Pattern-oriented instruction (POI) is an instructional computer science (CS) approach that relies on algorithmic patterns (APs). Teaching through APs has been shown to help students acknowledge APs and incorporate them into their solutions, thus demonstrating abstraction skills, and particularly analogical reasoning and problem decomposition. However, further research is required to examine the influence of POI in a wider context, for example, examining the influence of POI on creativity in problem solving and specifically on the diversity of the employed problem-solving strategies.

is taught to computer-science students as part of a comprehensive curriculum. The students encounter the concept of abstraction in various contexts while learning the different modules, each of which emphasizes some specific aspects of the concept. In this paper we present two instructional approaches, both related to utilizing abstraction in problem-solving processes: (1) pattern-oriented instruction (POI), and (2) abstract data type (ADT)-oriented instruction. We present these methods with respect to their employment in teaching problem solving to novices, and elaborate on abstraction processes.

,Abstraction is a major concept in computer science and serves as a powerful tool in software development. Pattern-oriented instruction (POI) is a pedagogical approach that incorporates patterns in an introductory computer science course in order to structure the learning of algorithmic problem solving. This paper examines abstraction processes in the course of solving an algorithmic problem and highlights three distinct, although interrelated, facets of abstraction: pattern recognition, black-boxing, and structure identification. A study that examined the influence of the POI approach on students' abstraction skills is described;students who learned according to the POI approach were compared with students who learned in a traditional manner with regard to analogical reasoning and problem decomposition and solution, as well as verbal expression. The three facets of abstraction were used to analyze students' abstraction skills and their competency in algorithmic problem solving.

An approach to the teaching and learning of high school computer science (CS) to and by educationally disadvantaged students (EDS) is described. We begin by outlining six pedagogical principles for designing learning environments appropriate for EDS. Then, the implementation of one of these principles is presented. Results from years of using the CS module developed based on these principles in Israeli schools show that at the end of the module, the students master basic programming tools and recognize basic algorithmic patterns. These findings indicate the potential contribution of the approach outlined here for EDS.

A Transformation-Based Approach to Developing High-Performance GPU Programs 1

We advocate the use of formal patterns and transformations for programming modern many-core processors like Graphics Processing Units (GPU), as an alternative to the currently used low-level, ad hoc programming approaches like CUDA or OpenCL. Our new contribution is introducing an intermediate level of low-level patterns in order to bridge the abstraction gap between popular high-level patterns (map, fold/reduce, zip, etc.) and imperative, executable code for many-cores. We define our low-level patterns based on the OpenCL programming model which is portable across parallel architectures of different vendors, and we introduce semantics-preserving rewrite rules that transform programs with high-level patterns into programs with low-level patterns, from which executable OpenCL programs are automatically generated. We show that program design decisions and optimizations, which are usually applied ad-hoc by experts, are systematically expressed in our approach as provably-correct transformations for high-and low-level patterns. We evaluate our approach by systematically deriving several differently optimized OpenCL implementations of parallel reduction that achieve performance competitive with OpenCL programs which are manually written and highly tuned by performance experts.

Computers have become increasingly complex with the emergence of heterogeneous hardware combining multicore CPUs and GPUs. These parallel systems exhibit tremendous computational power at the cost of increased programming effort resulting in a tension between performance and code portability. Typically, code is either tuned in a low-level imperative language using hardware-specific optimizations to achieve maximum performance or is written in a high-level, possibly functional, language to achieve portability at the expense of performance. We propose a novel approach aiming to combine high-level programming, code portability, and high-performance. Starting from a high-level functional expression we apply a simple set of rewrite rules to transform it into a low-level functional representation, close to the OpenCL programming model, from which OpenCL code is generated. Our rewrite rules define a space of possible implementations which we automatically explore to generate hardware-specific OpenCL implementations. We formalize our system with a core dependently-typed lambda-calculus along with a denotational semantics which we use to prove the correctness of the rewrite rules. We test our design in practice by implementing a compiler which generates high performance imperative OpenCL code. Our experiments show that we can automatically derive hardware-specific implementations from simple functional high-level algorithmic expressions offering performance on a par with highly tuned code for multicore CPUs and GPUs written by experts.

Novices often experience difficulties in problem analysis and solution construction. Pattern-oriented instruction (POI) is a pedagogical approach based on incorporating patterns into instruction design. It is well-grounded in cognitive theories concerning knowledge construction and organization as well as the acquisition of expertise in problem solving. We show that the incorporation of algorithmic patterns through POI may enhance the construction of algorithmic problem-solving knowledge. Findings of a comparative research study showed that novices who studied according to the POI approach exhibited better problem-solving competence than those who studied in a traditional manner. Specifically, they were more competent in problem decomposition and solution construction.

Techno-Religion and Cyberspace Spirituality in Dystopian Video Games

引用

RELIGIONS 2023年第2期14卷 247-247页

作者： Rupcic, Tijana Cent European Univ Dept Hist A-1100 Vienna Austria

Once a niche part of the cyber community, video games today represent one of the major industries and "the combination of technology and spiritualist narratives". In the cyberspace dedicated to video game trivia, we can find intimate reports of players who claim that video games impacted them spiritually or that they felt unity with the spirit of the universe. By analyzing three video games (Everybody's Gone to the Rapture, Cyberpunk 2077, and Death Stranding), the author aims to explore how spirituality and cyberspace interact in narratives that follow the mentioned games and the interface that pulls the player deeper into the storyline. These games vary in styles and approaches and do not tend to support a view of one true God or any mainstream religion. Therefore, an intricate relationship between cyberspace, algorithmic patterns, and spirituality make these games different and exciting for examination. The author demonstrates the unique perception of spirituality and ideas that influenced the creation of these new spiritual cyberspaces within video games, especially New Age concepts of technopagans such as singularitarians and transhumanists.
