In a first-semester general chemistry course, metacognitive training was implemented as part of an online homework system. Students completed weekly quizzes and multiple practice tests to regularly assess their abilities on the chemistry principles. Before taking these assessments, students predicted their score, receiving feedback after…

The study aimed at identifying the effectiveness of blended learning in improving students' achievement in the third grade's science in the traditional method. The study sample consisted of (108) male and female students, who were divided into two groups: experimental and control. The experimental group studied the units and changes of the…

This study investigated exam achievement and affective characteristics of students in general chemistry in a fully-randomized experimental design, contrasting Peer-Led Team Learning (PLTL) participation with a control group balanced for time-on-task and study activity. This study population included two independent first-semester courses with…

This research was conducted to investigate the effectiveness of BIOMIND portal in enhancing students' 21st century skills and overcoming their misconceptions in Biology subject. 118 Indonesian high school students were involved in this quasi-experimental study. The experimental group underwent learning experiences using BIOMIND portal whereas the…

Physics is all around us. It is present in the minute world of the atom and in the vast universe. There is physics in our everyday life. From the moment we arise to the time we go to sleep, our activities involve physics. When we cook our food, iron our clothes, wash the dishes, listen to the radio, or answer a telephone call, we make use of the…

The authors evaluated the effects of P-SELL, a science curricular and professional development intervention for fifth-grade students with a focus on English language learners (ELLs). Using a randomized controlled trial design with 33 treatment and 33 control schools across three school districts in one state, we found significant and meaningfully…

The purpose of the study was to assess elementary students' science process skills, content knowledge, and concept knowledge after one year of participation in an elementary Science, Technology, Engineering, and Mathematics (STEM) program. This study documented the effects of the combination of intensive professional development and the use of…

In the Community-Based Inquiry (CBI) instructional method, cooperative student groups complete case study activities based on scientific literature and conduct their own laboratory investigations that address authentic community needs. This study compared critical thinking and content knowledge outcomes between traditional Introduction to…

Assessments of U.S. students typically reveal stronger performance in science than mathematics yet their science performance remains uninspiring at best. Whether the metric considered is an international benchmark from TIMSS or PISA or the nation's NAEP report card, the mediocre portrait of U.S. science achievement has remained virtually unchanged…

Two experiments were conducted with developmental education students to investigate the impact of a contextualized intervention focusing on written summarization and other reading and writing skills. In experiment 1 (n = 322), greater gain was found for intervention than comparison participants on three summarization measures: proportion of main…

The purpose of this study is to compare the efficacy of three different approaches to professional development in Earth science education: preparing teachers to "adopt" expert-"design" curricula; preparing teachers to use a principled approach to design curricula; and preparing teachers to use a principled approach to "adapt" curricula. The claims…
