experimental science lesson

The aim of the current research is to the effect of applying the Reggio Emilia approach on the learning of experimental sciences in the third grade of elementary school. This research was conducted as a quasi-experimental method with a pre-test-post-test design and a control group. The statistical population of the research was formed by the third-grade students of Andimeshk City. Among them, the third-grade students of Modares boys' primary school were selected and randomly 50 of them were replaced in two experimental and control groups. The experimental group was inspired by the Reggio Emilia approach and the control group was trained with the usual method for 15 sessions. Data collection was done with the researcher-made test of the science lesson and functional checklist. Teachers and professors confirmed the validity of the tool and its reliability was obtained through Cronbach's alpha test of 0.865. The results of the multivariate covariance analysis showed that the Reggio Emilia approach increased the learning rate of third-grade elementary students in the science course in all three levels of facts, basic concepts, and skills. the use of learning in new situations and the whole has significantly increased. This study showed that by using the Reggio Emilia approach as an exploratory, formative, and constructivist approach, students' learning can increase in all three levels of learning and applying what they have learned in new situations).Therefore, it is suggested to use and check the effectiveness of this approach for other courses and educational levels of the elementary school.

Abstract

The aim of this study was to investigate the effectiveness of the reverse class approach on self-regulation of learning of experimental science course for fifth grade elementary school students in Kermanshah in the academic year 2021-2022.

The method of this study is applied in terms of purpose and in terms of data collection, it is a quasi-experimental research with pre-test-post-test design. The statistical population of this study included all fifth grade female students in Kermanshah in the academic year 2021-2022, from which 40 people were selected by available sampling method. The data collection tools were self-regulated learning questionnaires of experimental sciences. SPSS statistical software was used to analyze the research data.

The findings show the effectiveness of the flipped classroom approach on students' self-regulation of experimental science learning
 The results showed that there is a significant difference between the level of self-regulation of learning of science students who have been trained by experimental method and students who have been trained by control method.

The purpose of this research was to investigate the effect of group competitive training on the process skills of students in experimental science. The research method is quasi-experimental, usinga pre-test-post-test design with a control group. The statistical population consisted of all 2929 sixth-grade male students of the first district of the city of Urmia, 60 of whom were selected by cluster random sampling and divided into two experimental and control groups. They were exchanged at random. In this research, the process skills observation checklist measurement tool with confirmed content validity and reliability coefficient of 0.91 was used; The results of the data analysis showed that there is a significant difference between the mean scores of the students in the two experimental and control groups on the procedural skills and their seven components. Therefore, the teaching method of group competition on procedural skills was positive.
