Background/purpose: The purposes of this study were 1) to examine the effectiveness of concept mapping on Grade 10 students' literary analysis skills, 2) to study the participants' satisfaction with concept mapping in learning literary analysis skills, and 3) to establish the construct validity of the learning management plan through confirmatory…

Cosmology concepts encompass complex spatial and temporal relations that are counterintuitive. Cosmology findings, because of their intrinsic interest, are often reported in the public domain with enthusiasm, and students come to cosmology with a range of conceptions some aligned and some at variance with the current science. This makes cosmology…

The purpose of this study is to research the validity and reliability of the Turkish version of Designing my Future Scale developed by Di Maggio et al (2017) for the adolescents. Study had been carried out with 360 students in total who randomly selected from grades 9 and 10 from Namik Kemal High School, Bekir pasa High School and Erenköy High…

This study investigated the effect of situated learning environment in enhancing mathematical reasoning and proof among tenth grade students. To achieve the aim of the study, a pre-posttest of mathematical reasoning and proof was used, and its validity and reliability were verified. The sample of the study consisted of 50 female students who were…

This paper highlights the pedagogical importance of gaps in mathematical proofs to foster students' learning of proofs. We use the notion of 'gap-filling' (Perry & Sternberg, 1986) from literary theory to analyze a task based on a Proof Without Words, which epitomizes the notion of gaps. We demonstrate how students fill in gaps in this…

Students' science identity has been identified as an important construct that positively influences their learning engagement, persistence, and career intentions in science. This paper reported the process of developing and validating an instrument that can be used to assess high school students' science identity. The development of this…

We investigated environmental supports, an understudied aspect of Social Cognitive Career Theory (SCCT), with rural Appalachian youth, an understudied population. We developed a new measure of proximal influences that bolster the pursuit of postsecondary education, the Assessment of Postsecondary Supports (APSS). Across 3 studies, we develop and…

Constructing formal geometry proofs in is an important topic in the mathematics curriculum. But students' difficulties with proof are well documented. This article focuses on proofs that use triangle congruence postulates in US high school geometry. Examining students' proof reasoning in one-on-one task-based interviews, we analyzed students' oral…

This quantitative study developed a measurement instrument, The Assessment of Historical Perspective-Taking (AHPT), to evaluate historical perspective-taking skills among 15- and 16-year-old students within their United States History classes by adapting an existing measurement instrument developed in Germany. Applying a theoretical framework that…

Character measurement has become increasingly relevant and needed in recent years due to its significant impact on an individual's success in various aspects of life. However, existing methods of character measurement such as self-assessment, peer assessment, and observation, still have many limitations. The Situational Judgement Test (SJT) is a…

This study developed a scale to assess high school students' programming disposition. The scale was developed by utilizing a standardized test development process. The three constructs of the scale, namely confidence, persistence and flexible thinking, consisted of 9 items (3 items on each construct). Participants for the formal test of the scale…

Background: In many countries and regions, such as the United States, Europe and China, a trend has emerged in which students' enthusiasm for STEM is declining. This decline may be related to students' lack of science self-efficacy. An accurate examination of students' science self-efficacy can provide a research foundation for how to cultivate…

Because there has been very little past research into gifted students' science learning environments, especially in Singapore, we selected from four established questionnaires six learning environment scales that are consistent with Van Tassel-Baska and Stambaugh's guidelines for gifted education. These scales were modified slightly to enhance…

The main purpose of this study was to design and verify the quality of an assessment aimed at diagnosing scientific misconceptions among students enrolled in 10th-grade biology subjects. A sample consisted of N=200 students from schools under the administration of the Office of Secondary Educational Service 31, Nakhon Ratchasima province. We…

This study aims to discover the effectiveness of the blended learning model in mathematics learning to improve the achievement of mathematical concepts. This study employed a quasi-experimental design with a non-equivalent control group. The experimental class was taught through blended learning, while the control class was taught through the…
