This evaluation report describes a central professional learning strategy that the California NGSS Early Implementers Initiative used to help teachers effectively transition to the Next Generation Science Standards (NGSS). The Initiative's approach to lesson study, called a Teaching Learning Collaborative (TLC), brings together teams of teachers…

This study came to characterize the features of mathematical models built by mathematics pre-service teachers for a model eliciting activity. Fourteen groups participated in building the models. We used a combination of deductive and inductive content analysis to characterize the pre-service teachers' elicited models, taking into account features…

This study tests a hypothesized learning progression for the concept of energy. It looks at 14 specific ideas under the categories of (i) Energy Forms and Transformations; (ii) Energy Transfer; (iii) Energy Dissipation and Degradation; and (iv) Energy Conservation. It then examines students' growth of understanding within each of these ideas at…

This paper proposes a blended teaching design model on WeChat Platform-based SPOC and carries out an empirical study of its applicability and effectiveness in lower-secondary school science teaching. Participants were from two eighth grade classes with different academic performance, and after conducting the same blended teaching, it was found…

This study is aimed at exploring how different formulations of the same mathematical item may influence students' answers, and whether or not boys and girls are equally affected by differences in presentation. An experimental design was employed: the same stem-items (i.e., items with the same mathematical content and question intent) were…

Chetty et al. (2022) say county density of cross-class friendships (referred to here as "adult-bridging capital") has causal impacts on social mobility within the United States. We instead find that social mobility rates are a function of county density of family capital (higher marriage rates and two-person households), community…

The research aimed to uncover the effect of JiRQA learning a model of based gender on students' achievement at the environmental pollution material. The method was quasi-experimental using of 2 x 2 factorial. The population was all students at junior high school from Ketungau Tengah, Indonesia. The samples were 120 students from two separate…

This study investigates the impact of the problem-based learning (PBL) model on middle school students' environmental literacy and problem-solving skills. A quantitative research study was conducted using a quasi-experimental design for this aim. The sample comprises 114 8th-grade students from a public middle school in Sanliurfa, Turkey. Four…

This study aims to investigate the effect of Toulmin argumentation model (TAM), epistemologically enriched Toulmin argumentation model (EETAM), and method suggested in Turkish Science Curricula on the epistemological beliefs of 7th grade students and their views on this effect. In this context, while the students in TAM group learned seventh grade…

This study focused on finding out the influence of higher order thinking instructional model on grade VIII students' scientific reasoning. The quasi-experimental nonequivalent control group design was used to conduct this study. Experiment was conducted on 62 grade VIII students from a public higher secondary school of district Lahore, Pakistan.…

K-12 school practitioners and schools administrators need reliable results about the effects of instructional technology products as they strive to meet achievement compliance levels in politically accountable local and national contexts in the U.S. This study presents evidence regarding the effects of extensive engagement with computer-based…

The aim of this research was to examine the effect of integration of STEM disciplines into Toulmin's argumentation model on students' academic achievement, reflective thinking, and psychomotor skills. To be able to get this aim, a quasi-experimental method was used. The participants were 40 sixth grade middle school students divided into two…

The impetus for this study occurred when the principal of a secondary Professional Development School (PDS) questioned the traditional teacher education model utilized by the university partner. This principal asked the university to consider a model that better utilized both the teacher candidate and supervising teacher collaboratively to promote…

In this study, whether item position effects lead to DIF in the condition where different test booklets are used was investigated. To do this the methods of Lord's chi-square and Raju's unsigned area with the 3PL model under with and without item purification were used. When the performance of the methods was compared, it was revealed that…

Students preferentially absorb and process information in diverse ways. Pedagogy should vary accordingly. The knowledge of teachers on the learners' preferred learning styles plays a pivotal role in better teaching and learning processes, contributing to a better-quality education. Still, little is known about the preferred learning style of…
