In recent years, a consensus has emerged among researchers that teacher quality matters enormously for student performance. Students taught by more-effective teachers learn substantially more over the course of the year than students taught by less-effective teachers. Yet little is known about what makes for a more-effective teacher. Most research…

Electrochemistry is found to be a difficult topic to learn due to its abstract concepts that involve the macroscopic, microscopic and symbolic representation levels. Research showed that animation and simulation using Information and Communication Technology (ICT) can help students to visualize and hence enhance students' understanding in learning…

Testing to build research-based evidence to support teaching methodologies that promote student learning has become increasingly important in a standards-based educational system in the United States. One challenge is the lack of studies that support specific methodologies so teachers and administers can make professional development and…

This article reports analysis of data collected from a quasi-experimental study in 2 Canadian late French immersion science classes. We examine if, how, and when the first language (L1) is used when students in the first years of their second language learning talk about complex science concepts. We compare differences in groups following a…

This column focuses on promoting learning through assessment. In 1999, a group of researchers from Indiana University and Purdue University decided to investigate data about students' ideas in science by inviting National Science Teachers Association members to participate in a research study about children's conceptions of animals. Published in…

Using an action research model, biology faculty examined, implemented, and evaluated learner-centered instructional strategies to reach the goal of increasing the level of student achievement in the introductory biology course BIO 181: Unity of Life I, which was characterized by both high enrollments and a high DFW rate. Outcomes included the…

It is a common complaint among teachers that students forget what they have learned soon after taking a test. The phenomenon is seen in both secondary and undergraduate chemistry courses. This study examines the length of time after a test that students in three different chemistry courses (undergraduate nursing, nonscience majors, and high school…

Predictive relationships among perceived family processes, intrinsic and extrinsic motivation, incremental beliefs about intelligence, confidence in intelligence, and creative problem-solving practices in mathematics and science were examined. Participants were 733 scientifically talented Korean students in fourth through twelfth grades as well as…

This study examined the science and mathematics achievements of 16 Year 9 students with hearing loss in an inclusive high-school setting in Western Australia. Results from the Monitoring Standards in Education (MSE) compulsory state tests were compared with state and class averages for students with normal hearing. Data were collected from three…

This study investigated students' learning environment preferences and compared the relative effectiveness of instructional approaches on students' learning outcomes in achievement and attitude among 10th grade earth science classes in Taiwan. Data collection instruments include the Earth Science Classroom Learning Environment Inventory and Earth…

This article illustrates how test specifications based solely on academic content standards, without attention to other cognitive skills and item response demands, can fall short of their targeted constructs. First, the authors inductively describe the science achievement construct represented by a statewide sixth-grade science proficiency test.…

This study examines middle school students' learning and motivation as they engaged in a new media enriched problem-based learning (PBL) environment for middle school science. Using a mixed-method design with both quantitative and qualitative data, we investigated the effect of a new media environment on sixth graders' science learning, their…

Despite calls for investigations that explore the efficacy of integrating literacy into science instruction, few researchers have conducted this cross-disciplinary research. Therefore, this study focused on determining the impact of a literacy-based approach to teaching science on secondary students' attitudes toward science and their achievement…

One chronic challenge facing professional development providers is the need to convene and support groups of role-alike K-12 teachers who require similar kinds of discipline-and grade-level-specific training. Online courses have become an increasingly common way to meet this challenge. This article reports on a randomized control trial that tested…

In 2010, the William and Flora Hewlett Foundation's Education Program has established the Deeper Learning Initiative, which focuses on students' development of deeper learning skills (i.e., the mastery of core academic content, critical-thinking, problem-solving, collaboration, communication, and "learn-how-to-learn" skills). Two test…
