This research focuses on students' tactic assessments of 3 correlations with illustrated 2-step strategic map and animated presentations in stoichiometry. The participants were divided into 2 learning groups: the experimental and the control group by quasi-experimental approach. Most of all, experimental group participants have been contingent on…

Separation of variables can be a powerful technique for solving many of the partial differential equations that arise in physics contexts. Upper-division physics students encounter this technique in multiple topical areas including electrostatics and quantum mechanics. To better understand the difficulties students encounter when utilizing the…

The release of the "NRC Framework for K-12 Science Education" and the "Next Generation Science Standards" has important implications for classroom teaching and assessment. Of particular interest is the implementation of science practices in the chemistry classroom, and the definitions established by the NRC makes these…

Curricular coherence is an indication of the alignment of content ideas, the depth at which they are studied, and the sequencing of ideas within and across grade levels and has been identified as an important predictor of student performance. This study examined the contribution of inter-unit coherence on energy to the learning of this concept…

Longitudinal studies can provide significant insights into how students develop competence in a topic or subject area over time. However, there are many barriers, such as retention of students in the study and the complexity of data analysis, that make these studies rare. Here, we present how a statistical framework, discrete-time survival…

Introductory chemistry has long been considered a service course by various departments that entrust chemistry departments with teaching their students. As a result, most introductory courses include a majority of students who are not chemistry majors, and many are health and science related majors who are required to take chemistry. To identify…

Multiple-choice (MC) items that are constructed such that distractors target known misconceptions for a particular domain provide useful diagnostic information about student misconceptions (Herrmann-Abell & DeBoer, 2011, 2014; Sadler, 1998). Item response theory models can be used to examine misconceptions distractor-driven multiple-choice…

This study employs a potential outcomes modeling approach to estimate the causal effect of the National Math + Science Initiative's College Readiness Program on Advanced Placement test taking and qualifying score earning for three recent cohorts of schools. Results indicate substantial and significant increases in both AP test taking and…

The Regulations of the Commissioner of Education provide that an elementary-level science test is to be administered in Grade 4 to serve as a basis for determining students' needs for academic intervention services in science. The New York State Grade 4 Elementary-Level Science Test consists of two required components: a Written Test and a…

This study developed a computer-simulated science inquiry environment, called the Science Detective Squad, to engage students in investigating an electricity problem that may happen in daily life. The environment combined the simulation of scientific instruments and a virtual environment, including gamified elements, such as points and a story for…

The overarching purpose of our study was to compare performances of treatment and control condition students who completed a literacy-infused, inquiry-based science intervention through sixth grade as measured by a big idea assessment tool which we refer to as the Big Ideas in Science Assessment (BISA). First, we determine the concurrent validity…

The purpose of this study is to examine the effects of different modes of competition on science learning in a game-based learning (GBL) environment. Some key motivational constructs such as learning goals, performance goals, and perceived ability were also investigated. One hundred ninety-five students from a secondary school in Taiwan were…

This study examines the influence of laboratory instruction that engages students in a wide range of the practices of science on Turkish high-school students' chemistry learning. In this mixed methods study, student learning in two different laboratory settings was compared, one that featured an instruction that engaged students in a wide range of…

This study examined the relationships among school leadership practices, parental involvement, disciplinary climate, students' perceptions on reading, and student achievement with sample obtained from the combined data of Progress in International Reading Literacy Study (PIRLS) and Trends in International Mathematics and Science Study (TIMSS) 2011…

Pearson sought to explore whether the use of Mastering Biology, an online tutorial system used in higher education general introductory courses, is related to students' exam results. This Research Report presents findings from one research study: a correlational study we conducted at a North American state-related, land-grant, doctoral university,…
