representativeness of the Monetary Policy Committee and the view that operational central bank independence means that monetary and fiscal policy are not properly coordinated. Among the transmission mechanism misconceptions, the "New Paradigm" figures prominently. Among the New Paradigm changes in the British economy that have been given prominence are the following: increasing openness; lower global inflation; lower profit margins, reflecting stronger competitive pressures; buoyant stock markets; a lower natural rate of unemployment; and a higher trend rate of growth of productivity. I argue that the New Paradigm has been over-hyped and misunderstood as regards its implications for monetary policy. Other misconceptions include the ''death of inflation'', the ''end of boom and bust'', a couple of Neanderthal Keynesian fallacies and the monetary fine tuning fallacy

Misconceptions about Calorimetry

In the past 50 years, calorimeters have become the most important detectors in many particle physics experiments, especially experiments in colliding-beam accelerators at the energy frontier. In this paper, we describe and discuss a number of common misconceptions about these detectors, as well as the consequences of these misconceptions. We hope that it may serve as a useful source of information for young colleagues who want to familiarize themselves with these tricky instruments.Comment: Submitted to Instrument
