Background and Context: Recursion in binary trees has proven to be a hard topic. There was not much research on enhancing student understanding of this topic. Objective: We present a tutorial to enhance learning through practice of recursive operations in binary trees, as it is typically taught post-CS2. Method: We identified the misconceptions…

The Model of the Use of Evolutionary Trees (MUET)-curricular module that systematically and comprehensively introduces the learning of evolutionary trees for the lower-level college students was developed and implemented in an introductory organismal biology laboratory course at a mid-size, doctoral degree-granting institution. A…

Live video web-streaming via an electronic field trip (EFT) format can connect youth with scientists working in a variety of settings. Previous research indicated interactions with scientists can change children's perceptions of science, technology, engineering, and mathematic (STEM) careers. We conducted an arts-based study to examine an EFT's…

We designed and implemented two instructional approaches to plant education, with the intention of supporting positive attitudes toward plants among sixth-grade students (11-13 years old). In one instructional approach, students prepared a book about plants that have interesting characteristics. In the other approach, students visited a botanical…

Deforestation is a global issue. Education has a fundamental role to play in this context. In this regard, the direction and effectiveness of educational practices should focus on the empowerment of students in ecocentric environmental attitudes. A key point in education for environmental sustainability is pedagogical approaches focused on the…

Payments for ecosystem services (PES) programs use an incentive-based approach to pursue environmental goals. While they are common policy tools, key concepts determining their efficacy are nuanced and hard to grasp. This article presents a new interactive game that explores the functioning and implications of PES programs. Participants play the…

As environmental education and sustainability education play a fundamental role in training citizens who are more aware of global change and more environmentally responsible, organic learning is a recommended alternative learning experience for young children. This article describes how one kindergarten class in South Korea applied organic…

There has been increasing interest in exploring heterogeneous treatment effects using machine learning (ML) methods such as causal forests, Bayesian additive regression trees, and targeted maximum likelihood estimation. However, there is little work on applying these methods to estimate treatment effects in latent classes defined by…

In schools, a lesson functions as an individual building block to support the learning of new material. Experts have identified key elements in an effective lesson, and education leaders--including school based administrators, instructional coaches, department and grade-level chairs--usually look for these elements when reviewing lesson plans and…

Effective usage of augmented reality (AR) depends on good integration into the learning environment. Based on a qualitative research approach, this study investigates the effects of using AR technologies in science education to support the effective use of AR. Students' experiences of AR were gathered using a prepared questionnaire form. Within…

As students learn how to program, both their programming code and their understanding of it evolves over time. In this work, we present a general data-driven approach, named "Temporal-ASTNN" for modeling student learning progression in open-ended programming domains. Temporal-ASTNN combines a novel neural network model based on abstract…

The article aims to expand upon traditional case based instruction through role-play and to explore the effectiveness of the approach in raising students' awareness of the social dimension of the engineering profession. For this purpose, we added a contextual description to the case study "Cutting Roadside Trees" driven by a macroethical…

Understanding phylogenetic trees representing evolutionary relationships of living organisms is essential in school biology. Traditional instructions based on lectures and textbooks with pictorial presentations have been proven ineffective to promote students' understanding of the concept. This study, therefore, developed a game-based learning…

Personalized learning stems from the idea that students benefit from instructional material tailored to their needs. Many online learning platforms purport to implement some form of personalized learning, often through on-demand tutoring or self-paced instruction, but to our knowledge none have a way to automatically explore for specific…

Accurately tracing the state of learner knowledge contributes to providing high-quality intelligent support for computer-supported programming learning. However, knowledge tracing is difficult when learners have only had a few practice opportunities, which is often common in block-based programming. This article proposed two knowledge tracing…
