The effect of the strategies of Adel (I.D.E.A.L) and Rip (R.E.A.P)) on the achievement of biology and systematic thinking among second-year middle school students

Abstract

The research aimed to identify the effect of the strategies Adel (I.D.E.A.L) and REP (R.E.A.P) on the achievement of biology and systemic thinking among second-year middle school students. To achieve this goal, the researcher prepared an achievement test consisting of (30) items, and a system thinking test consisting of ( 30) multiple-choice items, and the research sample consisted of (100) students from the second intermediate grade in Iraq High School for Boys affiliated with the General Directorate of Education in Najaf Governorate, and the biology textbook prescribed for the academic year (2022-2023 AD), and by a random selection method it was chosen Section (A) represents the first experimental group that studied with the ADELE strategy (I.D.E.A.L.), Section (D) represents the second experimental group that studied with the REP strategy (R.E.A.P), and Section (C) represents the control group that studied in the usual way, relying on an experimental design with control. Partial, and the three research groups were rewarded according to chronological age, previous academic achievement, intelligence, and a systematic thinking test. After analyzing the results, the researcher concluded that the students in the first experimental group who studied according to the Adele strategy (I.D.E.A.L.) excelled and the students in the second experimental group who studied according to the REEP strategy (R.E.A.P.) ), on the students in the control group who studied according to the usual method of achievement and systemic thinking for second-year intermediate students in biology. The researcher recommended the necessity of using modern strategies based on problem solving, including the Adele strategy, and strategies based on reading comprehension, including the REP strategy, in teaching biology subjects, because of their clear impact on students’ achievement and developing their thinking, especially systemic thinking, in addition to establishing courses. Training for biology teachers and empowering them with modern strategies in teaching, including the (Adele) strategy and the (Rep) strategy, by knowing its steps and how to apply teaching through it.
